Asia, home to half of the world’s human population, has the fastest growing economies and urban development, along with highly diverse ecosystems. Asia is extremely vulnerable to ongoing climate change and human activities and both of these processes have significant influences on greenhouse gas dynamics. However, empirical data with adequate spatial and temporal resolution on greenhouse gas exchange between the atmosphere and biosphere or soil are lacking, making our understanding and predicting of greenhouse gases and their responses to global change very limited. Large uncertainties also exist on the contribution of Asia ecosystems to global greenhouse gas emissions. This session welcomes contributions on greenhouse gases dynamics across multiple spatial and temporal scales and their response to global change, which use observations, manipulative experiments, or biogeochemical models, to enhance our understanding of the key drivers of biogeochemical cycles from plots to regions.
