Abstract
Fragile ecosystems and the harnessing of resources for human use are two major
elements that have to coexist in coastal regions. The sensitivity of the coastal
environment to oil spills and related cleanups depends on the presence of these
resources, and can be assessed by the level of potential impact that would be
caused by an oil spill. In this study, the Environmental Sensitivity Index (ESI)
and maps associated with it (ESI maps) are introduced and will be applied to the
Taiwan coastline. The ESI indicators include shoreline classification, biological
resources and resources for human use (socio-economic resources).
These indicators will represent the extent to which a specific coastal area
would be vulnerable to the effects of an oil spill. In other words, these indicators
tell us the level of reactions induced as a result of the adverse changes in safety,
survival and reproduction in ecosystems.
A framework for an index setup procedure will be described and constructed
in this study. ESI maps are very useful tools as complementary guidelines for
decision-making support systems in oil-spill contingency plans. Furthermore,
electronic ESI maps combined with a query scheme in a geographic information
system could be convenient to apply and use.
Keywords: oil spills, environmental sensitivity index (ESI), ESI maps,
geographic information system (GIS).
