             abstract = "Peatlands are carbon-rich ecosystems that cover 185423 million 
                         hectares (Mha) of the earth's surface. The majority of the world's 
                         peatlands are in temperate and boreal zones, whereas tropical ones 
                         cover only a total area of 90170 Mha. However, there are still 
                         considerable uncertainties in C stock estimates as well as a lack 
                         of information about depth, bulk density and carbon accumulation 
                         rates. The incomplete data are notable especially in tropical 
                         peatlands located in South America, which are estimated to have 
                         the largest area of peatlands in the tropical zone. This paper 
                         displays the current state of knowledge surrounding tropical 
                         peatlands and their biophysical characteristics, distribution and 
                         carbon stock, role in the global climate, the impacts of direct 
                         human disturbances on carbon accumulation rates and greenhouse gas 
                         (GHG) emissions. Based on the new peat extension and depth data, 
                         we estimate that tropical peatlands store 152288 Gt C, or about 
                         half of the global peatland emitted carbon. We discuss the 
                         knowledge gaps in research on distribution, depth, C stock and 
                         fluxes in these ecosystems which play an important role in the 
                         global carbon cycle and risk releasing large quantities of GHGs 
                         into the atmosphere (CO2 and CH4) when subjected to anthropogenic 
                         interferences (e.g., drainage and deforestation). Recent studies 
                         show that although climate change has an impact on the carbon 
                         fluxes of these ecosystems, the direct anthropogenic disturbance 
                         may play a greater role. The future of these systems as carbon 
                         sinks will depend on advancing current scientific knowledge and 
                         incorporating local understanding to support policies geared 
                         toward managing and conserving peatlands in vulnerable regions, 
                         such as the Amazon where recent records show increased forest 
                         fires and deforestation.",
