Climate Change and India’s National Security: An Emerging Strategic Challenge
Updated on: December 26 , 2025

Climate change is no longer only an environmental concern; it is increasingly recognised as a national security challenge. For India, rising temperatures, extreme weather events and sea-level rise are already influencing food security, water availability, migration patterns and disaster response capabilities. These pressures have direct implications for internal stability and military preparedness.
Glacier retreat in the Himalayas affects river systems critical to millions, while coastal erosion threatens infrastructure and livelihoods along India’s long coastline. Extreme weather events place repeated strain on armed forces deployed for disaster relief, stretching resources and readiness. Climate-induced instability in neighbouring regions could also trigger cross-border humanitarian challenges.
Addressing climate security requires integrated planning across defence, infrastructure and governance. Investments in resilient infrastructure, early-warning systems and climate-adapted military logistics are becoming strategic necessities. As climate risks intensify, India’s ability to anticipate and manage these threats will be central to its long-term national security framework.
