This dissertation examines the quality of hazard mitigation elements in a coastal, hazard prone state. I answer two questions. First, in a state with a strong mandate for hazard mitigation elements in comprehensive plans, does plan quality differ among county governments? Second, if such variation exists, what drives this variation? My research focuses primarily on Florida’s 35 coastal counties, which are all at risk for hurricane and flood hazards, and all fall under Florida’s mandate to have a comprehensive plan that includes a hazard mitigation element. Research methods included document review to rate the hazard mitigation elements of all 35 coastal county plans and subsequent analysis against demographic and hazard history factors. Following this, I conducted an electronic, nationwide survey of planning professionals and academics, informed by interviews of planning leaders in Florida counties. I found that hazard mitigation element quality varied widely among the 35 Florida coastal counties, but were close to a normal distribution. No plans were of exceptionally high quality. Overall, historical hazard effects did not correlate with hazard mitigation element quality, but some demographic variables that are associated with urban populations did. The variance in hazard mitigation element quality indicates that while state law may mandate, and even prescribe, hazard mitigation in local comprehensive plans, not all plans will result in equal, or even adequate, protection for people. Furthermore, the mixed correlations with demographic variables representing social and disaster vulnerability shows that, at least at the county level, vulnerability to hazards does not have a strong effect on hazard mitigation element quality. From a theory perspective, my research is significant because it compares assumptions about vulnerability based on hazard history and demographics to plan quality. The only vulnerability-related variables that appeared to correlate, and at that mildly so, with hazard mitigation element quality, were those typically representing more urban areas. In terms of the theory of Neo-Institutionalism and theories related to learning organizations, my research shows that planning departments appear to have set norms and rules of operating that preclude both significant public involvement and learning from prior hazard events.

In 2020, the world and foremost vulnerable groups are facing “new” challenges. Dual crises of coexisting hazards like natural hazards occurring amid the COVID-19 pandemic has become more than a prediction. Hence, this thesis is a case study of dual crises and of how organisations and actors act upon those crises. With the aim to examine how the United Nations Office for Disaster Risk Reduction (UNDRR) includes vulnerable groups in disaster risk reduction related matters amid the COVID-19 pandemic, a qualitative text analysis has been performed on the selection of five of UNDRR’s publications. Developed from the Sendai Framework for Disaster Risk Reduction’s four ‘Priorities for Action’ guidelines, four analytical questions were asked to the material. The findings suggest that UNDRR does include vulnerable groups by mainly addressing the lack of resilience among vulnerable groups. However, a lack of concrete suggestions on how to strengthen vulnerable groups resilience and effective responses in the long term was noted. Due to the short time frame in which COVID-19 has existed, the research on vulnerable groups in dual crises of various hazards are still scarce, but nevertheless very much needed as to develop responses adapted towards both biological hazard and natural hazard impacts.

Künstliche Terrassen sind künstlich konstruierte Trockenmauern, die Hänge in Ebenen unterteilen. Petra im Süden Jordaniens gehört zu einer trockenen Klimazone, die sich durch unwegsames Gelände und eine mit Terrassen durchsetzte Landschaft auszeichnet. Die vorliegenden Ergebnisse wurden vom Autor im Rahmen einer multidisziplinären Studie gesammelt, die aus Vermessungen, Erkundungsgrabungen, geophysikalischen Prospektionen, Untersuchungen der Bodentextur sowie chemischen Analysen, optisch stimulierender Lumineszenzdatierung (OSL), Radiokohlenstoffdatierung (14C), Phytolithanalysen und geografischen Analysen zur Untersuchung der Terrassen in einem Gebiet von etwa 391 km2 bestand. Die vorliegende Studie zeigt, dass die künstlichen Terrassen in Trockengebieten für eine Vielzahl von Funktionen konzipiert und genutzt wurden. Die Terrassen dienten somit der Rückhaltung, Sammlung und Verteilung von Boden und Wasser und verhinderten, dass Wasser unkontrolliert abfließt und Erde weggespült wird. Das trockene Klima, das raue Gelände und die für dieses Gebiet charakteristischen Überschwemmungen machten diese Eingriffe in die Natur notwendig. Neben diesen beiden Hauptaufgaben konnten die Terrassen der Nabatäer noch andere Funktionen erfüllen. Neben der landwirtschaftlichen Nutzung der Terrassen nutzten die Nabatäer sie auch zum Schutz ihrer Infrastruktur wie Straßen und hydrologische Einrichtungen. Ein Aspekt, der in der Forschung noch nicht diskutiert wurde. All dies deutet darauf hin, dass die Nabatäer die Gegend sehr gut kannten und gezielt den Bau einer bestimmten Art von Terrasse nutzten. Basierend auf verschiedenen Datierungstechniken begann der Bau der Terrassen in Petra um 350-320 v. Chr. Drei zeitliche Höhepunkte in der Bauausweitung lassen sich unterscheiden: um das 1. Jahrhundert n. Chr., um das 6. bis 7. Jahrhundert n. Chr. und um das 12. Jahrhundert n. Chr. / Man-made terraces are often-overlooked feature in the landscapes of southern Jordan, especially around Petra. These features are artificial constructions dry walls that create flat surfaces on slopes (Spencer, J. and Hale, G. 1961: 3; Treacy, J. and Denevan, W. 1994: 93; Kvapil, L. 2013: 6612). These terraces are usually attributed to have agricultural functions, which is only partially true. This study shows that terraces constructed in arid areas have been designed and used for a wide set of functions that go beyond their agrarian aspects. Petra, located in the south of Jordan, falls within an arid climatic zone, is of rough terrain, and has a landscape dotted with terraces. A multidisciplinary study was conducted by the author which included survey, sounding excavations, geophysical prospecting, soil texture and chemical analysis, Optical Stimulating Luminescence (OSL), radiocarbon dating (14C), phytolith analysis and spatial analysis for studying the terraces. Two major functions were assigned to the constructed terraces: hydrological (water) and pedogenic (soil). Applied to prevent, retain, collect and distribute soil and water. Nabataeans managed to apply terraces to a wide range of fields such as: agriculture, infrastructure such as roads and hydrological installations, an aspect never discussed before. The study concluded, based on OSL, pottery sherds and 14C dates, terrace construction in Petra started around 350-320 B.C.E. at the upper catchment areas, probably for flood water mitigation. Three peaks in the construction expansion can be grouped: around the 1st century A.D, around 6th -7th century and around 12th century, which correspond to more humid climatic conditions and stability in the political situation.
