A three-kilometer part of the Buckingham Canal in Tamil Nadu's Cuddalore district was once filled with plastic and waste. The water barely moved, and the canal could no longer function as a waterway.
However, The Tamil Nadu Forest Department, with help from the community, has brought the canal back to life. They planted 20,000 mangrove seedlings and cleared tons of plastic.
Bringing a Choked Canal Back to Life
The first step was to tackle the massive amount of waste. About 600 villagers worked together to remove nearly 750 kg of plastic from the canal. This waste was then given to the Killai Town Panchayat for proper disposal.

Then came the planting. Mangrove species like Rhizophora mucronata, Rhizophora apiculata, Avicennia marina, and Avicennia officinalis were planted along both sides of the canal. These trees help stabilize the shorelines and improve water flow.
The project also includes an innovative "fishbone" structure. This design helps create healthy tidal flow, which is crucial for mangroves to grow. According to IAS Supriya Sahu, "8 main fishbone canals have been created with 8 feeder canals and 186 distribution channels." This system ensures good water circulation for the young trees.
Restoring Flow and Life
The restoration has already made a difference. Officials say water now circulates better into the Pichavaram mangroves, making the ecosystem stronger. This also helps about 50 Irula tribal fishing families, as fish populations are starting to recover, providing them with more stable livelihoods.
Supriya Sahu noted that the canal, once full of plastic and garbage, has bounced back. She highlighted the 3 km of rejuvenated canal, 750 kg of plastic removed, and 3,000 mangroves planted with community help. This effort has created a thriving ecosystem and strengthened coastal resilience.
The Cuddalore district administration led this initiative, working with the Forest Department and other groups. Forest Range Officer Iqbal oversaw the work on the ground, supported by District Collector Sibi Adhithya and other senior officials.
A Model for Other Cities
This project stands out because of its approach. It started with clearing waste and restoring water flow, steps often overlooked. Restoration doesn't end with just planting. Mangroves need ongoing protection, and canals must stay clear to prevent the same problems from returning.
Many canals across India face similar issues, becoming clogged with garbage and slowing down. This project on the Buckingham Canal offers a different way forward. It shows that starting with cleanup and restoring natural flow, then involving local communities, can lead to lasting change. This simple approach can be followed by any city.
