Key concerns in Africa are: 1) recurrent famine due to uncertain rainfall patterns, 2) poor crop yield resulting from low soil fertility and 3) poverty. Examples of climate-induced problems in some African countries namely Niger, The Gambia, Cameroon, Mali, Senegal, Ghana and Rwanda are cited. Research data show that the impact of weather variability on crop yield can be mitigated. People, livestock, and plants live and die on the planet and atmospheric CO2 and greenhouse gases continue to rise, regardless of location. Farmer-affordable technologies to mitigate effects of these problems have...
