Study region: The Brahmaputra River Basin.
Study focus: The Brahmaputra River Basin (BRB) is the most environmentally fragile and politically unstable transboundary river basin in South Asia. Therefore, incorporating the environmental sector into water-energy-food system analysis is necessary to better serve water resource management in the BRB. Integrated water resources system analysis can provide more perspectives for alleviating political tension and promoting cooperation in the basin. This study proposes a modeling framework to explore the water-energy-food-environment (WEFE) nexus and analyze transboundary cooperation opportunities in the BRB. Employing the framework, we attempt to answer three questions: (1) how can we understand the relationships between various sectors and coordinate their water demands? (2) How do these relationships influence riparian countries’ decisions? (3) What measures can promote the sustainable development of the BRB under climate change and water infrastructure development?
New hydrological insights for the region: The results show that the trade-off curve between economic benefits and environmental costs has declining marginal value in the BRB. When environmental constraints are raised, countries are more inclined to cooperate to obtain more economic benefits. Full cooperation in the BRB increases the economic benefits and prompts riparian countries to take a greener road among the shared socioeconomic pathways (SSP126). Water resource project construction can improve the utility of water resources in a country, thus enhancing its discourse power on benefit reallocation.
