Following repeated instances of flooding in Mumbai and its adjoining areas, environmentalists have stressed the need to bring back the river rejuvenation policy in Maharashtra.  The state had scrapped the river rejuvenation policy in 2015, which elaborated on buffer zone around rivers and discharge of effluents.
Environmentalists have demanded a river regulation zone (RRZ) policy to check construction on floodplains and wetlands. “The construction boom on floodplains on the outskirts of Mumbai has disturbed the flow of various rivers during heavy rainfall, resulting in disasters,” said environment groups The Nature Connect and Shree Ekvira Aai Pratishtan (SEAP) in their letter to chief minister Devendra Fadnavis.
