Answer Details
Desert encroachment refers to the gradual expansion of arid or desert areas into previously habitable lands due to human activities or climate change. The best way to control desert encroachment is to plant trees, which is known as afforestation. Trees help to stabilize soil, retain moisture, and prevent wind erosion, thus helping to maintain the fertility of the land. This can be achieved by planting trees in strategic locations or through reforestation programs. Erecting barriers, deforestation, overgrazing, and slopewise cultivation can have negative impacts on the environment and may exacerbate desert encroachment in the long run.
