“…The landslide frequencies differ between Norway and Sweden. While the frequency of landslides in Norway is approximately the same as for Austria and Italy, it has been lower in Sweden which has the same frequency as Switzerland (Andersson-Sköld et al 2013).…”

Quick clay landslides are a special feature of Norwegian and Swedish geologies. Vibrations or small initial landslides can cause a quick clay layer to collapse and liquefy, resulting in rapid landslides with little or no time for evacuation, making them a real threat to human life. Research concentrating on damages due to landslides is scarce, and analyses of loss of human lives caused by quick clay landslides in the scientific literature are, to our knowledge, nonexisting. Fatality quantification can complement landslide risk assessments and serves as guidance for policy choices when evaluating efficient risk-reducing measures. The objectives of this study were to assess and analyze available damage information in an existing data set of 66 historical landslide events that occurred in Norway and Sweden between 1848 and 2009, and access its applicability for quantifying loss of human life caused by quick clay landslides. Fatality curves were estimated as functions of the number of exposed persons per landslide. Monte Carlo simulations were used to account for the uncertainties in the number of people actually exposed. The results of the study imply that the quick clay fatality curves are nonlinear, indicating that the probability of losing lives increases exponentially when the number of exposed persons increases. Potential factors affecting human susceptibility to landslides (e.g., landslide-, area-, or individual-specific characteristics) could not be satisfyingly quantified based on available historical records. Future research should concentrate on quantifying susceptibility factors that can further explain human vulnerability to quick clay landslides.

“…Conflicts among different stakeholders could be decreased through increased transparent documentation and increased communication among different interests and stakeholders (Johansson et al 2006;Andersson-Sköld et al 2013). An important issue in the risk management process is to decide for whom the intervention should be effective and who should be responsible for funding.…”

“…Some of the more important nonphysical measures are education, information campaigns, communication with landowners, subsidies, increased preparedness, and the establishment of risk management networks (Glaas et al 2010;Glavovic et al 2010;Holcombe and Anderson 2010;Andersson-Sköld et al 2013;Bormann et al 2015). Other measures can be recommendations and restrictions in master plans and in detailed spatial planning (Srivastava and Laurian 2006;Holcombe and Anderson 2010).…”

Natural events such as floods and landslides can have severe consequences. The risks are expected to increase, both as a consequence of climate change and due to increased vulnerabilities, especially in urban areas. Although preventive measures are often cost-effective, some measures are beneficial to certain values, while some may have negative impacts on other values. The aim of the study presented here was to investigate two frameworks used for assessing the effectiveness and sustainability of physical and nonphysical flood and landslide risk reduction measures. The study is based on literature, available information from authorities and municipalities, expert knowledge and experience, and stakeholder views and values. The results indicate that the risks for suboptimization or maladaptation are reduced if many aspects are included and a broad spectrum of stakeholders are involved. The sustainability assessment tools applied here can contribute to a more transparent and sustainable risk management process by assessing strategies and interventions with respect to both short-and long-term perspectives, including local impacts and wider environmental impacts caused by climate change, for example. The tools can also cover social and economic aspects. The assessment tools provide checklists that can support decision processes, thus allowing for more transparent decisions.

“…The first step was to assess current adaptation approaches using a meta-evaluation of existing single and cross-case studies published between 2008 and 2013 [13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31][32]. These studies were identified through searching databases of scientific articles using the following search string: adaptation AND (Sweden OR Swedish) AND (urban OR city OR cities OR municipa*).…”

“…To improve adaptation financing, municipalities apply increasingly for national funding to finance large-scale risk-reducing measures [14,25]. Others take out insurance to be prepared for liability claims from disaster-affected citizens [24] (this measure is, however, a grey zone and could alternatively be classified as internal mainstreaming).…”

Climate change poses a serious challenge to sustainable urban development worldwide. In Sweden, climate change work at the city level emerged in 1996 and has long had a focus on mitigating greenhouse gas emissions. City planners' "adaptation turn" is recent and still ongoing. This paper presents a meta-evaluation of Swedish municipal adaptation approaches, and how they relate to institutional structures at different levels. The results show that although increasing efforts are being put into the identification of barriers to adaptation planning, in contrast, there is little assessment or systematization of the actual adaptation measures and mainstreaming strategies taken. On this basis, opportunities for advancing a more comprehensive approach to sustainable adaptation planning at both the local and institutional level are discussed.
