GM Crops Debate

Genetically Modified (GM) crops are plants whose DNA has been altered using genetic engineering techniques to incorporate desirable traits such as pest resistance, herbicide tolerance, or enhanced nutritional content. In the Indian economy, GM crops represent a significant technological intervention under the “Agricultural Inputs and Technology” unit, sparking a multi-dimensional debate involving food security, environmental biosafety, and corporate ethics.

Regulatory Framework in India

The regulation of GM crops is a stringent process governed by the Environment Protection Act (EPA), 1986.

• Genetic Engineering Appraisal Committee (GEAC): Functioning under the Ministry of Environment, Forest and Climate Change (MoEFCC), it is the apex body responsible for the appraisal of activities involving large-scale use of hazardous microorganisms and recombinants. It grants environmental clearance for field trials and commercial release.
• Review Committee on Genetic Manipulation (RCGM): Functioning under the Department of Biotechnology (DBT), it monitors safety-related aspects of ongoing research projects and issues permits for restricted field trials.
• State Biotechnology Coordination Committee (SBCC): Provides a monitoring mechanism at the state level.

Current Status of GM Crops in India

India’s experience with GM crops is characterized by the massive success of a non-food crop and ongoing deliberation over food crops.

• Bt Cotton: The only GM crop approved for commercial cultivation in India (since 2002). It uses genes from the soil bacterium Bacillus thuringiensis to produce a protein toxic to the Bollworm.
• GM Mustard (DMH-11): Developed by the Centre for Genetic Manipulation of Crop Plants (CGMCP), Delhi University. It uses the ‘barnase-barstar’ system for hybrid seed production. It received environmental clearance from GEAC in 2022 but remains subject to judicial review.
• Bt Brinjal: Developed by Mahyco in collaboration with public universities. Despite GEAC approval in 2009, the government imposed an indefinite moratorium in 2010 due to public and environmental concerns.

The Pro-GM Arguments: Economic and Productivity Gains

Proponents, including biotechnologists and seed industry bodies, highlight the efficiency of GM technology in addressing resource scarcity.

• Yield Stability: Resistance to pests (like the Pink Bollworm) and diseases ensures that the “yield gap” is minimized, directly impacting food security.
• Reduced Input Costs: By reducing the dependency on chemical pesticides, GM crops can lower the overall cost of cultivation for farmers.
• Climate Resilience: Biotechnology allows for the development of “Climate Smart” varieties that can survive abiotic stresses like salinity, drought, and submergence.
• Nutritional Enhancement: Bio-fortification (e.g., Golden Rice with Vitamin A) can address “hidden hunger” or micronutrient deficiencies in the Indian population.

The Anti-GM Arguments: Environmental and Socio-Economic Risks

Critics, including environmentalists and organic farming advocates, raise concerns regarding long-term sustainability and biosafety.

• Environmental Biosafety: Concerns about “Gene Flow” or cross-pollination where GM genes might transfer to wild relatives or non-GM varieties, potentially creating “super-weeds.”
• Impact on Biodiversity: Potential harm to non-target organisms, such as honeybees and butterflies, which are essential for natural pollination.
• Monopoly and Seed Sovereignty: The high cost of GM seeds and the dominance of multinational corporations (MNCs) through Intellectual Property Rights (IPR) may lead to farmer debt and dependency.
• Health Concerns: Allegations of potential allergenicity or antibiotic resistance in humans, though scientific consensus generally deems currently approved GM foods safe.

Comparison of Major GM Initiatives in India

Recent Policy Shifts and Technological Evolution

• Exemption of SDN-1 and SDN-2: In 2022, the Ministry of Environment exempted Site-Directed Nucleases (SDN) 1 and 2—categories of genome-edited crops—from the stringent biosafety regulations applicable to GMOs, provided they do not contain foreign DNA.
• Kisan Drones and Precision Farming: The integration of GM crops with digital tools like drones for localized spraying is being explored to further optimize input use.
• HTBt Cotton: Herbicide Tolerant Bt Cotton is a new generation of cotton that allows farmers to spray glyphosate to kill weeds without harming the crop. While widely grown illegally in India, it has not yet received formal commercial approval.

Fact-File for UPSC Prelims

• Cartagena Protocol on Biosafety: An international treaty governing the movements of Living Modified Organisms (LMOs) resulting from modern biotechnology. India is a signatory.
• Pink Bollworm Resistance: One of the primary reasons for the debate on the efficacy of first-generation Bt Cotton (Bollgard I) in India today.
• Indigenous Innovation: DMH-11 (GM Mustard) is significant because it is a “public-sector” GM crop, countering the narrative of MNC dominance in the sector.
• Food Safety and Standards Authority of India (FSSAI): Responsible for regulating the manufacture, storage, distribution, sale, and import of GM foods once they enter the food chain.
• Terminator Technology: A genetic modification that prevents a crop from producing viable seeds for the next season; it is legally prohibited in India to protect farmers’ rights.
