Today, as El Niño-related droughts impact communities across East and Southern Africa, food aid shipment and distribution networks have shifted into high gear.

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.
