10. Explain the land use pattern in India and why has the land under forest not increased much since 1960-1961?
Ans.
(i) Total geographical area of India is 3.28 million sq km, however, is available only for 93 per cent of the total geographical area because the land use reporting for most of the north-east states except Assam has not been done fully. Moreover, some areas of Jammu and Kashmir occupied by Pakistan and China have also not been surveyed.
(ii) Most of the other than the current fallow lands are either of poor quality or the cost of cultivation of such land is very high. Hence, these lands are cultivated once or twice in about two to three years and if these are included in the net sown area then the percentage of NSA in India comes to about 54 per cent of the total reporting area. The pattern of net sown area varies greatly from one state to another. It is over 80 per cent of the total area in Punjab and Haryana and less than 10 per cent in Arunachal Pradesh, Mizoram, Manipur and Andaman Nicobar Islands.
(iii)It was considered essential for maintenance of the ecological balance. The livelihood of millions of people who live on the fringes of these forests depends upon it.
11. How have technical and economic development led to more consumption of resources? Ans. Economic development creates demand for various resources and technical development gives the knowhow to exploit those resources. Thus, technical and economic development; together lead to more consumption of resources
