Landslide in Bangladesh is very common in the hilly areas of southeastern Bangladesh,
especially in Bandarban, Rangamati, Khagrachhari and Cox's Bazar. Every year
especially in the rainy season landslides take place in both natural and
man-induced slopes. The major roads connecting Bandarban town with the rest of
the country is affected by landslides almost every year isolating the town and
contiguous areas. Not only are roads but also a considerable number of
infrastructures are damaged and valuable lives lost. Landslides due to the
construction of buildings and other infrastructures have been mostly restricted
to the urban and semi-urban centres of hill districts. The effect of jhum cultivation
and other forms of cultivation on steep slopes also play a significant role in
the occurrence of landslide. Hill cutting is a major cause of landslide. Common
engineering techniques for landslide prevention include provision for surface
and subsurface drainage, removal of unstable slope materials, construction of
retaining walls, or some combination of these. Many of them are currently used
in Bangladesh. A successful integrated bioengineering and drainage control
approach (Geo-Jute Textile method) for landslide protection and mitigation was
carried out at Bandarban.
