What human activities contribute to desertification?
The ways people use marginal lands may lead to desertification. Poor farming methods can wear out thin soil, while overgrazing can strip areas of their protective plant cover. Nonnative plants can crowd out native plant species that are better suited to a dry climate. Deforestation can leave marginal lands exposed to erosion.
How might people adapt to living in areas threatened by desertification?
Learning new ways to farm can greatly help reduce desertification. Leaving the land covered in it's natural vegetation will help the land avoid desertification.
