Gadchiroli Mining & Tadoba-Indravati Tiger Corridor: Why Wildlife Clearance Matters

• The legal trigger: Under India's wildlife law, any project that diverts land lying within a notified tiger corridor cannot be cleared by the State alone — it requires the approval of the National Board for Wildlife (NBWL) and the advice of the National Tiger Conservation Authority (NTCA). By declaring that the project does not fall in a tiger corridor, the State effectively removed the project from this stricter central scrutiny.

• The factual dispute: The Tadoba–Indravati corridor is mapped in the NTCA-approved Tiger Conservation Plan using specific "forest compartments" (administrative survey blocks into which a forest is divided for management). The contention is that most of the very compartments handed over to the project are the same compartments that the official corridor map lists as part of the tiger corridor. If true, the exemption rests on an incorrect factual premise.

• Why it matters beyond one project: Gadchiroli holds a large share of Maharashtra's forest cover and sits on the dispersal route between two tiger reserves. The region forms part of an ecological corridor connecting the Tadoba and Indravati tiger reserves — an essential habitat for tigers, leopards and elephants. (Counterview) A single exemption can become a template for many future projects in the same landscape.

• Definition: A tiger corridor is a stretch of habitat — often degraded or human-used forest, not a fully protected park — that physically links one tiger reserve or protected area to another. It is not a "reserve" itself but the connective tissue between reserves.

• The science of connectivity: Tigers are territorial and far-ranging. A single reserve can hold only a limited number of breeding tigers (its "carrying capacity"). When a reserve fills up, young "sub-adult" tigers must disperse to find new territory. Corridors allow this movement, enabling tigers from different reserves to mix. This exchange of individuals keeps the gene pool diverse (preventing inbreeding) and allows isolated populations to function as one larger, healthier "metapopulation." Corridor conservation links isolated reserves, mitigating inbreeding risks documented in small populations below 50 individuals. (Grokipedia)

• Consequence of breaking a corridor: When a corridor is fragmented by mining, roads or settlements, tiger populations become isolated islands. Dispersing tigers blocked from safe routes spill into farms and villages, sharply raising human–wildlife conflict.

• Tadoba–Andhari Tiger Reserve (TATR): Located in Chandrapur district, Maharashtra, it is the State's oldest and largest tiger reserve. Tadoba National Park was created in 1955, the Andhari Wildlife Sanctuary was formed in 1986, and the two were merged in 1995 to establish the present Tadoba–Andhari Tiger Reserve. (Tadoba National Park) It is one of India's densest tiger habitats, holding roughly 90–100 tigers in recent estimates.

• Indravati Tiger Reserve: Located across the border in Chhattisgarh (named after the Indravati river), it is a key reserve in central India's tiger landscape.

• The corridor between them: The forests of Gadchiroli physically bridge Tadoba in Maharashtra with Indravati in Chhattisgarh. This is precisely why Gadchiroli's forests are treated as a corridor and not merely as ordinary forest land — they carry the movement of tigers between two States.

• Project Tiger (1973): Project Tiger was launched on 1 April 1973 from Jim Corbett National Park, when India's tiger numbers had fallen to around 2,000 after rampant hunting. (pressreader) It began with nine tiger reserves spanning over 18,000 sq km and has since expanded to more than 50 reserves covering around 75,000 sq km, roughly 2.3% of India's land area; India now harbours about 75% of the world's wild tigers. (Press Information Bureau)

• The 2006 statutory backbone: For three decades Project Tiger ran as a centrally sponsored scheme without firm legal backing. After the Sariska crisis (where tigers vanished due to poaching), the Wildlife (Protection) Act, 1972 was amended in 2006 to create two statutory pillars:

• The National Tiger Conservation Authority (NTCA)

A formal system of core (critical tiger habitat) and buffer zones for each reserve.

• National Tiger Conservation Authority (NTCA): The NTCA is a statutory body under the MoEFCC, established in 2006 under the Wildlife (Protection) Act, 1972. (Laex) It is headed by the Union Environment Minister as Chairperson, with the Minister of State for Environment as Vice-Chairperson, and works closely with State Forest Departments, tiger reserves and the Wildlife Institute of India (WII). (InsightsIAS) Its functions include approving the Tiger Conservation Plans of States, conducting the All-India Tiger Estimation, and regulating land use in reserves and corridors.

• Section 38-O — corridor protection: This is the heart of the present controversy. Under Section 38-O(1)(g) of the Wildlife (Protection) Act, 1972, areas linking one tiger reserve or protected area with another must not be diverted for ecologically unsustainable uses, except in public interest and with the approval of the National Board for Wildlife and on the advice of the NTCA. (National Tiger Conservation Authority) This is exactly the safeguard that a "no corridor" declaration bypasses.

• Section 38-V — Tiger Conservation Plan (TCP): Section 38-V(3) requires the State government to prepare a Tiger Conservation Plan to ensure protection of tiger reserves and ecologically compatible land use, including in the areas linking reserves. (iPleaders) The TCP is the document on which the corridor compartments in this case are officially mapped.

• Section 38-O power to disallow projects: The NTCA is empowered to evaluate sustainable ecology and disallow ecologically unsustainable land use such as mining, industry and other projects within tiger reserves. (Simplified UPSC)

• The "32 corridors" document: The NTCA, with the Wildlife Institute of India, identified 32 major tiger corridors in the country in a document titled "Connecting Tiger Populations for Long-term Conservation", operationalised through the Tiger Conservation Plan under Section 38-V. (National Tiger Conservation Authority)

• National Board for Wildlife (NBWL): The NBWL is a statutory authority under Section 5-A of the Act, chaired by the Prime Minister, that advises Central and State governments on wildlife conservation; its Standing Committee clears projects in and around protected areas. (iPleaders)

• This is a frequent point of confusion for aspirants. A forest-based industrial project typically passes through three distinct clearances under three different laws:

• Forest Clearance: Required when forest land is diverted for non-forest use, under the Forest (Conservation) Act, 1980 (now renamed the Van (Sanrakshan Evam Samvardhan) Adhiniyam, 1980, after the 2023 amendment). It is recommended by the Forest Advisory Committee (FAC) of the MoEFCC and granted in "in-principle" (Stage-I) and final (Stage-II) stages.

• Wildlife Clearance: Required when the land falls inside or near a protected area, an eco-sensitive zone, or a tiger corridor. It is granted by the Standing Committee of the NBWL, with NTCA advice for tiger corridors. This is the clearance the Gadchiroli project was exempted from.

• Environmental Clearance (EC): Required under the Environment (Protection) Act, 1986 and the EIA Notification, 2006. It is appraised by an Expert Appraisal Committee (EAC) and follows an Environmental Impact Assessment and, usually, a public hearing.

• Why the distinction is decisive here: A project can secure forest and environmental clearance yet still be blocked at the wildlife stage if it sits in a corridor. Removing the corridor tag is therefore the single most effective way to fast-track such a project.

• Forest Rights Act (FRA), 2006: The FRA recognises the customary rights of Scheduled Tribes and Other Traditional Forest Dwellers and empowers the Gram Sabha in forest governance. (UnderStand UPSC) Critically, for diversion of forest land, a 2009 MoEFCC process requires evidence that forest rights have been recognised and that affected Gram Sabhas have given their free, prior and informed consent. The FRA also places a duty on rights-holders and Gram Sabhas to protect wildlife, forests and biodiversity and to stop activities that adversely affect wild animals. (India Code)

• PESA, 1996: The Panchayats (Extension to the Scheduled Areas) Act extends self-governance to Fifth Schedule tribal areas and makes Gram Sabha consultation central to decisions on land and resources. Gadchiroli has 1,567 villages, of which 1,311 fall under PESA. (Jhatkaa)

• The concern raised by activists: Critics allege that several environmental approvals in the region have been granted without the Gram Sabha consultation or consent required under both PESA, 1996 and the Forest Rights Act, 2006. (Jhatkaa) This converts a purely environmental dispute into a governance and tribal-rights question, linking it to GS Paper II as well.

• The Surjagarh operation: Lloyds Metals & Energy holds an iron-ore mining lease over about 348 hectares at Surjagarh, Gadchiroli, first executed in 2007 and later extended up to 2057. (business-standard)

• Earlier 2025 clearances: The Centre granted in-principle forest clearance for an iron-ore beneficiation plant requiring diversion of 937 hectares of forest land and felling of about 1.23 lakh trees, to be used in three phases — 300 hectares, 200 hectares, and a final 237 hectares subject to compliance review. (Swarajyamag) Separately, the Environment Ministry's expert panel recommended expanding the Surjagarh mine from 10 million tonnes per annum to 26 MTPA. (Swarajyamag)

• The development rationale offered: Authorities have argued that mining brings revenue, employment and security-force access to an LWE-affected district, and that formal mining has reduced illegal felling and smuggling along the Indravati river. This is the "development" side of the debate.

• There is a parallel national controversy directly relevant to this case. The NTCA has moved to limit the definition of tiger corridors largely to the 32 "least-cost pathways" from its 2014 report, excluding several Wildlife Institute of India studies and tiger-estimation data. (InsightsIAS) Conservationists warn that narrowing the corridor definition could ease clearances for mining and infrastructure projects, while industry views the earlier broad definition as a cause of project delays. (InsightsIAS) The Gadchiroli case sits squarely within this tension: how narrowly or broadly a corridor is defined determines whether wildlife clearance is triggered at all. (Present multiple views: conservation security versus regional development needs — without taking sides.)

• India's tigers: The 2022 All-India Tiger Estimation placed the population at an average of about 3,682 tigers (range roughly 3,167–3,925). (Tadobanationalparkonline)

• Tadoba's count: Tadoba held about 97 tigers in the 2022 estimation, among the highest in the country. (Press Information Bureau)

• Project Tiger scale: From 9 reserves over ~18,000 sq km in 1973 to more than 50 reserves over ~75,000 sq km today.

• Conflict data: Maharashtra reported 111 human deaths from tiger attacks in 2022–23 and 59 in 2023–24, (tribuneindia) underscoring the human-wildlife conflict dimension.
