Kanwar Lake, Asia's largest freshwater oxbow lake, in Begusarai district has been reduced to a vanishing wetland ecosystem as a result of encroachments, coupled with government inaction to save the natural aquifer. The lake was declared a protected area in 1986 by the Bihar government under the Wildlife (Protection) Act of 1972, which prohibited poaching, agricultural, industrial or any other activity in the area. In 1989, the Union government declared the wetland a bird sanctuary. An extensive study on the wetland in 2012 by Ashok Ghosh, a scientist and chairman of the Bihar State Pollution Control Board, found that the lake had covered 6,786 hectares in 1984, but by 2012, it had shrunk to 2,032 hectares. Alarmingly, in 2018, the lake area was deemed to be a mere 89 hectares. Ghosh attributes the shrinking wetland to encroachments by farmers who have built shanties and houses as well as to land sharks engaging in construction activities. The biggest casualty of the encroachment is the local fisherfolk Sahnis whose livelihood is at stake. They are at loggerheads with the farmers who want to practise agriculture on most of the land area of the lake. They also want the area to be developed as Krishi Evam Pakshi Vihar. Further, administrative apathy combined with eventual degradation of land and pollution has also impacted fishery activities. However, in a welcome change, in October 2020, Kanwar Lake was designated as a Wetland of International Importance under the Ramsar Convention, an international treaty for conservation and sustainable use of wetlands, making it the first Ramsar site in Bihar. This was applauded as a much needed step to protect the wetlands and minimise conflicts in the area.
