Eco-Sensitive Zones and Land Purchase: What to Check

What an Eco-Sensitive Zone Is and Where the Power Comes From

An eco-sensitive zone is an area around a protected area, such as a national park or wildlife sanctuary, that the Ministry of Environment, Forest and Climate Change (MoEFCC) notifies so that development nearby does not damage the protected area. The legal basis is the Environment (Protection) Act, 1986 and the Environment (Protection) Rules, 1986, under which the Central Government can restrict industries, operations and processes in specified areas. The Ministry issued guidelines in 2011 for declaring such zones around protected areas, and later procedural office memoranda, which the Supreme Court has directed should be followed.

An ESZ is not a protected area itself and is not a forest in the legal sense. It is a regulatory overlay. The notification usually fixes the extent of the zone, which can vary from a few hundred metres to several kilometres in different directions, and lists activities as prohibited, regulated or promoted. It normally requires a zonal master plan, prepared by the state with local input, which sets out land use inside the zone; if you are new to such plans, see how to read a master plan. Where such a plan is not yet in force, the notification's own list usually governs.

The overlay differs from forest law. The Forest Conservation Act deals with the legal character of land that is forest; our guide to forest land and the Forest Conservation Act explains how that works. An ESZ can cover private farmland that is not forest at all. A plot can be outside any forest, inside an ESZ, and still face limits on what you can build.

The Supreme Court and the One-Kilometre Rule

Two orders in the long-running T.N. Godavarman Thirumulpad v. Union of India matter shape the current picture. On 3 June 2022 a three-judge bench directed, in summary, that national parks and wildlife sanctuaries should have an eco-sensitive zone of at least one kilometre measured from the boundary of the protected area, that mining within that one-kilometre belt would not be permitted, and that existing activities in the zone would need to be reported to the chief wildlife authority. The order caused immediate concern for residents and builders near sanctuaries.

On 26 April 2023 a bench of Justices B.R. Gavai, Vikram Nath and Sanjay Karol modified it. As reported, the Court exempted protected areas for which an ESZ had already been finally notified or for which a draft notification existed, and exempted areas that fall on inter-state borders or shared boundaries. It maintained the bar on mining within one kilometre of the boundary, required that final notifications observe a notice period before taking effect, allowed aggrieved parties to approach the Court directly, and told authorities to follow the 2011 guidelines and the 2022 office memorandum procedure.

What this means for a buyer is that there is no single rule you can apply from memory. Where a notification exists, it governs. Where none exists and the exemption does not apply, the one-kilometre direction may be relevant. Orders in this area can be clarified or developed in later hearings, so ask a lawyer for the current position rather than quoting 2022 or 2023 headlines.

What ESZ Rules Typically Restrict

Each notification is different, so read the one for your protected area. A typical structure, and the examples a notification may list, is:

• Prohibited activities. Commercial mining and stone crushing, setting up industries that cause pollution, large hydroelectric projects and sometimes the commercial use of firewood or other forest produce.
• Regulated activities. New hotels and resorts, construction of new commercial or residential structures, felling of trees, use of groundwater, change in land use, and electrical or road works. These are usually allowed only with permissions and sometimes with conditions on height, footprint and materials.
• Promoted activities. Organic farming, rainwater harvesting, local-material housing and eco-tourism practices that the notification encourages.

That is a pattern, not a rule for any one park. The corridor Farmland India covers includes protected areas in several states, for example Jim Corbett and Rajaji in Uttarakhand, Sariska and Ranthambore in Rajasthan, Dudhwa in Uttar Pradesh and Sultanpur in Haryana. Whether and how each is notified, and what a given notification says, must be checked directly. Do not assume that a farmhouse allowed in the next village is allowed in yours.

Interaction with other permissions also matters. A building plan approved by a local authority may still need ESZ clearance if the plot is inside the zone, and a change of land use (CLU) order under state law does not substitute for it. See our overview of farmhouse construction norms for how setbacks, coverage and approvals interact.

How to Check Whether a Plot Is in an Eco-Sensitive Zone

Treat this as a distinct step in your due diligence checklist:

• Identify the nearest protected areas. If the plot is within a few kilometres of any national park, sanctuary, conservation reserve or similar area, assume the question applies until shown otherwise.
• Find the notification. Search the MoEFCC website (moef.gov.in) and the Gazette of India for the protected area's final or draft ESZ notification. State wildlife departments and the PARIVESH portal (parivesh.nic.in) may also carry notifications and maps. Note whether it is draft or final, and its date.
• Read the boundary description. Notifications describe extent by distance in each direction, with village lists and sometimes coordinates or a map. Check whether your village and khasra number are named.
• Locate the plot against the map. Use the cadastral map and, if possible, a surveyor's coordinates, to see whether the plot is inside the boundary. Our guide to land demarcation and nishandehi explains how boundaries are fixed on the ground.
• Ask the authorities. Write to the Divisional Forest Officer or chief wildlife warden for the area, quoting village and khasra, and ask whether the plot is inside an ESZ and whether a zonal master plan applies.
• Get the seller to disclose. Put a representation in the agreement that the seller knows of no ESZ restriction or pending notice, and that any restriction found before registration allows you to withdraw.

Practical Risks and Safer Ways to Proceed

The main risk is not that the land is unusable. It is that your plan, whether a farmhouse, resort, warehouse or layout of plots, is not allowed or is delayed. The risk is higher for projects marketed on the strength of a nearby sanctuary: a seller may promote proximity to a forest as a selling point while the same proximity creates the restriction.

Where a plot is inside an ESZ, a few approaches are common. You can confine your plan to agriculture and uses the notification promotes; you can check, before signing, whether a local-authority building approval and an ESZ-related permission are realistic for your design; and you can build the agreement so that part of the price is payable only after the written position is received. If a draft notification exists but is not final, ask a lawyer how it treats existing and new construction, because a final notification can narrow what is allowed.

Pending litigation is another place to look. Notifications and boundaries are sometimes challenged, and orders can change. Our guide on checking land for litigation and court disputes covers how to search for cases touching your land. Also confirm that there is no forest-department notice for tree felling or encroachment on the plot.

Finally, remember that proximity can also help. Land near a protected area often retains greenery, lower density and agricultural character, which some buyers value. The aim of the check is to buy with open eyes, not to avoid every such plot.
