On
January 30, 2019 the Indian Sundarbans was accorded the status of Wetland of
International Importance under the Ramsar Convention. The Sundarbans comprises
of hundreds of Islands and a network of rivers, tributaries and creeks in the
delta of the Ganga and the Brahmaputra rivers at the mouth of the Bay of Bengal
of India and Bangladesh. Indian Sundarbans constitutes over 60% of the
country’s total mangrove forest area. It is the 27th Ramsar site in
India and the largest protected wetland in the country. Ten more site has been
accorded the status of Wetlland of Internattioal Importance (Read here).
About Ramsar Convention
The Convention on Wetlands of International
Importance, better known as the Ramsar Convention is an international agreement
promoting the conservation and wise use of wetlands. It is the only global treaty to focus on a single ecosystem. The
Convention was adopted in the Iranian city of Ramsar in 1971 and came into
force in 1975. Traditionally viewed
as a wasteland or breeding ground of disease, wetlands actually provide
freshwater and food and serve as nature’s shock absorber. Wetlands critical for
biodiversity are disappearing rapidly. With recent estimates showing that 64%
or more of the world’s wetlands have vanished since 1900. Major changes in the land use for agriculture and grazing, water
diversion for dams and canals and infrastructure development are considered to
be some of the main causes of loss and degradation of wetlands.
About Sundarbans
The
Indian Sundarbans met four of the nine criteria required for the status of
Ramsar convention:-
·
Presence of rare species and
threatened ecological communities, biological diversity, significant and
representative fish and fish spawning ground, migration path.
·
Indian Sundarbans is also a UNESCO world heritage site, is home to
the Royal Bengal Tiger, Northern river terrapin (Critically Endangered), Irrawaddy
Dolphin (Endangered), Fishing Cat (Vulnerable), Horse Shoe Crab and Kingfisher.
·
Indian Sundarbans is home to 2626
faunal species and 90% of the countries mangroves varieties
Importance of Ramsar Status
Environmentalists
and forest officials say that the Ramsar status will help to highlight the
conservation issues of the Sundarbans at the international level. The part of Sundarbans delta which
lies in Bangladesh was accorded the status of a Ramsar Site in 1992, and with
Indian Sundarbans getting it too international cooperation between the two
countries for the protection of this unique ecosystem will increase. This
could lead to a better conservation strategy for flagship species such as the
tiger and the Northern River terrapin.
Threats to the Sundarbans Wetland
While
the Indian Sundarbans is a biodiverse preserve, over four million people live
on its northern and north-western periphery, putting pressure on the ecosystem.
Concerns have been raised about natural ecosystems being changed for
cultivation of shrimp, crab, molluscs and fishes. The Ramsar information sheets
lists fishing and harvesting of aquatic resources as a “high impact” actual threat to the wetland. The other threat to the
wetland are dredging, oil and gas drilling, logging and wood harvesting,
hunting and collecting terrestrial. Salinity has been categorised as a “medium” and tourism as a “low” impact actual threat to the region.
Experts believe that while the Ramsar status may bring in international
recognition to the Indian Sundarbans, the wetland which along with
anthropogenic pressure is also vulnerable to climate change and requires better
management and conservation practices.
