The amendment to the River Ganga Authorities Order is a significant regulatory change by a statutory body that directly impacts environmental governance, disaster management in flood-prone areas, and the management of critical natural resources.

Notes

  • The Union government amended the River Ganga (Rejuvenation, Protection and Management) Authorities Order, 2016, via an August 10 gazette order from the National Mission for Clean Ganga (NMCG).
  • The amendment removes the blanket 'construction-free zone' clause that previously applied to the entire Ganga flood plain.
  • The new regulation replaces the total ban with an approval-based system for construction in specific zones.
  • The flood plain is now stratified into three zones based on flood frequency: Active flood plain (submerges at least once every 5 years), Regulatory zone (floods every 5-25 years), and Warning zone (floods every 25-100 years).
  • Construction is strictly prohibited in the 'active flood plain', with minor exceptions for temporary setups like religious events.
  • Construction is now permissible in the 'regulatory' and 'warning' zones, subject to official clearances.
  • The government states the change aims to correct legal inconsistencies rather than dilute environmental standards.
