Question

What are the steps than lead to desertification at a place

Answer 1

Answer: Desertification is the process of conversion of fertile lands into arid regions or deserts. It leads to loss of biological diversity and occurs due to natural processes or human exploitation. Following are the steps that could lead to desertification at a place.

Explanation: Human activities:

• Urbanisation: Due to extensive urbanisation at a particular place the space for the tress to grow reduces. Extensive urbanisation also calls for the development of a number of concrete buildings which further leads to desertification.
• Deforestation: Cutting down trees for commercial purposes without planting new ones leads to extensive soil erosion which in turn converts the fertile land into arid regions.
• Animal Grazing: Clearing of forests to grow grasslands which serves as the fooder for the cattle accelerates the process of desertification.

Natural processes

• A Decline in rainfall: A decline in rainfall can turn the soil dry which causes the land to become arid.
• Global warming: Due to gradual increase in temperature the climate of particular areas changes making it difficult for the local vegetation to survive thereby gradually causing desertification.

Answer 2

Answer:

human activities that contribute to desertification include the expansion and intensive use of agricultural land, poor irrigation practices, deforestation, and overgrazing. these unsustainable land uses place enormous pressure on the land by altering it's soil chemistry and hydrology
