Rabindra Sarobar gets 1.76 Cr fund for eco-friendly bank reinforcement using tree trunks

The West Bengal government has allocated 1 crore 76 lakh rupees for the reinforcement of Rabindra Sarobar's banks with an environmentally sustainable method. The project will be carried out by the Kolkata Metropolitan Development Authority (KMDA) with a completion deadline of six months. The chosen method involves using tree trunks to reinforce the lake’s embankments, an eco-friendly alternative aimed at preserving the lake’s delicate ecosystem.

Rabindra Sarobar, located in the heart of South Kolkata, covers an area of 73 acres and is recognized for its significant ecological value. The lake, which received national lake status in 2003, is home to over 12 species of aquatic life and 75 plant species. It serves as a critical urban green space, offering a habitat for various species while helping maintain the region’s ecological balance. The decision to reinforce the banks with tree trunks aims to address ongoing concerns about erosion and environmental degradation while maintaining biodiversity.

The tree trunk reinforcement method was selected over stone or concrete alternatives due to its minimal impact on the lake’s ecosystem. Tree trunks, particularly from native species like sal, banyan, mango, jackfruit, and others, will be used to create a natural barrier along the embankments. This method is expected to prevent further erosion while allowing the aquatic species and plant life to continue thriving. Tree trunks provide structural integrity without disrupting the habitat of the lake’s inhabitants.

The use of natural materials is crucial for maintaining the balance of aquatic life in Rabindra Sarobar. Environmentalists and experts have long expressed concerns that artificial materials, such as stones or concrete, could harm the habitat by blocking the movement of aquatic creatures and altering the lake’s ecosystem. In contrast, tree trunks offer a non-invasive solution that reinforces the embankments while preserving the water body’s natural features.

Rabindra Sarobar also plays an important role in the management of water quality and flood control in the region. Environmentalists have called for consistent efforts to protect the lake from pollution and waste accumulation. The ongoing initiative is part of a broader strategy to safeguard the lake’s biodiversity and ensure its environmental health for future generations. With the reinforcement work set to begin shortly, the project is expected to set a precedent for other urban water bodies facing similar environmental challenges.
