    In Africa, agriculture is the most important sector in national economies. About 80 per cent of the active population works in agriculture. Further, apart from few exceptions, agriculture makes up more than 50 percent of gross national product. Nevertheless, Africa remains the only region in the world in which agricultural production declined between 1970 and 1980, when the growth rate was less than 2 per cent and moreover the gross national product (GNP) per head is one of the lowest in the world.

Widespread desertification and degradation of African farmlands and the present heavy dependence on natural rainfall which are some of the causes of low productivity, reflect the inability of African member States to sufficiently invest in and develop technologies and farming systems suitable for adoption by small farmers.

    20 years is of the gravest concern to African governments as well as to the international community. Food production is not able to keep pace with population growth and many countries in the continent have become increasingly dependent on imports of food stuffs originating from international aid.
