Land resources in India are primarily divided into agricultural land, forest land, land meant for pasture and grazing, and waste land. ... According to the recent data, about 54% of the total land area is cultivable or fallow, 22.5% is covered by forests, and 3.45% is used for grazing

Land degradation is a global problem largely related to agricultural use, deforestation and Climate Change. Causes include: Land clearance, such as clearcutting and deforestation. Agricultural depletion of soil nutrients through poor farming practices. Livestock including overgrazing and overdrafting.

Answer

Land use involves the management and modification of natural environment or wilderness into built environment such as settlements and semi-natural habitats such as arable fields, pastures, and managed woods.
Land degradation is a process in which the value of the biophysical environment is affected by a combination of human-induced processes acting upon the land. It is viewed as any change or disturbance to the land perceived to be deleterious or undesirable

Answer

Use of land for various purposes is called land utilisation. Under this title are included cultivable land, forest area, fallow land, land for residential purposes, for the construction of roadways, railways, dams, canals, barren land, land used for grazing purposes etc.

Causes include: Land clearance, such as clearcutting and deforestation. Agricultural depletion of soil nutrients through poor farming practices. Livestock including overgrazing and overdrafting.

Answer

Land Utilisation and Causes of Land Degradation
Land Utilisation:
- Land utilisation refers to the extent to which land is used for various purposes such as agriculture, forestry, mining, urbanisation, etc.
- The efficient utilisation of land is essential to meet the growing demands of a growing population.
- Land utilisation can be classified into different categories such as agricultural land, forest land, barren and waste land, etc.
Causes of Land Degradation:
- Overgrazing: When the number of animals grazing on a particular area of land exceeds its carrying capacity, it leads to land degradation.
- Deforestation: The cutting down of trees for various purposes such as agriculture, logging, and urbanisation results in soil erosion and loss of soil fertility.
- Mining: Extractive activities such as mining can lead to land degradation by causing soil erosion, deforestation, and pollution of land and water bodies.
- Urbanisation: Rapid urbanisation results in the conversion of agricultural land into residential and commercial areas, leading to loss of fertile land.
- Industrialisation: Industrial activities generate pollutants that contaminate the soil, water, and air, leading to land degradation.
- Soil erosion: Soil erosion caused by factors such as deforestation, overgrazing, and improper agricultural practices results in the loss of fertile topsoil.
In conclusion, land utilisation and land degradation are closely related concepts that have a significant impact on the environment and human livelihoods. It is essential to adopt sustainable land management practices to ensure the long-term productivity and health of the land.
