South Asia's water conundrum: hydroclimatic and geopolitical asymmetry, and brewing conflicts in the Eastern Himalayas

Few regions in the world are nearing a large-scale water crisis as rapidly as South Asia, especially the basins in the Eastern Himalayas. Despite being known to be a water-rich part of the world, lack of integrated planning, and unfavourable natural and political settings have pushed this populous region towards basin-wide water scarcity, flood hazards, water quality and ecosystem degradation, and public health problems. Rapid growth of population and an unforgiving future climate complicate the situation and put millions more at risk. Meanwhile, the riparian nations continue unilateral efforts to develop their water resources without addressing the ecological integrity of the complex transboundary river system. This article provides an overview of the asymmetry in hydroclimatic conditions and unhelpful political realities that have pushed the region towards a looming large-scale water conflict.
