The Delhi Development Authority (DDA) has commenced a drone survey to identify the O-zone land along the Yamuna River, a crucial area designated for environmental protection under the Delhi Master Plan 2021. This survey, expected to take about two months, is part of a phase 2 initiative aimed at combating illegal encroachments in the floodplain area where construction is strictly prohibited. In a recent report to the National Green Tribunal (NGT), the DDA indicated that encroachment removal drives had successfully cleared seven acres of land on April 16 and 17, particularly around Madanpur Khadar and Jhangola village. The DDA has digitized the O-zone boundary based on approved planning documents and land records, and the drone operations began on February 5. The DDA is also working closely with the Municipal Corporation of Delhi (MCD) to prevent future encroachments and has directed police to maintain vigilance against unauthorized constructions. The ongoing efforts reflect a commitment to preserving the Yamuna's floodplain and ensuring compliance with environmental regulations.
