Geography of the Sundarbans

Location and Extent

The Sundarbans is situated in the delta formed by the confluence of three major rivers: the Ganges, Brahmaputra, and Meghna. 

It is bordered by the Bay of Bengal to the south. The forest consists of a complex network of tidal waterways, mudflats, and islands covered by salt-tolerant mangrove trees.

From above, it makes it look like an incredible network of veins flowing through the land. 

Mangrove Ecosystem

The Sundarbans is characterised by a unique mangrove ecosystem, which is extremely important to the surrounding area. 

This mangrove ecosystem provides the following:

  • Protection: A natural barrier against coastal erosion, cyclones, and tsunamis.
  • Biodiversity: A habitat for over 400 species of wildlife, including mammals, birds, reptiles, and aquatic life.
  • Climate Change: Mangroves play a significant role in mitigating climate change by absorbing large amounts of carbon dioxide.

The Sundarbans History 

Ancient History

The Sundarbans has been inhabited for thousands of years, with archaeological evidence suggesting human activity as far back as the Maurya (322-185 BCE) and Gupta (320-550 CE) periods.

The forest has historically been a source of livelihood, providing timber, honey, and fish to local communities.

Colonial Era

During British rule (1757-1947), the Sundarbans was commercially exploited for timber and other resources. 

This period also saw the establishment of forest management systems that laid the groundwork for modern conservation efforts.

The Sundarbans Today

The Sundarbans supports millions of people, directly and indirectly, through fishing, honey collection, agriculture, and tourism. 

It’s a truly incredible spot to visit - we explore more on tourism in the Sundarbans below. 

Future of the Sundarbans

The Sundarbans faces a critical juncture. 

While its ecological and economic importance is undeniable, the pressures of climate change and human activity mean urgent action is required. 

It is hoped that both Bangladesh and India strengthen their conservation efforts and promote sustainable livelihoods in order to preserve this unique land. 


Conservation of the Sundarbans

Protected Areas

In Bangladesh, key protected areas include Sundarbans East, West, and South Wildlife Sanctuaries. 

It also includes the Sundarbans Reserved Forest. This is managed under strict regulations.

Threats

The Sundarbans are under constant threat. Rising sea levels and increased salinity threaten the plants, and overexploitation of resources and industrial activities pose significant risks to the ecology.

Human-wildlife conflict is also an issue, with tigers and crocodiles occasionally coming into conflict with local communities.

Natural disasters pose a significant challenge to the area, as regular cyclonic storms cause extensive damage to both human settlements and wildlife habitats.

Conservation efforts are overseen by the Bangladesh Forest Department and international collaboration with UNESCO, IUCN, and NGOs.

Tourism

The Sundarbans is a major tourist destination, known for its stunning natural beauty and wildlife.
