On 5 April 2026, the Government of Madhya Pradesh stated that turtle species conserved in the National Chambal Sanctuary are being deployed in stretches of the Ganga under the Namami Gange Programme as part of efforts to support ecological restoration.
As part of this initiative, 20 Red-Crowned Roofed Turtles (Batagur kachuga) were released in April 2025 into the Haidarpur Wetland and adjoining river stretches in Uttar Pradesh. These species are known to feed on decomposed organic matter and carrion, contributing to natural cleaning processes in aquatic ecosystems.
According to government statements, such biological interventions are intended to complement ongoing pollution control and river rejuvenation measures, with turtles playing a role in maintaining ecological balance and biodiversity.
Impact on River Health and Biodiversity
Ecosystem-based waste removal: Turtle species such as Batagur and Batagur dhongoka consume organic waste and dead matter, supporting natural decomposition processes in river systems.
Water quality improvements (multi-factor): Data cited by the Ministry of Jal Shakti indicates declining fecal coliform (FC) levels at locations such as Assi Ghat—from 2500 MPN/100 mL (2014) to 790 MPN/100 mL (2025)—alongside broader river cleaning interventions.
Improved oxygen levels: Dissolved Oxygen (DO) levels in several stretches are reported above 5 mg/l, supporting aquatic life.
Species survival and adaptation: A survival rate exceeding 50% in the Haidarpur Wetland suggests initial adaptation of relocated turtles to the new habitat.
What is "Namami Gange"?
Namami Gange is a flagship programme of the Government of India aimed at the rejuvenation of the River Ganga, with a focus on pollution abatement and ecosystem conservation.
The programme combines infrastructure-based interventions, such as sewage treatment plants and riverfront development, with ecological measures, including biodiversity conservation and habitat restoration. These efforts are designed to improve water quality, river flow, and overall ecological health.
It reflects an integrated approach to river management, where engineering solutions and nature-based interventions are used together to support long-term river restoration.
Policy Relevance: Biology as a Tool for Governance
Reduces the Need for Chemicals: Using turtles to consume organic waste is a "Green Tech" approach. It transposes expensive, energy-heavy cleaning processes into a self-sustaining cycle where nature manages its own waste.
Protects Endangered Gene Pools: The Chambal River is one of the few places on earth where nine rare turtle species thrive. Moving them to the Ganga ensures their survival in multiple locations, protecting them from localised extinction.
Boosts Eco-Tourism Revenue: Improvements in river health and biodiversity may support eco-tourism and livelihood opportunities, particularly in riverfront cities with existing tourism bases.
Empowers Local Communities: The survival of these "Aquatic Warriors" depends on local fishermen and villagers protecting them, turning everyday citizens into guardians of the river's health.
Relevant Question for Policy Stakeholders: What safeguards are in place to prevent mortality risks, such as fishing net entanglement or poaching, in urban stretches of the river?
