Severe Drought
Long Rainless Periods: Crop Failures, Dry Soils
Rapid Population Growth More trees cut: Fuel and Housing Overgrazing: Sheep, Goat, Cattle eating the Veg Over-Cultivated Land: loss of fertility
As a result: Bare and Exposed Soil – Unsuitable for Vegetation

(in the Sahel region)

Increase the amount of grazing land available Restrict the number of cattle, sheep and goats
which graze in semi-desert regions Drought-resistant grass and trees being
planted! Roots also help bind the soil together to prevent being blown away in wind
Irrigation: A Solution?
