Can historic natural disturbances enable conservationopportunities? Evidence from the establishment of nationalparks in Sweden
No full textThis study investigates conservation establishment and management in the context of Sweden's 30 national parks by conceptualising natural disturbances as focus events for conservation opportunities. Since positive effects on the environment manifest a long time after a natural disturbance, it may take time before society sees a need to conserve the natural area. To conceptualise such delayed responses to a focus event, the concept of a 'delayed window' is introduced. An analysis of Park Establishment Proposals from the Swedish Parliament for establishing and extending Sweden's national parks was conducted by sending a survey to county representatives for each national park (response rate 19/30). The results show that historic natural disturbances were mentioned as a motivating factor for establishing many of Sweden's 30 national parks (37%, i.e. 11 parks). The result suggests that the delayed window opens when biodiversity and Cultural Ecosystem Services (CES) values of historic disturbance(s) become visible. The time span for motivating values is calculated for biodiversity values (18-829 years) and CES values (5-829 years). However, surveyed representatives responded that future disturbances may not be desired or only desired if controlled or limited, highlighting a paradox in terms of the perceived value of past and future disturbances.This paper was included as a manuscript in doctoral thesis entitled "Natural Hazards as Windows of Opportunity for Change: Character and Time Perspectives on Environmental Opportunities and Preparedness", KUS 2023:7.</p
Disasters as an opportunity for improved environmental conditions
No full textThis paper presents case studies where disasters provided a window of opportunity for change that included social action with (potentially) positive effects on the environment. The research literature was screened for empirical cases in support of societal changes with a focus on environmental issues, and a more in-depth case study of the extensive tree felling after the storm Gudrun in Sweden 2005 was also conducted. The case study is explored through available research as well as “grey” literature to identify societal actions taken after the storm that had – or not – an effect on environmental conditions. With the help of the framework presented by Birkmann et al. (2010), the study aims to characterise the nature of these anthropic changes. The framework was modified to focus specifically on societal actions implemented because of an “open window”, and the environmental effects of the actions. This enabled identifying changes with a positive/negative and intended/unintended effect on the environment, as well as determining if a change was based on formal or informal decisions. Several cases identified in the literature provide empirical support for the theory that disasters can generate a window of opportunity for positive environmental change. However, open windows are not always exploited, as is apparent in the case of the storm Gudrun
Framework for evaluating the maintenance of a Tsunami Early Warning System (TEWS) – A pilot case study in Patong, Thailand, of social and technical quality indicators
No full textAbstractDue to a tsunami being a rapid event (minutes or hours), it is necessary to have disaster risk reduction measures in place well in advance. TEWS is a warning system for reducing the consequences of a tsunami. A successful TEWS requires that i) people are aware of the risk, ii) people are prepared to evacuate and iii) the TEWS is working properly. This study aims to develop a framework with key quality indicators for technical, social, and governance maintenance of a TEWS, emphasizing the chain of activities from tsunami detection to evacuation. The framework is extended to novel indicators involving memory keeping and evacuation signage. The TEWS etsablished in Patong, following the Indian Ocean tsunami disaster 2004, is used as a pilot case study to test the framework related to technical and social maintenance by conducting a retrospective long-term analysis years 2005–2022. Data is collected from research and news articles 2005–2022, as well as field observations of Patong in 2022. The result shows that during these years there have been several events and actions that highlight both problems and positive developments related to technical and social maintenance of the TEWS. Because tsunamis are fast occurrences, dependable TEWS are vital

Success factors and barriers for the integration of adaptation into local RVA : An examination of the municipalities in Värmland
No full textAtt klimatet förändras är konstaterat, skulle utsläppen av växthusgaser kraftigt minskas kan de påbörjade klimatförändringarna ändå inte helt förhindras. Förändringarna innebär att extremväder kommer inträffa oftare men med geografiska skillnader. Till seklets slut väntas i Värmland exempelvis nuvarande tioårsregn istället inträffa var femte år. Vänern kommer i och med detta utgöra en av de största översvämningsriskerna. Hur dessa förändringar påverkar samhället varierar beroende på samhällets konstruktion och sårbarheter. Anpassning till de nya förutsättningarna är nödvändig, och ett stort ansvar vilar på våra kommuner i och med den ansvarsfördelning som finns i Sverige. Möjligheterna att genomföra anpassningsåtgärder varierar, liksom hur långt arbetet har kommit. Ett sätt att integrera klimatanpassning i riskhanteringen för att minska samhällets sårbarhet, är att kommunerna använder sig av sina risk-och sårbarhetsanalyser (RSA). Detta är dock förenat med en del barriärer. Intervju har genomförts med elva Värmländska kommuner. Därtill har genomgång gjorts av samtliga kommunala RSA 2015-2018 för att identifiera framgångsfaktorer och barriärer med integreringen. Dessutom utreds om kommunerna efterfrågar hjälpmedel för detta arbete. Resultatet visade att sex kommuner i varierande omfattning inkluderat klimatanpassning i RSA, vilket är en tydlig ökning jämfört med tidigare års RSA. Dessutom kan både framgångsfaktorer, barriärer och önskemål för fortsatt utvecklande av detta arbetssätt påvisas. Denna undersökning kan visa på att ett samband finns mellan om klimatanpassning i RSA skett och om kommunen drabbats av naturolycka. Dessutom kan samverkan mellan kommunerna vid upprättande leda till att kommuner som inte tidigare drabbats, ändå klimatanpassar RSA genom att samverka med de som har det. Som hjälp vid det fortsatta arbetet med RSA önskas av samtliga intervjuade kommuner ett utökat regionalt samarbete samt någon form av guide eller riktlinjer från exempelvis länsstyrelsen.The climate change is confirmed. Even if greenhouse gas emissions were greatly reduced, it would still not be sufficient to completely prevent the ongoing climate change. This change means that extreme weather will occur more frequently, but with geographical differences. Moving toward the end of the century, in Värmland it is expected that the current ten-year rain cycle will change to a cycle spanning five years. Vänern will be one of the largest flood risks. How these changes affect society varies according to social structure and vulnerabilities. Adapting to the new circumstances is necessary, and great responsibility rests on our municipalities following the distribution of responsibility that exists for municipalities in Sweden. The conditions for implementing adaptation measures vary, as well as how far the work has come. One way to integrate climate adaptation of risk management to reduce the vulnerability of society, is that municipalities make use of their risk and vulnerability analysis (RVA). This, however, is associated with some barriers. Interviews were conducted with eleven municipalities in Värmland and as well as a briefing of all municipal RVA from 2015 to 2018 to identify the success factors and barriers to integration. Also investigated is whether the municipalities are requesting tools for this work. The results showed that six municipalities, though in varying degrees, have included climate adaptation in RSA. A clear increase compared to the previous year's RSA. Additionally, success factors, barriers and requests for further development of this approach appear. This investigation may show that a relationship exists between climate adaptation in RVA occurred and if the municipality is affected by a natural disaster. Also shown is that cooperation between municipalities in the preparation can lead to municipalities that have not previously suffered from a hazard, choose to climate adapt RVA by interacting with those who have. To aid in further work with RSA, an extended regional cooperation is desired by all interviewed municipalities as well as any kind of guide or guidelines, for example, on a regional level
Increase of Biogas Production at Wastewater Treatment Plants Addition of urban organic waste and pre-treatment of sludge
No full textAnaerobic digestion of organic matter results in the production of biogas, which can be used to replace fossil fuels. There is potential for increased biogas production at wastewater treatment plants by digesting urban organic waste either separately or together with the sludge. Biogas production could also be increased by sludge pre-treatment. The objective of this work was to evaluate the potential for increased biogas production at wastewater treatment plants by: 1) digestion of urban organic waste either separately or together with sludge, and 2) sludge pre-treatment/enhanced hydrolysis by enzyme addition, thermal treatment or ultrasonic treatment. Source-sorted organic household waste constitutes a large potential for anaerobic digestion. The amount of waste generated is high, and it can be separately digested yielding 300-400 Nm3 CH4/ton VSin. Co-digestion with sludge (20:80 on volatile solids basis) is advantageous since the combination leads to higher methane yield than would be expected from separate digestion of sludge and waste. Smaller amounts of grease trap sludge and fruit & vegetable waste are generated in the urban area but these types of waste are still interesting for anaerobic digestion, since their organic contents are high (>90%). Digestion experiments showed that the biogas potential of these types of waste is high, and they are best utilised when they are co-digested with sludge. Separate digestion of grease trap sludge could not be achieved in continuous digestion. Fruit & vegetable waste gave a higher methane content and better methane yield when co-digested with sludge than in separate digestion. Enzyme addition, at different doses, was seen to increase the methane yield from mixed sludge (primary and waste activated sludge) in mesophilic continuous digestion. Different strategies for the addition of enzymes were also studied. Direct feeding of enzymes to the digester results in about the same increase in methane yield as separate enzyme pre-treatment of sludge before digestion. Pre-treatment of biosludge by ultrasonication or thermal treatment was seen to increase the methane production in batch digestion tests. When the methods were followed by digestion with enzyme addition, additional effects were observed on methane production. Thermal treatment (70ºC for 1 h) was seen to increase the methane yield by 20% in continuous digestion of mixed primary and waste activated sludge. Thermophilic digestion of sludge resulted in a significantly higher methane yield than mesophilic digestion. Thermophilic digestion of source-sorted household waste showed only a minor increase compared with mesophilic digestion
Big is beautiful! Climate crisis, local adaptation and the dream of growth : Global problems illustrated by the growth municipality of Karlstad
No full textKlimatanpassning och tillväxt är två intresseområden som kan konkurrera med varandra när vattennära områden ska bebyggas. Vattennära boende bidrar till stadens attraktivitet för att locka fler invånare och skapa tillväxt. Samtidigt är dessa områden utsatta för översvämningsrisk. Anpassning behöver därför ske för ökad säkerhet, eller byggande helt avstås från. Ett komplext problem som skapats genom globala påtryckningar att tillväxt ska strävas efter. Problematiken illustreras genom att använda Karlstad kommun som undersökt fall. Syftet med uppsatsen är att undersöka hur strategier för samhällsplanering och klimatanpassning utformats lokalt i en tillväxtkommun med översvämningsrisk. Studien genomfördes via kvalitativ innehållsanalys samt användande av ramverk för miljörättvisa. Textanalys genomfördes av kommunala styrdokument för samhällsplanering och klimatanpassning. Utifrån analys av resonemang i styrdokumenten kan konstateras att skapandet av en attraktiv stad för att uppnå tillväxt väger tyngre än anpassning. Ur rättviseperspektiv tas inte hänsyn till individers sårbarhet och förutsättningar, då lockandet av önskvärda samhällsgrupper istället prioriteras. Vattennära bostadsbebyggelse är en marknadsföringsmässig tillgång, även om översvämningsrisk finns. Resultatet från undersökningen kan användas för att förstå komplexiteten mellan att prioritera och skydda det samhälle som finns idag, samt skapa ett samhälle där tillväxten är god och anpassning inte konkurrerar med attraktivitet
Natural Hazards as Windows of Opportunity for Change : Character and Time Perspectives on Environmental Opportunities and Preparedness
No full textIn the aftermath of natural hazards, opportunities often arise for society to make changes that prevent future losses. These changes can also have environmental impacts, increase preparedness, and contribute to sustainable development. Due to the loss of biodiversity and land degradation, there is an urgent need for actions promoting positive environmental changes. Reversing the trend of land degradation and biodiversity loss is motivated by various reasons, such as preserving ecosystem functions and services that offer protection against natural hazards and reducing drivers of climate change. However, due to land degradation, loss of ecosystems, and human settlements in hazard-prone areas, it is also necessary to take actions that reduce the risk of tsunamis by improving preparedness. Improved preparedness from a people-centered perspective is a crucial aspect of sustainable development. The four papers that make up this thesis present and apply two new frameworks— one to assess the environmental effect of human-made societal changes, and one to evaluate the maintenance of a TEWS (Tsunami Early Warning System) over time. The two frameworks capture two aspects of change after a natural hazard: i) environmental impacts and ii) Disaster Risk Reduction (DRR). The thesis focuses particularly on time, a common aspect in both frameworks. The results indicate that changes triggered by natural hazards have a dual nature in that their impact on the environment can be both positive and negative. The thesis also provides evidence that past natural hazards can create a delayed window, which can be used as an argument for nature conservation during the establishment of national parks. The framework for evaluating the maintenance of a TEWS shows how difficult it is to operate all parts of the warning chain over time, from tsunami detection to evacuation. If parts of the chain are not maintained, the warning system may not be reliable.Natural hazards can present opportunities for societal change. This thesis analyzes two types of changes: i) those with environmental impact and ii) those aimed at improving tsunami preparedness. It addresses a crucial gap in post-disaster literature by focusing on the environmental impacts of changes. In light of land exploitation and loss of biodiversity, it is critical to make changes that reverse these trends and support sustainable development. Unfortunately, not all natural hazards can be prevented. Tsunamis can severely threaten coastal communities, requiring preparedness and evacuation. A people-centered approach to preparedness is also an essential aspect of sustainable development. The thesis includes four papers that present and apply two new frameworks—one to assess the environmental impact of societal changes and another to evaluate the maintenance of Tsunami Early Warning Systems (TEWS). The results reveal that changes, even if well-intentioned, made after natural hazards can have both positive and negative impacts on the environment. The TEWS maintenance framework also highlights the ongoing challenges in maintaining all warning system components
Datorbaserade hjälpmedel för dyslektiker
No full textDatoriseringen i arbetslivet slår ut många dyslektiker på grund av att den kräver att man stavar rätt, samtidigt som dator kan vara till en otrolig hjälp vid rätt användning. Syftet med detta arbete var att beskriva bra dator-baserade hjälpmedel för dyslektiker. Mina metoder var att intervjua människor som är insatta i branschen, besöka resurscentrum och söka på Internet och i litteratur. Jag kom fram till att man kan dela in de datorbaserade hjälpmedlen i två stora grupper, träningsprogram och kompensatoriska program. Träningsprogram används för att öva upp färdigheter medan kompensatoriska program hjälper användaren att kompensera sitt eventuella funktionshinder. Jag fann att det finns många bra datorbaserade program för dyslektiker men även brister. De program som fascinerade mig mest var taligenkänningsprogrammen. Det är program som omvandlar användarens tal till text och är ett mycket bra hjälp-medel för dyslektiker. En brist är att det finns för få bra träningsprogram för äldre elever
