The Odisha government has formally approached the Centre for financial and technical assistance to execute a major revival plan for Chilika Lake, Asia's largest brackish water lagoon. State Law, Works and Excise Minister Prithiviraj Harichandan and Puri MP Sambit Patra met Union Finance Minister Nirmala Sitharaman in New Delhi on Tuesday to submit a detailed proposal.
Central Collaboration Sought for Ecological Treasure
During the meeting at the finance minister's office, the Odisha delegation emphasized the need for a collaborative centre-state approach to secure the future of the lagoon. Minister Harichandan described Chilika as one of Odisha's greatest prides and treasures, highlighting its international status as a Ramsar wetland site. He pointed out that years of neglect have led to alarming degradation, threatening the ecosystem.
The discussions focused on long-term protection and restoration, considering the lake's immense tourism potential and its role as a livelihood source for millions of people dependent on its fisheries. Harichandan stated that reviving Chilika would not only boost the state's economy but also play a crucial role in broader environmental protection efforts for the region.
IIT Madras Roadmap Highlights Critical Challenges
The state government has already partnered with IIT Madras for a technical study, which has submitted a preliminary report outlining a science-driven roadmap. MP Sambit Patra noted that the study assessed emerging ecological challenges and proposed a comprehensive plan for sustainable restoration and management. He connected the lake's revival to India's environmental security and its alignment with the national Blue Economy vision.
The IIT Madras findings reveal a severe crisis:
- Massive siltation of approximately 8 lakh tonnes every year.
- Lake depth reduced to as little as 0.38 metres in some areas.
- Shifting of the lake's mouth, restricting seawater inflow and disrupting its delicate brackish water character.
The proposed roadmap recommends eco-friendly dredging to restore natural water exchange, control invasive weed growth, and revive biodiversity, including the iconic Irrawaddy dolphins and fish populations.
Path Forward: Detailed Project Report in the Works
Based on the study, a Detailed Project Report (DPR) is currently being prepared with continued technical support from IIT Madras. This DPR will guide the long-term protection and ecosystem revival strategy. Last month, State Forest and Environment Minister Ganesh Ram Singkhuntia informed the assembly about this crucial planning document.
Environmental experts stress that timely and coordinated action between the state and central governments is critical to safeguard this unique wetland. The future of Chilika Lake, a cornerstone of Odisha's ecological heritage and economic wellbeing, now hinges on the successful partnership and implementation of this science-backed restoration plan.
