Sub-Saharan Africa has more than 50 percent of the world’s potential for land cultivation. Yet, most of this land is in poor condition and unable to satisfy the needs of agricultural production. The Africa Soil Information Services project helps meet these needs with a gridded Soil Information System of Africa and soil nutrient maps.
Poor soil health is recognized as a major cause of decline in agricultural productivity in sub-Saharan Africa. This low cost soil and plant analysis technology works to improve management of natural resources through light photon based methods.
Soil erosion and land degradation are major causes of smallholder vulnerability, reducing crop productivity and increasing food security. This soil information system is an extensive compilation of up-to-date soil fertility data, providing soil fertility maps and fertilizer recommendations.
A business model approach to assessing the feasibility and encouraging investment in smallholder solar pump irrigation. In doing so, these proposed business model frameworks identify promising investment opportunities that can increase the sustainability of agricultural water management technologies.
By creating bunds and dykes on the edges of hydropower reservoirs, water can be retained in the draw down period to create artificial wetlands and fisheries, mitigating some potential negative impacts of hydropower development.
There are valuable resources trapped in city waste, including nutrients for soils, water for irrigation, and energy for household use. By creating business models for recovering and reusing these resources, we can help pave the way for reduced pollution and more sustainable food and energy systems.
