The disastrous flooding in the Himalayan state of Uttarakhand this summer, which claimed more than 6,000 lives, was the outcome of a changing climate and poorly planned development. It was also another case in point of the increasing importance of environmental security in India – especially for the military.

To use the military parlance, climate change is often considered a “threat multiplier,” challenging stability and development around the world by exacerbating underlying conditions of vulnerability. South Asia is one region that faces multiple stressors that have the potential to feedback off each other.

Higher temperatures, more extreme weather, rising sea levels, flooding, and increased cyclonic activity in the Bay of Bengal and the Arabian Sea are reshaping the environment, warns the Center for American Progress (CAP) in a report.

Earth’s climate is changing, whether you like it or not. As it does, other changes – like rising sea levels or falling crop yields – follow. It is easy to see how this might lead to conflict. Competition for ever scarcer resources such as arable land and its bounty can turn ugly. As the price of food rises the poor, who spend more of their income on it, are hit more than the rich, exacerbating income inequality and leading to disaffection, resentment and, possibly, violence.

According to the UN, the planet has warmed faster since the turn of the century than any other period on record. Sea-level rise has also increased pace to 0.12 inches a year – almost double the rate observed during the 20^th century. This “unprecedented” rate of climate change is expected to disproportionally impact developing countries, whose socio-economic, political, and physical landscapes make them particularly vulnerable to the effects. The GAIN Index, an interactive mapping tool recently acquired by the University of Notre Dame, can help policymakers prepare for these changes by comparing the climate change vulnerability and readiness of countries around the world.

Phan Dinh Duc leans against yellow sacks of freshly harvested rice. It’s a warm spring evening in Vietnam’s Mekong Delta, and Duc, a local farmer, is waiting for traders to arrive by truck to purchase his produce and sell it on commodities markets. Beyond him lies a vast checkerboard of rice paddies, each filled with water and bordered by a network of canals and roughly 10-foot-high earthen dikes. They enable year-round rice cultivation in an area where, a half century ago, vast floodplains typically lay fallow for half the year and farmers planted one annual rice crop that grew in tandem with seasonal floods.

A staggering amount of development dollars – one in three, in fact – are lost due to natural disasters and crises. Certain communities are less affected than others by such disasters; they are more resilient. Knowing where vulnerability and strength exist and how to bolster them could help avoid these losses. Yet, today, very little data exists to help development practitioners understand which adaptive capacities are lagging in a given community.
