Top court seeks names for expert committee to define the Aravallis

Supreme Court Seeks Names for Expert Committee to Define the Aravallis

UPSC Prelims + Mains Study Note

1. At a Glance

• The Aravalli Hills — among the world's oldest fold mountains — span Delhi, Haryana, Rajasthan, and Gujarat; they serve as a critical ecological barrier against desertification from the Thar Desert. [S1]
• The Supreme Court of India is adjudicating a landmark case (In Re: Issues Relating to Definition of Aravalli Hills and Ranges) that directly determines which land is protected from mining. [S3]
• A definitional dispute — whether a landform qualifies as "Aravalli" — has enormous stakes: it governs the legality of mining leases, forest protection, and urban expansion in the NCR region. [S3]
• UPSC relevance: touches Environment (GS-III), Polity/Judiciary (GS-II), Geography (GS-I), and Governance simultaneously. [S1][S2]

2. Why in the News

• 20 November 2025: Supreme Court accepted a uniform definition of Aravalli hills/ranges (based on a MoEFCC committee recommendation) and banned fresh mining leases across the four Aravalli states pending experts' reports. [S2][S4]
• 28–29 December 2025: SC took suo motu cognisance of the outcry over this new definition; stayed its own November 20 order and halted all mining activities after concerns arose that the definition was being misconstrued. [S4][S5]
• 21 January 2026: SC announced it would constitute an expert committee of domain experts for an exhaustive and holistic examination of mining and related issues in the Aravallis. [S6]
• 27 February 2026 (triggering news item): A Bench of CJI Surya Kant, Justice Joymalya Bagchi, and Justice Vipul M. Pancholi asked the Environment Ministry and other stakeholders to suggest names of domain experts for this panel; extended the earlier stay order. [S7]

3. Background & Evolution

4. Core Static Facts

Geography - Location: Northwestern India; runs ~800 km from Delhi (Raisina Hill) through Haryana → Rajasthan → Gujarat (Palanpur) - States covered: Delhi, Haryana, Rajasthan, Gujarat [S1] - Age: Among the world's oldest fold mountains (Precambrian, ~3,500 million years old) [S1] - Highest peak: Guru Shikhar (Mt. Abu, Rajasthan) — ~1,722 m

Ecological Role - Acts as a windbreak preventing eastward advance of Thar Desert (desertification barrier) - Recharges the Aravalli aquifer system; crucial for groundwater in Delhi-NCR and Rajasthan - Biodiversity: Leopards, Indian wolves, striped hyenas, migratory birds [S1]

Legal/Definitional Framework (MoEFCC Committee's Proposal — Nov 2025) - Aravalli Hill: Any landform in designated Aravalli districts with elevation ≥ 100 metres above local relief [S2][S4] - Aravalli Range: Two or more such hills within 500 metres of each other [S2]

Institutional Actors - Ministry: Ministry of Environment, Forest and Climate Change (MoEFCC) — nodal ministry [S2] - Apex court: Supreme Court of India (suo motu cognisance) [S5] - Earlier oversight body: Central Empowered Committee (CEC), constituted under SC orders - Mining law: Mines and Minerals (Development and Regulation) Act, 1957 (MMDR Act) — Seventh Schedule lists strategic minerals [S2]

Mining Restrictions (as per SC order) - No fresh mining leases in core/inviolate areas - Exception: Critical, strategic, and atomic minerals + minerals in Seventh Schedule of MMDR Act, 1957 [S2] - All mining activities stayed as of December 29, 2025 [S5]

5. Multi-Dimensional Analysis

Environmental

• Aravallis are the only ecological barrier between the Thar Desert and the Indo-Gangetic Plain; their degradation accelerates desertification and dust storms in Delhi-NCR. [S1]
• Illegal mining has caused topographical destruction — removal of hilltops makes them ineligible under any elevation-based definition, creating a perverse incentive. [S3]
• The SC noted risk of "irreversible damage" to the ecology if mining continues without a holistic plan. [S3]
• The range supports watershed functions for rivers Banas, Luni, Sabarmati, Rupen — disruption affects water security across four states. [S1]

Legal / Constitutional

• The case is being heard suo motu by the Supreme Court under Article 32 read with the public trust doctrine and the precautionary principle (both part of Indian environmental jurisprudence). [S3]
• Earlier definitional order of 20 November 2025 was kept in abeyance — rare instance of SC staying its own order, reflecting judicial acknowledgement of definitional complexity. [S5]
• Mining governance: MMDR Act, 1957 (Central) + State minor mineral rules — federal tension over jurisdiction. [S2]
• Enabling forest law: Forest (Conservation) Act, 1980 (now Van (Sanrakshan Evam Samvardhan) Adhiniyam, 2023 after amendment). [S1]

Administrative / Governance

• The definitional dispute is not merely academic: mining leases in Rajasthan and Haryana were granted on lands later claimed to be Aravalli — billions in economic interests at stake. [S3]
• Creating an expert committee (geologists, ecologists, remote-sensing specialists) reflects SC's move away from MoEFCC-only determination to multi-disciplinary independent assessment. [S7]
• State governments (especially Haryana and Rajasthan) have divergent interests — mining royalty revenues vs. forest protection mandates. [S3]

Economic

• Mining (marble, quartzite, sandstone, limestone) is a major revenue source for Rajasthan; blanket stay disrupts livelihoods of quarry workers and stone-cutting MSMEs. [S3]
• The SC's exception for strategic/atomic minerals reflects the critical minerals strategy under India's emerging battery/clean-energy ecosystem. [S2]
• Real estate in Faridabad, Gurugram corridor is directly impacted — constructions on Aravalli land face demolition risk if definition is broadly drawn. [S3]

Geopolitical / Strategic

• Broader context: India's Critical Minerals Mission (Budget 2024-25) seeks domestic sourcing; any mining ban must carve out strategic mineral extraction — SC's exemption framework aligns with this. [S2]

Scientific / Technological

• MoEFCC's committee recommended satellite-based remote sensing and GIS mapping to demarcate Aravalli boundaries objectively. [S1]
• Expert committee expected to include geomorphologists and remote-sensing experts to provide a scientifically defensible boundary. [S7]

6. Recent Developments (Last 12–18 Months)

• 22 December 2025: Union Minister Bhupender Yadav (MoEFCC) stated no new mining leases would be permitted in ecologically sensitive areas. [S8]
• 28 December 2025: SC takes suo motu cognisance of protests/outcry over its November 20 Aravalli definition order. [S5]
• 29 December 2025: SC stays November 20 order; orders formation of a new expert committee on Aravalli range definition; all mining stalled. [S5]
• 21 January 2026: SC says it will constitute expert committee for holistic examination of Aravalli mining issues. [S6]
• 27 February 2026: Bench of CJI Surya Kant + Justices Bagchi & Pancholi asks MoEFCC and stakeholders to suggest domain expert names for the panel; extends stay order. [S7]

10. Common Errors / Trap Areas

1. "MoEFCC defined the Aravallis" — Wrong. MoEFCC's committee only recommended the definition; the Supreme Court accepted it on 20 Nov 2025, then stayed it on 29 Dec 2025. The definition is not yet final.
2. Confusing the stay dates: The SC order banning fresh leases was 20 November 2025; the stay of that order was 29 December 2025 — do not conflate.
3. "All mining banned permanently" — Wrong. The SC stay is interim; critical/strategic/atomic mineral extraction is exempted even within core Aravalli areas.
4. Highest peak confusion: Guru Shikhar is in Rajasthan (Mt. Abu), not Haryana — aspirants sometimes place it in Haryana because that is where Aravalli controversies are most prominent.
5. Wrong ministry: Some aspirants cite Ministry of Mines as the nodal body — it is MoEFCC for ecological protection; Ministry of Mines handles MMDR Act but MoEFCC leads the SC committee.
6. Confusing CEC with the new expert committee: The Central Empowered Committee (CEC) is an existing SC-appointed body for forest/mining compliance; the new expert panel is a separate domain-expert committee being constituted specifically to define Aravalli boundaries.
