Item 6: International Center for Biosaline Agriculture

  1. 1. ICBA focuses on carrying high-quality applied research that is critical to increasing food and nutritional security, improving water security, and helping building more resilient environments and income in the marginal environment areas it targets. Since its founding in 1999, ICBA has become a reference and a global Center of Excellence for innovative agriculture in saline and marginal environments. With a team of international scientists, ICBA’s main mission is to work in partnership to deliver agricultural, water and nutrient scarcity solutions in marginal environments.
  2. 2. Marginal agroecosystems
  3. 3. Biophysical constraints •- Soil constraints (texture, low fertility, poor drainage, shallowness, salinity, and sodicity). •- Water constraints (saline and other non- conventional water resources, insufficient water access and quantity). •- Landscape constraints (steep terrain). •- Unfavorable climatic conditions.
  4. 4. Socioeconomic constraints •- Absence of markets, difficult access. •- Restrictive land tenure, smallholdings. •- Poor infrastructure. •- Unfavorable output/input ratios.

  6. 6. Salinization is the accumulation of water-soluble salts in the soil solum (the upper part of a soil profile, including the A and B horizons) or regolith (the layer or mantle of fragmental and unconsolidated rock material, whether residual or transported) to a level that impacts on agricultural production, environmental health, and economic welfare. Salinization Buringh (1979) estimated that the world as a whole is losing at least ten hectare of arable land every minute, five because of soil erosion, three from soil salinization, one from other soil degradation processes and one from non-agricultural uses. Nearly 50 percent of the irrigated land in the arid and semi-arid regions have some degree of soil salinization problems. This figure indicates the magnitude of the problem that must be tackled in order to meet future global food needs.
  7. 7. Salt-affected soils Salt-affected soils occur in all continents and under almost all climatic conditions. Their distribution, however, is relatively more extensive in the arid and semi-arid regions compared to the humid regions. For any long-term solutions, it is, necessary to understand the mode of origin of salt-affected soils and to classify them, keeping in view the physico-chemical characteristics, processes leading to their formation and the likely approaches for their reclamation and successful management.
  8. 8. Salt affected soils distribution Journal of Experimental Botany, Vol. 57, No. 5, pp. 1017–1023, 2006
  9. 9. Classes of soil suitability in regard to salinity A soil is considered saline if the electrical conductivity of its saturation extract (ECe) is above 4 dSm-1 (US Salinity Laboratory Staff, 1954). S0 (Non Saline) S1 (Slightly Saline) S2 (Moderately Saline) S3 (Highly Saline) S4 (Extremely Saline) Soil Salinity Class Ranges
  10. 10. Strategies for saline soils management Management of saline soils Soil reclamation Management of agricultural practices Adaption to saline agriculture • Leaching • Improving soil texture through amandements • Bioremediation • Drainage projects • Transfer soils and excavation • improve fertilization • improve irrigation • Improve drainage • Maintain rootzone with low salt content • Increase soil Organic matter • Cultivate salinity tolerant crops • Breeding of salt tolerance cultivars • halophyte • Accepted economical yield
  11. 11. Topography
  12. 12. Land Use
  13. 13. Objectives The main objectives of the initiative •Improve and develop national capacities on estimating spatial variability of soil salinity •Produce a country-driven global map of soil salinity •Improve national capacities on salt affected soil management
  14. 14. Expected outputs •National soil salinity maps and reports •Global Soil Salinity Map •Global assessment report on salt affected areas •Baseline for soil salinity monitoring
  15. 15. Soil Salinity mapping soil salinity can be mapped on a national scale based on strategies that fit best with the existing data of a given country. Ground truth data is always needed in order to create reliable maps. The prediction of soil salinity can be further improved by taking into consideration other predictive variables, like elevation, meteorological data and the topographic wetness index.
  16. 16. Data Products and Collaboration Levels Option 1 (mandatory): National topsoil salinity and uncertainty maps ( 0-30 cm), created with digital soil mapping and/or remote sensing approaches based on measured electrical conductivity (EC). Option 2 (optional): National topsoil (0-30 cm) pH, ESP and/or SAR maps, created with digital soil mapping based on measured date. Option 3 (optional): National subsoil salinity and uncertainty maps (30-100cm), created with digital soil mapping based on measured electrical conductivity (EC).
