Every day, Ram Lal Kariyam checks the river stream that flows through Salhi, his village in the Hasdeo Arand forest of Chhattisgarh. He is on the lookout for any brown slurry from the coal-washing facility of the sprawling mine nearby.
“Earlier they would discharge dirty water four times a week,” said the 28-year-old farmer, a member of India’s Gond tribe. “Now it’s rare.” Driving this improvement are forest dwellers like him, who consistently monitor the coal mine for environmental violations.
The central state of Chhattisgarh produced the highest quantity of coal in India in the last financial year. Most of its mines are open-cast—the ground on top has to be destroyed as the coal beneath is too shallow for underground mining. It leads to greater air pollution due to the blasting of land as well as loading and unloading of overburdened soil.
