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.

The demographic dividend – the idea that a decline from high to low rates of population growth can lead to dramatic economic gains – has become something of a buzzword in development circles. Sub-Saharan Africa holds the single largest block of remaining high fertility countries and while headlines tend towards the dramatic about demographic shifts there, less column space has been devoted to examining the underlying issues causing these shifts or the other changes that will be necessary for countries to benefit from them.

In a recent post on the new United Nations population projections, I discussed the risk in assuming that countries in sub-Saharan Africa will progress through the demographic transition at a pace similar to other regions. Making this assumption is questionable because fertility decline in Africa has generally proceeded more slowly than in other parts of the world, with several cases of “stalls” and even small fertility increases over time.

Cambodia to grow by nearly one-third by 2050; Kenya to more than double; Mali to swell to three times its current size. These were the population projections available when Feed the Future, President Obama’s global hunger and food security initiative, was beginning implementation in 19 focus countries around the globe in 2010.

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.
