Ahmedabad’s urban lakes, a vital lifeline for the city’s ecological balance, are failing to benefit from heavy rainfall due to their lack of direct connectivity with catchment areas, revealed a study by Cept University. Despite experiencing severe flooding in three of the past five years, these waterbodies remain largely disconnected from the natural rainwater flow, diminishing their potential to recharge. The study, conducted across 500 square kilometres of Ahmedabad, mapped 45 lakes, revealing disparities in their size and distribution, with only four exceeding 50,000 square metres.
The findings highlight critical urban challenges. Poor connectivity and rapid urbanisation have left the city with just one lake per 17 square kilometres. While lakes play a vital role in mitigating urban flooding by accommodating rainwater runoff, their compromised condition exacerbates flood risks. The study also noted poor water quality in most larger lakes, making them unsuitable for aquatic ecosystems. Researchers linked larger lakes with higher property values, underscoring the socio-economic impact of well-maintained waterbodies.
From a civic perspective, the degradation of lakes points to the urgent need for better urban planning and stricter regulations to safeguard natural resources. Threats such as pollution, fragmentation, and unchecked human activity have led to their shrinkage. Planned lakefront developments could serve as hubs for social and recreational activities, enhancing community engagement.
On a sustainability front, preserving waterbodies aligns with long-term urban resilience. Lakes not only combat urban flooding but also contribute to groundwater recharge and climate adaptation. Promoting blue cover alongside green cover is crucial for sustainable development. Without immediate interventions, the city risks losing critical natural buffers, jeopardising both its environmental health and its ability to combat climate challenges effectively.
