- 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.

Effekter av samhällets säkerhetsåtgärder (ESS) : en kartering av arbetet idag med fokus på översvämningar, ras och skred
- 2012
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- I denna rapport redovisas det arbete som pågått inom ESS-programmets första fas inom temaområde naturolyckor. Detta temaområde innefattar skred, ras, erosion och översvämningar. Målet med det arbete som presenteras i denna rapport har varit att skapa en överblick över hurman idag arbetar med dessa frågor i Sverige med fokus på kommunal nivå. Arbetet utgörs aven sammanställning av tidigare studier, beskrivning av metoder samt intervjuer med svenska och norska kommuner och myndigheter. I de svenska kommunerna har politiker och tjänstemän intervjuats.Förebyggande åtgärder för att minska sannolikheten för, eller konsekvensen av, olyckor vidtas ofta. Åtgärderna är baserade på en analys eller akut reaktion på en specifik händelse. Vissa åtgärder är platsspecifika och kan vara både fysiska och icke fysiska. Andra åtgärder är mer generella såsom lagstiftning och utbildningsinsatser, regional, nationell och internationell policy, direktiv och ramverk.

Landslide risk management : A brief overview and example from Sweden of current situation and climate change
- 2013
-
Ingår i: International Journal of Disaster Risk Reduction. - : Elsevier. - 2212-4209. ; 3:March, s. 44-61

Tidskriftsartikel (refereegranskat)abstract
- Landslide risk is a function of the probability of the event and its consequences. Previous research has shown that preventive measures to reduce the risk are preferred over reactive measures but, especially in developing countries, rarely undertaken. A contributing factor is the lack of evidence that preventive measures pay. This study includes a brief overview of landslide risk management in general and an investigation of the present risk management situation in Sweden based on interviews in 11 municipalities complemented with interviews in Norway. The result shows that climate change has become part of the general awareness and started to be taken into account in the municipal spatial planning. Landslide susceptibility maps and databases are useful tools in the complex spatial planning. The results indicate that the application of landslide susceptibility and risk maps as previously applied for preventive measures and spatial planning in the landslide prone area Gota alv river valley have been cost effective. Improved documentation and more active communication among different stakeholders would, however, contribute to more effective landslide management.

Konferensbidrag (refereegranskat)abstract
- In a project funded by the Swedish Civil Contingencies Agency, the effort and work to reduce different kinds of accidents are being evaluated. The project wants to illuminate the links between actions and outcome, so we can learn from today’s performance and in the future select more effective measures and overall deal with accidents more efficiently. The project ESS covers the field of frequent accidents such as sliding accidents at home, in house fires and less common accidents such as chemical and land fill accidents up to even more rare accidents such as natural accidents and hazards. In the ESS project SGI (Swedish geotechnical institute) will evaluate the work and effort concerning various natural hazards limited to landslides, erosion and flooding. The aim is to investigate how municipalities handle, especially prevention, of such natural disasters today.The project includes several aspects such as:which are the driving forces for risk analysis in a municipalitydo one use risk mapping (and what type) in municipal risk analysiswhich aspects are most important when selecting preventive measuresin which way do one learn from past accidentsand from previous accidents elsewhere, by for example use existing databasesetcThere are many aspects that play a role in a well-functioning safety promotion work. The overall goal is to examine present work and activities, highlight what is well functioning and identify weak points. The aim is to find out where more resources are needed and give suggestions for a more efficient security work. This includes identification of the most efficient “tools” in use or needed. Such tools can be education, directives, funding, more easily available maps and information regarding previous accidents and preventive measures etc. The project will result in recommendations for more effective ways to deal with landslides, erosion and flooding. Since different kinds of problems can occur depending on level of authority the investigation of the security work will be done with authorities on both regional and local scale. At the moment the investigation process are in progress and preliminary results will be presented.

Efficiency of preventive actions for landslides and flooding : evaluation of Scandinavian practices
- 2011
-
Konferensbidrag (refereegranskat)abstract
- The results presented here covers natural hazards with focus on land slides and flooding. The results are based on Swedish/Scandinavian contexts. Natural events such as erosion, flooding and land slides are common, but the number of accidents (events causing severe negative impact) is rare. Therefore, in such analysis there is limited data and other information available which can be used for example in statistical analysis of actions and their effects. Instead, the analysis must be based on other information. The analysis may have to include aspects that only can be assessed by scenario and "what-if" analyses.In this project the main method has been interviews with officials in Swedish municipalities and national agencies in Sweden and Norway. In all municipalities, one politician and officials working with planning and rescue service have been interviewed. The study covers hazard and risk mapping, follow up of such maps, physical planning and lessons learned from previous events and activities.The final outcome of the research will be a review of what is found to be well functioning, identification of weak points and recommendations for the management of landslides, erosion and flooding. The present results indicate that hazard/risk maps are of great importance, but the knowledge about the maps and how to use them varies depending on who you ask and between municipalities. Most officials in municipalities are aware of climate change (CC) but, due to high uncertainties and since climate induced events such as natural hazards are rare, the issues are often not prioritized. Further, the results indicate that the documentation, communication and the responsibilities among different units is not always clear, having impacts on for example the knowledge transfer to new personnel.

Development and Initial Validation of the PILCAST Questionnaire : Understanding Parents’ Intentions to Let Their Child Cycle or Walk to School
- 2021
-
Ingår i: International Journal of Environmental Research and Public Health. - : MDPI. - 1661-7827 .- 1660-4601. ; 18:21

Tidskriftsartikel (refereegranskat)abstract
- Children generally do not meet the recommendation of 60 min of daily physical activity (PA); therefore, active school transportation (AST) is an opportunity to increase PA. To promote AST, the involvement of parents seems essential. Using the theory of planned behavior (TPB), the aim was to develop and validate the PILCAST questionnaire to understand parents’ intentions to let their child cycle or walk to school. Cross-sectional sampling was performed, where 1024 responses were collected from parents. Confirmatory factor analysis indicated acceptable fit indices for the factorial structure according to the TPB, comprising 32 items grouped in 11 latent constructs. All constructs showed satisfying reliability. The regression analysis showed that the TPB explained 55.3% of parents’ intentions to let the child cycle to school and 20.6% regarding walking, increasing by a further 18.3% and 16.6%, respectively, when past behavior was added. The most influential factors regarding cycling were facilitating perceived behavioral control, positive attitudes, subjective and descriptive norms, and for walking, subjective and descriptive norms. The PILCAST questionnaire contributes to a better understanding of the psychological antecedents involving parents’ decisions to let their child cycle or walk to school, and may therefore provide guidance when designing, implementing and evaluating interventions aiming to promote AST.

How to measure efficiency in risk prevention?
- 2012
-
Konferensbidrag (refereegranskat)abstract
- Risk assessment methods form corner stones in the striving to reduce risks and threats to human life and society. Proposed actions can be physical or non-physical and adopted or declined after political evaluation, with consideration taken to available resources and estimated effect on risk. To optimize and avoid regrettable actions, decision-makers are in need of well-founded analyses of how efficient different options might be. Analytically, there are several possible steps that can contribute.Firstly, the correlation between a measure and its effect should be based on causality, which often is difficult to establish quantitatively. High frequent accidents (e.g. traffic) can normally be treated statistically , while low frequent accidents with severe consequences (e.g. natural hazards) are more restricted to qualitative descriptions of correlation. Systematic monitoring of injury and damage data and gathering into databases, are a crucial activity for causality valuation. Secondly, economic valuation of effect is an important contribution in a cost-benefit perspective. Thirdly, a measure often brings several different effects and some may fall outside the actual purpose. An additional problem is how to handle effects that exert varied influence on different stakeholders or social groups in society. Fourthly, certain criteria are required for final prioritization. For instance, in analysis of goal fulfillment, effects are compared with politically decided quantified goals.In cases where basic data from steps 1-3 are incomplete, alternative criteria like “acceptable risk” might be necessary to agree about politically. To use similar approaches on how to describe and quantify effect correlations, promote gathered efforts at local level where risk reducing measures are decided upon by different actors and with regard to diverse local conditions. Tests of suitable methods and approaches to measure efficiency of planned or accomplished actions in gain for risk prevention, are described and discussed.

Sustainability Aspects of Flood Risk Management : Interrelations and Challenges
- 2010
-
Ingår i: SELECTED PAPERS FROM IDRC ON RISK REDUCTION AND DISASTER MANAGEMENT. - : HARBIN INST TECHNOLOGY, P R CHINA. ; , s. 101-107
-
Konferensbidrag (refereegranskat)abstract
- Aspects of sustainable development are crucial for Flood Risk Management (FRM). These aspects are relevant for the flood risk analysis, risk evaluation and risk-reduction. Two case studies are used to identify potential conflicts between different values: Lake Vanern and Gota alv River in Sweden and Elbe River in Germany. In both cases there are diverging interests of how to manage the systems, e.g. how to regulate water levels and use floodplains. The conclusion is that the relevant sustainability aspects must be identified, addressed and valued in the risk management process, especially for different risk-reducing measure options.
