‘Rethinking language biases would enable us to look more holistically at agroecological practices’

Molecular biologist Sujata Goel on the importance of "weeds", modern approaches in science communication & India’s organic farming policies
Published on

Nearly 30 years ago, molecular biologists Sujata Goel and her partner Anurag left Delhi to build a life closer to nature in Karnataka’s Kodagu district. Over the years, they began working closely with local farmers to understand how agroecological plantations could be developed at scale, combining their expertise in academic biology with generations of local ecological knowledge to co-create natural solutions for coffee and spice plantations. Communication techniques that closed language and knowledge gaps were essential in this confluence of modern scientific understanding with centuries-old local wisdom.

The couple has been actively researching natural alternatives to chemical pesticides, starting with a makeshift laboratory on a wooden table on their 25-acre ecologically sustaining plantation to test how certain plant species that are considered “weeds” have properties to turn away pests and provide other benefits to cultivated plants. Since then, Sujata has taken their research to public platforms and official channels to advocate for bans on use of agri chemicals in Coorg’s coffee and spice plantations. Coorg is home to Talakaveri, the source of River Kaveri — the lifeline of multiple South Indian states. The chemicals sold to and used by planters, seep into the soil and contaminate this vital waterbody.

Today, Sujata works with a small team of farmers, naturalists and conservationists to bring awareness about the lethal impacts of weedicides that has gradually crept into the agricultural practices in and around plantations in this area. 

She has also taken these ideas to the international stage through the Organic Farming Association of India, serving as its president and helping organise a global symposium in 2017. In the conversation with Down To Earth, she discusses the methods and importance of such dialogue, the evolving approaches of communicating science with local communities and what she has learnt about organic farming in India as a practitioner. 

Preetha Banerjee: How has science communication changed over the years and what channels and techniques do you use to raise awareness among local farmers? What has been the impact of the Internet?

Sujata Goel: Most people across villages including farmers use the internet comprehensively. Several village Panchayats, Planters and Farmers have created Whatsapp groups to exchange and share information regarding everything related to cultivation, from weather forecasts to agricultural practices, government schemes and subsidies available, and other related matters. We are using such platforms in collaborations with scientists to spread awareness about the carcinogenic and lethal effects of many of the agrichemicals which are rampantly being used in the fields now. It is important to remember that these lands constitute a catchment area being the primary recipients of the South-west monsoons, providing water for much of peninsular India. Spraying pesticides and weedicides around paddy fields have contaminated wetlands, which is extremely dangerous since these wetlands are the life source of all flowing water. These wetlands are also precious because they recharge ground water and must be protected from such thoughtless destruction at all costs.  

PB: Over three decades of working with farmers, how have you seen science communication evolve?

SG: Whatsapp groups and Instagram seem to be the most accessible to farmers. Since multiple language use is now possible, these are popular, especially in rural areas. Several workshops are also held remotely, and farmers are able to attend them from their own places of residence and work. This helps cut costs of holding such study programs and enables organisations such as Organic Farming Association of India (OFAI) to invite scientists to such platforms without disrupting their work schedules.

PB: Modern agricultural science promotes a negative association with “weeds”. Is there another way to look at weeds? What have you learnt from traditional wisdom and your own research?

SG: Words like “pest” and “weed” have evolved through western agricultural practices. They tend to designate some species desirable and others not. Many native plants which we call weeds were consumed as food not long ago and continue to do so. Many species which we eliminate under the garb of “weeds” play an essential role not only in the overall ecosystem, but also in producing our own food. They not only create habitats for local biodiversity but also offer pollinators necessary grounds for foraging and survival. Rethinking our language biases would enable us to look more holistically at the philosophy behind our practices.

This brings us to the issue of weedicides, which have slowly infiltrated Kodagu’s coffee plantations in the past ten years. We now notice deformities and dead bodies of animals in the once-lively streams that are the arteries of this landscape. The poisoning of freshwater species is just an indicator of the impact these chemicals have on human health. 

This year, in February 2026, the multinational company, Bayers, announced that it will pay $7.25 billion to settle thousands of US lawsuits alleging that its Roundup weedkiller has caused a vast number of individual cases of cancer. That these family of carcinogenic agri-chemicals were lethal to all life forms was substantiated by rigorous scientific research decades ago and has been available in the public domain, and yet their marketing continues unabated. Are these the substances which international companies promote and enforce on the planet and escape all forms of control? Who becomes accountable for such acts of deliberate genocide?

PB: Why is it important to think about biodiversity as an entire ecosystem rather than as individual species? What does this mean for agricultural productivity?

SG: Sustenance of the ecology of a farm depends upon the richness of its biological diversity. Plants and insects, fungi and soil microorganisms have all co-evolved for millions of years. Good farming practices aim to understand the importance of biodiversity and try to mimic nature by providing niches for diverse plants, animals, insects, bacteria and fungi. The ‘ecosystem services’ provided by this biodiversity are invaluable, not just for farmers, but for all of life surrounding us. These range from encouraging populations of pollinators, soil recharge and nutrient cycling, disease regulation, water harnessing, and carbon sequestration among others.

On organic farms such as ours that have no trace of chemicals around, parasitic and predatory insects colonise native plant species and play significant roles in maintaining disease-free crops. Integration of fallow areas, leaving riparian stretches rich with local weeds, and generous mulching has allowed a rich buildup of biodiversity in the fields. As a result, we now have excellent populations of spiders, wasps, dragonflies, frogs, lizards, snakes and a wide range of birds, all of which contribute towards building up of a diverse and healthy agri-ecosystem.

Birds are amazing for their ability feed on insects and caterpillars; spiders are indiscriminate trappers of a whole range of insects. Wasps lay their eggs on larvae, which hatch and being carnivorous, start feeding on the grubs which would otherwise be a part of the pest population of the crops. Bats, frogs, skinks, lizards, shrews, mantids, are insect feeders and form an intricate link in the food web of the forest ecosystem.

Beneficial microorganisms contribute to a rise in detritus activity of the soil, increased nitrogen fixation, and increase in nutrient cycles. Areas where grasslands are encouraged become sponges for harnessing rainwater to replenish water tables and aquifers. It is these who are the true regenerators of our soils and agri-ecosystems.

PB: How has India's approach to organic farming changed over the past three decades?

SG: Across our agricultural landscapes, farmers are beginning to feel the “bite” of 60 years of aftermath of the green revolution. Widespread losses due to climate extremes being experienced in different parts of the world now are adding to the need to desperately regenerate degraded lands. This is possible only through farming practices which totally exclude use of agri-chemicals, and at the same time, enabling viable practices to revive our soils.

There is no half measure. The governing bodies of our country must make up their minds that when they announce policies and projects to support organic farming, whether that is their true intent and how such projects can be implemented in light of subsidies and other supportive mechanisms offered for purchases of the very agri-chemicals which are responsible for the damage. Through field-based education and changes in policies to ensure that farmers are economically protected, it is possible to scale up on organic practices to feed our populations. This has been amply demonstrated by the truly progressive farmers across the world.
