Methods Of Combatting Rural Land Degradation Flashcards
Small scale irrigation schemes
Brings water security to areas
Ensures vegetation does not die
Encourages natural vegetation to grow
Native species reintroduced
Large scale dams
Ensure regular water supply
Expensive and environmental consequences
Crop rotation
Ensures that the same nutrients are not always taken from the soil
Allows soil recovery
Maintains vegetation cover
Wind shields
Trees planted in lines perpendicular to the prevailing wind
Protects against desertification
Prevents the wind from blowing away the nutrient rich top soil
Drought resistant shrubs and plants
Successful in areas such as the Sahel in Africa North of the equator with little rainfall or water access
Plant roots bind soil and prevent erosion by rain
Animal fences
Moved around to control grazing and trampling of ground by animals which compacts the ground
Leads to higher rates of erosion
Stone Lines
Can be placed at the bottom of slopes and when overland/surface flow moves sediment is trapped
Locals rake this material back over the source area in order to minimise land degradation
