Question

Which of the following factors contribute to land degradation in India?

Options

  • Soil Erosion

  • Alkalinity and Salinity of Soil

  • Deforestation

  • All of the above

MCQ

Solution

All of the above

Explanation:

The following are some of the causes that contribute to India's land degradation:

  1. Soil Erosion:
    Soil erosion is defined as the removal of the top layer of soil caused by strong winds or floods. Major nutrients such as nitrogen, phosphorus, and potassium are carried in this top layer of the soil and are necessary for plant growth. As a result, the loss of this layer diminishes the land's productivity.
  2. Alkalinity and Salinity of Soil:
    The problem of water plugging is what causes the salinity and alkalinity. The water stuck on the top layer of soil consumes all of the nutrients in the soil, causing the land's fertility to deteriorate.
  3. Deforestation:
    The ever-increasing population, together with their ever-increasing demand, results in widespread forest degradation. By limiting the amount of oxygen in the air, the reduction of forest cover has an impact on the ecological balance. As a result, pollution levels rise, posing a variety of health risks.
  4. Shifting Cultivation:
    Shifting cultivation, combined with subsistence farming practiced by small and marginal farmers, resulted in soil nitrogen and fertility replenishment.
