Choice Approach

Abstract. In mountainous regions, forests play a crucial role in protecting the local population from natural hazards. In cases where existing forests are destroyed, e.g. by wind throws or diseases, the protection function has to be restored through technical measures. To determine the willingness to pay (WTP) for protection against avalanches, a choice experiment has been conducted and different experiment specifications have been tested to determine possible impacts on the results. The present study contributes to a comprehensive assessment of protection measures, and helps to identify efficient solutions based on the judgement of the people potentially endangered by natural hazards. The stepwise approach has the advantage to gradually check data fit, thereby didactically showing an operational way of dealing with different model specifications. The detailed case study can serve as a manual for conducting choice experiments with a similar focus and demonstrates the suitability and caveats of this approach to value protection from natural hazards in general.

<p><strong>Key Words</strong>: Compound events; Multi-hazards; Industry application; Multivariate extreme value theory.</p><p>Abstract:</p><p>Resilience of pre-existing and new-build infrastructure to natural hazards is of key interest for many different industries (e.g. energy, water, transport). In most situations, studies analyzing the risk posed by single natural hazards have already been undertaken and relevant protection measures have been implemented. However, when considering the potential impacts of compound events or multi-hazards there can be less confidence in which combinations need to be considered and how to estimate the risks associated to these multi-hazard scenarios. Certain industries (e.g. nuclear) have already undertaken several projects on the occurrence and risks posed by multi-hazards (e.g. ASAMPSA-E, NARSIS), whereas other industries are still trying to understand their risks and which questions need to be posed.</p><p> </p><p>The EDF Energy R&D UK Centre are part of an industry scheme funded by NERC called the Environmental Risks for Infrastructure Innovation Programme (ERIIP) which aims to connect academics to industrial organisations and undertake translational research. One of the key topics of further research identified by this group is the topic of compound events and multi-hazards. A recent review of knowledge on multi-hazards was undertaken by the British Geological Survey (BGS) which highlighted the state of knowledge across UK infrastructure owners.</p><p> </p><p>This presentation will start by summarizing this review to pull out some key themes for future research in this area. Then, two different ongoing research projects will be outlined which look to address the key themes coming out of the review. One project is attempting to better understand the different multivariate statistical methods that are available for assessing the probability of multi-hazards. The application of the different models outlined in this work will be shown on an example of extreme precipitation and wind speed. The other project aims to better understand the overarching meteorological conditions that can lead to compound flooding at coastal sites around the UK. This focuses less on estimating joint probabilities, but more on producing clear visualisations for end-users.  </p>

The Future

Natural hazards resulting from climate change are increasing in frequency and intensity. As this is not a linear trend but rather by singularities and anomalies including a broad spectrum of climatic and weather extremes with high temporal and spatial uncertainty, focused avoidance strategies are difficult to prepare. However, the effects of climate change are mostly addressed with outdated ‘business as usual’ approaches by governments and most stakeholders, which are unfit to tackle the complexity of current challenges. Coping action for natural hazards is mostly undertaken during and after such events compensating damage through payments and restoration. In the future, pro-active nature-based solutions are needed for risk mitigation and avoiding severe damage through enhancing all facets of biodiversity from species richness, structural roughness, to spatial heterogeneity of ecosystems. This will not avoid extreme weather events, but it will reduce the damage of increasingly appearing natural hazards. However, this strategy cannot be implemented all of a sudden. Long-term and spatial concepts are needed. For this purpose, currently missing governance structures based on geographical, geoscientific, ecological, meteorological, and societal expertise should be installed. In recent years, a good scientific and knowledge basis for the required solutions has been developed, which now must translate into action. Here, a series of suggestions is compiled for a broad spectrum of extreme events and societal fields, which is far from being complete but should stimulate critically needed creativity and commitment. Nature-based solutions will not deliver a complete protection and cannot be the only kind of action, but we can no longer rely on post-disaster compensation or on the safety illusion of mere engineering and construction works. The efficiency of biodiversity as an insurance for maintaining ecosystem services is well understood. The implementation of nature-based adaptation, coping, and protection measures is less expensive than traditional end-of-the-pipe constructions. It requires an in-depth understanding of interacting processes and trans-disciplinary cooperation based on a broad acceptance in the public. Investments into these solutions would pay off, not tomorrow, but in the future. It is the best sustainable and feasible approach for disaster prevention.

Effect of protection forests on natural hazards due to gravity: Protect-Bio The “Protect-Bio” project of the Federal Environment Agency aims to appraise the effects of biological protection measures, notably protection forests, in such a way that they can be compared to the effects of technical protection measures with the same objectives. A methodology has been developed in the context of the “Protect” project of the National Platform for Natural Hazards (PLANAT) to assess technical measures, which has several stages: preparation, rapid assessment, evaluation of measures, evaluation of effects. This article shows how the methodology for technical measures can be adapted to protection forests. It appears that the principles of the “Protect” project which must be used to evaluate technical protection measures can be applied to biological protection measures. Protect-Bio widens the framework of the danger assessment (danger map) to risk analysis in general. For most danger processes, procedures can be developed for rapid assessment as well as evaluation of measures and effects. Open questions remain concerning evaluation of effects of protection forests with regard to deep and medium level landslides and flooding. It is hoped that in future the protective effects of forests can be taken into consideration in an appropriate and balanced way when assessing dangers and risks.

Abstract. The impacts of natural hazards as well as their frequency of occurrence during the last decades have increased decisively. Therefore, the public as well as the private sector are expected to react to this development by providing sufficient funds, in particular for the improvement of protection measures and an enhanced funding of damage compensation for affected private individuals, corporate and public entities. From the public stance, the establishment of an appropriate regulatory environment seems to be indispensable. Structural and legal changes should, on the one hand, renew and improve the current distribution system of public catastrophe funds as well as the profitable investment of these financial resources, and on the other hand, facilitate the application of alternative mechanisms provided by the capital and insurance markets. In particular, capital markets have developed alternative risk transfer and financing mechanisms, such as captive insurance companies, risk pooling, contingent capital solutions, multi-trigger products and insurance securitisation for hard insurance market phases. These instruments have already been applied to catastrophic (re-)insurance in other countries (mainly the US and off-shore domiciles), and may contribute positively to the insurability of extreme weather events in Austria by enhancing financial capacities. Not only private individuals and corporate entities may use alternative mechanisms in order to retain, thus, to finance certain risks, but also public institutions. This contribution aims at analysing potential solutions for an improved risk management of natural hazards in the private and the public sector by considering alternative mechanisms of the capital and insurance markets. Also the establishment of public-private-partnerships, which may contribute to a more efficient cat funding system in Austria, is considered.

AbstractStructural protection measures are designed to protect the population and infrastructure against natural hazards up to a specific predefined protection goal. Extreme events with intensities that exceed the capacity of these protection structures are called “cases of overload” and are associated with “residual risks” that remain after the implementation of protection measures. In order to address residual risks and to reduce the damages from overload events, a combination of structural protection measures with additional, nonstructural measures is required. Based on data collected through a literature review, a questionnaire survey, expert interviews, and an expert workshop we highlight the status quo as well as key challenges of dealing with residual risks and cases of overload in Alpine countries in the context of geohydrological hazards and gravitational mass movements. We present a holistic conceptual framework that describes the relationships of residual risks, cases of overload, and protection goals in the context of both risk governance and integrated risk management. This framework is valuable for decision makers aiming at an improved management of natural hazards that takes adequate account of residual risk and cases of overload in Alpine countries and mountain areas worldwide.

The paper considers monitoring of environmental change as the central element of environmental regulation. Monitoring, as each kind of principalagent relations, easily gives rise to corruptive behavior. In the paper we analyze economic models of environmental monitoring with high costs, incomplete information and corruption. These models should be the elements of environmental economics and are needed to create an effective system of nature protection measures.

The article offers a method for assessing the environmental risk in the territories adjacent to the planning zone of emergency protection measures around the NPP. The method is based on simulation modeling of territory pollution, which is formed at the late stage of a radiation accident and zoning of territories by risk, taking into account the characteristics of the population’s life in a potentially dangerous territory. A vector criterion of environmental risk is proposed that allows zoning these territories according to the degree of danger to the population.
