Status of Crop Biotechnology in Africa
Agriculture contributes over 25% of GDP and employs above 70% of the labor force in most African countries’ economies (UNECA, 2009). Agricultural productivity is constrained by a many factors including abiotic and biotic stresses. The challenge is to develop technologies that can overcome these limiting factors and can be utilized by small-scale farmers who use minimal external inputs. Such technologies can include use of biotechnology products.
In Africa, biotechnology tools used in agriculture include tissue culture, molecular characterization, marker assisted selection, molecular diagnostics, and genetic modification (GM). Currently tissue culture is applied in many countries for rapid multiplication of planting materials for vegetatively propagated crops such as coffee, banana, pineapple, and root crops. However, few countries have adopted GM for crop production improvement, and for agricultural research and development (Table 1).

The GM crops that are under commercial production in Africa are cotton (South Africa, Sudan and Burkina Faso), maize (South Africa) and soybean (South Africa) (James, 2014) while various crops and traits are under research and development (Table 2).
