Answer
Three shortcomings of the Green Revolution are as follows:
- Small farmers could not afford the expensive inputs. Use of machines led to severe unemployment.
- Overuse of chemicals damaged the quality of the soil. Ground water reserves got depleted due to overuse for irrigational purposes.
- There was increase in production of only specific food grains such as wheat and rice. Production of other crops remained unaffected.

Topography refers to the relief features. Levelled landscape always helps in ploughing, irrigating and harvesting crops. Thus, the major farming areas are in the plains. On the other hand, crops such as tea and coffee grow better on hill slopes as they cannot withstand stagnant water. Crops such as rice and jute that require more water are ideally grown in the lowlands. Sometimes broad steps have to be cut on highlands such as mountain slopes, to get the flat terrain required for cultivation of these crops. This is known as terrace cultivation.
