Article
Full-text available
The world's most extensive tropical peatlands occur in the Cuvette Centrale depression in the Congo Basin, which stores 30.6 petagrams of carbon (95% CI, 6.3-46.8). Improving our understanding of the genesis, development and functioning of these under-studied peatlands requires knowledge of their topography and, in particular, whether the peat surf...

The sensitivity of tropical forest carbon to climate is a key uncertainty in predicting global climate change. Although short-term drying and warming are known to affect forests, it is unknown if such effects translate into long-term responses. Here, we analyze 590 permanent plots measured across the tropics to derive the equilibrium climate contro...

Structurally intact tropical forests sequestered about half of the global terrestrial carbon uptake over the 1990s and early 2000s, removing about 15 per cent of anthropogenic carbon dioxide emissions. Climate-driven vegetation models typically predict that this tropical forest ‘carbon sink’ will continue for decades. Here we assess trends in the c...

Science fields, including tropical peatland research, are facing persistent under-representation of women. In this perspective piece, we explore, as women at different stages of our career, our personal experiences of 'what is it like to be a woman working in tropical peatland science'? We collected our responses and analysed them thematically. Alt...
Article
Full-text available
The recent publication of the first spatially explicit map of peatlands in the Cuvette Centrale, central Congo Basin, reveals it to be the most extensive tropical peatland complex, at ca. 145,500 km². With an estimated 30.6 Pg of carbon stored in these peatlands, there are now questions about whether these carbon stocks are under threat and, if so,...
Technical Report
Full-text available
In January 2017, scientists announced new discoveries showing that the Central Congo Basin Peatlands form the largest area of peat swamp forest in the tropics. Estimates of soil organic carbon stocks in the Republic of Congo and Democratic Republic of Congo have radically increased as a result, to some 30 Gt. Degradation of these peat carbon stocks...
Book
Full-text available
Smoke on Water is a Rapid Response Assessment that looks at peatland location, extent, threats and the policies to manage and protect them. The goal of this rapid response assessment, carried out on behalf of UN Environment and based on the efforts of more than 30 contributors, is to raise awareness about the importance of the world's peatlands and...
Article
Full-text available
Peatlands have been widely studied in terms of their ecohydrology, carbon dynamics, ecosystem services and palaeoenvironmental archives. However, several assumptions are frequently made about peatlands in the academic literature, practitioner reports and the popular media which are either ambiguous or in some cases incorrect. Here we discuss the fo...
Article
Full-text available
Tropical forests are global centres of biodiversity and carbon storage. Many tropical countries aspire to protect forest to fulfil biodiversity and climate mitigation policy targets, but the conservation strategies needed to achieve these two functions depend critically on the tropical forest tree diversity-carbon storage relationship. Assessing th...
Article
Peatlands are carbon-rich ecosystems that cover just three per cent of Earth's land surface, but store one-third of soil carbon. Peat soils are formed by the build-up of partially decomposed organic matter under waterlogged anoxic conditions. Most peat is found in cool climatic regions where unimpeded decomposition is slower, but deposits are also...
Data
Tropical forests are global centres of both biodiversity and carbon storage. Many tropical countries aspire to protect forest to fulfil biodiversity and climate mitigation policy targets, but the conservation strategies needed to achieve these two functions depend critically on the tropical forest diversity-carbon relationship and this remains larg...
Article
Full-text available
Au moment où la gestion durable des écosystèmes forestiers requiert une parfaite connaissance de la flore, celle du Congo en général et particulièrement celle des forêts marécageuses du nord-Congo, demeure encore peu connue. La présente étude vise à contribuer à une meilleure caractérisation de la diversité floristique des forêts marécageuses de la...
Article
Full-text available
Our limited knowledge of the size of the carbon pool and exchange fluxes in forested lowland tropical peatlands represents a major gap in our understanding of the global carbon cycle. Peat deposits in several regions (e.g. the Congo Basin, much of Amazonia) are only just beginning to be mapped and characterised. Here we consider the extent to which...

Full-text available
Improved management of carbon storage by terrestrial biomes has significant value for mitigating climate change. The carbon value of such management has the potential to provide additional income to rural communities and provide biodiversity and climate adaptation co-benefits. Here, we quantify the carbon stores in a 49,300-ha landscape centered on...
Article
Full-text available
Reliable soil organic carbon (SOC) stock measurements of all major ecosystems are essential for predicting the influence of global warming on global soil carbon pools, but hardly any detailed soil survey data are available for tropical montane cloud forests (TMCF) and adjacent high elevation grasslands above (puna). TMCF are among the most threaten...
