Question 3:
(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?

Answer 3:
(i)Land resources in India are primarily divided into agricultural land, forest land, pasture and grazing land, and wasteland. Wasteland includes rocky, arid and desert areas and land used for non-agricultural purposes like housing, roads, industry, etc.

According to recent data available, the percentage of net sown area (NSA) in India is about 54% of the total reporting area (if, the other than current fallow lands is included). . 22.5% is covered by forests, and 3.45% is used for grazing. The rest is a wasteland, with traces of miscellaneous cultivation.

Improper use of forest land has led to land degradation and made conservation of forests difficult. Human activities like deforestation, overgrazing, mining, quarrying, etc have contributed to the slow growth rate of forests. Thus, land under forest has increased by only about 4% since 1960-61.

(ii)The following factors have been responsible for technical and economic development leading to overconsumption of resources.

In colonial times, imperial powers used their technological and economic superiority to establish control over other countries and thereby gain access to the latter’s resources. One country’s resources were accessible to the citizens of its colonial ruler too, leading to increased consumption. Technical progress also results in inefficient machinery, increased production, and greater consumption of resources.

Technological development and economic progress have led to populations increasing due to low mortality at all ages. With new developments in medicine and health care, fewer people die due to accidents, diseases, childbirth, etc. This too has contributed to higher consumption of resources.
