2-Minute Revision

GM Crops are plants engineered with altered DNA to introduce desirable traits like pest resistance (e.g., Bt cotton), herbicide tolerance, or enhanced nutrition (e.g., Golden Rice). In India, the regulatory landscape is governed by the Environment (Protection) Act, 1986, with the Genetic Engineering Appraisal Committee (GEAC) as the apex body.

GEAC conducts rigorous biosafety assessments, including multi-stage field trials, adhering to the 'Precautionary Principle' due to potential risks. Currently, Bt cotton is the only GM crop commercially approved in India, demonstrating initial success in pest control and yield but also raising concerns about secondary pests, resistance development, and high seed costs.

GM food crops like Bt Brinjal and Golden Rice face an indefinite moratorium or delayed approvals due to public apprehension, ethical debates, and socio-economic concerns, particularly regarding farmer dependence and Intellectual Property Rights (IPR) issues.

The 'Gene Revolution' (biotechnology) is often contrasted with the 'Green Revolution' (conventional breeding, inputs), each with distinct impacts on productivity, environment, and farmer livelihoods. Understanding India's cautious yet evolving policy, balancing food security with biosafety and farmer welfare, is crucial for UPSC.

5-Minute Revision

Genetically Modified (GM) crops represent a significant advancement in agricultural biotechnology, involving the precise alteration of a plant's genetic material to introduce or enhance specific traits.

These traits typically include insect resistance (e.g., Bt cotton, producing Cry proteins against bollworms), herbicide tolerance (e.g., Roundup Ready crops), disease resistance, and nutritional enhancement (e.

g., Golden Rice for Vitamin A). The scientific process involves gene isolation, insertion into a vector, and regeneration of modified plant cells. In India, the regulatory framework is robust but complex.

The Environment (Protection) Act, 1986, and its 1989 Rules form the legal backbone, establishing the Genetic Engineering Appraisal Committee (GEAC) under the MoEFCC as the primary regulatory authority.

GEAC is responsible for evaluating biosafety, approving field trials, and recommending commercial release, guided by the 'Precautionary Principle.' Constitutional articles like 48A (environmental protection) and 21 (right to life/food) also underpin the regulatory approach.

While Bt cotton is the only GM crop commercially approved in India, demonstrating initial success in boosting cotton production, it has also faced challenges like pest resistance and IPR concerns. GM food crops, such as Bt Brinjal and DMH-11 mustard, have encountered significant public and political resistance, leading to moratoriums or prolonged approval processes.

The debate around GM crops encompasses potential benefits like increased yields, reduced pesticide use, and climate resilience, against risks such as gene flow, impact on biodiversity, potential health effects, and socio-economic issues like seed monopolies and farmer dependence.

The 'Gene Revolution' is distinct from the 'Green Revolution' in its technological approach and specific objectives. For UPSC, a comprehensive understanding requires analyzing these scientific, regulatory, economic, environmental, and ethical dimensions, focusing on India's unique policy challenges in balancing innovation with caution and ensuring sustainable, equitable agricultural development.
