Restoring Urban Lakes as Climate Sponges Demands Ecological Repair Over Cosmetic Fixes

Gist The rapid disappearance and degradation of India's urban lakes have transformed critical climate buffers into vulnerable real estate. While national schemes like the Jal Shakti Abhiyan exist, their impact is routinely diluted by fragmented governance and a flawed municipal focus on cosmetic beautification over genuine ecological repair. For civil service aspirants, understanding this transition from viewing lakes as "vacant land" to essential "sponge systems" is crucial for answering questions on urban flooding, heat islands, and climate resilience. Background Wetlands cover nearly 6% of the planet's surface and function as highly productive ecosystems, often sequestering more carbon per unit area than terrestrial forests. Historically, lakes in Indian cities acted as functional civic assets, natural catchments, and flood moderators. However, as peri-urban land prices multiplied over the past five decades, these water bodies mutated into prime real estate. Developers and municipal bodies increasingly view them as "opportunity costs" rather than critical ecological infrastructure, making them vulnerable to systemic encroachment, untreated sewage dumping, and heavy eutrophication. Key Pointers Economic incentives vs. Ecological infrastructure: The exponential rise in urban land prices has economically…
