The green Revolution solved the problem of shortage of food grains to quite an extent but it also led to major utilization of water, electricity and chemical fertilizers. This has resulted in the shortage of water and electricity for farming and also affected the quality of soil since the naturally occurring organic matter has been depleted beyond means while causing an alarming increase in the chemicals in the environment.
Increase of chemicals in the environment including air, soil and water and resulted in increase of number of health hazardous diseases. These diseases affect human, animal and plant life.
Some common problems that are have arisen from the intensity of the Green revolution are soil degradation, air and water pollution, decline in soil fertility, depletion of ground water, flooding, increase in salination of water and stunted irrigation efficacy. For all these reasons, farmers are being asked to turn to organic farming on a large scale. Organic farming can help:
- Cut down on the use and cost of chemical fertilizers and pesticides.
- Increase the biodiversity of insects and microorganisms that perform natural pest control thus decreasing the dependence on natural pesticides.
- Reduce dependence on ground water and farm power for irrigation. Many organically grown crops do not need regular watering and can sustain themselves on the rain water itself.
- Utilize crop residue for preparing organic fertilizers. This way one need not get into the hassle of buying expensive chemical fertilizers while giving providing complete organic care to the crops.
