This case study shows why courts must decide whether terrain can be treated as ecologically dispensable before legal definitions necessarily expose it to foreseeable harm.
The Supreme Court of India has described the Aravalli Hills and Ranges (the Aravallis) as the indispensable ecological and socio-economic backbone of the region, functioning as the primary geographical barrier separating the arid north-western desert from the fertile northern plains. The Court has further characterised the Aravallis as the “green lungs” of north-western India, which have for centuries sustained diverse ecosystems and underpinned the livelihoods of numerous communities.[1]
Owing to their ancient geological formation, the Aravalli Hills and Ranges host some of the nation’s most significant mineral deposits. In this context, the Court has noted longstanding allegations of escalating anthropogenic pressures—including unchecked urbanization, systematic deforestation, and intensive resource extraction—exerting strain upon what it describes as an inherently fragile ecosystem.[1]
In this context, the Supreme Court of India has been actively seized of issues concerning mining operations within the Aravallis since 1991, beginning with proceedings to enforce statutory protections over forest, wildlife, and ecologically sensitive areas. In that phase of the jurisprudence, the Court consistently held that where terrain was already legally protected, it could not be subjected to mining or other degrading activity, and that failures of enforcement could not be justified by administrative uncertainty.[2, 3, 4, 5, 6]
Related environmental jurisprudence also addresses the precautionary principle, ecological risk, and expert-assisted adjudication in upstream legal determinations.[7, 8, 9]
Committee records before the Court, including dissenting submissions, reflect long-running contestation over ecological protection in the Aravalli context.[10]
In its judgment dated 20 November 2025 in the present matter, the Court framed its concern as “the definition of Aravali Hills and Ranges and the need for the proper conservation of the same in the States of Delhi, Haryana, Gujarat and Rajasthan.”[11]
The Court accepted the findings of a Committee constituted for this purpose, including the definition of the Aravalli Hills and Ranges. As the Court subsequently recorded, “This definition served as the primary foundation for the Committee’s recommendation that ‘no new mining leases’ be granted within the newly demarcated ‘Aravalli Hills and Ranges’.”[1]
However, in its subsequent order of 29 December 2025, the Court expressly noted that definitional choices, if not carefully examined, may give rise to ambiguity and unintended consequences. The Court therefore observed that “there is a dire need to further probe and clarify to prevent any regulatory gaps that might undermine the ecological integrity of the Aravalli region.”[1]
In the same order, the Court further observed that “prior to the implementation of the Committee’s Report, or the execution of the directions contained in paragraph 50 of this Court’s judgment dated 20.11.2025, a fair, impartial, independent expert opinion must be obtained and considered, after associating all requisite stakeholders.” The Court further emphasized that such a step is “essential to resolve critical ambiguities and to provide definitive guidance.”[1]
This simulation is designed to assist that upstream exercise of clarification. It does not assess mining, projects, or specific sites. It is not an environmental impact assessment, and it does not depict a real map. Instead, it visualizes the legal and structural consequences that follow from adopting alternative definitional frameworks—the very issues the Court has identified as requiring clarification before downstream actions are taken.[1, 12] By showing how different definitions include or exclude terrain, the simulation makes visible how definitional choices can expose terrain to downstream processes of disturbance or disintegration. It does not determine whether such exposure is constitutionally permissible. Rather, it clarifies what is placed at risk of harm by definition, thereby underscoring the need to address the constitutional question of ecological dispensability of the terrain under Articles 21 and 48A, read with the precautionary principle, intergenerational equity, and the doctrine of public trust.[13, 14, 15]
Nothing on this terrain changes as you scroll.
The hills do not move.
The valleys do not shift.
Only the definition changes — and with it, what is treated as protected and what is excluded.
This is not a map of any real place.
It is a visual aid for noticing something subtle but powerful:
how definitional choices alone can determine what becomes legally exposed before any activity begins.
Please use a desktop device to see how a map of synthetic terrain visually displays the impact of the questions below.
Downstream processes are the ordinary mechanisms through which legally exposed terrain may be acted upon: land-use change, extraction, fragmentation, hydrological alteration, infrastructure insertion, and cumulative disturbance. These processes do not begin with projects or permissions; they begin when exposure is created by definition.
Whether such processes may be permitted turns on their effect on ecological integrity.
Ecological integrity is the emergent result of the continuity of relationships among parts of an ecosystem that allow it to function as a whole. When those relationships are broken, no amount of replacing, upgrading, or compensating individual parts can restore the system’s function, identity, or continuity.
Ecological dispensability is the ability to expose a part of an ecosystem to harm without losing the function, identity, and continuity it gives to the whole.
That determination must precede exposure being treated as permissible and cannot be deferred to downstream assessment.[13, 14, 15]
Across legal systems, a common distinction exists.
Some decisions are about managing impact — how to reduce harm, how to mitigate damage, how to regulate use.
Other decisions come earlier. They concern whether certain terrain or ecological capability should be exposed to harm at all.
That earlier question is not scientific in nature. Science can explain what ecological functions exist and how harm occurs. It cannot decide whether those functions may be sacrificed.
Nor is it an administrative or executive question. Regulation, planning, and impact assessment operate only after exposure is treated as permissible in principle. They manage consequences; they do not decide foundational limits.
In constitutional systems, that foundational limit is set by instruments that protect the conditions of life, continuity, and obligation across generations.
International recognition of the right to a clean, healthy, and sustainable environment affirms the legal importance of protecting ecological conditions essential to life and well-being.[21]
In India, this role is performed by the Constitution itself — through the right to life under Article 21, the duty to protect the environment under Article 48A, and the principles that flow from them, including precaution, public trust, and intergenerational equity.[13, 14, 15]
These principles point to a simple but unavoidable requirement: before terrain is exposed to degradation by definition or exclusion, it must first be determined whether it is ecologically dispensable.
Once exposure is permitted, assessment and regulation can follow. But they cannot decide what should never have been exposed in the first place.
That unanswered question — of ecological dispensability — belongs to this earlier, constitutional category.
