Green revolution refers to the drastic increase in food production during 1960s in the developing countries.
Two intended outcomes: 1. HYV seeds enhance the productivity level. 2. Use of modern machinaries promote huge yield per unit of land.
Two unintended outcomes: 1. Loss of soil fertility. 2. Increase of salinity in under ground water.
Explanation:
In 1960s green revolution brought a drastic change in India's agricultural pattern. Yield per unit of land increase rapidly. It introduced the use of modern machineries, pesticide & weedicides in the crop land, HYV (High yielding variety) seeds etc.
