"Climate vulnerable cities with dense population must get their act together to focus on climate adaptive mechanism. Sponge cities is one compelling alternative that must be taken seriously. Like, for instance, you can create huge stadium like structures with deep underground parking facilities which during summer act as recreational place while during flooding turns into water storage. Policy makers must take responsibility" (https://depalan.blogspot.com/2021/11/chennai-is-facing-brunt-of-climate.html).
As situation turns grim in India's megacity Mumbai there is an urgent need for policy makers to work for climate resilient cities. There are clear indications that we have well passed mitigative action stage. Densely populated coastal cities like Mumbai are at the forefront of unfolding climate disaster hence must take steps for climate adapted infrastructure. Retrofitting for climate resilient buildings and creating standby temporary structures during waterlogging are urgently needed. Functional recoverability of infrastructure is paramount. There are many innovative measures being taken across the world.
