Research has shown that the amount of calories consumed per person had actually increased in all of west Africa, but had decreased in all east African countries between 1961 to 2009 despite the region having some of the most fertile agricultural land available on the continent.
In 1961 every nation in Africa produced domestically more than 100 percent of its domestic food supply. Now most African countries produce less than its domestic supply and therefore are becoming more dependent on food imports, even though they grow enough food to feed themselves.
In Benin, Mozambique and the two Sudans all show large drops in the portion domestically produced, and large increases in imported food and stock variations. Sudan and Mozambique can be partly explained by the wars that plagued both, but during the first part of this century Mozambique has had a domestic peace in a nation with extraordinary agriculture potential. The research showed that post-harvest loss is the major problem in the Sudans and not weather conditions. The same is true for Rwanda, Burundi, Uganda and Mozambique. Africa lacks infrastructures for adequate storage and refrigeration.
