Sustainable approaches for waste management and sanitation are key to deal with the environmental and health challenges that growing urbanization is creating around the world. Implementing systems that allow to reuse resources contained in the organic waste streams (OWS) is an approach that can bring many benefits, especially in low-medium income areas as the Latin American and Caribbean region, where excreta, wastewater, and waste are not properly managed. The transformation towards these systems requires not only technological changes, but also changes in the way that urban waste and wastewater are governed. The aim of this study was to assess the capacity of the town of Chía (Colombia) to govern the transition towards resource-oriented sanitation and waste management systems. The Governance Capacity Framework (GCF) was used as a method to evaluate the governance capacity of the town to implement these systems. The assessment revealed that the capacity of Chía to govern the implementation of resource-oriented sanitation and waste management systems was low. Furthermore, governance factors that could be hindering the implementation of these systems were identified. Low level of knowledge of resource recovery from OWS in the public spheres, insufficient collaboration and communication across sectors and institutions that had competences on waste management and sanitation, short-term vision within the local decision-making processes and insufficient incentives to support local entrepreneurship on circular economy. Despite these challenges, analysis also revealed the existence of public-private partnerships and entrepreneurs working in successful initiatives linked with resource-oriented systems in Chía and other towns of Cundinamarca county. The study concluded that in Chía there was a gap between local initiatives of resource recovery from OWS that brought environmental, economic, and social benefits at small scale and its inclusion in the local and regional governance systems. Findings of this study touches upon many governance aspects such as knowledge, legislation, financing and even culture. Further research is needed to look closer to each of those and make concrete, feasible and effective proposals that bring change with a long-term sustainability vision. Finally, when analysing the results of the evaluation and making future proposals, strengths, and shortcomings of applying the GCF as an analytical tool for a specific case study like Chía need to be considered.

Human-elephant conflicts (HEC) in Asian elephant (Elephas maximus) range countries have been increasing during the past half-century and are a major conservation issue for governments. Research suggests studying the spatio-temporal behavioural patterns of E. maximus could indicate behavioural preferences and help mitigate such conflicts. These behavioural preferences could be influenced by factors such as seasonal and lunar cycles, and habitat type. This study aims to determine at what degree these influencing factors are driving E. maximus behaviour and HEC. Considering previous studies on seasonal and lunar cycles and habitat utilisation affecting E. maximus' behaviour and HEC it asks; How do these factors influence E. maximus behaviour and HEC events? Considering these factors, are there any correlations between HEC events and behaviour observed within an adjacent protected forest complex? HEC event data was obtained from the Wang Mee district; a community adjacent to a protected area, the Dong Phayayen – Khao Yai – forest complex in Thailand. This community has undergone increasing HEC in recent years. The data was analysed to identify the effects of the aforementioned factors on HEC frequency. Furthermore, camera trap data within the forest complex are also utilised to analyse the effects of these factors on behaviour, such as changes in the observations of E. maximus' mean distance to forest borders and habitat utilisation measured with relative abundance index (RAI). Analysis of data indicates a significant correlation between lunar and seasonal cycles and HEC events. HEC events were greater during hot and monsoon compared with the cold season. The RAI of E. maximus observations at forest borders were also significantly higher during hot season when compared to RAI at greater distances. First and last quarter moon phases indicated a significant increase in HEC in general. Seasonal and lunar cycles also determined the selection of mixed deciduous forest habitats, indicating a general increase in utilisation during the cold season. Utilisation during the cold season also varied greatly depending on the lunar cycle – increasing during the first quarter and lowest during full moon phases, indicating high variability. The results indicate that studying habitat selection preferences and seasonal and lunar cycles are important factors for park and HEC managers when mitigating conflicts. By understanding E. maximus' behaviour and habitat needs managers can better plan for effective management and HEC mitigation.

The current agricultural policy in the European Union aims at stimulating and facilitating a wide range of agricultural functions besides the production of food and fiber. It goes hand in hand with an increased demand for new services in the agricultural landscape such as nature and history conservation. This new role for the farmer needs to be defined and measured to clarify its significance both to the individual farmer and to the public whose tax money pay for the services. The aim of this thesis is to discuss the new role of agriculture based on material gathered through a special accounting method. All the resources spent on managing agricultural landscapes have been registered continuously on two Swedish farms. On a third farm the same information has been gathered in a farmer's diary and then secondarily transcribed into the same accounting method manual as on the other two farms. Also semi-structured interviews have been performed on these three farms focusing on how and why the farmers manage the agricultural landscape. This thesis shows that the special accounting method is applicable if only a few basic assumptions are made. One such assumption has to do with the division of resources for producing biological and historical value and the resources for producing food and fiber in the agricultural landscape. The evaluation of the method is the main theoretical contribution of this thesis. Another result is that the management practices are relatively time consuming. Moreover the compensation for managing pastures and meadows on the farms within the agri-environmental scheme seems to compensate the extra input of resources in many cases, and factors affecting the degree of compensation are identified in the thesis.

During much of the 20th century, the national party systems of Western Europe remained largely unchanged. However, beginning in the 1970s, these frozen party systems slowly started to melt. As the number of parties has increased, the question of what explains new party entrance has also attracted more scholarly interest. Despite this increased attention, the study of new political parties still suffers from a structuralist bias. The implication is that the fates of new parties are decided almost exclusively by external factors. Some scholars focus on the institutional environment; others emphasize sociological explanations, such as the formation of new cleavages in society. Yet such non-actor-centred perspectives risk being excessively deterministic. They also struggle to explain why some parties succeed in gaining entrance to legislatures while others, seemingly under the same external circumstances, fail. In this thesis, therefore, a new way to study parties and their path to parliament is proposed. Starting with the notion that external conditions alone cannot explain new party entrance, the thesis takes an agency-based perspective. Three sets of strategies are identified as being important means for a party to influence its chances of getting into parliament. They concern the party's resources, its political project and its external relations. In what ways can supply and management of resources, policies and relations with other parties affect the potential for becoming a parliamentary party? Through four in-depth case studies of new entrants into the Swedish national parliament, the Riksdag, the thesis concludes that there are some important commonalities in their paths to parliament. Especially with regard to their resources and their political project, the empirical evidence supports the initial premise: new party entrance is unthinkable without successful strategic behaviour.

This thesis explores the human-environment interaction within the climate-sensitive socio-ecological system of Lake Chilwa in Malawi. It uses the livelihoods framework to analyse various coping strategies to resource scarcity due to lake recessions. The main aim is to understand the processes by which decision-making takes place and the influence of various agents of change on coping with environmental shocks, i.e. water recessions. Lake Chilwa undergoes periodic water recessions with up to twelve incidents recorded between 1900 and 2012. While the lake and its wetland is an economic aquatic agriculture system in between recessions, it is unclear how households around the system survive during the periods of water recessions. Qualitative and quantitative studies were conducted between March 2012 and December 2013 on Chisi Island of Lake Chilwa to evaluate the coping strategies and their major drivers in responding to the periodic lake recessions. Using interpretive analysis, the findings show that people from the Lake Chilwa socio-ecological system have lived in anticipation of periodic environmental shocks due to their deep historical knowledge of the lake level and its fluctuations. This knowledge has been passed from generation to generation. Results further show that the main coping strategies that have stood the test of time for every recession are based on reciprocity and redistribution. These include sharing through kinship ties, hunting wild birds and farming. In many cases coping strategies for each specific recession are driven by political, social and economic factors prevailing at that particular period. Given these conditions, different agents (individuals or communities) make choices designed to maximise their own interests as they scramble to access scarce resources. Although natural resources in these systems are fundamental assets in rural livelihoods, accessing them in times of scarcity requires better governance systems that consider social, political and economic contexts.

In 1991, the Swedish Social Democratic government established the Pensioners' Council at the Ministry of Social Affairs. The Council's purpose and structure were spelled out by the Government in a Commission of Inquiry Directive. According to this, the Council is to be a forum for deliberations between the Government and pensioners' organizations. At the municipal level, Senior Citizens Councils have existed since the 1970s. They fill a similar purpose to that of the Pensioners' Council at the central level, namely to be an arena for political discussions between representatives from pensioners' organizations and the municipality. The purpose of this dissertation is two-fold. First, I describe the influence of pensioners' organizations on the establishment of the pensioners' councils and their political influence – potential as well as actual – in these councils. Second, I seek to explain the influence of pensioners' organizations from a power resources perspective. By doing so, I hope to contribute to our knowledge of the relationship between the welfare state and organized interests. Does this relationship imply the existence of a corporatist or pluralistic power structure? Finally, I also hope to contribute to our understanding of the future development of the welfare state in the light of a global economy and aging population. The empirical investigation on the central level suggests that pensioners' organizations influenced the decision to establish the Pensioners' Council. Moreover, they had actual as well as potential political influence through the council since the early 1990s. There success in influencing government policy is due to the fact that pensioners' organizations represent an important voting group and their employees have expert knowledge. At the local level, the empirical investigation suggests that pensioners' organizations had influence on decisions made by municipalities to establish Senior Citizens Councils. However, opportunities to influence vary at the local level, and pensioners' organizations actual political influence is limited. This limited influence can be explained as a consequence of pensioners' organizations lack of an important power resource at the local level – employed expertise. It is argued in the dissertation that the empirical results do not suggest an existence of a corporatist power structure in social issues. Rather, they point to a pluralistic power structure – i.e. along side producer organizations, other organizations (such as those for welfare consumers) also have an important power position. This, in turn, limits the ability of politicians to cut welfare spending. The case of pensioners' organizations therefore suggests that we cannot expect any drastic downsizing of the Swedish welfare state due to factors such as the globalization of the economy. In light of the aging population, the empirical results suggest that politicians will have to seek other solutions to be able to meet the challenge of financing welfare programs targeting the elderly than making drastic cutbacks in those programs.

This study is about seven women's organizations in Belgrade, Serbia and their relations to domestic and international donors during the period 2003-2006. My main research questions focus on their choices of either domestic or international cooperation partners. How and why did the women organize themselves? What factors were essential when selecting donors? In what ways were the organizations influenced by donors? Through interviews, with organization representatives' concepts such as gift and reciprocity, power and dependency, trust and mistrust and collective identity emerged. These concepts were used as points of departure for developing deeper understanding of women organizations' choice of cooperation partners. The women organizations' basically had two alternatives for cooperation: cooperation with foreign donors which offered funds, organizational development and social networks. Alternately, cooperation with local donors, which offered the equivalent except for the organizational development. Cooperation with the foreign donor has resulted in more professional attitudes to the work that have been desired by other international donors. A result is that they can compete with other women's organizations' for international funding. Cooperation with local donors has led to fewer resources but more independent working practices. For these women organizations' independence was important so they choose partners who, they felt more respected this allowing them to write articles or discuss gender in the media with little external influence. Regardless of the chosen donor the reciprocity is embedded in the relation between the donor and the receiver of aid, which in various ways is beneficial for both parties.

What is the political significance of affiliation with voluntary associations for people with and without foreign backgrounds in Sweden? Does associational affiliation offer an opportunity to influence the political decision-making process for those otherwise disfavoured in terms of political resources? Or does it rather aggravate the political marginalisation of people with foreign backgrounds? This thesis is based on two large-scale surveys that have been designed explicitly to deal with questions of this sort. It is shown that there are substantial differences in associational affiliation between people with and without foreign backgrounds. Interestingly, these differences are strongly correlated with patterns of ethnification and ethnic discrimination in Swedish society. Individuals who have migrated to Sweden from Western Europe and North America participate in voluntary associations to the same extent as native Swedes. In contrast, the levels of associational affiliation are consistently lower among people who have migrated to Sweden from other parts of the world, even controlling for age, education, occupation and other potentially important factors. The study supports the widely held notion that there is a positive causal relation between associational affiliation and political participation. However, this seems to be true only with regard to certain forms of political participation and only seldom to such an extent that differences in associational affiliation can be said to strongly affect the relative levels of political engagement of people with and without foreign backgrounds. In particular, the observed differences in associational affiliation seem to have little to do with the often debated marginalisation of immigrants in the electoral arena. ; Etnisk organisering och politisk integration i storstaden

Agriculture provides the most essential service to mankind, as production of crops in sufficient amounts is necessary for food security and livelihood. This chapter examines the question of whether organic agriculture can produce enough food to meet future demand. This question relates to a moral imperative and any evaluation must therefore be based on objective scientific facts excluding ideological bias, political correctness, economic incentives or environmental opinions. The chapter begins by defining the conditions necessary for a stringent evaluation of crop yields and explains potential pitfalls. Yield data from national statistics, organic and conventional long-term experiments and comparative studies are then compiled and evaluated, followed by a discussion of the main factors behind low-yielding production. In a global perspective, the scientific literature shows that organic yields are between 25 and 50% lower than conventional yields, depending on whether the organic system has access to animal manure. The amount of manure available on organic farms is usually not sufficient to produce similar crop yields as in conventional systems and therefore green manures are commonly used. However, organic crop yields reported for rotations with green manure require correction for years without crop export from the field, which reduces average yield over the crop rotation. When organic yields are similar to those in conventional production, nutrient input through manure is usually higher than nutrient addition in conventional agriculture, but such high inputs are usually only possible through transfer of large amounts of manure from conventional to organic production. The main factors limiting organic yields are lower nutrient availability, poorer weed control and limited possibilities to improve the nutrient status of infertile soils. It is thus very likely that the rules that actually define organic agriculture, i.e. exclusive use of manures and untreated minerals, greatly limit the potential to increase yields. Our analysis of some yield-related statements repeatedly used by advocates of organic agriculture reached the following conclusions: Organic manure is a severely limited resource, unavailable in quantities sufficient for sustaining high crop yields; legumes are not a free and environmentally sound N source that can replace inorganic fertilisers throughout; and low native soil fertility cannot be overcome with local inputs and untreated minerals alone. Agricultural methods severely limiting crop yields are counter-productive. Lower organic yields require compensation through expansion of cropland – the alternative is famine. Combining expected population growth and projected land demand reveals that low-yielding agriculture is an unrealistic option for production of sufficient crops in the future. In addition, accelerated conversion of natural ecosystems into cropland would cause significant loss of natural habitats. Further improvement of conventional agriculture based on innovations, enhanced efficiency and improved agronomic practices seems to be the only way to produce sufficient food supply for a growing world population while minimising the negative environmental impact.

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

Public catering can have a considerable environmental and educational impact. A scenario of more legume and less meat consumption in Sweden was in the present study used as a tool to explore the possibilities of Swedish public school meals to become more sustainable. Strong structuration theory provided a focus on organisational structure and stakeholder influence, enabling a holistic view of the issue at hand. A literature review, on the topics of successful implementation of sustainability projects within public catering and individual agency within school meals, provided a knowledge base from which an online survey and a guide for complementary interviews were built. The survey was aimed at municipal dietary managers and assessed their experiences of working with sustainable school meals and their attitudes towards the dietary scenario. Furthermore, the survey tried out a way of measuring how much legumes and meat are served in school canteens. The complementary interviews focused on individual actors' perceived agency to act for sustainable change. The results suggest that the study participants in general have both the knowledge and interest to make school meals more sustainable. They also saw the more legumes dietary scenario as desirable. Complicating factors are that the priorities of catering organisations and schools are often not well aligned, and resources are lacking to work on collaborations to improve this. It is also often unclear who has the responsibility to make sure teaching on sustainability is carried over from the classroom to the canteen. Individual agents with a high motivation to make positive change can be important drivers of sustainability projects, but for a change such as significantly greener school meals to take place, a whole food culture needs to change. Educational efforts and finding ways of engaging multiple stakeholders in the decisions are needed to this end. Unambiguous political goals, with adequate action plans, would give structure to the work on more sustainable school meals. Finding ways of quantifying and comparing sustainability efforts between municipalities would draw attention to the importance of the matter. The approach that was tried out in the present study however proved to be too impractical to use.

This thesis consists of three empirical case studies, originally published as MERGE- papers ('Papers on transcultural studies' published at MERGE, Centre for Studies on Migration, Ethnic Relations and Globalisation at the Department of Sociology, University of Umeå), brought together and framed by a lengthier introduction. The empirical studies examine Swedish refugee reception activities, including the experiences of refugees themselves, with a focus on organisational and inter-organisational matters, and, in this context, the suitability as well as problems, mechanisms and issues, of implementation. According to Swedish policy aims since the mid-70s, immigrants are guaranteed equality, freedom of choice and partnership in relation to social, political and cultural rights. Based upon this background, an ambitious institutionalisation of refugee reception and integration policy was initiated in 1985, implicating the setting up of a new reception system involving almost every Swedish municipality. However, this political reform came to meet with fundamental problems, such as the absence of clear political goals and a remarkably low priority in the work of local political bodies. As a consequence, the ability and the ambitions of civil servants to apply an integrated approach to the reception process, and to foster growing co-operation among relevant local institutions to improve services and opportunities for integration, have not materialised as intended. These deficiencies of local integration policies appear to be connected with implementation problems, issues and obstacles, such as a lack of developed inter-organisational co-ordination mechanisms, lack of a clear division of labour and responsibility among concerned parties, economic obstruction etc. In addition to this, the resources that local refugee receptions have had at their disposal have been a high degree varying and unstable, with the consequence that the reception's organisation, e.g. as immigrant bureaus, has been subjected to constant remoulding. Continuous initiatives for restructuring the reception procedures seem seldom have been well suited, and in addition to this, there has been a lack of opportunities for influence by the refugees themselves concerning conditions of reception and inroads into integration. The conclusion is, somewhat paradoxical, that many of the refugee reception's political-administrative problems are fabricated by and within the refugee reception system and immigrant policy itself. In the thesis, a general background for necessary improvements of the service for refugees is outlined, making possible a lot of reformistic suggestions. While the thesis lays bare the problems with refugee reception, its policy and implementation, it also acknowledges important positive achievements of Swedish refugee reception and its political-administrative ambitions and framework. The reason that the effects of these positive efforts and achievements haven't materialised in successful integration to a higher degree, is also due to 'external' factors, like exclusion from the labour market, social exclusion through segregation, marginalisation and discrimination, processes of racialisation etc. These kinds of ramifying 'external' factors can only to a limited extent be influenced by local actors alone. The conclusion is that a successful integration cannot be achieved solely through measures within the practical institutional setting of the local refugee reception system itself, but must be underpinned and enforced by a more generalised inclusionary or anti-exclusionary politics, a generally more decided political will and over-all more purposeful measures securing a higher degree of suited implementation. ; digitalisering@umu

The global growth in energy demand continues, but the way of meeting rising energy needs is not sustainable. The use of biomass energy is a widely accepted strategy towards sustainable development that sees the fastest rate with the most of increase in power generation followed by strong rises in the consumption of biofuels for transport. Agriculture, forestry and wood energy sector are the leading sources of biomass for bioenergy. However, to be acceptable, biomass feedstock must be produced sustainably. Bioenergy from sustainably managed systems could provide a renewable and carbon neutral source of energy. Bioenergy systems can be relatively complex, intersectoral and site- and scale-specific. The environmental benefits of biomass-for-energy production systems can vary strongly, depending on site properties, climate, management system and input intensities. Bioenergy supply is closely linked to issues of water and land use. It is important to understand the effects of introducing it as well as it is necessary to promote integrated and synergic policies and approaches in the sectors of forestry, agriculture, energy, industry and environment. Biofuels offer attractive solutions to reducing GHG emissions, addressing energy security concerns and have also other socio-economic advantages. Currently produced biofuels are classified as first-generation. Some first-generation biofuels, such as for example ethanol from corn possibly have a limited role in the future transport fuel mix, other ones such as ethanol from sugarcane or biodiesel made from oils extracted from rerennial crops, as well as non-food and industrial crops requiring minimal input and maintenance and offering several benefits over conventional annual crops for ethanol production are promising. Sugarcane ethanol has greenhouse gas (GHG) emissions avoidance potential; can be produced sustainably; can be cost effective without governments support mechanisms, provide useful and valuable co-products; and, if carefully managed with due regard given to sustainable land use, can support the drive for sustainable development in many developing countries. Sugarcane ethanol - currently the most effective biofuel at displacing GHG emissions - is already mitigating GHGs in Brazil. Jatropha curcas L., a multipurpose, drought resistant, perennial plant has gained lot of importance for the production of biodiesel. However, it is important to point out that nearly all of studies have overstated the impacts of first-generation biofuels on global agricultural and land markets due to the fact that they have ignored the role of biofuel by-products. However, feed by-products of first-generation biofuels, such as dried distillers grains with soluble and oilseed meals are used in the livestock industry as protein and energy sources mitigates the price impacts of biofuel production as well as reduce the demand for cropland and moderate the indirect land use consequences. The production of second generation biofuels is expected to start within a few years. Many of the problems associated with first-generation biofuels can be solved by the production of second generation biofuels manufactured from abundant ligno-cellulosic materials such as cereal straw, sugar cane bagasse, forest residues, wastes and dedicated feedstocks (purpose-grown vegetative grasses, short rotation forests and other energy crops). These feedstocks are not food competitive, do not require additional agricultural land and can be grown on marginal and wasteland. Depending on the feedstock choice and the cultivation technique, second-generation biofuel production has the potential to provide benefits such as consuming waste residues and making use of abandoned land. As much as 97-98% of GHG emissions could be avoided by substituting a fossil fuel with wood fuel. Forest fertilization is an attractive option for increasing energy security and reducing net GHG emission. In addition to carbon dioxide the emissions of methane and nitrous oxides may be important factors in GHG balance of biofuels. Forest management rules, best practices for nitrogen fertilizer use and development of second generation technologies use reduce these emissions. Soils have an important role in the global budget of greenhouse gases. However, the effects of biomass production on soil properties are entirely site and practice-specific and little is known about long-term impact. Soil biological systems are resilient and they do not show any lasting impacts due to intensive site management activities. Land management practices can change dramatically the characteristic and gas exchange of an ecosystem. GHG benefits from biomass feedstock use are in some cases significantly lower if the effects of direct¹ or indirect (ILUC²) land use change are taken into account. LUC and ILUC can impact the GHG emission by affecting carbon balance in soil and thus ecosystem. To understand carbon fluxes in an ecosystem large ecosystem units and time scale are critical. Mitigation measures of the impact of land use change on greenhouse gas emissions include the use of residues as feedstock, cultivation of feedstock on abandoned arable land and use of feedstock by-products as substitutes for primary crops as animal feed. Cropping management is the other key factor in estimating GHG emissions associated with LUC and there is significant opportunity to reduce the potential carbon debt and GHG emissions through improved crop and soil management practices, including crop choice, intensity of inputs, harvesting strategy, and tilling practices. Also a system with whole trees harvesting with nutrient compensation is closely to being greenhouse-gas-neutral. Biochar applied to the soil offers a direct method for sequestrating C and generating bioenergy. However, the most recent studies showing that emissions resulting from ILUC are significant have not been systematically compared and summarized and current practices for estimating the effects of ILUC suffer from large uncertainties. Therefore, it seems to be delicate to include the ILUC effects in the GHG emission balance at a country level. The land availability is an important factor in determining bioenergy sustainability. However, even though food and biofuel/biomass can compete for land, this is not inevitably the case. The pattern of completion competition will e.g. depend on whether food security policies are in place. Moreover, the great potential for uncomplicated biomass production lies in using residues and organic waste, introduction of second generation biofuels which are more efficient in use of land and bioresources as well as restoration of degraded and wasted areas. Agroforestry has high potential for simultaneously satisfying many important objectives at ecosystems, economic and social levels. For example, as a very flexible, but low-input system, alley cropping can supply biomass resources in a sustainable way and at the same time provide ecological benefits in Central Europe. A farming system that integrates woody crops with conventional agricultural crops/pasture can more fully utilize the basic resources of water, carbon dioxide, nutrients, and sunlight, thereby producing greater total biomass yield. Overall, whether food prices will rise in parallel to an increase in biofuel demand will depend, more on trade barriers, subsidies, policies and limitations of marketing infrastructure than on lack of physical capacity. There are plant species that provide not only biofuel resources but also has the potential to sequestrate carbon to soil. For example, reed canary grass (RCG, Phalaris arundinacea L.) indicates the potential as a carbon sink. Harvest residues are increasingly utilized to produce energy. Sweden developed a series of recommendations and good-practice guidelines (GPG) for whole tree harvesting practices. Water has a multifarious relationship to energy. Biofuel production will have a relatively minor impact on the global water use. It is critically important to use low-quality water sources and to select the crops and countries that (under current production circumstances) produce bioenergy feedstock in the water-efficient way. However, local and regional impacts of biofuel production could be substantial. Knowledge of watershed characteristics, local hydrology and natural peak flow patterns coupled with site planning, location choice and species choice, are all factors that will determine whether or not this relationship is sustainable. For example, bioethanol's water requirements can range from 5 to 2138 L per liter of ethanol depending on regional irrigation practices. Moreover, sugarcane in Brazil evaporates 2,200 liters for every liter of ethanol, but this demand is met by abundant rainfall. Biomass production can have both positive and negative effects on species diversity. However, woodfuel production systems as well as agroforestry have the potential to increase biodiversity. A regional energy planning could have an important role to play in order to achieve energy-efficient and cost-efficient energy systems. Closing the loop through the optimization of all resources is essential to minimize conflicts in resource requirements as a result of increased biomass feedstock production. A systems approach where the agricultural, forestry, energy, and environmental sectors are considered as components of a single system, and environmental liabilities are used as recoverable resources for biomass feedstock production has the potential to significantly improve the economic, social, and environmental sustainability of biofuels. The LCA (life cycle analysis) approach takes into account all the input and output flows occurring in biomass production systems. The source of biomass has a big impact on LCA outcomes and there is a broad agreement in the scientific community that LCA is one of the best methodologies for the GHG balance calculation of biomass systems. Overall, maximizing benefits of bioenergy while minimizing negative impacts is most likely to occur in the presence of adequate knowledge and frameworks, such as for example certification systems, policy and guidelines. Criteria for achieving sustainability and best land use practices when producing biomass for energy must be established and adopted. ___________ ¹ Direct land-use change occurs when feedstock for biofuels purposes (e.g. soybean for biodiesel) displace a prior land-use (e.g. forest), thereby generating possible changes in the carbon stock of that land. ² Indirect land-use change (ILUC) occurs when pressure on agriculture due to the displacement of previous activity or use of the biomass induces land-use changes on other lands.

The aim of this thesis is to understand the decision-making processes concerning ice-breaking along the coast of Norrland, with the specific aim to analyse the activities of regional interest groups in the Norrland region and government agents at different administrative levels at the key stages of the decision-making processes: initiation, drafting and decision-making. The thesis also explores how institutional factors at different administrative levels affected the agents that were involved at those stages of the decision-making processes. As navigation along the northern Swedish coast must negotiate winter conditions which causes ports to freeze over, the government ice-breaking service functions as an instrument to compensate the export firms in Norrland for these constrains. Year-round navigation in the north Swedish coastal waters was achieved through a series of decision-making processes that took place during the period from 1940 to 1975. These decision-making processes are important to study since ice-breaking was an integrated component of the expanding heavy basic industries in Norrland and thereby for the rapidly growing exports during the 1950s and 1960s. This period is the decisive point in the economic history of the Norrland region regarding how the natural resources should be exploited and how exports should be advanced. This study concludes that the decision-making processes were initiated by government agents at different administrative levels. Official investigatory commissions were set up at several occasions to deal with issues related to the government ice-breaker service by the ministries responsible for ice-breaker policy. It is also demonstrated that the decision-making processes concerning ice-breaker investments were initiated by the government boards that were responsible for the operation of the ice-breaker service. In this respect, the study concludes that the government activities during the initiation stages should not be confused as a sign of regional interest group passivity on these issues. The activities of the interest groups during the initiation stages were primarily intended to draw attention to the problems caused by winter to regional shipping, in order to put the issue on the political agenda. As the decision-making processes proceeded into the drafting stages, the participation from regional interest groups was much more significant as the government offered interest groups forums and procedures for structural consulting through various organisational arrangements. The regional interest groups that participated in those arrangements were industrial firms in the heavy basic industries sector. In those cases other regional interest groups participated, they would promote the interests of those firms. As a result, the final drafts from committees and government bodies included arguments that favoured an expansion of ice-breaking to promote the growth of the heavy basic industries in the Norrland region. The analysis of the decision-making stages suggests that a combination of institutional factors at different administrative levels contributed to the outcome of the decision-making processes. One result is that the general aims of macro policy such as trade policy, growth policy and regional development policy were favourable towards an expansion of the government ice-breaker service, which would benefit the export industries in the Norrland region. Another result is that the sectoral organization within the government maritime bodies contributed significantly to the outcome of the decision-making processes. Large-scale planning and operational experimentation was allowed to take place within the ice-breaker service, which convinced the government that ice-breaking and winter navigation was a feasible transport alternative.
