The purpose of this study was to develop a compilation of knowledge about the risk factors of stress and fatigue, and their importance for injuries in agriculture as a basis for preventive measures. The knowledge compilation was based on an extensive literature review and partly on analysis of previously conducted interviews with farmers who suffered accidents. In the literature review, both national and international studies were investigated with regard to the mentioned risk factors for injuries. Also examples of preventive measures applied to farmers were obtained. Documentation of projects was also sought through various industry magazines and websites. The Department of AEM possesses extensive data on injuries in agriculture and forestry in 2004 and 2013. From this data, 460 short stories were analyzed of what happened at the time of the injury and the cause of the injury in 2004. From the 2013 study, 242 stories were analyzed regarding the injury, but also about the measures taken by the farmer to prevent injuries. In addition, 75 band-recorded interviews were analyzed with the affected farmers with further information. In particular, the stories that indicated stress and fatigue as a cause of the injury were studied. The studies of occupational injuries in the Swedish agriculture show that injuries have decreased in absolute terms over the past 10 years. Taking into account the reduced labor requirements in agriculture or decrease in the number of farms in the same period, the number of injuries has not decreased. Farmers are exposed to various risks of injuries at work, such as handling animals (e.g. crushed or trampled by the animals), large machinery and vehicles (such as stuck in the machine, tractor injury) and in construction and repair work (e.g. fall from ladder). In addition to these hazardous conditions, the farmer is also exposed to a variety of stressors by e.g. heavy workload, time pressure, mechanical and technical failures, disease attacks, financial worries, dependent on the weather, government regulations, bureaucracy, working alone and family problems. The literature review showed that farmers who experienced a lot of stress were more likely to experience an accident in their work. Many farmers suffer from fatigue, sleep disorders and insomnia that is related to the high workload and stress they are exposed to, which can affect the ability to make decisions for dangerous situations and injuries as a result. Many of the farmers who suffered injuries in agriculture in Sweden also indicated stress, fatigue, sleepiness, carelessness or negligence as cause of the injuries. There are a lot of fact sheets and brochures with advice to farmers on how to deal with stress and fatigue by example to take breaks, exercise regularly, eat healthy foods and avoid alcohol. Several interventions and programs have been implemented with regard to the prevention of occupational injuries in agriculture. Some studies showed positive results, while most others gave very limited evidence that interventions were effective in reducing agricultural injuries. There is a need for more accurate evaluations of intervention programs for safety in agriculture.

Is there a common notion amongst the political and military leadership in Sweden on how to defend the country? Several events in the arena of international politics during the 20th century argue for the importance of coherence between political and military thinking. Different focus during peacetime has subsequently caused fatal consequences in times of war. This thesis studies a less obvious case: Sweden, a small-state, during the 1990's in the aftermath of the Cold War. In the effort of identifying inconsistency between the political and military level the study deals with a more comprehensive issue for any democratic society: How shall the elected political leadership exercise control over an authority (subordinated the government and) with deeply rooted professional values and with authority vested in it of crucial importance for national survival? Although several of government authorities play key roles in this respect the Armed Forces stands out to be the single most important entity. The thesis approaches the problem by studying one measure of control: the defence doctrine. The doctrine is analysed by studying various documents provided by the political decisionsprocess and with interviews involving a significant number of actors in the politico-military leaderships. The purpose has been to identify whether there is any inconsistency prevailing in the perception of values to be protected by the Armed Forces in case or war, what poses threat to these values and finally how to counter the threats. Hence, the political and military views on defence doctrine are examined. The last element of the doctrine, how to deal with the perceived threats, is embodied in the strategy for countering threats. Comparative studies involving Norway and Finland have been made to provide relevant references for the findings and provide a framework for elaboration on the differences between political and military priorities encapsulated in the research hypothesis. In addition, the research hypothesis involved the assumption that technical, tactical and operational decisions would serve as explanations for any inconsistency between military and political priorities. Piecemealed low-level decisions were assumed to unintentionally diverge bottom- up perceptions and create tensions if the politico-military interaction is not fully functional or if the politicians do not fully comprehend the implications of their decisions. The empirical findings suggest differences in the consistency of the politico-military leadership when comparing Sweden with Norway and Finland. For Sweden, the findings suggest a relative good politico-military adherence regarding values and threat perceptions. However there is a disparity in the views on what strategy to adopt and the military leadership has a more offensive mindset than the political leadership. The empirical data has primarily been collected from processes. To provide a better explanation for the findings the structure of security policymaking has been adopted in a new conceptual model based on Edward Luttwak's 'vertical dimension'.

It is rather often assumed that Swedish foreign policy debate is largely characterized by consensus and that foreign policy goals often are material (for example security or economic welfare). Despite this, it is possible to identify disagreement among political parties about ideological goals – i.e. the promotion of values – in Swedish foreign policy debates. This raises questions about the nature and importance of these ideological goals in such debates. To study this closer I investigate foreign policy debates about the military conflicts in Vietnam and Iraq. The purpose of the dissertation is to describe and explain the content and relative importance of the ideological goals expressed by Swedish parliamentary parties in both party and public arenas. Four parties are included in the study: the Left, the Social Democrats, the Liberals and the Conservatives. The theoretical framework is made up of two main parts. First, I develop a classification scheme to identify and sort the goals found in the empirical material. This scheme includes four goal types: ideological, security, economic, and other. Second, insights from literatures on foreign policy and the behaviour of political parties are used to analyze the content and importance of ideological goals. The research design used in the dissertation is comparative case studies. The empirical material is composed of documents from the internal party arena (meeting minutes, congress material, etc), the parliamentary arena (debate material) and the official arena (press material). The material has been analyzed mainly qualitatively with the help of ideational and argument analysis. In order to estimate the relative importance of ideological goals quantitative content analysis has also been used. As regards the content of ideological goals during debates about Vietnam, the empirical results show all parties discussed the promotion of humanity, democracy and states' rights to national independence. In the Iraq conflict, all parties expressed goals about humanity, human rights, internal security/safety, democracy and states' rights to national independence. Beyond these goals, individual or a few parties also expressed other ideological goals. However, a central result is that the parties have linked the ideological goals – which they often agree about – to different ways of reasoning. The empirical analysis also revealed that ideological goals have generally been more important than other types of goals (with the exception of the Conservative Party in the debate about Vietnam). Regarding developments over time, the importance of ideological goals was unchanged for the Social Democrats and the Liberal Party. For the Left there was a slight decrease, and for the Conservatives a significant increase. The overall conclusion about what explains the content and importance of ideological goals in the foreign policy debates studied here is that explanations at the systemic level are inadequate. Variables like the international political structure (polarity) and institutional mechanisms in the EU and the EU's Common Foreign and Security Policy had little explanatory power. Instead, explanations like type of foreign policy issue, party ideology and party strategy were more useful. Differences in parties' fundamental ideological views were also discussed as an important source of difference as regards the positions and arguments that expressed ideological goals.

This study in contemporary history describes the transformation of the public sphere in Sweden during the period 1969-1999, and analyses the role of information technology and politics in the process. The overall aim of the study is to explain how, and why, the public sphere in Jürgen Habermas sense has deteriorated during a period of rapid technological and political change, when increasing attention has been given to information technology as a new tool for improving democracy and empowering citizens. Theoretical inspiration is drawn from two perspectives within the modern history of technology and sociology of technology; the LTS (Large Technical Systems) and STS (Science, Technology and Society) approaches, as well as from the regime theory concept within political science. This multidisciplinary framework provides the theoretical basis for the study, including terms as socio-technical systems, system builder, technification, interpretative flexibility, stabilization, closing and regime change. In addition, the analysis draws upon previous research in economic history, where focus often has been on the important role of institutions. The term path dependence is central in this tradition. The starting point for the study is the process of a mutual legitimization between citizens and political actors that traditionally has taken place within the public sphere. In return for citizens support and trust, political actors have granted format rights to the public space. Two aspects of this interdependence are addressed: Freedom of speech and citizen's access to public information, and their access to arenas where an exchange of political ideas and opinions is taking place. In the study, the former is a question of the legal system and the limits to freedom of speech in new medias such as the Internet, while the latter concerns citizen's technical means and possibilities to connect to electronic networks. Research interest is concentrated on the formal political system, focusing both actors and structural factors such as technological development, media convergence, ideological change and international integration in the transformation process. Four case studies of institutional changes during formative moments, within what is defined as the legal and the technical infrastructures, are conducted and represent the empirical base of the thesis. The case studies are centered on Swedish governmental commissions, on the government itself and on proceedings in the parliament, and concerns formation and transformation of computer law, as well as the deregulation and privatization of the technical infrastructure. In the latter process Televerket (Swedish Telecom) has been an influential promoter of competition and institutional separation between tele- and data communications, representing a major regime change in favour of market relations in the technical infrastructure. In the area of computer law, the Swedish regime dominated by SCB (Statistics Sweden) was incorporated into a joint European data protection regime, resulting in limitations of freedom of speech on the Internet. These regime changes have also transformed the role of the state, constituting a "net watchers state". Another important finding is that promotion of democracy and improvement of access to the public sphere, never was on the agenda in the political transformation processes studied, although a parallel discourse on democracy and information technology existed throughout the period studied.

This study starts out with the hypothesis that the integration process in Europe is connected to cross-border régionalisation, a process which supports the institutionalization of subnational cross-border cooperation - region-building. Cross-border régionalisation is characterized by the decentralisation of vertical links and enhanced opportunities for horizontal links across state borders. In addition, political integration is expected to have some impact on the cross-border institutional forms that emerge at the subnational level. Three different approaches are utilized in order to establish the empirical connection between political integration and region-building. These are: an analysis of the factors which determine the general pattern of cross-border cooperation in Europe, an analysis of the policy network related to the regional and structural policies of the European Union (EU), and case studies of cooperation in the heartland of Europe, the Regio Basiliensis along the external border of the EU, and the EUREGIO along one of the internal borders. Two institutional factors are found to have a significant impact on the number of subnational cross-border cooperations, EU-membership and centrality. Federal constitution was shown not to be significant. It is suggested that the interaction between actors at different politico- administrative levels creates network relations, which typically bring both private and public actors together. More precisely, region-building is described as the outcome of the interaction which takes place between actors. A closer examination of the emerging policy network shows that community initiatives, the Interreg-programme in particular, improve the prospects for multi­level interaction. The EU plays a crucial role in providing the incentives for cooperation by increasing resource dependency and by establishing direct ties between the European Commission and a large number of subnational actors through partnerships. It appears as if the Commission wishes to demonstrate its capacity to deal with problems relevant to individual citizens. By, in part, bypassing central governments, it seems to increase its own importance vis- à-vis member states. The modus vivendi of cross-border region-building and régionalisation is the degree to which institutional actors at different levels share the same objectives. As shown by the case studies, there is a common interest in cross-border cooperation up to the point were public statues are introduced. Interests seem to coincide as long as the structures and contents of cross-border cooperation do not ultimately challenge the authority of state institutions. Therefore, it is not surprising that it seems impossible to give cross-border regions any rights under international law. Functional cooperation, rather than regionalist manifestations of cultural or political unity across borders, constitutes the backbone of region-building. Activities transcending borders are less controversial than those that may contribute to the establishment of new borders. It is concluded that region-building is a process which is embedded in the institutionalization of a multi-level interaction pattern. More favourable multilevel relations have been achieved through the transfer of some authority to the supranational level. This is the main reason why traditional integration theory fails to explain why there is a connection between political integration and cross-border cooperation. ; digitalisering@umu

This dissertation analyzes the concept of democracy as it was used in the official rhetoric of the Swedish SocialDemocratic Party (SAP ) between 1919 and 1939. Theoretically, the dissertation relies on German Begriffsgeschichte, as put forward by Reinhart Koselleck, and Michael Freeden's theory of ideologies. Together, by supplementing each other, these theories offer a perspective in which concepts are thought of as structures that are under contestation and change due to socio-political circumstances. However, the formulation of this change takes place in relation to the linguistic praxis of each time-period, and renegotiates the relative constraints of established relations between concepts in language. The analysis shows that the profound changes in society provided impetus for a continuous renegotiation of meanings, allowing concepts to retain their explanatory power under changing circumstances, at the same time the SAP needed new ways to express what kind of society the party strived to realize. The SAP had been one of the leading forces in the struggle for universal suffrage, and when the bill, giving universal suffrage to men andwomen, was passed in the Parliament 1919 this meant a temporary cessation to a long and intensive political debate. However, the SAP did not consider the introduction of suffrage reform as the end of full societal democratization. Rather than seeing the reform as a terminal point, the SAP saw it as the starting point for the struggle for full democracy. The SAP did not limit itself to only one concept of democracy but instead used a number of composite concepts, such as political democracy and economic democracy. The use of composite concepts can be understood as a changing temporalization of democracy. Since parliamentarism and suffrage were seen as central components in democracy, the realization of these institutions meant that the concept of democracy lost its future dimension. Thus, the usage of composite concepts should be seen as a re-temporalization of democracy. The composite concepts pointed forward in time, toward political goals that the SAP envisaged realizing in the future. Concepts should not be thought of as having cores but rather, as suggested by Freeden, ineliminable features. An ineliminable feature is not of logical nature but has a strong cultural adjacency. By analyzing the ineliminable components of the concepts of democracy that the SAP used, it is possible to discuss whether the composite concepts should be understood as subsets of a whole or as separate concepts. The analysis shows that the composite concepts that the SAP used during the first half of the 1920s shared a number of ineliminable features, but that the commonality of these features started to disintegrate during the latter half of the decade, leading to a rather diversive concept of democracy. During the 1930s the disintegration ceased as the party was faced with new circumstances, for example the growing threat of international war and national clashes between different social groups. There has always been a close relation between language and society. However, the relationship does not follow a simple and clear-cut logic but a complex mixture of various factors at different levels, both within language itself and of society. When society develops, language also has to change if the ongoing process is to be understood. As this study shows, new circumstances require new argumentsand thus revised concepts.

The population of the European eel Anguilla anguilla (L.) is in severe decline. In 2007, the European Union decided on a Regulation establishing measures for the recovery of the stock of European eel, obliging its Member States to implement a national Eel Management Plan by 2009. According to this Regulation, Member States will report to the Commission by July 2012, on the implementation of their Eel Management Plans and the progress achieved in protection and restoration. The current report provides an assessment of the eel stock in Sweden as of spring 2012, intending to feed into the coming Swedish post-evaluation reporting. In this report, the impacts on the stock are assessed - of fishing, restocking and of the mortality related to hydropower generation. Other anthropogenic actions, (climate change, pollution, spread of parasites, disruption of migration by transport, etc) probably have an impact on the stock too, but these factors are hardly quantified and no management targets have been set. For that reason, and because these factors were not included in the EU Eel Regulation, these other factors were excluded from this technical evaluation. In this report, focus is on the quantification of the biomass of silver eel escaping (actual, potential and pristine) and the mortality endured by those eels during their lifetime. The assessment is broken down on a regional basis, with different impacts dominating in different areas. For the yellow eel fishery on the West Coast, the assessment presented in the Eel Management Plan is extrapolated to most recent years. Since 2009, the fishery has been restricted severely, and as of spring 2012, it has been closed. In the coming years, this reduction in fishing mortality will lead to a recovery of the West Coast stock to the best possible status given the depleted state of the whole international stock. For the stock in inland waters, a new assessment is presented, in which the dominant contribution from past restocking is put central. Recent changes (increased quantities, shift to west-ward flowing rivers) will have a delayed effect over the coming 10-20 years. The escapement biomass is expected to decrease until 2020 and then to restore to its current (low) value. Assuming that current conditions (2011) are continued, the impact of the fishery will slowly decline, while the impact of hydropower generation will stabilise/increase, at least until 2030. For the East Coast fishery on silver eel, a new assessment indicates a low mortality on a very large stock of silver eel derived from all over the Baltic. Recent restrictions have reduced the East Coast fishery. Protective actions in the whole Baltic (and their delayed effects) will determine the future trend in the East Coast fishery. Comparing the overall status of the national Swedish eel stock to the management targets, it is concluded that 1. Criteria of the Swedish Eel Management Plan have been fulfilled almost exactly; 2. Biomass escaping is about one-fourth of pristine escapement, below the minimum target of 40% set in the EU Regulation; and 3. The 2011 anthropogenic impacts are about half the allowable maximum (according to the ICES/WGEEL post-evaluation framework, at one-fourth of pristine escapement). Following the current closure of the West Coast fishery, the impacts will reduce to one-quarter of that allowable maximum.

Den här avhandlingen undersöker utvecklingen av en elektronisk förvaltning ur ett legitimitetsperspektiv. Det övergripande syftet är att analysera den reella och potentiella förändring som e-förvaltning innebär för den offentliga förvaltningens legitimitetsgrunder, både i form av hur e-förvaltning har formulerats som idé, och hur det konkret har gått till när e-förvaltning har implementerats i praktiken. Avhandlingen består av fem artiklar som undersöker olika aspekter av syftet, från idéerna bakom e-förvaltning på internationell nivå, till implementeringsprocessen på lokal nivå. Den övergripande analysen använder sig av så kallad pragmatisk institutionalism, samt perspektiv på hur legitimitet skapas och upprättshålls i förvaltningen. En fallstudie av en svensk kommun utgör det huvudsakliga empiriska materialet. Detta material kompletteras med en mindre studie av ytterligare en svensk kommun, samt dokumentstudier av den Europeiska Unionens policy för e-förvaltning. Avhandlingen lyfter fram fyra huvudsakliga slutsatser: (1) e-förvaltningsreformer bidrar till skapandet av en ny praxis, där den praktiska utvecklingen och tillämpningen av IT blir ett allt viktigare inslag i den studerade kommunens organisering och serviceutövning, (2) detta bidrar till en omorganisering av aktörsroller- och förhållanden. Ledande tjänstemän i kommunen övertar den strategiska styrningen av utvecklingsprocessen från lokala politiker, medan kommunens närbyråkrater kringgås genom att medborgaren förväntas ta ett större eget ansvar för interaktionen med förvaltningen, (3) legitimitetsgrunder såsom brukarinflytande och kundanpassning placeras därmed i förgrunden medan den politiska styrningen och bedömningen hamnar i bakgrunden, (4) dessa förändringar tyder på allt starkare inslag av en gör-detsjälv-logik, där legitimitet i genomförandeprocesser främst grundar sig i individens möjlighet till självbetjäning och självförvaltning via elektroniska kanaler. ; This thesis explores the development of an electronic government from a legitimacy perspective. The overarching aim is to analyse the actual and potential processes of change and impacts of e-government on bases of legitimacy within public administration – both with regards to how the ideas behind e-government have been formulated as well as how e-government in practise has been realised. The thesis consists of five articles that examine different aspects of the overarching aim; from the ideas behind e-government on an international level, to the practical implementation process in local government. The overarching analysis uses an institutional perspective and perspectives on the creation and maintenance of legitimacy in public administration. An in-depth case study of a Swedish municipality provides the main empirical material for the analysis. In turn, the material is supplemented with a smaller case study of another Swedish municipality, as well as document studies of the e-government policy of the European Union. The analysis arrives at four overarching conclusions: (1) egovernment reforms contribute to new practises, in which the development and application of IT is becoming increasingly central for the local organisation and the provision of public services, (2) this contributes to a reorganisation of actor roles and relationships. Leading public officials shoulder the strategic steering usually confined to local politicians, whilst street-level bureaucrats are circumvented by citizens since citizens are expected to shoulder greater individual responsibility in their interaction with administrations, (3) in turn, certain bases for legitimacy are placed in the foreground, in particular user influence and customer adaptation, whilst political steering and evaluation are downplayed, (4) these developments point at the emergence of a do-it-yourself-logic, in which legitimacy is mainly based on creating sufficient preconditions for individual selfservices and self-government through the electronic channels of administrations.

Young people's view of nuclear power and democracy since the 1980s: attitude epidemics, path dependencies and technical-political cultural revolution. In the wake of the leftist wave, young people's criticism of the system has diminished, both in terms of criticism of the nuclear-based energy system and of the nature and workings of the political system. Baby-boomers (people born in the 1940s and '50s) in particular have changed their attitude and become less hostile to the establishment. But how did this change in attitudes occur? How has young people's view of technology and democracy changed during the past few decades? Based on data from the SOM Institute gathered between 1987 and 2005, this final report presents the results of one of the two studies conducted in the project "Towards activism or indifference? How Swedish young people view democracy and the environment, science and technology in an international and longitudinal perspective". First a theory and a method are proposed for analyzing what is called in this report "attitude epidemics", referring to the fact that attitudes spread like wildfire or epidemics, leading to what societal researchers call "path dependencies". Then age-versus-generation differences are studied, as well as a large number of other factors, with regard to attitudes to technology, nuclear power and democracy in particular, or the way democracy works in Sweden. Younger people are found to be the most critical of nuclear power, while they are most satisfied with democracy, even though gender, risk perceptions, party affiliation and political positioning are some of the factors that also influence these analyses on the individual level. The "epidemic effect" and path dependencies do not show their strength in these individual analyses, but all the more in the analysis of time series where the computer and IT revolution is found to be very strongly linked to the strong growth in acceptance of nuclear power. Using new communication technologies is somehow associated with a decline in hostility toward technology and nuclear power. But many cause-and-effect relationships in this attitudinal and technical-political "cultural revolution" still remain to be explored. ; I vänstervågens svall har ungdomens systemkritik avklingat, både i bemärkelsen kritik mot det kärnkraftsbaserade energisystemet och mot det politiska systemets väsen och funktionssätt. Främst 1940- och 1950-talisterna har ändrat inställning och blivit mindre systemfientliga. Men hur gick denna förändring i attityder egentligen till? Hur har synen på teknik och demokrati bland ungdomar förändrats senaste årtiondena? Med användning av SOM-institutets data 1987–2005 presenterar denna slutrapport resultat från en av de två delstudierna inom projektet "Mot aktivism eller ointresse? Svenska ungdomars syn på demokrati och teknologi i ett internationellt och longitudinellt perspektiv". Först föreslås teori och metod för att analysera det som i denna rapport kallas "attitydepidemier", att attityder sprider sig lavinartat, och genom dem etablering av vad samhällsforskare kallar "stigberoenden". Därefter studeras ålders- kontra generationsskillnader, liksom ett stort antal andra faktorer, med avseende på attityder till framför allt tekniken kärnkraft och demokrati eller demokratins funktionssätt i Sverige. Yngre visar sig vara de mest kritiska mot kärnkraften men de mest nöjda med demokratin, även om kön, riskuppfattningar, partianhängarskap och politisk positionering är några av de faktorer som också spelar roll i dessa analyser på individnivå. "Epidemieffekten" och stigberoenden visar inte sin styrka i dessa individanalyser, men desto mer i analysen av tidsserier där dator- och IT-revolutionen visar sig mycket starkt förbunden med den starka tillväxten i kärnkraftsacceptans. Att använda nya kommunikationstekniker hänger på något sätt samman med minskning av teknikfientlighet även till kärnkraften. Men många orsakssamband i denna attitydmässiga och teknisk-politiska "kulturrevolution" är fortfarande outforskade. ; "Mot aktivism eller ointresse?

There is no doubt now that energy is fundamental to our development. Global energy trends such as higher energy demand and prices, big differences across regions, structural changes in an oil and gas industry increasingly dominated by national companies, the prospect of irreversible climate change, as well as demand for energy security all highlight the need for a rapid transition to a low-carbon, efficient and environmentally benign energy system. The search for energy alternatives involving locally available and renewable resources is one of the main concerns of governments, scientists and business people worldwide. As researchers tackle problems according to global trends, an overwhelming body of research focusing on bioenergy in relation to other types of renewable energy might illustrate the role bioenergy has as the most important renewable energy source for the near and medium-term future. Thus, analyzing the amount of existing research, we found that about 50% (4,911 records) of 9,724 renewable energy records available were bioenergy records. We also found that publications on each of the four main sources of biomass (agriculture, forest, waste and other) represent about one quarter of the 4,911 bioenergy records retrieved. Biomass – the fourth largest energy source after coal, oil and natural gas - is the largest and most important renewable energy option at present and can be used to produce different forms of energy. As a result, it is, together with the other renewable energy options, capable of providing all the energy services required in a modern society, both locally and in most parts of the world. Renewability and versatility are, among many other aspects, important advantages of biomass as an energy source. Moreover, compared to other renewables, biomass resources are common and widespread across the globe. The sustainability potential of global biomass for energy is widely recognized. For example, the annual global primary production of biomass is equivalent to the 4,500 EJ of solar energy captured each year. About 5% of this energy, or 225 EJ, should cover almost 50% of the world's total primary energy demand at present. These 225 EJ are in line with other estimates which assume a sustainable annual bioenergy market of 270 EJ. However, the 50 EJ biomass contributed to global primary energy demand of 470 EJ in 2007, mainly in the form of traditional non-commercial biomass, is only 10% of the global primary energy demand. The potential for energy from biomass depends in part on land availability. Currently, the amount of land devoted to growing energy crops for biomass fuels is only 0.19% of the world's total land area and only 0.5-1.7% of global agricultural land. Although the large potential of algae as a resource of biomass for energy is not taken into consideration in this report, there are results that demonstrate that algae can, in principle, be used as a renewable energy source. From all of these perspectives, the evidence gathered by the report leads to a simple conclusion: Biomass potential for energy production is promising. In most cases, shifting the energy mix from fossil fuels to renewables can now be done using existing technology. Investors in many cases have a reasonably short pay-back because of good availability of lowcost biomass fuels. The latter is of course dependant on local incentives, however. Overall, the future of bioenergy is also to a large extent determined by policy. Thus, an annual bioenergy supply covering global energy demand in 2050, superseding 1,000 EJ, should be possible with sufficient political support. Global production of biomass and biofuel is growing rapidly due to the increasing price of fossil fuels, growing environmental concerns, and considerations regarding the security and diversification of energy supply. There are many scenarios that predict a high potential for biomass in the future. There have also been many studies performed in recent decades to estimate the future demand and supply of bioenergy. Overall, the world's bioenergy potential seems to be large enough to meet the global energy demand in 2050. The current stock of standing forest is a large reservoir of bioenergy and in line with the theoretical potential of biomass energy. However, most of the research studies on biomass potentials ignore existing studies on demand and supply of wood, despite the extensive literature and data on the subject. Taking into account data from a variety of international sources, rough estimates of the energy production potential of woody biomass from forestry show that, in theory, the demand for wood fuel and industrial roundwood in 2050 can be met, without further deforestation, although regional shortages may occur. However, the shift in the energy mix requires much more investment in infrastructure, equipment and in some cases R&D. Moreover, a prerequisite for achieving bioenergy's substantially high potential in all regions is replacing current inefficient and low-intensive management systems with best practices and technologies.

Knowledge and valuation of ecosystem services are important components for reaching the governmental goals for improving the natural environments. Recreational fishing has more than one million practitioners nationwide.Knowledge about the fishers and their catches increases the ability to assess whether the ecosystem services are retained. In addition, it gives means for evaluating the actions for the conservation, restoration and sustainable use of oceans, lakes and rivers. Knowledge of recreational fishing is also needed in order to follow up the details in its environmental objectives relating to outdoor recreation, tourism industry and the governmental goals in the open-air policy. The EU's common fisheries policy, the Swedish environmental policy and Swedish fisheries policy all emphasize that ecosystem-based management should be implemented. Thus, there are needs for knowledge of the ecosystems which are exploited by humans. Fish populations are important components of aquatic ecosystems, and are affected by the surrounding environment, while they themselves affect the structures of the aquatic food-webs. Fishes often have regulatory functions in the ecosystems, and thereby contribute to valuable ecosystem services in addition to the more obvious services as providing food and recreation for humans. Mostly issues regarding the impacts of fishing-related activities on fish populations have been focused on commercial fishing. A widespread and intensive commercial fishing may lead to the depletion of stocks or, at worst, a collapse of the fish populations; the fish population reaching such low levels that recovery may be difficult. In recent years the knowledge of the impact of recreational fishing on aquatic systems has increased, but still the effects of recreational fishing on ecosystem are relatively poorly studied, compared to commercial fisheries. For many, it may be difficult to accept that recreational fishing may affect fish populations; each fisher/angler favour just their own fisheries without bearing in mind that although the small influence from each individual fisherman may be small, it will be significant when many fishermen harvest from the same stock. Recreational fishing and its effects on the aquatic ecosystems are often neglected in fisheries science, mainly due to the lack of data to estimate recreational fishing harvest with a sufficient resolution to calculate the effort and landings of recreational fisheries. In this report, we try to give an overall picture of the fish species needing increased knowledge in order to get an estimate of harvest in recreational fisheries and thereby the effect on fish populations. Furthermore, we also try to give a picture of international studies and finally to give examples of methods concerning how and to what extent one may conduct studies in Sweden. Our proposal is largely based on combining different surveys in specific areas that we believe can be used to scale-up the results. We suggest data collation of recreational fishing is concentrated to areas with public waters, because in other water bodies the land owner has sovereignty under the law. The focus areas we point out are those already having some data collection, both in terms of recreational fishing and environmental monitoring / stock assessment and where there are non-fishing protective areas nearby. Collection of data should not be made in all areas at every year; three areas are suggested to become intensive areas (data collection every year) and the remaining areas data collection will take place every three years - on a rolling schedule. The sampling methods we recommend are national survey (i.e. mail and telephone surveys), recording of catches in fishing tourism, voluntary catch registration of individual anglers, collection of data from fishing competitions, on-site inventory of fishing effort (e.g. count fetter and trailers), inventory of catch per effort (e.g. by creel-surveys) and fish tagging studies. For the west coast we propose one focus area, Älgöfjorden. At the coasts of Bohuslän County and the northern part of Halland County the fishing pressure is high for lobster and crab and therefore a focus area should be established in this area. We suggest that data are collected by on-site visits for inventorying fishing effort (counting numbers of pots / buoys / fishing people), combined with catch registration can return an estimates on catch per effort, and this can then be applied to a larger area. Another potential focus area is the area around Torhamn (Blekinge) which, for example, is popular area recreational fishing for pike. Torhamn is one of three national reference areas for coastal fish monitoring on the East Coast and has been monitored since 2002. It is also desirable to study aspects of fishing mortality in recreational fisheries. To our knowledge, there are no national studies that have explored the effects of catch-and-release in natural environments over long periods of time. The Bråviken Bay is a relatively limited and well-defined area having considered high recreational fishing pressure, but large time series from fish monitoring programmes are lacking. This site will give good opportunities for studying pike, pikeperch and to some extent also sea trout, data collection is suggested to take place every third year. An adjacent area is Kvädöfjärden having fish monitoring time series from 1989. Closely situated to Kvädöfjärden is Licknevarpefjärden where fishing has been prohibited since 1970. Additional areas that are of interest to follow up with some regularity are Asköfjärden, Gålö and / or Lagnö in the Stockholm archipelago. In the future it might be fruitful to shift data collection intensity between Torhamn in Blekinge and an area in Stockholm archipelago. Such decision should be based on factors like where the most practical solutions / contact network can be found. In the Gulf of Bothnia angling with nets, traps and similar gears are relatively widespread. We suggest that Långvind Bay in Gävleborg County, is an area for the study of recreational fishing in a relatively sparsely populated county and is most likely typical for large parts of the Gulf of Bothnia. Data collection is suggested to take place every year. As for the Gulf of Bothnia the recreational fishery in the Bothnian Bay are mainly targeting the whitefish, sea trout and, to some extent also perch. By monitoring the recreational fisheries in Kinnbäcksfjärden near Piteå, we hope to be able to describe the local recreational fishing patterns and then apply these values for catch per effort for most of the coastal strip of the Bothnian Bays. Recreational fishing is widespread in all of the five largest lakes in Sweden, and there is a need for data collection in all five. In Lake Vänern, Lake Vättern and Lake Mälaren there are fish monitoring data of good quality and regularity. However, in the two smallest lakes, Lake Hjälmaren and Lake Storsjön in Jämtland County, few test fishing areas and few studies regarding recreational fishing have been made. For Lake Vättern we suggest that data collection is done every year; especially the archipelago in the northern part of the lake will be an excellent area for the study of recreational fishing for pike. In the other four lakes we propose that data collection is made every third year. By studying recreational fishing - its practitioners, scope, gear-use, and harvest, it will be possible to achieve a more detailed view of how recreational fishing is done and how it varies along the Swedish coast and in the five largest lakes. Such knowledge is important for the managers of common fisheries resources and the monitoring of environmental status and evaluating the recreational goals established by the Swedish governments.
