New Study Addresses Nitrogen Accumulation in Soils for Better Environmental Management

Published on by Lisa

 

A TU-Durham University collaboration has yielded a detailed nitrogen budget to assess how nitrogen moves across different land uses in a large, mixed land-use UK catchment. This newly published work highlights the importance of accurately measuring nitrogen (N) accumulation to mitigate its harmful impacts on climate and ecosystems.

The Trent catchment, known for its extensive water quality monitoring, provided a unique opportunity to map nitrogen flows and pinpoint where accumulation occurs. One key finding was the higher nitrogen build-up in grassland subsoils compared to arable land, revealing the complex interactions between land use, nitrogen, and soil health.

Excess nitrogen in soil can lead to water pollution, loss of biodiversity, and increased greenhouse gas emissions, making proper nutrient management essential. This study advances our understanding of nitrogen dynamics, providing valuable information toward sustainable environmental management.

New Study Examines University Students’ Attitudes Toward Single-Use Plastics

Published on by Gillian

The widespread use of single-use plastics (SUP) is a growing environmental issue, particularly in Thailand, where plastic waste poses significant challenges. A recent study by Dr Oluseye Oludoye, focusing on Thai university students, explores the factors influencing their efforts to reduce plastic consumption, offering valuable insights for promoting sustainability. Using the Theory of Planned Behaviour, the research examined how attitudes, perceived control, and social influences affect students’ intentions at different stages of behaviour change.

The findings show that while positive attitudes towards reducing SUP are important, they only encourage action among students already contemplating change. In contrast, students’ belief in their ability to make a difference—perceived behavioural control—proved crucial across all decision-making stages. Social influences also played a key role in shaping initial attitudes, highlighting how peer dynamics can motivate change.

These insights are essential for educators and policymakers aiming to foster sustainable behaviours. Campaigns tailored to different stages of behaviour change can be more effective, and leveraging social influence through student-led initiatives could further encourage action. The study also suggests that reducing SUP might inspire students to adopt other sustainable practices. Overall, this research enhances our understanding of engaging young adults in environmental efforts and paves the way for a more sustainable future.

New research tackles single-use plastics in Thailand

Published on by Gillian

In our ever-evolving world, environmental sustainability has become a crucial topic of discussion. One of the most pressing challenges we face is the issue of single-use plastics (SUP). These materials, while convenient, have become pervasive in daily life, and their environmental impact is significant. In this context, a recent collaborative study shines a light on the pro-environmental behaviour (PB) of Thai communities regarding the reduction of SUP, particularly in food packaging.

Published in Scientific Reports, part of the Nature journal portfolio, the study was led by Oluseye Oludoye from Teesside University in collaboration with partners from Université Catholique de Louvain (Belgium), University of Lagos (Nigeria), Chulalongkorn University (Thailand), and University of California Davis (USA). It examined how residents from rural (Sichang Island) and urban (Nonthaburi city) areas of Thailand approach SUP reduction and what motivates their behaviour.

The study found that morality significantly influenced SUP reduction in both, rural and urban areas, but with an interesting twist. Rural residents were more driven by rational decision-making, while urban residents were motivated by moral values when choosing to reduce their plastic use. These insights are invaluable for policymakers looking to develop targeted sustainability initiatives that resonate with the specific motivations of different communities.

As we continue to face environmental challenges, knowing what motivates people to reduce plastic use can help create better solutions and encourage more sustainable habits in our everyday lives.

Dr Lauren Rawlins

Published on by Gillian

On 24 January 2024, the Earth & Environment Research Group welcomed external speaker, Dr Lauren Rawlins, who recently completed her PhD at the Department of Environment & Geography at the University of York. Lauren presented her PhD research investigating the impacts of climate change on the glaciers of Greenland. Through remote sensing of the Humboldt Glacier in northwest Greenland, Lauren observed significant seasonal surface melting extending 80 kilometres inland from the coast. The formation of pooled water and drainage networks on the glacier’s surface lowers the surface ‘albedo’ (meaning its ability to reflect incoming solar radiation) and contributes to more melting. The surface meltwater can also infiltrate down to the base of the glacier where it can speed up the ice sheet’s advance toward the comparatively warmer coast, leading to further melting. Lauren’s talk also took us down to SW Greenland where she performed uncrewed aerial vehicle (UAV) surveys and some remarkable 3-D mapping of the smaller, Russell glacier, to study the distribution and interactions of surface meltwater with ‘cryoconite’ (dark patches containing algae, black carbon, and other dark coloured particulates that reduce surface albedo).

Lauren’s talk was riveting and, her research, scientifically rigorous. Understanding the sensitivity of the Greenland ice sheet to external factors is critical for predicting future change.

At the end of Lauren’s talk, our own Dr Adrian Dye asked her if she could offer any advice to our PhD and prospective PhD students. Amongst several words of wisdom, Lauren emphasised the importance of having a good rapport with your supervisor, ensuring that the University is a good fit, and, once the PhD project is underway, avoid biting off more than you can chew to avoid burnout.

Lauren’s recent publication can be found here https://tc.copernicus.org/articles/17/4729/2023/tc-17-4729-2023-discussion.html. For members of the research group who missed Lauren’s talk, you can find the recording on the Teams site.

Sustainable Agriculture and Waste Management: A Path Towards Environmental Stewardship

Published on by Gillian

On November 29, 2023, Environmental Research Society led by the MSc students hosted Dr Oluseye Oludoye. He presented on the topic titled “Sustainable Agriculture and Waste Management: A Path Towards Environmental Stewardship”. This presentation delves into the pivotal role of these interconnected practices in shaping environmental sustainability. In the pursuit of a sustainable and resilient future, the intersection of agriculture and waste management emerges as a critical nexus.

In the intricate dance of sustainable agriculture and waste management, individual behaviours become catalysts for change. He stated that our journey begins with understanding the symbiotic relationship between responsible agricultural practices and effective waste management.

Connecting the Dots: Sustainable agriculture is not merely a buzzword but a commitment to cultivating the land while preserving its essence. For instance, Dr Oluseye Oludoye’s research on pesticide safety behaviours among cocoa farmers underscores the significance of responsible agricultural practices (https://doi.org/10.1080/1059924X.2022.2148147). By embracing sustainable farming methods, we protect ecosystems, foster biodiversity, and ensure the health of our soil.

Agricultural Sustainability: The adoption of sustainable agricultural practices contributes to the reduction of greenhouse gas emissions. Through practices like agroecology, we not only grow our food but also nurture a climate-friendly environment. He noted that our choices in agriculture have a direct impact on mitigating climate change, ensuring a healthier planet for generations to come.

Reducing Carbon Footprint: Beyond mitigating climate change, sustainable agriculture plays a pivotal role in preserving biodiversity. By choosing sustainable practices, we become stewards of the planet, maintaining the delicate balance of ecosystems and ensuring the well-being of diverse plant and animal species.

Preserving Biodiversity: He encouraged the Environmental Research Society to serve as a beacon of change, empowering its members to drive transformative action. Armed with insights from our research at Earth and Environment Group, each member was encouraged to be an advocate for sustainable agriculture in their local communities. For example, by actively engaging in initiatives that promote responsible waste management, we sow the seeds of a greener future.

Empowering Change: He stated that the collective impact of individual choices cannot be overstated. Our call to action extends beyond personal behaviours to highlight the transformative power of united efforts. Through collaborative projects, advocacy initiatives, and global awareness campaigns, he emphasizes that every action, no matter how small, contributes to the global tapestry of sustainability.

Emphasizing Collective Impact: In concluding this exploration of sustainable agriculture and waste management, he reminded the society members that the choices we make today echo into the future. By embracing these practices, we cultivate not only a bountiful harvest but also a legacy of environmental stewardship for generations to reap. Let us, as members of the Environmental Research Society, be the custodians of change, nurturing a greener, more sustainable Earth for all. Together, we embark on a path towards environmental stewardship, one that honors the planet we call home.

Reviewing the triggers of an abrupt climate change event with Durham University’s Professor James Baldini

Published on by Gillian

On 8 December 2023, our Earth & Environment Research Group joined up with Teesside University’s student-led Environmental Research Society, to host a virtual talk by Durham University’s Professor James Baldini. Professor Baldini’s talk entitled ‘Meltwater, meteors, and volcanoes: the elusive cause of the Younger Dryas Event’ tackled the still hotly debated cause of the Younger Dryas Event (YDE).

Following the Last Glacial Maximum, the Northern Hemisphere was steadily warming until an abrupt return to near glacial conditions around 12,870 years ago. This abrupt cold event is a subject of intense debate with three hotly contested theories: glacial meltwater flooding into the North Atlantic, a meteor impact, and a high-magnitude volcanic eruption.

During the talk, Professor Baldini skilfully navigated through the pros and cons of each potential trigger, providing a balanced perspective, and debunking some common misconceptions about the Younger Dryas Event. Whether you’re a seasoned enthusiast in Earth and environmental sciences or simply curious about our planet’s intriguing history, this talk offers a captivating exploration into not only this, but the many similar events that occurred over the past 80,000 years of Earth’s climate.

The recording of Professor Baldini’s talk is available on our research group Teams site but anyone can catch a similar talk by Professor Baldini on the Northeast Geological Society’s YouTube Channel here https://youtu.be/Gqj0M8DpfoE?si=0IwZKqq7ZJlsdxZA. Don’t miss the chance to unravel the mysteries of the past and gain a deeper understanding of the forces that have shaped our planet.
