The 100,000 Sacred Groves of India – and why they may be the world’s most efficient nature reserves.

No fences, no rangers, no budget. India’s sacred groves have been running the world’s most efficient nature reserves for centuries.
India’s farmers forecasted the monsoon long before satellites existed. One of them told me exactly how.

I spent a day with a 74-year-old farmer near Barmer who predicted the 2022 monsoon better than the regional IMD forecast. No instruments. No app. Just a tree, some ants, and four generations of accumulated observation. It changed how I think about climate knowledge entirely.
