Soil for Africa - the role of sustainable soil management for restoration of degraded land in East Africa and the Sahel - Winowiecki

  1. 1. Soil for Africa: The role of sustainable soil management for restoration of degraded land in East Africa and the Sahel Leigh Winowiecki, ICRAF, Nairobi, Kenya
  2. 2. 2 Key indicators of land degradation: – Soil erosion prevalence – Root depth restriction – Soil fertility status Predictive maps of root depth restriction across SSA illustrates land degradation hotspots (in red) (Vågen et al., 2016) http://dx.doi.org/10.1016/j.geoder ma.2015.06.023 Land degradation in the drylands of SSA continues to threaten food security and livelihoods
  3. 3. Tools: Using Soil Information to Target Land Restoration Interventions Maps of soil organic carbon (left) and soil erosion prevalence (right) based on field surveys + remote sensing in Kenya Source: ICRAF GeoScience Lab
  4. 4. Approach: Research in Development Partnerships 10/05/2017 ESA Regional Implementation Workshop Kampala, Uganda – 22nd – 25th May 2017 6
  5. 5. 10/05/2017 7 Approach: Implementing & monitoring on- farm land restoration interventions with development partners

  7. 7. Example: Maize in planting basins within Agroforestry Systems in Kenya
  8. 8. www.worldagroforestry.org Whatisagroforestry? The inclusion of trees in farming systems and their management in rural landscapes to enhance productivity, profitability, diversity and ecosystem sustainability
  9. 9. Real time monitoring of the performance of the land restoration options to inform investments
  10. 10. Sustainable soil management is the key to restoration of degraded land!
