1. Extreme Weather and Water-Related Disasters Extreme weather events frequently take place in many parts of the world, causing various kinds of water-related disasters such as windstorms, floods, high tides, debris flows, droughts, and water-quality issues. This is a key issue for the sustainability and survivability of our society. The Asian and Pacific region is one of the most disaster-prone areas in the world. It is very adversely affected by natural hazards such as cyclones and typhoons and tsunami caused by earthquakes and volcanic eruptions under the sea. These natural hazards bring severe disasters to all countries in the region where social change, in terms of population and economic growth, is the most dynamic in the world. Growth in this region of the world has not, however, led to advances in disaster risk management. The situation is getting worse because infrastructure development cannot keep up with growth. Policies for poverty reduction and alleviation are insufficient and the difference between being rich and being poor is increasing. Vulnerable populations are often those hit worst by hazards and disasters. As the world’s cities expand to occupy ever greater portions of the world’s flood plains, riversides and shorelines, the risk of flooding will continue to outpace both structural and nonstructural mitigation efforts. “A natural hazard strikes when persons lose their memory of the previous one.” This quotation is from Dr. Torahiko Terada (1878-1935), a former Professor of the University of Tokyo who influenced many Japanese persons as an educator, physicist and philosopher. Persons tend to forget bad memories if they do not experience a similar event for a long time. This lack of experience and ignorance increases the vulnerability of society to disasters.

The Kentucky Transportation Cabinet (KYTC) and Kentucky Transportation Center (KTC) at the University of Kentucky developed and performed an assessment of the vulnerability of the state’s national highway system (NHS) to extreme weather events and natural hazards. The assessment was designed as a hybrid process that 1) gathered and analyzed existing and available quantitative data on natural hazards, including meteorological hazards and geological hazards; 2) executed a series of workshops at KYTC districts throughout the state to elicit local expert knowledge on transportation system vulnerabilities; and 3) incorporated all data into a single vulnerability assessment. The workshops involved several facilitated exercises, including map-based discussions and keypad exercises to identify vulnerabilities along highway segments. Data from the mapping and keypad exercises were gathered in a geographic information system (GIS) and combined with the other hazard data to identify vulnerabilities for each highway segment. FHWA’s Vulnerability Assessment Scoring Tool (VAST) was used to process all the data into a single and ultimate assessment. Results from this analysis include a district-level prioritized ranking of NHS segments based on their vulnerability to extreme weather and natural hazard events. Additionally, a district vulnerability assessment report for each district highlighted the most vulnerable assets in the district and discussed their vulnerabilities in detail. This research is intended to aid KYTC in identifying at-risk infrastructure and direct the implementation of preparedness and resilience measures, thus helping to protect the integrity of the transportation system and the sound investment of taxpayer dollars.

There would be little disagreement over the media’s crucial role in reporting extreme weather events and natural hazards, which have become more commonplace in Pacific Island Countries (PICs). However, for various reasons explored in this article, the media have generally failed to satisfactorily cover the unfolding of natural hazards and disasters. Using Fiji as an example, this article discusses media coverage of various cyclones, and the gaps in the reporting. The article argues that more training and capacity building for media personnel should be undertaken to ensure that people are well informed and prepared as they face the brunt of more frequent and intense extreme weather events.

Purpose The integral approach to risk is currently an important background for the local development processes within the sustaintability framework. Given the greater frequency and intensity of extreme climatic events in the period 2005-2015, whose inventory shows a total of 78 extreme climate events in the four thermal stations, the purpose of this paper is to analyze risk situations and their corresponding management in the tourist destinations (TD) of the Atlantic coast of Buenos Aires, Argentina. Design/methodology/approach Risk management in TDs has not been addressed in depth in the study area. Because of that, this study is exploratory and descriptive, and it was conducted by quantitative and qualitative methods. The occurrence of extreme weather events was the trigger of this study. Thereafter, the existence of risk situations was analyzed from the combination of natural hazards and material and human damage. The actions taken by the public sector were identified to make a diagnosis of the current management of coastal destinations in the province of Buenos Aires. Findings The result of this study shows that TDs do not apply integral models of risk management, as only 16% of the total registered events were attended by public management from reactive measures to the event. It is believed possible to replicate this study in other TDs, regardless of its main tourism modality, as the analysis carried out in the coastal destinations of Buenos Aires shows that it is necessary to plan and manage risk to avoid and/or mitigate material, social and economic damages of the resident and tourist population. Practical implications The main implication of the study, in practical terms, is associated with the incorporation of specific equipment for the detection of storms and other meteorological phenomena. In addition, it should start, from the management, with a process of awareness of the resident and tourist population about the risk and its consequences. Social implications Knowing the existence of natural hazards is a strategic resource for public management. From the identification of the hazards, exposure and vulnerability of the population, it is possible to begin to take measures to mitigate the risk and conduct awareness campaigns about the risk situations that may arise from the occurrence of meteorological phenomena. in beach areas. In this sense, the development of a culture of risk is very important. Originality/value The relationship between the occurrence of extreme weather events and tourism has not been addressed in depth in Argentina. Therefore, this work provides an interdisciplinary vision (from tourism and physical geography) about the hazards that extreme phenomena represent in TDs, the situations of risk that they detaches there and the weakness of public management in coastal destinations of Buenos Aires. This case study shows that the absence of planning and risk management has serious implications for the continuity of the development processes of the destinations.
