REDUCING RISK OF DESERTIFICATION

HideShow resource information
Water management
- Gorwing crops that dont need much water (e.g. millet, sorghum or olives) can reduce water use. - Using drip irrigation on crops instead of surface irrigation means that the soil isnt eroded by lots of water being added in one go.

Tree planting
-Trees act as windbreaks to protect soil from wind erosion.-Trees can also stabilise sand to prevent desert from encroaching on farm land.-Growing trees in amongst crops protects crops (and soil) by providing shade.

Soil management
-Leaving areas of land to rest in between grazing or planting lets them recover their nutrients.-Rotating crops that use different nutrients from the soil means that the same nutrients dont keep being removed.-Compost used to add nutrients to soil.
3 of 5
Appropriate technology
-Using cheap, sustainable+easily available materials that are easy for local to maintain.-E.g. sand fences (to trap windblown sand) or terraces constructed to stabilise soil and reduce erosion.-Deforestation reduced by using solar cookers for cooking
