Fig. 1. A complex, interlinked network of factors operate to perpetuate poverty in much of the developing world, including sub-Saharan Africa. Literally dozens of economic, political, and social factors can be identified as contributing to a causal web that effectively serves to lock in poverty, poor governance, and undernutrition. Many of these factors are bi-directional, such as the relationship between poor governance, chronic disease, and poverty. Successful implementation of the Green Revolution appears to be an important factor that could alleviate much of the poverty in sub-Saharan Africa. However, a plethora of factors (some of which are global) inhibit this. The figure attempts to convey the as yet undelivered promise of the Green Revolution as lightning flashes that try, but ultimately fail, to connect (and thus alleviate) governance and soil nutrient depletion.
