Why did the NGT deem the August 2026 deadline unreasonable for Yamuna floodplain demarcation?

The NGT found the August 2026 timeline unreasonable because similar demarcation exercises in other states were completed more expeditiously after receiving data from the Survey of India.

When is the physical demarcation of the Yamuna floodplain expected to begin?

Physical demarcation has not yet commenced; a tender has been floated, and the exercise will begin once the floodplain map is finalized.

Yamuna Floodplain: NGT Rejects August 2026 Deadline

The National Green Tribunal (NGT) has mandated the Delhi government to accelerate the demarcation of the Yamuna River's floodplain across a 22-kilometer stretch from Wazirabad to Palla. The NGT found the proposed completion timeline of August 2026 to be unreasonable, especially after receiving data from the Survey of India. The tribunal has directed the government to re-examine its action plan and submit a new report within two weeks with a shorter, feasible timeline.

Physical demarcation of the floodplain has not yet commenced, with the Delhi Development Authority (DDA) having only floated a tender. The NGT is hearing two cases based on recent news reports highlighting the long-standing delays in this crucial exercise. Previous NGT orders emphasized demarcation using the 1:100-year flood level and 1-meter contour mapping, a method applied to other rivers like the Ganga.
