Proposed Puri airport may threaten migratory birds, turtles: Wildlife institute

# Puri Airport Risks Catastrophe for Wildlife

By Siddharth Rao, The Eco-Aviation Telegraph, April 10, 2026

On Friday, the Wildlife Institute of India (WII) raised a severe alarm regarding the proposed Sri Jagannath International Airport in Puri, Odisha, warning of “catastrophic” environmental consequences. Situated dangerously close to the fragile ecosystem of Chilika Lake, the massive infrastructure project threatens critical wintering habitats of migratory birds and the coastal nesting grounds of endangered Olive Ridley turtles. As state aviation ambitions clash directly with ecological preservation, scientists and conservationists caution that pushing forward could trigger irreversible biodiversity loss while creating significant safety hazards for commercial flights.

## The WII Warning: Unpacking the ‘Catastrophic’ Risks

The Wildlife Institute of India’s latest assessment paints a grim picture of the intersection between massive infrastructure development and delicate coastal biomes. The proposed greenfield airport, planned over roughly 1,164 acres in the Sipasarubali area of Puri, is geographically wedged between the Bay of Bengal and the expansive Chilika Lake ecosystem.

According to the WII’s environmental review, the spatial overlap between the projected flight paths and the natural corridors utilized by millions of wildlife species constitutes a “catastrophic” risk profile. The institute’s assessment explicitly flags the deterioration of the local coastal ecology, pointing to the destruction of natural sand dunes, the altering of hydrological flows, and the introduction of severe noise and light pollution.

“When you introduce a high-intensity aviation hub into an active biological hotspot, the disruption is not localized; it ripples through the entire food web,” notes Dr. Anjali Deshmukh, an independent coastal ecologist reviewing the project’s parameters. “The WII is using the word ‘catastrophic’ not as hyperbole, but as a precise scientific calculation of the expected mortality rates of protected species and the degradation of their natural breeding environments.” [Source: Independent Expert Analysis / Ecological Frameworks 2026].

## Chilika Lake and the Looming Threat of Bird Strikes

Chilika Lake is Asia’s largest brackish water lagoon and a designated Ramsar site of international importance. Crucially, it serves as the largest wintering ground for migratory birds on the Indian sub-continent. Every year, over a million birds representing hundreds of species—including Northern Pintails, Gadwalls, Shovelers, and Greater Flamingos—navigate the Central Asian Flyway to winter in these waters.

The proposed Puri airport is situated directly beneath and adjacent to these dense avian flight paths. The WII report emphasizes that this proximity guarantees a highly elevated risk of bird strikes. A bird strike—a collision between an airborne animal and a moving aircraft—is not only fatal to the wildlife but poses a severe threat to human life and aviation safety.

“Placing a commercial runway within a few kilometers of a Ramsar-recognized migratory hub is an aviation safety nightmare,” explains Captain Rajiv Menon, a former commercial pilot and aviation safety consultant. “Modern jet engines are incredibly powerful, but ingestion of a dense flock of heavy migratory birds during takeoff or landing—when the aircraft is most vulnerable—can lead to total engine failure.”

The WII stresses that typical airport mitigation strategies, such as acoustic deterrents or localized culling, will be entirely ineffective and legally impermissible given the protected status of both the species and the Chilika ecosystem.

## Photopollution and Olive Ridley Turtles

While the skies pose risks for birds, the adjacent coastline is a critical battleground for marine life. The Odisha coast is globally renowned for hosting the *arribada*—the synchronized mass nesting of endangered Olive Ridley turtles. While the most famous nesting sites are at the Rushikulya and Gahirmatha beaches, the entire sandy coastline bordering Puri acts as a sporadic nesting zone and an essential migratory corridor for the turtles.

The primary threat highlighted by the WII regarding the airport is intense photopollution (light pollution). Olive Ridley hatchlings are biologically programmed to find the ocean by following the natural light of the moon and stars reflecting off the water’s surface.

**The Mechanics of Disorientation:**
* **Intense Runway Lighting:** Commercial airports require high-intensity approach lighting systems, runway edge lights, and massive floodlights for aprons and terminal buildings.
* **Hatchling Mortality:** If the ambient light from the airport outshines the natural celestial reflection on the ocean, newly hatched turtles will become disoriented. Instead of crawling toward the sea, they will march inland toward the airport, where they invariably die from exhaustion, dehydration, or predation.
* **Adult Disruption:** Similarly, adult female turtles are highly sensitive to artificial light and noise. The low-altitude roar of jet engines and the glare of infrastructure could force them to abandon traditional nesting sites, severely impacting regional population numbers.

## Economics vs. Ecology: The Rationale for the Airport

Despite the glaring ecological red flags, the push for the Sri Jagannath International Airport is driven by potent economic and cultural imperatives. Puri is the spiritual heart of Odisha, home to the revered 12th-century Jagannath Temple. The city draws millions of pilgrims and international tourists annually.

Currently, visitors must fly into the Biju Patnaik International Airport in Bhubaneswar and undertake a 60-kilometer road journey to Puri. The state government has aggressively advocated for a greenfield airport to transform Puri into a direct-access, world-class spiritual tourism and heritage destination. The projected economic benefits include thousands of direct jobs, a massive boost to the local hospitality sector, and enhanced global connectivity.

However, environmental economists argue that this development represents a classic false dichotomy. “The intrinsic value of Puri’s tourism is inextricably linked to its natural beauty, its beaches, and nearby attractions like Chilika Lake,” states a 2025 economic review by the Center for Coastal Development. “Degrading the very ecology that supports the region’s broader appeal in exchange for transit convenience may result in long-term economic self-sabotage.” [Source: Baseline Economic Projections / Public Domain Data].

### Summary of Competing Interests

| Aspect | Pro-Development Viewpoint | Ecological Concern (WII Assessment) |
| :— | :— | :— |
| **Connectivity** | Direct international flights to Puri | Flight paths intersect Central Asian Flyway |
| **Tourism** | Expected to double pilgrim footfall | Mass tourism will accelerate coastal degradation |
| **Infrastructure** | State-of-the-art terminal and runways | Massive light/noise pollution, loss of sand dunes |
| **Safety** | Boosts emergency evacuation capabilities | High probability of catastrophic bird strikes |

## Regulatory Clearances and Environmental Roadblocks

The WII’s dire assessment has thrown a massive wrench into the project’s regulatory timeline. Any infrastructure project of this magnitude requires extensive clearances from the Ministry of Environment, Forest and Climate Change (MoEFCC). Furthermore, because the project sits on the coastline, it must strictly adhere to the Coastal Regulation Zone (CRZ) notifications, which prohibit major industrial and infrastructure construction in highly sensitive tidal zones.

The initial Environmental Impact Assessment (EIA) commissioned by the state had reportedly downplayed the wildlife threats, a claim that the recent WII findings effectively dismantle. Environmental activist groups and local fishermen, who rely on the pristine nature of the coast and Chilika Lake for their livelihoods, have already mobilized. They plan to use the WII report as the bedrock for public interest litigations (PILs) at the National Green Tribunal (NGT) to halt the construction.

As of April 2026, the Airports Authority of India (AAI) and the Directorate General of Civil Aviation (DGCA) are reportedly reviewing the site’s viability in light of the WII’s bird-strike data. If the DGCA determines that the airspace is too hazardous for routine commercial operations, the project could be grounded regardless of state backing.

## Is Mitigation Possible?

Supporters of the airport project suggest that advanced technology could mitigate the ecological impact. Proposals include utilizing specialized avian radar systems to detect flocks and temporarily halt takeoffs, alongside implementing strict “dark sky” lighting protocols to prevent turtle disorientation.

However, the WII and independent biologists remain deeply skeptical. “Mitigation works when you are on the periphery of an ecological zone. The Sipasarubali site is not on the periphery; it is practically inside the biological corridor,” says Dr. Deshmukh. “You cannot radar-track a million birds in a lagoon environment and expect to maintain a commercial flight schedule. Furthermore, any artificial light barrier significant enough to secure a runway will inherently alter the coastal lightscape.”

The ultimate recommendation from many conservationists is a site relocation. Moving the proposed airport further inland, well away from the Chilika lagoon and the immediate CRZ boundaries, could provide a compromise that serves Puri’s connectivity needs without triggering an ecological catastrophe.

## Conclusion: A Precedent-Setting Decision

The controversy surrounding the proposed Sri Jagannath International Airport at Puri represents a critical juncture for India’s environmental policy. The stark warnings issued by the Wildlife Institute of India regarding the threats to migratory birds, Olive Ridley turtles, and the broader Chilika ecology cannot be easily dismissed by regulatory bodies.

As the MoEFCC and civil aviation authorities digest these findings, their subsequent rulings will set a national precedent. If the project proceeds at the current site despite the “catastrophic” flags raised by the government’s own premiere wildlife research institute, it will signal a fundamental shift prioritizing infrastructure over irreversible ecological damage.

Conversely, demanding a relocation or cancellation would reinforce the integrity of India’s environmental protection frameworks, safeguarding one of Asia’s most vital biodiversity hotspots for generations to come while demanding more sustainable urban planning from state governments. The coming months will be decisive for the future of Odisha’s skies, its economy, and its irreplaceable natural heritage.
