What are 3 causes of desertification?
Human activities that contribute to desertification include the expansion and intensive use of agricultural lands, poor irrigation practices, deforestation, and overgrazing . These unsustainable land uses place enormous pressure on the land by altering its soil chemistry and hydrology.
What are the negative effects of desertification?
Land degradation and desertification can affect human health through complex pathways. As land is degraded and deserts expand in some places, food production is reduced , water sources dry up and populations are pressured to move to more hospitable areas.
Are deserts growing or shrinking?
