Answer: 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 area due to varied reasons. Out of this 43.41 per cent accounts for net sown, 8.96 per cent is under permanent pastures, grazing land, tree crop and culturable waste land (left uncultivated for more than 5 years), 10.85 per cent constitutes current fallow and other than current fallow, 14.21 per cent land is not available for cultivation because it is barren waste land, or used for non-agricultural use. Forest lands have risen marginally from 18.11 per cent to 22.57 per cent since 1960-61 due to increasing pressure of population on land and rapid industrialisation and urbanisation and infrastructure development activities.
