Impact on biodiversity claims

Introduction

The impact on biodiversity claims concerns the legal consequences of activities that damage ecosystems, threaten species, destroy habitats or reduce genetic diversity. Such claims may arise against governments, corporations, developers, agricultural operators, biotechnology companies and other entities whose activities contribute to environmental degradation. Biodiversity litigation seeks to prevent ecological harm, obtain restoration or compensation where legally available, and enforce statutory obligations relating to environmental protection.

Biodiversity is essential for ecological stability, food security, public health and sustainable economic development. However, habitat destruction, pollution, climate change, invasive species and unsustainable resource extraction continue to threaten biological diversity. Legal claims concerning these impacts may involve constitutional environmental rights, statutory conservation duties, environmental impact assessment, public trust principles and civil liability.

In India, biodiversity protection is supported by constitutional provisions, environmental legislation and judicial decisions. The legal basis and available remedies depend on the particular harm, the applicable statute, the claimant's standing and the evidence connecting the alleged conduct to ecological damage.

Constitutional foundations of biodiversity claims

The Constitution of India provides an important foundation for environmental protection. Article 21, which protects life and personal liberty, has been interpreted by the Supreme Court to encompass aspects of the right to a healthy environment. Article 48A directs the state to protect and improve the environment and safeguard forests and wildlife, while Article 51A(g) places a fundamental duty on citizens to protect and improve the natural environment and show compassion for living creatures.

These provisions support environmental interpretation and governance, although Articles 48A and 51A(g) do not independently create an automatic right to compensation in every biodiversity dispute.

In Subhash Kumar v State of Bihar (1991) 1 SCC 598, the Supreme Court recognised that Article 21 includes the right to enjoy pollution-free water and air. The Court also cautioned that constitutional litigation must not be misused for personal interests unrelated to genuine public injury. The judgment supports environmental claims where pollution threatens life and health, but it does not establish liability for every loss of biodiversity.

Statutory framework for biodiversity protection

Several Indian laws provide mechanisms for preventing or addressing biodiversity loss.

The Biological Diversity Act, 2002, as amended by the Biological Diversity (Amendment) Act, 2023, regulates matters including access to biological resources, associated traditional knowledge and benefit-sharing, subject to the applicable provisions and rules. It also establishes institutional arrangements involving the National Biodiversity Authority, State Biodiversity Boards and Biodiversity Management Committees.

The Environment (Protection) Act, 1986 provides a broad framework for environmental protection and regulatory action. The Wild Life (Protection) Act, 1972 addresses wildlife protection and protected areas. The Forest (Conservation) Act, 1980, now titled the Van (Sanrakshan Evam Samvardhan) Adhiniyam, 1980, regulates specified uses of forest land under the applicable statutory framework.

The National Green Tribunal Act, 2010 establishes a specialised forum for specified environmental disputes, including claims for relief and compensation within its statutory jurisdiction. Section 15 permits certain forms of relief, compensation and restitution, including restoration of damaged property and the environment, subject to the Act's conditions and limitations.

Public trust doctrine and ecosystem protection

The public trust doctrine holds that the state has responsibilities concerning certain natural resources that must be protected for public benefit. It can provide a basis for challenging government decisions that unlawfully permit the destruction or degradation of ecologically important resources.

In M.C. Mehta v Kamal Nath (1997) 1 SCC 388, the Supreme Court of India applied the public trust doctrine in relation to interference with the River Beas and the surrounding environment. The judgment established an important principle that the state cannot treat protected natural resources simply as assets available for private exploitation.

This case is highly relevant to biodiversity claims involving wetlands, rivers, forests and other ecologically important areas. Where public authorities fail to protect resources entrusted to them, affected parties may seek judicial intervention, subject to standing, jurisdiction and the facts of the case.

The doctrine does not mean that every alteration of nature is unlawful. Courts must consider the applicable legislation, ecological significance, public interest and the legality of the disputed activity.

Environmental impact assessment and development projects

Infrastructure, mining, industrial facilities and large-scale land development can damage habitats and fragment ecosystems. Environmental impact assessment (EIA) procedures are intended to identify significant environmental risks before certain projects receive approval.

In India, the Environment (Protection) Act, 1986 and the applicable Environmental Impact Assessment Notification, 2006 establish important requirements for prior environmental clearance for specified categories of projects. The precise obligations depend on the project's classification, location and applicable exemptions or amendments.

In Hanuman Laxman Aroskar v Union of India (2019) 15 SCC 401, the Supreme Court considered environmental clearance for the proposed Mopa airport in Goa. The Court emphasised the importance of a lawful, informed and environmentally responsible assessment process and examined deficiencies in the decision-making record.

The judgment is relevant to biodiversity claims because environmental approvals must be supported by proper consideration of material environmental impacts. A claimant may challenge an approval where the applicable assessment requirements have not been met or relevant ecological information has been inadequately considered.

Precautionary principle and scientific uncertainty

Biodiversity damage may be difficult to reverse, and scientific evidence may not always establish the full consequences of a proposed activity before it begins. The precautionary principle supports preventive action where there is a credible threat of serious or irreversible environmental harm, even if some scientific uncertainty remains.

In Vellore Citizens' Welfare Forum v Union of India (1996) 5 SCC 647, the Supreme Court recognised the precautionary principle and the polluter-pays principle as important components of Indian environmental law.

The decision supports preventive regulation and environmental remediation where legally justified. In biodiversity disputes, authorities may need to consider habitat fragmentation, groundwater depletion, toxic pollution or damage to threatened species before authorising potentially harmful activities.

The precautionary principle does not automatically establish liability merely because an activity carries some environmental risk. Decisions must still be grounded in the relevant law and supported by appropriate evidence.

Polluter-pays principle and ecological compensation

The polluter-pays principle requires those responsible for environmental pollution to bear appropriate costs of preventing, controlling and remedying the damage, in accordance with applicable law. In biodiversity cases, remedies may include habitat restoration, pollution control, compensatory measures and monetary compensation.

In Indian Council for Enviro-Legal Action v Union of India (1996) 3 SCC 212, the Supreme Court addressed severe environmental pollution caused by chemical industries in Rajasthan. The Court affirmed the importance of holding polluting industries financially responsible for remediation.

The case provides a significant foundation for claims involving ecological degradation caused by industrial operations. However, the amount and form of relief depend on the evidence, the statutory basis of the claim and the court or tribunal's jurisdiction.

Biodiversity restoration may require more than monetary payment. Depending on the damage, effective remedies could include rehabilitation of habitats, restoration of water quality, protection of breeding grounds and long-term ecological monitoring.

Standing, evidence and causation

A biodiversity claim must establish an appropriate legal basis and satisfy applicable procedural requirements. Public-interest litigation may permit concerned individuals or organisations to challenge environmental harm, while statutory proceedings may have their own eligibility and limitation rules.

Evidence may include ecological surveys, satellite imagery, species-population data, water and soil testing, expert reports, environmental clearance documents and records of the disputed activity. Where several activities contribute to ecological decline, proving causation and allocating responsibility may be particularly complex.

In A.P. Pollution Control Board v Prof. M.V. Nayudu (1999) 2 SCC 718, the Supreme Court discussed the challenges courts face when resolving environmental disputes involving specialised scientific and technical questions. The decision highlights the importance of reliable expert evidence and informed environmental decision-making.

This principle is especially relevant when claims concern cumulative impacts, threatened species or long-term ecosystem changes. Courts and tribunals must evaluate scientific material carefully rather than treating allegations of environmental harm as conclusive proof.

Remedies and accountability

Depending on the applicable law, biodiversity claims may seek:

Injunctions preventing unlawful activities or further ecological damage.

Review or cancellation of environmental approvals where legally justified.

Compensation for environmental harm and affected persons.

Restoration of damaged habitats and natural resources.

Directions requiring regulatory authorities to perform statutory duties.

Monitoring, reporting and compliance measures to prevent recurring damage.

The appropriate remedy should address the nature and extent of the harm. Restoration may be preferable to financial compensation where the ecological damage can realistically be repaired, although some losses may be irreversible.

Conclusion

Biodiversity claims provide legal mechanisms for challenging ecological destruction, enforcing conservation obligations and obtaining appropriate remedies for environmental damage. In India, constitutional environmental principles, the Biological Diversity Act, the Environment (Protection) Act, wildlife and forest legislation, and the National Green Tribunal Act collectively support biodiversity protection.

The decisions in M.C. Mehta v Kamal Nath, Vellore Citizens' Welfare Forum, Indian Council for Enviro-Legal Action, Hanuman Laxman Aroskar and A.P. Pollution Control Board v M.V. Nayudu establish important principles concerning public trust, precaution, environmental remediation, lawful assessment and scientific evidence.

Ultimately, successful biodiversity claims require a clear legal basis, credible evidence of ecological harm, an appropriate connection to the alleged responsible party and a remedy suited to the damage. Effective enforcement can help ensure that development and economic activity proceed consistently with ecological protection and the long-term public interest.
