Abstract: | There is an increasing concern that the current management practices for many coastal regions are unsustainable. Very few
countries have planned to deal with the exacerbation of environmental decline in the face of sea level rise. It is therefore
necessary to assess socioeconomic and environmental impacts of sea level rises to better understand the vulnerability of coastal
zones, as part of devising adaptive and integrated management principles. This paper presents a systematic approach by which
relevant stakeholders can be actively engaged in prioritising flood impact issues and deriving information for quantification
of impacts for adaptation measures and demonstrates the approach through implementation in the Gippsland coastal region. As
outcomes of the project, we have identified key issues of concern for this region for flood impacts and constructed synthetic
response functions for quantification of impacts of floods on some of the key issues in the region. The analysis also showed
that stakeholders consider that some of the issues are not likely to be significantly affected by floods and thus may not
require adaptation measures. The analysis did not provide high agreement on some issues. Different approaches are required
to assess the importance of these issues and to establish impact response functions for them. |
