The community of Grande Riviere in Trinidad and Tobago was the subject of a multidisciplinary
study that employed a combination of geomatics, i.e., the use of field surveys and Geographic
Information Systems (GIS), and socio-economic data to evaluate the susceptibility of the
community to floods and storm surges due to sea-level rise. An examination was made of the
level of risk that the critical facilities and properties in the community could face in the future by
using projections of sea-level rise presented via spatial GIS models. Micro-data on socioeconomic
characteristics of the community was collected through a face-to-face administered
questionnaire. The results of this study may have important policy implications since policy- and
decision makers will have to act to reduce and/or eliminate risk of exposure of specific areas of
the community by implementing adaptation or mitigation measures and directing development
away from future high-risk areas.
