Risk-based vulnerability assessment using IVAVIA

IVAVIA stands for Impact and Vulnerability Analysis of Vital Infrastructures and built-up Areas. The overall aim of a risk-based vulnerability assessment using IVAVIA, the major deliverable of WP2, is to facilitate the understanding of cause-effect relationships of climate change and to assess what impact on people, economy and built-up area under study can be expected now and for the future due to the changing climate. It enables the identification of geographical hotspots of vulnerability, which can be used as entry-point for adaptation measures. The identification of these hotspots will enable prioritizing the areas where actions are needed first. The IVAVIA concept and design has been featured in the RESIN Newsletter #3, one of its first applications in the tier-1 RESIN city Greater Manchester has been reported in the RESIN Newsletter #4.

IVAVIA is a procedure with 9 modules based on the 8 modules of the Vulnerability Sourcebook as published and maintained by the GIZ, Deutsche Gesellschaft für Internationale Zusammenarbeit (GIZ) GmbH (Society for International Collaboration).

Selecting hazards and drivers
Preparing the Vulnerability Assessment
Developing Impact Chains

Identifying and selecting indicators
Data acquisition and management
Normalisation of indicator data
Weighting and aggregating of indicatos
Aggregating vulnerability components to vulnerability/risk
Presenting the outcomes of your vulnerability assessment

The IVAVIA development and application follows the RESIN principle of Co-Creation. In order to use IVAVIA in a correct and consistent way, a first partial IVAVIA Guideline document has been produced and released on January 6, 2017 to the members of the RESIN Consortium covering the IVAVIA modules 0, 1, and 2. This document offers a practical guideline for conducting a risk-based process for assessing impacts and vulnerabilities of urban areas and their infrastructure related to consequences of Climate Change. The objective of this guideline is to describe the methodology in a way that is understandable for the stakeholders, thus providing the base for the collaborative execution of a vulnerability assessment according to IVAVIA.

The application of IVAVIA is embedded in a larger cycle of repeated risk-based vulnerability assessment (IVAVIA), identification of adaptation options, adaptation planning, and implementation (RESIN conceptual framework). IVAVIA starts with preparatory work in module 0. The novelty of this module is a methodical identification of the relevant climate related hazards. The criteria for the selecting the hazards and the sources and studies upon which the selection is based should be documented, as a reference for applying IVAVIA in the next cycle.

Identify an initial overall plan of the project
Identify the hazards considered potentially relevant
Gather information about the identified hazards
Identify relevant drivers and stressors
Kick-off meeting and management decisions

The modules 0-2, as described in the IVAVIA guideline document, have been applied to Bilbao and Greater Manchester so far. Other RESIN cities such as Bratislava will follow in early 2017. Intermediate results of this activity are a set of impact chains. Modules 3–7 are currently under development, with a focus on estimating risk. After the application of module 8, participating cities may end up with an interactive map about their respective city exposed to a hazard of their choice (see Figure for getting an impression how such maps could look like).

However, this is work in progress, happening with the participation of the RESIN tier-1 cities and the RESIN WP 2 development team as part of the co-creation process.


Cities are invited and encouraged to submit comments and feedback on the tool via the RESIN LinkedIn group.
