What are the causes of desertification in India?

Loss of Soil Cover: Loss of soil cover, mainly due to rainfall and surface runoff, is one of the biggest reasons for desertification.

  • Vegetation Degradation:
  • Water Erosion:
  • Wind Erosion:
  • Climate Change:

    • How is desertification caused by deforestation?

    Trees prevent soil erosion and play a pivotal role in the water cycle by absorbing water in the ground and returning water vapor back to the atmosphere. If trees are removed, the area can become much warmer and drier, which may result in desertification, which is a transformation of once fertile land into desert.

    Which part of India is greatly affected by desertification?

    In eight states—Rajasthan, Delhi, Goa, Maharashtra, Jharkhand, Nagaland, Tripura and Himachal Pradesh—around 40 to 70 per cent of land has undergone desertification. There is more to it, as 26 of 29 Indian states have reported an increase in the area undergoing desertification in the past 10 years.

    Is there desertification in India?

    Cultivated lands in India are in the grips of desertification. The country’s Green Revolution pockets are especially prone to the problem. The biggest threat of desertification emanates from the major crops of the Green Revolution — wheat and paddy.

    What are the causes of deforestation in India?

    Farming, cutting of timber, mining and often indiscriminate dam building for hydro electric power projects are the foremost causes of deforestation in India. Another factor is the burgeoning population and its resultant growing urbanisation.

    How does climate change affect the process of desertification of India?

    CLIMATE CHANGE MAY have brought down rainfall over the years, but it has increased the intensity of rain. The IPCC report shows a three-fold increase in extreme rain events in central India during 1950-2015. This has influenced several land degradation processes, including soil erosion.

    Is there deforestation in India?

    In the absence of policies that regulate how imported palm oil or timber is produced, India is a contributor to large-scale deforestation in these countries.

    Which Indian state has the highest degraded land?

    While Rajasthan is understandably the most degraded state, owing to its natural climate and soil systems, it is followed by Maharashtra and Gujarat.

    How much of India’s land is degraded?

    Currently, 97.85 million hectares (mha) of land — an area 2.5 times the size of India’s largest state Rajasthan— has already been degraded. Of this, 3.32 mha — an area 22 times the size of Delhi — has been added in the 15 years between 2003-05 and 2018-19.

    What are causes of desertification?

    ‘Climatic variations’ and ‘Human activities’ can be regarded as the two main causes of desertification. Climatic variations: Climate change, drought, moisture loss on a. global level. Human activities: These include overgrazing, deforestation and.
