Navi Mumbai’s Lotus Lake has once again become the centre of an environmental controversy as urban planners and citizen groups clash over whether the three-hectare waterbody in Nerul qualifies as a wetland or a developable plot. The City and Industrial Development Corporation (CIDCO) has been accused by environmental activists of attempting to reclaim the lake for real estate development, a move they say could destroy an ecologically sensitive zone and worsen the city’s flood vulnerability.
Despite an earlier directive from the State environment minister instructing the removal of debris dumped into the lake, the site remains partially filled with construction waste reportedly sourced from the Navi Mumbai International Airport project area. According to local organisations, no significant clean-up has occurred even after repeated public assurances. Citizen-led forums, including the Save Navi Mumbai Environment Forum, have held peaceful demonstrations and weekly marches demanding accountability from CIDCO. Activists argue that Lotus Lake, a seasonal habitat for lotus species and migratory birds, plays a vital role in maintaining the city’s ecological balance. “If these few remaining wetlands are lost, the city’s resilience against flooding will be severely compromised,” said one environmental campaigner involved in the movement.
CIDCO, however, maintains that the lake is an artificial, man-made feature created during earlier land reclamation and therefore does not fall under the definition of a natural wetland. In its response to the State environment department, the agency said the area is suitable for urban development and does not require protection under wetland conservation laws. Environmental experts disagree, citing the Ramsar Convention’s broader definition of wetlands, which includes both natural and artificial waterbodies that support aquatic biodiversity. They argue that the presence of aquatic vegetation, bird populations, and a functioning ecosystem qualifies Lotus Lake as a wetland under global and national frameworks.
The State environment department has confirmed that a ground-truthing exercise—conducted by the National Centre for Sustainable Coastal Management—has already verified the lake’s existence in the National Wetland Inventory and Assessment. This verification precedes formal notification of over 23,000 wetlands across Maharashtra. Urban planners note that the conflict illustrates a wider challenge facing fast-developing cities like Navi Mumbai: balancing infrastructure growth with ecological preservation. Experts suggest that authorities could adopt a “wetland integration” approach, incorporating natural assets into urban design rather than replacing them. Such strategies, they argue, are crucial for sustainable urbanisation and long-term climate resilience in coastal regions.
