Sougata Bardhan, Associate Professor in the Department of Environmental Sciences at Tennessee State University (TSU), USA, has highlighted that the prevalence of autoimmune diseases has increased compared to previous years. He argues that this rise should prompt scientific investigation into the long-term effects of pesticides and Genetically Modified Organisms (GMOs) to determine if there is a causal relationship. Dr. Bardhan is collaborating with Dr. Anirban Chakraborty of Nitte University Centre for Science Education and Research, Mangalore, to study the long-term impact of these substances on zebrafish, which share over 70% genetic similarity with humans. He cited a study published in Science of the Total Environment (September 2025) that found the herbicide glyphosate caused multi-generational physiological disruptions in mice. Dr. Bardhan also cautioned against a complete switch to organic farming, citing food security risks as seen in Sri Lanka in 1991, and advocated for a balanced approach using modern technology such as slow-release fertilizers, precision nutrient application, AI, and machine learning. He was in India seeking partnerships for the '1890 Centre of Excellence for Land, Water and Resource Management (COE-LWRM)' at TSU.
The relationship between agricultural chemicals and human health has been a subject of concern for decades. [General Knowledge] DDT, a widely used pesticide in the mid-20th century, was banned in many countries after Rachel Carson's 'Silent Spring' (1962) highlighted its ecological and health risks, leading to the establishment of the US Environmental Protection Agency (EPA) in 1970. Glyphosate, a herbicide introduced by Monsanto in 1974 under the brand name Roundup, became the most widely used herbicide globally, particularly with the advent of glyphosate-resistant GMO crops in the late 1990s. [General Knowledge] The International Agency for Research on Cancer (IARC), a part of the WHO, classified glyphosate as 'probably carcinogenic to humans' (Group 2A) in 2015, a conclusion that sparked significant debate and litigation. In India, the use of glyphosate is regulated under the Insecticides Act, 1968. [General Knowledge] The 'One Health' concept, which Dr. Bardhan's research aligns with, gained prominence in the early 2000s, particularly after outbreaks of zoonotic diseases like SARS and Avian Influenza. The concept formally entered global health policy through collaborations among WHO, OIE (now WOAH), and FAO. The high prevalence of autoimmune diseases has been documented in various epidemiological studies globally, with theories linking it to environmental triggers, the 'hygiene hypothesis', and dietary changes. [General Knowledge] The debate in India has often centered around the conflict between promoting agricultural productivity through chemical inputs and the long-term environmental and health costs, as seen in reports like the 'State of India's Environment' by the Centre for Science and Environment (CSE).

15 MayPolitical & Constitutional Dimensions: The debate over pesticides and GMOs touches upon the constitutional right to health (Article 21) and the directive principles on agriculture and environment (Articles 47, 48A). The government, through bodies like the Genetic Engineering Appraisal Committee (GEAC) and the Central Insecticides Board, permits the use of certain chemicals and GM crops after safety assessments. The proponent view, represented by Dr. Bardhan's scientific caution, is that current regulatory approval processes may be based on short-term studies, failing to capture long-term, multi-generational health impacts, thus requiring a policy review informed by the 'One Health' approach. Critics argue that a precautionary approach, while scientifically valid, can stymie agricultural innovation and productivity. There is also a political dimension concerning the influence of powerful agrochemical and seed corporations on policy and the debate around the right to know and label (GM labeling), which involves consumer rights under the Consumer Protection Act, 2019. The article itself does not detail specific political positions, but the tension between promoting agriculture via technology and protecting public health is a core governance issue.
Economic & Financial Impact: The agricultural sector in India is heavily dependent on chemical inputs. A sudden shift away from pesticides and fertilizers, as advocated by some, could have significant economic consequences. Dr. Bardhan warns that a complete switch to organic farming risks food security, citing Sri Lanka's 1991 crisis (where an attempt to ban chemical fertilizers led to a drastic drop in production). This highlights the substantial economic risk of policy overreach. The proponent view for study and potential regulation suggests that the long-term financial burden of health crises linked to pesticides could outweigh the short-term economic benefits of their use. A study into causality could lead to compensation claims, insurance adjustments, and changes in farming costs. Precision agriculture using AI and slow-release fertilizers, as suggested by Dr. Bardhan, requires initial capital investment but can lead to long-term savings through efficient resource use. The financial implications for the insurance sector (crop and health) and the agrochemical industry would be profound if causality is established.
Social Dimensions: The impact is multi-layered. Small and marginal farmers, who depend on pesticides for high yields, could face economic hardship if inputs are restricted without alternatives. The social equity dimension is critical: wealthy consumers can afford organic food, while poorer populations predominantly consume food grown with chemical inputs, potentially bearing a higher health burden. Dr. Bardhan's explanation linking the gut microbiome to agrochemicals and the suggestion to 'consume local produce' also has a social equity dimension—local, seasonal diets are often healthier and more sustainable but may be inaccessible to all. The high prevalence of autoimmune diseases affects the young and working-age populations, imposing a societal cost in terms of lost productivity and increased healthcare expenditure. The proponent view for more research benefits society by potentially preventing a hidden health crisis, while the critic view warns of creating alarm that could disproportionately impact the agricultural community's livelihood.
Governance & Administrative Aspects: Implementation of 'One Health' requires inter-departmental coordination between the Ministries of Health, Environment, Agriculture, and Animal Husbandry, which is often a challenge in India's siloed administrative structure. Dr. Bardhan's criticism of existing safety studies as short-term points to a potential regulatory gap in the approval process for pesticides and GMOs by bodies like the GEAC. Governance challenges include establishing a robust, independent, and long-term surveillance system to monitor environmental and health effects. The use of AI and machine learning in precision agriculture, while promising, requires significant capacity building among extension services and farmers. A central challenge is balancing federalism—where agriculture is a state subject—with the need for a national policy framework on pesticides and GMOs. The article does not discuss specific administrative hurdles, but the call for long-term studies implies a need for institutional capacity and stable multi-year funding for research, which is often difficult to sustain.
