Kaziranga Eco-Sensitive Zone Debate

Syllabus: GS III & V— Environment & Biodiversity

Why in the news?

The debate over the Eco-Sensitive Zone around Kaziranga National Park and Tiger Reserve has intensified after the Assam Government proposed reducing the zone from the default 10 kilometres to around 1–3 kilometres. The issue has gained further importance following the International Union for Conservation of Nature World Heritage Outlook 2025, which rated Kaziranga “Good with Some Concerns” and highlighted pressures from unplanned infrastructure, tourism, land-use change, climate change and habitat fragmentation. The central question is not simply “1 kilometre or 10 kilometres?” but rather: How can Kaziranga’s wider ecological landscape be protected while respecting the rights and livelihoods of local communities?

What is an Eco-Sensitive Zone?

An Eco-Sensitive Zone is a regulated area around protected areas that works as a “shock absorber” between highly protected ecosystems and areas of intensive human activity.

• The 2011 Eco-Sensitive Zone Guidelines provided for site-specific identification of such zones, with a general guideline of up to 10 kilometres around protected areas.
• Ecologically important wildlife corridors, connectivity patches and landscape linkages can require protection beyond the general distance-based approach.
• Activities within an Eco-Sensitive Zone are broadly classified as prohibited, regulated and permitted activities.

Important legal point

The Supreme Court initially directed the maintenance of a minimum one-kilometre Eco-Sensitive Zone around protected forests, national parks and wildlife sanctuaries. However, it later recognised that a uniform one-size-fits-all approach is not appropriate and allowed site-specific circumstances to be considered. Therefore, the 10-kilometre figure should not be understood as a compulsory ecological width for every protected area.

Why is Kaziranga particularly sensitive?

Kaziranga is not an isolated forest. It is a dynamic floodplain ecosystem whose ecological processes extend beyond its notified boundary.

• Kaziranga is a UNESCO World Heritage Site and is internationally recognised for its exceptional biodiversity.
• It supports the one-horned rhinoceros, along with tigers, elephants, wild water buffalo, swamp deer and numerous bird species.
• The annual floods of the Brahmaputra play an important ecological role by replenishing wetlands, renewing grasslands and maintaining the floodplain ecosystem.
• However, during severe floods, animals move towards higher ground in the Karbi Anglong hills.

This makes the Kaziranga–Karbi Anglong ecological connection extremely important.

Major concerns highlighted by the IUCN assessment

The 2025 assessment identified several pressures on Kaziranga:

• Unplanned infrastructure and tourism: Resorts, commercial construction and tourism infrastructure can increase ecological pressure around the park.
• Habitat fragmentation: Changes in surrounding land use can obstruct important animal movement routes.
• Karbi Anglong connectivity: The hills provide important flood-time refuge and extended habitat for wildlife.
• Mining and quarrying: Stone mining, quarrying and related activities can damage forests, slopes, drainage systems and wildlife corridors.
• Climate change: Changing rainfall patterns and intensified floods can increase risks to wildlife and infrastructure.
• Invasive species: Species such as Mikania micrantha and Eichhornia crassipes threaten native ecosystems.
• Human–wildlife conflict: Wildlife moving outside the park during floods increasingly comes into contact with roads, settlements and agricultural areas.

The assessment therefore emphasises adaptive conservation, community partnerships and integrated landscape-level planning.

Why a blanket 10-kilometre zone is not necessarily the solution

A wider Eco-Sensitive Zone is not automatically more effective if it is poorly designed or poorly enforced. Villages, farmland, tea gardens, roads, tourism facilities and private land already exist around Kaziranga. A uniform boundary could place unnecessary restrictions on relatively less-sensitive areas while failing to protect a wildlife corridor or wetland located farther away. Therefore, Kaziranga needs a variable-width, science-based Eco-Sensitive Zone.

Where protection should be stronger

• The Eco-Sensitive Zone should be wider around wildlife corridors, particularly routes connecting Kaziranga with Karbi Anglong.
• Greater protection should be provided to wetlands, beels, drainage channels, flood routes and connected forest patches.
• Mining, quarrying, stone crushers and polluting industries should face strict restrictions in ecologically sensitive areas.
• Areas with established settlements and limited ecological connectivity may require a narrower and more flexible approach, subject to scientific evidence and public consultation.

Balancing conservation and local livelihoods

Local communities should not be treated as obstacles to conservation. They often bear the costs of conservation through crop damage, livestock losses, human–wildlife conflict and restrictions on land use. A sustainable approach should therefore include:

• Participatory mapping of wildlife corridors, wetlands, settlements and livelihood areas.
• Publishing proposed maps and restrictions in Assamese and other local languages.
• Involving local communities in Eco-Sensitive Zone planning and monitoring.
• Promoting community-based tourism and homestays so that tourism benefits reach local households.
• Supporting traditional livelihoods, handicrafts and environmentally sustainable agriculture.
• Creating integrated waste and sewage management systems in tourism centres and surrounding settlements.

Regulating tourism sustainably

Tourism provides employment and income, but uncontrolled tourism can itself become an ecological pressure. Tourism planning around Kaziranga should consider:

• Number of visitors and safari vehicles.
• Groundwater consumption and waste generation.
• Sewage and sanitation capacity.
• Construction of hotels and resorts.
• Noise and disturbance to wildlife.
• Share of tourism income reaching local communities.

The objective should be “quality tourism rather than merely more tourists.”

Towards a landscape-level approach

An Eco-Sensitive Zone alone cannot protect Kaziranga. A Kaziranga Landscape Planning Committee involving government departments, local bodies, village institutions, communities, tourism stakeholders, scientists and independent experts could help prepare an integrated plan. The plan should map: Wildlife corridors + Forest cover + Wetlands + Flood routes + Drainage systems + Settlements + Land use + Mining areas + Tourism infrastructure It should also assess the cumulative impact of roads, mining, resorts, tourism facilities and other infrastructure instead of evaluating every project in isolation.

Way Forward

The following approach can make the Kaziranga Eco-Sensitive Zone both ecologically effective and socially acceptable:

• Adopt variable-width zoning instead of relying only on a fixed distance.
• Keep wildlife corridors open, especially routes towards Karbi Anglong.
• Restore wetlands and natural drainage channels that support the floodplain ecosystem.
• Strictly regulate mining, quarrying and habitat-damaging construction.
• Strengthen community participation in conservation decisions.
• Introduce transparent tourism carrying-capacity assessments.
• Prepare a Zonal Master Plan with measurable conservation targets.
• Ensure annual compliance monitoring and public reporting.
• Use scientific evidence and local consultation before finalising the boundary.

Conclusion

The Kaziranga debate should not become a simplistic contest between “10 km versus 1 kilometre.” A good Eco-Sensitive Zone is not necessarily the widest one. It is one that protects the right ecological areas, regulates harmful activities, respects legitimate community needs and can actually be enforced. For Kaziranga, conservation must extend beyond its formal boundary to include its floodplain, wetlands, surrounding forests and wildlife corridors. The future lies in moving from park-centric conservation to landscape-level conservation, where biodiversity protection, climate resilience and human development are planned together.

Key Takeaways

• Eco-Sensitive Zones are regulatory buffers, not blanket no-development zones.
• The Kaziranga–Karbi Anglong corridor is crucial for wildlife movement during floods.
• Kaziranga faces pressures from land-use change, tourism, infrastructure, mining, invasive species and climate change.
• Variable-width, landscape-based zoning can be more effective than a uniform boundary.
• Local communities must be conservation partners, not merely subjects of regulation.

Exam Hook – Mains

“A uniform Eco-Sensitive Zone cannot adequately address the ecological and socio-economic realities of Kaziranga.” Discuss the need for a landscape-level approach to conservation. One-line wrap: Kaziranga needs not merely a wider buffer, but a smarter, science-based and community-supported conservation landscape.
