- The National Green Tribunal has sought action- taken report from the Delhi and Haryana State governments over the declaration of Najafgarh as a wetland. Wetlands are formed where the water table is at or near the surface of the land, or where the land is covered by water.
- The directions came following a plea moved by an NGO, Indian National Trust for Art and Culture Heritage. The plea has claimed that despite the assurance of Haryana government that it would declare Najafgarh as a wetland, no steps have been taken to check encroachments. The government has also been alleged of planning to construct a check dam near Najafgarh lake to reclaim lands belonging to farmers.
- Najafgarh is an ecologically significant area as: a) serves as a habitat for several plant species and bird species such as Greater flamingos, sarus cranes and greater white pelican, b) acts as a major groundwater recharge zone for Delhi and Gurgaon, c) it is the only outlet for floodwater from Gurgaon. Environmentalists have raised concerns about the construction of the check-dam as it would destroy the ecology of the area.
