Q.In view of the current food crisis, it is said, that we need another green revolution. Highlight the major limitations of the earlier green revolution.

The earlier Green Revolution, while significantly increasing food production, faced several critical limitations that highlighted the need for alternative approaches.

• Despite tripling the food supply, it proved insufficient to meet the demands of a continuously growing human population.
• Its success was heavily dependent on the extensive use of agrochemicals, including chemical fertilizers and pesticides.
• The high cost of these essential inputs placed a substantial economic burden on farmers, particularly in developing countries. …

The Green Revolution, initiated in India during the mid-1960s, was a pivotal moment in the nation's agricultural history. It was primarily driven by the introduction of High-Yielding Varieties (HYVs) of wheat and rice, coupled with increased use of chemical fertilizers, pesticides, and improved irrigation facilities. This revolution successfully transformed India from a food-deficient nation reliant on imports to one that achieved self-sufficiency in food grain production, averting widespread famine. However, in the face of current food security challenges and the call for a "second Green Revolution," it becomes crucial to critically examine the limitations of the earlier one to inform future strategies.

While undeniably successful in its primary goal of increasing food output, the first Green Revolution was not without significant drawbacks, which have become more apparent over time. These limitations underscore the need for a more holistic and sustainable approach to agricultural development.

• Environmental Degradation: The intensive farming practices promoted by the Green Revolution placed immense pressure on natural resources.

  • Soil Health: The indiscriminate and excessive use of chemical fertilizers led to a decline in soil fertility over the long term, altering its natural composition and reducing its organic matter content.
  • Water Pollution: Runoff from fields laden with chemical fertilizers and pesticides contaminated groundwater and surface water bodies, posing risks to human health and aquatic ecosystems.
  • Groundwater Depletion: The reliance on extensive irrigation, particularly through tube wells, led to the over-extraction of groundwater in many regions, causing water tables to fall drastically.
  • Loss of Biodiversity: The focus on a few HYVs of staple crops often led to the displacement of traditional, diverse crop varieties and local ecosystems, reducing agricultural biodiversity and making the system more vulnerable to pests and diseases.

• Regional Disparities: The benefits of the Green Revolution were not evenly distributed across the country.

  • The revolution largely concentrated its impact on regions with assured irrigation facilities and favorable agro-climatic conditions, primarily Punjab, Haryana, and Western Uttar Pradesh.
  • Other regions, particularly the rain-fed areas and those lacking adequate infrastructure, saw minimal gains, leading to an exacerbation of regional economic imbalances.
  • The focus was predominantly on wheat and rice, neglecting other important crops like pulses, oilseeds, and coarse grains, which are crucial for nutritional security and often grown in less developed regions.

• Socio-economic Disparities: The Green Revolution also widened the gap between different sections of the farming community.

  • Benefit to Larger Farmers: Farmers with larger landholdings and access to capital could more easily adopt the new technologies, invest in HYV seeds, fertilizers, pesticides, and irrigation infrastructure. This allowed them to reap greater profits. …

Method — ask "what did the first Green Revolution NOT fix?"

List what it relied on (HYVs + fertiliser + irrigation + pesticides) and what that created:

• Population growth outpaced even the tripled output.
• Heavy agrochemical dependence raised costs and environmental damage. …
