Повний текст джерелаThis Bachelor‟s thesis aims at explaining the relationship between forests and climate change, a subject that has been given a lot of attention in environmental discussions in recent years, particularly because forests are a source of carbon dioxide emissions and in the same time have the potential to mitigate climate change through carbon sequestration. However, with the importance of mitigation as a background, the focus of this study is on adaptation. The purpose is to identify mutual benefits from the diverse forest ecosystems, and examine the possible benefits from forests to the rural poor population in Tanzania, in a future scenario of increased vulnerability to climate change. The methodology for the study can be divided into two parts, one qualitative literature study and one field study in Babati District northern Tanzania, limited to interviews and excursions. This thesis gives details about the scientific projections and local perceptions of climate change and the effects of climate change. The results of the thesis highlights the importance of sustainably managed forests and agroforestry systems, which have been successful in Babati through local participation; economic incentives such as carbon credit and other payments for ecosystem services, which is a possible future extension of forestry activities; and increased integration between sectors, which make sure that adaptation within different sectors can be done simultaneously.

Повний текст джерелаGlobal environmental change (GEC) in the ocean threatens marine ecosystems and the people who depend on them. A growing scientific effort is attempting to evaluate the impacts of environmental changes on ecosystems and ecosystem services and guide policy-making to respond to this global issue. Focusing on social-ecological systems of coral reefs, this thesis critically reviews the approaches put forward in the literature to understand gaps and to design new methodologies, assessments, and indicators to guide science and policy. Our findings show that a regionally targeted strategy of research should address complexity and provide more realistic projections about the impacts of GEC on coral reefs ecosystems and ecosystem services. We map global-scale indicators to understand where human dependence on coral reef ecosystems will be affected by globally-driven threats expected in a high-CO2 world. We then analyze how science is responding to the challenge posed by GEC on coral reefs and to identify gaps in research.Finally, we attempt to operationalize an overlooked component of vulnerability assessments, ecological adaptive capacity, to serve as a tool to help assess where local actions can be effective in the context of climate change. This manuscript contributes to theoretical and methodological advances to evaluate impacts, vulnerability and adaptation to GEC. It develops interdisciplinary approaches for the study of social-ecological systems and ecosystem services, targeting coral reefs as a case study. Finally, it synthesizes critically the emergence of a scientific field on solutions to GEC for coral reef social-ecological systems

Повний текст джерелаFreshwater is a precious resource for humankind. Nevertheless, freshwater systems face not only significant anthropogenic pressure but also numerous transformations induced by climate change. Nowadays, climate change is recognized as a serious threat to freshwater ecosystems and, on a global scale, freshwater biodiversity is in rapid decline. In the last few years, epigenetics has been gaining importance in several scientific fields, such as human health and developmental biology. In fact, epigenetic mechanisms can influence phenotype determination and epigenetically acquired phenotypes are known to be inherited across several generations. Therefore, epigenetics is a promising but unexplored topic in a significant number of scientific fields. Taking into account that the global aim of this work was to explore the resilience of freshwater species to cope with the environmental transformations induced by climate change, its main specific objectives were: i) to review the impacts of climate change on freshwater ecosystems, and explore the link between epigenetic mechanisms and the adaptation of different species to the associated phenomena; ii) to assess the relevance of epigenetic mechanisms in the adaptation of Daphnia magna to an increase in water salinity. An extensive review was made leading to the conclusion that climate change is transforming the composition, biodiversity and functioning of numerous freshwater ecosystems. Additionally, this study highlighted that, in the context of climate change, the rise in water temperature and/or salinity are the major threats to freshwater biodiversity, while epigenetic mechanisms can have a decisive role in constraining both short- and long-term adaptation of different taxonomic groups to the environmental transformations induced by climate change. As the second objective was tackled, the exposure of one generation of Daphnia magna to increased salinity showed that there is a molecular adaptation to the hyperosmotic environment at the epigenetic level. For some genes, this epigenetic adaptation was transferred across three successive generations, none of which exposed to the stressor challenging the parental generation. Generally, this work supports the idea that epigenetic mechanisms are a promising topic in the fields of aquatic toxicology and evolutionary biology, as well as in research undertaken in their intersection.
A água doce é um dos recursos mais preciosos para a humanidade. No entanto, para além de serem alvo de significativas pressões antropogénicas, os sistemas dulçaquícolas enfrentam diversas transformações impostas pelas alterações climáticas. Em particular, as alterações climáticas são, hoje em dia, reconhecidas como uma ameaça séria para os ecossistemas dulçaquícolas, sendo que, à escala global, a biodiversidade de água doce está em rápido declínio. Nos últimos anos, a epigenética tem ganho importância em diversos campos científicos, como a saúde humana e a biologia do desenvolvimento. De facto, os mecanismos epigenéticos regulam o aparecimento de novos fenótipos, estando comprovado que os fenótipos determinados epigeneticamente podem ser transmitidos ao longo de sucessivas gerações. Assim, a epigenética é um tema promissor mas largamente inexplorado num grande número de áreas científicas. Procurando avaliar a resiliência das espécies dulçaquícolas para lidar com as transformações ambientais impostas pelas alterações climáticas, este trabalho teve como principais objetivos: i) rever os impactos das alterações climáticas nos ecossistemas dulçaquícolas, explorando a relação entre os mecanismos epigenéticos e a adaptação de diversos grupos de organismos a este fenómeno; ii) avaliar a potencial importância dos mecanismos epigenéticos na adaptação de Daphnia magna a um aumento na salinidade das águas. Uma extensa revisão da literatura foi efetuada, tendo sido concluído que as alterações climáticas estão a alterar a composição, biodiversidade e funcionamento dos ecossistemas dulçaquícolas. Adicionalmente, este trabalho evidenciou que, no contexto das alterações climáticas, o aumento da temperatura e/ou salinidade da água são as principais ameaças para a biodiversidade dulçaquícola, sendo que os mecanismos epigenéticos podem contribuir decisivamente para a adaptação de diferentes grupos taxonómicos, tanto a curto como a longo prazo, às flutuações e transformações ambientais provocadas pelas alterações climáticas. Na abordagem do segundo objetivo desta dissertação, a exposição de uma geração de Daphnia magna a um aumento de salinidade na água induziu uma adaptação molecular, ao nível epigenético, ao ambiente hipertónico. Para alguns genes, esta adaptação epigenética foi transferida ao longo de três sucessivas gerações, nenhuma das quais expostas ao agente de stress a que esteve exposta a geração parental. Globalmente, este trabalho suporta a ideia de que os mecanismos epigenéticos são um tema promissor nas áreas da ecotoxicologia aquática e biologia evolutiva, bem como na interface entre estas duas áreas de investigação.

Повний текст джерелаEn viktig utmaning för hållbar stadsutveckling är att adressera effekterna av de stundande klimatförändringar. För att ta sig an denna fråga har användningen av ekosystembaserad anpassning (EbA), dvs. användningen av ekosystemtjänster för klimatanpassning, främjats av både forskare och utövare. I detta sammanhang behandlar studien två forskningsfrågor: hur EbA ingår i strategisk klimatanpassningsplanering och hur EbA implementeras i praktiken. Studien innehåller en fallstudie- design, där processen från strategisk planering till dess genomförande undersöks i två nordeuropeiska städer: Köpenhamn och Malmö. För att samla in data användes två kvalitativa metoder: en dokumentanalys och semistrukturerade intervjuer med tjänstepersoner på kommuner. Resultaten från studien visar att det finns en hög grad av medvetenhet om de olika EbA åtgärderna, deras potentiella roll för att hantera klimatförändringseffekter och deras synergier i klimatanpassningsplaner. Det praktiska genomförandet av planerna utfördes endast i en projektbaserad skala för att ta med vissa klimatförändringseffekter snarare än på ett holistiskt vis och på en större regional nivå. Den viktigaste EbA åtgärden som användes var utbyggnaden eller omvandlingen av de offentliga grönytorna. Sammanfattningsvis har studien visat på att det finns behov av ett mer heltäckande tillvägagångssätt och ytterligare integrering beträffande användandet av EbA krävs.

Doctoral thesis, Humboldt-Universität zu Berlin, Mathematisch-Naturwissenschaftliche Fakultät II, 2013. http://dx.doi.org/10.18452/16749.
Повний текст джерелаProjecting the effects of environmental change on social-ecological systems is a crucial component of sustainability science. Such projections rely on models and modeling chains. At each modeling step, model-specific uncertainties about parameter values, input data or structure accumulate and lead to a cascade of uncertainty. The aim of this thesis is to explore the cascade of uncertainties in responses to environmental change in a structured way at the example of forest ecosystem modeling. This leads to two overarching research questions: 1. How do different types of uncertainties affect projections of the effects of environmental change on forest ecosystems? 2. What is the general framework of sustainable natural resource management in coupled social-ecological systems in which uncertainties need to be integrated? This thesis shows that forest productivity under climate change may increase in cool and wet regions and decrease in already warm and dry regions. These findings are robust despite large differences in model structure, climate change scenarios and model parameters that induce considerable uncertainty into future projections. It also stresses that there are methods available to assess uncertainties but also that many climate change impact studies have focused on testing the response of plants to changes in mean climate rather than climatic extremes. Finally, this thesis shows that adaptive, cross-sectoral natural resource management strategies exist that accommodate uncertain impacts of environmental and societal change and foster sustainable regional development. I conclude that the cascade of uncertainty challenges sustainable natural resource management and that a more systematic treatment of uncertainties is strongly needed to generate robust projections of the impacts of environmental change. The findings of this thesis provide a general framework in which both modelers and decision-makers can integrate model results and assess their robustness.

Повний текст джерелаThe insurance hypothesis predicts that forests with tree species mixtures may resist better to stressful environmental conditions than forests composed of only one tree species. Most of the currently available literature tested this hypothesis for aboveground productivity and its related response variables, but less is known about belowground processes. In my PhD thesis, I studied the drivers of belowground productivity and decomposition across climatic gradients and how they are affected by tree mixtures. I hypothesized that mixing of tree species with contrasting rooting patterns and fine root morphologies, would result in a release of competitive pressure belowground, and translate into higher fine root standing biomass and increased fine root productivity. Moreover, I hypothesized that roots with contrasting chemical and morphological characteristics in mixed stands would decompose faster, which may be particularly important under nutrient-limited conditions. Under water-limiting conditions, such as during extreme summer drought, I hypothesized overall slower decomposition but an attenuating effect of tree mixtures on decomposition due to improved micro-environmental conditions, in particular for leaves, since roots decompose in a more buffered soil environment. To test these hypotheses I examined the variation in tree root functional traits (across- and within-species), and its consequences for fluxes of C, N and P at the ecosystem scale. I addressed three main objectives and associated research questions to quantify the interactive effect of tree mixtures and climate on: 1) vertical root segregation and fine root standing biomass, 2) fine root dynamics and their associated nutrient fluxes and 3) fine root- and leaf litter decomposition. I could benefit from two different field experiments for my work, one with a 10-year-old tree-plantation experiment with birch and pine close to Bordeaux (ORPHEE experiment), the second along a latitudinal gradient of mature beech forests in the French Alps (BIOPROFOR experiment).I observed that roots from the birch and pine tree-plantation showed similar vertical distribution and similar belowground root standing biomass in tree mixtures compared to monocultures, contrary to my first hypothesis. However, the greater allocation of pine but not of birch to root growth within the top soil horizons under less water-limiting conditions suggests locally favourable conditions that may lead to soil depth-specific asymmetric competition. In the same experiment, fine root production and decomposition were similar in mixtures and in monocultures, in contradiction with my second hypothesis. Moreover, I did not observe any interactive effects of tree mixtures with stand density or water availability. Interestingly though, birch roots, but not pine roots released P during root decomposition, which suggests an important role of birch in the P-cycle and for P nutrition of trees on these P-limited sandy soils. In line with my third hypothesis, I observed a slower decomposition of leaf litter and fine roots in response to reinforced and prolonged summer drought, irrespective of the position along the latitudinal gradient in the Alps. However, this slower decomposition under drought was not attenuated in forest stands with mixed tree species compared to single species stands. Compared to leaf litter, fine roots decomposed slower and released less C. Interestingly, I found a net N release in decomposing fine roots but not in decomposing leaf litter, which suggests a distinct role of fine roots in the N cycle. In conclusion, I found that mixing tree species did not attenuate negative effects of climate change. However, this thesis demonstrates that promoting mixtures can still be beneficial for at least one of the admixed tree species, through species addition (i.e., complementing one tree species with another tree species), as one tree species may facilitate another via belowground fluxes of N and P

Повний текст джерелаAdapting forest management to climate change (CC) is a key issue, as forests are crucial for mitigation policies and the provision of many ecosystem services (ES). Understanding the magnitude of the progress made in this respect can help shape further adaptation developments and avoid the putative maladaptive side effects of forest management evolutions. Here, I aim to bridge the knowledge gap of adaptation implementation in French forests.Chapter 1: Based on semi-structured interviews with foresters, my findings highlight unprecedented aspects of adaptations: (i) a focus on productive ES at the expense of other essential services such as water supply or natural habitats; (ii) adaptations rely on technical changes in forest management and do not deal with climate impacts through organizational or economic tools; and (iii) envisaging ecological processes through adaptations is instrumental and limited to small spatial and temporal scales. My results also extend the existing body of knowledge to the framework of forest management: (i) CC is not the main driver of forestry changes; (ii) extreme events are windows of opportunity to stimulate adaptive changes; and (iii) proactive adaptation to unexperienced hazards is very weak.Chapter 2: Assessment of the diversity of research projects in the forest sciences focusing on CC. I categorized projects according to discipline and main focus, using data from the online description of French public calls for proposals and from selected projects. Since 1997, mitigation research has gradually given way to adaptation. Despite pledges for the inclusion of social sciences, research rarely draws on the social sciences and focuses on ES of economic interest. Biomass production is paramount, being addressed either directly or through projects on tree species of industrial interest. Hence, instead of a diverse search for adaptation strategies, climate research is geared toward a few ES. Without denying the need for timber and biofuel production, I encourage public funders to complement current calls for proposals with more diverse approaches beneficial for both biomass production and other ES.Chapter 3: I study how multiple mechanisms for the mitigation of CC have been developed, drawing on a combination of reducing and offsetting greenhouse gas (GHG) emissions. While mechanisms are mandatory for certain economic sectors, some business that are not required to mitigate their GHG emissions would nevertheless like to do so. I examine two study cases in France to analyze how public and private foresters seized this opportunity to obtain complementary funding from such companies for forestry operations. I focus on offset contracts issued by associations linking public sector forestry agencies, forest landowners, and offset funders. Carbon mitigation was a reason shared by all contractors to commit to the agreement, although it concealed multifarious motivations. Hence, I argue that voluntary offset contracts act like a Trojan horse by enabling foresters to dialogue with entities that would otherwise not be interested in supporting forest management. Regional embedding was crucial to overcoming the mitigation challenges.Chapter 4: To gain insight on how can socio-economic adaptive tools complement technical evolutions of forestry, I designed Foster Forest, a participatory simulation of forest management. It combines a role-playing game, an agent-based model, and a scenario of CC with high uncertainties. Drawing from multiple applications in French regions, I show that climate change is not a short-term matter of concern for private and public foresters. I analyze the emergence of socio-economic changes (mainly payment for carbon storage) in the provision of ES, and participants’ negotiations to spontaneously change the simulation rules. I also highlight how collective adaptive action was steered by stakeholders with a public interest role

Повний текст джерелаThe aim of this thesis is to study allelopathic interactions in the downy oak forest in the mediterranean region and to consider how these interactions can be affected by climate change. We have shown that the dominant tree Q. pubescens and its companion species A. monspessulanum and C. coggygria have different allelopathic potentialities, evaluated in vitro on herbaceous target plants, depending on the phenological stage of the leaves, which could in natura affect the germination and growth of understory herbaceous plants. These differences in allelopathic effect may result not only from differences in the quantity of allelopathic compounds produced, but also from qualitative differences observed as a function of the phenological stage. This suggests that the allelopathic effect may vary over time to match the stage of development of the target herbaceous plants. On one of the target plants used in the bioassays, the allelopathic effects were further accentuated by changing the water and / or thermal conditions which suggests possible modifications of the allelopathic potential of the plants to be expected with climate change.Our results in the plant nursery showed the allelopathic potential of cotinus and pinus on the growth of oak seedlings, whatever the watering conditions (stressed or unstressed). By affecting in particular the biomass of the root system, the growth of which is a key element of the mediterranean species to resist the prolonged summer drought, these interactions could play an important role in the regeneration processes of downy oak

Повний текст джерелаClimate change is now widely seen as a major challenge of this time and the future of cities. However, the most vulnerable will be the urban poor particularly those located on the urban fringes in high risk areas with limited access to basic services and economic opportunities. In South Africa, although progress has been made to reduce socio-economic and environmental challenges created by apartheid legislations, inequalities still exist where the privileged live in safer and well located and serviced parts of the city while he poor are still located in settlements created by apartheid in urban fringes. Spatial Planning presents an opportunity to increase resilience to climate change in vulnerable areas of cities. Through integrating planning and climate adaptation actions, future spatial decisions will add to resilience to climate change and enhance wellbeing of people. The dissertation includes a case study that was conducted to learn about the status quo of the study area to effectively recommend relevant interventions that seek to create resilience to climate change in the area. A local area adaptation plan was then formulated including the framework for implementing proposed interventions in a 20 year timeframe.

Повний текст джерелаMyanmar is a Least Developed Nation, according to the UN, and therefore is highly vulnerable to the negative effects of a changing climate. To assess the relationship between Myanmar and climate change, this thesis analyzes projected impacts on the nation and its people, the current state of adaptation, and how Myanmar’s government has prepared. Projected impacts are viewed through the lens of the most recent IPCC reports and climate models, and discussed in relation to vulnerable areas in Burmese society and governance. This thesis concludes that Myanmar’s environment, people and society are at a significant risk; higher temperatures, altered precipitation rates, and higher sea levels will lead to reduced agriculture output, the spread of disease, and loss of habitable land. Though recent governmental action has laid the framework for suitable adaptation measures, slow progress in past decades has left Myanmar highly vulnerable to the negative impacts of climate change. Myanmar’s next election is scheduled for 2015, and the emerging leaders have the opportunity to make significant progress in climate change adaptation. Cooperation between Myanmar’s new leaders and the international community could accelerate the nation’s adaptation efforts and result in significant progress on climate change preparedness projects.

Повний текст джерелаClimate change impacts, related losses and damages are increasing globally. When these consequences are coupled with increasing global greenhouse gas emission, urban expansion and unsustainable consumption, the pursuit of adaptation to avoid adverse outcomes is a present necessity and a significant future challenge. The overarching aim of this doctoral dissertation is to gain a better understanding of the complexity of climate change impacts on agricultural livelihoods and how adaptation processes enhance adaptive capacity and resilience in Bagri, a small village in northern Ghana. The results presented in this doctoral thesis are based on empirical data obtained between February and July, 2017 in the Lawra District of northern Ghana using qualitative case study research methods: semi-structured interviews, focus group discussions, survey and ethnographic participant observation. Data from the survey were coded and inputted into Statistical Package for Social Scientists (SPSS) version 20 and cross tabulation and analysis of different variables and interpretation of frequencies were done and processed into tables, graphs and percentages. Content analyses of qualitative data were done which allowed patterns and themes in interviews and discussions to be derived and interpreted. The findings show that, people in the studied community have experienced a range of climatic changes with negative impacts on agriculture in the last three decades. In order to adapt to the short duration of the rainy season and low rainfall amounts associated with climate change, smallholder farmers use incremental adaptation strategies such as improved crop varieties and other support strategies. Paradoxically, however, climate change extremes (CCEs) undermined these strategies in several instances, causing crop yields to fall short of their actual potential leading to financial indebtedness. The results therefore, showcase that surmounting non-climatic barriers to the uptake of agricultural adaptation strategies is a necessary but not sufficient condition to achieving successful outcomes, as new barriers in the adaptation process beyond uptake are constantly emerging with CCEs being one example. Secondly, the findings show that climatic changes have necessitated livelihood diversification away from crop production and into off-farm and non-farm activities in Bagri. The results highlight how the process of diversification is dependent on household participation in various group activities and formal and informal social networks. Generally, households in dense social networks were found to be more resilient to perceived climate changes because they had access to the critical resources (material and non-material) essential for diversification. Importantly, the findings shed light on how group activities and social networks can create marginalization and conflicting resource use with the potential of undermining social and ecological resilience in the village. Moreover, this dissertation explores the mechanics of collaborative adaptation governance (CAG) addressing questions of why and how this mode of governance facilitates adaptive capacity. The findings illuminate stakeholder relational dynamics, benefits and failures, and the sustainability challenge of collaborative adaptation governance (CAG) in northern Ghana. More importantly, this study unveils how powerful actors set the agenda, frame problems, and implement rules and incentives contrary to the normative tenets of collaborative governance theory. Ultimately, the results highlights the failures, successes and sustainability challenges of CAG in northern Ghana, while also providing insight into the extent to which CAG approaches can facilitate adaptation to climate change globally. In conclusion, this doctoral dissertation responds to both theoretical and emperical knowledge gaps in the burgeoning climate change adaptation research, and illustrates how invaluable, qualitative case studies can contribute to illuminate some of the elusive themes in the literature and provide evidence for policy making at both local and global levels.

Climate change threatens the function and even existence of coastal cities, requiring them to adapt by preparing for near-term risks and reorienting long-term development. Most policy and academic interest in the governance of climate adaptation has focused on global, national, and local scales. Their efforts increasingly revealed the need to plan for adaptation at the scale of metropolitan regions. This dissertation is the first academic comparative analysis of U.S. regional adaptation initiatives. Drawing on multi-method qualitative research of five coastal regions, I ask: are collaboratives to coordinate adaptation at the regional scale a new form of regionalism? What roles do state policies on climate change and regional governance play? I argue that adaptation collaboratives are an ecological variant of new regionalism that recenters the role of public agencies in advancing adaptation efforts. Adaptation champions have helped overcome limited local adaptation, even where states are antagonistic to climate action, by sharing knowledge, providing technical assistance, and fostering political support. However, most have yet to tackle the limitations of local adaptation. Instead, they have deployed narratives of climate change as predictable and manageable, and of regional adaptation as localized and ecological in ways that mask the need for more transformative developmental and governance paradigms. Only places with regional agencies or county governments that have land use authority, fiscal leverage, or state mandated targets have advanced region-wide zoning and long-term developmental changes. This indicates that state policies towards regional planning institutions are more influential in shaping regional adaptation than those focused on adaptation. Scholarship has shifted away from debates around forms of regional government, but these findings highlight the need to strengthen regional government in order to overcome difficulties in coordinating, implementing, and enforcing multi-sector and multi-jurisdictional responses to climate change. I conclude by calling for a renewed ecological regionalism that articulates a vision of regions functioning as an ecological whole, rather than as the sum of individual parts. I offer recommendations for how collaboratives and other advocates could build awareness and open dialogue about regional interdependence, conflicts, responsibility, and accountability. These processes become pathways to envisioning local preferences for regional governance, build buy-in and coalitions, and advocate for state enabling legislation.

Повний текст джерелаThis thesis investigates the influence of climate change and climatic variability on wetland ecosystems (coastal and inland wetlands) on the Agulhas coastal plain. Firstly, this research examines coastal wetland ecosystem resilience to sea level rise by modelling sea level rise trajectories for the Droё River wetland. The rate of sediment accretion was modelled relative to IPCC sea level rise estimates for multiple RCP scenarios. For each scenario, inundation by neap and spring tide and the 2-, 4- and 8-year recurrence interval water level was modelled over a period of 200 years. When tidal variation is considered, the rate of sediment accretion exceeds rising sea levels associated with climate change, resulting in no major changes in terms of inundation. When sea level rise scenarios were modelled in conjunction with the recurrence interval water levels, flooding of the coastal wetland was much greater than current levels for the 1 in 4 and 1 in 8 year events. The study suggests that for this wetland, variability of flows may be a key factor contributing to wetland resilience. Secondly, the thesis examines the variability of open wetland water surface areas and their relation to rainfall to determine wetland hydrological inputs for the Nuwejaars wetland system and respective wetlands. A remote sensing approach was adopted, Landsat 5 TM and 8 OLI multispectral imagery were used to detect changes of water surfaces for the period 1989 to 2017. Water surfaces were enhanced and extracted using the Modified Normalized Difference Water Index of Xu (2006). The coefficient of variation of wetland water surface area was determined. The variability ranges from low to high for respective wetlands. A correlation analysis of wetland water surfaces and local and catchment rainfall for the preceding 1, 3, 6, 9, 12 and 24 months was undertaken. The preceding month and associated inputs explains the annual variability of surface waters. The study suggests that, the variability of wetland water surface area are related to variations to water inputs and groundwater, as well as variations in water outputs such as evapotranspiration and an outlet channel.

Повний текст джерелаSyftet med denna studie var att undersöka om, samt hur, nationella myndigheter integrerar ett genusperspektiv i klimatanpassning i Sverige. Studien utfördes genom att använda kvalitativ text analys och innehållsanalys av dokument och rapporter från två utvalda nationella myndigheter aktiva i det svenska samhället. I studien användes genusteori och särskilt Yvonne Hirdmans teori Genussystemet. Resultatet av studien visar att nationella myndigheter nämner kön som en viktig aspekt i klimatförändringarna, men även att kön är en avgörande faktor i resultatet av en klimatkatastrof. Studien förtydligar även att ett genusperspektiv i klimatanpassning kan bevisa hur män och kvinnor påverkas olika av klimatförändringarna, samt bidra med lösningar för att undvika kvinnors utsatthet i ett förändrat klimat. En slutsats av studien är att de valda myndigheterna har integrerat ett genusperspektiv i sitt klimatanpassningsarbete. Övergripande brist på information och material kring ett genusperspektiv i klimatanpassning tydliggör dock att ett genusperspektiv inte är helt integrerat i klimatanpassningsarbetet för myndigheter aktiva i Sverige.

Повний текст джерелаDenna avhandling analyserar hur klimatanpassningsprocesser inom privata och offentliga sektorer på regional till lokal nivå i Sverige initieras, utvecklas och genomförs. Avhandlingen ägnar särskild uppmärksamhet åt identifiering av vilka intressenter (”stakeholders”) som är involverade i att underlätta och genomföra anpassning, uppfattningar om anpassningsförmåga samt vilken roll interaktion mellan olika intressenter kan ha för att underlätta anpassning. En kombination av två analytiska perspektiv används som bygger på tidigare forskning om klimatanpassningsprocesser samt transdisciplinär kunskapsproduktion. Studien genomförs inom ramen för två övergripande fallstudier av anpassningsprocesser i en urban region samt den privata skogssektorn. Fallstudierna utgör grunden för insamlingen av det empiriska materialet som bygger på kvalitativa metoder. Den främsta metoden är fokusgruppsdiskussioner med lokala och regionala, privata och offentliga aktörer med intresse av, eller ansvar för klimatanpassning. Fokusgrupperna organiseras som en serie möten där olika deltagandetekniker tillämpas. Studien bygger också på en omfattande intressentkartläggning. I avhandlingen utvecklas och ges förslag på en stegvis metod för att identifiera intressenter för anpassningsprocesser som kan användas inom forskning och praktik. Studien analyserar också hur olika intressentgrupper upplever förmågan att hantera klimatförändringar. Ett antal möjliggörande och begränsande faktorer identifieras så som karaktären på de upplevda klimatriskerna, erfarenhet av klimatvariationer och extrema väderhändelser, samt ansvar- och beslutsstrukturer. Slutligen, analyseras om och i så fall hur interaktionen mellan lokala experter och forskare som deltar i intressantdialoger (”science-based stakeholder dialogues”) kan underlätta anpassning. Resultaten visar att det finns potential genom att deltagarna ges möjlighet att ställa frågor tillvarandra och dela med sig av sina olika kunskapsbaser och erfarenheter, samt utforska olika anpassningsalternativ. Däremot behövs vidare studier för att undersöka betydelsen av det institutionella sammanhanget samt hur olika verktyg (”anchoring devices”) kan bidra när det gäller att förankra och omsätta kunskap om klimatförändringar i olika beslutskontexter. Avslutningsvis visar denna studie på att det finns både likheter och skillnader i hur anpassningsprocesser kommer till uttryck bland de olika aktörsgrupperna inom fallstudierna, t.ex. när det gäller hur begreppet anpassning används, vilken typ av anpassning som identifieras, upplevda möjligheter för anpassning samt graden av komplexitet.

The electric utility sector has been a focus of policy efforts to reduce greenhouse gas emissions, but even if these efforts are successful, the sector will need to adapt to the impacts of climate change. These are likely to include increased heat waves, drought, extreme precipitation events, and sea level rise. Electric utilities play a key role in providing electricity services in cities that will be facing all of these difficulties. Cities depend on electricity service for public health, safety and economic development. This thesis examines how electric utilities in the United States are approaching climate change adaptation and the factors enabling and constraining these efforts. The thesis draws on an analysis of electric utility responses to surveys distributed by the Carbon Disclosure Project as well as case studies of Consolidated Edison, Entergy, and Pacific Gas & Electric. The case study utilities are incorporating climate change projections into their risk management and capital planning activities. Integrating climate change projections into risk management efforts helps utilities use replacement opportunities to build greater resilience into infrastructure systems and ensure that adaptation strategies take competing demands on resources into account. Both approaches to adaptation are generally recommended by adaptation experts. However, existing internal decisionmaking may not be well suited for incorporating the uncertainties of climate change impacts. The case study utilities could be using Scenario Planning to develop strategies likely to be effective given a range of possible futures, but they are not. I argue that state utility regulatory commissions should consider taking a more active role in providing guidance and oversight to utilities regarding climate change adaptation. They should consider (1) requiring utilities to submit climate change vulnerability assessments and detailed adaptation plans; (2) incorporating climate change risk and adaptation considerations into existing electricity plans; and (3) convening joint climate change planning efforts with utilities, municipal governments, and a range of other stakeholders. Cities and states that would like to see electric utilities put more emphasis on climate change adaptation should consider sharing climate change projections and forecasts of potential climate change impacts. Provision of such information has been effective in encouraging adaptation planning in the case studies. The actual adaptation strategies that utilities have adopted depend largely on the risks they face and the regulatory and policy environment in which they find themselves.

Повний текст джерелаThe bio-physical change in the production environment has directed farmers towards strategic alternatives for farming practices. The economic assessment of these adaptation options is of great importance in facing the uncertainty of climate change. However, the economic assessment of farm-level adaptation options remains in its infancy with few empirical studies. The study framework analyzes economic implications of alternative farming activities relating to climate change in several dimensions. The theoretical and empirical economic approach of the study can be characterized in two distinct ways: (1) the process-based approach following farm management theory by production performance analysis and the appraisal of adaptation and (2) the hedonic (Ricardian) approach based on land rent theory and the change in net farm income in relation to climatic variables. The analysis of input-output relations of rice farming was done based on an intensive survey of 300 adapted farmers in Bangladesh over 8 years at different climate thresholds. The study assesses different adaptation options for two rice growing seasons, namely Boro and Amon. These options are (1) low resource use, moderate productive performance and high farm net income, (2) minimum GHG production and (3) farms coping with changing climatic conditions. The study reveals that marginal impacts of temperature on farm net income are negative for all seasons. The marginal impacts of rainfall were found to be positive and significant for all models in the study. It is also evident from the analysis that successive adaptation significantly increases farm productivity and contributes to the revival of farm revenue up to a threshold level. Finally, based on estimated climate variability models of farm net income, the study presents a model that simulates according to future climate change scenarios. It indicates adverse effects of climate change on future farm income.
