River systems provide ecosystem services crucial for sustaining rapidly expanding population centers in across Asia. Despite far-reaching environmental impacts, human-induced perturbations such as water pollution have rarely been linked to carbon (C) export and greenhouse gas (GHGs) evasion from Asian rivers. The proposed research aims to build a research network on C fluxes through Asian river systems to assess water pollution impacts on Asian rivers as a C source. The project will take a unique approach combining review and synthesis workshops and exploratory field studies. Each year a workshop will be held in a regional hub – Yellow River (East Asia), Mekong River (Southeast), and Ganges-Brahmaputra (South) – to synthesize long-term data available from local sources and to conduct a field trip and follow-up samplings. Standardized protocols for monitoring riverine C fluxes will be disseminated among project members and research communities via workshop sessions and dedicated web pages. Long-term data from local sources and new data from field studies will be integrated into regional-scale syntheses of riverine C fluxes and water quality to provide the first regional assessment of water pollution impacts on Asian rivers as a source of C to the atmosphere and recommendations for water management options integrating water quality and GHG emissions.
