New Delhi, March 29 (NationPress) The National Green Tribunal (NGT) has mandated that the authorities in Delhi undertake the demarcation of the Yamuna floodplain along a 22-kilometer stretch from Wazirabad to Palla, adhering to statutory regulations. The Tribunal emphasized that artificial embankments cannot be used to define floodplain boundaries.
A Bench led by Chairperson Justice Prakash Shrivastava, along with Expert Members Dr. A. Senthil Vel and Dr. Afroz Ahmad, was deliberating on several matters, including a suo motu case regarding floodplain demarcation and encroachments along the Yamuna.
The green tribunal acknowledged a status report submitted by the Delhi government, indicating that a draft floodplain map had been created using GIS technology based on one-meter contour data and flood boundary maps. This report noted that the draft map was shared with the Delhi Development Authority (DDA) for physical demarcation, which includes verification and the placement of boundary markers.
The report also mentioned that the ground-truthing process and the installation of bollards are expected to be finalized by July 31, 2026. “GSDL has prepared a draft PDF map through a lab-based GIS exercise using the one-meter contour data… which has been sent to DDA for ground-level demarcation,” the report detailed.
Additionally, it revealed that continuous efforts are being made to remove encroachments, with 1,426.6 acres of floodplain land reclaimed from May 2022 to February 2026. “Encroachments are being systematically removed from the floodplain, and possession has been taken over by DDA,” the report confirmed.
The NGT also reviewed a proposal from the Irrigation and Flood Control Department to construct a flood wall from Majnu Ka Tila to Nigam Bodh Ghat to mitigate floodwater ingress. However, the Bench led by Justice Shrivastava clarified that such structures cannot determine the extent of the floodplain.
“The demarcation of the floodplain must be conducted according to Clause 3 (l) of the River Ganga (Rejuvenation, Protection and Management) Authorities Order, 2016, and artificially created embankments cannot serve as the outer limit for floodplain definition,” the NGT stated.
The Tribunal recorded DDA's commitment to complete the demarcation process within the specified timeline and instructed both the Delhi government and DDA to submit further progress reports. “The responsibility for demarcating the floodplain over the aforementioned 22 km stretch lies with DDA, and this task will be finalized by 31.07.2026,” the DDA's counsel stated.
This matter is scheduled for a follow-up hearing on July 16, 2026, and the NGT has mandated that the progress report be filed at least one week prior to the next hearing date.
Point of View
The Tribunal emphasizes the importance of adhering to established statutory guidelines, ensuring both environmental protection and urban resilience.
