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 7 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).

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 offered already 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. In a second phase of co-creation, modules 3-5 have been developed, applied and tested, and finally module 6 has been co-created. In each phase, the IVAVIA Guideline document has been extended and existing parts revised, based upon suggestions made and insights gained during that co-creational phase. In the final version 3 of the IVAVIA Guideline document, all seven modules are covered: their usage is explained and accompanied by practical tips based on experiences in the city case studies.

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.

The modules 0-2, as described in the IVAVIA guideline document, have been applied to Greater Manchester, Paris, Bilbao, Bratislava (RESIN city case studies), and other cities in the UK and the Netherlands so far. Intermediate results of this activity are a set of impact chains. Modules 3–5 focus on quantitatively estimating risk. Here, cities need to determine suitable indicators for components of vulnerability and acquire data for performing calculation of climate change related risk to the exposed assets of the city under investigation. After the application of module 6, participating cities may end up with a map about the risk of their respective city (or parts or assets thereof) exposed to a hazard of their choice (see Figure for getting an impression how such maps could look like).

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