The agricultural sector of African economies has faced considerable challenges within the past 50 years or so. Although agricultural production on the continent rose by an annual average of 2% between 1965 and 1980 and has continued to increase by 1.8% annually since then, population growth of 2.9% per year has resulted in a per capita decline in agricultural production. From self-sufficiency i...
