Bengaluru has been in the news lately. However, most of Indian cities are likely to experience urban flooding with various levels of severity. What are the reasons for this annual disaster? Can we still rescue our urban areas?
Every monsoon we hear about flooded streets of metro cities. Recently, smaller towns have also joined this sad list and we can not help, but ask ourselves why does urban flooding occur?
Clogged or dysfunctional drainage prevents rainwater from flowing freely
Construction on lake and river beds, complete disregard for natural flow of water
Cutting of trees in already stressed urban areas, concrete roads and absence of 'empty' spaces due to overpopulation
Dr. Madhavan Nair Rajeevan explains how Indian cities can prepare better for heavy rain events
Can we still try and reverse the damage? We can not change the rain pattern, but we can take an individual action to help mitigate urban flooding.
Before building/buying a house or apartment do a due diligence check and compare the old map of the place with the current one. If you see, that the land has been 'reclaimed' from a lake or river you are almost sure to experience urban flooding there.
