FERTILIZER IN SUB-SAHARAN AFRICA: Breaking the Vicious Circle of High Prices and Low Demand
نویسنده
چکیده
Fertilizer is a powerful productivity-enhancing input, but SSA uses very little. Historical trends are abysmal (Figure 1). In 1970, SSA used <5kg/ha while other developing regions used >15 kg/ha. In the 25 years from 1970 to 1995 fertilizer consumption grew only .23 kg/ha/year. Current use is only 9 kg/ha, down from OBJECTIVES AND METHODS: The research highs of 11-12. This contrasts sharply with >50 kg/ha used in Latin America and >80 kg/ha in Asia.
