The Sahel
Reducing Desertification
-
-
Organic farming - no fertiliser use, relies on crop rotation and manure
Permaculture - trees provide protection, fields not ploughed, mulch provides nutrients
Desertification
-
Impacts
Environmental - soil erosion, deforestation, less crops grown, less animals raised
Social - migration of people, famine and hunger, malnutrition, pressure on soil
Economic - Reliance on food air, less income in primary sector, less work and wages, poverty
Reducing Soil Erosion
-
Alleviate Soil Erosion
Terracing - sloping lands turn into flat areas, protects soil from sheet erosion and gullying
-
Strip Cropping - different types of crops aligned on contours, creates ridges that forms water break
Permaculture - no fertilizers, trees planted, livestock manure used
Soil Erosion
Causes
-
Population Pressure, Migration
