EcosHaz project aims to establish a sustainable knowledge framework addressing the costs and benefits of prevention and response to coastal hazards resulting from hydro-meteorological events (flooding, shoreline erosion, storm surges, sea level rise) and oil spill accidents.

Coastal hazards are a major concern for local population and authorities since the interaction of coastal processes with human activities and structures can adversely affect the economy, health, well being and safety of people and communities. An effective hazard mitigation planning requires the cost-benefit assessment of the various risk prevention measures correlated to the costs for response and rehabilitation (SEC/2010/1626, COM/ 2011/934 etc).

Notwithstanding the considerable progress that has been made over the past few decades in the fields of hazards’ analysis and modelling, successful delivery of Cost/Benefit (C/B) assessment still remains very challenging. The considerable diversity of methodological approaches and terminology in use complicates the deduction of robust and comparable C/B figures. Besides the methodological differences, the lack of reliable publicly available cost assessment data is a major obstacle for process development. Existing cost databases are rather scarce, containing usually heterogeneous data or figures defined at an aggregate level. Moreover many parameters related to the coastal hazards’ impacts are hardly reflected resulting in considerable uncertainties during the evaluation process of the appropriate mitigation measures.

EcosHaz project intends to overcome the aforementioned limitations and weaknesses by i) reviewing and analyzing the available frameworks, methodologies and tools ii) providing state of the art guidance as well as necessary data sources and support structures for the economic assessment of coastal risk prevention measures iii) validating the applicability of the developed materials.
