(i) The land use pattern is majorly determined by physical and human factors. The physical factors include topography, climate, soil, and human factors include population density, technology and society and culture. The land use pattern in India is very diverse. Land under permanent pasture has decreased over time. The net sown area also varies from one state to another in India. In Punjab and Haryana, the net sown area is over 80% and in the states of Arunachal Pradesh, Mizoram, Manipur and Andaman and the Nicobar Islands. A part of the land in Indi ais also termed as wasteland which includes rocky land and deserted areas. The land put to non-agricultural uses has also increased over time. However, land under forest cover has not shown any significant growth since 1960-61. It is because the land under agriculture and non-agricultural uses has increased to meet the demands of the growing population.
(ii) The technical and economic development has led to increased consumption of resources in the following ways:
- As production was increased to fulfil the demands of the growing population, more and more resources are exploited.
- Improvement in technology has increased the human capacity to harness natural resources.
