Introduction
India's civil aviation sector is among the world's fastest-growing, with domestic passenger traffic exceeding 150 million annually and the government targeting 220 airports under UDAN by 2026. However, rapid airport expansion is increasingly colliding with ecological red lines — protected wetlands, wildlife corridors, and migratory bird routes. The proposed Shree Jagannath International Airport at Puri, Odisha, has become a landmark case: the Wildlife Institute of India (WII) has issued a rare outright rejection of the project, citing both ecological harm and direct aviation safety risks near Chilika Lake, a Ramsar-designated wetland of international importance.

Background
| Parameter | Details |
|---|---|
| Proposed airport | Shree Jagannath International Airport, Puri |
| Location | Sipasurubali village, Brahmagiri tehsil, Puri district |
| Total land required | 471.401 hectares |
| Non-forest land | 443.514 hectares |
| Forest land (Wildlife Division) | 27.887 hectares |
| Clearances already issued | Ministry of Civil Aviation — site clearance |
| Existing airport | Biju Patnaik International Airport, Bhubaneswar |
| WII recommendation | Against the project |
Why the Airport Was Proposed
The Odisha government and Airports Authority of India (AAI) jointly pushed for the Puri airport on the ground that Biju Patnaik International Airport in Bhubaneswar lacks sufficient land for runway expansion to meet projected passenger growth. Puri's religious tourism significance — as the seat of the Jagannath Temple, one of India's most visited pilgrimage sites — further strengthened the demand case.
Why WII Rejected It — Two Distinct Grounds
1. Ecological concerns
- Chilika Lake, located in close proximity to the proposed site, is India's largest coastal lagoon and a Ramsar site — a wetland of international importance under the Ramsar Convention (1971), to which India is a signatory
- Chilika hosts over 10 lakh migratory birds from Central Asia, China, and Siberia every winter — including flamingos, herons, and rare species
- The Puri coast is a critical habitat for Olive Ridley sea turtles (Schedule I, Wildlife Protection Act) and Irrawaddy dolphins — both threatened species
- Airport construction would disrupt migration routes and nesting habitats irreversibly
2. Aviation safety concerns
Large concentrations of migratory birds near airports create severe bird-strike risks. WII cited two recent precedents:
| Incident | Airport | Distance from Ramsar Site | Outcome |
|---|---|---|---|
| December 29, 2024 | Muan International Airport, South Korea | 9 km from Muan Tideland | 179 human casualties — collision with migratory Baikal Teals |
| Recent | Bahir Dar International Airport, Ethiopia | 4 km from Lake Tana | Bird-strike incident |
This dual grounding — ecology and safety — makes WII's rejection unusually robust and difficult to override.
Regulatory and Legal Framework
- Ramsar Convention (1971): India has 89 Ramsar sites; Chilika was among the first two designated in 1981. The convention requires signatory nations to avoid ecological degradation of listed wetlands.
- Wildlife Protection Act, 1972: Olive Ridley turtles listed under Schedule I — highest protection.
- Forest Conservation Act, 1980: Diversion of 27.887 hectares under Wildlife Division jurisdiction requires Forest Advisory Committee (FAC) approval — which triggered the WII referral.
- Environment Protection Act, 1986: Coastal Regulation Zone (CRZ) norms apply to Puri's coastal location.
- Aircraft Act, 1934 / DGCA Regulations: Bird hazard management is a mandatory safety consideration for airport site clearance.
Significance of WII's Recommendation
Environmental lawyer Shankar Pani has noted that an outright rejection by WII is rare — the institute typically flags concerns rather than opposing projects categorically. The dual basis (ecological + safety) gives the recommendation exceptional legal and scientific weight, making it difficult for the Ministry of Civil Aviation or state government to proceed without addressing both dimensions comprehensively.
Broader Policy Implications
- Raises the question of whether aviation infrastructure planning in India adequately integrates ecological sensitivity mapping at the site-selection stage — before clearances are issued
- The Ministry of Civil Aviation had already issued site clearance before ecological assessment was complete — a sequencing failure in the regulatory process
- Highlights tension between UDAN scheme (regional connectivity ambition) and wetland conservation obligations under international treaties
- Sets a precedent for how WII recommendations interact with sectoral ministry clearances — and which takes precedence
Way Forward
- Explore expansion alternatives at Bhubaneswar airport through vertical or technological solutions (multi-level parking, terminal redesign) before greenfield development
- Commission a Strategic Environmental Assessment (SEA) for all proposed airports within 20 km of Ramsar sites
- Establish a mandatory ecological pre-screening stage before aviation ministry site clearances are issued
- Consider Cuttack or inland Odisha locations as alternative sites with lower ecological sensitivity
Conclusion
The Puri airport controversy is not simply a conflict between development and environment — it is a failure of integrated planning. The fact that a site clearance was issued before ecological assessment was completed exposes a systemic gap in India's infrastructure approval architecture. Chilika Lake is not merely a local asset; it is an internationally recognised ecological commons. Protecting it is both a treaty obligation and a moral imperative. At the same time, Odisha's aviation infrastructure needs are real. The answer lies not in choosing between the two, but in designing smarter — finding solutions that do not demand ecological sacrifice as the price of connectivity.
