Water Resources

Question:

Large multipurpose projects also lead to land degradation.' Explain.

Answer:

Multipurpose projects lead to land degradation because :
(i) Irrigation has changed the cropping pattern of many regions with farmers shifting to water intensive crops. This has led to the salinisation of the soil.
(ii) Regulating and damming of rivers affect the natural flow of rivers causing poor sediment flow.
(iii) The flood plains are deprived of silt.
(iv) Multipurpose projects induce pollution which leads to land degradation.
