Ranking Port Cities with High Exposure and Vulnerability to Climate Extremes: Exposure Estimates


General Information:

Author: OECD

Year of publication: 2008

Available languages: English

Details of Assessment:

Type of assessment: Vulnerability assessment

Details: Estimates exposure and vulnerability caused by changing climate, disasters and risks for 136 port cities around the world

Format of assessment: Report

Details: Offers method to produce ranking of city vulnerability to coastal flooding

Estimated costs for conducting: Not specified; extensive data accumulations might be expensive

Estimated duration of assessment: Not specified; extensive data accumulation might be time-consuming

To be carried out by whom: Government representatives

Institutional scale of use: Local/community

Details: Port cities with more than a million inhabitants

Assesment to be used by which target audience: Local decision makers

Output: Report

Details: This analysis provides a tool to rank global port cities which are/might be most subjected to coastal flooding exposure and other risks posed by climate change, also in economic terms


Coverage & Methodology:

Region of origin: Europe

Developed by which sector: Development cooperation

Applied in practice: Yes

Geographic coverage in analysis: Worldwide

Potential geographic coverage: Port-cities with coastal access

Details: Comprehensive analysis that investigates population and assets exposed to risks (no specific sectors are mentioned)

Method used: Mixed method approach

Description of methodology: Mixes qualitative and quantitative approaches based on extensive data and own criteria; combines different analysis with existing modelling approaches. e.g. flooding analysis based on elevation data

Risk framework used: No explicit use of risk framework

Risk components incorporated: All

Hazards and impacts considered in the assessment: Cyclone (including tropical storm, hurricane and typhoon), Extreme rainfall, Flood, Landslide, Sea level rise, Storm surge

Details: Different datasets are consulted, e.g. population data, vulnerability data elevation data specific to each of the cities examined

Participatory elements: No

Consideration of interconnectedness and -dependencies of risks: Partly

Details: Combines exposure data with population and economic growth resulting in an analysis of how climate change / floodings affect assets & population

Adressing uncertainty: No

Scope of assessment: Identification of risks, assessment of impacts, identification of adaptation options, priorization of adaptation options

Details: Directed towards assessment of exposure

Relevance for losses and damages:

Economic/Non-Economic losses incorporated: Both

Details: Refers to the exposure of economic assets as well as other socio-economic variables (populations)

Applicability for entire risk spectrum (from extreme weather events to slow onset processes): Yes

Details: Refers mainly to EWE and for eg: sea-level-rise


Recommendations for Adaptation measures included in Climate Risk Assessment: Partly

Details: Throughout this report, the need for adaptation strategies is stressed, but no concrete recommendations for adaptation are provided

Usefulness for political purposes: Development plans, NAP

Applied by whom: OECD

Open access: Yes
