1. Odisha’s Mineral Endowment: The Scale of What Lies Beneath

1.1 National Share and Production Value

Odisha controls a disproportionate share of India’s mineral wealth relative to its 4.74% share of national land area:

Chromite95—98%~111 million tonnesJajpur (Sukinda Valley), Dhenkanal, Keonjhar
Nickel~92%Data limitedJajpur, Keonjhar

Coal~24%~51,571 million tonnesAngul (Talcher), Jharsuguda (Ib Valley)
ManganeseNational rank 1—2~116 million tonnesSundargarh, Keonjhar, Rayagada, Balangir

[Government of Odisha, Department of Steel and Mines; IBM State Report; Odisha PCS Notes]

Production share note (Survey 2025-26): The reserves shares above are not the same as production shares. By production volume in 2024-25, Odisha contributed 100% of India’s chromite, 72.7% of bauxite, 55% of iron ore, 26% of coal, and 16% of manganese ore (rank 4) (Economic Survey 2025-26, Ch. 5 §5.6.3, Figure 5.33). The state’s overall share of national mineral production by value rose from 36.9% in 2020-21 to 43.7% in 2024-25 — the largest in India (Ch. 5 §5.6.1, Figure 5.32).

Production value: The total value of minerals produced in Odisha reached Rs 64,785 crore in 2024—25, up from Rs 30,044 crore in 2020—21. Coal, bauxite, chromite, iron ore, manganese ore, and limestone together contributed approximately 99% of total mineral production value. By 2024—25, Odisha accounted for 43.7% of India’s total value of mineral production (metallic and non-metallic, excluding fuel oil and atomic minerals) — the single largest mineral-producing state in the country. (Economic Survey 2025-26, Ch. 5 §5.6)

Growth trajectory: The value of mineral production recorded a compound annual growth rate of 21.2% between 2020—21 and 2024—25 — the highest among major mineral-producing states except Maharashtra. (Economic Survey 2025-26, Ch. 5 §5.6)

Mining leases: Odisha has over 2,195 active and dormant mining leases spread across 998.26 sq. km (approximately 0.64% of the state’s total geographical area). The actual area affected by mining — including overburden dumps, tailings ponds, haul roads, townships, and downstream pollution zones — is substantially larger than the lease area itself. [Government of Odisha, Department of Steel and Mines]

Revenue dependence: Mineral revenue is the largest single source of Odisha’s non-tax revenue, contributing nearly 80% of the state’s non-tax revenue in 2024-25. The state collected a record ₹42,000+ crore in mineral revenue in 2024-25, up from earlier-year estimates of ~Rs 43,444 crore in 2022-23. As of Q2 of FY 2025-26 (provisional), Odisha had already collected about ₹20,000 crore in mineral revenue (Economic Survey 2025-26, Ch. 5 §5.6.6). For broader context on the 6-8% of GSDP framing and the 171% surge in 2021-22 that produced a fiscal surplus, see [PRS India, Odisha Budget Analysis 2023-24].

1.2 The Mineral-Forest-Tribal Overlap

The critical ecological fact about Odisha’s mineral endowment is that the minerals sit beneath forests, and the forests are inhabited by tribal communities. This is not coincidence but geology: the Eastern Ghats and the Singhbhum Craton — the geological formations that concentrated mineral deposits — also created the forested, hilly terrain that was historically resistant to state penetration, enabling both dense forest cover and autonomous tribal governance systems for millennia.

The triple overlap:

Mineral BeltKey DistrictsForest TypeTribal Communities
Iron Ore Belt (Joda-Barbil corridor)Keonjhar, Sundargarh, MayurbhanjTropical dry deciduous, sal forestsHo, Santhal, Munda, Bhuyan, Juang, Kolha
Chromite Belt (Sukinda Valley)Jajpur, KeonjharTropical moist deciduousBhuyan, Juang, Santal
Bauxite Belt (Koraput-Rayagada plateau)Koraput, Rayagada, KalahandiTropical semi-evergreen, hill forestsKondh (Dongria, Kutia), Paraja, Gadaba, Bonda
Coal Belt (Angul-Talcher, Ib Valley)Angul, JharsugudaTropical dry deciduousVarious (smaller populations)
Manganese BeltSundargarh, KeonjharDry deciduous, salBhuyan, Munda, Oraon

More than 50% of the state’s tribal population resides in six districts — Mayurbhanj (15.43% of state ST population), Sundargarh (11.08%), Keonjhar (8.54%), Koraput (7.27%), Nabarangpur (7.10%), and Rayagada (5.65%) — which are also the primary mineral extraction zones. Approximately half of Odisha’s geographical area falls within Fifth Schedule territory. [Census 2011; Presidential Order 1977]

Odisha’s forest cover: According to ISFR 2023 (the latest report), Odisha’s combined forest and tree cover stands at 58,597 sq km — 37.6% of the state’s total geographical area (155,707 sq km). Forest area alone is 52,434 sq km (33.7%) and tree cover is 6,163 sq km (3.9%). Between 2021 and 2023, Odisha added 559 sq km of forest and tree cover — the third highest national rise. The mining districts of Keonjhar, Sundargarh, Koraput, Rayagada, and Kalahandi all have significant forest cover that directly overlaps with mineral deposits (Economic Survey 2025-26, Ch. 3 §3.11.4).

The consequence: every major mining operation in Odisha simultaneously destroys forest, displaces tribal communities, and degrades the ecosystem services (water, soil, biodiversity, climate regulation) that those communities and downstream populations depend on. The ecological cost cannot be separated from the social cost — they are two dimensions of the same extraction.

2. Deforestation from Mining

2.1 Forest Diversion Under the Forest Conservation Act

Since the enactment of the Forest Conservation Act (1980), Odisha has diverted over 62,016 hectares of forest land for non-forestry purposes, with mining as the single largest driver of diversion. During this process, approximately 1.95 million trees were felled. Between 2008—09 and 2022—23, mining projects accounted for the largest category of forest land diversion nationally, with approximately 60,000 hectares diverted across India for mining alone. [Business Standard, 2023; Factly]

Odisha is among the top four states for forest diversion alongside Punjab, Madhya Pradesh, and Telangana — these four states account for approximately half of India’s total forest land diversion over the last fifteen years. From 2015 to 2019 specifically, 4,968.48 hectares of forest land were diverted for non-forestry purposes in Odisha. Between April 2019 and March 2024, a further 95,724.99 hectares were approved nationally under the Van (Sanrakshan Evam Samvardhan) Adhiniyam, 1980. [Factly; MoEFCC; PIB]

District-level diversion:

DistrictForest Land Diverted (ha)Primary Purpose
Keonjhar~14,466Iron ore, manganese, chromite mining
Sundargarh~10,025Iron ore, manganese mining
Angul~6,800Coal mining, thermal power plants
SambalpurSignificantCoal mining, industrial
JajpurSignificantChromite mining, steel plants

Over 2 lakh trees were felled in Keonjhar and Sambalpur districts alone, with over 1 lakh trees cut in Angul. [Business Standard, 2023]

Recent clearance applications: In March 2026, the Odisha government approached the Centre seeking approval for diversion of 216.875 hectares of forest land in Keonjhar district for exploration of an iron ore block allotted to Tata Steel Ltd — indicating that the pace of forest diversion for mining continues unabated. [Business Standard, 2026]

2.2 Satellite Data on Forest Cover Loss in Mining Corridors

Keonjhar and Sundargarh (2000—2024): A spatio-temporal analysis using landscape metrics found that forest coverage in Sundargarh and Keonjhar districts decreased from 30.69% in 2000 to 24.55% in 2024, while non-forest areas expanded from 69.31% to 75.45% — a loss of approximately 6 percentage points of forest cover in 24 years. [Journal of Resources and Ecology, 2025]

NDVI-based assessment (2020—2024): A study using Normalized Difference Vegetation Index satellite data found that nearly half of the total canopy loss between 2020 and 2024 is concentrated in Keonjhar (4,700 ha) and Sundargarh (4,200 ha), with Jajpur (3,100 ha) forming a significant secondary hotspot. Fragmentation analysis showed significant deterioration in forest health, characterised by increasing edge effects and shrinking core habitats. [Preprints.org, 2025]

Joda-Barbil iron ore belt (Keonjhar): The Joda-Barbil region — the heart of Odisha’s iron ore mining — has experienced severe deforestation since 1980. Classification results from remote sensing indicate a significant decline in forest land (annual decline rate of 0.56%), water bodies (0.47%), and cropland (0.87%), with corresponding increases in built-up and mining areas. Due to deforestation in the hills, 80% of streams have gone dry, and water flow in Keonjhar’s waterfalls has decreased by 50% in the last 10 years. The mining area lost its “past green corridor” and experienced a constant average surface air temperature rise of 1—2 degrees C between 2007 and 2018. [JETIR, 2020; ResearchGate]

Remote sensing case study (2001—2019): A peer-reviewed study documented direct correlation between mining operations and forest loss patterns in Odisha, with spatial analysis confirming that forest cover changes are clustered around mining and developmental activities. [Journal of Environmental Management, ScienceDirect, 2021]

Global Forest Watch data: According to Global Forest Watch, Odisha has experienced significant tree cover loss across its mining districts, with UMD satellite data capturing disturbances to woody vegetation at least five meters tall from 2001 to 2024. [Global Forest Watch]

2.3 The Five Mining Corridors

1. Joda-Barbil Iron Ore Belt (Keonjhar-Sundargarh): Runs along the northern border of Odisha, stretching from the Gorumahisani hills of Mayurbhanj through Keonjhar and Sundargarh to Singhbhum in Jharkhand. The belt hosts India’s largest iron ore concentration with mines operated by Tata Steel, SAIL, OMC, and multiple private lessees. Forest diversion here is the highest of any district in Odisha (~14,466 ha). The Joda-Koira mining sub-belt shows progressive degradation from dense forest to open forest to scrub. [JETIR, 2020; FSI]

2. Sukinda Chromite Valley (Jajpur): Contains 95—98% of India’s chromite reserves across approximately 200 sq km. Open-cast chromite mines have stripped vegetation from the valley floor and hillsides, exposing laterite soils to erosion and the chromite ore body to weathering that generates hexavalent chromium. Forest diversion here is compounded by the proximity to the Kalinganagar industrial growth centre. [Government of Odisha; IBM]

3. Angul-Talcher Coal Belt: The Talcher Coalfield alone holds reserves of 38.65 billion tonnes — the highest of any single coalfield in India. MCL operates 15 open-cast mines that have progressively stripped the landscape. Coal mining by its nature requires removal of all vegetation and overburden, creating vast open pits that permanently alter topography. The concentration of thermal power plants (NTPC Talcher Kaniha 3,000 MW, NALCO CPP 1,200 MW, and multiple IPPs) adds ash pond footprints to the mining footprint. [MCL; Geological Survey of India]

4. Jharsuguda-Ib Valley Coal Cluster: Covers Jharsuguda and Sundargarh districts. The coalfield supplies Vedanta’s aluminium smelter (world’s largest), OPGC’s Ib Thermal Power Station (1,740 MW), and multiple captive power plants. The combined coal mining plus industrial footprint creates continuous deforestation across the landscape. [MCL; Global Energy Monitor]

5. Koraput-Rayagada Bauxite Plateau: The bauxite-capped plateaus of the Eastern Ghats in Koraput and Rayagada districts are biologically rich hill forests inhabited by Dongria Kondh, Kutia Kondh, Paraja, and other tribal communities. Forest losses in Koraput and Rayagada range from 10 to 20%. Active mining at Kodingamali (OMC, 435 ha forest clearance obtained in 2017), pending operations at Sijimali (Vedanta, 700+ hectares forest diversion sought), and the rejected Niyamgiri (Vedanta) project define this corridor. The Mali Parbat mine (Hindalco) affects 44 villages under multiple panchayats. [Scroll.in; Mongabay India; Down to Earth]

2.4 CAMPA Fund: Money Collected, Trees Not Planted

The Compensatory Afforestation Fund Management and Planning Authority (CAMPA) was designed to compensate for forest diversion by funding afforestation elsewhere. Mining companies and project proponents are required to pay the Net Present Value (NPV) of diverted forest land into the CAMPA fund.

The reality:

  • Odisha’s CAMPA fund had accumulated Rs 4,570 crore in interest alone by recent count, indicating a massive principal. [Mongabay India, 2025]
  • Only 60% of diverted forest land had been actually reforested. [Mongabay India, 2025]
  • Plantation survival rate: 7.5% from 2016—17 to 2019—20 due to non-maintenance. Of the trees planted as compensation, barely 1 in 13 survived. [CAG Audit]
  • Rs 248.06 crore was diverted from CAMPA funds (2019—20 to 2021—22) to Ama Jangala Yojana (AJY), a state flagship programme — meaning compensatory afforestation money was redirected for a different purpose. [CAG Audit]
  • Of 47,84,180 seedlings procured for CAMPA plantation (costing Rs 8.13 crore), 15,45,945 were diverted to other plantation schemes like MGNREGA and Odisha Forestry Sector Development Project — indicating systematic misallocation. [CAG Audit]
  • The Enforcement Directorate raided forest officials in Kalahandi and traced Rs 2.5 crore of CAMPA money through bogus vouchers to dummy accounts — indicating outright financial fraud. [Mongabay India, 2025]
  • The record number of forest diversions occurred in 2023, even as CAMPA spending declined nationally. [SabrangIndia]

The structural problem: Even where CAMPA plantations succeed, they cannot replicate the ecological complexity of the natural forest that was destroyed. A monoculture teak or eucalyptus plantation on degraded land is not ecologically equivalent to a multi-layered sal forest with centuries of accumulated soil biota, understorey diversity, mycorrhizal networks, and hydrological functions. CAMPA treats forests as fungible units of tree cover. Ecology does not.

3. Water Pollution

3.1 Hexavalent Chromium in Sukinda Valley

The Sukinda Valley in Jajpur district hosts 95—98% of India’s chromite deposits and was ranked as the fourth most polluted place in the world by the Blacksmith Institute (now Pure Earth) in September 2007. TIME Magazine featured it among the world’s top ten most polluted places. [Blacksmith Institute/Pure Earth, 2007; TIME, 2007]

Scale of contamination:

  • Approximately 70% of surface water and 60% of drinking water in the Sukinda mining area contain hexavalent chromium (Cr VI) at concentrations exceeding double the national and international standards. [Blacksmith Institute; ScienceDirect, 2023]
  • Groundwater chromium levels have been found up to 14 times above the permissible limit in the most recent monitoring. [OrissaPOST, 2024]
  • 2.3 million people are affected through dependence on the Brahmani River system contaminated by Sukinda mining runoff. [ScienceDirect, 2023]
  • Over 30 million tonnes of waste rock are spread over the surrounding areas and the Brahmani riverbanks. [Pure Earth]
  • 12 mines operated without any environmental management plans. [Pure Earth]

The Brahmani River contamination: Mining companies draw clean water from the Brahmani River and release toxic effluents into the Damsala stream, which flows into the Brahmani. The Damsala Canal receives potentially toxic elements (PTEs) from mining effluents, contaminating surface water, groundwater, and soil. Trace metals including Fe, Mn, Ni, Co, Pb, Zn, Cu, Cr, and Cd have been measured in the Brahmani-Baitarani river complex and Dhamara estuary at levels exceeding WHO and USEPA recommendations. About 2.6 million people depend on the Brahmani River for water and sustenance. [Pure Earth; Springer; Nature Scientific Reports, 2025]

Health effects: Hexavalent chromium (Cr VI) is classified as a Group 1 carcinogen by IARC. Documented health impacts in Sukinda include gastrointestinal bleeding, tuberculosis, asthma, infertility, birth defects, stillbirths, skin ulcers, kidney ailments, elevated cancer risk, and fatalities. An Indian health group estimated that 84.75% of deaths in mining areas and 86.42% of deaths in nearby industrial villages were attributed to chromite-mine-related diseases. [ScienceDirect, 2023; PMC, 2011]

Agricultural contamination: Elevated concentrations of potentially toxic metals have been found in farmland soils near Sukinda, with contamination entering the food chain through paddy cultivation — the staple crop of the region. [ScienceDirect, 2023]

Timeline of inaction: Despite documentation since the early 2000s, international attention since 2007, and repeated government promises, no comprehensive remediation has been undertaken. In 2024, the National Green Tribunal had to order the Odisha government to provide clean drinking water to Sukinda Valley residents after a Joint Committee report confirmed ongoing chromium contamination in groundwater. That an NGT order was required for something as basic as clean water — in a state earning tens of thousands of crores from the very mines causing the contamination — is itself the indictment. [Down to Earth; IAS Gyan, 2024]

3.2 Acid Mine Drainage in Coal Mining Areas

Acid mine drainage (AMD) — the generation of sulphuric acid and dissolved metals when sulphide minerals are exposed to oxygen and water during mining — is a growing concern in Odisha’s coal regions.

Talcher-Angul groundwater contamination: Studies of surface water and groundwater around the Talcher Coalfield found significant water quality degradation. Coal mining and ancillary activities have caused water pollution characterised by extreme pH conditions, heavy metal contamination, and elevated fluoride (up to 4.4 mg/L, attributed to mining activities). Water Quality Index values indicate many sources unsuitable for drinking. Annually, 86.26 million cubic metres of water are drawn from the Brahmani River and its tributaries for industrial or mining activity in the Angul-Talcher region alone. [SCIRP; SAGE Journals, 2017; Springer]

Ib Valley water quality: Hydrogeochemistry and surface water quality assessment of the Ib Valley coalfield area document contamination from coal mining runoff. [ResearchGate]

Persistent contamination: At abandoned mines in Jharkhand and Odisha, AMD continues to flow from mines closed over 50 years ago — demonstrating that AMD contamination is essentially permanent on human timescales. [Nature Scientific Reports, 2025]

3.3 Fly Ash from Thermal Power Plants

The thermal power plants clustered around Odisha’s coalfields generate massive volumes of fly ash — the non-combustible residue of coal burning — containing toxic heavy metals including arsenic, mercury, lead, and cadmium.

NTPC Talcher Kaniha (3,000 MW): Generates approximately 23,000 tonnes of ash daily. In June 2011, the ash pond developed cracks at several places and burst at one location. Approximately 5,000 villagers of Derenga in Kaniha block have been demanding mass displacement for 15 years due to ash pollution. NTPC eventually began dumping ash in an abandoned coal mine as a disposal solution. [Business Standard, 2010; Daily Pioneer, 2018; Global Energy Monitor]

Vedanta Jharsuguda (3,615 MW captive power plant): In August 2017, a breach in the embankment of Vedanta’s ash pond near Katikela village released toxic fly ash slurry across agricultural lands, into the river, village areas, and plant-side wetlands, causing “colossal environmental and ecological damage.” The SPCB Odisha suspended operations of five power plant units. Fly ash from Jharsuguda operations has also been found contaminating the Hirakud Dam reservoir — the state’s most important irrigation and power infrastructure. Fly ash was dumped on forest lands, agricultural lands, near water bodies, and even behind the offices of the District Magistrate and Superintendent of Police. [Down to Earth, 2024; The Statesman; Vedanta Compliance Report]

OPGC Ib Thermal Power Station (1,740 MW): Located in Jharsuguda, with plans for 1,320 MW expansion. Ash disposal remains a persistent challenge across the Ib Valley cluster. [OPGC; Global Energy Monitor]

NALCO Captive Power Plant (1,200 MW, Angul): Generates fly ash that adds to the cumulative ash burden of the Angul-Talcher corridor. [NALCO]

CSE analysis: India’s thermal power ash management amounts to an “ashen legacy,” with Odisha among the worst-affected states due to concentration of thermal capacity without adequate ash utilisation infrastructure. [CSE India]

3.4 Vedanta Lanjigarh Red Mud Pond

The Vedanta alumina refinery at Lanjigarh in Kalahandi district has been a recurring source of toxic waste contamination.

September 2024 breach: On September 15, 2024 at approximately 2:00 AM, a breach occurred in the dyke wall of the Process Water Lake associated with the red mud disposal facility. The incident released nearly 4 lakh (400,000) cubic metres of highly alkaline and toxic wastewater that spread across adjoining agricultural lands, entered the Vamsadhara (Bansadhara) River, affected hundreds of acres across more than 50 villages under six gram panchayats, and caused death of fish, snakes, frogs, crabs, and other aquatic life. [Down to Earth; Countercurrents, 2026; Odisha Barta; AlCircle]

A previous leak of red mud into the Vamsadhara River was documented by Down to Earth in 2013, indicating a recurring problem. [Down to Earth, 2013]

The National Green Tribunal admitted a plea regarding the 2024 breach in March 2026, with the next hearing scheduled for May 2026. Over a year after the incident, no environmental compensation had been imposed or recovered from the company. [Countercurrents, 2026; TheNewsInsight]

3.5 Groundwater Contamination Near Mine Sites

Kalinganagar industrial area (Jajpur): Studies evaluating 76 groundwater samples found fluoride exceeding WHO limits in 36.8% of samples and nitrate exceeding limits in 11.84% of samples. Kalinganagar was ranked 84th among India’s most polluted cities. [Springer, 2024; ResearchGate]

Baitarani River contamination: The Baitarani River, draining the iron ore mining belt of Keonjhar, accumulates mining discharges alongside domestic effluents. Heavy metal bioaccumulation has been documented in commercially important fish species, with ecological and human health risk assessments indicating contamination of the food chain. [Springer, 2025; ScienceDirect, 2023]

4. Air Pollution

4.1 Angul-Talcher-Jharsuguda Corridor: Critically Polluted

The Angul-Talcher region is classified by CPCB as one of India’s 24 Critically Polluted Areas with a Comprehensive Environmental Pollution Index (CEPI) score of 82.09 — the highest among the 4 CPAs in Odisha and among the highest nationally. The Ib Valley-Jharsuguda cluster also scores above 70 (critically polluted threshold). [CPCB; SPCB Odisha; LIFE India]

Industrial density in Angul-Talcher: 69 red-category, 94 orange-category, and 17 green-category industrial units, including aluminium smelters, thermal power plants (total ~6.7 GW in Angul alone), iron and steel smelters, coal washeries, ferro alloy plants, and sponge iron units. [LIFE India; iFOREST]

PM2.5 and PM10 data: Air quality data from CPCB continuous monitoring stations in Talcher and Brajrajnagar (January 2019 to December 2023) document persistent exceedances of national ambient air quality standards for PM2.5, PM10, NOx, NO2, SO2, and O3. PM10 and PM2.5 levels in Talcher and Angul frequently exceed permissible limits by 3—5 times. [Frontiers in Environmental Science, 2025; CPCB data]

Machine learning health risk analysis: A study using machine learning models to estimate criteria pollutants found substantial premature mortality attributable to: PM2.5 (16—26%), PM10 (31—43%), NO2 (15—21%), SO2 (4—7%), and O3 (3—6%) across the coal mine complex belt of eastern Odisha. Talcher showed greater health risks, with pollutant exposure linked to up to 6% higher risk for PM10, 5% for NO2, and up to 3% for SO2 compared to baseline populations. [Frontiers in Environmental Science, 2025; MDPI Atmospheres, 2022]

Talcher as India’s most polluted: During winter 2024, Talcher emerged as one of India’s most polluted places, with severe smog choking the region. The Angul-Talcher industrial area is now recognized as a major global emission hotspot. [OmmCom News; Frontiers]

Jharsuguda-Ib Valley cluster: The cluster covers approximately 580 sq. km with a population of approximately 3 lakh. SPM and PM10 concentrations exceed national ambient air quality standards for both residential and industrial areas. Large amounts of SO2, NOx, and particulate matter are released daily from mining and metallic industries in Jharsuguda and Sambalpur. Jharsuguda hosts approximately 5.7 GW of installed thermal capacity. [IOSR Journals; SPCB Odisha; iFOREST]

4.2 CPCB/SAFAR Monitoring and NCAP Status

Non-attainment cities under NCAP: Odisha has six non-attainment cities: Bhubaneswar, Cuttack, Rourkela, Talcher, Angul, and Balasore. Kalinganagar is monitored as a seventh polluted city. [SPCB Odisha; NCAP]

Reduction targets: Angul-Talcher and Rourkela must reduce PM10 by 39—45% and PM2.5 by 14—30% from baseline to meet clean air standards. [LIFE India; CSE India]

Progress: Talcher has shown a 39% reduction in PM10 (177.1 to 106.9 ug/m3), making it one of the better-performing NCAP cities. However, the national NCAP missed its 2024 targets overall. [CSE India; Down to Earth]

Comprehensive Action Plan: The Odisha State Pollution Control Board has prepared action plans for Angul-Talcher, but implementation capacity remains constrained. [SPCB Odisha]

4.3 Coal Dust from Open-Cast Mines and Vehicular Emissions

The coal transport corridor from Talcher and Ib Valley mines to Paradip port and industrial consumers creates a linear belt of particulate pollution stretching hundreds of kilometres.

Coal dust on agriculture: Coal dust has caused paddy crops to turn black, rendering them unfit for sale. Leafy vegetables covered in black dust are neither edible nor marketable. Farmers report declining yields over years of exposure. [Down to Earth, 2023]

Vehicular emissions: Heavy mining trucks operating on unpaved or poorly maintained roads create linear dust corridors connecting mines to railheads, ports, and processing plants. Villages along transport routes face continuous dust exposure. Stone crusher units across the mining belt operate with inadequate dust suppression. [Down to Earth, 2023; EcoInSEE]

The compound effect: When coal mines, thermal power plants, aluminium smelters, sponge iron units, coal washeries, and ferro alloy plants are concentrated in the same airshed, the cumulative pollution exceeds what any individual source assessment would predict. Angul-Talcher’s CEPI score of 82.09 reflects this compound effect. A 300-household study found that 90% of households in mining villages reported health problems, compared with 52% in non-mining villages approximately 47 km away. [Mishra, 2015; SAGE Journals, 2017]

Pollution so severe that villagers demand displacement: In a reversal of the typical pattern (where communities resist mining displacement), villagers in the Talcher area have demanded to be displaced and relocated due to unbearable pollution. [Daily Pioneer, 2018]

5. Biodiversity and Wildlife Impact

5.1 Elephant Corridor Disruption

Odisha is a critical state for Asian elephant conservation, with the 2024 winter census recording 2,103 elephants (474 males, 1,030 females). However, mining is systematically destroying elephant habitat and migration corridors. [Elephant Census 2024]

Keonjhar — the epicentre of the crisis:

  • In the last 40 years, the highest diversion of forest land for mining — 10,451 hectares — has taken place in Keonjhar district. [Outlook India]
  • Mining in Keonjhar has affected nearly 530 villages through human-elephant conflict. [Outlook India]
  • Keonjhar had 112 elephants in 2002 but only 40 elephants at some point due to habitat destruction from large-scale mining — a catastrophic population crash. Most elephants did not die; they migrated permanently to other regions, scattering into unfamiliar territory and intensifying conflict elsewhere. [Outlook India; Frontiers]

Human-elephant conflict casualties:

  • Between 2017 and 2022, Odisha recorded 499 human deaths from human-elephant conflict — the highest in India for this period. [Down to Earth]
  • Between 2010 and 2019, 104 people were killed in Angul and Athmalik forest divisions alone. [Frontiers]
  • Dhenkanal alone witnessed 130 elephant deaths and 227 human deaths over the last decade. [Down to Earth, 2021]
  • Odisha, Jharkhand, West Bengal, and Assam accounted for almost 70% of human fatalities from elephant encounters between 2009 and 2024. [Frontiers in Conservation Science, 2026]
  • The iron ore-rich districts of Angul, Deogarh, Keonjhar, and Dhenkanal top the list for conflict intensity. Canal construction in Angul has divided the region, trapping elephants. [Down to Earth]

Elephant mortality: Odisha recorded 345 elephant deaths over recent years, with electrocution responsible for 221 deaths (64%) and poaching for 66 deaths. On average, 81 elephants die every year in the state. [Conservation India]

Corridor status: Of the 14 proposed elephant corridors in Odisha, many remain unnotified and degraded by mining and industrial activity. The Hadargh-Kuldiha-Similipal Corridor is ecologically viable only if mining is stopped.

5.2 Simlipal Buffer Zone and Wildlife Corridor Threats

Simlipal Biosphere Reserve in Mayurbhanj district — covering 5,569 sq km (core: 845 sq km, buffer: 2,129 sq km, transition: 2,595 sq km) — is a UNESCO Biosphere Reserve hosting:

  • 42 species of mammals including tiger, leopard, Asian elephant, gaur, and the globally unique melanistic (black) tiger
  • 242 species of birds, 30 species of reptiles
  • 1,076 species of vascular plants, 93 orchids, ~300 medicinal plants, 52 endangered flora species [WWF India; Wikipedia; NTCA]

Mining threats: Illegal stone mining within Simlipal’s eco-sensitive and buffer zones causes dust pollution and habitat degradation. [TheNewsMill, 2025; Down to Earth, 2019]

Similipal-Satkosia corridor: A 2025 study of the corridor forest linking Similipal and Satkosia Tiger Reserves documented 128 tree species, 47 shrub species, and 56 herb species, with average above-ground biomass of 130.5 Mg/ha. The corridor supports high diversity despite mining pressures, but continued expansion of mining and infrastructure threatens irreversible damage. The study recommended urgent protection under the Wildlife (Protection) Act, 1972. [ScienceDirect, 2025]

Satkosia Tiger Reserve (Angul): The Diatari iron ore mining lease of OMC covers 1,018.3 hectares (846.4 ha forest land) in the vicinity of Satkosia. The habitat supports Schedule 1 species including Indian elephant, Indian wolf, mouse deer, sloth bear, sambar, king cobra, and large Bengal monitor lizard. [Down to Earth, 2019]

Karlapat Wildlife Sanctuary (Kalahandi): The Karlapat bauxite block shares its border with the sanctuary. Mining would dry up 300 large and small streams flowing from the sanctuary, destroying watershed function that sustains downstream agriculture. [IAS Gyan; Polis Project]

5.3 Species-Specific Impacts and Broader Biodiversity Loss

The pattern across all mining districts: open-cast mining removes forest cover, fragments habitats, disrupts migration corridors, alters drainage patterns, generates noise and vibration, and eliminates the understorey vegetation, soil biota, and microhabitats that support the majority of biodiversity. Impacts include:

  • Amphibians and reptiles dependent on stream habitats destroyed by siltation
  • Pollinator species affected by dust deposition on flowering plants
  • Soil organisms destroyed by overburden removal
  • Aquatic invertebrates and fish killed by sedimentation, heavy metals, and pH changes
  • Bird species dependent on mature forest canopy for nesting
  • Medicinal plants and NTFPs sustaining tribal livelihoods

The watershed destruction pattern: Bauxite-capped plateaus of Koraput, Rayagada, and Kalahandi act as natural water towers — their porous laterite surfaces absorb monsoon rainfall and release it through hundreds of perennial streams. When bauxite is mined, the water-storage capacity is destroyed. The Niyamgiri Hills support over 300 perennial streams feeding the Vamsadhara and Nagavali river systems. The streams exist because the bauxite cap exists; remove the bauxite and the streams die.

Invasive species: Mining-disturbed landscapes are colonised by Lantana camara, Chromolaena odorata, and Prosopis juliflora, preventing natural forest regeneration.

No cumulative assessment: No comprehensive biodiversity impact assessment has been conducted for the cumulative effects of mining in Odisha. Individual EIAs assess single projects in isolation; the cumulative landscape-level impact is never formally assessed.

6. Governance Failures

6.1 EIA Process Manipulation

Structural dilution:

  • The 2020 draft EIA notification proposed expanding categories exempt from public hearing requirements
  • Coal mine capacity expansions of up to 40% exempted from public hearing [Down to Earth]
  • Strategic mineral mining projects exempted from public hearing under EIA [Vision IAS, 2025]
  • “Legacy mining cases” (mines operating without clearance) given eased rules rather than enforcement [Mongabay India, 2021]

Specific Odisha cases:

  • POSCO: EIA described as “in a hurry and grossly defective.” The Meena Gupta Committee recommended cancelling the environmental clearance, but the Ministry granted it anyway. [Khurana & Khurana, 2025]
  • Vedanta Niyamgiri: EIA “grossly downplayed socio-cultural effects and failed to consult affected populations sufficiently.” Public hearings viewed as “superficial.” [Khurana & Khurana, 2025]
  • Vedanta Jharsuguda coal project: Public hearing conducted despite known EIA shortcomings. People physically barred from attending, scuffling with police. [NewsClick]
  • Sijimali bauxite mine: Public hearings conducted “following mass arrests, illegal detentions, police raids and disruptions of assemblies of affected communities, creating an environment of fear, duress and intimidation.” Villagers accused Vedanta of “spreading misinformation” at hearings. Between August and September 2024, residents of 10 villages held fresh gram sabhas rejecting purported consent resolutions from December 2023 that they alleged were “fraudulently obtained.” [NLS Blog; Down to Earth; GroundXero]

6.2 Shah Commission Findings: Industrial-Scale Illegality

The Justice M.B. Shah Commission of Enquiry revealed the scale of environmental governance failure:

  • 22.80 crore tonnes (228 million tonnes) of iron and manganese ore extracted illegally for almost a decade. [Down to Earth; Mines Ministry]
  • The scam in just two districts — Keonjhar and Sundargarh — was worth more than Rs 59,000 crore. [Business Standard, 2014]
  • From 54 hectares of pristine forests, mining companies extracted ore worth Rs 2,000 crore between 2003 and 2010 without any clearance or approval. [Down to Earth]
  • Of 192 mining leases examined, 176 were within dense forests and 94 were operating without environmental clearances. [Down to Earth]
  • At least 70 top companies including SAIL, Tata Steel, OMC, and Essel Steel were implicated. [Down to Earth; Scroll.in]
  • Average profit per tonne of iron ore increased from Rs 139.78 in 2001—02 to Rs 3,237.64 in 2010—11. [Shah Commission Report]
  • Illegal mining had been ongoing since 1994—95 in connivance with politicians, bureaucrats, and railway officials. South Eastern Railway detected freight charge evasion cases and issued demand notices to 14 companies for Rs 1,874 crore. [PIB; Down to Earth]

Environmental implication: 228 million tonnes of illegal extraction means ore removed without environmental assessment, without mitigation, without compensatory afforestation, and without rehabilitation. The ecological damage from illegal mining is by definition unmitigated.

The Supreme Court imposed a 100% penalty on companies found guilty and directed penalty funds toward tribal benefit in mining districts. [Scroll.in; Down to Earth, 2018]

6.3 Mining Lease Violations and CAG Findings

Odisha Mining Corporation (OMC):

  • CAG found OMC liable to pay Rs 1,328 crore in penalties for excess production: Kodingamali bauxite mine produced 27 lakh MT against the approved limit of 22.6 lakh MT; Sukrangi chromite mine extracted 1.67 lakh MT against a clearance of 1.30 lakh MT. [Kalinga TV; Odisha TV]
  • OMC had already paid Rs 4,364.15 crore in penalties between 2017 and 2022, including Rs 3,761.88 crore for violations of environmental and forest clearances and Rs 602.27 crore for mining beyond approved limits. [CAG]
  • Of 36 mining leases, 18 have remained non-operational for periods ranging from 6 to 35 years. [CAG]
  • Odisha lost Rs 4,162 crore to iron ore undervaluation. [Business Standard, 2026]

Mining beyond lease boundaries: The Shah Commission used satellite imagery to verify extraction beyond lease boundaries. The Mining Surveillance System (MSS), launched in 2016, uses satellite images to detect activity up to 500 metres beyond lease boundaries. Odisha generated 20 MSS triggers in one reporting period. [Shah Commission; Mines Ministry]

6.4 SPCB Capacity and Independence

The Odisha State Pollution Control Board operates 12 regional offices overseeing hundreds of mining operations, thermal power plants, and industrial units across the state. Structural constraints include:

  • Limited staff and budget relative to the scale of industrial activity
  • Enforcement actions (show-cause notices, closure orders) that are reactive rather than proactive, typically following public outcry, NGT orders, or environmental disasters
  • Structural conflict between the state government’s dependence on mining revenue and the SPCB’s environmental enforcement mandate
  • Documented cases of public hearing processes compromised under SPCB supervision (Vedanta Jharsuguda, Sijimali) [SPCB Odisha; various]

6.5 NGT as Corrective Mechanism

The National Green Tribunal has intervened repeatedly in Odisha:

  • POSCO: Suspended environmental clearance (March 2012)
  • Sukinda: Ordered Odisha government to provide clean drinking water (2024)
  • Vedanta Lanjigarh: Admitted plea on red mud breach, issued notices (2026)
  • BRPL Kalinganagar: Ordered re-investigation of wastewater discharge
  • JSW Paradip: Scrapped environmental clearance

The NGT acts as a corrective when state governance fails. But NGT orders are reactive, case-specific, and dependent on petitions being filed. They are not a systemic solution.

7. District Mineral Foundation (DMF)

7.1 Collection Data

Odisha leads India in DMF collection:

  • Cumulative collection till 30 June 2023: Rs 23,120 crore [PIB, Government of India]
    • Major minerals (non-coal): Rs 17,755.20 crore
    • Coal/lignite: Rs 5,237.58 crore
    • Minor minerals: Rs 127.21 crore
  • By October 2025, cumulative collection: Rs 34,052 crore from 11 DMF districts. [DMF Odisha; Business Standard]
  • Odisha’s DMF collection is the highest in India, far exceeding any other state.

The DMF was created under the MMDR Amendment Act 2015, with mining companies required to contribute 30% of royalty (for pre-2015 leases) or 10% (for post-2015 leases) to the DMF of the district where extraction occurs.

7.2 Utilisation Patterns

Actual allocation:

CategoryApproximate ShareNature
Roads and bridges>33%Infrastructure construction
Drinking water supply~25%Infrastructure construction
Healthcare and educationPresentPredominantly construction (buildings without staff)
Environmental preservation and pollution controlMinimalNegligible allocation
Direct livelihood supportSmallInadequate

[CSE India; Environics Trust; CSEP]

Utilisation rate: Only 49—55% of collected DMF funds have been utilised — nearly half remains unspent. [DMF Odisha portal]

CAG audit findings (2026):

  • Rs 983.32 crore diverted to 976 non-mining villages in Keonjhar and Sundargarh, while 584 mining-affected villages received zero benefits
  • 1,730 projects worth Rs 2,984.28 crore in Keonjhar implemented in Scheduled Areas without gram sabha approval
  • Rs 168.15 crore spent on school furniture in contravention of PMKKKY guidelines
  • 98 dentists and 83 specialists hired at rates significantly above government norms, resulting in excess payments of Rs 43.79 crore
  • Sundargarh DMF funds used to purchase 25 police patrol cars for Rourkela city — a non-mining-affected area [CAG Audit; Business Standard, 2026; Kalinga TV; Mongabay India, 2021]

7.3 The Paradox: Mining Revenue Funding Development, Not Environmental Remediation

The DMF was designed to benefit mining-affected people and areas. Environmental degradation is the primary mechanism through which mining affects people. Yet no publicly available data shows significant DMF allocation to:

  • Water decontamination in Sukinda or other chromite mining areas
  • Fly ash pond remediation in Jharsuguda or Angul
  • Forest restoration in deforested mining landscapes
  • Air quality improvement in critically polluted areas
  • Habitat restoration for elephant corridors

The money exists; the political will to direct it toward ecological repair does not. The DMF has become a parallel development fund — building roads, schools, and hospitals (often without adequate staff) — rather than addressing the specific environmental damage that justifies its existence.

Comparison with other mining states: While Odisha has the highest collection, the utilisation challenges are not unique. Jharkhand’s DMF also faces low utilisation rates and questions about spending priorities. However, Odisha’s scale of collection (Rs 34,000+ crore) makes the gap between accumulation and meaningful environmental remediation particularly stark.

8. Health Impacts

8.1 Silicosis and Occupational Respiratory Disease

Free silica/quartz is classified as a Group 1 carcinogen by IARC. In Odisha’s open-cast mines, workers are exposed to crystalline silica dust through drilling, blasting, loading, and transport operations.

Talcher coalfield studies: Assessments of suspended particulate matter, respirable dust (PM10), and free silica content in dust have been conducted across three mega coal mines (Bharatpur, Kaniha, and Lingaraj OCP) to determine exposure risk. [EcoInSEE; ResearchGate]

National context: A scoping review of silicosis prevalence in India found that the disease remains a major occupational health challenge, with prevalence as high as 37.3% among miners working over ten years in certain Indian mining regions. In Odisha, comprehensive epidemiological data specific to the mining workforce remains limited — the disease is underdiagnosed because many mine workers are contractual labourers from tribal communities without access to occupational health screening. [Journal of Occupational Medicine and Toxicology, 2024]

Contract labour vulnerability: Most workers in private iron ore and chromite mines in Keonjhar and Jajpur earn close to minimum wages (Rs 450—600/day) and lack formal employment status, social security, or occupational health monitoring. The Supreme Court ruled in 2024 (Mahanadi Coalfields vs Brajrajnagar Coal Mines Workers’ Union) that contract labour cannot be engaged for “permanent and perennial” jobs in coal mines, but enforcement remains limited. [MCL wage data; Supreme Court, 2024]

8.2 Respiratory Disease in Mining Corridors

Community health studies:

  • A study of 300 households found 90% of households in mining villages reported health problems, compared with 52% in non-mining villages 47 km away. [SAGE Journals, 2017]
  • Premature mortality in the Angul-Talcher-Jharsuguda corridor attributable to air pollution: PM2.5 (16—26%), PM10 (31—43%), NO2 (15—21%), SO2 (4—7%), O3 (3—6%). [MDPI Atmospheres, 2022]
  • Keonjhar residents suffer from respiratory illness linked to iron ore mining dust and ore transportation. Prolonged inhalation of dust causes lung damage and respiratory disease. [IOSR Journals; JETIR]

Mining-district malaria: In Keonjhar, iron ore mining has been linked to higher incidence of malaria in addition to respiratory illness. Mining-related deforestation and the creation of stagnant water bodies in abandoned pits facilitate mosquito breeding. [IOSR Journals]

Sukinda Valley (Jajpur): The most severe documented case — 84.75% of deaths in mining areas attributed to chromite-mine-related diseases. Hexavalent chromium (Cr VI) is a confirmed Group 1 carcinogen causing lung, nasal, and sinus cancers. Residents suffer gastrointestinal bleeding, tuberculosis, asthma, infertility, birth defects, and kidney ailments. [ScienceDirect, 2023; PMC, 2011]

Angul district: Industrial and municipal pollution coupled with high fluoride in drinking water have been linked to increasing rates of tuberculosis, cancer, and other ailments. [Springer; ResearchGate]

No systematic epidemiological study: Despite decades of documented contamination, no comprehensive state-commissioned epidemiological study has been conducted to quantify cancer incidence and mortality attributable to mining-related environmental contamination across Odisha’s mining districts. Individual academic studies exist for specific locations, but no district-level cancer registry data has been systematically correlated with mining activity or pollution exposure.

8.4 Tribal Health Disparities in Mining Districts

Tribal communities in mining districts face compounded health vulnerabilities:

  • Displacement from traditional food systems: Loss of forest-based nutrition (mahua, sal seeds, tubers, honey, medicinal plants) forces reliance on purchased food of lower nutritional quality
  • Water contamination exposure: Tribal hamlets located near mine sites and downstream of waste disposal areas face disproportionate exposure to contaminated water
  • Occupational exposure without screening: Tribal workers in mines and crusher units lack access to occupational health monitoring
  • Loss of traditional medicine: Destruction of forests eliminates access to medicinal plants that served as primary healthcare for generations
  • Infrastructure gaps: Mining-affected tribal areas often lack functional primary health centres despite DMF collections

The double burden: tribal communities bear the highest ecological cost of mining (displacement, pollution, forest loss) while having the least access to healthcare infrastructure to address the health consequences. This is not coincidence — it is structural. The same political-economic logic that extracts minerals from tribal land also under-invests in tribal health systems.

9. Remediation and Rehabilitation

9.1 Mine Closure Plans: Regulation vs Reality

Regulatory framework:

  • Mineral Concession Rules (amended 2003) mandate Progressive Mine Closure Plans (PMCP)
  • Final Mine Closure Plan (FMCP) required two years before proposed closure
  • Indian Bureau of Mines (IBM) published comprehensive FMCP appraisal manual (2022)
  • RECLAIM Framework (recent) provides structured guide for ecological transitions
  • Government made re-grassing of mined-out areas mandatory only in 2020, following a Supreme Court order — decades after mining began. [Mongabay India, 2020] [CSEP; IBM; Insights on India, 2025]

The gap:

  • Financial assurance for mine closure in India is notably lower than international benchmarks. In Western Australia, 25% of total restoration cost must be assured before mining begins; in Quebec, 70%. India’s requirements do not effectively deter defaulters. [CSEP; Responsible Mining Foundation]
  • No comprehensive registry of mine closure plan compliance in Odisha exists
  • Of OMC’s 36 mining leases, 18 have remained non-operational for 6 to 35 years — many without completed closure or remediation [CAG]

9.2 Environmental Remediation Costs: Unknown and Unquantified

No institution in India has attempted a comprehensive accounting of the cumulative ecological cost of mining in Odisha. The costs that would need to be estimated include:

  • Hexavalent chromium remediation in Sukinda (active treatment required for decades)
  • Acid mine drainage treatment at coal mines (essentially permanent)
  • Groundwater decontamination across Jajpur, Angul, Jharsuguda
  • Fly ash pond closure and remediation at Jharsuguda and Angul thermal plants
  • Red mud containment and soil remediation at Lanjigarh
  • Forest ecosystem restoration across 62,016+ hectares of diverted forest land
  • Elephant corridor reconstruction in Keonjhar, Angul, Dhenkanal
  • Watershed restoration on mined bauxite plateaus

The aggregate cost would likely run to tens of thousands of crores — possibly exceeding the DMF collection. But the cost has never been estimated because estimating it would create a political obligation to pay it.

9.3 Ecological Restoration Examples (Limited)

Successful ecological restoration of mining landscapes in Odisha is rare:

  • NTPC Talcher Kaniha: Recently claimed 100% ash utilisation — a positive development if verified, but exceptional rather than standard. [PSU Watch]
  • Revegetation studies: Long-term research shows leguminous plants can enhance mine spoil stability over 4—18 years, with soil organic carbon increasing 125—250%. But this represents the earliest stages of recovery, not ecosystem restoration. [Springer; Restoration Ecology]
  • No documented case of a mining landscape in Odisha being restored to ecological functionality comparable to its pre-mining state.

9.4 The Timescale Problem: Centuries of Damage vs Decades of Profit

Ecological recovery timescales:

ProcessTimescale
Open-cast mine excavation1—5 years to begin, ongoing
Mining lease duration20—50 years
CAMPA plantation (survival rate 7.5%)Planted in 1—3 years; most die
Soil nitrogen recovery to native forest levels~200 years
Acid mine drainage cessation50—100+ years (possibly indefinite)
Natural forest ecosystem restoration100—500+ years (if undisturbed)
Species recolonisation of restored habitatDecades to centuries
Chromite/heavy metal remediationNo known natural timescale

[Springer; Restoration Ecology; Nature Scientific Reports, 2025]

Forest cover in coal mining regions: A geospatial analysis found forest cover in central Indian coal mining areas declined from 35.56% in 1995 to 14.06% in 2024, with reclamation plantations insufficient to reverse the trend. [ScienceDirect, 2025]

The fundamental asymmetry: mining extracts value over 20—50 year lease periods, while the ecological damage persists for centuries. The profits are captured by the current generation of shareholders, operators, and the state treasury. The costs — contaminated water, destroyed forests, fragmented wildlife habitat, poisoned soil — are borne by future generations who had no voice in the decision to extract. This is intergenerational ecological debt with no mechanism for repayment.

9.5 The Climate Dimension

Carbon release from deforestation: The 62,016+ hectares of forest diverted for mining stored substantial carbon. Tropical forests of the type destroyed in Odisha store approximately 50—150 tonnes of carbon per hectare in above-ground biomass and 40—80 tonnes per hectare in soil. Their destruction releases stored carbon and eliminates future sequestration capacity.

Coal as direct emissions: Odisha’s coal mines release methane during extraction. The Talcher and Ib Valley coalfields are significant methane emission sources. The 12—15 GW of coal-fired thermal power capacity in the corridor is one of India’s largest concentrated CO2 sources.

The paradox: Odisha’s Eastern Ghats forests are among the state’s most valuable climate assets. Mining destroys these assets to extract minerals whose processing is itself carbon-intensive. The state destroys its climate resilience infrastructure to produce goods that accelerate climate change — while being among India’s most cyclone-vulnerable states.

Confidence note (Principle 7): The probability that Odisha will undertake comprehensive ecological restoration of mining landscapes within the next decade is estimated at below 15%. Structural incentives favour continued extraction with minimal remediation.

10. Niyamgiri as Counter-Example: The Environmental Cost That Was Not Incurred

10.1 The Supreme Court Judgment

On April 18, 2013, the Supreme Court of India delivered a landmark judgment in Orissa Mining Corporation Ltd vs Ministry of Environment & Forest. Rather than ruling directly on whether Vedanta could mine bauxite on the Niyamgiri Hills, the Court directed that the gram sabhas (village assemblies) of affected communities should determine whether mining would violate their religious and cultural rights. The Court read Section 4(d) of PESA (1996) and Section 6 of the Forest Rights Act (2006) to recognise that the Dongria Kondh — a Particularly Vulnerable Tribal Group (PVTG) numbering approximately 8,000 people — had the right to decide the fate of their sacred mountain. [Supreme Court Judgment; Amnesty International]

10.2 The Gram Sabha Referendum

Between July and August 2013, amidst heavy police presence and persistent threats from Vedanta, 12 gram sabhas voted unanimously against the mining project. All 12 delivered a resounding “No.” This was India’s first environmental referendum — the first time affected communities were given legal authority to reject a mining project through democratic vote. [Down to Earth, 2023; Amnesty International]

In January 2014, the Ministry of Environment and Forests — which had earlier aided Vedanta’s efforts — formally rejected the project.

10.3 The Environmental Cost That Was Avoided

The Niyamgiri Hills (elevation 1,516 m) contain an estimated 72 million tonnes of bauxite. Had mining proceeded, the ecological consequences would have included:

Watershed destruction: The Niyamgiri Hills support over 300 perennial streams feeding the Vamsadhara and Nagavali river systems. The bauxite cap acts as a natural water tower — porous laterite absorbs monsoon rainfall and releases it slowly through the year. Mining would have removed this cap, eliminating the streams and their downstream benefits to agriculture, aquatic ecosystems, and human habitation across Rayagada and Kalahandi districts.

Biodiversity loss: The Niyamgiri forests are home to 73 types of trees, 21 varieties of grasses, 20 varieties of mammals, and numerous reptiles, birds, and amphibians. The hills harbour medicinal plants and NTFPs that sustain the Dongria Kondh economy.

Sacred landscape destruction: The Niyamgiri summit is the abode of Niyam Raja — the supreme deity of the Dongria Kondh. The mountain is not merely a resource but the centre of a living cosmological system. Its destruction would have been the destruction of an entire cultural-spiritual framework.

Downstream contamination: As the September 2024 red mud breach at the nearby Lanjigarh refinery demonstrated, bauxite processing generates toxic waste that contaminates rivers and farmland. Had Niyamgiri been mined, the processing would have intensified at Lanjigarh, amplifying the contamination that has already occurred.

10.4 Current Status

The mining project remains banned. In February 2016, the Odisha Mining Corporation filed an application challenging the gram sabha resolutions, alleging technical errors. The Supreme Court upheld its earlier judgment and rejected OMC’s petition. [Business Standard, 2016]

The Niyamgiri Hills today remain forested, with their watershed intact, their biodiversity preserved, and the Dongria Kondh community continuing to live on and from their ancestral mountain. The 300+ streams still flow. The bauxite cap still stores and releases water. The forest canopy still shelters wildlife and sequesters carbon. This is the counter-factual against which the ecological cost of every other mining project in Odisha should be measured: what the landscape would look like if extraction had not occurred.

10.5 The Irony: Lanjigarh Refinery Continues

The Vedanta alumina refinery at Lanjigarh — the very facility for which Niyamgiri bauxite was to be mined — continues to operate using bauxite sourced from OMC and imports. It has expanded to 6 MTPA capacity. And it has generated severe environmental damage: the September 2024 red mud breach released 400,000 cubic metres of toxic wastewater across 50+ villages. The gram sabha victory prevented one form of destruction (mountaintop removal) while the refinery delivers another (toxic waste contamination).

10.6 Sijimali: The Next Niyamgiri?

Vedanta’s Sijimali bauxite mining project — 311 million tonnes of reserves, 9 MTPA planned extraction over 31 years, 700+ hectares of forest diversion sought in Rayagada and Kalahandi — faces similar community resistance. The Union Environment Ministry deferred its decision on forest clearance in 2024 due to concerns over community consent and ecological impact. Residents of 10 villages held fresh gram sabhas in August-September 2024 rejecting alleged fraudulent consent resolutions. The project would impact 73 tree types, 21 grass varieties, 20 mammal species, and 200+ perennial streams emerging from Sijimali. Stage 1 forest clearance was reportedly granted on December 31, 2025, but environmental clearance and Stage 2 clearance remain pending. [Down to Earth; OdishaPlus; GroundXero; AlCircle]

Whether Sijimali becomes another Niyamgiri (community victory) or another Kodingamali (mining proceeds despite resistance) will test whether the institutional precedent of gram sabha authority is durable or was a one-time exception.
