  2. 2. SOILS ARE IMPORTANT! - Basis for the provision of food, fibre, fuel and medicinal products. - Stores and releases water, both for plant grow and water supply. - Greatest pool of soil organic carbon. - Regulates carbon, oxygen and plant nutrient cycles (N, P, K, Ca, Mg, etc). - Sustains biological activity, diversity and productivity. - Habitat for seeds dispersion and dissemination of the gene pool. - Central role in buffering, filtering and moderation of the hydrological cycle. - Platform for urban settlement and as material for construction.
  3. 3. Land degradation affects soil health • • • • • • Soil erosion (wind/water) Soil salinity/sodicity Nutrient depletion Loss of organic matter Soil compaction Soil sealing, etc
  4. 4. CHALLENGES AHEAD FOR SOILS +60% Population growth Globally increase on food production and also ecosystem services…….. Further Pressure on for
  5. 5. GLOBAL SOIL PARTNERSHIP Pillars of Action Promote sustainable management of soil resources and improved global governance for soil protection and sustainable productivity.    Soil management Soil conservation Soil restoration/rehabilitation
  6. 6. TOWARDS SUSTAINABLE SOIL MANAGEMENT Improving soil water storage PRINCIPLES FOR SUSTAINABLE SOIL MANAGEMENT IN A CHANGING CLIMATE Controlling soil erosion Assessing the status of soils and its properties Improving soil structure with organic matter Managing soil organic matter for soil carbon sequestration Boosting nutrient management
