Today, Indian agriculture finds itself at a crossroads. To make agriculture successful and profitable, proper thrust should be given to the improvement of the condition of marginal and small farmers. The green revolution promised much. But today it’s under controversy. The keyword today is “gene revolution”, which includes genetic engineering. Organic farming is [also] much in vogue today because it is practised without factory-made chemicals such as fertilisers and pesticides. A few economists think that Indian farmers have a bleak future if they continue growing food grains on the holdings that grow smaller and smaller as the population rises. India’s rural population is about 600 million which depends upon 250 million (approximate) hectares of agricultural land, an average of less than half a hectare per person. Indian farmers should diversify their cropping pattern from cereals to high-value crops. This will increase incomes and reduce environmental degradation simultaneously. Because fruits, medicinal herbs, flowers, vegetables, and bio-diesel crops like jatropha and jojoba need much less irrigation than rice or sugarcane. India’s diverse climate can be harnessed to grow a wide range of high-value crops.

Give two reasons why the Green Revolution is under controversy.



Green Revolution is under controversy because:

  1. The excessive use of chemical fertilizers and pesticides decreases soil fertility.
  2. The overutilization of irrigation systems adversely affected underground water.
  3. Agricultural practices like tillage, drainage, intercropping, rotation, and the heavy use of pesticides and fertilizers make flora and fauna vulnerable. Thus, it negatively affected biodiversity.
