Natural disasters caused by climate change frequently occur around the world. In Korea, flood warnings and storm warnings are used to prepare for flood damage. However, flood warnings are specifically issued for rivers while storm warnings use the same criteria throughout the country. Accordingly, there is a limit to effective flood preparation which reflects the regional characteristics of each administrative district. In this study, the flood risk matrix for each administrative district is developed in order to provide flood risk forecast information that reflects upon local characteristics. Moreover, the applicability is evaluated by using dichotomous forecasting. As a result of the forecast's evaluation, the probability of detection was determined to be over 80%. Therefore, it is possible to prepare for a flood through the forecast information of the administrative district using the flood risk matrix. In the future, it will be necessary to study how to improve the utilization of flood risk forecasting information through the continuous investigation of past damage phenomenon along with a review of flood-influencing factors.

Management Cycle

It is now commonly accepted that the management of flood risks has to be fulfilled within an integrated framework. About two decades ago flood risk was managed from a limited perspective predominantly by means of structural measures aimed at flood control. In contrast integrated flood risk management incorporates the complete management cycle consisting of the phases prevention, protection and preparedness. In theory it is a well described concept. In the stage of implementation, however, there is often a lack of support although a consistent policy framework exists. Consequently, the degree of implementation must be rated as inadequate in many cases. In particular this refers to the elements which focus on preparedness and prevention. The study to which this paper refers emphasises the means and potentials of scenario technique to foster the implementation of potentially appropriate measures and new societal arrangements when applied in the framework of integrated flood risk management. A literature review is carried out to reveal the state-of-the-art and the specific problem framework within which scenario technique is generally being applied. Subsequently, it is demonstrated that scenario technique is transferable to a policy making process in flood risk management that is integrated, sustainable and interactive. The study concludes with a recommendation for three applications in which the implementation of measures of flood damage prevention and preparedness is supported by scenario technique.

AbstractAs climate change accelerates the frequency and intensity of natural disasters, damage to public and private property is also increasing, putting exorbitant strain on governments and communities. Societies across the world are working to adapt to climate change, but climate adaptation is currently inadequate to meet the needs of the people left increasingly vulnerable and the places that risk being irreversibly changed or destroyed. One tactic of climate adaptation is strategic retreat, sometimes referred to as managed retreat. Strategic retreat is the process by which the government or another entity purchases (buys out) developed properties that are at risk of destruction or have been destroyed by natural disasters. The structure is most often demolished, and the land is placed under a permanent easement to prevent future development. What happens next is dependent on the entities involved in the buyouts, and can range from derelict, vacant lots to full restoration of ecosystems and their abilities to mitigate flood damage. Sometimes recreational amenities, such as trails or park infrastructure, are prioritized and funded as well. Conservation organizations can leverage their expertise in conservation planning, land acquisition and restoration, policy advocacy, and partnership development to improve the implementation of strategic retreat so that nature and people can thrive in the long term. In this policy paper, we review ways that conservation organizations have and can continue to engage in buyout processes to ensure positive outcomes for communities and nature. Conservation organizations must also evolve their approaches to climate adaptation to integrate equity and redress historical injustices in land use, and contribute towards improving strategic retreat for a more just and resilient future across disaster-prone communities. This work focuses on the context of disasters and climate adaptation in the USA, though many of the principles presented are applicable around the world.

Pros And Cons

The region of Yushu has fragile natural environment. In 2010, it suffered severe damages caused by earthquakes. This paper subject, on the basis of status research of natural and cultural environment in Yushu area and urban public facilities across the world, is aiming at a design attempt of public facilities suitable for Yushu area under the guidance of sustainable-development design theory. After constructing computer models, we made physical models to further test the reliability of our scheme. The overall design acts according to circumstances, and makes it environmental friendly, developmental sustainable, economical, aesthetic, practical and reliable. We also added to our design some local characteristics to make it better integrate into the local natural environmental features so that it could be widely used. In the end, we summarized the pros and cons of the scheme through theoretical analysis of our design process, despite that, in June 2014, we had an on-the-spot investigation in Yushu, and according to its current state of development, we made outlooks of our further scheme practice.

The aim of the article is to identify the main components of government overall liabilities based on the Fiscal Risk Matrix classification introduced by the World Bank in 1999, and to estimate the amount and structure of these liabilities in European Union countries (EU Fiscal Risk Matrix). The climate liabilities definition and methodology included in the EU Fiscal Risk Matrix is also a novelty of the research. The study covered EU member states in the period 2018–2019, taking into account available data from the Eurostat database. On this basis, the EU Fiscal Risk Matrix was developed with the estimated structure of the burden of government liabilities for individual countries and the EU as a whole. The article used statistical and comparative analysis. The major conclusion of our research involves the proposal to implement a unified European methodology of government overall liabilities classification based on the EU Fiscal Risk Matrix to assess the fiscal debt burden and transparency of fiscal policy.

Abstract. Flood damage can be mitigated if the parties at risk are reached by flood warnings and if they know how to react appropriately. To gain more knowledge about warning reception and emergency response of private households and companies, surveys were undertaken after the August 2002 and the June 2013 floods in Germany. Despite pronounced regional differences, the results show a clear overall picture: in 2002, early warnings did not work well; e.g. many households (27 %) and companies (45 %) stated that they had not received any flood warnings. Additionally, the preparedness of private households and companies was low in 2002, mainly due to a lack of flood experience. After the 2002 flood, many initiatives were launched and investments undertaken to improve flood risk management, including early warnings and an emergency response in Germany. In 2013, only a small share of the affected households (5 %) and companies (3 %) were not reached by any warnings. Additionally, private households and companies were better prepared. For instance, the share of companies which have an emergency plan in place has increased from 10 % in 2002 to 34 % in 2013. However, there is still room for improvement, which needs to be triggered mainly by effective risk and emergency communication. The challenge is to continuously maintain and advance an integrated early warning and emergency response system even without the occurrence of extreme floods.

Abstract. Decision makers in fluvial flood risk management increasingly acknowledge that they have to prepare for extreme events. Flood risk is the most common basis on which to compare flood risk-reducing strategies. To take uncertainties into account the criteria of robustness and flexibility are advocated as well. This paper discusses the added value of robustness as an additional decision criterion compared to single-value flood risk only. We do so by quantifying flood risk and system robustness for alternative system configurations of the IJssel River valley in the Netherlands. We found that robustness analysis has added value in three respects: (1) it does not require assumptions on current and future flood probabilities, since flood consequences are shown as a function of discharge; (2) it shows the sensitivity of the system to varying discharges; and (3) it supports a discussion on the acceptability of flood damage. We conclude that robustness analysis is a valuable addition to flood risk analysis in support of long-term decision-making on flood risk management.

Abstract. During the last decade, most European countries have produced hazard maps of natural hazards, but little is known about how to communicate these maps most efficiently to the public. In October 2011, Zurich's local authorities informed owners of buildings located in the urban flood hazard zone about potential flood damage, the probability of flood events and protection measures. The campaign was based on the assumptions that informing citizens increases their risk awareness and that citizens who are aware of risks are more likely to undertake actions to protect themselves and their property. This study is intended as a contribution to better understand the factors that influence flood risk preparedness, with a special focus on the effects of such a one-way risk communication strategy. We conducted a standardized mail survey of 1500 property owners in the hazard zones in Zurich (response rate main survey: 34 %). The questionnaire included items to measure respondents' risk awareness, risk preparedness, flood experience, information-seeking behaviour, knowledge about flood risk, evaluation of the information material, risk acceptance, attachment to the property and trust in local authorities. Data about the type of property and socio-demographic variables were also collected. Multivariate data analysis revealed that the average level of risk awareness and preparedness was low, but the results confirmed that the campaign had a statistically significant effect on the level of preparedness. The main influencing factors on the intention to prepare for a flood were the extent to which respondents evaluated the information material positively as well as their risk awareness. Respondents who had never taken any previous interest in floods were less likely to read the material. For future campaigns, we therefore recommend repeated communication that is tailored to the information needs of the target population.

Jatiluwih Tourism Attraction as part of the World Cultural Heritage is a tourist product consumed by tourists. Perception of tourists is important to be studied as a reference in the management of tourist attractions. Data collection techniques using survey methods are used to determine tourists' perception of Jatiluwih Tourism Attraction as part of the World Cultural Heritage. Questionnaires are used as research instruments to obtain information from tourists. After the data is collected, then the measurement is done using the Likert Scale. In determining the number of tourist samples used Slovin formula. Based on Slovin formula with a tolerance limit of 5%, the number of samples for foreign tourists as many as 204 people, and the number of samples for domestic tourists as many as 52 people. The total sample count was 256 people. Domestic and foreign tourists give the highest perception of employment opportunities for the community from the management of tourist attractions. Good perception of tourists is also given to the friendliness of the staff in providing service, naturalness and beauty of the scenery around the tourist attraction. The perception of tourists is not good given to the price of souvenirs, ease of access to the internet, availability of souvenirs with local characteristics, and smooth traffic around tourist attractions.

The Impact

Abstract. Experience has shown that river floods can significantly hamper the reliability of railway networks and cause extensive structural damage and disruption. As a result, the national railway operator in Austria had to cope with financial losses of more than EUR 100 million due to flooding in recent years. Comprehensive information on potential flood risk hot spots as well as on expected flood damage in Austria is therefore needed for strategic flood risk management. In view of this, the flood damage model RAIL (RAilway Infrastructure Loss) was applied to estimate (1) the expected structural flood damage and (2) the resulting repair costs of railway infrastructure due to a 30-, 100- and 300-year flood in the Austrian Mur River catchment. The results were then used to calculate the expected annual damage of the railway subnetwork and subsequently analysed in terms of their sensitivity to key model assumptions. Additionally, the impact of risk aversion on the estimates was investigated, and the overall results were briefly discussed against the background of climate change and possibly resulting changes in flood risk. The findings indicate that the RAIL model is capable of supporting decision-making in risk management by providing comprehensive risk information on the catchment level. It is furthermore demonstrated that an increased risk aversion of the railway operator has a marked influence on flood damage estimates for the study area and, hence, should be considered with regard to the development of risk management strategies.
