Continuous use of land over a prolonged period of time without taking necessary steps to conserve and manage it, has resulted in land degradation.
Four human activities responsible for land degradation in India are as follows :
(i) In states like Jharkhand, Chhattisgarh, Madhya Pradesh and Orissa deforestation due to mining have caused severe land degradation. Mining sites are dug, drilled or quarried and abondoned after excavation work is over, leaving the landover burdened and in a highly degraded state.
(ii) Mineral processing like grinding of limestone for cement industry and calcite and soapstone for ceramic industry generate huge quality of mineral dust in the atmosphere which ultimately settles down on the land. It retards the process of infiltration of water into the soil, thus, degrading the land. Discharge of industrial effluents and wastes cause pollution and land degradation in industrial regions.
(iii) In states like Gujarat, Rajasthan, Madhya Pradesh and Maharashtra overgrazing is one of the main reasons for land degradation.
(iv) In Punjab, Haryana and Western Uttar Pradesh over-irrigation is responsible for land degradation. It leads to water logging which in turn increases salinity and alkalinity in the soil and reduces its fertility.

Explanation:
The three human activities responsible for the land degradation in India are :
1. Deforestation : The cutting of tress by the people in India is one of the reasons of land degradation. It leads to the erosion of land and desertification and thus the land becomes waste or less fertile.
2. Over-Irrigation : This human activity also leads to land degradation. Over-Irrigation leads to water-logging and consequentially salinisation and alkalinisation of soli.
3. Land Pollution : The people in India dispose improperly their home wastes and industrial wastes and effluents which made the land waste and less fertile.
