Redefining Water Wars: The Impact of Climate Change on South Asia’s River Conflicts
Keywords:
Climate Change, South Asia, Indus River Basin, Water Conflicts, Indus Waters Treaty, Nuclear SecurityAbstract
The Indus River, essential for approximately 300 million people, is transitioning from a geopolitical flashpoint to a socioecological system increasingly threatened by climate change. Accelerated glacial retreat, rising temperatures, and unpredictable monsoon patterns are diminishing seasonal water flows and exacerbating floods, droughts, and water scarcity, as evidenced by the devastating floods in Pakistan in 2022 and the severe drought in India in 2023. Climate models forecast a potential reduction of up to 20% in water discharge by 2050. These alterations heighten long-standing tensions between India and Pakistan, particularly exacerbated by hydropower projects such as Ratle, which adversely affect the Indus Delta and destabilize vulnerable glacial regions. This situation results in population displacement, ecological degradation, and heightened political instability. Nonetheless, shared vulnerabilities may present opportunities for cooperation, such as the establishment of bilateral adaptation funds for glacier monitoring, drought-resistant agricultural practices, solar desalination, and the collaborative sharing of hydrological data. By reconsidering the Indus Waters Treaty through a climate-focused perspective, it may be feasible to promote cooperative management, perceiving water as a resource for trust-building rather than a tool for conflict.
