Chilika is the largest brackish water lake in Asia and also the second largest lake in the world. Chilika is situated between 19º28' and 19º54' North latitude and 85º05' and 85º 38' East longitude. A mix of estuarine, marine and freshwater ecosystem is observed here and the lagoon has a long history of sustainable fishing. According to the Directorate of Fisheries Statistics 2000-01, the wetland supports 122,339 fisher folk who live in the 137 villages near Chilika.

Based on highly productive ecosystem, rich biodiversity and socio-economic importance, Chilika was designated as a Ramsar site in 1981. It has also found its position in the list of wetlands selected for intensive conservation and management by the Ministry of Environment and Forests (MOEF), Government of India. The Nalaban Island within the lagoon is notified as a "bird sanctuary" under Wild Life (protection) Act in 1987. Some rare, vulnerable and endangered animal species listed in the IUCN (International Union of Conservation of Nature and Natural Resources) inhabit the lagoon area for the whole or at least part of their life cycle.

It supports the largest congregation of aquatic birds in the country, particularly during the winter. Satapada is a place in this wetland, which hosts famous dolphins. The lagoon has a great value in preserving genetic diversity because of the variety of habitats, flora and fauna. In addition to its importance for water birds and biodiversity in general, significant numbers of people are dependent upon the lake's resource.

Due to serious degradation brought mainly by siltation and choking of the seawater inlet channel, the decrease in fish productivity, and an overall loss of biodiversity, Chilika Lake was added to the list of Ramsar sites in danger- the Montreux Record in 1993. To address the ecological problems of the lagoon, Chilika Development Authority (CDA) was created in 1992. It implemented a bold programme of action to restore the ecosystem and to improve the socio-economic conditions of the communities living around the lagoon and on its islands. The lagoon was later on removed from the Montreux Record in 2002 after a detailed survey by the Ramsar advisory mission.

The ecological problems in the Chilika lagoon exist till today. The threats are:

  1. Siltation due to littoral drift and sediments from the inland river systems.
  2. Shrinkage of water surface area.
  3. Choking of the inlet channel as well as shifting of the mouth connecting to the sea.
  4. Decrease in salinity and fishery resources.
  5. Proliferation of fresh water invasive species an overall loss of biodiversity with decline in productivity adversely affecting the livelihood of the community that depended on it.
  6. Fights between fishermen and non-fishermen communities about fishing rights in the lake and consequent court cases.
In early nineties the lake was 914 sq km in area, now it is less than 800 sq km. The major threat comes from the fight between the traditional and non-traditional fishermen. The non-fishermen community uses the unsustainable methods of shrimp farming to exploit the lake’s resources.
NGOs and concerned people in this area have come together several times to save the rights of the fishermen community. Public Interest litigations were filed and protest marches were made.  A proper decision is yet to be made by the state government on this issue.
