27. Part 1: Realizing the Potential of Maize in Sub-Saharan Africa* * Prepared with the collaboration of IITA. Introduction In the wake of the Green Revolu- tion of the 1960s and 1970s, when a sharp surge in wheat and rice production greatly reduced food imports in many developing coun- tries, an end to hunger appeared in sight. More recently, however, some of the greatest beneficiaries of the technological innovations of the 1960s and 1970s-including China, India, Pakistan, and Mexico-have experienced slower rates of growth in cereal production, and there is evidence that historical growth rates may be difficult to sustain (CIMMYT 1989). The realization has slowly been dawning that the Malthusian race between popula- tion growth and food production is not yet won, at least not in the de- veloping countries, and that the world's ability to feed itself is more precarious than had previously been thought. The problem of lagging food produc- tion is most evident in sub-Saharan Africa, a region largely unaffected by the technological innovations that so profoundly transformed the 1 Throughout this report, "Sub-Saharan Africa" and "Africa" are used inter- changeably to denote all countries in Africa except those in North Africa (Morocco, Algeria, Tunisia, Libya, and Egypt) and the Republic of South Africa. 2 The primary data sources used in prepar- ing this report include the AGROSTAT data base compiled by the Food and Agriculture Organization of the United Nations (FAO), as well as the World Development Report series published annually by the World Bank. Some of the data in these sources are questionable, particularly the African data, because official statistics are weak in a number of countries. Empirical results appearing in this report must therefore be interpreted with some degree of caution. world's wheat and rice economies.' Unlike Asia, where rice and wheat are the major staple foods, in Africa diets are based primarily on coarse grains (maize, millet, and sorghum) or on roots and tubers (cassava, yams, and sweet potatoes). Many African staple food crops did not benefit directly from the technologi- cal advances associated with the Green Revolution, either because improved seed-fertilizer technolo- gies were lacking for the African crops, or, if they were available, because government policies dis- couraged their adoption by farmers. As a result, food production in Africa has not kept pace with rising population. While population growth averaged 2.9% from 1961-65 to 1984-88 for the region as a whole, growth in cereal crop production averaged only 1.9% during the same period.2 Thus, per capital cereal production in Africa has actually fallen during the past 25 years, a phenomenon unparalleled elsewhere (Figure 1). Most African nations have re- sponded to widening food deficits by importing increasing amounts of cereals, primarily wheat and rice. Consumption of imported cereals has been encouraged by economic policies that have made imports cheaper than domestically produced staples, and by demographic changes (such as urbanization and women's entry into the formal labor market) which have increased the demand for convenience foods.
