Gm crops in India: the science, controversy, and future of food security

In late 2024, the Ministry of Environment, Forest and Climate Change (MoEFCC) introduced the Draft Manufacture, Use, Import, Export, and Storage of Hazardous Micro-Organisms/Genetically Engineered Organisms or Cells (Amendment) Rules, 2024. This move, aimed at enhancing transparency within the Genetic Engineering Appraisal Committee (GEAC), responds directly to a Supreme Court directive to address conflicts of interest in the regulatory process. This development brings India’s complex relationship with agricultural biotechnology, particularly Genetically Modified (GM) crops, back into the national spotlight, especially with the fate of GM Mustard hanging in the balance.

What are Genetically Modified (GM) Crops?

Genetically Modified Organisms (GMOs) are living beings—plants, animals, or microbes—whose genetic material has been artificially manipulated in a laboratory through genetic engineering. GM crops are plants developed by introducing specific, desirable genes, often from another species, to achieve traits like pest resistance, herbicide tolerance, or enhanced nutritional value.

The technology to create them is rooted in our understanding of DNA, a field massively advanced by initiatives like the Human Genome Project, which mapped the entire human genetic code. Common methods to create GM crops include:

• Gene Gun (Biolistics): Tiny metal particles coated with the desired DNA are shot into plant cells.
• Agrobacterium-mediated transformation: A soil bacterium, Agrobacterium tumefaciens, which naturally transfers DNA to plants, is used as a vehicle to insert the gene of interest.

Fun Fact: The first GM crop approved for sale in the U.S. was the Flavr Savr tomato in 1994, which was engineered for a longer shelf life.

The Status of GM Crops in India

India’s journey with GM crops has been cautious and contentious. The regulatory landscape is stringent, and public and political debate is intense.

Analogy: The Barnase-Barstar system for creating hybrid mustard works like a temporary “key and lock”. The ‘Barnase’ gene (the lock) makes the plant male-sterile so it can’t self-pollinate. The ‘Barstar’ gene (the key) from the other parent plant is then introduced during cross-pollination, which unlocks fertility and allows the hybrid seed to grow.

Regulating GMOs in India

The regulation of all GMOs and products derived from them is governed by the Environment (Protection) Act, 1986 and the Rules, 1989. Several committees are involved in this multi-tiered process.

Mnemonic for Regulatory Bodies: To remember the hierarchy, think: “Good Regulators In States & Districts” (GEAC, RCGM, IBSC, SBCC, DLC).

Critical Policy Appraisal

The debate over GM crops involves a trade-off between potential benefits and significant risks.

Fun Fact: Globally, over 190 million hectares were planted with biotech crops in 2019, with the top five countries being the USA, Brazil, Argentina, Canada, and India.

Analytical Lens: UPSC Focus (Mains & Prelims)

Conceptual Basis: The legal and regulatory framework for GM crops in India is anchored in the Environment (Protection) Act, 1986 and the subsequent “Rules for the Manufacture, Use/Import/Export and Storage of Hazardous Micro Organisms/Genetically Engineered Organisms or Cells, 1989”.

UPSC Integration: Connecting the Dots

• GS-II (Polity & Governance): The GM crop issue highlights the functions of statutory regulatory bodies (GEAC), the tension in federalism (state permissions for trials), and the role of judicial oversight (Supreme Court interventions).
• GS-III (Economy & Agriculture): It is central to topics like food security, doubling farmers’ income, intellectual property rights (seed patents), and the role of technology in agriculture.
• GS-III (Environment & S&T): The topic directly involves biotechnology, biosafety, biodiversity conservation, and the environmental impact of new technologies.

Expert Analysis & Future Outlook: The future of GM food crops in India hinges on building a robust, transparent, and trusted regulatory ecosystem. The Supreme Court’s 2024 directive for a national policy is a pivotal opportunity. The path forward requires balancing the promise of technological solutions for food security and climate resilience with rigorous, science-based biosafety assessments and socio-economic considerations. Public engagement and addressing the concerns of farmers and consumers are non-negotiable for the successful and ethical adoption of this technology. The fate of GM Mustard will be a litmus test for India’s agricultural biotechnology policy for the next decade.

Prelims Practice Question (MCQ): Which of the following is the apex body in India responsible for the approval of the commercial release of Genetically Modified (GM) crops? a) Review Committee on Genetic Manipulation (RCGM) b) Department of Biotechnology (DBT) c) Genetic Engineering Appraisal Committee (GEAC) d) Indian Council of Agricultural Research (ICAR)

Answer: (c) Genetic Engineering Appraisal Committee (GEAC) Explanation: The GEAC, functioning under the Ministry of Environment, Forest and Climate Change (MoEF&CC), is the statutory body responsible for appraising and approving the large-scale use and commercial release of GMOs and products thereof into the environment as per the Rules, 1989 of the Environment (Protection) Act, 1986.

Mains Sample Question (15 Marks): “While Genetically Modified (GM) crops offer a promising technological solution to India’s food security and climate change challenges, their introduction is fraught with complex regulatory, socio-economic, and ethical concerns. Critically analyze this statement in the context of the recent developments related to GM Mustard.”
