Birds Shun Polluted Waters
The eagerly anticipated arrival of flamingos in Navi Mumbai has been overshadowed by a disturbing ecological trend: the birds are actively avoiding key
wetlands in Nerul, once a reliable haven. Observers have noted flocks flying over lakes like DPS, NRI, and T S Chanakya, all linked to the Thane Creek Flamingo Sanctuary, but choosing not to land. Environmentalists interpret this behavior as a dire signal of deteriorating habitat quality. At the NRI jetty, only a handful of flamingos were seen at a considerable distance. Rekha Sankhala of the Save Mangroves and Flamingos Forum expressed concern, stating that residents witnessed flocks attempting to land but ultimately bypassing DPS lake due to unfavorable conditions. She emphasized that flamingos serve as crucial indicators of ecological health, and their avoidance of an area signifies a serious problem. The once vibrant spectacle of thousands of flamingos has dwindled, leaving a stark emptiness in its wake, a clear sign of environmental distress affecting these migratory birds and their vital ecosystem.
Toxic Waters Threaten Life
Recent water quality assessments have revealed critical levels of pollution, effectively eradicating the microorganisms that form the flamingo's primary food source. Comprehensive tests indicate severe ecological stress, with Total Dissolved Solids (TDS) registering nearly five times above safe limits and pH levels exceeding 9, pointing to highly alkaline water. More alarming is the collapse of oxygen levels, evidenced by Biochemical Oxygen Demand (BOD) and Chemical Oxygen Demand (COD) readings up to five times higher than healthy thresholds. Experts describe this as a 'suffocated' ecosystem, where the wetland is no longer a functional living system. B N Kumar, director of NatConnect, highlighted that disrupted water movement and the absence of tidal exchange prevent these habitats from sustaining life. He characterized the T S Chanakya wetland as a prime example of 'civic neglect,' referencing past judicial warnings to authorities regarding inaction on similar environmental degradation issues. The very sustenance of the wetland's inhabitants is compromised by these toxic conditions.
Blocked Tides Cause Crisis
A primary driver of this environmental decline is the obstruction of natural tidal flow. While seawater typically enters during high tide, elevated and blocked drainage channels now prevent its egress. This trapping of polluted water leads to the proliferation of harmful algal blooms, further degrading the habitat. Authorities have initiated remediation efforts through 'Operation DPS Flamingo Lake cleanup,' removing substantial amounts of sludge daily, with nearly four tonnes cleared to date. However, activists contend that these measures address only superficial symptoms. Kumar argues that manual desilting is not a sustainable solution, emphasizing that the problem will persist unless channels are deepened and natural water flow is reinstated. Social activist Jyoti Nadkarni echoed this sentiment, believing that restoring proper inlets and outlets would naturally revive the system, rendering clean-up drives less impactful without fundamental changes. The underlying issue of impeded natural water cycles remains a significant bottleneck.
Official Intervention Promised
The escalating environmental crisis has captured the attention of higher government levels. During a recent public grievance session, representatives from the Navi Mumbai Environmental Preservation Society, alongside local corporator Netra Shirke, brought the matter to the attention of minister Ganesh Naik. In response, Naik has instructed the Forest Department and the Navi Mumbai Municipal Corporation (NMMC) to accelerate sludge removal and resolve the issue of blocked inlets. A joint inspection of the affected wetlands is planned with the stated objective of restoring a clean and suitable habitat for flamingos promptly. Despite this administrative focus, critical obstacles persist. A key tidal inlet remains obstructed due to ongoing jetty construction, making the establishment of an alternative inlet imperative. Environmentalists have also pointed to coordination failures between the NMMC and CIDCO, both entities responsible for managing tidal flow. A proposal to designate the area as a Conservation Reserve is still pending with the Forest Ministry. Facing continued delays, residents are contemplating legal action, with plans to approach the National Green Tribunal if urgent corrective measures are not implemented. The absence of flamingos is considered undeniable proof of ecological collapse, a loss that could be irreversible within a human lifetime.
