Answer the following questions in about 120 words.
(i) Explain land use pattern in India and why has the land under forest not increased much since 1960-61?
(ii) How have technical and economic development led to more consumption of resources?
i) Land used by humans is known as land use. In India, land is mainly divided into agricultural land, forest land, pasture land, grazing land and waste land. Waste and barren lands are not used for cultivation purposes. Besides cultivation, lands are also used for non agricultural purposes like construction of roads, buildings and factories etc.
In India, 22.5% of the land is under the forest cover. The land under net sown area is 45.24%. While 3.38% of land are permanent pastures and used for grazing, 12.01% of the total land is unculturable waste lands.
Land under forest has not increased since 1960-61 due to deforestation, mining activities, quarrying, building of large dams and highways.
(ii) During the colonial era, imperial powers used their technological and military superiority to colonise the weaker nations. After colonizing them, they gained greater access to the country’s natural resources.
At present, advancement in technology has led to large scale production leading to over utilisation of resources. In India, technological advancement has led to greater exploitation and consumption of resources. Further, increase in the population of the country due to improved medical and health facilities has led to rapid consumption of the resources.
