Quick takeaways
Dr. MS Swaminathan played a vital role in India's agricultural revolution by collaborating with Dr. Norman Borlaug and introducing high-yielding dwarf wheat varieties, resulting in a significant increase in wheat production from 10-12 million tonnes to over 110 million tonnes.
The green revolution led to short-term gains in agricultural productivity, but the excessive use of fertilizers has caused soil degradation, soil toxicity, and concerns about long-term food security, emphasizing the need for a sustainable approach that combines science with ecology.
Deep dives
India's Green Revolution
In the 1960s, India witnessed a significant increase in wheat production through the adoption of crossbreeding techniques. Dr. MS Swaminathan played a vital role in this agricultural revolution, collaborating with American scientist Dr. Norman Borlaug and importing the Mexican dwarf variety of wheat. These genetically modified crops showed higher yields and disease resistance. As a result, India's wheat production skyrocketed from 10-12 million tonnes in the early 1960s to over 110 million tonnes today. Similar efforts were made to address the rice shortage problem. Dr. Swaminathan's contributions earned him the title 'father of the green revolution'. However, the indiscriminate use of fertilizers has led to concerns about desertification, soil degradation, and food security, calling for an 'evergreen revolution' that combines science with ecology.
Challenges of the Green Revolution
While the green revolution brought significant gains in agricultural productivity, it also presented challenges. Dr. Swaminathan warned about the consequences of neglecting soil fertility, excessive use of pesticides, and unsustainable groundwater extraction from the inception of the green revolution. Today, the use of heavy nitrogen, phosphorus, and potassium-based fertilizers is causing an imbalance in soil composition, with nitrogen levels reaching alarming levels. The short-term gains in output may be compromised in the long run as the soil becomes toxic. A 2019 report highlighted the urgent need for a sustainable approach that combines science with ecology to ensure long-term food security.
Last week, one of the architects of India’s agricultural revolution passed away at the age of 98. So in today’s episode for 3rd October 2023, we decided to look back on India’s tryst with high-yielding crop varieties.
