Niger experienced famine conditions in 2008 despite exporting food to other countries. While the common myth is that world population growth outpaces food supply, the facts show global food production exceeds caloric needs and has increased more than population growth. Niger's food shortages are due to its landlocked position in western Africa along the Niger River and reliance on the southern savanna for most of its population, making it vulnerable to drought and desertification in the Sahara region to the north.
