Presentation by Peter Okoth for the CIAT KSW 2009

3. Background

5. Nutrient depleted soils reason for poor crops & low productivity

6. Large scale land degradation due to soil erosion: How to address?

7. Impact

9. The Sahelian Drylands Area: 1.2 million km 2 Population: 38 million Millet & sorghum belt: 23 million ha Initial Impact zones targeted by AfSIS Nigeria Kenya Malawi Tanzania Mali Humid Forest Zone Area: 5.8 million km 2 Population: 168 million Cassava belt: 18 million ha NERICA potential: 2 million ha Moist Savanna and Woodland Zones Area: 4.4 million km 2 Population: 157 million Maize belt: 32 million ha CA potential: 7 million ha S N E W 0 1000 2000 kilometers
