Desert
Definition: desert
desert: An area of land with very little rainfall, arid soil, and little or no vegetation. COMMENT: A desert will be formed in areas where rainfall is less than 25 cm per annum whether the region is hot or cold. About 30% of all the land surface of the Earth is desert or in the process of becoming desert. The spread of desert conditions in arid and semi-arid regions is caused not only by climatic conditions but also by human pressures. So overgrazing of pasture and the clearing of forest for fuel and for cultivation both lead to the loss of organic material, a reduction in rainfall by evaporation, and soil erosion. Understanding desert environments and the factors contributing to desertification is important for sustainable land management. Farmers should implement practices like agroforestry, soil conservation, and water management to combat desertification and improve land productivity. Exploring sustainable agricultural practices in arid regions can enhance resilience and food security.
