Resumen:
In this paper, an adapted methodology to evaluate coastal erosion
vulnerability, which provides a basis for decision-making concerning
risk management strategies, is described. The vulnerability evaluation
was based on weighted indicators and assessed the vulnerability under
different climate change scenarios. To generate the vulnerability index,
dynamic processes, geo-indicators, and social and morphological
parameters associated with modeled scenarios of sea level rise and
predicted wave height changes were integrated. The study area included
the sandy beaches in Pernambuco, NE Brazil, and was used to describe the
practical application of this approach. Because the occupation of large
sectors of the coastline was low, the vulnerability was concentrated in
urbanized areas. The high-vulnerability sections of the coast were those
with high population densities, high-rise buildings, induced coastal
squeeze and hard engineering structures. The low-vulnerability beaches
generally had low urbanization rates and well-conserved, resilient
coastlines. Under future scenarios, the vulnerability of this coastal
region will increase with sea level rise and wave height changes.
