Mangroves in Kolkata: The Gateway to the Majestic Sundarbans

Mangroves in Kolkata: The Gateway to the Majestic Sundarbans

Kolkata, often referred to as the “City of Joy,” is also the northern gateway to the Sundarbans, the largest mangrove forest in the world.

Located at the mouth of the Ganga-Brahmaputra-Meghna delta, the mangroves in and around Kolkata play a vital role in protecting the city from natural disasters, supporting biodiversity, and combating climate change.

While the urban sprawl of Kolkata itself has limited mangrove cover, its proximity to the Sundarbans makes it a crucial hub for mangrove conservation efforts.

Historical and Cultural Significance

The Sundarbans, a UNESCO World Heritage Site, has been deeply intertwined with the culture and livelihood of communities in and around Kolkata for centuries.

The name "Sundarbans" derives from the Sundari tree (Heritiera fomes), a dominant species in the mangrove ecosystem.

Historically, the Sundarbans mangroves acted as natural barriers against tidal waves and storms, protecting the settlements of Kolkata and the surrounding areas. Over time, the forests have also been a source of fish, honey, and timber for local communities.

Ecological Importance

1. Flood and Cyclone Mitigation

Mangroves absorb the impact of tidal surges and cyclones, acting as Kolkata’s frontline defense against natural disasters. Events like Cyclone Amphan (2020) demonstrated the importance of these forests in reducing damage to urban and rural areas.

2. Carbon Sequestration

Mangroves store carbon at rates far exceeding most terrestrial forests. The Sundarbans mangroves play a critical role in offsetting greenhouse gas emissions and mitigating climate change effects for Kolkata and beyond.

3. Biodiversity Hotspot

The mangroves near Kolkata are home to a rich array of wildlife, including the elusive Royal Bengal tiger, saltwater crocodiles, and rare birds like the masked finfoot. This biodiversity not only supports the ecosystem but also attracts eco-tourists.

4. Supporting Livelihoods

For generations, local communities have relied on the mangroves for fishing, crab collection, and honey harvesting. These activities are intricately linked to the health of the mangrove ecosystems.

Fun Facts About Kolkata’s Mangroves

  • Tiger Tales: The Sundarbans mangroves are the only mangrove forest in the world to host a significant tiger population.
  • Sundari Trees: The Sundarbans are named after the Sundari tree, known for its high-quality timber and salt tolerance.
  • Natural Air Purifiers: The mangroves around Kolkata act as nature’s filtration system, improving air and water quality.

Environmental Challenges

  1. Urbanization and Deforestation The expansion of Kolkata and nearby towns has led to the clearing of mangroves, reducing their ability to protect against erosion and storms.

  2. Rising Sea Levels Climate change has caused an increase in sea levels, threatening to submerge parts of the Sundarbans and endangering its mangrove cover.

  3. Pollution Industrial waste, untreated sewage, and plastic pollution are significant threats to the health of mangrove ecosystems near Kolkata.

  4. Salinity Changes Increasing salinity due to rising seas impacts the growth and regeneration of mangroves, especially species like the Sundari tree.
