The prevention and mitigation of famine: policy lessons from Botswana and Sudan.
Botswana and Sudan experienced consecutive years of drought in the 1980s. Sudan faced a large decline in food entitlement and nutritional deterioration, which translated into famine in 1984/85. Botswana, on the other hand, nearly compensated income losses and averted nutritional deterioration and famine-related deaths....
