RISK at OECD High Level Risk Forum expert meeting - 2019 - IIASA

Disaster damages and associated socio-economic losses have steeply increased in recent decades. Long-term drivers of hazards and vulnerabilities such as climate change and aging populations are signs that this trend will continue, and even worsen in future if investments are not made to reduce disaster risks. The experience of many governments shows that investments in DRR can pay dividends to limit damages and losses. Yet the cost of building and maintaining protective measures is significant. Budget pressures on OECD governments make cost efficiency and cost effectiveness imperative. This meeting will present and discuss new analytical tools to evaluate the relative efficiency of disaster risk reduction proposals, and the effectiveness of projects that have been implemented already. Among the various methodologies available include different types of cost-benefit analysis (CBA), cost effectiveness analysis (CEA) and multi-criteria analysis (MCA). The methodologies eventually applied to analyze the efficiency and cost-effectiveness of disaster risk reduction projects differ across countries, locations and different types of measures. During the event experts will share knowledge and innovative approaches to evaluating investments in disaster risk reduction. Discussions will focus on structural protection measures, such as levies, coastal dikes and seismic retrofits, but will also consider non-structural measures such as land use prescriptions. In each session an expert will be invited to present case studies to illustrate solutions to a specific conceptual difficulty in the analytical tools used to evaluate the efficiency and effectiveness of disaster risk reduction (DRR) measures. The meeting will convene experts from OECD governments as well as research institutes and intergovernmental organizations where the development of relevant methodologies is conducted. The outcomes of this meeting will be summarized in a synthesis note presenting a comparison of practices across countries, and discussed at the 9th meeting of the High Level Risk Forum, December 3-5 at OECD headquarters in Paris. RISK presentations "Monetizing the benefits of multi-purpose resilient infrastructures", September 19, 15:30-16:30 Reinhard Mechler (RISK, IIASA) and Thomas Schinko (RISK, IIASA) Recently, international policy debate has started to emphasize the need for focusing DRR investment toward actions that generate multiple dividends, including reducing loss of lives and livelihoods, unlocking development, and creating development co-benefits. Decision support tools such as CBA can integrate these co-benefits or “dividends” into the calculus. This session will explore what economic effectiveness tools can be used to monetize or estimate the value of hard and soft resilience tools and their co-benefits. . "Operationalising Broader DRR Frameworks to include Community-based Projects in National Disaster Risk Programmes", September 19, 11:45 -13:00 Thomas Schinko (RISK, IIASA) and Markus Leitner (Environment Agency Austria) Disaster risks can require responses and preparations at various scales. These often require planning and preparation between the national and subnational (i.e. municipal) levels of government and among communities. Tools such as comprehensive climate risk management (CRM) at the local and national level in Austria involve a layering of DRR at local and national levels to enhance coverage of communities and populations. CRM may include fiscal risk assessments with longer-term budget analyses and fiscal stress testing for economic effectiveness at national level, blended with local level training and soft investments. This session will discuss how countries such as Austria measure the effectiveness of multi-layered approaches for DRR through CBA or other tools for multi-layered approaches. .
