Management of Natural Resources

Question:

Explain why, despite good rains, we are not able to meet the demand for water of all the people in our country.

Answer:

Despite good rains, we are not able to meet the demand for water of all people because:

  1. Our population is increasing rapidly.
  2. Due to lack of sufficient vegetation cover on ground, only a little rain water seeps into the ground and get stored as ground water.
  3. The high yielding varieties of crops require much more water for irrigation.
  4. Discharge of untreated sewage and industrial waste into water bodies.
