To solve the problems caused by desertification means increase the amount of food that can be grown in areas where people live and farm the land. The following problems can be tackled by
- Deforestation - Aforestation, that is re-planting trees, especially in shelter belts. Planting grasses can help stabilise the soil and cut down on erosion by wind and rain.
- Overcultivation - Using good farming practices such as proper crop rotation and the use of manure as a fertiliser
- Overgrazing - It is important that the young trees are fenced off to prevent grazing by animals
- Poor irrigation - Make sure the water is not evaporated on the surface which wastes water and increases its salinity
- Drought - This can be triggered by deforestation, so aforestation should help reduce this. Also terracing the land to slow down the water running off will make better use of the rain that does fall
Most of all desertification can be controlled by human activity. This is by people not
mis-using the land and by reducing the pressure of too many people living in an area.
