Developing Climate Vulnerability Indicators (CVIs)
Work Package Leader: Dr Barry O’Dywer
Duration: 5 months (March 2017- July 2017)
Adopting a CVI‐based approach, and employing data provided through WP2, this WP will assess and map projected changes in levels of vulnerability to key urban climate changes (sea level, temperature and precipitation). To facilitate the communication of the complexities of vulnerability information, a simple structure is proposed for the development of CVIs with a limited number of factors to determine sensitivity for each risk and types of response. This information will provide all parties that have a related management role and remit with the pre‐requisite information to understand potential current and future vulnerabilities, and on this basis, develop appropriate, flexible and robust management responses.
WP4 will employ information developed through WP3 in combination with existing and available environmental and socio‐economic information to establish spatial and temporal variations in levels of vulnerability to key urban climate changes. This information will then be visualized through a web‐based Climate Vulnerability Atlas (incorporated within Ireland’s Climate information Platform – ICIP), highlighting areas where adaptation is more urgent.
4.1 Delineating Urban Areas
An essential first step in the development of indicators of vulnerability will be the delineation of “urban areas” and “surrounding urban areas”, and the identification of green (e.g. parks) and red areas (built up areas).
4.2 Characterising and Assessing Levels of Vulnerability to Coastal Inundation
Projected inundation data will be combined with existing and relevant sensitivity data (e.g. % commercial, % residential areas, presence and extent of key critical infrastructure assets and networks) and response variables (e.g. availability of flood defences, effective drainage system, green areas) to assess temporal and spatial variations in levels of vulnerability to coastal inundation.
4.3 Characterising and Assessing Levels of Vulnerability to Temperature‐related Health Impacts
Information on projected changes in T2M (average, minimum and maximum) will be combined with existing and relevant sensitivity data (e.g. % population >65 years, % low income households) and response capacity (e.g. education level, life expectancy) to assess spatial and temporal variations in levels of vulnerability to temperature related health‐impacts.
4.4 Characterising and Assessing Levels of Vulnerability to Flash Flooding
Information on current and projected changes in precipitation will be combined with existing and relevant sensitivity data (e.g. land cover and soil sealing) and response capacity (e.g. existence of drainage network) to identify areas vulnerable to flash flood risk.
4.5 Developing Urban Vulnerability Maps
The main conclusions from Tasks 4.2, 4.3 and 4.4 will be mapped and collated in a Climate Vulnerability Atlas in order to facilitate decision makers in understanding when and where adaptation might be required.
