How has the green revolution influenced our present agricultural system

The green revolution led to high productivity of crops through adapted measures, such as (1) increased area under farming, (2) double-cropping, which includes planting two crops rather than one, annually, (3) adoption of HYV of seeds, (4) highly increased use of inorganic fertilizers and pesticides, (5) improved irrigation facilities, and (6) improved farm implements and crop protection measures (Singh, 2000; Brainerd and Menon, 2014) and modifications in farm equipment.

This model did increase food production globally but the came with envrionmental and socio-economic trade-offs. One of the trade-offs includes food security – which is socio-economic in nature. The ‘Green Revolution’ tended to favor the farmers that were already better off.


The Trade-offs – Ecosystems Functions

Here too the ‘Green Revolution’ had a trade-off in terms of ecosystem function or environmental impact because of the heavy use and reliance on water supplies. For example, irrigation through surface water and groundwater has led to the overuse of waters and the depletion of water and the over-drafting of the water tables.

The Study


The Results

  • The Green Revolution laid the foundation for a subsequent era of genetically modified crops, globalization of agriculture, and even greater dominance of agribusiness giants in the food system. Today, consumers are often disconnected from the people who grow their food and how it is grown. And while production has increased, so has the number of und…
