An evaluation and monetary assessment of the impact of flooding on subjective well-being across genders in Vietnam
The intangible impacts of floods on welfare are not well investigated, even though they are important
aspects of welfare. Moreover, flooding has gender based impacts on welfare. These differing impacts
create a gender based flood risk resilience gap. We study the intangible impacts of flood risk on the
subjective well-being of residents in central Vietnam. The measurement of intangible impacts through
subjective well-being is a growing field within flood risk research. We find an initial drop in welfare
through subjective well-being across genders when a flood is experienced. Male respondents tended
to recover their welfare losses by around 80% within 5 years while female respondents were associated
with a welfare recovery of around 70%. A monetization of the impacts floods have on an individual’s
subjective well-being shows that for the average female respondent, between 41% to 86% of annual
income would be required to compensate subjective well-being losses after 5 years of experiencing a
flood. The corresponding value for males is 30% to 57% of annual income. This shows that the
intangible impacts of flood risk are important (across genders) and need to be integrated into flood (or
climate) risk assessments to develop more socially appropriate risk management strategies.
