Bangladesh, known for its abundant natural water resources, is a country of deltaic plains with over 700 rivers and tributaries. Among these water bodies, the Feni River is one of the significant ones. The river is about 100 km long and flows through the southeastern part of Bangladesh, originating in the Indian state of Tripura, flowing through Sabroom in India, and eventually emptying into the Bay of Bengal near the Chittagong port.
Geographical Location and Characteristics
The Feni River originates from the hills of Tripura, India, and flows through the southern part of Tripura state before entering Bangladesh. It then flows through the districts of Khagrachhari and Chittagong before finally merging into the Bay of Bengal. The river is around 100 km long and is the only natural boundary between Bangladesh and India.
The river’s width varies from 100 to 200 meters, with an average depth of 10-15 meters. The river’s flow is typically slow, with a current velocity of around 1.5 m/s during the monsoon season and around 0.2 m/s in the dry season.

Threats to Feni River
Despite its ecological, economic, and cultural significance, the Feni River is facing various threats that could affect its health and sustainability. Some of the significant threats to the river include:
- Industrial Pollution: The region surrounding the Feni River has various industries, including tanneries, textile mills, and chemical factories. These industries discharge their effluent and waste into the river, leading to water pollution. The pollution not only affects the water quality but also impacts the aquatic life and other species dependent on the river.
- Deforestation: The region surrounding the Feni River has undergone significant deforestation, leading to soil erosion, sedimentation, and loss of biodiversity. The soil erosion and sedimentation have impacted the river’s flow, leading to flooding and other water-related disasters.
- Climate Change: Climate change has led to changes in rainfall patterns and weather conditions, leading to a decrease in the river’s water flow. The decrease in the river’s water flow has impacted the irrigation, fisheries, and transportation activities dependent on the river.
- Illegal Sand Mining: Illegal sand mining is another significant threat to the Feni River. Sand mining leads to the river’s bed’s erosion and alters the river’s flow, leading to flooding and other water-related disasters. Sand mining also impacts the river’s ecology, leading to the loss of aquatic species and another biodiversity.
Steps Taken to Protect Feni River
The government of Bangladesh has taken several measures to protect the Feni River and ensure its sustainability. Some of the significant steps taken include:
- Enforcement of Environmental Laws: The government has enforced environmental laws to control industrial pollution and other activities that could harm the river’s ecology. The government has also set up monitoring systems to check the water quality and take necessary actions to prevent pollution.
- Afforestation and Reforestation: The government has initiated afforestation and reforestation programs to increase the forest cover in the region. The programs aim to reduce soil erosion, improve water quality, and protect the river’s ecology.
- Awareness Campaigns: The government has launched various awareness campaigns to educate the local communities on the river’s significance and the need to protect it. The campaigns aim to change people’s behavior towards the river and create a sense of ownership among them.
