Pakistan is a developing state with primary reliance on agriculture, its economic backbone. With huge debt deficit, weak infrastructure, poor governance, widespread corruption, rampant poverty and substantial defense expenditure, it shares the problems and concerns of Southern countries. Global climate change, a magnifying threat, portends disastrous effects on agriculture. Pakistan has witnessed devastating floods in 2010 and 2011 that almost paralyzed her infrastructure and exposed her vulnerabilities. Challenges caused by the climate change, such as, rapidly melting glaciers resulting in water scarcity, low agriculture yields leading to food insecurity, endangered coastlines, and population displacement are contributing to the crises of identity and authority. Limited water supply could also intensify existing intra and interstate trust deficit and worsen the conflicts. Global climate change could thus largely result in environmental and economic degradation and deterioration of state’s integrity. These multidimensional aspects of impending problems have generated a debate to look beyond the traditional national security parameters and incorporate the environmentalist version of security, which requires developing the adaptation capacity of a state.
