A:- The use of land is determined both by physical factors such as topography, climate, soil types as well as human factors such as population density, technological capability and culture and traditions etc. Total geographical area of India is 3.28 million sq km. Land use data, however, is available only for 93 per cent of the total geographical area because the land use reporting for most of the northeast states except Assam has not been done fully. Moreover, some areas of Jammu and Kashmir occupied by Pakistan and China have also not been surveyed. The pattern of net sown area varies greatly from one state to another. It is over 80 percent of the total area in Punjab and Haryana and less than 10 per cent in Arunachal Pradesh, Mizoram, Manipur and Andaman Nicobar Islands. Forest area in the country is far lower than the desired 33 per cent of geographical area, as it was outlined in the National Forest Policy (1952). It was considered essential for maintenance of the ecological balance. A part of the land is termed as wasteland and land put to other non agricultural uses . Waste land includes rocky, arid and desert areas and land put to other non-agricultural uses includes settlements, roads, railways, industry etc. Continuous use of land over a long period of time without taking appropriate measures to conserve and manage it, has resulted in land degradation.

Resources are vital for any developmental activity. But irrational consumption and overutilisation of resources may lead to socio-economic and environmental problems. But more economic development makes more the greedy mentality and selfish individuals and exploitative nature of modern technology as the root cause for resource depletion at the global level. Economic and technological development increase the irrational consumption and over-utilisation of resources. In that way economic development and technological development increases the depletion rate of land.
