Key Facts

Name: Ganga-Brahmaputra Delta (Sundarbans).

Title: The Largest Delta in the world.

Rivers Involved: Ganga, Brahmaputra, and Meghna.

Location: West Bengal (India) and Bangladesh.

Apex Predator: The Royal Bengal Tiger.

UNESCO Status: It is a recognized UNESCO World Heritage Site.

Location and Formation

The Sundarbans Delta spans a massive area of over 100,000 square kilometers, situated in the Bengal region. It covers parts of West Bengal in India and the southern part of Bangladesh. It is formed by the confluence (joining) of three mighty rivers: The Ganga, The Brahmaputra, and The Meghna. As these massive rivers flow down from the Himalayas, they carry millions of tons of fertile silt, dumping it into the Bay of Bengal and creating this massive fan-shaped landmass.

Why is it called the Sundarbans?

The name 'Sundarbans' literally translates to 'Beautiful Forest' in Bengali. However, geographically, it is named after the Sundari tree (Heritiera fomes), a special type of mangrove tree that grows abundantly in the salty mudflats of this delta.

Ecological Importance: The Mangroves and Tigers

The Sundarbans is completely unique in the world.

  1. It contains the largest continuous mangrove forest on the planet. These mangrove roots hold the mud together and protect the inland areas from deadly cyclones and tsunamis originating in the Bay of Bengal.
  2. It is the only mangrove forest in the world that is home to a population of tigers—the legendary Royal Bengal Tiger. These tigers have uniquely adapted to an amphibious life, swimming easily between the mud islands.
