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

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.

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.

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.
