“Areas of marsh, fen, peat land or water, whether natural or artificial, permanent or temporary, with water that is static or flowing, fresh, brackish or salt, including areas marine water the depth of which at low tides does not exceed six meters”
More than two thirds of the country's landmass may be classified as wetlands according to this definition given by Ramsar Convention (IUCN,2005)
The total area of wetland in Bangladesh has been estimated to be 7-8 million hectares which is nearly 50% of the countries landmass.
But Chowdhury et al (1996) showed that, total wetland of Bangladesh cover about 11% of the total area which is 16,000 square km.

Wetlands act as water purifier as it traps and filters the water that moves through it.
Slows down surface runoff.Reduce flooding and siltation of rivers.Reduce the action of toxic chemicals by
nutralizing them.Help replenish underground water reservoirs.
Habitat for plants and animals, migratory and resident water fowls & the significant endangered species.
Total number of vascular plants is 123 ( excluding trees and mangrove species)
Including swamp forest trees it becomes 157.
Wetland plants provide
Firewood, Thatching materialMedicinal plantsLivestock fodderFood source for humans
Rice, jute, wheat, potato, cucumber, watermelon, tobacco etc are the common crops of haor and floodplain areas.

Bangladesh Perspective
a. natural water bodies such as beels, haors, and baors will be preserved for maintaining the aquatic environment and facilitating drainage.
b. only those water related projects will be taken up for execution that will not interfere with the aquatic characteristics of those water bodies.
c. haors that naturally dry up during the winter will be developed for dry season agriculture.
d. take up integrated projects in those water bodies for increasing fish production.
e. natural water bodies will be developed, where possible, for recreational use in support of tourism.

Incorporating vulnerable women and men in these committees
Community people of 8 villages donated their lands for building ‘Wetland Management and Training Centre’

Participatory plantation Rehabilitating aquatic habitatsConservation of threatened wildlifeMedical Plant Conservation
Plantation along re-excavated canals or beels450,000 saplings of swamp forest species have
been planted covering an area of 500 acres/200 hectares in the project sites
Establishment of conservation area:250 ha area of Hakaluki haor has been protected to
accelerate natural succession of wetland flora and fauna
After 2 years, successful succession of hizal, karoch, bantulshi, gujja kanta, asparagus, nall, khagra etc have been ovserved
Large fauna like mongoose, fishing cat, snakes, frogs etc are found to be increasing in number
Reintroduction of locally extinct species:More than 150 thousand hatchlings and
fingerlings of the following species have been introduced in selected sites
PabdaHeronpuntiSarpuntiLocal magurRuiMrigel
Fish conservationDeveloping fish conservation areas20 fish sanctuaries in 5 sitesNo fishing for stipulated time
Fresh water turtle conservation2 hatcheries & some conservation areas150 hatchlings have been released in natural wetlands
Action plan to organize eco-tours which includes:
Construction of a dolphin watchtowerTurtle rearing in shrine pondsRudimentary natural history museum in schoolsRiver biodiversity watch-hutIchhamati riverine trailDeciduous forest trails
Village groups, village environment committee and village resource management committee have been provided a total amount of tk. 5.5 million.
Some groups have shown real success by doubling or making large profit from the seed money.
BEFORE: Hail Haor wetlands in 1999. Over the last 150 years, approximately 50 percent of dry season wetlands have disappeared, resulting in lower fish production. Environmental changes, such as flood embankments and large silt deposits have reduced the area and quality of Bangladesh’s water bodies.
AFTER: Hail Haor in 2006. This site has been restored to improve the flow of water and fish from larger rivers. Community management groups now control dry-season fishing. Native fish species have been reintroduced and local fishermen have seen their yields increase by over 150 percent, generating more than $10 million worth of fish in 2005 alone.Source:

BEFORE
AFTER
Prohibit wetland conversion by lawRestore and rehabilitate the degraded
wetlandsBring all significant wetlands under
sustainable management programLimit hunting & fishing to such an extent that
breeding & spawning of various species is not hindered
Carry out Environmental Impact Assessment before initiating any engineering project
