Q50: Discuss the factors responsible for land degradation in India.  (2015,2014)

Class 10 Social Science Previous Year Questions - Resources and Development  View Answer

Ans: The important factors responsible for land degradation in India are as follows:
(i) Deforestation: By an estimate over one million hectares of forest is lost every year in India.
(ii) Erosion: Loss of vegetation cover makes land more susceptible to erosion. Wind and water have left vast tracts of land barren. Water erodes top soil to an extent of around 12,000 million tons per annum
(iii) Over-irrigation : Successive cropping and overirrigation, leads to water-logging and consequent salinisation and alkalisation. This situation mainly arises due to poor drainage.
(iv) Floods and Droughts : Drought is both man-made and environment-induced. Man has played a key role in the creation of drought-prone areas by over-exploitation of natural resources like forests, degradation by grazing, excessive withdrawal of ground water, silting of tanks, rivers, etc. Floods, on the other hand, are caused by heavy rains in a very short period. Each situation could have been altered had there been good vegetation cover. Vegetation helps in reducing run-off, increasing infiltration and reducing soil erosion.
(v) Over-grazing : India has the worlds largest cattle population, but not enough pasture land. This has led to serious problems as animals have encroached into forest lands and even agricultural lands. Land degradation due to over-grazing leads to desert like conditions.
(vi) Pollution : Pollution of land is caused by disposal of solid waste, leftover from domestic, industrial and agricultural sectors. Another major source of land pollution is the creation of derelict land due to mining particularly due to surface and underground mining activities.


Q51: Consequences of environmental degradation do not respect national or state boundaries. Support the statements with examples.    (CBSE 2015)
