What is riverbank erosion and how does it affect Bangladesh?
0 views
Riverbank erosion is a major natural hazard in Bangladesh, where rivers constantly change course and erode banks. Every year, thousands of people lose their homes and farmland to erosion, particularly along the Jamuna, Padma, and Meghna rivers. Erosion displaces families, destroys infrastructure, and creates a class of "erosion refugees" who often migrate to urban slums. The government builds embankments and uses geo-bags to slow erosion, but the scale of the problem is enormous. Affected families can seek assistance through local government offices.
