- Abstract:
- Across Sub-Saharan Africa (SSA) agriculture is a dominant sector in the economies of most countries accounting for between 30 to 40 percent of gross domestic product, and the sector is a leading source of jobs for over two-thirds of Africa’s population. And yet, though it has the potential to be an agricultural power, a combination of low productivity and an inadequate policy framework make SSA the world’s most food-insecure region. Over the last 40 years it has also been steadily losing its share of the global agricultural market. With less than 10% of SSA’s population, Thailand exports more food products than all SSA countries combined, and Brazil’s food exports are now 150% higher than those of SSA, although levels were similar in the 1980s. The “Green Revolution” that transformed tropical agriculture in Asia and Latin America largely bypassed Africa, with total factor productivity growth in agriculture lagging behind that of other regions in the world (Evenson and Gollin 2003) 1 . Two main factors are responsible. First, little land on the continent is irrigated. Only two percent of Africa’s renewable water resources are used, compared to a global average of five percent. Of the 183 million hectares of cultivated land in SSA, 95 percent is rain-fed and less than 5 percent benefits from some sort of agricultural water management practice—by far the lowest irrigation development rate of any region in the world. Moreover, of the 7.1 million hectares equipped with irrigation equipment, only 5.3 million are currently operational. Second, modern inputs and technological processes are grossly underutilized. Africa has, by far, the lowest rate of improved seed and fertilizer use of any region— a rate that has remained virtually constant for the last 40 years—and the lowest level of mechanization in the world. In consequence, African farmers have the lowest farm productivity; their grain yields only one-half of those achieved by Asian or Latin American farmers.
