I am an ecologist and a biologist by training with research interests in wetland ecology and functioning and wildlife conservation. My current research primarily concentrates 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.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 north! There are, however, approximately 450 km2 of peatlands in the tropics, mainly located in Indonesia and Malaysia, but also in South and Central America and central 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. Globally, these peatlands store ~90 billion tonnes of carbon and also perform other important environmental and landscape functions (e.g. flood mitigation, wildlife habitat maintenance and livelihood support). My research on tropical peatlands began in 1993 in Central Kalimantan, Indonesian Borneo. From 1998 onwards I was a partner in various collaborative research programmes 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 regional universities and research institutes. This work focused primarily on forest biodiversity and the role of tropical peatlands in the global carbon cycle, and the impact of forest fires and illegal logging on peatland biodiversity and sustainability. I subsequently also became interested in investigating the 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 Laura Graham explored the ecological and social barriers to regeneration of peat swamp forest. More recent collaborations have been with Dr Vincent Gauci of the Open University and Prof. Chris Evans (CEH, Bangor) on dissolved organic carbon (DOC) losses from natural and degraded tropical peatland catchments in Indonesia. We currently co-supervise Matthew Kent (based at the OU) who is investigating the fate of fluvial DOC, specifically CO2 and CH4 evasion from the waterways draining intact and degraded peatlands, and Sarah Cook (based in the department) who is studying fluvial losses of DOC from oil palm plantations on peatland. These students follow earlier pioneering work by Sam Moore on the scale of DOC losses from degraded tropical peatlands.
Other related strands of my research have included the application of ALOS-PALSAR radar to monitor forest degradation in peat swamp forests which was tackled by Matthew Waldram, as part of the NERC-funded NCEO carbon cycle theme; the effects of fire on peat biogeochemistry, which Leanne Milner investigated with the support of a university scholarship and the EU-funded REDD-ALERT project led by the James Hutton Institute; spatial modelling of peat swamp forest by Zamzam Hassan, focusing on her home country of Brunei; exploration of the ecological and cultural services provided by peat swamp forest fish by Sara Thornton; and remote sensing of oil palm plantations on peat, being carried out by Valentin Louis. 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 is examining peat cores from across the globe, including tropical sites in Southeast Asia, and a further project led by Dr Vince Gauci (Open University) investigating methane emissions from wetlands forests. 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), while in my own department, Wayne Murphy is 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 Aberdeen), 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 and led on to involvement in consultancy work, including a report for ICCT on the scale of greenhouse gas emissions from oil palm plantations on tropical peatlands, and inputs as a Lead Author for the recently published IPCC guidelines for national greenhouse gas inventories: wetlands.
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. This work was started by former PhD student Ross Morrison and is being continued by Pan Gong and Alex Cumming, working with Dr Joerg Kaduk and Prof Heiko Balzter. The focus is on comparing the carbon balance of natural fenland versus rewetting pastures and agricultural land using eddy covariance techniques. This work has recently spun up into a DEFRA funded project led by Prof 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.
