Trek through the upper regions of the Himalayas and you will realize that there is one thing noticeably missing. The herbs found at particular elevations and known by names were thinning, and in some cases, disappeared altogether.
However, this did not happen quickly. The effects of changes in climate brought about earlier growing seasons. At the same time, the demand of the herbal medicines business exceeded supply. In the process, there was also a loss of other aspects, which India was yet to recognize: from herbs to the pharmacology associated with them, to the lives dependent on them, to the ecology that supported them.
When the warning was made clear, most of these species were already threatened.
An Unusual Answer
Dr. Richard Lobo, who heads R&D and innovation at Tata Chemicals, kept returning to a question that sounds simple but isn’t: how do you grow something that’s disappearing, at scale, without making the problem worse?
Aeroponics — suspending plant roots in air and feeding them through a calibrated mist — had been around in commercial agriculture for years. What Tata Chemicals did was apply it to a category of plants most agri-tech operations wouldn’t touch: high-value, ecologically sensitive medicinal species that don’t behave like tomatoes or lettuce.
The results have been striking. The programme has recorded up to 6X yield improvements over conventional cultivation of these plants. Water consumption has dropped by 80 percent. Nutrient delivery, because it bypasses soil entirely, is far more precise — which matters enormously when consistency of chemical composition is what gives a medicinal herb its value.
No soil. No runoff. No dependence on monsoons that no longer arrive on schedule.
Nanded: The Classroom That Grows Things
A facility in Nanded, Maharashtra is where the theory meets actual farmers.
Tata Chemicals has opened its aeroponics centre not just as a cultivation unit but as a working demonstration space for farmers and Farmer Producer Organisations. FPOs from the region walk through, watch the misting cycles, understand the economics, and leave with something more durable than a brochure.
The broader significance of Nanded is what it represents for communities navigating climate unpredictability. Year-round productivity inside a controlled environment breaks the dependence on season and rainfall that has made traditional cultivation of these plants so precarious. A farmer cultivating an indigenous medicinal plant in the Himalayas from Maharashtra now doesn’t have to go to the Himalayas, provided he has got the right environment, facilitated by Tata Chemicals. This would definitely be an important development. No revolution, but surely a structural change.
The Real Bet: Conservation, Not Just Cultivation
The commercial logic of aeroponics is evident enough. What’s more surprising is what Dr. Lobo’s team is attempting on the conservation side.
Several of the Himalayan species being cultivated are rare — not rare in the market-value sense, but genuinely at risk of disappearing from their native habitats within this generation. The programme is working to establish viable populations of these plants in controlled environments precisely because the mountains can no longer be relied upon to sustain them.
This is ex-situ conservation dressed in agricultural clothing. The goal isn’t a seed bank or a museum specimen. It’s a living, productive population of plants that can survive, be studied, and remain accessible — while the knowledge tied to them stays in practice rather than in archives. The ambition, stated plainly, is that future generations should encounter these herbs not in a historical record but in the world.
What Tata Chemicals Is Actually Saying
The company frames all of this under its organisational principle — “Serving Society through Science” — which in most corporate contexts functions as decoration. Here it’s doing actual work.
Connecting an R&D programme to both farmer resilience and species conservation simultaneously is not the obvious path for a chemicals company. It requires institutional patience that commercial timelines don’t usually reward. Whether the Nanded model eventually scales into the Himalayan valleys it’s designed to serve depends on adoption rates, policy support, and the pace of ecological deterioration it’s racing against.
But the scientific groundwork is credible, the data from the cultivation programme is real, and the farmers walking through that facility in Nanded are already changing how they think about what’s possible. In mist-fed roots and one quietly determined R&D team, something worth watching is taking shape.
