A win for the green at Chilika


Featured post on IndiBlogger, the biggest community of Indian Bloggers


Its a win for the environmental cause. It is also a slap in face for all those who promote mindless fancy projects in name of tourist promotions. The Airports Authority of India (AAI) has been forced cancel the water aerodrome project at the Chilika lagoon following objections from various quarter. However in a face saver it has offered to develop the project in Odisha if the state government provides it with an alternative site. Chilika, the second largest brackish water lake in the world, covers Khurda, Puri and Ganjam districts of Odisha. Situated at the mouth of the Daya River, Chilika is rich in biodiversity and a major tourist attraction in the state.

AAI chairman Guruprasad Mohapatra said: “Following a request from the state government to cancel the project as it would affect Chilika’s ecology, we have cancelled the project.” Making it clear that the AAI wants development of the state, Mohapatra said: “If the state government gives any proposal to develop a water aerodrome in the state, we will provide them all help. However, they have to submit the proposal within three weeks.” In June, the AAI had announced to set up aerodrome projects in Odisha, Gujarat, Maharashtra, Andhra Pradesh and Assam. Chilika in Odisha was the preferred site. The civil aviation ministry had given its nod to the Chilika proposal. The ministry also cleared Gujarat’s Sardar Sarovar Dam and Sabarmati River Front for similar projects in the first phase. But it is said that ministry didn’t consult all concerned stakeholders before giving the nod. If sources are to go by, the Ministry only took into consideration data and information related to tourism at Chilika but did not take on board the key stakeholder, Forest and Environment Department of the State. Although there has been claims by the the Civil Aviation Ministry about a joint team conducting a study, Chilika Development Authority (CDA) was apparently not consulted.

In a letter to chief secretary A.P. Padhi, the AAI chairman had said: “The Airports Authority of India plans to set up water aerodromes. For starting amphibious aircraft operation in Odisha, Bhubaneswar airport and Chilika lake have been shortlisted for a pre-feasibility study. The government will identify the site in Chilika.” Odisha initially had not objected to the proposal. A team of experts from the Centre had visited the area and conducted a study. Subsequently, environmentalists and the Chilika Development Authority (CDA) raised objections. BJD leader from Chilika area and Brahmagiri MLA Sanjay Das Burma and Khurda MLA Rajendra Sahu had objected to the proposal. BJP had slammed BJD for opposing the Centre’s efforts to boost employment in the area. However, the saffron party’s own MLA Dilip Ray had supported the BJD.

In a letter to the state government, chief executive, CDA, Sushanta Nanda had said: “Operation of seaplane and water aerodrome at Chilika, the world’s second largest brackish water lake, is likely to cause irrevocable damage to the ecosystem and livelihood of people dependent on it. The cost involved in the operation of seaplane seems to outweigh the benefits likely to accrue from it. Besides, legally the project is not feasible.” The operation of the aerodrome at any given location in the lake will have far reaching adverse consequences on its fragile ecosystem, the CDA maintained. He had also said: “The legal provisions under Wetland Conservation and Management Rule, 2017, are applicable to the internationally acclaimed Chilika wetland site. The rules strictly prohibit its conversion for non-wetland use. Construction of aerodrome is therefore not legally permissible as Chilika is a wetland site.” Such an aerodrome would require water runway for landing and take-off while associated facilities would have to be developed for docking sea aeroplanes, taxiway, apron, tourists’ entry check-in, re-fuelling, beacon lighting, offices, staff buildings among many things.

“Chilika is ecologically too fragile and precious for such experiments. Besides direct risks that are associated with plying aircraft in an area known for its mass congregation of birds, fuel and lubricant spills, emissions, noise pollution etc, ancillary development that will precede and follow the setting up of an aerodrome will only negatively impact the lake’s ecology,” says conservationist Aditya Chandra Panda.

The CDA maintained: “With one million birds congregating in the lake, the operation of seaplanes will be hazardous to winged species as they will either be sucked in the engines or be hit by the planes during its landing. The possibility of bird hit will also pose a threat to air travellers.” For six months between October and March, Chilika turns into a temporary habitat for lakhs of migratory and residential birds. The lake is home to 230 bird species, of which 97 are intercontinental migrants from Arctic and Eurasian regions. It saw congregation of close to 9 lakh birds during the last winter. For a majority of resident bird species, the 1100 sq km lagoon is a prime breeding site. It also holds a notified protected area, Nalabana Bird Sanctuary, which is spread over 15 sq km. The lake supports over 225 birds, 260 fish apart from 37 reptile and amphibian and 18 mammal species besides a large varieties of flora.

According to CDA, the birds are not only a major tourist attraction, but also help to recycle nutrients back into the ecosystem through “guano deposits”. Guano, the accumulated excrement of seabirds, is rich in nitrogen, phosphates and potassium- nutrients that spur the growth of vegetation. When birds forage the water, the vegetation in it thins and enables free movement of fish. If the bird population shrinks, livelihood of about two lakh fishermen dependent on Chilika is at risk, the report warns. Moreover, seaplanes have limited passenger carrying capacity which means that such a project may not add significantly to tourism. Besides, Chilika is extremely well-connected by road communication.

The CDA had cited that noise from the flights would distract the Irrawady dolphins, an endangered species found in the lake, which have highly sensitive hearing. Noise pollution generated by close to 10,000 boats has already taken a toll on the endangered Irrawaddy dolphins in the lake. The amphibious aircraft operation would have add to the woes. As many as 155 endangered Irrawaddy dolphins were spotted in Chilika, which is the single largest habitat of this species in the world and is also one of two lagoons in the world that shelter them. After clearing the lake of illegal man-made enclosures, dolphins have now started moving freely in all sectors. Meanwhile, the Odisha government has decided to regulate boat operation in the lake following the death of six passengers in a recent boat tragedy. It has made life jackets mandatory for tourists and GPS on the boats.
