Background
![Page 5: Peter Okoth Annual Program Review 2011 Nairobi, Kenya 9 May 2011 A Globally Integrated Africa Soil Information Service (AfSIS)](https://reader037.vdocuments.mx/reader037/viewer/2022103023/56649e685503460f94b646c4/html5/thumbnails/5.jpg)
Numbers
• About 500 million hectares of sub-Saharan Africa’s agricultural land are moderately or severely degraded
• African farmers are able to apply only 10 percent of the nutrients that farmers in the rest of the world return to the soil
• Soils in southwestern Kenya, for example, lose an estimated 100 kilograms of nitrogen per hectare each year

Nutrient depleted soils reason for poor crops & low productivity

Foreseen Impact
![Page 9: Peter Okoth Annual Program Review 2011 Nairobi, Kenya 9 May 2011 A Globally Integrated Africa Soil Information Service (AfSIS)](https://reader037.vdocuments.mx/reader037/viewer/2022103023/56649e685503460f94b646c4/html5/thumbnails/9.jpg)
Foreseen Impact• Provide accurate & spatially explicit soil database for
42 African countries
• Contribute to the reversal of soil degradation in Africa
• Contribute to increased crop yields & improved livelihoods for approximately 1 to 2 million poor African households
• Prepare material and evidence to guide policy and action that enhances Africa’s soil & crop productivity
• Contribute to the development of African institutions capacity in soil mapping & fertility management
