GENETIC MODIFICATION

GENETIC MODIFICATION

Agricultural experiments in India have a long and dubious record, but biotechnology has added a new twist with genetically modified crops. The use of genetic engineering tools to address agricultural vulnerabilities is not just limited to India. A number of other countries are in line to deploy new genetic modified tools as well. India, USA, Brazil, Argentina and Canada are 5 top GM growing countries, together accounting for approx. 90% area of the Genetically Modified cultivation. While proponents of genetic modification argue that it has the potential to solve India's agricultural productivity problem, opponents point to the negative implications on environment and human health. It is therefore essential to conduct a more thorough and comprehensive assessment of Indian agriculture's experiences with genetic modification.

Genetic Modification

• Genetic modification” involves altering the genes of an organism, be it a plant, animal or microorganism.
• GM technology involves direct manipulation of DNA instead of using controlled pollination to alter the desired characteristics.
• It is one the approaches to crop improvement, all of which aim at adding desirable genes and removing undesirable ones to produce better varieties.

Regulations of Genetic Modified Crops in India

• In India, the regulation of all activities related to Genetically modified organisms and products are regulated by the Union Ministry of Environment, Forest and Climate Change( MoEFCC) under the provisions of the Environment (Protection) Act, 1986.
• Genetic Engineering Appraisal Committee (GEAC) under MoEFCC is authorised to review, monitor and approve all activities including import, export, transport, manufacture, use or sale of GMO.
• GM foods are also subjected to regulations by the Food Safety and Standards Authority of India (FSSAI) under the Food Safety and Standards Act, 2006.
• GEAC recently approved commercial cultivation of genetically modified mustard.
• Before that Bt cotton was the only GM crop that was approved for commercial cultivation in 2002.
• ‘Bt’ is shorthand for Bacillus thuringiensis, a bacterium found mainly in the soil that produces proteins toxic to some insects, especially the cotton bollworm.

Contributions of Genetic Modification Technique

• Revolutionised Pharma Sector: GM microbes and plants revolutionised the production of complex pharmaceuticals by enabling the generation of safer and cheaper vaccines and therapeutics. Mass production of GM technology based human insulin, vaccines, growth hormones and other drugs has greatly facilitated the availability and access to life saving pharmaceuticals.
• Herbicide Tolerance: Genetic Modification has played a key role in herbicide tolerance and transformed crops to tolerate specific broad-spectrum herbicides, which kill the surrounding weeds, but leave the cultivated crop intact.
• Climate Change Adaptation: Genetic Modification is already being used to help the plants adapt to the rapidly changing climate. Researchers are developing strains of rice, maize and wheat capable of withstanding longer droughts and wetter monsoon seasons.
• Salinity Tolerance: Scientists have genetically modified plants to tolerate high levels of salt offering a potential solution to growing food in salty soils. The researchers inserted a gene to remove salt present in the form of sodium ions from water before it reaches the leaves and also adjusts the ionic and osmotic balance of cells in roots.
• Contributor to Food Security: Genetic Modification has improved crop yield, resulting in greater production of the target crop. Scientists have also engineered pest-resistant crops, helping local farmers better withstand environmental challenges that might otherwise wipe out a whole season of produce.

Concerns Related to Genetic Modification

• Loss of Indigenous Variety: Genetically modified production imposes high risks to the disruption of ecosystem and biodiversity because the better traits produced from engineering genes can result in the favouring of one organism. Hence, it can eventually disrupt the natural process of gene flow and affect the sustainability of indigenous variety.
• Risk of Allergic Reactions: Genetically modified food has immense potential of allergic reaction because it is biologically altered. The sudden emergence of genetic modification may have a common side effect of allergic reaction for humans who have adapted to the conventional variety.
• Threat to Wildlife: Altering the genes of plants can also have serious effects on wildlife. For example, genetically modified plants, such as tobacco or rice, that are used to produce plastic or pharmaceuticals, can endanger mice or deer who consume crop debris left in the fields after harvesting.

Solutions for Genetic Modification Technique

• Towards Bio-Safety: There is a need to prevent large-scale loss of biological integrity, focusing both on agricultural production as well as plant, animal and human health. Creation and use of genetically modified crops must be done in collaboration with stewards of ecosystems in order to meet the needs of the environment, local populations, and the wider global community.
• Complementing Genetic Modification: Genetic modifications are not the only solution for food security, it must be combined with improved farming credit, better use of water and reducing waste, to create better food options and sustainable crop management.
• Technical Competency for Effective Regulation: All regulatory bodies of gm crops, especially the GEAC, should be made technically competent. Specific competence on Risk Assessment and Risk Management of GM crops including Monitoring and Information Systems skills are the need of hour. Also, there is a need to create with immediate effect legally mandated District Level and Panchayat level Committees for faster documentation, and analysis of GM crops.
• Bottom-Up Genetic Modification: There should be a consultative and participatory process to prioritise crops and traits for genetic improvement through biotechnology with the goal of addressing the needs of small farmers.
• Indigenous Gene Banks: It is important to preserve the indigenous variety due to its ability to adapt to diseases and nutritional value.
