The people of northern Kenya currently face many daily hardships. Primarily pastoralists by livelihood, their cycle of life focuses on the basics – securing food and water for family and livestock, constructing shelter from the unforgiving sun, and finding sustenance when periodic droughts ravage the region. A 2011 drought affected millions of people, and tens of thousands of livestock died. Approximately 90 percent of the area’s population lives below the poverty line.

Today approximately 44 percent of the world’s 7.2 billion people are under 24 years old – and 26 percent are under 14. Of those 7.2 billion people, a staggering 82 percent live in less developed regions of the world – primarily sub-Saharan Africa and Asia. Currently, the global median age is 29.2 years old, a sharp contrast to Europe, for example, where the median age is 41.

It is difficult to find a country feeling the negative impacts of climate change more severely than Bangladesh. Name any alarming, seemingly far off effect of a warming world being discussed in the halls of Washington or the summits of Copenhagen, and there is a good chance Bangladesh is experiencing it today. Flooding, drought, sea level rise, mass migration, and crushing poverty are exacerbated by a growing population and rapid urbanization. This perfect storm of climactic and demographic trends presents a looming crisis for Bangladesh, no more so than when it comes to food security.

In the wake of food riots in more than 30 countries in 2008 and the Arab Spring, in which food prices played an instigating role, the relationship between food security and instability demands a closer examination. “There is a lot of data on conflict, and a lot of data on food security, but it’s rarely brought together,” said Emmy Simmons, the author of the latest edition of ECSP Report. [Video Below]

Sub-Saharan Africa is not only the fastest growing region of the world demographically but is also one of the most vulnerable to climate changes, according to many measures, and already facing natural resource scarcity in many areas. These factors combine with existing development challenges to create security threats that African governments and the United States should be concerned with, says ECSP Director Roger-Mark De Souza in a presentation for the Africa Center for Strategic Studies’ introductory course on demography and the environment at the National Defense University.
