SERVIR-Himalaya Small Grant Programme

Web-based Landslide Early Warning System for the Chittagong Metropolitan Area (CMA)

Chittagong Metropolitan Area (CMA) lies in the hilly region of Bangladesh and experiences uneven rainfall patterns. According to local experts in Bangladesh, some of the factors that have aggravated landslide vulnerability in the area are rapid urbanization, increased population density, improper land use, and indiscriminate deforestation and agricultural practices. 

To help address this problem, BUET-Japan Institute of Disaster Prevention and Urban Safety (BUET-JIDPUS), Bangladesh University of Engineering and Technology is developing a web-based landslide early warning system for communities at risk in the Chittagong Metropolitan Area. 

The web-based early warning system will incorporate local knowledge and practices in landslide hazard management and planning. The system will be made available to the hill communities of CMA. It will identify user groups and their needs, incorporate local and expert knowledge in decision making, and disseminate early warning to the end users to help minimize damage.

The BUET-JIDPUS project will use a SERVIR-Himalaya grant to study the relationship between land cover change, rainfall, and climate change and landslide disaster, as well as human adaptation to landslide risks amid rapid urbanization and torrential rainfall. Community needs will be assessed to ensure effective implementation of the early warning system. The project will produce a landslide susceptibility map and create a web-based dynamic model to generate early warning for people living in the landslide vulnerable zones of CMA.

Various interactive sessions such as poster presentations, leaflet distribution, training and workshops will be organized during the project implementation. The project will hold meetings with concerned authorities and focus group discussions with vulnerable communities. Stakeholders will also be trained in the use of the web-based early warning system.
