I am an ecologist and a biologist by training with research interests in wetland ecology and functioning and wildlife conservation. My current research activities primarily concentrate on the tropical peatlands of Southeast Asia, but I am also supervising research projects on peatlands in South America, Central Africa, as well as on lowland peatlands in the UK, rural biodiversity, wildlife conservation and the sustainable management of natural resources.
Many people still find it hard to believe that there are extensive peatlands in the tropical zone: after all, peat bogs are usually associated with the cool, wet, midge-infested regions of the world! There are, however, approximately 40 million ha of peatlands in the tropics, mainly located in the Southeast Asian countries of Indonesia and Malaysia, but also in South and Central America and Africa. In a natural condition, the peatlands in Southeast Asia support peat swamp forest, which provides a habitat for a number of rare and endangered species. Underground, the thick peat layers, accumulated over thousands of years and often exceeding a thickness of 10 m, store enormous amounts of carbon. These peatlands perform important environmental and landscape functions (e.g. flood mitigation, carbon sequestration, wildlife habitat maintenance), although these aspects of tropical peatlands are not well understood. In 1998 I became a partner in a four-year collaborative research programme that investigated the ecology and natural resource functions of these systems, funded by the European Union (EU). Fieldwork was based in Central Kalimantan, Indonesia and elsewhere within the Southeast Asian region, and involved working with Indonesian and Malaysian universities and research institutes. This work focused on forest biodiversity and the role of tropical peatlands in the global carbon cycle, whilst additional research, funded by the UK Government's Darwin Initiative, investigated the impact of forest fires and illegal logging on peatland biodiversity and sustainability. This included studies of the Bornean orang-utan, an endangered primate that is now largely restricted to peat swamp forest, and investigation of the impacts of the 1997/1998 forest fires on emissions of atmospheric carbon.
In 2002 a further EU funded project commenced with a focus on sustainable management strategies for tropical peatlands (STRAPEAT project). As an outcome, I was involved in the production of guidelines for the wise use of tropical peatlands (available on-line through the RESTORPEAT web pages, see link below) and, through a linked programme (PeatWise), the development of higher education teaching materials on sustainable land use in the humid tropics. At the end of 2004, I commenced work on a further EU-funded research programme (RESTORPEAT) investigating ecological restoration of degraded tropical peatland systems. This is particularly relevant to the peatlands of Kalimantan, which have been severely impacted by land development projects, drainage, fire and illegal logging. Working together with Dr Kevin Tansey and Agata Hoscilo, we investigated the role of fire in the land use dynamics and restoration of tropical peatlands, whilst with Jenny Pickerill and Laura Graham we explored the ecological and social barriers to regeneration of peat swamp forest. Commencing in 2006, aspects of this work were integrated into the EU project AIR-CO on water resource management in SE Asia. Working with two Indonesian universities and the lead partner, University of Wageningen, we developed research training and teaching materials to better understand human impacts on river and wetland management. This included commissioning a number of educational films. As an extension of this catchment approach, I began a collaborative project with Sam Moore (NERC-funded PhD student) and Dr Vincent Gauci of the Open University and Dr Chris Evans (CEH, Bangor) on dissolved organic carbon (DOC) losses from natural and degraded tropical peatland catchments in Indonesia. This was subsequently extended through funding by a NERC ‘Urgency’ grant to investigate DOC losses following the extensive 2009 peatland fires in Central Kalimantan.
New directions in tropical peatland research are currently being pursued. These include the application of ALOS-PALSAR radar to monitor forest degradation in peat swamp forests which is being tackled by Matthew Waldram, as part of the NERC-funded NCEO carbon cycle theme; the effects of fire on peat biogeochemistry, which Leanne Milner is investigating with the support of a university scholarship and the EU-funded REDD-ALERT project led by the James Hutton Institute; and PhD student Zamzam Hassan is investigating species and microclimate spatial modelling in peat swamp forest in her home country of Brunei. I am also a partner in a NERC-funded project led by Prof. Dan Charman (University of Exeter) exploring millennial scale peatland carbon dynamics, which will examine peat cores from across the globe, including tropical sites in Southeast Asia. My interests in tropical peatlands in South America and Central Africa have been enhanced by collaborations with Outi Lahteenoja (formerly at University of Turku in Finland) and Greta Dargie (PhD student working with Dr Simon Lewis at University of Leeds). Outi carried out her PhD on the peatlands of the Peruvian Amazon, whilst Greta is exploring wetlands in the Congo Basin. In our own department, Wayne Murphy is starting a PhD programme investigating wetlands in the Peruvian Amazon as a regional source of methane and nitrous oxide; this is part-funded by a NERC grant, led by Dr Yit Arn Teh (University of St Andrews), Dr Juan Carlos Berrio and myself.
My research on tropical peatlands has emphasized how important it is to convert scientific knowledge into policy and practice. This transfer of expertise and experience was facilitated by Dr Chris Banks and myself under the EU-funded CARBOPEAT project. Over a two year period, the CARBOPEAT partners from Europe and Southeast Asia, worked together to identify key issues and critical gaps in our understanding of tropical peatland carbon dynamics, analyse implications for policy, and formulate guidelines for optimizing the tropical peat carbon store that could be understood readily by policy makers and decision takers. This led on to involvement in consultancy work, including a recent report for ICCT on the scale of greenhouse gas emissions from oil palm plantations on tropical peatlands.
Closer to home, peatland research is focused on the fenlands of Eastern England, where schemes to re-wet former fenland now being used for agriculture may result in significant reductions in atmospheric carbon emissions. PhD students Pan Gong and Ross Morrison, working with Dr Joerg Kaduk and Prof Heiko Balzter, have been comparing the carbon balance of natural fenland versus rewetting pasture using eddy covariance techniques. This work has recently spun up into a DEFRA funded project led by Dr Chris Evans (CEH) evaluating the greenhouse gas and carbon balance of lowland peatlands across a number of sites in England and Wales, the results of which will ultimately inform government policies on peat land use options.
Current work on the conservation of biodiversity in the UK and elsewhere focuses on landscape approaches to habitat and species conservation, and the impacts of gentrification on rural nature. A RELU-funded scoping study on this topic was carried out during 2004-2005, whilst a current RELU project is investigating opportunities for climate adaptation and mitigation in rural communities in England. I am also supervising MSc and PhD research students working on various aspects of sustainable resource management, wildlife conservation and ecotourism, vegetation diversity and ethnobotanical use in Europe, Africa and Asia.
