It also one of the most threatened pieces of land in the world as a result of rising sea levels, due to climate change.
The eastern part of the island is witnessing rapid river bank erosion due to strong tidal flow of the Meghna as well as inclement weather in the Bay of Bengal.
The island is marked as one of the most vulnerable areas for natural disasters and is regularly pummeled by cyclones in the northern Bay of Bengal ocean.
The nearest ferry terminal is Kacchapiya Ghat, about 35 kilometres (22 miles) away in southern Char Fasson.
Despite the resident population occupying only a fraction of the land area towards the northern tip of the island, Dhal Char is home to approximately 13,000 people.
