Detailed explanation-1: -desertification, also called desertization, the process by which natural or human causes reduce the biological productivity of drylands (arid and semiarid lands).

Detailed explanation-2: -Desertification reduces the land’s resilience to natural climate variability. Soil, vegetation, freshwater supplies, and other dry-land resources tend to be resilient. They can eventually recover from climatic disturbances, such as drought, and even from human-induced impacts, such as overgrazing.

Detailed explanation-3: -Desertification is any widespread environmental degradation that reduces productivity of dryland ecosystems by reducing plant cover, soil loss, loss of soil organic matter, increasing sand dunes, and increasing run-off.

Detailed explanation-4: -Desertification includes land degradation in arid, semi-arid and dry sub humid areas resulting from various factors, including climatic variations and human activities.
