Abstract
Purpose: There are several urban areas close to the sea and other water bodies that may be adversely affected by erosion and flooding. Global climate change, including sea-level rise and more intense and damaging storms, will increase the threats of natural hazards in several areas. Mitigating and adapting to these risks in urban areas are huge challenges for society. There is a need for a proper decision basis to build a society that is economically, socially, and environmentally sustainable. By incorporating coastal hazard and risk mapping into spatial planning, new developments can be diverted away from threatened areas. Further, by taking adaptation measures, risks in existing urban areas can be reduced. The purpose of this paper is to address these issues. Design/methodology/approach: This paper presents the results of two case studies and discusses the prerequisites for impact assessment and project appraisal and how this is used and accepted by the users and decision-makers. Findings: A guideline has been developed as a tool for the integration of costs and benefits in decision making on investments in coastal zones. The guideline gives an overview of why, when, and how impact assessments and project appraisals can be made using socio-economic valuations of coastal areas affected by erosion. Two case studies have been performed to demonstrate the practical application of the guideline and economic analysis and valuation in coastal management. Originality/value: The guideline can be used to prioritise areas that need attention due to threatened shorelines, and to decide which preventive measures are the most efficient from a socio-economic point of view.

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
