Explain land use pattern in India and why has the land under forest not
increased much since 1960-61?
Explain land use pattern in India and why has the land under forest not
increased much since 1960-61?
ANSWER:-
Land resources in India are primarily divided into agricultural land, forest land, land meant for pasture and grazing, and waste land. Waste
land includes rocky, arid and desert areas, and land used for other non-agricultural purposes such as housing, roads and industry.
The total geographical area of India is 3.28 million sq km. As per the land use
data only 93% of the total geographical area is available. Of this 43.4% is the
net shown area, forest cover is 22.6%, 4.4% is culturable waste, 7.03% is
current fallow, 4% is covered by pastures and 1% is covered by tree crops.
The land under forest has not increased since 1960–61 because in the post- independence
era demand for more land to expand agriculture,
mainly after Green Revolution, developmental works
and infrastructural facilities, led to clearance of forests areas.
Industrialisation and urbanisation also decreased the forest area. Thus, land
under forest has increased by only about 4% since 1960-61.
