The Department is planning a 4-day field class to Somerset and the Quantocks in the middle of the Autumn term for all first year students in Geography & Environmental Science. The focus will be on flooding – prediction, monitoring, social and economic impacts etc. with lots of opportunities to get out into the field to observe and record. There will also be plenty of opportunity for students to work together in groups and to get to know each other and staff during an interesting and varied week in the beautiful landscapes of this part of part of Somerset.

Sarah Duddigan talks citizen science and the Tea Bag Index on TV
This week University of Reading and Royal Horticultural Society (RHS) PhD student Sarah Duddigan has been filmed for an Austrian children’s science TV programme, talking about her contribution to a decomposition rate citizen science project, known as the Tea Bag Index – UK.
The Tea Bag Index is a novel method to measure decomposition rate in soil. Decomposition (the breakdown of organic material into its smaller constituents) is an important process for the release of nutrients into soil for plants to use. Therefore gaining a better understanding of decomposition in soil will be of great value to gardeners in the UK. The method is simple, UK participants are recruited through the RHS and posted some tea bags to bury in their garden. After three months they dig them up and send them back, along with a soil sample.
Decomposition of organic matter (i.e. dead plant and animal remains) in soils is an important process in any ecosystem.
Decomposer microorganisms feed on the organic matter and break it down into its simplest components. As organic matter is decomposed, water, carbon dioxide and nutrients are released. Meaning that, any excess nutrients are released and are available for plants to use to grow.
Maintaining a healthy and vibrant garden is the aspiration of most gardeners and healthy fertile soil is a key component of this. Therefore, a better understanding of decomposition rates in garden soils will be of great value to gardeners across the UK.
While having an active microbial population decomposing organic matter is important for soil health, they are not without their problems. While organic matter is decomposing, it releases the greenhouse gas carbon dioxide (CO2) into the atmosphere. A fast decay leads to more CO2 in the atmosphere and slow decay could lead to a greater proportion of carbon remaining in the soil. It is estimated that soils store a gigantic 2,300 billion tons of carbon worldwide; triple the amount than all the worlds plants. Therefore in order to gain a better understanding of global CO2 emissions from soils it is vital to know more about the rate of decomposition.
The data from the UK therefore can also be combined with data being collected across Europe (or across the world in fact) in order to gain a better understanding on the role of decomposition in global carbon emissions and the contribution to climate change.
This seems to be a contradiction, on the one hand decomposition is good for plant health, but on the other has the potential to contribute to climate change. This is why projects such as this, which aim to gain a better understanding of decomposition rates in soil, are so important.

Winner of the 2015 BSc BSSS Dissertation Prize
Congratulations to Rosie Everett, winner of the 2015 BSc BSSS Dissertation Prize for her project on ‘Reconstructing Late Würm Late-Glacial and Early Holocene environmental changes in the Corsican uplands and evaluating the response of human groups to climate change and vegetation succession’ supervised by Dr Nick Branch (presenting the award).
Rosie’s project used the sedimentary records from Lake Creno, Corsica as an archive for past environmental conditions. She analysed the pollen stored in the sediment to reconstruct past conditions to see if there was a relationship between past climate during ate Wurm Late Glacial and Early Holocene period and human settlement on Corsica.
She has been putting her paleoecological skills to practice as a Forensic Researcher Intern at the James Hutton Institute, looking at rates of recovery of diatoms, taken from lake samples from pig liver tissues, as an analogue from human drowning cases. Rosie graduated this summer with a BA in Archaelogy, and is currently working with a forensics company, assisting with field work. Her ambition is to build on this experience and skills base to pursue post-graduate study in ecology.
We’re extremely proud of Rosie and all our students’ fantastic achievements this year. Competition for the prize this year was tough with many strong entries. We wish everyone from the Class of 2015 the best of luck with their future endeavours.
Dr Giuseppe Feola presents at 11th International Conference of the European Society for Ecological Economics
Dr Giuseppe Feola attended the 11th International Conference of the European Society for Ecological Economics (ESEE), which was hosted by the University of Leeds on 30 June – 3 July 2015. The European Society for Ecological Economics brought together scientists across traditional disciplines, and explored solutions for the transformation to a sustainable society.
Giuseppe made two presentations. In the first one, he reported results from a research project on institutional change and continuity of peasant communities in the Colombian Andes (project description here). This study increases our knowledge of peasant communities in this particular region, and adds to the body of scholarship that is refining our understanding of how institutions adapt and how culture changes in response to compounded climatic and economic disturbances. In the second contribution, Giuseppe presented a critical analysis of emerging concepts of societal transformation toward sustainability. This analysis provides structure to the scientific debate on transformation toward sustainability, and identifies two priorities for future research, namely to foster dialogue around the complementarities of different concepts, and to test different concepts empirically (full paper available here).

Lecturer Dr Hilary Geoghegan hosts citizen science conference
On 12th May, one of our lecturer’s Dr Hilary Geoghegan hosted a citizen science conference at the British Ecological Society in London. Working with colleagues from the Stockholm Environment Institute at the University of York, Hilary welcomed participants for a one-day event to discuss the ‘human’ element of citizen science – specifically the volunteers, professional scientists, practitioners and policymakers that make up this ever-growing field.
The event attracted over 40 researchers and practitioners interested in the social dimensions of citizen science. A widely accepted definition of citizen science is the participation of non-professionals in professional science projects. However, more work needs to be done to reflect on participation in citizen science – a research approach that is developing at a breakneck pace. Dr Geoghegan said: “My research area of enthusiasm, namely the emotional affiliation we have towards things and activities we care about, is of significant interest to professional scientists, research councils and policymakers as they establish the ways in which they will engage with citizen science in the future. Without an understanding of why people do and do not participate, citizen science projects may fail.” You can find tweets on the subject via the hashtags #BESCitSci and #CitSciPeople
Dr Geoghegan holds an ESRC Future Research Leader award and has used the time and resources offered by the grant to examine the social aspects of tree health citizen science. She has been interested in the place of ‘citizen science’ within emerging tree health policy and the enthusiasm of scientists, policymakers, press officers, web editors and database managers for citizen science. Her next step is to interview volunteers in tree health citizen science projects to understand why they survey and monitor trees.
In 2013 Dr Geoghegan joined the Department of Geography and Environmental Science and since then she has travelled to Australia to discuss enthusiasm for trees in Melbourne and Sydney. She has also spent time building networks with colleagues in Biological Sciences on tree health. She is a founder of the UK’s Tree Health Citizen Science Network.
If you’re interested in this area and would like further information please contact Hilary: h.geoghegan@reading.ac.uk or follow her on Twitter: @DrHG. She also hosts a blog www.hilarygeoghegan.wordpress.com focussing on life as an academic and her research interests.
Reading academics present soil science research to Sainsbury’s Farming Scholars
Professor Chris Collins and Dr Tom Sizmur gave presentations to a workshop on Soil Health and Management at Imperial College. The event marked the launch of the Inaugural Sainsbury’s Farming Scholars programme.
The Farming Scholars are representatives of growers that supply Sainsbury’s and are motivated to apply the latest scientific evidence to improving the sustainability of their operations and manage their soils more effectively.
Chris Collins introduced the current programme of soil science research recently funded by NERC and BBSRC, including the STARS (Soils Training And Research Studentships) Centre for Doctoral Training and the ‘Soil & Rhizosphere Interactions for Sustainable Agri-ecosystems’ (SARISA) programme. Chris introduced his role in co-ordinating these activities across the country along with his administrative, and communications team based at The University of Reading
Tom Sizmur introduced some preliminary data from a suite of experiments at Rothamsted Research that he worked on as a postdoctoral researcher. The experiments reveal that the addition of organic matter to soils can rapidly increase earthworm number and biomass in soils. The earthworms break-up, incorporate and mix the organic materials into the soil. This is essentially a form of ‘biological cultivation’ which improves the structure of the soil, via the formation of aggregates and connected pore networks. He revealed that the structure of the soil was modified by the presence of earthworm burrows which makes it easier for plant roots to penetrate and for water to infiltrate. The larger, deeper root network that resulted from ‘biological cultivation’ increased the yield of cereal crops.
New book on “Biodiversity in Ecosystems – Linking Structure and Function” by Dr Shovonlal Roy
A new book on “Biodiversity in Ecosystems – Linking Structure and Function” coedited by Dr Shovonlal Roy has just been published. All the chapters of the book can be accessed freely from the following link:
http://www.intechopen.com/books/biodiversity-in-ecosystems-linking-structure-and-function
“The term biodiversity has become a mainstream concept that can be found in any newspaper at any given time. Concerns on biodiversity protection are usually linked to species protection and extinction risks for iconic species, such as whales, pandas and so on. However, conserving biodiversity has much deeper implications than preserving a few (although important) species. Biodiversity in ecosystems is tightly linked to ecosystem functions such as biomass production, organic matter decomposition, ecosystem resilience, and others. Many of these ecological processes are also directly implied in services that the humankind obtains from ecosystems. The first part of this book will introduce different concepts and theories important to understand the links between ecosystem function and ecosystem biodiversity. The second part of the book provides a wide range of different studies showcasing the evidence and practical implications of such relationships.”

Research Profile: Dr Agatha Herman
Dr Agatha Herman is Lecturer in Human Geography with interests in ethics, geographies of justice and international development. In September 2014 Agatha began her Leverhulme Trust Early Career Fellowship in which she is exploring ‘the power of Fairtrade’ to bring about sustainable and empowering development both to and beyond its producer communities.
In recent years there have been growing criticisms of the certified Fairtrade movement both in academia and the media. However there has been a significant lack of research actually exploring the impact which Fairtrade has on the producer communities. Thanks to a British Council Researcher Links Travel Grant, since January Agatha has been in South Africa working with the Fairhills Association at Du Toitskloof Cooperative Cellar and Bosman-Adama (both Fairtrade wine producers) to really understand their experiences; focus groups and photo elicitation exercises with the farmworkers have illuminated the progress which has been made but also the continuing challenges they face.
She says, ‘I think that what makes my research so useful is that it helps producers identify their strengths and areas for improvement, and will give consumers a clearer idea of what their Fairtrade purchases are actually supporting. The need for Fairtrade and the context in which it finds itself varies from country to country so my research will take me to all of the current Fairtrade wine producing countries – South Africa, Chile, Argentina, Lebanon and Tunisia – in order to fully understand the system and its developmental impacts. In turn, this will help to strengthen the Fairtrade system itself by making it more effective, transparent and responsive.’
Agatha’s research interests in resilience and development in production systems as exemplified here connect into broader interests in food politics, ethics and power relations.
In recognition of her dedication Agatha has been invited to return as a visiting scholar to the Ruralia Institute at the University of Helsinki (Finland), where she will further her research on social resilience and cultural connections within agriculture through new writing collaborations as well as speaking about her findings so far in both the Mikkeli and Seinäjoki units. On route she will be stopping off in Bonn (Germany) to develop new connections with Fairtrade International in order to better understand the global systems and relations of Fairtrade in terms of its standards, how they are put into practise and how they connect into the international development aims of the organisation. To learn more about the contemporary fair trade movement, take a look at her forthcoming co-authored chapter with Mike Goodman in The Handbook of Research on Fair Trade, which will be published in June 2015.

Mountains warming faster, say scientists
An international team of scientists is calling for urgent and rigorous monitoring of temperature patterns in mountain regions after finding evidence that high elevations could be warming faster than previously thought.
The research team says that without substantially better information, we risk underestimating the severity of a number of already looming problems, including water shortages and the possible extinction of some alpine flora and fauna.
The research is published today in the journal Nature Climate Change.
Co-author Dr Maria Shahgedanova, University of Reading, said: “The evidence that mountains are warming faster than low elevations is growing but we still lack detailed information from both observations and models and, as a result, cannot reliably assess impact of the high-elevation warming. These can potentially affect not only high-altitude ecosystems but also water supply from snow and glacier ice and hazards associated with shrinking cryosphere which will impact population at lower elevations.
“To address the issue of elevation-dependent warming and its impacts, we need to employ a combination of automated ground-based measurement networks in different mountainous systems, high-resolution models and satellite imagery. Scientists from the University of Reading work on the development of all three components in the mountainous regions of Europe and Asia.”
The most striking evidence that mountain regions are warming more rapidly than surrounding regions comes from the Tibetan plateau. Here temperatures have risen steadily over the past 50 years and the rate of change is speeding up. But masked by this general climate warming are pronounced differences at different elevations. For example, over the past 20 years temperatures above 4,000 m have warmed nearly 75 per cent faster than temperatures in areas below 2,000 m.
The team of scientists came together as part of the Mountain Research Initiative, a mountain global change research effort funded by the Swiss National Foundation. The team includes scientists from the UK, US, Switzerland, Canada, Ecuador, Pakistan, China, Italy, Austria and Kazakhstan. Between them, they have studied data on mountain temperatures worldwide collected over the past 60-70 years.
Lead author, Dr Nick Pepin, of the University of Portsmouth said: “Most current predictions are based on incomplete and imperfect data, but if we are right and mountains are warming more rapidly than other environments, the social and economic consequences could be serious, and we could see much more dramatic changes much sooner than previously thought.”
Improved observations, satellite-based remote sensing and climate model simulations are all needed to gain a true picture of warming in mountain regions, the researchers say. Much of that requires international agreement and collaboration – and funding.
Among the reasons the researchers examined for faster rates of temperature increase in mountain regions are:
– Loss of snow and ice, leading to more exposed land surface at high elevation warming up faster in the sun;
– Increasing release of heat in the high atmosphere. A warmer atmosphere holds more moisture, which, when condensing as clouds at high elevation, releases more heat to the mountain environment;
– Aerosol pollutants at low elevations, including haze, dust and smoke, reduces warming at those elevations, thus increasing the difference in rates of warming between low and high elevations;
– Dust and soot deposited on the surface at high elevations causes more incoming sunlight to be converted to heat;
– The complex combination of any or all of the above factors in different regions and at different times of the year.
Records of weather patterns at high altitudes are ‘extremely sparse’, the researchers found. The density of weather stations above 4,500 m is roughly one-tenth that in areas below that elevation. Long-term data, crucial for detecting patterns, doesn’t yet exist above 5,000 m anywhere in the world. The longest observations above this elevation are 10 years on the summit of Kilimanjaro.
