Bangladesh has recently greenlit one of the most significant river management initiatives in its history: the Padma Barrage. This ambitious project aims to address the acute water scarcity issues plaguing the drought-affected southwestern regions of the country. However, the timing of this development raises serious concerns about the stability of water resources across South Asia, as several countries are locking horns in a race to construct dams along major rivers.
China is making headlines with its construction of the world’s largest hydropower dam on the Brahmaputra River, while India is ramping up its own dam-building efforts. Adding to this growing tension, the bilateral treaty governing the sharing of Ganges waters between India and Bangladesh is set to expire in December 2026, leaving the future of water distribution in a precarious position. Instead of fostering cooperation in addressing regional water insecurity, the Padma Barrage may inadvertently contribute to a cycle of unilateral river management decisions that could have detrimental impacts across borders.
Proponents of the Padma Barrage argue that it is a necessary response to the persistent water crisis faced by Bangladesh. The nation is situated at the end of the extensive Ganges-Brahmaputra river system, where rivers sourced from the Himalayas meander through numerous channels before reaching the ocean. Despite the apparent abundance of water, the main river channels are experiencing severe reductions in flow during the summer months, while several smaller rivers are at risk of vanishing altogether.
The dilemma facing Bangladesh is not one of its own making. The construction of the Farakka Barrage in India during the 1970s has redirected significant quantities of water toward Kolkata, India’s bustling metropolis, in an effort to clear sediment buildup from its port. This diversion has had adverse consequences for Bangladesh, particularly in reducing the flow of the Ganges River as it enters the country. The cumulative impact of upstream projects has compounded the already precarious water situation in Bangladesh, leading to increasing tensions over resource management.
As South Asia embarks on this collective dam-building frenzy, the absence of robust institutional frameworks for equitable water sharing further complicates matters. The race for dam construction, driven by a mix of national interests and immediate needs, threatens to escalate regional conflicts over water rights. Stakeholders in Bangladesh, India, and China must recognize that unilateral actions can lead to long-term adverse consequences not only domestically but also for neighboring countries reliant on shared water resources.
Moving forward, it is imperative that nations in South Asia engage in collaborative discussions and formulate strategies to manage their water resources sustainably. Instead of racing to build more dams, countries should prioritize dialogue and cooperation, paving the way for comprehensive agreements that ensure equitable access to water. Only then can South Asia hope to overcome its looming water crisis and foster stability in the region.
