• Over farming and overgrazing on marginal lands • Extended droughts in the Sahel region • Wind erosion of topsoil These situations have all contributed to (1) population growth in Southwest Asia (2) deforestation in South America (3) desertification in sub-Saharan Africa (4) increased reliance on fossil fuels in Asia

Respuesta :

The Sahel is located on the African continent between the Atlantic Ocean and the Red Sea. Because of its long periods of scarcity of rain and semi-arid pasture, land desertification generates in this area.


The agriculture, overgrazing, overpopulation of marginal lands and soil erosion contribute to deep desertification in the region.
