India will face severe water shortages by 2025 as demand is projected to exceed available supply. One proposed solution is interlinking India's rivers to transfer water from surplus to deficit regions. The document discusses the history and technical details of various interlinking proposals. It also outlines both benefits such as flood control and drinking water availability, as well as criticisms such as large costs, environmental and social impacts, and technical challenges. Ultimately, it argues local water conservation and groundwater management may be more practical alternatives to the ambitious interlinking plans.
