Transcript

  • 1. Assessing SLM strategies at field scale Runoff and sediment collector tanks in a no-tillage field experiment, Chile
  • 2. Tests of SLM strategies at field scale have a large demonstrative power, due to the recognizability for local stakeholders
  • 3. Testing in 3 phases Implementation Monitoring Evaluation
  • 4. Preparation for transport of seed for planting of vegetative barriers. Cape Verde. INIDA ©
    • Installation of technologies in the field
    • Sometimes in collaboration with stakeholders
    Implementation
  • 5. Scientists listing agronomic activities together with the land user. Tunisia. IRA-Médénine ©
    • Biophysical variables (e.g. soil moisture)
    • Agronomic activities and yield assessment in collaboration with stakeholders
    • 1-3 growing seasons
    Monitoring
  • 6. Preparation for transport of seed for planting of vegetative barriers. Cape Verde.
    • Scientific analysis of technology versus reference plot
    • Production impacts, socio-economic impacts and ecological impacts using the WOCAT QT questionnaire
    • Comparison of yield and crop quality data between experiements
    Evaluation
  • 7. 22 SLM technologies tested in 57 field experiments in 16 countries
  • 8.  
  • 9.  
  • 10. Reduced ploughing with disc-plough to twice instead of 3-5 times per year to maintain soil structure, increase organic matter content and reduce erosion Reduced tillage (dryland cereals, Guadelentin, Spain)
  • 11. A crop grown to be ploughed into the ground to increase organic matter content, thereby improving fertility and reducing erodibility Green manure (dryland almond, Guadelentin, Spain)
  • 12. Spreading of organic (or other) materials on the surface of the soil to reduce moisture loss, reduce erosion, inhibit weed growth Straw mulch (dryland almond, Guadelentin, Spain)
  • 13. Collection and concentration of rainfall to make it available for agricultural or domestic uses in dry areas where moisture deficit is the primary limiting factor Traditional water harvesting (Boqueras) (dryland almond, Guadelentin, Spain)
  • 14. Controlled burn to reduce fuel build-up and decrease the likelihood of serious hotter fires Prescribed fire (extensive grazing, Góis, Portugal)
  • 15. Strategic management of fuel load and fuel strips, like primary strip networks Preventive forestry (forest, Maçao, Portugal)
  • 16. Seeding crops without disturbing the soil through tillage, involving one pass during which a part of the soil surface is “opened” and the seeds are placed concurrently No-tillage (olive, Crete, Greece)
  • 17. Land closed by fencing (or other means) for control of grazing or resting during a specified period to reconstitute its plant cover Controlled grazing (grazing land, Crete, Greece)
  • 18. Transport and use of non-salted freshwater for irrigation Transport of freshwater from local streams (arable cropping, Nestos, Greece)
  • 19. Alteration of strips of crops and fallow perpendicular to wind Strip cropping (arable cropping, Karapinar, Turkey)
  • 20. Seeding crops without disturbing the soil through tillage, involving one pass during which a part of the soil surface is “opened” and the seeds are placed concurrently Zero tillage (arable cropping, Karapinar, Turkey)
  • 21. Spreading of organic (or other) materials on the surface of the soil to reduce moisture loss, reduce erosion, inhibit weed growth Mulching (arable cropping, Karapinar, Turkey)
  • 22. Structural barriers along the contour to trap sediments and reduce runoff velocity Sediment fences (barley, Eskesehir, Turkey)
  • 23. Rehabilitation of gullies with cross-slope barriers for reducing runoff velocity and soil erosion V-notch to measure catchment runoff Atriplex plantation in gullies Gully treatment (grazing, Sehoul, Morocco)
  • 24. Spreading of organic (or other) materials on the surface of the soil to reduce moisture loss, reduce erosion, inhibit weed growth Mulching and minimum tillage (cereals-leguminous rotation, Sehoul, Morocco)
  • 25. Collection and concentration of rainfall to make it available for agricultural or domestic uses in dry areas where moisture deficit is the primary limiting factor. Tabia and jessour (olive, grazing, Tunisia)
  • 26. Binding cages filled with stones together to form a dam to slow down runoff and enhance infiltration Gabion check dams (olive, grazing, Tunisia)
  • 27. Land closed by fencing (or other means) for control of grazing or resting during a specified period to reconstitute its plant cover Rangeland resting (grazing, Tunisia)
  • 28. Land closed by fencing (or other means) for control of grazing or resting during a specified period to reconstitute its plant cover Rangeland resting (grazing, Tunisia)
  • 29. Enhanced infiltration of runoff water to the aquifer to recharge groundwater and wells Recharge well (olive, grazing, Tunisia)
  • 30. Irrigation method which saves water and fertilizer by allowing water to drip slowly to the roots of plants, either onto the soil surface or directly onto the root zone, through a network of valves, pipes, tubing, and emitters. Drip irrigation (vegetables, Russia)
  • 31. Collection and concentration of rainfall to make it available for agricultural or domestic uses in dry areas where moisture deficit is the primary limiting factor Snow melt water harvesting (vegetables, Dzhanybek, Russia)
  • 32. Technical improvement of irrigation to reduce water use Improved sprinkler irrigation (cereals-fodder, Novij, Russia)
  • 33. Spreading of organic (or other) materials on the surface of the soil to reduce moisture loss, reduce erosion, inhibit weed growth Residue mulching (maize-millet, Yan River Basin, China)
  • 34. Ditches along the contour to slow down runoff and allow infiltration Infiltration contour ditch (orchard, China)
  • 35. Gas produced by the biological breakdown of organic matter in the absence of oxygen Biogas (grazing, Botswana)
  • 36. Combines minimum soil disturbance, permanent soil cover, and crop rotation Mulching, minimum tillage & crop residues (annual cropping, Mexico)
  • 37. Seeding crops without disturbing the soil through tillage, involving one pass during which a part of the soil surface is “opened” and the seeds are placed concurrently No tillage machine No tillage (annual cropping, Chile)
  • 38. Integrates the use of woody perennials with agricultural crops for a variety of benefits Agroforestry (maize-beans, Cape Verde)
  • 39. Planted perennial obstacles along the contour to trap sediments and reduce runoff velocity Vegative barriers (maize-beans, Cape Verde)
