The Challenge of Urban Flooding

Research suggests that heavy rainfall events are on the rise. “The time has come to take serious cognisance of the link between climate change and extreme weather events like Chennai floods,” notes an essay from the Hans India. “As recommended by Centre for Science and Environment, India should start internalising climate change adaptation in all developmental policies and programmes.” Cities as heat centers with developed catchment areas are more prone to flooding than rural areas, the essay suggests. With costly infrastructure and greater numbers of people, cities are especially vulnerable to economic disruption. Torrential rains have hit Chennai, the capital of the southern Indian state of Tamil Nadu and home to more than 5 million people. The city confronts widespread power outages, forecasts of more rain, and closed schools and factories. Rather than deny or delay, cities must prepare and invest in new defenses. – YaleGlobal
