Sundarbans Wetlands and Ramsar Convention: 27th in India

 

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.

Biodegradable Golf Balls: Eco-friendly Solution for every Golfer

Did you know that every year thousands of golf balls are lost in our planet's waterways? This probably does not surprise anyone who plays golf. What harm could a little golf ball do anyways? Well, new studies are coming to light that the little golf ball is a big problem. As they break down they release their contents into the ecosystem. A modern golf ball is made from the following: thermoplastics, zinc oxide, zinc acrylate, benzoyl peroxide, heavy metals, polybutadiene, and other secret combinations of exotic materials not disclosed by the manufacturer. These are not good for the planet! Don't forget about the plastic portion of the ball either. As it breaks down the plastic turns into microplastics. From the deepest depths of the ocean to the snow of the Artic microplastics have been found by pollution researchers to invade every corner of our planet. The size of the current microplastic pollution problem is huge! Estimates are between 15 trillion and 51 trillion microplasti...

Urban Sprawl: An Emerging Issue

  Humans are becoming an increasingly urban species. They want to move to metropolitan cities and urban centres for better jobs opportunities or for the excitement of the city life. And this possess a really challenging developmental question of where are all these people going to go and if you live in a city, you might have noticed the expansion and the development of cities to suburbs and this is what we call urban sprawl. In 1937, Earle Draper - one of the first city planners in the south-eastern United States coined the term ‘sprawl.’ The urban sprawl is essentially the geographical expansion of a city or town and is often characterised as low density development, meaning housing is being built on really large land areas or scattered land locks, single use zoning and is also characterised by the increased reliance on private automobiles for each person transportation. The sprawl generally takes place in radial course around the city centre or in linear direction along the highw...

Green Tax for a Greener Society

  Recently, Tesla has launched their electric cars in the Indian market. Though there has been a mixed reaction by the Indian consumers because of the price of the cars and lack of charging facilities. It is expected that Tesla will find it difficult to compete with the Diesel and Petrol variants as well as Indian electric car manufacturers. Talking about electric cars in order to curb environmental pollution and encourage people to switch to eco-friendly transportation mode, the Union Ministry for Road Transport and Highways of India has approved a proposal to levy a ‘Green Tax’ on old vehicles. Experts argues that, charging taxes on vehicles that cause environmental pollution will decrease environmental loss in a cost effective manner by encouraging behavioural changes among people. The Green Tax can be seen as a measure to strengthen India’s commitment to the Paris Agreement of 2015. As per the agreement India has targeted to reducing the emissions intensity of its GDP by 33...
