Divya Delhi:  A crucial and commonly used resource throughout human history has been water. Early dwellers along rivers and ancient civilizations like the Indus Valley, Mesopotamia, and the Incas thrived near water. Thus, water and rivers remain vital to diplomacy and relations in the 21st century. India has recognized this reality with remarkable sharpness under Narendra Modi, turning water management from a local issue into a smart foreign policy tool, balancing shortage with regional stability. PM Modi's strategy stems from India's vulnerable water destiny, not abundance. A nation with 17% of the world's population and 4% of its freshwater reserves faces a catastrophe. Scarcity and inadequate water management have caused a paradigm change. Water is becoming a strategic asset used deliberately internationally, not only a development issue. This signals a shift from passive transboundary water management. Modi sees water as a tool for collaboration and strong diplomacy, not a cause of conflict. This administration realizes that water control gives geopolitical leverage in a water-stressed globe.
