Study calls for urgent reforms to mitigate floods and droughts in Chennai
The HinduWhile a non-governmental organisation says that Chennai is prone to floods and droughts and demand urgent reforms and mitigation efforts, officials of the Greater Chennai Corporation contest such claims and point at the current water management initiatives. A recent study by Arappor Iyakkam, an NGO, identified significant issues in Chennai’s water management system, especially the Kosasthalaiyar, Cooum, and Adyar, and implied that the city is vulnerable to floods as well as droughts. Ill-prepared for the monsoon The study says, “Chennai is significantly ill-prepared for the upcoming monsoon” and there is an urgent need for comprehensive water management reforms by the State government — such as large-scale desilting of lakes and ponds, improving rainwater harvesting infrastructure, restoring waterbodies, and ensuring sewage treatment before discharge into waterways. The study stresses the need for a comprehensive water management policy and calls for strict measures to prevent solid and liquid waste disposal into waterbodies, improved rainfall forecasting, and the development of new climate models to predict extreme weather events. A Corporation expert in management of waterbodies says that besides the storm water drain projects, efforts include phased restoration of lakes, ponds, and canals, with wetland rehabilitation, and measures to protect low-lying areas.
