    Malnutrition is generally not perceived to be a pervasive problem in much of Africa, except during famines. There is little doubt that in "average" years, malnutrition in Africa is a smaller problem than it is in Asian countries such as Bangladesh, India, Nepal, or Sri Lanka. Another reason why nutritional problems do not receive much attention in Africa is that in recent years episodes of severe drought, famine, and starvation have been relatively frequent, and attention has focused more on the shorter-run alleviation of food problems than on longer-term underlying problems.

    Oyejide's chapter poses the problem of choice of policy instruments. As political motivations dominate in many countries in sub-Saharan Africa, the choice of policy instruments has been very often erratic. Oyejide clearly illustrates this dilemma. Protection under an inward-looking regime combined with overevaluation has directed resources away from the agricultural sector in Nigeria, inflicting heavy cost on rural consumers and producers while subsidizing urban consumers.

    The humid and subhumid tropics in African regions where rainfall exceeds potential evapotranspiration for five months or more include most of the area from Guinea through central Africa plus the southern part of East Africa. They cover 12 million square kilometers, or 43 percent of the total land area, and include the humid forest zone of central Africa. Rainfall is over 1 thousand millimeters per annum.

    The organization of maize marketing in Zambia reflects the main objective of the system—supplying urban areas with cheap food. Maize purchased from farmers is sold only to the major milling companies, all of which are located in urban centers. The marketing subsidy, reflected in the low sale price to these millers, is in effect a subsidy to mainly urban consumers. Rural retailers are allowed an explicit markup to cover transport costs back to rural areas.

    Asie

    This report reviews the recurring costs situation for irrigation in Asia. These are the costs associated with project operation and maintenance (O&M). As is well documented in the literature many developing countries have neglected project O&M which has resulted in a rapid depreciation of past irrigation investments (Carruthers, 1981). Irrigation systems fail to irrigate their planned or projected command areas and after a few years parts of the systems no longer function (Wade, 1975).
