Question

Give a geographical reason for the following:

Long rooted trees and sand holding grasses are grown bordering fields near deserts.

Answer 1

Long-rooted trees and sand-holding grasses are grown bordering fields near deserts to halt the advance of migratory sand dunes. Sand dunes, especially in desert areas, are constantly moving due to the wind, and this can bury fertile land, agricultural fields, and even villages. By planting long-rooted trees and sand-holding grasses, the vegetation stabilizes the sand and prevents it from shifting further. This helps to protect the land from being devastated by the movement of the dunes and ensures that the fertile soil remains intact for farming. This method of sand dune control is especially useful in desert regions like the Sahara and the Thar Desert.
