Social vulnerability analysis for sustainable disaster mitigation planning in coastal Bangladesh

Abstract

Purpose

The opportunities and potentials of the coastal zone all over the world have not received much attention, and also the disaster mitigation approaches are seen as a curative measure rather than protective, both of which raise questions about sustainable coastal belt planning and development. What is needed is a multidisciplinary approach to tackle the complexity of social systems, and patterns of vulnerability in those systems. The aim of this paper is to attempt to understand those challenges in context of cyclone SIDR 2007 in Bangladesh.

Design/methodology/approach

The combination of spatial and socio‐economic data in this study is based on an empirical analysis. After clustering the geographical boundary, a systematic random sampling technique was applied to identify the respondents for a household survey. A total of 47 percent of the respondents were illiterate and thus required the help of data collectors. In‐depth interviews were conducted with the victims of cyclone Sidr to ascertain their experiences during the event.

Findings

The heterogeneous characteristics of the respondents show that the impact of disasters varies from individual to individual, group to group and community to community. It is evident that an affected community waiting for relief and reconstruction materials attracts “dependency on relief works” which makes them more “vulnerable” to other calamities. In the long run it increases the poverty ratio and pressurizes them to stay in a “vulnerability trap” in any type of calamity. Furthermore, it reveals a socio‐infrastructural vulnerability and also the overall “social vulnerability” concepts by using a combination of socio‐spatial data.

Originality/value

This paper contains valuable information regarding the adaptation strategies to cyclone hazards resorted to by coastal peoples in Bangladesh.
