The multi-story wood construction industry has been on the rise in the past decades because of new regulations making it legal in Sweden and Finland. Politicians have been suggesting more wood materials in buildings because of the positive environmental impact when wood stores carbon dioxide. Concrete is still the most used material in buildings and many developers have a poor perception of wood. The aim of this project was to analyze the wood construction industry in Sweden and Finland. More specifically to identify enabling and limiting factors and suggest measures for increased usage of wood. The method used was a qualitative and quantitative web survey directed to architects and structural engineers experienced in wood construction. The target group was reached by using connections from the project "Knock on wood" and reaching out to interest organizations. This project found that knowledge gaps among developers and contractors, high costs, and lack of standardized processes were limiting the industry. To overcome these issues and increase the usage of wood, the conclusion was: Industry actors need more education about wood construction, carbon taxes should be implemented on materials, and more prefabricated wood products should be made by the manufacturers. Flervåningsbyggandet med trä har ökat i Sverige och Finland de senaste decennierna efter ändringar i reglerna kring träbyggnad. Politiker föreslår att vi borde använde mer trä inom byggandet för den positiva miljöpåverkan trä ger när det lagrar koldioxid. Cement är fortfarande det materialet som används mest inom flervåningsbyggandet och många byggherrar har en dålig uppfattning av trä. Syftet med den här studien var att analysera träbyggnadsindustrin i Sverige och Finland. Mer specifik, så vill studien identifiera drivkrafter och begränsande faktorer, och sen föreslå åtgärder för att öka användandet av trä. Metoden som användes var en webbenkät för arkitekter och byggnadsingenjörer som har erfarenhet av att jobba med trä. Målgruppen nåddes genom att ...
In this report future annual emissions amounts of gaseous pollutants, particulate matter (PM10) and noise from the non-road mobile machinery sector in Sweden were estimated. The estimates over future emissions amounts were conducted for each year from 2006 to 2020. Special focus has been taken to the impact of European and national legislations, the age distribution of different types and sizes of machinery and measures to reduce the annual emissions. Besides different measures to reduce emissions, corresponding costs were also estimated. The study comprises fuel consumption and emissions of CO2, carbon monoxide (CO), hydrocarbons (HC), nitrogen oxides (NOx), particulate matter (PM), and noise from non-road mobile machinery equipped with diesel engines with a rated engine power of 37 to 560 kW. Non-road mobile machinery for example includes tractors, wheel loaders, excavators, articulate haulers, mobile cranes, combined harvesters, forestry machinery and trucks. The current report was a supplementary study to a report describing a methodology for estimating annual fuel consumption and emissions from the non-road mobile machinery sector in Sweden for year 2006. Inventory data of the year 2006 study was obtained from the Swedish machinery testing institute's machinery inspection operation, statistics of sale returns from trade organisations and the Swedish motor-vehicle register. The number of machinery and annual fuel consumption and emissions amounts for year 2006 is presented in table S1. Besides estimates of annual fuel consumption and emissions amounts, emissions of noise was also derived both at a national level and for a specific construction site. For the case study the results showed that it was possible to reduce the average noise level with more than 3 dB(A) compared with the base scenario just by choosing the machinery fulfilling the strictest noise limits, i.e. Stage II which was mandatory for most machinery from 2006. Other measures simulated included various types of retrofit of noise reduction packages. The specific cost for the different measures to reduce average noise emissions from the specific construction site varied from 4 000 up to more than 500 000 SEK dB-1. For the estimate of future fuel consumption and emissions amounts various simulations were conducted, each with a different measure for reducing the annual amounts. Five main emission reduction measures or programs were studied: - Scrappage program - Alternative fuel program - Voluntary emission regulation program - Retrofit of aftertreatment program - Noise reduction program The impact on engine exhaust gas emissions and noise of the current European emission and noise regulations, Stage I to IV and Stage I to II for emissions and noise respectively were common for all simulations or programs. Besides the impact of European regulations, annual work was set to a fixed value for each type of machinery and year simulated, thus eliminating any potential changes of the state of the market. The result of the baseline scenario "Business as usual" (BAU), i.e. only taking account to the impact of European regulation, is presented in table S2 for four different years Both fuel consumption and emissions of CO2 remains fairly constant as an effect of the assumption that the annual work was set at a fixed value. However, emissions of especially NOx and PM showed a major reduction due to the tighter and tighter regulations. All programs simulated were able to reduce the emissions compared with the BAU scenario with exceptions for emissions of nitrogen oxides, which increased in some of the alternative fuel programs. Both the absolute reduction and cost varied significantly between and within the various programs. Reduction of NOx varied from an accumulated increase in emissions of 25 000 tonne to an accumulated reduction of 22 000 tonne for the studied period from 2006 to 2020. At the same time the accumulated cost for the programs varied from a few hundred million SEK to more than 60 000 million SEK. In table S3, specific reduction cost for each pollutant in SEK kg-1 for eight typical emission reduction programs are presented. The results showed that the most economically favourable alternative for reducing emissions from non-road mobile machinery was the voluntary emissions regulation program, i.e. early introduction of machinery fulfilling coming emission limits. Another important result was that the introduction of alternative fuels as a mean of emissions reduction was associated with rather high costs compared to the actual reduction in emissions. For emissions of nitrogen oxides the specific reduction cost varied from almost 100 SEK kg-1 up to a few hundreds of SEK kg-1 except for the alternative fuel programs, which resulted in a considerable higher cost.
Lawns have a significant influence on the cityscape as one of the essential elements of green spaces and an important part of people's everyday lives. Most people in the Western world view lawns as a compulsory element of the urban landscape, almost an icon, without questioning their social, symbolic, ecological or aesthetic values. This research is a part of the conceptual framework and methodological approaches that are being used in an ongoing transdisciplinary collaboration project to study lawns in Sweden as a social and ecological phenomenon.The overall aim of this study was to investigate social and cultural perceptions of lawns, as well as motives behind decisions about the establishment and management of lawns in Sweden. Two multifamily housing typologies, the 'Million Programme' and People's Homes', were examined due to their dominance in Swedish cities. We also studied how an alternative vision of conventional lawns can be applied and accepted by urban residents. We estimated lawn cover in multi-family housing areas and links to people's perception and use of lawns. Questionnaires, semi-structured interviews and observational studies were used (N = 300). Our results showed that people like lawns even if they do not always directly use them. Lawns cover the most significant amount of outdoor spaces in all multi-family residential areas and accompany people everywhere from the house to the schoolyard or park. The total lawn cover in the study areas was 27.8%. Lawns were particularly valued as important places for different outdoor activities (playing, resting, picnicking, walking, socialising) and enjoying the green colour. However people do not want to use a vast monotonous lawn, but a variety of spaces that provide good conditions for different senses (sound, smell, touch and sight) and activities. Alternative lawns were also appreciated by many citizens, politicians, planners and managers. The implementation of new types of lawns requires special planning and design solutions adjusted for each particular neighbourhood.
This thesis aims to create an understanding of how structures affect grain producers' work with sustainability, and to investigate if perennial grains can be part of the future grain production in Sweden. The agricultural sector is facing a dilemma, both to ensure that ecosystem services are kept intact but also to keep up the global food supply for the growing population. Today's efficient industrial agriculture has contributed to increased emissions and the sector needs a sustainability transition. The food and agriculture industry has a strongly institutionalised structure, which means that fundamental changes take a particularly long time. Swedish grain producers are affected by structures from different levels within the sector which affect their possibility to act sustainable within their business. The current cultivation systems with annual grains requires a lot of tillage which contributes to a lot of emissions. Perennial grains are used in other countries but not yet integrated into the Swedish agricultural sector. The ongoing research development of perennial grains in Sweden is to adapt the crop to the Nordic climate and to develop a perennial grain that can be compared with the current yield and profitability of annual grains. The data collection in this thesis has been conducted through semi-structured interviews with six grain producers in Skaraborg, Västra Götaland. The theoretical framework in the thesis consists of structuration theory and sustainability transitions. The concept duality within structuration theory with structures and actions are applied on the different MLP-levels within sustainability transitions to analyse how the selected grain producers are affected by structures from the different levels and how their individual agency is affected. The results reveal that the institutionalised structures affect the grain producers' attitude towards sustainability within their business through both change inertia and the fear of lowered profitability. Joint structural changes within politics, research and development, consumers, and the grain producers themselves; are needed before the respondent perceives an opportunity to act more sustainably within their day-to-day operations. Most of the respondents consider perennial grains to be more interesting if they had better characteristics such as higher profitability, higher yield, and a higher market demand. The attitude towards perennial grains is positive but the perceived risk of low profitability inhibits implementation. By analysing the grain producers' own context with selected theoretical framework: This study shows that a supporting system is needed that enables increased profitability for sustainable initiatives and sustainability through all levels. Researchers and retailers are important actors in creating resources and structures that make it easy for grain producers to act sustainably. The grain producers themselves need to take risks when they are in situations where they have a choice to act sustainably.
Forest management affects the quantity of CO2 emissions in the atmosphere by carbon sequestration in standing biomass, carbon storage in forest products and production of bioenergy that replace fossil fuels. The main question in this paper is whether forest sequestration is worth increasing at the expense of bioenergy and forest products to achieve EU's emission reduction target to 2050 cost-effectively. The assessment is based on numerical calculations using a dynamic, partial equilibrium model of cost-effective solutions, where three abatement methods in the forest sector are included together with abatement in the fossil fuel sector. The results show that forest sequestration in standing biomass is cost-effective compared to bioenergy. When sequestration is taken into account, net present costs for meeting EU carbon targets can be reduced by 18%. This is achieved through an increase in annual carbon sequestration by 30-158 million ton CO2. The overall cost of reaching the 80 per cent carbon reduction target amounts to 2,002 billion Euros when sequestration is included in the policy, but increases to 2,371 billion Euros without sequestration. Results suggest that forests can serve as a cost-efficient carbon sink over the considered time period.
Environmental assessment (EA) is intended to ensure that environmental issues, in a broad sense, are considered in decision making. EA is globally institutionalised through national and international legislation, policies and guidelines, and a field of practice. However, there is a gap between the expectations on EA presented in these regulatory and guiding documents and how it is addressed in practice. This thesis explores the reasons for this gap, focusing on EA practitioners' daily work. The aims of the research are development of theory and generation of new empirical knowledge about how EA practitioners think and act in their daily practice. At the heart of the research is the development of a conceptual framework, space for action, that centres on practitioners' possibilities for influencing practice. The two-dimensional framework is developed iteratively, through empirical and theoretical investigations. The empirical investigations centre on: challenges for practitioners from the multiple perspectives available to apply when deciding appropriate actions; how practitioners think and act when seeking possibilities to influence practice; and, the consultant's role in determining quality. The theoretical basis for the framework integrates and builds on earlier work by planning theorists and elements from frame theory. The first dimension in the framework concerns how practitioners decide on appropriate actions. This process restricts which perspectives practitioners decide to act on and argue for in practice and, subsequently, which perspectives that have potential to be addressed in EA. The second dimension concerns whether these suggestions for appropriate action are enacted and agreed upon in EA processes. These interactions restrict practitioners' possibilities of exerting influence on practice, in terms of both the actual scope of an EA, and how the issues and impacts included are addressed, hence influencing EA quality. The results reveal that these dimensions are important for understanding the gap between expectations of improvements and actual practice. They also reveal a need to recognise the evolving and multi-perspectival character of EA, together with opportunities for advancing the field of practice through critical reflection, reframing and multi-profession collaboration. Overall, this thesis contributes to understanding the important role of practitioners in shaping the field of practice, and provides a new theorisation that strengthens the practitioner focus in EA research.
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.
This dissertation concerns Sveriges Kommunistiska Parti (SKP) [the Swedish Communist Party] – in 1967 renamed Vänsterpartiet kommunisterna (VPK) [the Left Party – the Communists] and in 1990 renamed Vänsterpartiet (V) [the Left Party] – and the Party's process of coming to terms with history and its communist legacy. The aim of the study is to describe and analyse the SKP/VPK/V's process of coming to terms with history for the period 1956-2006, and to set out and problematise the driving forces and constraining mechanisms of this process. The theoretical framework of the study consists of Gunnar Sjöblom's theory about party strategies of political parties in multi-party systems and Michael Freeden's conceptual approach to ideology analysis. During the period of study the SKP/VPK/V has, like no other political party in Sweden, been ascribed historical guilt regarding its own party history but also regarding the effects of world communism. The Party has thus found itself in a situation where it has had history as an adversary. The process of coming to terms with history has mainly revolved around three issues: independence (1956-1977), international ties (1977-1989) and a broadening beyond the communist tradition (1986-2006). The internal debate within the Party has linked these issues to calls for change aimed at ridding the party of what is considered undesirable elements of the Communist legacy. By analysing the arguments pursued in favour of these calls, it is possible to pick out a number of the driving forces behind the Party's process of coming to terms with history, namely an ambition to obtain vote maximisation, programme realisation and maximisation of parliamentary influence. The urge to distance the Party from certain aspects of its communist past has thus been related to fundamental goals that political parties in multi-party systems seek to obtain. The results of the dissertation show that it is possible to pick out five main constraining mechanisms in the Party's process of coming to terms with history. 1) The safeguarding of Party cohesion. 2) The safeguarding of the distinctive character of the Party. 3) The need to resist external pressure. 4) The desire to avoid unfair apportioning of blame. 5) The safeguarding of the right to define the substance of one's own ideology. The existence of these constraining mechanisms help to explain why the process of coming to terms with history lingered on for several decades, and also why it seems to have been a process of such complexity for the Swedish Communist and Post-Communist Party.
International hydroacoustic surveys have been conducted in the Baltic Sea since 1978. The starting point was the cooperation between the Institute of Marine Research (IMR) in Lysekil, Sweden, and the Institute fur Hochseefisherei und Fishverarbeitung in Rostock, German Democratic Republic, in October ¨ 1978, which produced the first acoustic estimates of total biomass of herring and sprat in the Baltic main basin (Håkansson et al., 1979). Since then there has been at least one annual hydroacoustic survey for herring and sprat and results have been reported to ICES. The Baltic International Acoustic Survey (BIAS), is mandatory for the countries that have exclusive economic zone (EEZ) in the Baltic Sea, and is a part of the Data Collection Framework as stipulated by the European Council and the Commission (Council Regulation (EC) No 199/2008 and the Commission Data Collection Framework (DCF) web page1 ). The IMR in Lysekil is part of the Department of Aquatic Resources within Swedish University of Agricultural Sciences and is responsible for the Swedish part of the EU DCF and surveys in the marine environment. The Institute assesses the status of the marine ecosystems, develops and provides biological advices for the sustainable use of the aquatic resources. The BIAS survey is co-ordinated and managed by the ICES working group WGBIFS. The main objective of BIAS is to assess herring and sprat resources in the Baltic Sea. The survey provides data to the ICES Baltic Fisheries Assessment Working Group (WGBFAS).

Studien redovisar den tredje mätningen som följer upp förändringar av trafikanternas hastighetsval och hastighetsefterlevnad på det kommunala huvudvägnätet i tätort. Resultaten visar att de genomsnittliga reshastigheterna ligger under gällande hastighetsgräns, men att bristande hastighetsefterlevnad fortfarande är ett problem. År 2009 fattades ett riksdagsbeslut som innebar ett mål att antalet dödade i vägtrafiken skulle halveras mellan åren 2007 och 2020. En av indikatorerna för att följa utvecklingen är "hastighetsefterlevnad på det kommunala vägnätet". Ett delmål är att minst 80 procent av trafikarbetet ska ske inom gällande hastighetsgräns. År 2012 var startår för mätserien och under 2015 genomfördes den tredje uppföljande mätningen. ; In 2009 the Swedish Parliament passed a resolution stating that by 2020 the number of fatalities from road traffic crashes should be reduced to half the level in 2007. This corresponds to a maximum of 220 deaths in 2020. In order to monitor progress toward this goal, yearly national follow-up studies are conducted to examine trends in the numbers of people killed and severely injured, along with a number of indicators. One of these indicators is speed limit compliance on the municipality streets; the milestone here is to have at least 80 per cent of all traffic travelling within the speed limit. The aim of the present study is to report the changes between the years 2014 and 2015 concerning driver speed levels and speed limit compliance on the main municipality streets. The annual measurement series started in year 2012 and with the measurement series from 2015, this third follow-up was performed.
The grandiose, but failed, attempts to produce silk in Sweden in the past have been largely ignored by historians. This thesis describes the history of sericulture in Sweden, including three periods of practical trials in 1735-1765, 1830-1898 and 1913-1918. For a long time, the secrets of sericulture were closely guarded in China but by the beginning of the 16th century, knowledge of silk cultivation techniques had reached a number of European countries. The pursuit of domestic silk production was often a costly undertaking instigated by royalty. Since conditions in Sweden and Denmark were partly similar, there was some degree of influence and cooperation between these neighbouring countries. The chapters dealing with attempts at silk production during the 18th century and the history of sericulture in northern Europe are primarily based on printed sources and literature. Several of the 18th century silk farmers documented their experiments, allowing us to follow their efforts and ideas on the feasibility of silk farming in Sweden. The descriptions of the two latter sets of Swedish silk production trials presented in the thesis are primarily based on archive materials, mainly consisting of minutes and annual reports. The history of sericulture in Sweden began in the mid-1730s, when Mårten Triewald conducted experiments and exhaustively described and published these. Carl Linnaeus was a significant influence in Swedish sericulture during this early period. Naturalists were hired as plantation managers and were tasked with supplying the silk industry in Sweden with home-produced raw material. The work was prompted by the desire to find an alternative for the huge Swedish imports of raw silk from China and Southern Europe. However, silk farming never became particularly common, despite the financial incentives available for producing silk and planting mulberry trees during the 1750s in the belief that some 'extravagance' was beneficial for society as a whole. When the 'Hats' position of power ended, so did the financial support for manufacturing luxury goods. Founded in 1830, the Swedish Association for Domestic Sericulture was active for nearly 70 years thanks to foreign influences and the notion that silk farming could be a popular livelihood. Members of the Swedish Royal Family served as patrons and several well-known scientists participated in the projects. The Association furnished mulberry plants and seeds, together with silkworm eggs, most of which were distributed to plantations controlled by the Association or county agricultural societies. However, the Association's annual reports show that many private individuals also planted mulberry trees and some pursued silk farming. Sericulture growing trials were carried out at a number of sites across Sweden, on the initiative of Jacob Berzelius, among others. These trials were mainly funded by Government grants, but numerous wealthy individuals also made contributions to the sericulture venture. Some income was generated by the silk products produced, which were almost solely bought by the Swedish Royal Family. The Swedish Sericulture Association was founded in southern Sweden in 1913 but this third brief foray into sericulture produced few results. All three periods of sericulture trials were initiated by enthusiasts with a firm belief that some silkworm host plants would survive the Nordic climate. There were a number of claims that the white mulberry tree had become acclimatised, but an equal number of cold winters and springs proved the opposite. Ultimately, Swedish sericulture was never economically feasible, since the natural conditions were unfavourable and the output from Swedish silk production was modest, and the cost high, in relation to imported silk. The almost 200-year history of sericulture in Sweden provides an important glimpse into the obsessions and culture of the age, but there were far too many obstacles for the dream of Swedish silk ever to become a reality.
Electoral autocracies have become the world's most common form of non-democratic rule. In hegemonic autocracies in particular, where the president, or his party, always wins by more than 70 percent of the vote, the electoral process comes across as mere window-dressing. Still, both the regime and the opposition take elections seriously. Why? What role do elections play? The article deals with this question while focusing on the Azerbaijani 2013 presidential election, and consists of three parts. The first is a theoretical introduction dedicated to electoral autocracies and authoritarian stability. The next summarizes the election, stressing its purpose for the opposition. The third part analyses whether and how the election contributed to strengthening the authoritarian regime. The study concludes that developments during and after the election year are an illustration of what in previous research is sometimes referred to as the politics of insecurity. Even though the opposition "lost", the relative success of their campaign indicated that change might, after all, be possible. The regime, depending on regular multi-party elections for its democratic alibi, did not appreciate the uncertainty and tried to minimize it by using the "three pillars" on which authoritarian states' stability can be said to rest: legitimacy, repression and cooptation.
Recreational fishing is of high social and economic value worldwide, and participation is increasing at a global scale. The extent and biological effect of recreational fisheries have only recently been characterized on a limited number of targeted stocks in Europe. Several studies have shown that there is an effect of recreational fisheries on stock status in Europe and globally, and the importance of acknowledging this sector is increasingly conceded. In Sweden, recreational fishing is defined by the Swedish Agency for Marine and Water Management as any fishing without a professional licence, i.e. fishing for own consumption, recreation, tourism and for competition. Annual surveys have shown that at least 1.4 million Swedes participate in recreational fisheries at least once per year, and total catches have been estimated to about 18 380 t. The species most frequently caught in Swedish recreational fisheries are perch, pike, brown trout, crayfish, lobster, Zander, salmon, Atlantic mackerel, Atlantic herring, and cod. Recreational fisheries are covered in national as well as international management strategies for sustainable fisheries, in particular the common fisheries policy (CFP). The CFP concerns adopting a precautionary approach to fisheries management, and in support of this the EU Data Collection Framework was introduced in 2001. In accordance with this, member states are obliged to collect data on e.g. recreational fisheries for selected species defined under the DCF (EU, 2008) or EU-MAP (EU, 2016). The current knowledge on recreational fisheries in Sweden is largely based on combined postal surveys and follow-up by telephone conducted by Statistics Sweden (SCB) on behalf of HaV. In this essay, the current knowledge on the Swedish recreational fisheries, available methods and key species is reviewed. Important research topics needing further examination, aiding the fulfilling the data collection obligations and increasing the overall understanding and knowledge of the Swedish recreational fisheries, are stated.
A food system includes many processes and actors that interact at different levels to maintain human` access to food. As the need for the food increases due to population growth, the activities associated with obtaining the food led to pressure on the environment. Climate change, nitrogen and phosphorus flows, ocean acidification, biodiversity loss, and extinction of species are directly related to the agri-food system. Therefore, transforming food production in line with the principles of the SDGs is a major challenge for all of humanity. Aquaponics (AP) is an innovative method of food production that offers sustainability solutions and therefore may be an option for the agri-food transformation. The aim of this thesis was to understand the opportunities and barriers for AP development in Sweden and how AP may penetrate the mainstream market. A qualitative study was conducted with representatives of the Swedish agri-food system where the data was collected through semi-structured interviews and analyzed throw the theoretical lens of the multi-level perspective (MLP) and the concept of protective space. Results showed that there are possibilities as well as blocking mechanisms for the development of AP in Sweden concerning conventional fish and vegetable production. To leave the innovation space and integrate into the market, it is necessary to transform the regime by stretching the legislation and changing the norms and routine for the AP integrated system. Since the AP product fits the norms of the market and the consumers food culture, its further distribution depends on enlightenment and marketing strategies.
