Generic framework for meso-scale assessment of climate change hazards in coastal environments


General Information:

Author: Rosendahl Appelquist, L.

Year of publication: 2013

Available languages: English

Details of Assessment:

Type of assessment: Vulnerability assessment

Details: Hazard assessment

Format of assessment: Scientific article

Details: Graphical tool developed as a universal coastal classification system

Estimated costs for conducting: Open source

Estimated duration of assessment: No information

To be carried out by whom: Others

Details: Coastal stakeholders

Institutional scale of use: Multiple (see details)

Details: Local/community, regional, national

Assesment to be used by which target audience: Multiple actors

Details: Regional and national decision makers in developing countries

Output: Report

Details: The report provides information on the degree to which key climate change hazards are inherent in a particular coastal environment, and covers the hazards of ecosystem disruption, gradual inundation, salt water intrusion, erosion and flooding


Coverage & Methodology:

Region of origin: Europe

Developed by which sector: Science

Applied in practice: No information

Geographic coverage in analysis: Worldwide

Potential geographic coverage: Worldwide (coastal environments)

Sectors covered: Biodiversity

Details: Ecosystems

Method used: Mixed method approach

Description of methodology: Hazard graduation that is based on a qualitative analysis of how the various hazards apply to the coastal categories defined in a classification system. Four levels of graduation are defined so that 4 equals very high hazard presence, 3 equals high hazard presence, 2 equals moderate hazard presence and 1 equals low hazard presence. Each generic environment has been assigned a specific inherent hazard level for ecosystem disruption, gradual inundation, salt water intrusion, erosion and flooding in the CHW. The graduation is displayed as a combined number/colour code to give the user the best possible overview of the many subsections

Risk framework used: No explicit use of risk framework

Risk components incorporated: Hazard

Hazards and impacts considered in the assessment: Loss of biodiversity, Coastal erosion, Salinisation, Flood

Source of required data: Primary and secondary

Details: It is recommended to use a combination of remote sensing, onsite assessments, geophysical data and geological maps for the coastal classification. If an assessment is carried out primarily based on remote means, one should be aware of the associated uncertainties, especially related to the sediment balance estimates

Temporal scale: Forward looking

Participatory elements: No

Consideration of interconnectedness and -dependencies of risks: No

Details: SOEs only

Adressing uncertainty: Partly

Details: It is believed that the four-grade system provides sufficient information to be relevant for regional planning purposes, while at the same time appropriately reflecting the uncertainties associated with the hazard graduation methodology

Scope of assessment: Other

Details: Identification of hazards in coastal environments

Relevance for losses and damages:

Economic/Non-Economic losses incorporated: None

Applicability for entire risk spectrum (from extreme weather events to slow onset processes): No


Recommendations for Adaptation measures included in Climate Risk Assessment: No

Usefulness for political purposes: It can be used for coastal management at local, regional and national level and is well-suited for facilitating communication and information exchange between different management levels, scientists and policy-makers

Applied by whom: UNEP DTU partnership

Open access: Yes
