Urban ponds play a critical role in sustaining ecological balance, enhancing urban resilience, and promoting community well-being. However, the rapid expansion of urban settlements has resulted in the gradual degradation and conversion of these water bodies, leading to significant environmental impacts, including biodiversity loss. This study investigates the transformation of urban pondscapes within Serampore Municipality, located in the Kolkata Metropolitan Area (KMA). A total of 191 ponds were identified and classified using Google Earth satellite imagery, field surveys, and statistical analysis. The ponds were categorized based on their size, condition, and usage, with field observations used to assess their health. Descriptive statistical methods were employed to analyze the distribution and size variations of these ponds. Additionally, secondary data on water quality parameters, such as turbidity and chlorophyll levels, were analyzed to evaluate the overall ecological health of the ponds. The results indicate a marked decline in the number of ponds, with nine ponds having been converted into built-up areas between 2011 and 2024. These findings underscore the adverse effects of urbanization on blue infrastructure and highlight the inadequacies of current policies in safeguarding urban water bodies. The evidence calls for stronger policy interventions and the adoption of sustainable urban planning practices to protect and conserve these vital aquatic resources. Without the proper management of urban ponds, the environmental and social functions they provide will continue to deteriorate, posing further risks to urban ecosystems and human health. Enhanced governance, alongside the integration of blue infrastructure into urban planning frameworks, is crucial for mitigating these challenges and ensuring the resilience of urban landscapes.
