A villager looks at the changing landscape due to coal mines at Kosampalli-Sarasmal panchayat in Raigarh district, Chhattisgarh. Air, water, soil and sediment samples indicated high levels of 12 toxic metals in a study on the health and environmental impact of coal mining on three villages in the district.
In Sarasmal--a village in north Chhattisgarh’s Raigarh district, about 260 km from the state capital Raipur--296, or 87%, of the 341 respondents living near coal mines suffered from one or more illness, including loss of hair, conditions affecting muscles, bones and skin, and dry cough, according to a study on the health and environmental impact of coal mining.
The study, published on November 16, 2017, focused on health problems of long-term residents--rather than of workers--living adjacent to, or within 2 km of, coal mines and coal-fired power plants.
Medical and environmental professionals conducted the study in May 2017, in partnership with People First Collective, India, an environmental forum, and the Adivasi Dalit Mazdoor Sangathan, a social organisation. The survey included 515 people in 132 households, across three villages--82 in Sarasmal, 27 in Kosampalli and 23 in Dongamouha. About 205 adults and children--78 from Sarasmal, 39 from Kosampali and 88 from Dongamouha--attended medical check-ups between May 22 and 24, 2017.

How mining affected three tribal Chhattisgarh villages
Sarasmal and Kosampalli are predominantly tribal (68% and 85%, respectively), while Dongamouha is mostly inhabited by backward classes.
Before mining began, Kosampalli was accessible by roads on all sides but is now cut off on three sides by surface mining operations. Villagers have to cross the river Kelo by foot to access the main road or travel to a nearby market, the study said.
More than 100 earning members from 240 families of the Kosampalli-Sarasmal panchayat have died from respiratory and other health diseases in the last two decades, India Water Portal reported on March 30, 2017.
On average, one-third of the respondents in all three villages were underweight.
Air, water, soil and sediment samples indicated high levels of 12 toxic metals: Aluminium, arsenic, antimony, boron, cadmium, chromium, lead, manganese, nickel, selenium, vanadium and zinc. Arsenic and cadmium are carcinogens while excess of boron can damage the testes, intestines, liver, kidney and brain. Chromium causes respiratory problems such as asthma and lung cancer, and an excess of selenium leads to neurological conditions including paralysis and even death.
Most health complaints in Sarasmal village were reported by women. They suffered from 58% of all stomach-related ailments, and 91% of kidney-related ones. Of the 228 respondents who suffered from at least one combination of complaints related to hair, skin, eye or joint issues, 16% experienced at least three medical conditions and 36% experienced at least two.
Of the 193 reporting skin, joint or stomach complaints, 19% complained about all three while 23% reported two. Of the 127 who reported a cough, 71% said they had dry cough, which is often a symptom of asthma.
About a third of the 103 complaints of musculoskeletal problems in Sarasmal were from people less than 30 years old.
Despite living close to coal mines, less than 10% of households used coal for cooking. Most depended on firewood or cow dung, a cause of indoor air pollution which can result in premature death from illnesses like pneumonia, stroke and lung cancer, according to the World Health Organization.

Mining affected livelihoods, crop yield
Over 70% of surveyed households in all three villages, where farming is the main occupation, complained that crop yield was poor. Of the 82 households in Sarasmal village, 45% no longer depended on agriculture because of low crop yield, the study found.
Coal mines have been a contentious issue in these villages with villagers losing land to the Gare Palma coal mines in mining blocks IV/2&3. The ownership of these blocks is disputed after the Delhi high court upheld the government’s 2015 decision to cancel Jindal Steel and Power Ltd’s bids for coal blocks in the district of Raigarh, online news portal The Wire reported on September 10, 2017. Dongamouha village is adjacent to Jindal’s Dongamouha power plant.
Tribal villagers have also been protesting against opening new mines and shutting down the old ones as they do not want to give up their land, the Wire report said.
To mitigate the effects of mining, the government implemented the Pradhan Mantri Khanij Kshetra Kalyan Yojana (Prime Minister’s Development Programme for Mining-Affected Regions) in 2015 for the welfare of areas and people affected by mining-related operations, by creating a corpus for local area development from a levy on all mining operations.
In Raigarh district of Chhattisgarh, the district mining fund had collected Rs 52 crore till February 2017, according to a report from the Centre for Science and Environment, a New Delhi-based advocacy. The district plans to spend this money mainly on energy and watershed development (23.2%), physical infrastructure (14.9%) and skill development (11.2%).
