The status of tropical peatlands, one of Earth’s most efficient natural carbon stores, is of increasing international concern as they experience rising threat from deforestation and drainage. Peatlands form over thousands of years, where waterlogged conditions result in accumulation of organic matter. Vast areas of Southeast Asian peatlands have be...
Soil nitrogen transformations underpin plant growth and are fundamental to healthy ecosystem functioning. Excess nitrogen applications, particularly in the form of high fertilizer inputs, adversely affect soil health and cause substantial nitrous oxide and ammonia emissions, contributing to climate change and atmospheric pollution. Understanding ni...
Contrasting tillage strategies not only affect the stability and formation of soil aggregates but also modify the concentration and thermostability of soil organic matter associated with soil aggregates. Understanding the thermostability and carbon retention ability of aggregates under different tillage systems is essential to ascertain potential t...
The management of agricultural soils affect the composition and scale of their greenhouse gas (GHG) emissions. There is conflicting evidence on the effect of zero-tillage on carbon storage and GHG emissions. Here we assess the effects of zero-tillage over a range of time frames (1–15 years) on carbon storage and GHG release and their controls in th...
Tropical peatlands are complex and globally-important ecosystems that are increasingly threatened by anthropogenic disturbances, primarily via agricultural development. Microbes in peatlands play important roles in governing overall ecosystem functions and sustenance, with specific population dynamics governing carbon sink or source dynamics. We de...

Conversion of tropical peat swamp forest to drainage-based agriculture alters greenhouse gas (GHG) production, but the magnitude of these changes remains highly uncertain. Current emissions factors for oil palm grown on drained peat do not account for temporal variation over the plantation cycle and only consider CO2 emissions. Here, we present dir...
Accurate assessment of tropical peatland carbon dynamics is important to (a) determine the size of the active carbon pool, (b) estimate the scale of transfers of peat-derived greenhouse gases (GHGs) to the atmosphere resulting from land use change, and (c) support carbon emissions reduction policies. To date, information on the quality of tropical...
Tropical peatland ecosystems are a significant component of the global carbon cycle and feature a range of distinct vegetation types, but the extent of links between contrasting plant species, peat biogeochemistry and greenhouse gas fluxes remains unclear. Here we assessed how vegetation affects small scale variation of tropical peatland carbon dyn...
Zero-tillage (ZT) is being increasingly adopted globally as a conservationist management system due to the
environmental and agronomic benefits it provides. However, there remains little information on the tillage effect on soil pore characteristics such as shape, size and distribution, which in turn affect soil physical, chemical and biological pr...
This expedition was the final expedition, of a set of three planned annual British Exploring Society expeditions to Namibia, in Damaraland in Northern Namibia. On this expedition the Young Explorers spent time in the Ugab River region and also undertook a 70 km expedition, by foot, to the Skeleton Coast. The Young Explorers came for either five wee...
Projects
Project (1)
1) Measure the amount of carbon stored in freshwater and coastal wetlands (e.g. mangroves, salt marshes, ombrotrophic bogs).
2) Assess bulk and molecular level chemical changes in order to understand how mans activities alter organic matter stability and or bio degradation.
3) Assess the interaction between natural C and anthropogenic compounds.
4) Develop rapid screening techniques (e.g. Rock-Eval pyrolysis, FTIR and other ) to evaluate changing organic and mineral components in freshwater and coastal peatlands.
