Large sections of mangrove forest on Sonadia Island are being cleared for shrimp farming and salt production [1, 2].
This loss of vegetation removes the natural barrier that protects the coast from erosion and storms. The destruction also threatens the local fisheries and wildlife habitats that the island's economy and ecology depend upon [1, 2].
Environmentalists and conservationists said the land is being cleared to expand industrial shrimp farms and salt-production facilities [1, 2]. These activities replace the complex root systems of mangroves, which traditionally serve as nurseries for various fish species and a shield against the sea [1, 2].
Local residents said they have observed a decline in fish catches as the mangroves disappear [1, 2]. Because the forests support the biodiversity of the region, their removal creates a ripple effect that impacts both the food security of the community and the survival of native wildlife [1, 2].
Conservationists said the removal of these forests leaves the coastline vulnerable to the elements, a significant risk in a region prone to tropical storms [1, 2]. The shift toward industrial salt and shrimp production prioritizes short-term commercial gain over long-term ecological stability [1, 2].
Efforts to protect the remaining mangroves are ongoing, but the expansion of these commercial interests continues to pressure the island's remaining green belts [1, 2].

The deforestation of Sonadia Island reflects a broader tension between industrial aquaculture and environmental preservation. By replacing mangroves with salt pans and shrimp ponds, the region loses its primary defense against storm surges and sea-level rise, potentially leading to permanent land loss and the collapse of artisanal fishing economies.
