In 2023, India declared the International Year of Millets and made millet promotion a centrepiece of its G20 presidency. This was not merely a diplomatic gesture. Behind it was a convergence of crises: groundwater depletion from water-intensive rice and wheat cultivation, a diabetes epidemic directly linked to the shift away from low-GI millets, and the economic collapse of millions of farmers whose input costs for chemical farming exceeded their market returns. Millets — which require no irrigation, no synthetic fertiliser, and no pesticide — are being reconsidered as a solution to all three.
The Green Revolution's hidden costs
The Green Revolution (1960s–1980s) increased Indian wheat and rice yields dramatically — averting famine and feeding hundreds of millions. Its costs were less visible: it required chemical fertilisers (which depleted soil microbiomes), pesticides (which killed pollinators and contaminated groundwater), and massive irrigation (which exhausted aquifers that took thousands of years to fill). The Punjab, which led the revolution, now has groundwater tables falling by 1 metre per year in some districts. The crops it displaced — finger millet, pearl millet, sorghum, foxtail millet — required none of these inputs and are adapted to precisely the semi-arid conditions that climate change is making more common across India.
“A farmer growing sorghum in Solapur uses 80% less water than a farmer growing wheat in the same region, pays nothing for fertiliser (millet builds its own soil fertility), and faces no pest pressure requiring pesticide. The only thing working against millets is the market.”
The nutrition case is equally strong
Millets as a category outperform rice and wheat on almost every nutritional metric: higher protein (9–12% vs. 7% for polished rice), higher fibre (8–14g vs. 0.4g for polished rice), dramatically higher mineral content (finger millet has 344mg calcium — more than milk), and lower glycemic index (GI 50–65 vs. 72 for polished white rice). India's twin epidemics of anaemia (53% of women) and type 2 diabetes (77 million) both have a clear dietary correlation with the replacement of millet by polished rice and refined wheat flour.
- Start with foxtail or little millet — they cook fastest (15–18 minutes) and have the mildest flavour.
- Replace 50% of white rice with a millet in khichdi — flavour barely changes, nutritional profile transforms.
- Ragi flour in dosa batter (1:3 ragi to rice) is the standard Karnataka approach — calcium and iron increase dramatically.
- Buy direct from small farmers when possible — millet grown without inputs is genuinely different from conventionally produced millet.
