Under the context of climate change adaption research, vulnerability assessment should take into consideration
the interaction among natural processes, socio-economic conditions, and the mechanisms of
response of the integrated ecological economic system. Pressure from urban development, land use and
land cover change along the western coast of Taiwan not only has caused the loss of ecosystem services in
peri-urban environments, but has also resulted in an increase in urban flooding vulnerability. This paper
develops a framework, which incorporates the interaction among exposure, sensitivity, and adaptive
capacity for assessing the vulnerability to flooding. To achieve this aim, this research interprets urban
flooding vulnerability based on emergy concepts and develops emergy indices to assess the spatiality
of urban flooding vulnerability in Taiwan’s western coastal plain via GIS. Based on the results of the
emergy evaluation of the three components of vulnerability and five emergy indices for urban flooding
vulnerability, the areas with intense urbanization are characterized with high potential impact to flood.
However, cities with higher potential impact do not necessarily lead to higher vulnerability for urban
flooding because adaptive capacity can also mitigate the vulnerability of cities to extreme climate events.
Using the framework developed by this research we show that the emergy concept can effectively provide
a common measuring unit for evaluating exposure, sensitivity and adaptive capacity of urban flooding
vulnerability.
