Water logging and soil salinity are some of the problems that have come in the wake of the Green Revolution. Discuss their causes and adverse effects to the environment. 

Explanation

Water logging and soil salinity are some of the problems that have come in the wake of the Green Revolution
Irrigation without proper drainage of water leads to water logging in the soil.
Besides affecting the crops, water logging draws salt to the surface of the soil.
The salt then is deposited as a thin crust on the land surface or starts collecting at the roots of the plants.
This increased salt content is inimical to the growth of crops and is extremely damaging to agriculture.
