The current share of sub-Saharan Africa in global carbon dioxide emissions is negligible compared to major contributors like Asia, Americas, and Europe. This trend is, however, likely to change given that both economic growth and rate of urbanization in the region are projected to be robust in the future. The current study contributes to the literature by examining both the direct and the indirect impacts of quality of institution on the environment. Specifically, we investigate whether the institutional setting in the region provides some sort of a complementary role in the environment-FEG relationships. We use the panel two-step system generalized method of moments (GMM) technique to deal with the simultaneity problem. Data consists of 43 sub-Saharan African countries. The result shows that energy inefficiency compromises environmental standards. However, the quality of the institutional setting helps moderate this negative consequences; countries with good institutions show greater prospects than countries with poor institutions. On the other hand, globalization of the region and increased forest size generate positive environmental outcomes in the region. Their impacts are, however, independent of the quality of institution. Afforestation programs, promotion of other clean energy types, and investment in energy efficiency, basic city infrastructure, and regulatory and institutional structures, are desirable policies to pursue to safeguard the environment.

Swedish political parties are characterized by their markedly different support across geographical space. In most cases, the sources of these regional variations date back to the time of the founding of the parties. Moreover, the regional strongholds and the areas of weak support for the parties have survived major societal changes such as the transition from the agrarian to the industrial society, emigration, and urbanization. Why is it that a certain area evolves a political tradition that sets it apart from neighboring areas? This study addresses itself to this and similar topics with empirical emphasis on the Swedish Social Democratic Party (the SAP).The study is based on the conviction that the regional imbalance in the SAP vote originates in the interaction/competition between various social and political movements in the local environment. The initial model used to explain these imbalances comprises three different factors that influence the party's vote: the socio-economic structure, the local organizational environment and the effect of local party organizational efforts.In order to test the importance of these factors three different areas were selected; one strong, one weak, and one unstable in terms of the Social Democratic vote.The findings show that no single factor alone accounts for the variance in the regional support of the SAP. Rather, what is decisive are the interactions within the structural and social properties of a context.By way of conclusion, this study lends support to the following conclusions of the prospects for the SAP to mobilize the electorate: to establish itself in the local setting the party needs an organizational culture, a local party organization and the absence of strong local opinion against the party's activities and organizational efforts. The party also seems to be favored by a high level of political mobilization (participation), whereas there is nothing to suggest that the SAP's prospects of becoming successful are hampered by competition from the left-wing parties. ; digitalisering@umu

En hållbar utveckling innebär att samhällets begränsade resurser används på ett effektivt sätt med hänsyn tagen till sociala, ekonomiska och miljömässiga konsekvenser. För att uppnå önskade samhällsmål på ett effektivt sätt behöver olika aspekter vägas in vid utformning av styrmedel. Inom EU föregås beslut om regleringar av en så kallad Regleringskonsekvensbeskrivning (Regulatory Impact Assessment) där samhällsekonomisk analys ingår. Forskning och olika utredningar har visat att Sverige saknar en etablerad praxis för att genomföra denna typ av konsekvensanalyser på miljö, men även energi- och transportområdet. I detta projekt är syftet att undersöka hur Sverige arbetar med de analyser av detta slag som genomförs inom EU inför förhandlingar men också att studera orsaker till att de används eller inte används. Fokus ligger på förutsättningar inom en myndighet, men även vilken betydelse som tjänstemän har för vilka underlag som tas fram inför beslut om utformning av regleringar/styrmedel. Den övergripande slutsats som kan dras av de tre delstudierna som ingått i projektet, samt diskussionen på avslutningsseminariet, är att detta inte är ett etablerat arbetssätt i det svenska förvaltningssystemet. Detta kan förklaras av brist på kompetens, en etablerad misstro, målstyrning samt avsaknad av ett institutionellt ramverk för när och hur denna typ av bredare konsekvensanalyser ska genomföras.

Vi bedömer att detta är ett steg i rätt riktning men ser också att de nationalekonomer som arbetar ute på myndigheter ofta är ensamma eller väldigt få och därmed kan behöva olika former av stöd för att kunna utveckla arbetet med denna typ av, ofta komplexa, analyser på sin myndighet. ; Sustainable development implies that society's limited resources should be used efficiently, taking into account the various impacts on society – social, economic and environmental.

Within the EU a Regulatory Impact Assessment, where a cost-benefit analysis is included, needs to accompany all major regulatory initiatives. According to research and different policy assessment, Sweden lacks an established praxis regarding this type of analysis in the area of environmental policy but also in the field of energy and transport. The purpose of this project is to investigate how Sweden uses this type of information in the negotiations that take place within the EU regarding policy proposals but also investigate the reasons for use or non-use.

The overall conclusion that can be drawn from the three sub-studies included in the project, as well as the discussion at the closing seminar, is that this is not an established way of working in the Swedish government system. This can be explained by lack of competence, an established mistrust, management by objectives and lack of an institutional framework for when and how this type of broader impact assessment is to be conducted. At the closing seminar, the Swedish Environmental Protection Agency presented that it is now working on a guide to help officials to analyze at an early stage whether there is a need for regulation by society, to initiate the work by asking the question "What is the problem?". We think that this is a step in the right direction, but we also see that the economists working out in government are often alone or very few and may therefore need different forms of support to develop the work on this kind of, often complex, analysis.

Social sustainability in urban places is undervalued in urban planning due to the intangible nature of the concept. By valuing lived experiences of place, this research connects social and environmental sustainability pillars to support planning for socioenvironmental justice from a citizen's perspective. The quality of the urban outdoor environment is explored in relation to safety and individual and collective efficacy for social wellbeing which contextualises the role of urban green space. This study suggests socio-environmental sustainability is related at an individual and collective level. Safe social environments can support place attachment processes and safe green spaces can support self-regulation of emotions that influences behaviours. The urban outdoors can be viewed as a social learning environment. An inductive interpretative phenomenological analysis (IPA) led enquiry has been conducted which suggests urban places for social wellbeing can be explained by a framework that integrates social and environmental psychology and spatial politics theories. This study suggests that place attachment is at the heart of dynamic social environments and influences social learning behaviours through vicarious learning and the manifestation of social spaces as framed by Scannell and Gifford's Tripartite Framework of Place Attachment, Bandura's Social Cognitive Theory and Lefebvre's Theory of Produced Social Space. Designing for socio-environmental justice is associated with understanding human irrationality due to poor social and environmental quality. This research suggests the right to feeling safe and the quality of the urban environment, including safe green spaces, becomes an issue for the operation of democracy and facilitating self and collective efficacy, by recognising the invisible bricks that form urban places for social wellbeing.

The purpose of IPBES assessments is to depict how the natural world and human societies interact with each other on a conceptual level. Habitat degradataion, eutrophication, fishing and climate change are examples of drivers of change that affect Nordic coastal habitats. Policy and governance are principal indirect drivers that both could lead to decline and deteriorations, as well as improvements and recoveries environments. Climate change will affect Nordic marine biodiversity profoundly in the future by changes in, for example, bio-chemical cycles and in the distribution of biodiversity. Such changes might lead to increased oxygen depletion in many areas, leakage of nutrients, changed thropic structures and spread of pathogens. It is therefore of paramount importance that effective governance is developed to mitigate impacts on nature's contributions to people (NCP) and to build sustainability and strategies for sustainability. Less overfishing, less euthropication, fewer pollutants and better land-use and nature protection are measures that will improve the overall resilience of Nordic coastal environments.

The thesis concentrates on Hofors and a local trade union environment between 1917 and 1946, where important parts of the trade union's power were held by parties to the left of the social democrats. The overall aim is to problemize and discuss the issue of what characterised and made possible this deviation from the usual picture of a trade union movement dominated by social democracy. What characterised the conditions in such a local trade union environment and to what extent can local norms and political culture be linked to the conditions and the development in the trade union movement in Hofors? The factors behind the radicalism in Hofors can be found in the local union and political context. The investigation points out the following main reasons: the left-wing local council of the Social Democratic Party and its successors' organisational lead, the local labour council's working method being close to what has been considered "social democratic", their representatives being highly trusted in the local community, and the growth of a local radical tradition. The political culture and the norms that gradually developed were based on a left-wing social democratic tradition. The local council of the Social Democratic Party that left the party in 1917 to join the left-wing social democratic faction was the same local council, despite their names and change of parties in the 1920s and 1930s. It became the local labour movement's bearer of traditions and represented the continuity in the local trade union environment, which contributed to the leftwing socialist project being long-lived in Hofors. The central aspects were the trade union work and the practical-concrete tradition that developed. Primarily through successful trade union work, the local labour council and its trade union representatives gained strong and long-term support from a large proportion of the local trade union movement's members and the population of Hofors. Against this background it may be stated that, even though it was often impossible for the parties to the left of social democracy to maintain a local trade union and political power position that was stronger than that of the social democrats for a lengthy period of time, it was not entirely impossible. It may also be stated that for the trade union member as such, a communist or socialist party affiliation was not a real obstacle in the election of shop stewards. Their focus was primarily put on the would-be representatives' personal qualities and ability to live up to the demands and expectations placed on them by the members, and not so much on their ideological persuasion.

The purpose of this thesis is to map and assess the organisational and ideological development of the European Liberal Democrat and Reform party, the ELDR. More specifically, it seeks to analyse the degree of integration between the members of the ELDR over time, to identify factors that may or may not generate integration, to relate the development of the ELDR to earlier research about European parties, and finally to contribute to the ongoing debate about whether or not the traditional national party families are about to establish parties at the European level. The thesis is based on the assumption that parties adapt to their environment, in this case, the system of multi-level governance that characterises the European Union. As the European parties are composed of national parties, they are also dependent on the member parties' opportunities and motives for cooperation. If there is integration, we can, however, not only expect the European parties to adapt to their environment. As they become independent actors, they may also influence their environment. In other words, we can anticipate interaction between the European and national levels that leads to mutual adaptation, or Europeanisation. To be able to capture the interaction between the two levels, theories from international relations and comparative politics are combined. Based on interviews, participant observation, documentary research and content analysis of European election manifestos, the analyses shows that the members of the ELDR have over time reached a rather advanced level of integration, both organisationally and ideologically. Although it is possible to identify constraining factors to this development, the ELDR has, at least from what is known from literature, reached about the same level of development as the two other European parties, the Christian democratic EPP and the Social democratic PES. The internal integration of the ELDR is the outcome of a successive transfer of power from the member parties to the ELDR. By now, the ELDR can therefore be defined as a rather independent actor and as a type of party at the European level. This type of party is, however, not comparable to national parties. It is instead adapted to the institutional structure of the European Union, with, at least partly, a different organisation and different functions from those of national parties. ; digitalisering@umu

The European Union (EU) recently implemented the Environmental Liability Directive (ELD), requiring that environmental damage be restored so that the affected environment returns to (or toward) its baseline condition and the public is compensated for the initial damage and the losses during the time it takes for the environment to recover (interim losses). Equivalency Analysis (EA) represents a method for scaling environmental compensation to offset interim losses. Ensuring appropriate compensation for resource loss requires a merging of ecological measurement with the theories of welfare economics. This thesis explores some of the issues in scaling resource-based compensation in three papers. Paper I is a quantitative application of the EA method to compensate for sea eagle mortality from wind turbine collisions. It is co-authored with a biologist and proposes a new and innovative compensatory measure based on electrocution prevention on power lines. Paper II is written for an ecological readership and communicates fundamental economic assumptions in a way that might be helpful for cross-discipline collaboration. The main contribution is to clarify that the underlying goal of environmental compensation should be "no net loss of welfare." Paper III scrutinizes the conventional EA method from a social efficiency perspective, suggesting that the focus on equity for the victim may preclude a socially optimal compensatory outcome. The overarching conclusion is that EA fails to inform policy makers of the inescapable environmental trade-offs that arise in compensating environmental losses.

Environmental organizations play an important role in mainstream debates on nature and in shaping our environments. At a time when environmental NGOs are turning to questions of gender-equality and ethnic diversity, we analyze their possibilities to do so. We argue that attempts at ethnic and cultural diversity in environmental organizations cannot be understood without insight into the conceptualizations of nature and the environment that underpin thinking within the organization. Serious attempts at diversity entail confronting some of the core values on nature-cultures driving the organization as well as understanding the dimensions of power such as class, gender, and race that structure its practices. We study what nature means for one such organization, the Swedish Society for Nature Conservation, and the ways in which thinking about nature dictates organizational practice and sets the boundaries of their work with diversity in their projects on outdoor recreation. We base our analysis on official documents and interviews, analyze how ''diversity'' and ''gender-equality'' are represented in the material and reflect on the interconnections as well as the different trajectories taken by the two issues. Our study shows that the organization's understanding of nature is a central and yet undiscussed determinant of their work with diversity that closes down as much as it opens up the space for greater inclusion of minorities. We argue that for environmental organizations wanting to diversity membership, a discussion of what nature means for people and their relationships to each other and nature is vital to any such efforts.

In this chapter, essential ecological and societal aspects of the Nordic coastal environment are highlighted. These show that local communities and stakeholders need to be more involved in decision-making because their needs and their ecological knowledge are essentialto this process. This also relates to Aichi targets 14, 15, 16 and 18 (see Lucas et al., 2015). There is the need to improve the monitoring of all types of NCP or ecosystem services and to critically review existing indicators that may be used to track the development of biodiversity and NCP. Only by actively analysing data and creating syntheses, is it possible to understand changes in the ecosystem linking biodiversity and NCP.

Institutional logics create order and stability. They organize interaction and prescribe how we should behave towards each other. Such logics have generally been regarded as exclusive, in the sense that an organizational field is always guided by a single institutional logic. If there are two or more institutional logics in one setting at the same time this will create conflicting demands and contradictions. So how do organizations and individuals that act in these settings, where different institutional logics do meet, cope with the conflicting demands? This question is researched by studying actors who organize partnerships between corporations and non-profit organizations. Institutional logics have typically been studied at field level. My study follows a more recent literature strand focusing on individuals and their way of coping with conflicting institutional logics. In this thesis, interviews, text analysis and observations are used. The interviews were conducted with CSR managers of corporations, managers of corporate partners at non-profit organizations, CSR consultants, and project managers of intermediary organizations. These actors are working in an environment where conflicting institutional logics are played out. Using a narrative approach it is shown how these actors are aware of their institutional environment and its conflicts which requires them to constantly act as translators. The study shows that the actors organize an interplay between a market-logic and a social-welfare logic by bringing together the logics and establishing limits to what extent logics can be mixed. Thus, the actors can be understood as bilingual, rather than hybrids. Furthermore, it is argued that a narrative approach provides the possibility to understand institutional logics in empirical contexts as more present and visible than they are usually considered to be. The study concludes that bilingual actors balance conflicting demands and negotiate requirements set by institutional logics in their day-to-day work. Settings where institutional logics meet can hence be understood as both a contradiction and an ongoing interplay.

The objective of this report was to study how some countries work in practice with the ecosystem service concept. The approach chosen was rather broad focusing on green infrastructure planning, development or management including urban, rural and coastal areas at all scales. The countries chosen were Great Britain, Germany and Norway, since this allowed to read documents in the national languages. For each country also the national ecosystem service assessments based in the EU biodiversity strategy to 2020 have been investigated. It can be concluded that the three countries have come differently far in their work to implement the ecosystem service concept in planning practice. Great Britain can be seen as most advanced with comprehensive assessments at national level and regional and local examples which take their point of departure in the ecosystem service concept. The green structure plans of Birmingham and Manchester as well as the work in the South Downs can be pointed out as inspiring examples. In Germany comprehensive assessments at national levels have been carried out in later years. The practical examples found have often a research connection or had not their starting point in the ecosystem services concept, but have been interpreted within its context afterwards. This might be seen as an indication that the implementation of the ecosystem service concept in Germany at regional and local level outside research environments is still limited. Norway has comparable work ongoing regarding the implementation of the ecosystem service concept despite not being member of the EU and thus not been obliged to follow the EU biodiversity strategy. National assessments of ecosystem services have been carried out, partly in cooperation with the other Nordic countries. The number of research environments working with the ecosystem service concept is of course smaller than in the other countries considered here. However, in Norway as in Sweden, there is an ambition to implement the ecosystem service concept within municipal planning. Interestingly, in Norway the ecosystem service concept has also been integrated in the environmental impact assessment legislation. Studying these three countries' approach to work with the ecosystem service concept in practice in relation to green infrastructure has given interesting first insights. To get a more comprehensive and detailed overview further studies would be needed, preferably including site visits and personal contact with research institutes leading in the field as well as meeting local and regional authorities.

This dissertation studies the development of the environmental issue from a discursive perspective. Through an analysis of views on nature and the environment in several NGOs and main political organs, the dissertation tries to explain how a certain view became hegemonic. The analysis pertains to the period between the publication of Silent Spring in 1962 and the introduction of the concept sustainable development by the UN in 1987. From a realistic starting point and with critical discourse analysis (CDA) as its method, the dissertation aims to identify causal powers and mechanisms that have generated and institutionalized the environmental discourse. An analytical model is developed and applied on three levels; a sociolinguistic, institutional, and macrosocial level; which also reflect the methodological progression of the study from description to explanation. The result shows that the discursive practice was hegemonized by a Western view promoting economic growth. This discourse gradually gained ground at the expense of an anti-systemic discourse which posited structural societal changes as the answer to environmental problems. Mechanisms such as the exclusion of some views and actors from common discursive practices were crucial for the process of homogenizing the discourse and developing consensus. Through incorporating that part of the environmental movement which did not fight the dominant economic and political system, the UN turned it into support for its own project, which is part of the process of hegemony. At the same time the environmental objectives of the hegemonic discourse were established in the institutional spheres. The institutionalization of the environmental issue changed the focus from social critique to a question of development and technology, something which helped displace the original critical and partially anti-systemic character of environmental discourse. Through turning the critical and negative account of the situation into a more harmonious and hopeful vision, for instance in terms of sustainable development, a foundation was laid for the later development of ecological modernization. When the hegemonic discourse invested the concept of sustainable development with emphases on progress and economic growth, it encapsulated the environmental issue within the framework of the prevailing social system. ; With summary in English and Spanish/Con resumen en inglés y en español
