2. Ill effect of irrigation occur only when the
scheme is not properly designed and and
implemented. Most of the ill effects are the
result of excess irrigation and unscientific use
of irrigation water. If the water is used
judiciously and scientifically, there would be
practically no ill effects. Some of the common
ill effects are:

3.  WATERLOGGING:
 The excess water due to over irrigation percolates in the
ground and raises the water table.
 Water logging occurs when the water table reaches near
the root zone of crops.
 The soil pores becomes fully saturated and the normal
circulation of air in the root zones of the crops is stopped
and the growth of the crops is decreased. Thus the crop
yield is reduced.
 When water table reaches the ground surface, the land
becomes saline. The land ultimately becomes unfit for
cultivation.

4.  DAMP CLIMATE:
 Because of intense irrigation the climate of the
region becomes quite damp and cold. Such a climate is
not good because the body resistance to deseases is
considerable decreased. Outbreak of various diseases
may occur.

5. MOISQUITOES NUISANCE:
 Due to excessive application of water and due to
leakage from canals, the pits and depressions get
filled up with water. These stragant pools of water
acts as breeding places for mosquitoes and the
region becomes malaria prone.
