Najafgarh drain bird sanctuary
Najafgarh drain bird sanctuary (proposed) and wetland ecosystem is composed of the wetland ecosystem and wildlife habitat on several kilometres of the Najafgarh drain or nullah which passes through rural southwest Delhi in India's capital territory. It includes the portion draining the depression or basin area that formed the once famous but now completely drained Najafgarh lake or Najafgarh jheel. Within the National Capital Territory of Delhi (NCT) this water-way, which is misclassified and misnamed as a mere drain (Najafgarh drain or nullah) is, in fact, the continuation of Sahibi River and an elongation of the Najafgarh jheel Lake. It is a tributary to River Yamuna in which it outfalls here. It becomes a refuge to thousands of migratory waterbirds every winter. The winter months are the best time to visit it to see many flocks of wintering waterbirds. It is currently classified as a Protected Forest and Recorded Forest (Notified Forest Areas in Delhi) as "M. P. Green area Najafgarh Drain (Tagore garden)", "Afforestation M.P.Green Area Najafgarh Drain (DDA)" and "Chhawla or Najafgarh drain city forest (29.64 Acre)".The wetland ecosystem and wildlife habitat on several kilometres of less polluted Najafgarh drain in rural Delhi before entering the main city, including the former Najafgarh lake or Najafgarh jheel area, is very important habitat to migratory waterbirds as well as local wildlife. It has been earmarked to be declared a bird sanctuary for Delhi. The area came to be recognised as an important wildlife habitat after a local naturalist studying the area during 1986 to 1989 called attention to it, recommending it to be conserved as a bird sanctuary. After this, the Delhi wildlife department posted 16 guards in the area to control illegal bird hunters, including diplomats from various international embassies located in Delhi, India's capital. Delhi Administration officials were tasked with declaring about 25 km stretch of the drain in rural Delhi, including where it passes through the core area of the now drained Najafgarh Lake or jheel, protected under the Wildlife Act after Lt. Governor of Delhi Mr. H.L. Kapur was invited to the area for touring the site where he also heard accounts of local villagers about the rampant illegal hunting of waterbirds that went on here every year. The existing staff of the Flood Control and Irrigation Department, numbering about 40, were also given the additional responsibility of protecting the wildlife on and around the drain.The Najafgarh drain has been much widened over the years to drain all the water which in earlier decades used to collect in the Nagafgarh lake or Jheel basin. This was supposedly done to remove the threat of flooding in Delhi, and now the drain itself acts as an elongated water body or lake. It has trees planted on both its embankments and an inspection road running on one embankment. During the winter months it attracts vast quantities of migratory birds, and supports local wildlife year-round. Due to the rich wildlife observed in and around the less polluted stretch of the drain outside of congested populated areas, it has been proposed as a bird sanctuary for Delhi.The Delhi Tourism and Transport Development Corporation has proposed the development of a bird sanctuary on the Najafgarh Drain. The sanctuary would cover an area of several kilometres along the Najafgarh drain and has advised to plant a large number of trees on both its embankments to form a thick forest belt. The Indian National Trust for Art and Cultural Heritage (INTACH) had been appointed as a consultant for the project. INTACH has been doing macro water harvesting since 1995 and has helped in creating a bird sanctuary on an 11-km stretch of water body that formed the Najafgarh Nallah (Drain). The 51 km-long Najafgarh drain starts at Dhansa and joins the Yamuna river near Wazirabad. 30 kilometres of the drain is in rural Delhi. With the help of the Irrigation and Flood Control Department of the Delhi Government, the drain was de-silted to increase its storage capacity. Regulators at Kakraula and Dhansa retain the water. Presently the brackish water is improving with dilution. By retaining the water in the drain, the aquifers and groundwater table have been recharged and there is more water now for irrigation, enabling farmers 6 kilometres away from the drain to grow crops. Tube wells in the area have been discharging water copiously and in two years the water table is up by a meter.A July 2003 report by the Central Pollution Control Board, Ministry of Environment and Forests of India pointed out: Bio-Monitoring of Wetlands in Wild Life Habitats of Birds Sanctuaries in India – Case Studies Wetlands of Najafgarh Drain, Chhawla, Delhi Delhi Tourism Department, Government of India, had identified this site for Chhawla Water World and Ecopark development. However, recently the site has been protected for development of Bird Sanctuary. A number of birds have been observed at the upstream location of Najafgarh drain from Chhawla up to Dhansa regulator. The water level is maintained by the Irrigation and Flood Control, Dept. of Delhi Government. Chhawla is located on Bijwasan-Najafgarh Road at about 10 kilometer from Gurgaon NH-8 on Rajokri crossing. Najafgarh drain receives waste water from Mundella Drain joining upstream of Chhawla at Kanganheri. Najafgarh drain originates as Dhansa outfall channel from Dhansa regulator located in Dhansa village in South-West of NCT-Delhi near Gurgaon border. Due to storage of water at Dhansa, the water body is stagnant at off take point. The catchment area of Dhansa Regulator/Bund obtains fresh water from drain coming from Jahazgarh Jheel, Sahibi Nadi and Catchment area lying in Lohat and Mundakhera in Gurgaon. Dhansa outfall channel terminates into Najafgarh Jheel. The catchment area of Najafgarh Jheel spreads in Delhi-Gurgaon border located 1–2 km distance from Jhatikra. Najafgarh Jheel is the largest surface water body in Delhi, spread over in an area of 6 km. This natural depression obtains fresh water from west of ridge, north of Karnal and from the catchment area lying in Gurgaon. Najafgarh channel was dug out from the Najafgarh Jheel during the year 1938 joining to the River Yamuna at downstream of Wazirabad barrage. The water quality of Najafgarh drain up to Chhawla supports wide range of aquatic fauna and flora including birds, fishes etc. The water is used for irrigation by direct pumping into adjacent cultivated lands of wheat, vegetables etc. MCD tube well adjacent to Najafgarh drain is used for drinking purpose by BSF colonies. Up to Kakraula regulator, Najafgarh drain receives several outfalls from sewage treatment plant. Najafgarh Drain is canalized after Bharat Nagar up to confluence to River Yamuna at Downstream Wazirabad Barrage.
