Many factors have contributed to the food shortage in Africa, including natural disasters such as drought, pests and diseases and climate change as of 2015. Political factors such as corruption, military conflict and the lack of emergency plans also play parts in the crisis. Development problems such as rapid population growth and dependence on cash crops also contribute to the problem.
Drought is one of the most important factors in Africa's current food crisis, and recent years have brought more droughts of greater intensity than commonly occurred in the past in Africa. Many scientists believe that the severe weather could be a sign of major climate change, explains Harvest Help.
The ongoing wars in many areas of Africa make it difficult for people to produce food. Armies come through and steal people's stores, or people are driven from their land before harvest. Corrupt governments may demand what little their people do produce to continue their wars and regimes. These problems can also make it very difficult for outside relief to reach people in need.
Monoculture can exacerbate the problem. Instead of working the land to feed themselves, people in many developing nations produce cash crops that they sell or trade for their necessities. This makes them dependant on global trade and vulnerable to price fluctuations. This agricultural practice can also degrade the soil, making it more difficult to produce any crops.
