Greenhouse gas emissions from inland waters: A perspective and research agenda for the tropics and subtropics
peer reviewedStrong consensus indicates that inland waters emit globally significant quantities of greenhouse gases such as carbon dioxide, methane, and nitrous oxide. Tropical inland waters are often considered major contributors to higher greenhouse gas fluxes, yet accurate estimates of aquatic greenhouse gas fluxes are limited for the tropics. We provide a historical perspective on research carried out across low latitudes since the 1980s, synthesize current understanding of the sources and drivers of greenhouse gas emissions, and highlight priority research areas for future tropical inland water greenhouse gas research. We show that much of the focus has been on the humid tropics while the wet-dry, (semi)arid, and mountainous regions remain underrepresented in global datasets. Consistent and reliable greenhouse gas emission estimates will require (1) addressing the observational mismatch with new data from understudied ecoregions, (2) favoring direct and high-resolution carbon dioxide measurements over indirect estimates based on water chemistry parameters, (3) developing approaches that cross boundaries between ecosystem types and scales, and (4) sharing and publishing data more systematically
