For many years, I lived in the Indian city of Chennai where the summer temperatures can reach up to 44°C. With a population of 4.5 million, this coastal city is humid and hot.

Its suburbs are home to 600 Hindu temples and there’s a wildlife reserve called Guindy national park in the heart of the city. of the streets but green parks are few and far between – as is the shade.

As and the rest of , urban forests become more vital. These clusters of trees in parks, gardens, public spaces and along roads and rivers have multiple benefits – from cooling the surrounding air to providing homes for wildlife and creating space for people to enjoy nature. Yet they are often overlooked by city developers.

shows that, in Chennai, there are 26 square miles of tree and other vegetation cover, mainly accounted for by formal green spaces such as Guindy wildlife reserve. On the outskirts of this city, an area of nine square miles of unused land is ideally suited to creating more urban forest. Similarly, there is more potential space for urban forests in other fast urbanising Indian cities like Coimbatore and Tiruchirapalli.

recommend having at least 30% tree cover in urban areas. suggests that cities should allow for nine square metres of urban tree cover per person. Most Indian cities .

Improving urban forests in India has been a challenge for many years due to high land prices, lack of urban planning and little public participation .

Policies introduced by the Indian government to “green” urban areas often equate tree planting with cooling cities and building climate resilience. But it’s not that simple. The success of urban forests depends on factors such as rainfall, understanding interactions with local wildlife and people’s needs.

A warns that in hot, dry cities with limited water availability like Chennai, trees slow the cooling process by water evaporation from leaves and instead contribute to urban heat. Urban heat comes from the reflection and absorption of sunlight by buildings and land surfaces. This is particularly high in smaller Indian cities with populations of 1 to 5 million.

Planting trees with the sole aim of cooling cities could negatively affect wildlife too. Not all birds, bugs and mammals depend on trees for food or shelter. A from researchers in Bengaluru, India, shows that non-native tree species contribute little to bird richness. Meanwhile, urban grasslands and marshlands that are often misclassified as “waste land” support wildlife and help regulate flooding.

In India, cities and villages have open “common” land where people graze their cattle or harvest fuelwood from trees that grow naturally there – tree-planting initiatives in these open land areas can displace poorer communities of people who rely on open lands for grazing and fuel wood collection.

Design with nature

Urban forests can be planned to meet the needs of people, birds and other wildlife.

In 1969, Ian McHarg, the late Scottish landscape architect and urban planner came up with the concept of “design with nature”, where development has a minimal negative effect on the environment. His idea was to preserve existing natural forests by proposing site suitability assessments. By analysing factors such as rivers and streams, soil type, slope and drainage, to identify which areas suit development and which are best preserved for nature.

This approach has advanced with new technology. Now, geographic information systems and satellite imagery help planners integrate environmental data and identify suitable areas for planting new trees or conserving urban forests.

Using the principles of landscape ecology, urban planners can design forest patches in a way that enhances the connectivity of green spaces in a city, rather than uniformly planting trees across all open spaces. By designing these “ecological corridors”, trees along roads or canals, for example, can help link fragmented green spaces.

Planting native tree species suited to dry and drought-prone environments is also crucial, as is assessing the local community’s needs for native fruit-bearing trees that provide food.

Growing urban forests

By 2030, one-third of India’s electricity demand is expected to come from cooling equipment such as . Increasing urban forests could help reduce this .

National-level policies could support urban forest expansion across India. In 2014, the government of India released its urban greenery and flagship urban renewal programmes such as the have tried to increase tree cover. But guidelines often overlook critical considerations like ecological connectivity, native species and local community needs.

In 2020, the government of India launched (a scheme to improve tree cover in cities) with a budget of around US$94 million (£70 million). It aims to create urban forests through active participation of citizens, government agencies and private companies. But there is little evidence that urban forest cover has improved.

Urbanisation reduced tree cover in most Indian cities, and much of it was rather . But by protecting and planting more trees, citizens can live in greener, cooler cities. By shifting urban forest policy from counting trees to designing landscapes, plans that enhance climate resilience, nature conservation and social equity can be put into practice.

Beyond advancing ecological science, the research could provide vital tools for tracking soil carbon storage, monitoring land degradation, and supporting sustainable land management in the face of climate change.

The Ganges, a lifeline for hundreds of millions across South Asia, is drying at a rate scientists say is unprecedented in recorded history. , shifting monsoons, relentless extraction and damming are pushing the mighty river towards collapse, with consequences for food, water and livelihoods across the region.

For centuries, the Ganges and its tributaries have sustained one of the world’s most densely populated regions. Stretching from the Himalayas to the Bay of Bengal, the whole river basin supports over 650 million people, a quarter of India’s freshwater, and much of its food and economic value. Yet new research reveals the river’s decline is accelerating beyond anything seen in recorded history.

In recent decades, scientists have documented across many of the world’s big rivers, but the Ganges stands apart for its speed and scale.

In a , scientists reconstructed streamflow records going back 1,300 years to show that the basin has faced its worst droughts over the period in just the last few decades. And those droughts are well outside the range of natural climate variability.

Stretches of river that once supported year-round navigation are now impassable in summer. Large boats that once travelled the Ganges from Bengal and Bihar through Varanasi and Allahabad now run aground where water once flowed freely. Canals that used to irrigate fields for weeks longer a generation ago now dry up early. Even some wells that protected families for decades are yielding little more than a trickle.

Global climate models have failed to predict the severity of this drying, pointing to something deeply unsettling: human and environmental pressures are combining in ways we don’t yet understand.

Water has been diverted into irrigation canals, groundwater has been pumped for agriculture, and industries have proliferated along the river’s banks. More than a thousand dams and barrages have radically altered the river itself. And as the world warms, the monsoon which feeds the Ganges has grown increasingly erratic. The result is a river system increasingly unable to replenish itself.

Melting glaciers, vanishing rivers

At the river’s source high in the Himalayas, the Gangotri glacier has retreated in just two decades. The pattern is repeating across the world’s largest mountain range, as rising temperatures are melting glaciers faster than ever.

Initially, this brings . In the long-run, it means far less water flowing downstream during the dry season.

These glaciers are often termed the “water towers of Asia”. But as those towers shrink, the summer flow of water in the Ganges and its tributaries is dwindling too.

Humans are making things worse

The reckless extraction of is aggravating the situation. The Ganges-Brahmaputra basin is one of the most rapidly depleting aquifers in the world, with water levels falling by . Much of this groundwater is already contaminated with arsenic and fluoride, threatening both human health and .

The role of human engineering cannot be ignored either. Projects like the in India have reduced dry-season flows into Bangladesh, making the land saltier and threatening the Sundarbans, the world’s largest mangrove forest. Decisions to prioritise short-term economic gains have undermined the river’s ecological health.

Across and West Bengal, smaller rivers are already drying up in the summer, leaving communities without water for crops or livestock. The disappearance of these smaller tributaries is a harbinger of what may happen on a larger scale if the Ganges itself continues its downward spiral. If nothing changes, experts warn that millions of people across the basin could face within the next few decades.

Saving the Ganges

The need for urgent, coordinated action cannot be overstated. Piecemeal solutions will not be enough. It’s time for a comprehensive rethinking of how the river is managed.

That will mean reducing unsustainable extraction of groundwater so supplies can recharge. It will mean environmental flow requirements to keep enough water in the river for people and ecosystems. And it will require improved climate models that integrate human pressures (irrigation and damming, for example) with monsoon variability to guide water policy.

Transboundary cooperation is also a must. India, Bangladesh and Nepal must do better at sharing data, managing dams, and planning for climate change. International funding and political agreements must treat rivers like the Ganges as global priorities. Above all, governance must be inclusive, so local voices shape river restoration efforts alongside scientists and policymakers.

The Ganges is more than a river. It is a lifeline, a sacred symbol, and a cornerstone of South Asian civilisation. But it is drying faster than ever before, and the consequences of inaction are unthinkable. The time for warnings has passed. We must act now to ensure the Ganges continues to flow – not just for us, but for generations to come.

The study sets out clear recommendations for further improvements, based on direct community feedback. These insights are expected to inform future active travel strategies both locally and nationally.

The full report is available here: .

While pollution levels from road traffic have fallen significantly thanks to policies like the Ultra Low Emission Zone (ULEZ), new air pollution data from scientists at �������Թϱ���, in collaboration with the UK Centre for Ecology & Hydrology (UKCEH), University of York, Zhejiang University and National Centre for Atmospheric Science, reveal emissions from non-road mobile machinery, such as generators and heavy-duty construction equipment, can exceed those from vehicles, particularly in areas where there is a lot of building activity.

Black carbon is soot from combustion and is a component of particulate matter (PM2.5). These are very fine particles that can enter the lungs and bloodstream and are known to damage human health. 

The team collected the pollution measurements from the top of the BT Tower in central London over summer and winter, using a technique called eddy covariance to track how much black carbon is released into the air and where it comes from.

The findings revealed that while pollution levels were significantly lower than cities like Beijing and Delhi, who have monitored pollution using the same method, they are not low enough to meet the . They suggest similar regulatory attention to road traffic is now needed for the construction sector. 

The study, published in the journal is the first of its kind in Europe.

At 190 metres tall, the BT Tower observatory has a specialised gas inlet system installed on the tower’s roof, which draws air into a laboratory on the 35th floor, allowing researchers to analyse pollution as it rises from streets, buildings, construction sites and nearby parks below.

The ‘eddy covariance’ method works by measuring the turbulent motion of air, also known as eddies, and the concentration of airborne substances like black carbon within those eddies.

The scientists also conducted a detailed spatial footprint analysis to pinpoint emission hotspots that were directly linked to active construction sites near the BT Tower.

The new findings suggest that further progress in improving London’s air quality will require stricter regulation of construction machinery, especially in rapidly developing areas.

added: “We compared observed emissions with emission standards for construction equipment and found that even with compliance, black carbon output from generators, machinery and construction vehicles remains significant. Our work highlights how measurement techniques like eddy covariance can fill critical gaps in our understanding of urban pollution and support evidence-based strategies to protect public health and the environment.”

As the UK strives to reach Net Zero emissions by 2050, secure and permanent geological storage of CO₂ is essential to avoid the worst-case consequences of climate change.

Storage in deep geological formations such as depleted oil and gas reservoirs and saline aquifers offers a promising solution. However, these underground environments host diverse microbial ecosystems, and their response to CO₂ injection remains poorly understood.

This knowledge gap poses a potential risk to long-term CO₂ storage integrity. While some microbial responses may be beneficial and enhance mineralogical or biological CO₂ sequestration, others could be unfavourable, leading to methane production, corrosion of infrastructure, or loss of injectivity.

The new flagship project with �������Թϱ��� and Equinor - global leaders in geological CO₂ storage - will investigate how subsurface microbial communities respond to CO₂ injection and storage, highlighting both the potential risks and opportunities posed by these microbes.

Principal Investigator, Prof Sophie Nixon, BBSRC David Phillips and Dame Kathleen Ollerenshaw Fellow at �������Թϱ���, said: "Over the past 20 years, scientists have tested storing CO₂ underground in real-world conditions, but we still know little about how this affects native and introduced microbes living deep below the surface.

"Previous studies have shown that injecting CO₂ underground actively changes microbial communities. In some cases, microbes initially decline but later recover, potentially influencing the fate of injected CO₂ in geological storage scenarios. However, these studies predate the advent of large-scale metagenomic sequencing approaches. A deep understanding of who is there, what they can do and how they respond to CO₂ storage is crucial for ensuring the long-term success of carbon capture and storage."

The two-year project will collect samples from saline aquifer and oil producing sites to study how microbes living deep underground respond to high concentrations of CO₂ by combining geochemistry, gas isotope analysis, metagenomic and bioinformatic approaches.

Project Co-Investigator, Dr Rebecca Tyne, a Dame Kathleen Ollerenshaw Fellow at �������Թϱ���, said: “To date, Carbon Capture and Storage research has focused on the physiochemical behaviour of CO₂, yet there has been little consideration of the subsurface microbial impact on CO₂ storage. However, the impact of microbial processes can be significant. For instance, my research has shown that methanogenesis may modify the fluid composition and the fluid dynamics within the storage reservoir.”

Currently, the North Sea Transition Authority requires all carbon capture and storage sites to have a comprehensive ‘Measurement, Monitoring and Verification’ strategy, but microbial monitoring is not yet included in these frameworks. The project’s findings will be shared with industry stakeholders and published in leading scientific journals, helping to close this critical gap and shape future operational activities.

Project Lead, Leanne Walker, Research Associate in Subsurface Microbiology at �������Թϱ���, said: "This project will help us understand the underground microbial communities affected by CO₂ storage—how they respond, the potential risks and benefits, and the indicators that reveal these changes.

"Our findings will provide vital insights for assessing microbiological risks at both planned and active CCS sites, ensuring safer and more effective long-term CO₂ storage”.

The treaty suspension reflects a growing regional trend: South Asian countries are increasingly treating water as a strategic asset rather than a shared resource amid rising mistrust, climate stress and geopolitical competition.

The region is home to nearly a quarter of the global population, and relies on huge transboundary rivers fed by Himalayan glaciers – the so-called of freshwater reserves. A breakdown in water diplomacy could trigger environmental collapse, humanitarian crises and geopolitical instability. The weaponisation of water must be urgently addressed as a global climate justice issue.

A flashpoint occurred in August 2024 when devastating floods affected in Bangladesh. Some Bangladeshi officials accused India of releasing excess water from a large dam upstream without warning. India , citing extreme rainfall and standard dam operations. Nevertheless, the incident reignited longstanding tensions between the two countries.

Complicating matters further is China recently approving the construction of the on the Yarlung Tsangpo river in Tibet, which becomes the Brahmaputra in India. This massive project has about China’s ability to exert control upstream, and the ecological risks for India and Bangladesh downstream.

China hasn’t signed formal water-sharing agreements with its neighbours, but its growing presence in regional water infrastructure signals a dramatic shift in south and east Asian hydro-politics.

Climate change is making things worse

Recent climatic trends are making transboundary rivers an increasing focus of geopolitical friction. These trends include accelerated , , and intensifying extreme weather.

While melting glaciers will temporarily boost the flow of rivers, the long-term prognosis is bleak. If emissions and warming trends continue, many glacier-fed rivers – including the Indus, Ganges and Brahmaputra – could see by the end of the century. This will directly affect hundreds of millions of people who depend on them.

The crisis is being intensified by changes in the Himalayas. The region is warming faster than the global average, with a shift from snowfall to rainfall that disrupts the timing and volume of water that flows down from the mountains to the fields and cities below.

At the same time, has pushed South Asia’s reserves of underground water toward collapse, threatening both food and water security.

A dangerous precedent

A collapse or suspension of the Indus Waters Treaty could set a dangerous precedent. Importantly, the threat is less about India cutting off water flows – an unlikely and technically challenging act – and more about the erosion of trust, transparency and data sharing.

One of the treaty’s most valuable features has been the routine sharing of data on things like water levels, river flow and dam operations. Pakistan needs this data to forecast floods and droughts, plan its irrigation, generate hydropower effectively and manage its drinking water, yet India is indicating it will no longer honour these obligations.

But India’s strained water relations are not limited to Pakistan. Bangladesh and Nepal have often felt sidelined or pressured in negotiations, and India’s indication that it may reconsider longstanding treaties raises concerns in both countries.

This is especially the case as the Ganges Water Treaty nears its 2026 expiration: the vast Ganges river flows through India and irrigates much of Bangladesh – and the treaty guarantees Bangladesh a minimum river flow.

Other key agreements, such as the and with Nepal, and the with Bangladesh, remain largely unimplemented, breeding mistrust. These failures undermine confidence in regional water diplomacy and cast doubt on India’s commitment to equitable cooperation.

None of this is helped by India, Pakistan and Bangladesh all continuing to rely on outdated irrigation methods that mean they use more water than necessary. As climate change intensifies floods, droughts and glacial melt, there is an urgent need to reform existing water treaties to reflect present-day climate, hydrological and geopolitical realities.

The Indus Waters Treaty, negotiated in the 1960s before the emergence of modern climate science, no longer accounts for these transformations. Indeed, most water treaties in the region remain rooted in technocratic, engineering-centric frameworks which fail to address extreme climate variability and its cascading impacts.

The upcoming expiration of the Ganges Water Treaty, and the pending negotiation of other basin agreements, present a critical opportunity to rethink water governance in South Asia.

Though the Indus flows through India before Pakistan, in other basins, India is downstream. This is the case with the Brahmaputra, where it demands upstream cooperation from China.

Undermining the Indus treaty could weaken India’s own position in future negotiations and strain its relations with Nepal and Bangladesh, while giving China more influence in South Asian hydro-politics. China is already expanding its footprint by offering billions in loans to Bangladesh and strengthening ties with Nepal, particularly around water infrastructure.

Weaponising water is a perilous strategy that may backfire. The weakening of water diplomacy in South Asia is not just a regional threat; it endangers global climate security.

In the face of escalating climate change impacts and recurring disasters, updating transboundary agreements like the Indus Waters Treaty, Ganga Water Treaty, and Kosi and Teesta accords is no longer optional – it is an urgent necessity with enormous consequences.

China recently of the world’s largest hydropower dam, across the Yarlung Tsangpo river in Tibet. When fully up and running, it will be the world’s largest power plant – by some distance.

Yet many are worried the dam will displace local people and cause huge environmental disruption. This is particularly the case in the downstream nations of India and Bangladesh, where that same river is known as the Brahmaputra.

The proposed dam highlights some of the geopolitical issues raised by rivers that cross international borders. Who owns the river itself, and who has the right to use its water? Do countries have obligations not to pollute shared rivers, or to keep their shipping lanes open? And when a drop of rain falls on a mountain, do farmers in a different country thousands of miles downstream have a claim to use it? Ultimately, we still don’t know enough about these questions of river rights and ownership to settle disputes easily.

The Yarlung Tsangpo begins on the Tibetan Plateau, in a region sometimes referred to as the world’s third pole as its glaciers contain the largest stores of ice outside of the Arctic and Antarctica. A series of huge rivers tumble down from the plateau and spread across south and south-east Asia. Well over a billion people depend on them, from Pakistan to Vietnam.

Yet the region is already under immense stress as global warming melts glaciers and changes rainfall patterns. Reduced water flow in the dry season, coupled with sudden releases of water during monsoons, could intensify both water scarcity and flooding, endangering millions in India and Bangladesh.

The construction of has historically disrupted river flows, displaced people, destroyed fragile ecosystems and increased risks of floods. The Yarlung Tsangpo Grand Dam will likely be no exception.

The dam will sit along the tectonic boundary where the Indian and Eurasian plates converge to form the Himalayas. This makes the region particularly vulnerable to earthquakes, , and .

Downstream, the Brahmaputra is one of south Asia’s mightiest rivers and has been integral to human civilisation for thousands of years. It’s one of the world’s most sediment-rich rivers, which helps form a huge and fertile delta.

Yet a dam of this scale would trap massive amounts of sediment upstream, disrupting its flow downstream. This could make farming less productive, threatening food security in one of the world’s most densely populated regions.

The Sundarbans mangrove forest, a Unesco World Heritage Site that stretches across most of coastal Bangladesh and a portion of India, is particularly vulnerable. Any disruption to the balance of sediment could accelerate coastal erosion and make the already low lying area more vulnerable to sea-level rise.

Unfortunately, despite the transboundary nature of the Brahmaputra, there is no comprehensive treaty governing it. This lack of formal agreements complicates efforts to ensure China, India and Bangladesh share the water equitably and work together to prepare for disasters.

These sorts of agreements are perfectly possible: 14 countries plus the European Union are parties to a , for instance. But the Brahmaputra is not alone. Many transboundary rivers in the global south face similar neglect and inadequate research.

Researching rivers

In our recent study, colleagues and I analysed . We wanted to assess how much academic research there was on each, what themes it focused on, and how that varied depending on the type of river. We found that, while large rivers in the global north receive considerable academic attention, many equally important rivers in the global south remain overlooked.

What research there is in the global south is predominantly led by institutions from the global north. This dynamic influences research themes and locations, often sidelining the most pressing local issues. We found that research in the global north tends to focus on technical aspects of river management and governance, whereas studies in the global south primarily examine conflicts and resource competition.

In Asia, research is concentrated on large, geopolitically significant basins like the Mekong and Indus. Smaller rivers where water crises are most acute are often neglected. Something similar is happening in Africa, where studies focus on climate change and water-sharing disputes, yet a lack of infrastructure limits broader research efforts.

Small and medium-sized river basins, critical to millions of people in the global south, are among the most neglected in research. This oversight has serious real-world consequences. We still don’t know enough about water scarcity, pollution, and climate change impacts in these regions, which makes it harder to develop effective governance and threatens the livelihoods of everyone who depends on these rivers.

A more inclusive approach to research will ensure the sustainable management of transboundary rivers, safeguarding these vital resources for future generations.

For years, nature has been blamed as a blocker of economic growth. After some ministerial about not letting get in the way of growth ambitions, the UK government released more details of its plans to .

The centrepiece of its aspirations to balance both nature and economic growth is a , to be set up in England through changes to habitat regulations. This should allow developers to stay within their legal obligations towards nature through a payment scheme without delaying their projects.

The is that, as an alternative to relocating important species or improving habitats on the site of a proposed development, a developer could pay into the nature restoration fund. This would pay for larger, more strategically located schemes to protect the species in question.

The fund simplifies and streamlines the regulations while collecting funds to promote more, bigger, better and increasingly .

Protecting nature is not just about bats and newts. According to trade association the Home Builders Federation (HBF), there are 160,000 homes being delayed by what are known as measures. These rules were a response to growing public concerns about land and water pollution caused by nutrient loads – pollutants such as nitrogen and phosphorus – associated with livestock farming and spillages from sewage works.

Government agency 74 local authorities that they should not allow any more house building in their areas unless this pollution could be mitigated. But this has led to lengthy and expensive project-by-project reviews to identify potential damage.

How will a fund help?

The fund will build on some schemes that are already known to work. One such scheme works for the protection of . Another successful scheme is project, working to protect and enhance heathland sites where rare birds such as nightingales breed. Crucially, this scheme allows new development to go ahead in adjacent areas.

The fund will be run by Natural England, which aims to draw on these experiences to unblock development at a large scale rather than at single-site level, pooling contributions from developers to pay for mitigation measures when there is a risk to nature.

If a particular “blocking” issue is identified, experts from Natural England will produce a plan, which must be approved by the environment secretary. A levy on developers will then pay for mitigation measures “in perpetuity” (often 30 years), allowing the development to get under way.

Environmental experts have the general principles and approach of the nature restoration fund. But there has also been about whether the plan is well enough thought through. There are also questions on how well it will integrate with other schemes.

A widespread worry is for the future of – which includes measures for creating and improving using biodiversity units, effectively a form of “nature market”. This approach sets a target of 10% for biodiversity improvement based upon the combined distinctness, condition and significance of affected habitats over the lifetime of the development. But these measures are only just .

The concern is that providers of sites for these habitat banks – which might be councils, landowners, charities or private businesses, for example – might get cold feet and if they can’t be certain that their plans will be compatible with the nature restoration fund.

There is concern, too, about how payments from the nature restoration fund would be calculated. These will need to be locally appropriate and not pit nature restoration and biodiversity net gain against each other if, for example, landowners are forced to choose a particular scheme for their land that they are then . With two parallel systems in play, the relationship between them must be crystal clear, otherwise shared goals could be missed.

Another question is whether Natural England can be both regulator and financial beneficiary of the new scheme. There have been calls from some of those already involved in nature markets for some form of .

And it will also be vital that the new scheme respects what’s known as the “mitigation hierarchy”. This hierarchy aims to avoid, reduce and then mitigate any impacts on nature on-site in that order. Then developers should consider off-site measures in areas where there could be greater .

But a danger here is that this could disconnect people from nature even further by mitigating ecological loss miles away from the site of the damage. This disconnection is considered to be a critical underlying cause of .

There is much to like about the nature restoration fund, but there is a risk that little will be achieved without the government showing genuine ambition and allocating enough money and staff to properly monitor and enforce it over the long term. Only time will tell whether it achieves the government’s goal of speeding up development.

At the moment, it is not clear how the fund will complement similar schemes and there is a danger of creating a complex patchwork in nature restoration funding. But if it works well, it could provide a richer funding ecosystem for nature recovery – a much-needed boost for England’s nature-depleted landscape.

The findings, published in the journal ,  show that these powerful flows could be capable of traveling at speeds of up to eight meters per second, carrying plastic waste from the continental shelf to depths of more than 3,200 meters.

Over 10 million tonnes of plastic waste enter the oceans each year. While striking images of floating debris have driven efforts to curb pollution, this visible waste accounts for less than 1% of the total. The missing 99% – primarily made up of fibres from textiles and clothing – is instead sinking into the deep ocean.

Scientists have long suspected that turbidity currents play a major role in distributing microplastics across the seafloor – �������Թϱ��� were among the first to demonstrate this through their research on ‘Microplastic Hotspots’ in the Tyrrhenian Sea, published in the journal . However, until now, the actual process had not been observed or recorded in a real-world setting.

The latest study conducted by �������Թϱ���, the National Oceanography Centre (UK), the University of Leeds (UK), and the Royal Netherlands Institute for Sea Research provides the first field evidence showing the process.

The findings pose a significant threat to marine ecosystems and highlight the urgent need for stronger pollution controls.

Dr Peng Chen, lead author on the study at �������Թϱ���, said “Microplastics on their own can be toxic to deep-sea life, but they also act as ‘carriers’ transferring other harmful pollutants such as PFAS ‘forever chemicals’ and heavy metals, which makes them an environmental ‘multistressor’ which can affect the entire food chain.”

The research focused on Whittard Canyon in the Celtic Sea, a land-detached canyon over 300 km from the shore. By combining in-situ monitoring and direct seabed sampling, the team were able to witness a turbidity current in action, moving a huge plume of sediment at over 2.5 metres per second at over 1.5 km water depth. The samples directly from the flow revealed that these powerful currents were not only carrying just sand and mud, but a significant quantity of microplastic fragments and microfibres.

Further analysis found that the microplastics on the seafloor are mainly comprised of fibres from textiles and clothing, which are not effectively filtered out in domestic wastewater treatment plants and easily enter rivers and oceans.

, Geologist and Environmental Scientist at �������Թϱ���, who designed and led the research, said: “These turbidity currents carry the nutrients and oxygen that are vital to sustain deep-sea life, so it is shocking that the same currents are also carrying these tiny plastic particles.

“These biodiversity hotspots are now co-located with microplastic hotspots, which could pose serious risks to deep-sea organisms.

“We hope this new understanding will support mitigations strategies going forward.”

Dr Mike Clare of the , who was a co-lead on the research, added: “Our study has shown how detailed studies of seafloor currents can help us to connect microplastic transport pathways in the deep-sea and find the ‘missing’ microplastics. The results highlight the need for policy interventions to limit the future flow of plastics into natural environments and minimise impacts on ocean ecosystems.”

The study team are now focussing on efforts to better understand the effect that microplastics have on marine organisms, for example sea turtles and deep-sea fauna.

This research was published in the journal Environmental Science and Technology.

The scientists also found slightly less, but still significant levels of microplastics in other organs of both male and female turtles, including the heart, kidney, liver and spleen, as well as skeletal muscle, subcutaneous fat, stomach and intestines.

They studied the bodies of 10 stranded loggerhead sea turtles, recovered by the Oceanogràfic Foundation of Valencia, that suffered drowning and exhaustion when they were accidently caught up in commercial fishing nets. 

The findings, published in the journal , could spell disaster for the majestic creatures already found in declining numbers in the world’s oceans.

It is the first study to show that microplastics from the gut can translocate in sea turtles, opening up the possibility of different organs  especially the reproductive system -  being directly affected.

The scientists believe microplastics may also lead to systemic inflammation  in the animals.

The largest median particle size  of around 25 microns was found in the intestines and fat, and the smallest median particle size  - of around 15 microns was found in the stomach and reproductive organs.

Lead author Leah Costello, a PhD researcher from �������Թϱ��� was funded under a Biotechnology and Biological Sciences Research Council Doctoral Training Studentship. 

She said: “Microplastics are a pervasive marine environmental pollutant, on a par with other global threats such as climate change and ozone depletion. 

“Our study is the first to show direct evidence of the presence of microplastics in the reproductive and other organs of loggerhead sea turtles.

“Sea turtles already face many pressures from human activity and although we have been aware that they ingest plastic throughout their range, the finding of microplastics in almost every tissue sample was quite shocking.

“These findings show that even seemingly healthy individuals could be under physiological stress, impacting the reproductive success of vulnerable and recovering populations.”

Foreign microparticles were identified in 98.8% of all samples, of which around 70% were  microplastics. 

Analysis revealed that polypropylene, polyester fibres, and polyethylene were the most common microparticle types. 

Polypropylene is used in include food packaging, clothing, bottle caps, ropes, personal care products, fishing gear and twine. 

Loggerhead turtles are regularly reported to ingest plastic bags  - made from polyethylene -  who misidentify them as  jellyfish and algae. 

Polyester is another dominant microfiber releasing large numbers of microfibres into the oceans and seas. 

And further analysis provided direct visualisation of cotton microfibres embedded in loggerhead heart tissue.

 Three million tonnes of primary microplastics are released into environment every year, with a further 5.3 million tonnes of larger plastic items that can degrade into secondary microplastics over time.

Because plastics can remain in the gut for up to four months in sea turtles, the scientists speculate that microplastics can cross biological barriers from the gut to organs via the circulatory system contributing to a suite of adverse biological effects.

Co-author Professor Holly Shiels from the University of �������Թϱ���  added: “Microplastic accumulation is likely to be associated with organ damage and toxicity in these incredible marine reptiles that can live for 70 years.

“Of particular concern is the impact on reproduction, with implications on growth, development and viability of offspring which could spell trouble for the stability of these already vulnerable sea turtle populations. 

“However, further studies are required to more broadly assess the biological and health impacts of microplastic on sea turtle reproduction.”

The UK government has published its , a cornerstone of its strategy for growth. The bill aims to and includes the hugely ambitious target of building in England over this parliament.

The bill is ambitious in scope – 160 pages long and very technical. But what does it promise exactly?

On , it outlines reforms to limit vexatious repeat use of judicial review to block development. There are also some measures for a stronger electricity grid to ease the move towards renewable energy. While the plan to reward people living with £250 off their bills grabbed headlines, just as important are measures for energy storage to level out peaks in demand and supply.

On the side, planning departments will be allowed to charge more to those making applications. This should speed up decisions by funding more planning officer roles. But there are no measures to increase funding for drawing up local plans. This is important because councils often fall behind schedule in producing these. And where there is no up-to-date plan, there is a danger that developers will push through controversial proposals.

The bill also provides for more decisions to be delegated to planning officials rather than planning committees – this means council staff rather than elected representatives. This already happens for smaller planning applications, so is not entirely new. But it does raise concerns about democratic scrutiny.

The government argues that local democracy will not be undermined, as planning officers will be making their decisions in the context of democratically approved local plans as well as national legislation. But this could be misleading, unless planning authorities have the funds to update local plans regularly.

There are also changes to existing legislation, to support the building of new towns. Particularly welcome is the responsibility on development corporations – government organisations dealing with urban development – to consider climate change and design quality. This is in order to hit net-zero targets and avoid cookie-cutter housing estates.

Other measures are aimed at ensuring appropriate infrastructure is built to serve these new towns.

There are changes planned too on when orders can be used to buy sites that are broadly to be used for the public good. This could be for affordable homes, health or education facilities, for instance. It would work by reducing payments to the actual value of the land rather than its “hope value” (when landholders hold out for price rises once planning permission is granted).

There is also a commitment to creating a fund, which the government hopes will overcome some of the delays to approving new housing caused by potential threats to wildlife.

The fund will aim to unblock development in general rather than specific sites, as happens at the moment, and will pool contributions from developers to fund nature recovery. Where there are concerns for wildlife, experts will develop a long-term mitigation plan that will be paid for by the fund while allowing the development to go ahead in the meantime.

Will it work?

As a professor of urban and environmental planning, the question for me is will the bill encourage development to progress more speedily? Almost certainly – probably mostly in terms of bringing forward improvements to critical national infrastructure schemes such as the electric grid. For residential development, some incremental speeding up is likely as developers crave certainty in planning decisions.

But on their own, these measures are unlikely to be enough to provide the 1.5 million new homes set out in the government’s target. They offer nothing to tackle critical bottlenecks in terms of both . It is also difficult to see the target being met without much more government involvement – by building social housing in particular.

Will the bill result in better quality development? There is surprisingly little in the plans about improving design quality, other than in areas. This is disappointing, and a missed opportunity to ensure that developers raise their game in residential building and neighbourhood quality.

And might it override local democracy? Arguably yes, but in practice not as much as some critics might argue. Most of the reforms are finessing existing practices, such as delegated powers to planning officers. Much depends on what the national government guidance turns out to be.

The biggest concern is that it might increase invisible political pressures on planning officers by councillors and senior officials. It would have been good to have seen more measures to protect their independence and professional judgement.

Hopefully the bill will speed up delivery of nationally important schemes for critical infrastructure. This means things like modernising the electricity grid and removing repeated use of judicial review to block a development. These elements should create jobs sooner and support economic growth.

Where the bill will make absolutely no difference is in improving living standards for people with older homes. This bill is focused on new builds and has little to offer those hoping for support in retrofitting ageing housing stock with more energy-efficient features or creating green spaces in areas where new development is increasingly in demand.

Despite some of the ministerial bluster about , much of the content of this bill is not about removing planning regulations. It is much more about improving them. Some measures will work better than others, but overall, given the government’s electoral mandate to deliver growth and protect the environment, this is a reasonable balancing act.

It’s unlikely to deliver much growth in its own right, but as an enabler of growth, it is promising. More worrying is whether it will lead to poor-quality housing built at pace and massive scale to inadequate energy-efficiency and design standards. This would fail to deliver on net-zero and biodiversity ambitions. It is very much a minor win for facilitating growth, but for nature it is nothing more than maintaining the status quo.

The new project, POUNDS (Prediction Of UnqualifieD losseS from offshore wind farm wakes), aims to provide a national-scale assessment of interactions between wind farms, supporting policymakers and industry leaders to optimise offshore wind energy production in the drive to net zero.

The UK government has set a target to reach 43-50 GW of offshore wind by 2030. Rapid progress has already been made with 16 GW now in operation and further projects are ongoing development under the recent Contract for Difference Allocations. Nevertheless, achieving the 2030 target requires an up to three-fold increase of capacity, potentially reaching over 100 GW installed capacity by 2050. 

Such substantial expansion of offshore wind farms means they must be built closer together, making it crucial to understand how this affects predictions of annual energy production.

When large groups of turbines are built in close proximity, they create ‘wakes’ where wind slows down behind them. and are increasingly impacting the performance of neighbouring farms, reducing the efficiency of the turbines in producing energy and causing conflicts between wind farm operators.

Project Lead , Research Fellow in the Department of Civil Engineering and Management at �������Թϱ���, said: “Achieving the target of 43-50 GW of deployed offshore wind farms by 2030 is crucial for NetZero and energy security, but reduction in energy prediction due to wind farm wakes must be addressed.”

“Our POUNDS project is key to overcoming these challenges, informing policy makers and project developers about strategies to better quantify these losses. Similar initiatives of national importance have been developed in Germany, The Netherlands and the US, and our project aims to support the whole UK offshore wind industry.”

POUNDS, funded by Engineering and Physical Science Research Council (EPSRC) Supergen Offshore Renewable Energy Impact Hub, will be carried out in partnership with the UK’s leading Offshore Renewable Energy (ORE) institutes, industry experts, and policymakers, including ORE Catapult, Arup, EDF, RWE, and The Crown Estate.

The project’s key aims include:

• Assessing how offshore wind farms affect each other’s energy production, and the revenue implications of these impacts.
• Helping to identify the best locations for future offshore wind farms to minimise these losses and ensure the UK’s renewable energy targets are met.
• Validating modelled performance data against operational data.
• Improving model accuracy in forecasting wind farm energy production.

As for its methodology, POUNDS will use state-of-the-art mesoscale models – a type of advanced numerical weather forecasting model – to model the performance of wind farms spanning UK waters at a resolution of 1 km. It will assess both the wind farms operational in 2023, and the thousands more wind turbines that are planned by 2030.

The analysis will evaluate accuracy of the model relative to real-world data and quantify the effects of inter-farm wakes on predicted energy yield. It will also capture wind-farm wakes and wind-farm performance in comparison to energy export grid data.

This combination of advanced modelling and collaboration with leading stakeholders is designed to support delivery of the UK’s target to become NetZero by 2050.

, Energy Economist with Offshore Renewable Energy Catapult, said: "The UK Government's recent   identification of inter-farm wind wakes as an area of focus highlights this issue's importance. This study could make important contributions towards better understanding and planning around them."

, Wind Skills Leader, UKIMEA, Arup, added: "As the UK continues to expand its offshore wind capacity, balancing the need for security and affordability of supply is becoming increasingly complex. To ensure a just transition, which balances private and public interests, it is critical that we take a collaborative approach to advance our scientific understanding of inter-farm wakes and our ability to quantify the impacts."

By modelling the interactions between wind farms more precisely, the team hopes to provide better guidance for developers and policymakers, reduce investment risks, and resolve conflicts between wind farm operators.

POUNDS could ensure that both the UK’s offshore wind expansion, and 2030 target, remain on track.

The project POUNDS will be officially launched at the , which will be held at �������Թϱ��� on 15th April 2025 and is open to academic colleagues.

Our research is at the forefront of the energy transition. Guided by our innovative spirit and interdisciplinary outlook, we work to mitigate climate change while transforming our energy system, to enable a just and prosperous future for all. Find out more about our energy research. 

The station, part of the UK’s programme, will monitor and provide crucial data on key climate-relevant gases, including carbon dioxide (CO₂), methane (CH₄), and nitrous oxide (N₂O). A new high-precision analyser for monitoring atmospheric hydrogen (H₂) is also being deployed at the site to monitor atmospheric hydrogen (H₂) generated through the growth of the UK’s hydrogen economy.   

The project is a collaboration between �������Թϱ���’s Department of Earth and Environmental Sciences and the Atmospheric Chemistry Research Group at the University of Bristol.

Simon O’Doherty, Professor of Atmospheric Chemistry at the University of Bristol, added: “We can only understand the levels of greenhouse gases in the atmosphere by making continuous high-quality, physical measurements of the atmosphere. The current UK network of monitoring stations set up in 2012 has been a huge success in furthering our understanding, however, the addition of the Jodrell Bank station to the network will enhance our ability to determine emissions in the north-west region of the UK.” 

Data collected from Jodrell Bank will be added to a long-term dataset collected by the UK’s Deriving Emissions linked to Climate Change (DECC) network. These measurements are combined with a computer model that represents the transport of gases from the emission sources to the measurement locations. This enables scientists to estimate the size and location of emissions for each measured gas. The total UK emissions estimated for CH₄ and N₂O using this method are included in the UK’s National Inventory Report that is submitted annually to the United Nations Framework Convention on Climate Change.

As the first site in North West England, the new Jodrell Bank station will provide more granular detail on emissions from Wales and North West England. This will help to improve the accuracy of UK emission estimates and will also permit new studies focused on regional greenhouse gas emissions. Jodrell Bank is also well placed to monitor changes in atmospheric H₂) resulting from planned industrial developments near Ellesmere Port. 

Alistair Manning, Met Office greenhouse gas monitoring Scientific Manager, said: “Jodrell Bank is ideally located to monitor emissions from north Wales and the north-west of England. It complements the existing network perfectly and will enable a better spatial understanding of the emissions of greenhouse gases from these regions. The resulting information will enable the UK to better understand its current emissions and monitor its progress to net zero.” 

The GEMMA Programme is a consortium led by the National Physical Laboratory (NPL), which includes the Met Office, National Centre for Earth Observation, National Centre for Atmospheric Science, University of Bristol, University of �������Թϱ���, and others working together to create a single integrated network to monitor all sources and sinks of greenhouse gases in the UK, funded by NERC and the Building a Green Future Programme. 

Richard Barker, Head of Environment, NPL, said: “With the welcome addition of Jodrell Bank, we can start to provide greater resolution of UK emissions now and also assure the UK network is better suited to the future, more challenging, demands of achieving net zero.”

The researchers stress the importance of combining global efforts to reduce emissions with localised strategies to adapt land management practices and safeguard ecosystems.

The University of Derby’s Dr Kirsten Lees, who is also co-author of the report, added: “Peatland resilience is an important area of research, as these ecosystems store vast amounts of carbon alongside providing a range of other services. Restoration of areas which are in poor condition is key to protecting these carbon stores. Our research shows that future changes in climate are a vital consideration when planning restoration projects, to ensure that work is targeted towards areas where peatlands can thrive.” 

The study argues that these tactics distract from the urgent need to upgrade ageing infrastructure, much of which was built in the 20th century. The companies - 70 per cent of which are owned by foreign investors - have reportedly distributed £76 billion to shareholders since privatisation in 1989, while building up over £56 billion in debt and neglecting vital upgrades.

“These companies have adopted a playbook of denial, deflection, and distraction, similar to other major polluting industries, to protect profits at the expense of the environment and public health” added Professor Alex Ford from the University of Portsmouth. 

The paper calls for stricter regulation of industry communications to combat greenwashing and misinformation, and urges policymakers to prioritise transparency to safeguard water security in the face of climate change. The authors also highlight the need for greater investment in sustainable solutions, such as restoring wetlands, alongside modernising sewerage systems. 

“The financial exploitation of water resources in England raises globally important issues around water security and environmental stewardship,” added Professor Woodward. “There needs to be much more careful scrutiny of water company communications and of the organisations and individuals responsible for environmental management.”

The paper, Water industry strategies to manufacture doubt and deflect blame for sewage pollution in England, is published in Nature Water:

The Bezos Earth Fund - established by Amazon’s founder and former CEO Jeff Bezos in 2020 - is dedicated to supporting efforts that combat climate change and protect nature. With a $10 billion commitment, the fund seeks to drive innovative solutions, catalyse new technologies and promote systemic change to preserve the planet for future generations.

The Bezos Earth Fund announced the $1m Ideation Prize to Accelerate Greenhouse Gas Removal Technology in January 2024, as part of the Fund’s broader Greenhouse Gas Removal initiative. The Prize, as managed by the Experiment Foundation, received more than 700 submissions from around the world. �������Թϱ���'s project ‘ was chosen as one of the 13 winning proposals.

GDI’s team will build on a sustained and world-leading record of environment and development research within the Institute. Most notably, the ongoing project that is exploring the effects of reforestation drivers on both forests and rural poverty, while the recently launched project is interrogating the social risks and benefits of increased use of data in conservation. Members of these project teams have already published impactful research, including a recent Nature Ecology and Evolution assessing the ecological and social impacts of Indigenous territories in Brazil.

Taking place over 3.5 years, the observatory team will combine large-scale geospatial and socioeconomic analyses with in-depth qualitative case studies in Mexico, Brazil and Ghana. A separate stream of work will aim to identify evidence gaps, expanding the thematic and geographical remit of the observatory to regions such as Indonesia or South Africa.

The award will also support Ghana-based researchers exploring the relationship between political settlements and the Just Energy Transition in Africa. Project lead Dr Abdul-Gafaru Abdulai, Associate Professor in the Department of Public Administration at the University of Ghana Business School and Honorary Research Fellow at GDI, explains: “The observatory represents a significant opportunity to develop our understanding the contested forests of Ghana, while strengthening ties between GDI and the University of Ghana. Bringing together big data, which will highlight changes in forest cover, land rights and socioeconomic indicators, together with an in-depth political economy analysis of what is driving these changes will help us to identify and champion approaches that benefit both people and the environment.”

As extreme weather events, such as heatwaves, droughts, floods, and freezes become more common due to global heating, understanding how soil microbes – critical for healthy ecosystems – respond is crucial.

These microbes play a key role in natural processes like carbon cycling, which helps determine how much carbon is stored in the soil and how much is released into the atmosphere as carbon dioxide, a major driver of global heating.

Researchers from �������Թϱ���, working with a network of scientists across Europe, collected soil samples from 30 grasslands in 10 countries. They experimentally exposed the samples to simulated extreme weather events under controlled laboratory conditions to find out how the microbes would respond.

The team found that microbial communities in soils from different parts of Europe each reacted in unique ways to the extreme events. For example, soils from cooler, wetter climates were particularly vulnerable to heatwaves and droughts, while soils from dry regions were more affected by floods.

However, the scientists also found encouraging patterns and signs of consistency. In particular, microbes that can "pause" their activity and go dormant—essentially waiting out tough conditions—in any weather condition.

The findings are published today in the journal .

, Senior Lecturer in Earth and Environment Sciences at �������Թϱ���, said: “Soil microbes are vital for our ecosystems. Their ability to adapt or struggle with climate change has a direct impact on soil health, plant growth, food production and carbon storage.

“By understanding the microbes’ ‘survival strategy’, we can better predict and possibly mitigate future impacts of these extreme weather events, giving us crucial insights to safeguard vulnerable regions.

“But our research highlights just how complex and varied the effects of climate change can be. The fact that local conditions play such a huge role in how vulnerable soils are means that a "one-size-fits-all" approach won’t work when it comes to protecting soil ecosystems, suggesting tailored strategies will be key.”

Each sample site represents the diversity of biogeographic regions present in Europe: alpine (Austria), subarctic (Sweden), Arctic (Iceland), Atlantic (Oxford and Lancaster, UK), boreal (Estonia), continental (Germany), Mediterranean (Spain and GR, Greece) and steppe climate (Russia).

The research offers a key first step in predicting how microbial communities respond to climate extremes, helping inform conservation efforts and climate policies around the world.

, who conducted the research while at �������Թϱ���, now a Professor of Earth Surface Science at the University of Amsterdam, added: “This study is one of the largest of its kind. By working across multiple countries and ecosystems, we have been able to provide key insights that could guide future research and environmental management strategies ensuring the health of our ecosystems in the face of increasing climate challenges.”

Launching in February 2025, the JUST Centre will work closely with communities in five regions of the North of England (West Yorkshire, West Cumbria, Merseyside, Greater �������Թϱ���, and Tyneside) while also generating comparative research in other regions of the UK.  It will collaborate with partners across local, regional, and national government, business, and civil society to co-produce joined-up solutions to meet climate goals while improving citizens’ quality of life.  

It will use an innovative mix of data science and participatory methods to research and map existing low-carbon living initiatives and generate evidence about what works where, why, and for whom. This will enable researchers to support better government decision-making and demonstrate to all people and communities the real improvements in quality of life that are possible if we link decarbonisation with regeneration.

The Centre brings together a team of interdisciplinary social scientists at the Universities of �������Թϱ���, Leeds, Liverpool, Lancaster and Newcastle. The Institute for Community Studies at the not-for-profit organisation is the core partner.

Additional partners are Citizens UK, the Local Government Associations for England and Wales, the Scottish Sustainability Network, the British Chambers of Commerce, the NHS Confederation, the Runnymede Trust and the Institute for Government.

Commenting on the announcement, JUST Centre Director and Principal Investigator, Professor Sherilyn MacGregor said: “To meet the challenge of the climate crisis and the UK’s net zero targets, we need to decarbonise our economy and do so quickly, but without leaving whole regions or communities behind.  ‘Joined-up’ means bridging the gaps between myriad but presently disconnected, evidence-based interventions and policies focused on sustainability and net zero transitions.  

ESRC Executive Chair Stian Westlake said: “Our centres carry out interdisciplinary, cutting-edge research in the social sciences that seeks to change the world for the better. They allow ESRC to make sustained investments in strategically important areas, giving researchers the freedom to research topics in depth.

“The climate crisis is one of the most serious challenges the world faces. To successfully transition to a zero-carbon economy, we need to make sure no one is left behind. The JUST Centre will show us how to include everyone as we transform our country and economy, finding new opportunities and putting power in the hands of local communities.”

Stephen Aldridge, Director, Analysis and Data at the Ministry of Housing, Communities and Local Government (MHCLG), adds: “Net zero poses both huge economic, social, and other challenges and offers no less huge opportunities for the UK - nationally and sub-nationally. To tackle the challenges and seize the opportunities, policymakers and others need evidence – especially evidence on what works and what works most cost-effectively.  

“The Centre for Joined-Up Sustainability Transformations (JUST) is precisely the institutional innovation we need and one I, my team and my department will work closely with across all policy areas. I look forward immensely to engaging with the Centre.”

Professor Paul Monks FRMetS, FRSC, FInstP, Chief Scientific Adviser, Department for Energy Security and Net Zero (DESNZ) said: “Achieving net zero by 2050 requires a wide-reaching transformation of the UK economy and offers an incredible opportunity for jobs, secure energy and growth all across the country. It will improve our health, our quality of life and our overall prosperity. We must support and empower people to participate in the transition. I welcome the establishment of this research centre and its work to ensure a fair, inclusive pathway to net zero.” 

An alarming level of microplastic fragments were found to be present throughout the intertidal mudflat sediments within the Medina Estuary, a Site of Special Scientific Interest (SSSI).  

Microplastics are particles which measure less than five millimetres, and exist in an array of shapes and forms. They cause pollution by entering natural ecosystems from a variety of sources, including run-off from land-based sources and wastewater discharge from Combined Sewer Overflows (CSOs).  

Liberty Turrell, who works as a volunteer for the Hampshire & Isle of Wight Wildlife Trust, collected mudflat sediment from 16 sample sites during low tides for her BA (Hons) Geography dissertation. Analysis of the mud under laboratory conditions discovered three different microplastic shapes: fibres, fragments and beads. Microfibre was the most frequent occurring microplastic shape (99% of all microplastics were microfibres) occurring at all 16 sites.  

Microplastics pollution occurs in estuarine sediments around the world - however, the results from the Isle of Wight are particularly alarming. For comparison, the median value of microplastic concentrations found in the Medina Estuary exceeds the values of estuaries studied in China and India by more than two-fold. 

Jamie Marsh, director of nature recovery (Wilder Wight, Solent & Seas) at Hampshire & Isle of Wight Wildlife Trust said: “The estuary’s mudflats are of significant ecological importance. They support a diverse variety of wildlife providing habitats and breeding areas for a huge array of species including wading birds, crustacea, invertebrates and fish, all of which thrive within the Medina’s intertidal mudflats.  

“The discovery of the high level of microplastics, and of microfibres in particular, in this precious environment is truly staggering. Microfibres cause a significant risk to wildlife as they can easily bundle together. The entangled fibres form a clump and pose a great threat to marine species as the bundles act in the same way as larger plastic items by blocking feeding passageways in the gastrointestinal tract. This can obstruct the movement of food, disrupt the digestive process and cause eventual death.” 

The study also reveals that wastewater discharge from two CSOs with high annual spill rates is a major source of microplastic release into the aquatic environment, and are likely responsible for the immense quantities of fibres reported throughout the Medina Estuary. Dodnor Lane and Fairlee CSO’s together discharged wastewater into the upper estuary for 2,932 hours in 2023 (over 225 total spill events) according to Event Duration Monitoring datasets published by the Environment Agency.  

Professor of Physical Geography said: “Research at the University of �������Թϱ��� has shown that the microplastic contamination of riverbeds is a clear signal that wastewater treatment is not taking place as it should. Effective treatment can remove up to 95% of the microplastic load in wastewater.  

“Microplastic contamination of the Medina Estuary is a concern because it is an area of ecological importance. The Medina Estuary receives high volumes of untreated wastewater from Southern Water assets and the presence of primary microplastic particles provides a clear link to the wastewater system."

"This research helps to resolve a global critical gap in the current studies of microplastics in estuaries," said report author Liberty Turrell. “Unfortunately, the results are shocking. The severe contamination of estuarine environments affected by wastewater discharge takes place across the world and sadly this includes the Isle of Wight. The results clearly show that the prevalence and abundance of microplastics found in the intertidal mudflat sediments highlights a severe contamination issue of the Medina Estuary.”

According to data published by the Environment Agency (2024), there were 464,056 monitored ‘spill’ events into waterways by water companies in England during 2023, a 54% increase from 2022. The 29,494 spills into waterways in Kent, Sussex, Hampshire and the Isle of Wight by Southern Water lasted a total duration of 317,285 hours (Environment Agency, 2024). Spill events are responsible for the release of huge quantities of microplastics into our waterways. 

The ‘Zero Carbon Without a Net’ initiative is part of the University’s Environmental Sustainability strategy which was launched last July, and subsequently won the 2023 . Now, the University is being honoured for its dedication to sustainability on an international scale.

The awards featured 95 finalists from 28 countries, with the University coming first in the ‘’ category, which focuses on assessing the steps that institutions are taking - or are planning to take - to reach their sustainability targets.

Recognising the innovative and pioneering initiatives in sustainability, the celebrate the projects undertaken by further and higher education institutions who are striving for a sustainable future.

The University’s initiative focuses on decarbonising its operations to secure a zero-carbon future by 2038. Progress already made includes:

• The landmark deal signed in May 2024 that will see up to 65% of the University’s electricity demand supplied through a brand-new renewables project.
• Completion of the first phase of building decarbonisation projects including the newly refurbished building which now has the infrastructure to support zero emissions.
• A further £25m pledged to decarbonise the University, taking the zero-carbon budget to £175m.

The Green Gown Award judges commented: “�������Թϱ���’s “Zero Carbon Without a Net” initiative is candid and ambitious. The approach of clearly assessing reality in relation to ambitions is very important and ensures that the approach taken is sincere, going beyond intentions to focus on transformation. Its scientific approach, detailed planning. And substantial internal funding demonstrates a deep institutional commitment to sustainability.”

�������Թϱ���’s Environmental Sustainability strategy builds on the University’s core goals of Teaching and Learning, Research and Discovery and Social Responsibility and stresses the need to embed sustainable practises into all University plans, policies and processes.

The strategy also highlights six priority operational areas, all linking back to the United Nations Sustainability Goals: Construction and Refurbishment; Risk and Climate Resilience; Responsible Procurement; Resource Management; Valuing Nature; Travel and Transport. 

“We are incredibly delighted to be recognised internationally for our decarbonisation plans, which are firmly grounded in science, with our zero-carbon target set in collaboration with experts from the Tyndall Centre for Climate Change Research” said Julia Durkan, �������Թϱ���’s Head of Environmental Sustainability. “This award not only acknowledges our ambitious plans but also celebrates the collective efforts of our colleagues who have made this initiative a reality.  We’re proud to be part of the international effort to tackle climate change, and we know achieving these goals requires continuous, urgent action and global collaboration.”

City of Trees is an independent charity that plant, look after and promote a culture of trees across Greater �������Թϱ���. They work with volunteers across the region, as part of their ‘Citizen Forester’ programme to enhance green skills, boost health and wellbeing, and to help tackle the climate and biodiversity emergency.

Aligned closely with the University’s values and social responsibility agenda, both City of Trees and �������Թϱ��� are passionate about making the region even better, one tree at a time.

In the University's special bicentenary year, it is partnering with City of Trees on several initiatives:

• The University's International Relations team signed the first agreement City of Trees earlier this year, kicking off the partnership which has been growing throughout the bicentenary year. The new agreement and initiative is a positive step in looking at the small changes with big impact that we can make as an institution
• The new agreement and initiative was officially launched at the International Friends of �������Թϱ��� Day on 10 October, whereby the University made a donation on behalf of each international delegate to City of Trees. City of Trees will then plant a tree in Greater �������Թϱ��� to represent each international delegate who attended the event - signifying that international colleagues continue to be a crucial part of the growth and development of both the University and the city.
• For our 200th year specifically, the University is working with City of Trees to plant 200 trees across new woodland sites in Greater �������Թϱ���.
• From 7-9 October the University hosted the THE World Academic Summit and chose to make a charitable donation to City of Trees on behalf of each delegate attending, to the total of £1,500.

�������Թϱ��� is truly excited to be supporting City of Trees and partnering with them on these activities, which will foster into the future.

Mining has a very bad reputation. It is often assumed to be one of the worse land uses – destroying and polluting the environment and creating barren, moon-like landscapes. Where mining occurs in areas of high biodiversity, it is considered a serious threat.

But in the eastern rainforests of Madagascar, over 10,000 people mining for sapphires didn’t cause more damage to the forest than farmers clearing land for agriculture, which remains the most important driver of deforestation in this area.

focuses on quantifying the effects of sapphire mining on the forests of Madagascar. My discoveries challenge some of the preconceptions about the impacts of small-scale mining. I show that, despite being attention-grabbing, some forms of mining can be surprisingly low-impact and less damaging than other land uses.

In October 2016, a valuable deposit of sapphires was discovered by people searching for gold within the protected rainforests of the Ankeniheny-Zahamena corridor in eastern Madagascar. These rainforests are really important for biodiversity as they are home to many unique species , including lemurs such as the indri and black and white ruffed lemur. Word of the sapphire discovery quickly spread. Within weeks from across the island were illegally mining in the Bemainty valley deep within the forest.

Miners used shovels to dig pits between 1m and 3m deep in the valley floor to extract river sediments. They used handmade sieves and water from the stream to sieve the sediment and search for gems. The work was hard, living conditions in the hastily constructed settlements were poor, and the rewards were uncertain.

Unlucky miners left the site poorer than they arrived. Some struck it rich, while others made enough money to survive and perhaps save a little extra to invest in education, land or businesses. This type of mining, termed artisanal and small-scale mining, is not unique to Madagascar. It is widespread, supporting an estimated people around the world.

The mining rush at Bemainty attracted international media attention due to fears over its environmental impacts, with it was causing substantial deforestation and threatening endangered lemur populations. This caused amongst conservationists.

aimed to evaluate the deforestation claims. To properly assess the impact of something, an essential step is to estimate what would have happened without it: the counterfactual. To roughly calculate how much deforestation would have happened at Bemainty without mining, my colleagues and I used the average area of deforestation within a set of control forest areas, chosen to be as similar as possible to Bemainty but crucially, without mining. We then compared deforestation at Bemainty to this counterfactual.

We found that mining at Bemainty did not cause more deforestation than we estimate would have happened anyway from other causes. In this area, the biggest driver of deforestation is shifting agriculture, where people cut and burn patches of forest on slopes to grow rice for a few years in a rotational cycle. We showed that more than 10,000 people mining in the area did not cause more deforestation than several hundred people clearing forest for farming. The impacts of the artisanal gem rush need to be considered within this broader context.

Limited negative effects of mining on deforestation at Bemainty could be for several reasons. First, the sapphires were found within river sediments, confining mining to the valley floor.

Second, much of this area had been cleared for farming decades before when the first settlers arrived. Third, the miners did not use heavy machinery, and sapphire mining does not use toxic chemicals (like the ).

The variability of small-scale mining

More broadly, these results highlight that the environmental impacts of artisanal mining are very variable. They depend on the scale, methods, machinery and chemicals used, and the environmental impact of alternative land uses that people might be doing otherwise, like farming or cutting down trees to make charcoal. Although in some places artisanal and small-scale mining is causing major environmental problems, where mining is small-scale and doesn’t use heavy machinery or chemicals, environmental effects may be similarly limited.

However, in many countries this variability is not considered in policies towards artisanal mining. Policies tend to or otherwise stopping artisanal mining, but often have . I believe that these one-size-fits-all policies are strongly influenced by negative preconceptions about mining and the worst case scenarios, and not necessarily specific evidence, which is lacking for many countries.

Treating all mining as the same needs to stop. Artisanal mining provides income for millions of poor people around the world who, despite the challenges, decide it is their best – and perhaps only – option. Given its importance, policymakers need to rethink their preconceptions. Where mining has a low environmental impact, more open-minded, flexible policies are needed to regulate it in a way which balances the needs of poor communities with biodiversity conservation.

The ‘Bee Cup’ scheme is a joint project between the University, �������Թϱ��� City Council and which will see the implementation of a reusable cup scheme across campus.

Several café locations will be involved in this scheme – including the Student’s Union, Benugo and numerous locations on Oxford Road, such as the Royal Northern College of Music, Eighth Day and Bold Street.

To take part in this initiative, staff and students need to download the app; at UniCafés only, customers will receive their first Bee Cup drink for free. After finishing their drink, customers must return their Bee Cup to one of the participating locations where it will be scanned into the app, washed, stored and reused.

Customers will incur a £5 charge if their cup is not returned within 14 days. The price of disposable cups will increase from 20p to 50p to encourage customers to take part in the Bee Cup initiative.

Thousands of single-use cups are bought, used and discarded across multiple campus café locations every year. Though many of these cups are considered compostable, they cannot be recycled easily and are instead disposed of as general waste.

Sophie Jones, Community Engagement Lead, said: “In Our Nature is a partnership programme dedicated to supporting communities and individuals across �������Թϱ��� to connect the climate crisis with practical actions we can all take to reduce carbon, save money and learn new skills.

“We’re delighted to be supporting the Bee Cup returnable cup scheme as part of our Community Support offer; helping to reduce waste and enable individuals to make more sustainable choices every day.”

The Bee Cup scheme was developed as part of the University’s Environmental Sustainability Strategy launched in 2023. The strategy outlined a plan to reduce the University’s carbon footprint, promote sustainability in teaching, learning, research and innovation, and reduce its negative environmental operational impact.

Alison Shedlock, Director of Campus Services, said: “We are so excited to be launching the Bee Cup and working with partners in the city. I hope that the university community embraces the scheme so that we can significantly reduce the number of single use cups purchased on campus and reduce our carbon footprint, with the objective to expand the scheme across �������Թϱ���.”

With most volcanic activity taking place underground unobserved, for the first time scientists have been able to capture vesiculation kinetics in basaltic magmas in real time. Published today in , the study sheds new light on one of nature’s most astonishing phenomena.

Volcanic eruptions differ drastically, ranging from gentle effusive lava flows to highly explosive events - or sometimes switching between the two at a moment’s notice.

At the worst end of the scale, volcanic eruptions eject massive volumes of magma and volcanic gases into the air. This causes catastrophic local damage and often prompts wide-reaching global effects too, like air traffic space closure and changes in weather patterns.

Scientists highlighted that eruptive style is influenced by how gas dissolved in magma is released. Contrasts can be drawn between how a waiter opens a bottle of champagne in a restaurant, and how champagne pops when shaken by Grand Prix winners. Despite both bottles having the same amount of gas, the champagne leaves the bottles at vastly different speeds.

Volcanic eruption styles depend on how easily magma decouples from gas during ascent, with stronger gas-melt coupling leading to more explosive reactions. This study allowed scientists to observe and quantify real-time bubble growth and coalescence in magma as it reaches the surface.

The pressure vessel used in the laboratory experiments was thick enough to contain vast amounts of stored energy, and X-rays (the I12-JEEP synchrotron beamline from Diamond Light Source) were used to see through the magma sample and make the observations.

, Research Associate in the Department of Earth and Environmental Sciences at �������Թϱ��� and lead author of the study, commented: “The experimental results obtained in this study through the combination of our novel vessel apparatus and X-ray synchrotron radiography, offer an improved understanding of coupling and decoupling between magma and volatiles during ascent in the conduit. This study provides insights into processes leading to eruptive style transitions and, ultimately, has fundamental implications for hazard assessment and risk mitigation in area of active basaltic volcanism.”

Pressure in the chambers could be increased or decreased in a controlled way, allowing scientists to see how expanding bubble walls are broken during coalescence at different pressures and temperatures, from 10km in the magmatic plumbing system right up to the conduit beneath a volcano.

The study is a result of a NERC-NFS large grant awarded to �������Թϱ���, in addition to the universities of Bristol, Durham, Cambridge and Arizona State in the USA. A UKRI FLF project grant was also awarded to �������Թϱ���, and the study was completed in collaboration with colleagues at ESRF in Grenoble, France who developed the novel experimental pressure vessel with windows used in the study.

The growth rates sourced from this new technique confirm previous estimations that used numerical and theoretical modelling. This study contributes to a better understanding of magma behaviour and will greatly improve knowledge of volcanic processes, in addition to helping with future hazard assessment and risk mitigation in areas of active volcanic activity.

The study, published in by scientists at �������Թϱ��� and led by the National Oceanography Centre (NOC), has found that currents sped up, slowed down, changed direction, and sometimes reversed direction completely, depending on the varying and uneven surfaces and features found on the ocean floor.

Previous models suggested that these currents would be continuous and steady. These findings will help scientists to understand the deep-sea pathways of nutrients that sustain deep-sea ecosystems, as well as assessing where microplastics and other pollutants accumulate in the ocean.

By better understanding how deep-sea currents interact with the seafloor, scientists can now more accurately interpret the deposits they leave behind. Those deposits act as long-term recorders of past climate change and can provide important clues about the potential impacts of future ocean changes. 

The seafloor is the final destination for particles such as sand, mud, organic carbon that provides food for seafloor organisms, and even pollutants. Accumulations of these particles in the deep sea are used to reconstruct past climates, natural hazards and ocean conditions. This provides valuable archives of climate change that extends far beyond historical records.

The lead scientist on the project, Dr Mike Clare of NOC, said: “It is important to understand the behaviour and pathways of currents that operate in the deep sea, to determine pathways of natural and human-made particles. This information helps identify where pollution is coming from, which ecosystems it will interact with, and how to make sense of the records preserved in deposits.

“However, there have been very few direct measurements made of currents that flow across the seafloor in deep waters. Most are made high above the seafloor, over short timescales, and only at individual locations. Until now we have not understood how dynamic seafloor currents can be in the deep sea.”

The new study, which involved researchers from the UK, Canada, Germany and Italy, analysed data from an extensive array of sensors to determine the variability in seafloor currents over four years. Thirty-four deep sea moorings were deployed in up to 2.5 km water depths, equipped with high-frequency Acoustic Doppler Current Profilers - likened to an underwater speed camera that measures seafloor currents.

The study’s lead author, Dr Lewis Bailey, formerly of NOC and now at University of Calgary, said “The ocean bottom currents offshore Mozambique are far more variable than we expected. Just like currents in the upper ocean, their intensity changes between seasons and can even flip backwards and forwards over the course of several hours.”

from �������Թϱ���, and a co-author of the study, added: “Seeing how these currents behave is a bit like observing the weather in �������Թϱ��� - always changing and often surprising. But observing change in the deep sea is really challenging and, until now, we have had a poor understanding of what background conditions are like in the deep-sea.”

Professor Elda Miramontes from the University of Bremen, also a co-author of the study, said: “These are the first measurements of deep-sea currents across such a large area, long duration and so close to the seafloor. This makes them extremely valuable as they will help improve our models for reconstructing past changes related to climate change in the ocean.”

Dr Mike Clare of NOC, added: “The deep sea can be extremely dynamic and this study underlines the importance of sustained observations, which provide critical information on understanding the ocean. More detailed observations are critical for understanding the important role bottom currents play in transporting sediment, carbon and pollutants across our planet.”

The full study “Highly variable deep-sea currents over tidal and seasonal timescales” was published in Nature Geoscience: .

“We’ve been working to restore the moorlands of the Peak District and South Pennines for the last 21 years,” said Tom Spencer, Senior Research and Monitoring Officer at Moors for the Future Partnership. “This restoration work is based on scientific evidence and the research with �������Թϱ��� and the University of Newcastle shows the natural flood management benefits of planting sphagnum and the opportunities for upscaling to extend these benefits, especially considering the increased risk of extreme weather events.”

"This study is exciting because it shows that small changes over large areas really can stack up to make a big difference,” said Newcastle University’s Dave Milledge, who also worked on the study. “It also demonstrates that it is possible to make changes that are good for carbon storage, for ecosystems and for people downstream, as well as showing that changes in the hills can make a difference further downstream. But we need to remember that different places and different interventions will behave differently - not all peatland restoration will deliver flood risk benefit, nor should it be expected to."

“These findings are very promising in terms of the potential flood risk reductions that can be achieved by using upstream Natural Flood Management interventions in the peatland headwaters of the catchment,” said David Brown from the Environment Agency. “Utilising detailed plot-scale observations and upscaling using the modelling approach has demonstrated what could be possible - the trick now is to continue with the upland restoration.”

Matthias Honegger, Senior Research Associate at Perspectives Climate Research, said: “No matter your preference on the long-term role – if any – of SRM in managing threats of climate change to human lives and nature, ignoring the topic will not resolve anything. Cautious and deliberate guidance and collaboration on SRM research and its governance are key.”

Julie Vinders, Senior Research Analyst at Trilateral Research, added: “The Co-CREATE project takes a neutral stance on Solar Radiation Management (SRM) and rather focuses on defining the conditions for responsible research. This research is crucial to facilitate informed discussions about SRM and prevent hasty or unilateral deployment of a technology that is not fully understood.”

Dr Peter Irvine, Lecturer at University College London, summarised the project: "Solar Radiation Modification covers a range of different interventions, each with their own potentials, limits, and risks. The Co-Create project will bring together a scientific and technical understanding of these details, with an interdisciplinary assessment of the issues, and stakeholder perspectives to develop robust principles and guidelines for SRM research governance."

The Nile is one of the longest rivers globally and spreads over 11 countries in East Africa, supplying water, energy production, environmental quality and cultural wealth. However, the use of Nile resources has been a long-standing source of tension, often overshadowing opportunities for cooperation and mutual benefit.

But as the demand for energy, water, and food in Africa is steadily increasing, the study, led by �������Թϱ��� in collaboration with regional organisations, offers a glimmer of hope at a resolution.

The research, published today in the journal , moves away from traditional water-centric agreements, and presents a detailed simulation of the combined energy-water system to reveal how different scenarios of international energy trades could help alleviate the Nile water conflict.

First author Dr Mikiyas Etichia from �������Թϱ���, said: “Traditionally, water disputes in transboundary river basins like the Nile have been approached through a water-centric viewpoint. However, sharing benefits of water resources, such as hydro-generated electricity, crops and fisheries can result in a win-win situation.”

Co-author Dr Mohammed Basheer, Assistant Professor at the University of Toronto, added: “In the Nile Basin, energy-river basin benefit-sharing projects have been implemented in the past at a small scale, but detailed tools like the one presented in the paper can help create actionable large-scale proposals.”

At the heart of the dispute lies the Grand Ethiopian Renaissance Dam (GERD) - a large dam on the Blue Nile River in Ethiopia constructed to improve Ethiopia's electricity access and to export electricity to neighbouring countries. The project sparked tensions between Ethiopia, Sudan and Egypt over water rights and access.

The simulator, designed by the scientists using open-source technology, covers 13 East African countries, including those within the Nile Basin, to model potential energy trade agreements between Ethiopia, Sudan, and Egypt.

By increasing electricity trade, countries can simultaneously address water deficits, boost hydropower generation, reduce energy curtailment, and cut greenhouse gas emissions.

Corresponding author from �������Թϱ���, said: “The energy trades tested in this study provide the countries a range of solutions that are likely in their national interest.

“The study highlights the value of detailed multisector simulation to unpick the complex interdependencies of large multi-country resource systems. Implementation of the arrangements proposed here would need to be further assessed from governance and legal perspectives to become viable proposals. If successful, they could contribute to sustainable resource management and regional stability.

“We are hopeful the new analytical tools or their results will be taken up by the negotiating parties.”

Mountain ranges covering vast areas of the world are warming much faster than surrounding lowland areas, triggering huge reductions in snow cover and rapid upward movement of dwarf-shrubs, such as heather.

Scientists at �������Թϱ��� have found that these changes are disrupting the timing of crucial alpine ecosystem functions performed by plants and soil microorganisms.

The research, published today in the journal and funded by the UK Natural Environment Research Council, shows that high mountain ecosystems may be less capable of retaining the important nutrients needed to sustain plant growth and maintain biodiversity in these harsh environments.

Every year, seasonal changes in mountain ecosystems prompt large transfers of nutrients between plants and microbial communities in alpine soils. Following snowmelt in spring, plants start to grow and compete with soil microbes for nutrients, thereby triggering a shift in the storage of nutrients from soil to plants. This transfer is reversed in autumn, as plants die back, and nutrients are returned to the soil within dead leaves and roots.

During alpine winters, snow acts like an insulating blanket that allows soil microbes to continue functioning and store nutrients in their biomass and enables plants to survive cold alpine winters. Climate change is predicted to cause an 80-90% loss of snow cover by the end of the century in parts of the European Alps and advance the timing of snowmelt by five to 10 weeks.

Prof Michael Bahn, a collaborator on the project from the University of Innsbruck, said: "Declining winter snow cover is one of the most obvious and pronounced impacts of climate change in the Alps. Its effects on the functioning and biodiversity of alpine ecosystems are a major concern for people living in Alpine regions and beyond.”

The scientists from �������Թϱ���, in collaboration with the University of Innsbruck, Helmholtz Zentrum München, and the UK Centre for Ecology and Hydrology, carried out the work on a long-term field experiment in the European Alps. The findings highlight the detrimental effect of climate change on seasonal transfers and retention of nutrients between plants and soil microbes.

For scientists, understanding how ecosystems respond to multiple simultaneous climate change impacts remains a major challenge. Interactions between direct and indirect climate change factors, such as snow cover change or less obvious ones such as dwarf-shrub expansion, can lead to sudden and unexpected changes in ecosystem functioning. These effects are impossible to predict by studying climate change factors in isolation.

Mr Khan, who has represented �������Թϱ��� Gorton in Parliament since 2017, also toured the �������Թϱ��� Air Quality Supersite – one of the largest locations in the UK dedicated to air quality research – and took part in a roundtable discussion with senior academics.

Supported by the University’s endowment fund, the Firs upgrade delivered state-of the-art greenhouse facilities that support expert research on food security and climate change. They comprise 14 climate controlled growing compartments which simulate an assortment of different growing environments around the world ranging from tropical to sub-arctic.

The �������Թϱ��� Air Quality Supersite, also located on the University’s Fallowfield campus, is home to a mobile research laboratory that gathers detailed data on the contents of harmful urban air pollution.  It is one of three air quality supersites across the UK established as part of a £6 million investment by the Natural Environment Research Council. 

Mr Khan was welcomed by , Professor , Professor and Dr Oliver Hughes, who all joined the roundtable discussion.

Professor Coe, a Professor of Atmospheric Composition and Director of the �������Թϱ��� Environmental Research Institute, said: “It was a pleasure to meet Mr Khan and lead the tour of the �������Թϱ��� Air Quality Supersite which has the capability to work out where the gases and particles that pollute our air are coming from and how they form.

“We are immensely proud of the role �������Թϱ��� plays in this area of academic research and the potential this work has to reduce air pollution on a global scale.”

Professor Cruickshank, a Professor in Biomedical Sciences and Public Engagement, recently published an on the Policy@ �������Թϱ��� website addressing how better community engagement can encourage more people to use modes of ‘active transport’ – such as walking and cycling - and reduce air pollution in high risk areas.  

She said: “My colleagues and I regularly engage with policymakers.  Having an opportunity to brief Mr Khan on our ongoing activities and exchange ideas was a useful part of this process.

“My article, published by Policy@ �������Թϱ���, highlights the way that involving and empowering communities can identify key priorities to tackle pollution in neighbourhoods to enhance their lives.

“Greater �������Թϱ��� has among the worst levels of pollution in the UK, with poor air quality estimated to contribute to around 1,200 premature deaths each year in the city region.

“That is a shocking statistic which underscores how important it is to involve local communities in the drive to reduce the impacts of air pollution.” 

Afzal Khan MP said: “It was a privilege to visit the Firs Environmental Research Station and the �������Թϱ��� Air Quality Supersite which are shining beacons in climate change and air quality research.

“My roundtable meeting also provided a fascinating insight into the many research activities taking place on-site.

“We face huge global climate challenges, and it is heartening to see the work going on here in �������Թϱ��� to formulate evidence-based solutions to help address them.       

“I thank the University’s policy engagement unit, Policy@ �������Թϱ���, for putting such an interesting programme together.”

The scheme close to Kale Street will help combat the area’s disproportionate exposure to air pollution, improve the health and wellbeing of local people and improve public safety away from major roads.

Nine signs  put up along the various entry points to the attractive 15 minute walk  will contain digitally interactive QR codes, which when scanned with a smartphone will direct the public to various webpages.

The pages contain information about local ecology and how plant species support �������Թϱ���'s biodiversity.

They also details the history of the site and the local community groups that manage it.

Daniell Musaheb, Ardwick Climate Action said: “Green Routes represent community action directly tackling our community’s issues, with a need to address air pollution and public safety at its core.

“We are honoured at the support the project has received from our partners which has undeniably contributed to its success.

“We hope to see further tangible outcomes for our community and that this is the first step in realising a fairer balance in �������Թϱ���.

“Ardwick is disproportionately affected by air pollution, and the public safety of local people is compromised due to the lack of infrastructure to support green transportation.”

To  celebrate the launch, the group are organising lavender planting. Representatives from a range of groups including Clean Cities, Friends of the Earth �������Թϱ���, Asthma and Lung UK, Mums for Lungs and Living Streets UK will talk about air pollution, road safety and green routes in �������Թϱ���.

And a guided walk from the A6 will show participants  why the Green Route is so badly needed.

Since 2022, ACA has conducted in partnership with �������Թϱ��� which showed that local communities are an important way understand where local sources of pollution are and barriers to less polluting forms of travel.

One of the researchers, said: “Collaborative working between local communities and our researchers was vital to understand the barriers for active travel and the issues that most impacted residents.

“By engaging with communities we can promote awareness of the risks of pollution to health and do more meaningful research that best meets the needs of those most impacted by pollution.

She added: “This research highlighted real issues encountered by residents of high levels of pollution and dangerous roads with fast moving traffic.

“There is a lack of crossings across busy roads which makes it very hard for residents to get around safely.

“We are so excited about the green route and we really hope it makes a difference to residents for their health and wellbeing as they can avoid some of the traffic and pollution and enjoy the incredible biodiversity created by the planting done by ACA.”

🌳 Trees can make farms more sustainable – here’s how to help farmers plant more.

— �������Թϱ��� (@OfficialUoM)

Written by , Postgraduate Researcher,

Imagine making one change to a farm field so that as well as producing food, it also generated building materials, fuel and fodder. At the same time, this change would nourish the health of the soil, regulate the micro-climate and support pest-controlling wildlife. In fact, it could even produce a whole other crop.

All these things could be possible by simply planting trees amid crops – and not just trees, but also shrubs, palms and bamboo.

This approach to farming is known as agroforestry, and it could improve the sustainability of agriculture worldwide. On a large scale, it could help mitigate climate change by in land that can still serve other purposes. Countries can even towards their reforestation commitments.

There is for planting trees on farms in south Asia and sub-Saharan Africa. But a lot of these plots – on average, less than 2 hectares (or two football fields). Any use of space has to really earn it.

So, how do we ensure trees work for farmers and the planet? India, where the last two decades have seen phenomenal changes in agroforestry, offers some insight.

India’s agroforestry experiment

India’s first effort to get more trees on farms started in 1999 with the Lok Vaniki scheme in Madhya Pradesh, a state in central India. The state government started the scheme to help farmers with degraded land secure additional income from timber and provided them with saplings of teak.

The scheme had a troubled start. The Indian supreme court had banned all tree felling except that permitted under the forest working plan three years earlier. Before farmers could sell the timber they grew, their request to fell the tree would need to be approved by the government.

Farmers were apprehensive about planting something they may not get permission to harvest, and teak trees take 20 years to yield timber. A cumbersome process for obtaining permits and high transport costs for small and marginal farmers scuppered the scheme.

The state responded by exempting certain trees from felling regulations. By 2014, India had a national agroforestry policy that offered farmers saplings and simpler procedures for harvesting and transporting trees. Still, the tree cover on farms didn’t budge. In fact, the last decade has seen in trees on farms in India, according to a study I contributed to.

The decline was pronounced among mature trees. Once these gnarled veterans had shaded open wells on farms and kept water from evaporating in the sun’s glare. Now deeper bore wells could be dug, rendering such trees obsolete.

The expansion of mechanised farming put a premium on treeless fields where tractors and farm vehicles could easily manoeuvre. Attacks by fungal parasites claimed other trees.

Some farmers were unsentimental. In interviews, many said they saw few benefits from trees, which could prevent sunlight from reaching crops. But the decline of native trees on farms like neem, mahua and jamun, once prized for their medicinal oils and nutritious fruit, , particularly in the poorest regions.

Trees on farms, not tree farms

While farmland trees dwindled across India, . These are essentially farms growing .

These plantations largely comprise exotic and fast-growing trees like eucalyptus, poplar and casuarina, which are all exempt from felling regulations. Enticed by the prospect of generating carbon credits on the international carbon market, and by demand for pulpwood for making paper, farmers with some of the smallest plots in India tried switching their crops to block plantations.

When the price of carbon credits dropped with the of the UN’s clean development mechanism in 2012, these small farmers were left with little to show for it. later confirmed that many would have been better off keeping their land for agriculture.

Although there is for pulpwood and timber in India, it is likely to favour farmers who can plant in large areas, cover harvest and transit costs, and wait for returns from plantations – a situation small and marginal farmers can ill afford.

These exotic plantations are either. For instance, eucalyptus consumes a lot of water and soil nutrients, leaving the land less fertile for future cultivation. Its leaves and flowers are less useful to birds than many native trees.

There is a rush globally to plant more trees on farms without considering what farmers will do with the tree in 20 years, or how it may interfere with crop production. This problem is not unique to India and has been noted elsewhere, .

Trees should still be encouraged on farms; preferably native trees that are beneficial for local diets and medicine. So far, though, the trend in India and elsewhere has been towards block plantations of exotic trees – a phenomenon largely driven by the lure of carbon credits.

The focus should be on supporting small and marginal farmers to grow native trees sustainably. Scattered trees of many species on small farms have bigger benefits for farmers and the environment than single-species plantations.

For that to happen, though, there has to be some way of financing this process. If carbon credit mechanisms can recognise this model of agroforestry and help small farmers add trees to their cropland, it would be a big shift in the right direction.

Atmospheric chemists from the , University of �������Թϱ���, and University of York are working together to quantify the gases and aerosols that come from stoves in people’s homes. 

Wood burners - the biggest sources of small particulate matter nationwide

The popularity of using wood burners has increased in recent years, in response to severe cold snaps and the rising cost of gas and electricity. 

In the UK, wood burning in homes is the main direct source of airborne particulate matter less than 2.5 micrometres in diameter (known as PM2.5), and accounts for a high fraction of particles with carcinogenic potential in urban areas. 

Exposure to PM2.5 particles can result in serious health impacts - especially for elderly people and people with respiratory illnesses. 

Stove in a lab - a scientific test facility to capture wood burner emissions

Scientists are using a state-of-the-art test facility, in a �������Թϱ���-based laboratory, to study emissions from domestic heating stoves. 

By using a wood burner in a controlled environment alongside specialised pollution monitoring equipment, researchers are replicating a range of conditions and real-life scenarios.

Dr Marvin Shaw, research scientist at the National Centre for Atmospheric Science and the University of York, said: “Recent studies of combustion in household woodburners suggest that operational conditions, such as ignition, reloading, maloperation and use of unconventional fuels are a large and unaccounted for source of pollution in the UK. This project brings together national expertise in order to understand how the operation of these wood burners affects the emissions of gas and particulate pollutants.”

The high-resolution data they are collecting will begin to build a detailed insight into real-time emissions during stove operation in people’s homes. 

, a research scientist at the National Centre for Atmospheric Science and �������Թϱ���, explained: “Currently emissions predictions assume that wood burners are operated correctly and the appropriate fuels are used. However, we suspect that many wood burners are not used correctly, with people likely to overstack fuel or burn unseasoned woods. Our laboratory experiments will investigate the effects of gas emissions that condense in the air and form particulate matter after they are emitted." 

The air pollution research project they are working on, known as CondensabLe AeRosol from non Ideal Stove Emissions - CLARISE, brings together expertise in biomass burning experiments, emissions monitoring, atmospheric complexity analysis, and regional modelling.

The initiative, funded by a Defra Air Quality Grant, seeks to understand the motivations behind burning solid fuels in homes and gardens, improve community knowledge and influence behaviour and improve public health in Greater �������Թϱ���.

Smoke from log burners, domestic fires and garden bonfires contain tiny particles called particulate matter (PM2.5) that can damage people’s health, increasing the risk of respiratory conditions, such as asthma, and lead to more serious health conditions. 

The study – led by �������Թϱ��� on behalf of Greater �������Թϱ���’s 10 councils – aims to understand the link between household burning practices (indoor and outdoor) and local air quality.

Over the next two years, the research partnership will help inform a public health campaign across the city region to raise awareness around the negative impacts of domestic burning, with the aim to reduce particulate matter emissions through reduced and cleaner burning habits.

The survey will run until February 2024 and invites both people who burn at home and those that do not to take part.

Those that complete the survey can enter a draw to win one of five food vouchers. The link to the survey can be found

In conjunction with the study, Greater �������Թϱ��� has launched an to educate residents about the health impacts and regulations surrounding domestic burning. Over 40 air quality monitors will be strategically placed across the region to better understand the link between domestic burning and PM2.5 air pollution.

The study is one of many research projects at the University which is looking into the

Residents who do need to burn this winter are being encouraged to follow these guidelines:   

• Find out if you are in a – if so your stove needs to be Defra-exempt and you must only use approved fuel.    
• Only burn clean seasoned wood with a moisture content of less than 20% or dried for a minimum of two years, or use ‘Ready to Burn’ approved manufactured solid fuels.   
• Do not burn rubbish or general waste.   
• Get your chimney swept each year and your stove checked.   
• Do not let your fire smoulder overnight. 

Take part in the survey

Since the third UN climate change summit, held in 1997 in Kyoto, Japan, different mechanisms have been trialled to raise money and help countries reduce deforestation and restore degraded forests. First there was Kyoto’s clean development mechanism, then the UN-REDD programme initiated at COP13 in Bali in 2008. Voluntary carbon market schemes came into effect after COP21 in Paris in 2015, but all met with limited success.

In some cases, these schemes with communities that have tended and nurtured forests for generations, restricting their access to the forest for fuel, grazing and food. Meanwhile, deforestation has proceeded under the aegis of global markets hungry for beef, palm oil .

The world is far off track to reduce deforestation to zero by 2030, or meet its target of restoring over 350 million hectares.

At the current climate talks, COP28 in Dubai, Brazil has proposed a “tropical forests forever fund” with an outlay of US$250 billion, which would to conserve or expand their forests. But how can the world be confident that the result will be different this time?

The work of one academic, Nobel laureate Elinor Ostrom, can tell us why previous efforts to restore forests have failed – and what a more effective approach might look like.

Bundles of rights

Nearly 295 million people in developing countries across Africa, Asia and Latin America live on land that has been identified as . The right to extract timber or plant trees ultimately lies with the state in these places, so it is up to the state to set targets for increasing tree coverage or how much carbon the land stores, regardless of how it affects the .

Over 73% (about 3 billion hectares) of global forested land is . One of the arguments for allowing governments to retain ownership of these forests, including the right to manage them, is the notion of the “tragedy of the commons”: in the absence of an all-powerful governing entity, people will overuse shared resources.

In fact, Ostrom’s work on the commons in forests, fishing grounds and grazing pastures shows that communities tend to protect and sustainably use common resources – provided they have rights, tenure, and the ability to decide rules for managing them.

A recent examined forest commons in 15 tropical countries, where governments own the forest but have allowed local communities informal or customary rights of use and management. The authors noted that these forest commons had a high variety of tree species, and offered enough fodder and fuel wood to sustain livelihoods in the local community. The wealth of biomass in these forests indicated a lot of carbon was also being stored.

These findings seem to affirm that forests used and managed by Indigenous and rural communities can support global objectives for carbon and biodiversity, while meeting the needs of local people.

Ostrom’s research identified five important that allow communities to sustainably manage a parcel of land in such commons. These are: access, withdrawal, management, exclusion, and alienation.

Access and withdrawal rights are the minimum required for communities to go into a forest and collect timber, flowers, leaves and grasses for their subsistence and to sell commercially. The most important of these rights, at least in terms of forest restoration, is management rights, including the right to decide where and what type of trees to plant in order to restore a forest.

But Ostrom found that these rights are worthless unless imbued with secure “” – in other words, confidence that land users would not be arbitrarily deprived of their rights over particular parcels of land.

Attempts by governments to provide partial management rights to local communities in recent decades have when it comes to restoring forests. For example, India has attempted to revive degraded forests since 1991 through its joint forest management programme, which offers partial rights to communities that are invited to help prepare a management plan. But without legally binding rights or secure tenure, this approach has shown .

In contrast, India’s forest rights act 2006, the first of its kind globally, provided local communities that had traditionally used an area of forested land with . The result has been restored forests and communities benefiting from increased sales of bamboo and tendu (leaves for rolling tobacco), .

Empower forest communities

To restore Earth’s forests and mitigate climate change, states should devolve management rights to the communities in these land parcels and grant them secure tenure.

But how should these commons be governed? Ostrom’s many years of research are, again, a useful guide. She for clear boundaries defining the community’s rights, rules for forest use, the rights of all members of a community to participate in making those rules (including women and marginal communities), collective decision-making on managing resources, effective monitoring, graduated sanctions for rule violations, conflict resolution mechanisms, and a nested governance structure when multiple communities have rights over the same resources.

There are clear limitations on Indigenous and forest-dependent communities to access the finance that might aid them in their restoration work. Brazil’s proposed fund, and existing climate finance mechanism such as REDD+ and the green climate fund, must be made accessible to these forest communities. This would be easier if they had secure rights and tenure, with a clear set of management rules.

The Green Gown Awards celebrate the innovative and change making initiatives and projects in sustainability across the further and higher education sectors, and the University of �������Թϱ��� claimed the top prize for work supporting its new Environmental Sustainability strategy, which launched in July 2023.

The judges said that they were “impressed with the honest, forward looking, innovative, transferrable, scalable and holistic approaches involving carbon budgeting to help deliver the University’s Zero Carbon Masterplan with effective ongoing evaluation and realistic assessment of outputs yet to be realised.”

The team collected their award at a ceremony at the Titanic Hotel in Liverpool on Thursday, 30 November.

Professor Dame Nancy Rothwell, President and Vice-Chancellor, said: “Winning the prize is a powerful signal to our community about the seriousness with which we are working to our zero carbon target. Our entry is a great example of academic and professional services staff working together and success would be valuable recognition for them.”

Richard Smith, Head of Environmental Sustainability at �������Թϱ���, added: “We are thrilled that the University has been recognised at this year’s Green Gown Awards.

“We pride ourselves on basing everything we do on what science demands of us. Our target was devised by our colleagues at the Tyndall Centre for Climate Change Research and achieving it requires consistent, urgent action.  

“The work on this initiative has been shared with other HE institutions and city neighbours as we rise to the challenge of climate change together. This award is testament to the hard work and dedication of all our colleagues involved in putting this initiative together and making it come to life.”

So far, the University has secured £157.3m of funding from internal and external sources to deliver its sustainability goals.

It has already begun implementing the strategy with its first air-source heat pumps now in operation, and its first heat pump-only building in construction ready to go live early next year, with much more to come. 

The Environmental Sustainability strategy builds on the University’s core goals of Teaching and Learning, Research and Discovery and Social Responsibility and stresses the need for all decisions to be taken in the light of our existing carbon commitments.

It also highlights six priority operational areas, all linking back to the United Nations Sustainability Goals: Construction and Refurbishment; Risk and Climate Resilience; Responsible Procurement; Resource Management; Valuing Nature; Travel and Transport.

Charlotte Bonner, CEO, EAUC, who deliver the Green Gown Awards, said: “The Green Gown Awards celebrate the most innovative and impactful work being done by those working in the post-16 education sector. The projects, initiatives and people showcased through the awards this year are, as ever, inspirational – it’s been a privilege to be part of the judging. I look forward to seeing them flourish in future and to using their examples to springboard further action for sustainability.”

The 2023 UK & Ireland Awards are held in association with UK Research and Innovation. Now in its 19th year, the 2023 results showcase 20 Winner and 17 Highly Commended institutions.

A new special feature published today (November 21), in the (PNAS), which was guest edited by researchers from �������Թϱ���, the Institute for Ecological Economy Research (IÖW), and Harvard University, presents new findings about transitions in electricity, food and mobility systems.

These findings synthesise, elaborate and apply research on sustainability transitions, which has progressed significantly over the past decade, generating novel insights about the dynamics of transitions. This research shifts the focus from sustainability goals and targets to the real-world change processes that could help to meet those targets. The special feature contains 15 articles that present new insights on transitions to a wider sustainability science audience, policymakers, and practitioners.

Large-scale, long-term changes of systems needed

“The central challenge of our age is how to make development sustainable – to assure that it advances people’s well-being in the here and now without unfairly constraining the ability of people elsewhere, or in the future, to advance their own well-being”, says William Clark, professor at Harvard University and director of its Sustainability Science Program. “That requires transitions, by which we mean significant large-scale, long-term changes in the actors, institutions, technologies, and resources that make up consumption-production systems.” The papers in the special feature analyse these changes for electricity, mobility, and food systems. In addition, they address crosscutting issues such as the destabilisation of existing systems, the role of shocks, and the governance of transitions.

Core aspects of transitions research: multi-level interactions, solutions, process of change

“This special feature makes three contributions to the pursuit of sustainability: highlighting the importance of multi-level interactions in sustainability transitions, a focus on solutions (innovation), and a deeper and more differentiated analysis of the processes of change”, explains , professor of sustainability transitions at �������Թϱ���. “It is interesting to see that transitions in the electricity, mobility and food systems are currently unfolding at different speed and depth. This is due to different techno-economic developments and socio-political activities. They have progressed farthest in the electricity system. In the (auto)mobility system they are beginning to unfold, and in food systems they appear to be in early phases.”

The papers demonstrate the multi-dimensional nature of sustainability transition processes which cannot be reduced to purely technological or economic explanations. Instead, they show the importance of understanding sustainability transitions as multi-level, systemic, incomplete, and contested processes, in which innovation plays an essential role that is always shaped by and contributing to social, political, economic, and cultural developments.

Deeper transitions are slower

“One of the important findings from across the special feature is that transitions are often about reconfiguration rather than substitution of existing systems, and that there are tensions between depth and speed of change: the deeper a change, the more difficult and slower it tends to be. It is also important to recognise that the governance of transitions is highly political and can be very politicised. There are winners and losers”, states Florian Kern, transitions researcher at the Berlin-based Institute for Ecological Economy Research. “While recognising various complexities, the special feature also shows how transition processes can be accelerated and steered in more sustainable directions. This is crucial, because historical transitions were often slow, decade-long processes, while time is pressing for the polycrises of the present.”

Though scientists already know that the warming of our rivers and oceans causes direct physiological stress to fish, this study shows the impact on their developing embryos has a deep-seated effect on their gene expression patterns as adults.

These changes may also affect their capacity to respond to future changes in temperature, having consequences for surviving climate change in their adult life.

Scientists have failed to find consistent differentially expressed genes implicated in biological changes linked to global warming.

However, the University of �������Թϱ��� analysis suggests different phenotypes identified in later life may occur through changes in the organisation of the transcriptome - the genetic code as it is read – one crucial element of life itself.

Their findings, using sophisticated modelling, show that transcriptomes of developmentally warmed fishes are characterised by an increased disorder in the way genes interact, implying a less structured, more ‘random’ set of gene interactions.

Professor Holly Shiels, from �������Թϱ���, said: “Climate change is a major threat facing animals. As the world’s oceans and rivers continue to warm the physiological and population level stresses exerted upon fishes will continue to grow.

“If we are to predict and mitigate the consequences of global warming, it is crucial we understand how it influences an animal’s biological capacity to respond to future environmental challenges.”

Dr Dan Ripley, from �������Թϱ���, said: “Our findings suggest that exposure to elevated temperatures during the development and growth of an embryo may influence the ability of fish to respond to future challenges they face in later life.”

Dr Adam Stevens, from �������Թϱ���, added: “In our study, we found that developmental warming influenced the relationships between genes. The ‘plumbing’ of the system was changed, with knock-on consequences for how it then functions in adulthood.

“This was absent in animals reared under ‘control’ conditions.”

The embryos were held in either control conditions, representing everyday temperatures, or warmer treatment conditions, representing future conditions under climate change.

Following embryogenesis, all fish were moved to control conditions, simulating adult fish in the wild moving to find areas at their preferred temperature.

Despite living in their preferred temperature range as adults, genomic differences were found between the groups related to the temperatures they experienced as embryos.

These differences were associated with an altered capacity to respond to future warming as adults.
