Bt Cotton in India: The Only GM Crop Approved Since 2002
How a genetically modified crop revolutionized cotton farming in India
India, being one of the world's largest producers of cotton, witnessed a revolutionary change in cotton farming with the introduction of Bt cotton in 2002. Approved by the Genetic Engineering Appraisal Committee (GEAC) under the Ministry of Environment, Forest and Climate Change, Bt cotton remains the only genetically modified (GM) crop officially approved for commercial cultivation in India till date.
What is Bt Cotton?
Bt cotton is a genetically modified organism (GMO) that contains a gene from the bacterium Bacillus thuringiensis (Bt). This gene produces a protein toxic to certain insect pests, particularly the bollworm, a major threat to cotton crops. The technology helps reduce dependency on chemical pesticides and contributes to improved crop yields.
Approval and Adoption in India
Bt cotton was first approved in India in 2002 after extensive field trials and biosafety assessments. The approval marked a significant milestone for Indian agriculture and biotechnology. Since its commercial release, Bt cotton has been rapidly adopted by farmers, especially in Maharashtra, Gujarat, Andhra Pradesh, and Punjab, due to its pest resistance, reduced pesticide costs, and better yields.
As of today, over 90% of the cotton cultivated in India is Bt cotton.
Impact on Indian Agriculture
1. Increased Yields
Farmers experienced higher cotton yields due to effective control of bollworm pests.
2. Reduced Pesticide Use
Significant drop in chemical pesticides, benefiting environment and farmers' health.
3. Improved Profit Margins
Lower input costs and better harvests improved farmers' income and reduced crop losses.
4. Controversies and Concerns
Despite success, Bt cotton faced criticism regarding secondary pest outbreaks and environmental concerns.
Why No Other GM Crops Are Approved?
While Bt brinjal and GM mustard have undergone trials, their commercial release has been stalled due to public opposition, regulatory hurdles, and debates on biosafety and food security. Bt cotton, being a non-food crop, faced fewer barriers and became the pioneer GM crop in India.
The Road Ahead
With the growing need for climate-resilient and pest-resistant crops, there is a strong case for revisiting India's GM crop policies. More transparent regulations, awareness among farmers, and continuous scientific evaluation can open the doors for more GM crops in the future, benefitting Indian agriculture.
Conclusion
Bt cotton stands as a symbol of agricultural innovation in India, being the only GM crop approved for commercial cultivation since 2002. Its adoption has transformed cotton farming by improving productivity and reducing pesticide use. As India moves towards modernizing agriculture, the debate around genetically modified crops continues. However, the Bt cotton story provides valuable lessons for science-based agricultural policies.
