In Chittagong city, landslide phenomena is the most burning issue which causes great problems to the life and properties and it is increasing day by day and becoming one of the main problems of city life. On 11 June 2007, a massive landslide happened in Chittagong City Corporation (CCC) area, a large number of foothill settlements and slums were demolished; more than 90 people died and huge resource destruction took place. It is therefore essential to analyze the landslide susceptibility for CCC area to prepare mitigation strategies as well as assessing the impacts of climate change. To assess community susceptibility of landslide hazard, a landslide susceptibility index map has been prepared using analytical hierarchy process (AHP) model based on geographic information system (GIS) and remote sensing (RS) and its susceptibility is analyzed through community vulnerability assessment tool (CVAT). The major findings of the research are 27% of total CCC area which is susceptible to landslide hazard and whereas 6.5 sq.km areas are found very highly susceptible. The landslide susceptible areas of CCC have also been analyzed in respect of physical, social, economic, environmental and critical facilities and it is found that the overall CCC area is highly susceptible to landslide hazard. So the findings of the research can be utilized to prioritize risk mitigation investments, measures to strengthen the emergency preparedness and response mechanisms for reducing the losses and damages due to future landslide events.

Chittagong city dwellers face the consequences of inadequately planned and managed urbanization as the city is unable to provide proper services and facilities to all classes of people. West Bakalia area is a deprived part of the Chittagong city located near the Karnafuli river. One of the main canals of the city ‘Chaktai khal’ and its branches passes through it. Questionnaire survey and focus group discussion are conducted to understand the nature of this problem. Multidimensional Poverty Index (MPI) method is used to identify the poverty level of the people in West Bakalia. Participatory Rural Approach (PRA) method is used to seek out the causes and effects of the poor’s socio-economic condition with cause-effect diagram tool, mobility pattern showing frequency, mode choice and destination of the respondents with mobility map, social institutions and resources of the area with social and resource map. They suffer from poor road surface condition, poor accessibility and safety issues too. Also, unavailability of healthcare center facility and recreational places has worsened the situation in the area with poor livable condition. The urban poor and their right to have livable condition must be accepted as an important factor and therefore included in the more appropriate planning framework for Chittagong city following the recommendations provided in this research.
