Urban flooding is a problem long associated with Mumbai. With a steady increase in the occurrence and severity of extreme weather events, Mumbai has lost that relative exclusivity, with Chennai and now Bangalore revealing a propensity to be flooded.
As climate change proceeds, cloudbursts and heavy downpours are likely to grow ever more frequent, and urban flooding is likely to become a more frequent, widespread and destructive challenge.
It will not go away by ignoring it. India has to plan how to stay dry in a wetter future.
The modern economy cannot afford to shut down because it rained or because it did not for a long period.
The short point is, floodproofing cities is not just about sparing their denizens occasional bouts of extreme inconvenience but also sustaining economic vibrancy of the city in question and of the country in general.
