Solution
The correct option is C Green revolution
Waterlogging and soil salinity are some of the problems that have come in the wake of the Green Revolution. Waterlogging and soil salinity is caused by extensive irrigation without proper drainage of water. The continuous presence of water draws salt to the surface of the soil, which gets deposited as a thin crust on the land surface or starts collecting at the roots of the plants. Adverse effects (i) Increased salt content stunts the growth of (ii) crop plants, (iii) Root cells saturated with saline water gets damaged. (iv) Plants die. (v) Crop yield gets affected. (vi) The financial loss to the farmers. Although properly managing the soil-water system can correct the salination and waterlog, but the economic costs of this are very high.
So, the correct answer is 'Green revolution'.
