Ganga Floodplain Laws Altered: Construction Fears Rise

An application challenging recent amendments to the River Ganga (Rejuvenation, Protection and Management) Authorities Order, 2016, is set for a hearing before the National Green Tribunal (NGT). The Union Ministry of Jal Shakti issued a gazette notification on August 10, 2026, altering key environmental protections for the Ganga's floodplain. These changes include the removal of the "construction-free zone" and a revised definition of "floodplain" to encompass only the area affected by a one-in-five-year flood, a significant reduction from the previous one-in-100-year parameter.

Environmental activist Dr. Amit Kumar has filed an urgent application with the NGT, arguing that these amendments are detrimental to the environmental health of the Ganga basin. He contends that the modifications dismantle crucial safeguards previously in place and are legally unsustainable. The petition highlights that the deletion of the mandatory "construction-free zone" and the redefining of active floodplains effectively permit construction in areas historically protected from development.

Dr. Kumar further expressed grave concern that the revised definitions open up extensive areas of the Ganga's flood buffers to commercial, industrial, and real estate development. He stated this dilution of environmental safeguards poses an existential threat to the sacred river, which is vital for over 500 million citizens. The Ministry of Jal Shakti, the National Mission for Clean Ganga, and the environment ministry are respondents in the case.
