“…All previous studies of tropical peat emission factors have been laboratory studies of Sumatran (Christian et al, 2003) or Kalimantan (Stockwell et al, 2014) peat, and only one other comprehensive in situ study of peat fires in Kalimantan (Stockwell et al, 2016). Hamada et al (2013) and Huijnen et al (2016) both provide information for a limited range of species (CO 2 , CO, CH 4 ) Note. Uncertainties were calculated in quadrature from those associated with the trace gas emission ratios and a ±10% uncertainty in the assumed fuel carbon.…”

Fires in tropical peatlands account for >25% of estimated total greenhouse gas emissions from deforestation and degradation. Despite significant global and regional impacts, our understanding of specific gaseous fire emission factors (EFs) from tropical peat burning is limited to a handful of studies. Furthermore, there is substantial variability in EFs between sampled fires and/or studies. For example, methane EFs vary by 91% between studies. Here we present new fire EFs for the tropical peatland ecosystem; the first EFs measured for Malaysian peatlands, and only the second comprehensive study of EFs in this crucial environment. During August 2015 (under El Niño conditions) and July 2016, we embarked on field campaigns to measure gaseous emissions at multiple peatland fires burning on deforested land in Southeast Pahang (2015) and oil palm plantations in North Selangor (2016), Peninsula Malaysia. Gaseous emissions were measured using open‐path Fourier transform infrared spectroscopy. The IR spectra were used to retrieve mole fractions of 12 different gases present within the smoke (including carbon dioxide and methane), and these measurements used to calculate EFs. Peat samples were taken at each burn site for physicochemical analysis and to explore possible relationships between specific physicochemical properties and fire EFs. Here we present the first evidence to indicate that substrate bulk density affects methane fire EFs reported here. This novel explanation of interplume, within‐biome variability, should be considered by those undertaking greenhouse gas accounting and haze forecasting in this region and is of importance to peatland management, particularly with respect to artificial compaction.

“…The DL site (S2°19′24″, E114°1′14″) was clear-felled and uncontrollably drained by a large-sized drainage canal system in the mid-1990s as part of a massive land conversion venture called the Mega Rice Project. The site has been fire-affected during 1997/98, 2002(Hoscilo et al 2011, Hamada et al 2013, and the estimated loss of the uppermost peat profile is approximately 0.7 m (Hirano et al 2014). Ferns are the main vegetation in the area (e.g.…”

“…IPCC guidance [62] on GHG emission factors for fires on organic soils is derived from only four studies, with only one addressing tropical peat fire emissions. While two subsequent studies [63] (Tom Smith 2015, personal communication) confirm that IPCC tropical peat emission factors for CO 2 and CO are of the correct order of magnitude they also highlight variability in CH 4 emissions. Given the high global warming potential of this gas (25 times that of CO 2 over a 100 year time scale [64]) this could have critical implications for the climate impact of peat fires and further studies are warranted to better understand the controls on fire-driven CH 4 emissions.…”

Peatlands are a significant component of the global carbon (C) cycle, yet despite their role as a long-term C sink throughout the Holocene, they are increasingly vulnerable to destabilization. Nowhere is this shift from sink to source happening more rapidly than in Southeast Asia, and nowhere else are the combined pressures of land-use change and fire on peatland ecosystem C dynamics more evident nor the consequences more apparent. This review focuses on the peatlands of this region, tracing the link between deforestation and drainage and accelerating C emissions arising from peat mineralization and fire. It focuses on the implications of the recent increase in fire occurrence for air quality, human health, ecosystem resilience and the global C cycle. The scale and controls on peat-driven C emissions are addressed, noting that although fires cause large, temporary peaks in C flux to the atmosphere, year-round emissions from peat mineralization are of a similar magnitude. The review concludes by advocating land management options to reduce future fire risk as part of wider peatland management strategies, while also proposing that this region's peat fire dynamic could become increasingly relevant to northern peatlands in a warming world.This article is part of the themed issue 'The interaction of fire and mankind'.
