- Kurzbeschreibung<p>The frequent occurrence of disastrous floods results in losses for both human life and property values in Bangladesh. This study thus is set forth to examine the relationships between socioeconomic conditions and vulnerability to flood hazards. A cross sectional household survey was carried out two weeks after floods in four districts of Bangladesh in the year 2005. In total 1050 households in rural areas were interviewed through a three stage stratified random sampling. Among the four sampled districts, three were affected by monsoon floods and only one, the Nilphamari district, was affected by a flash flood. Bivariate analyses depict that floods have significant downside effects on households¿ wellbeing, as overall headcount poverty level deteriorates by 17 percent. The worst welfare loss is measured in Jamalpur district where the majority of households are involved with agriculture. A multivariate regression model is carried out that shows that some demographic, socioeconomic and community variables along with flood shock variables have a noteworthy impact on flooded and non-flooded households¿ income. Estimates of a multinomial logit model illustrate that flood height, duration and loss of working days are significant for the poor households¿ income deterioration, whereas non-poor households are significantly affected by flood duration and loss of assets during floods. To assess households¿ vulnerability to floods, this study incorporates four methodologies from the poverty dynamic literature. Vulnerability estimates from the `vulnerability to expected poverty¿ approach depict that flooded households have a higher risk of falling below the poverty line compared with the non-flooded households. This is the only methodology out of four used in this study that could estimate households¿ vulnerability from crosssectional data and thereby allowing to estimate non-flooded households¿ vulnerability. The results show that idiosyncratic vulnerability is higher for households affected by monsoon flood, whereas flash flood worsens households¿ covariate vulnerability. Households involved with agriculture are found to be more vulnerable than other income groups. The `vulnerability to expected utility¿ approach illustrates that elimination of poverty would increase household welfare and thus lessen vulnerability the most. Poverty and idiosyncratic flood risks are positively correlated and highly significant. Households with higher educated members, being male-headed and owner of a dwelling place have been found to be less vulnerable to idiosyncratic flood risks. Possession of arable land and a small family size can reduce poverty and the aggregate flood risk
