Para tanto, utiliza-se como meio de análise o que nos estudos de inovação é nomeado de transição sociotécnica. Dentro dessa análise de transição utilizou-se a abordagem teórica Perspectiva Multinível (PMN) para se proceder com a compreensão da adoção da vitivinicultura, em uma região que tem recebido destaque pela produção de vitis viniferas que dão origem a vinhos finos. Após a apresentação do marco teórico são apontadas duas proposições, ambas relacionadas ao framework PMN, no intuito de somar esforços à teoria já existente em estudos de transição, auxiliando na sistematização de fatores contribuintes à adoção do regime sociotécnico e na compreensão destes na trajetória da produção vitivinícola da Campanha Gaúcha. Para atender os objetivos da pesquisa se procedeu com a coleta de dados em duas etapas, etapas A e B. Ambas realizadas a partir de entrevistas semiestruturadas com categorias pré-definidas. Na etapa A, são identificadas três fases da vitivinicultura na região, a primeira de 1887 a 1969, a segunda de 1970 a 1999 e a terceira de 2000 aos dias atuais. Estas correspondem respectivamente às fases de Experimentação, Estabilização e Resistência identificadas no referencial teórico. Já a finalidade da etapa B é de servir à identificação dos fatores sociotécnicos, suas combinações e como evoluem ao longo do tempo, contribuindo com a adoção da vitivinicultura na Campanha Gaúcha. Na etapa B é possível confirmar as proposições 1 e 2, assim como são destacados os fatores mais favoráveis e menos favoráveis à adoção da vitivinicultura na região. É destacada a análise e sistematização dos fatores multiníveis observados. Entre os fatores da vitivinicultura da Campanha Gaúcha identificados, dá-se destaque aos mais favoráveis à adoção: a característica empreendedora e de motivação, a capacidade de trabalharem em conjunto na identificação de oportunidades e ameaças, assim como o aproveitamento em conjunto de oportunidades e de reconfiguração. Os fatores menos favoráveis à adoção, são: a carga tributária alta sobre o vinho, que desfavorece o vinho fino nacional diante do vinho fino importado; a longa distância da Campanha Gaúcha dos centros maiores, que resulta em mais custos de produção; a ausência de uma cadeia produtiva mais completa para amenizar os custos; e o contrabando de vinhos. / This study aimed to analyze the sociotechnical factors that have contributed to the innovative wine production development in the Campanha Gaúcha region in Southern Rio Grande do Sul State. For such, the sociotechnical transitions methodology was used. Within this transition analysis, the Multi-Level Perspective (MLP) theoretical approach was adopted so as to analyze the wine making industry introduction in a region that has lately grown vitis viniferas, giving rise to fine wines. After a theoretical presentation, two propositions were pointed out, both related to the MLP framework, in order to add to the existing transition studies theory and help in the systematization of factors that can contribute to the adoption of a sociotechnical perspective as well as in understanding the role of these factors in the wine production development in the Campanha Gaúcha region. In order to meet the research objectives, data were collected in two stages, A and B. Both included semi-structured interviews with pre-defined categories. In stage A, three winemaking phases were identified in the region, the first from 1887 to 1969, the second from 1970 to 1999 and the third from 2000 to the present day. These periods correspond respectively to the Experimentation, Stabilization and Resistance phases, which were identified in the theoretical framework. Stage B aimed to identify sociotechnical factors, their combinations and how these evolved over time, thus contributing to the winemaking industry introduction in the Campanha Gaúcha region. Stage B allowed the confirmation of propositions 1 and 2, and highlighted both favorable and unfavorable factors in the winemaking introduction process in the region. The analysis and systematization of the observed multi-level factors are highlighted. Among the most favorable winemaking factors in the Campanha Gaúcha region are: its entrepreneurial and motivational characteristics, the producers' ability to work together to identify opportunities and threats, as well as the joint exploitation of opportunities and reshaping. The least favorable factors were: the high tax burden on wine, which is harmful to national fine wine and favors imported fine wine; the distances between the Campanha Gaúcha and larger centers, which results in higher production costs; the absence of a more comprehensive production chain to mitigate costs; and wine smuggling.

Development and diffusion of building-integrated photovoltaics : analysing innovation dynamics in multi-sectoral technologies

Gazis, Evangelos January 2015 (has links)
The ongoing transformation of the energy system along a more sustainable trajectory requires advancements in a range of technological fields, as well as active involvement of different societal groups. Integration of photovoltaic (PV) systems in the built environment in particular is expected to play a crucial long-term role in the deployment of renewable energy technologies in urban areas, demanding the successful cooperation of planners, architects, engineers, scientists and users. The realisation of that technological change will require innovation at both an individual (within firms and organisations) and a collective (sector) level, giving rise to systemic approaches for its characterisation and analysis of its drivers. This study investigates the processes that either accelerate or hinder the development and diffusion of Building-Integrated PV (BIPV) applications into the market. Affected by developments in both the renewable energy and construction industries, the BIPV innovation system is a multi-sectoral case that has been explored only partially up to now. Acknowledging the fact that drivers of innovation span the globalised BIPV supply chain, this research adopts both an international and a national spatial perspective focusing on the UK. The analysis is based on a novel analytical framework which was developed in order to capture innovation dynamics at different levels, including technological advancements within firms, competition and synergy with other emerging and established innovation systems and pressures from the wider socio-economic configuration. This hybrid functional framework was conceived by combining elements from three academic strands: Technological Innovation Systems, the Multi-Level Perspective and Business Studies. The empirical research is based on various methods, including desktop research, semi-structured interviews and in-depth firm-level case studies. A thorough market assessment provides the techno-economic background for the research. The hybrid framework is used as a guide throughout the empirical investigation and is also implemented in the analytical part of the study to organise and interpret the findings, in order to assess the overall functionality of the innovation system. The analysis has underlined a range of processes that affect the development and diffusion of BIPV applications including inherent technological characteristics, societal factors and wider transitions within the energy and construction sectors. Future approaches for the assessment and governance of BIPV innovation will need to address its hybrid character and disruptiveness with regards to incumbent configurations, in order to appreciate its significance over the short and long term. Methodological and conceptual findings show that the combination of insights from different analytical perspectives offers a broader understanding of the processes affecting innovation dynamics in emerging technologies. Different approaches can be used in tandem to overcome methodological weaknesses, provide different analytical perspectives and assess the performance of complex innovation systems, which may span multiple countries and sectors. By better reflecting complexities, tensions and synergies, the framework developed here offers a promising way forward for the analysis of emerging sustainable technologies.

Setting the seeds for a green growth -A Study of biofuel development in Indonesia’s transport sector

Aaman, Sophia, Hessel Lundberg, Johan Henrik January 2017 (has links)
Climate change poses as one of the major environmental issues on a global scale today, with one of the largest contributor to the climate change being the greenhouse gas (GHG) emissions. GHG emissions in turn is known to a large extent originate in anthropogenic energy use, especially fossil fuel usage. This leads to almost a quarter of the global emissions today being emitted from the transport sector as the sector is primary fueled by fossil fuels. Biofuels have been promoted as a strong candidate for fossil fuel substitution as it has similar properties while being renewable. However, even as biofuels have been increasing annually since 2008 globally, there are still concerns associated with the usages that have hindered its replacement of fossil fuels. Indonesia, one of the most populated countries in Southeast Asia, is projected to be one of the world’s leading economies in 2050. In 2030, Indonesia in projected to have doubled its energy consumption since 2014, indicating that the decisions and actions taken today in Indonesia will have a significant impact on the future fuel consumption. This, in combination with being the largest producer of palm oil in the world, gives it a great potential to be in a leading position in the future production of biofuels, especially biodiesel from palm oil. Additionally, Indonesia has set mandatory targets for biofuel share in the transport sector which indicates that the country also seeks to promote the usages of biofuels. This thesis intends to investigate Indonesia’s potential for biofuel development in the transport sector and which factors that could hinder it. More specifically, this study answers the two questions: (i) Which factors are hampering the development of biofuels in the Indonesian transportation sector from a multi-level perspective? and (ii) What is the projection of the Indonesian transport sector by 2030 in terms of fuel consumption and global warming potential (GWP) and what role could biofuels play in reducing those? The data used were collected by interviews with stakeholders in Indonesia and a literature study, which afterwards was processed with the tools Multi-Level Perspective (MLP) and Long-range Energy Alternatives Planning (LEAP). MLP is a concept aiming to describe how system transitions happens with the help of an examination of the linkages in between technology and society, whereas LEAP is an energy modeling tool used in order to create energy projections in different policy scenario options. In this research, MLP were used to capture and analyze the factors that influence the future implementation of biofuels in Indonesia from a socio-technical perspective, putting forward key barriers for biofuel implementation in Indonesia. LEAP was used to construct a model of the Indonesian transport sector to project the future fuel consumption and GWP emissions. This was used to examine biofuels importance as a fuel through scenarios where different Indonesian policy actions were appraised. Together, these two methods will provide an enlightening and concluding remark on the future possibilities for biofuels in Indonesia's transport sector in this thesis. The major finding of the first research question were that biofuels in Indonesia were being introduced in Indonesia as the government saw economic benefits and a solution to the increased energy demand in Indonesia and an increased energy security in going towards a domestic produced energy source. The need for biofuels were also increased due to an increased global sustainability awareness, which also reached Indonesia. Today, biofuels in Indonesia is in a socio-technical transition pathway to go from a niche innovation to a technology in the regime level, but in order for a breakthrough, a number of barriers needs to be addressed. The most mentioned barriers were the institutional and regulatory barriers, which mainly lays in a lack of cooperation amongst the regulatory institutions and a low rate of success of biofuel laws and regulations. Other barriers were the market barriers, closely connected in a subsidization of fossil fuels in Indonesia and a need for further subsidization of biofuels for the market for biofuels to exist in Indonesia. Furthermore, a technical barrier with the vehicle engine were seen as the engine needs improvements in order for a higher blending of biofuels in the fuel. There was also a concern of the perceived sustainability of biofuels in general (e.g. water scarcity and pollution) which was identified as a hindrance. It was also clear a social change is needed in order to push the biofuel breakthrough and enable it to reach its full potential. Today, the interviewees mainly see a development for the biofuel biodiesel and not for the biofuel bioethanol in Indonesia, which they mainly concluded as there is currently none or very little production and demand for bioethanol in Indonesia, and as well a lack of governmental support for bioethanol development. For the second research question four scenarios were used; Business as Usual (a continuation of current trends), Improved Standards (an investigation of higher emissions standards and an increasing fuel efficiency), Biofuel Mandate (a mandatory biofuel share in fuels) and the Low Carbon scenario (a combination of the previous two as well as introduction of electric vehicles, changed car preferences and higher biofuel blending targets). Cars represents a tenth of the vehicle fleet and the share of diesel car amongst the cars are 5% while gasoline stands for 95%, the rest of the vehicles are gasoline driven motorcycles. The main findings were: the total vehicle fleet will have doubled by 2030. This rapid increase could cause stress on the domestic fuel supply, as the yearly fuel consumption is expected to grow from 770 million GJ in 2014 to 1850 million GJ in 2030, an increase by 140%. In the projection the fossil fuels are blended with biofuels, diesel is mixed with biodiesel while gasoline is blended with bioethanol. The annual diesel fuel consumption is projected to increase from 350 million liters to 1100 million in the Business as Usual scenario where the current trend was expected to continue. The implementation of biodiesel and bioethanol in the Biofuel Mandate scenario. Additionally, the Biofuel Mandate scenario resulted in a 12.6% reduction of GHG emissions during the projected period. The cumulative GHG emissions in the projection is estimated to be 1630 million tonnes of carbon dioxide equivalents in 2030 for the Business as Usual scenario. In the transport sector, gasoline is projected to increase from 23 billion liters to 54 billion liters over the period. In the Improved Standards scenario, where the emission standards are increased from Euro2 to Euro6 in 2030 for cars and Euro4 for motorcycles in 2025 as well as an annual fuel economy improvement of 2%, the total fuel consumption is reduced with 20% and GWP by 18%. It was found that the annual GWP could be reduced by almost 31% below the 2014 level, at 47 million metric tonnes of CO2Eq, if the actions of the Low Carbon scenario were achieved. The barriers associated with the Improved Standards scenario were technical, institutional and regulatory while the Biofuel Mandate scenario also had financial, market and distribution barriers. The Low Carbon scenario had barriers from all of the identified barrier categories. The institutional and regulatory barrier was the most prevailing barrier for all of the scenarios. The recommended actions based on the content of this thesis is to firstly promote collaboration between governmental institutes, stakeholders and authorities and include all stakeholders in the decision progress, this way, frameworks and regulations will have a chance to improve and increase the knowledge about biofuels in all levels. It is also important to implement a stronger biofuel R&D culture, promote a more sustainable biofuel development and increase the public awareness of biofuels. The implementation of biofuels will have a reducing effect on the total GWP and fossil fuel consumption. Gasoline is projected to remain the predominant fuel in the transport sector. Therefore will actions targeting the reduction or substitution of gasoline be more impactful than those towards diesel. However due to the availability and current production capacity of biodiesel there is still potential for higher share of biodiesel in fuels.

Drivers and barriers for a sustainability transition of the current food and agriculture system of the city of Malmö : A case study of the sustainable urban farm and meeting place Botildenborg

Scharfenberg, Coline January 2021 (has links)
Humanity is facing massive sustainability challenges, such as climate change and the associated loss of biodiversity, water scarcity and food insecurity. Capitalist urbanisation drives furthermore profound transformations in rural and urban areas and thus in the agriculture and food systems, presenting both challenges and opportunities. Urban agriculture as a part of a local food system, where food is produced in an urban area and sold to consumers in that area, presents a new food production model, generating innovative tools to lower agricultural land use, improving resource use efficiency and biodiversity. Consequently, great potential can be attributed to a sustainable transformation of the agri-food system through urban agriculture.  Like many cities around the world, Malmö has recognised the need for sustainable development. Therefore, the city of Malmö has been addressing environmental, social and economic challenges for several years and is committed to a holistic and sustainable urban development. Although the city is aware of the benefits of small-scale urban agriculture, there are no policies that enable the upscaling of urban agriculture in the city. Botildenborg, a sustainable urban farm and meeting place in Malmö, on the other hand, has recognised the potential for sustainable business and development through urban agriculture for several years, by setting itself the goal to increase the local and ecologically produced food within the city through this form of agriculture. Botildenborg serves therefore as a case study of this research.  In order to be able to provide indications for policies to shape the transformation steps towards sustainability within the agri-food system in Malmö, structures and patterns, as well as possible drivers and potential obstacles of a sustainable transition, are examined in the course of this research. The empirical results from qualitative and quantitative data are systematically processed using the multi-level perspective in combination with the urban political ecology.  The results indicate that the identified barriers tend to be structural and are predominantly located in the economic and especially the political sphere. It seems that the non-monetary added value from urban agriculture is not perceived to its full potential by the city of Malmö. Botildenborg is stabilising itself mainly through knowledge sharing and network building, and thus will sooner or later be able, through the movement behind the network, to change the dominant agri-food regime. The rapidity of the transformation depends on the political ii willingness of the city of Malmö to explicitly integrate urban agriculture into its policies and regulations.

Dockless electric scooters and the sustainable mobility transition in Stockholm : User study, stakeholder insights and policy perspectives / Elsparkcyklar och omställning till hållbar mobilitet i Stockholm : användaranalys samt insikter från intressenter och policyaktörer

Miller, Marcus January 2020 (has links)
In the context of increasing car ownership in Stockholm, this thesis explores the emergenceof e-scooters in the city and what role they could play in achieving a transition away from carusage.This is explored using theories of sustainable transitions: the multi-level perspective,transition management and strategic niche management. These theories are used to guide theempirical enquiry of this research project and to suggest areas of further research and possiblepolicy recommendations. Empirical Findings This study used a mixed-method strategy consisting of interviews with key stakeholders andan e-scooter user survey (n=408). The interviewees from Stockholm Region and two e-scooter operators were broadly inagreement that e-scooters could have a positive impact going forward, whilst acknowledgingchallenges. The interviews highlighted a good level of both private-private and public-privatecooperation in the industry and signalled that this cooperation is key if e-scooters are to be asustainable aspect of Stockholm’s transportation system. The survey indicated that e-scooters are a poor substitute for private (self-owned) car use i.e.only 4% of recorded journeys shifted away from self-owned car use. However, e-scooterswere found to be a much stronger substitute for taxi/ride-hail journeys with 10% of e-scooterjourneys shifting away from them. Survey findings were used to compare the GlobalWarming Potential (GWP) of e-scooters with the modes people used otherwise. It found thatthe modes people would have used had a GWP of 64g per km travelled, which compared to131g (Moreau et al, 2020) and 125g (Hollingsworth et al, 2019) for e-scooters reported in theliterature and 35g reported in a study conducted on behalf of Voi - an e-scooter company(EY, 2020). For a discussion on these figures please refer to sections 2.2.1 and 6.2.3. The timing of the survey gave a unique opportunity to explore the impact of Covid-19 on escooter journeys. A statistically significant difference between the modal shift of journeystaken before and after the Covid-19 outbreak (P-value= 0.027) was found, with journeystaken during the Covid-19 pandemic more than twice as likely to have shifted away from anytype of car use than journeys taken before the outbreak. The discussion was framed using theories of sustainable transitions. It argued that e-scooterswill not achieve a transition away from mobility on their own. However, if there is a moregeneral switch from ownership to usership in the Stockholm transport sector, e-scooters (andother micro-mobility) could substitute an increased number of taxi/ride-hail journeys whichwould see them contribute to a more environmentally sustainable transportation system. Thefinal part of this thesis discusses policy options that would help e-scooters find a space withinStockholm’s transportation systems where they can best achieve environmental sustainabilitygoals including the importance of using a multi-actor approach, a flexible cap on the numberof e-scooters, environmental merit-based tender processes, e-scooter parking charges andminimum prices. / Denna mastersuppsats handlar om framväxten av elsparkcyklar i i Stockholm, och utforskarvilken roll detta nya färdmedel kan spela för att minska bilanvändning i en situation med ökatbilägande. Detta utforskas med hjälp av teorier om hållbarhetsomställning: "multi-level" perspektiv,transition management och strategisk nisch-management. Dessa teorier används för attvägleda den empiriska undersökningen och föreslå områden för ytterligare forskning ochpolicyrekommendationer. Empiriska resultat Studien har utförts med hjälp av en ”mixed method”-ansats, och grundas bl a i intervjuermed viktiga intressenter och en undersökning med elsparkcykelanvändare (n=408). De intervjuade intressenterna från Stockholmsregionen och två elsparkcykelföretag var i stortsett överens om att elsparkcyklar kan ha en positiv inverkan på hållbart resande, samtidigtsom det finns utmaningar. Intervjuerna belyste en god nivå av både privat-privat ochoffentlig-privat samarbete i branschen och signalerade att detta samarbete är avgörande omelsparkcyklar ska kunna bidra till en hållbar utveckling av Stockholms transportsystem.Undersökningen visade att elsparkcyklar inte ersätter privat (egenägd) bilanvändning i någotstörre avseende: endast 4% av de idenitfierade resorna ersatte privat bilanvändning.Elsparkcyklar visade sig dock vara ett mycket starkare substitut för taxi / "ride-hail" resor:10% av elsparkcykel-resorna ersatte en sådan transport. Undersökningsresultaten användesför att jämföra den globala uppvärmningspotentialen (GWP) för elsparkcyklar med de medelsom användes annars. Det visade sig att de färdmedel som folk skulle ha använt om de intehade åkt elsparkcykel hade en GWP på 64g per km per resa, vilket jämförs med 131g(Moreau et al, 2020) och 125g (Hollingsworth et al, 2019) för elsparkcyklar rapporterade ilitteraturen och 35g rapporterade i en studie utförd på uppdrag av Voi - ettelsparkcykelföretag (EY, 2020). För en djupare inblick i dessa siffror hänvisas till avsnitten2.2.1 och 6.2.3 i uppsatsen. Tidpunkten för undersökningen gav en unik möjlighet att utforska effekterna av Covid-19 påresor med elsparkcyklar. Här visar studien på en statistiskt signifikant skillnad iöverflyttningspotential gällande resor som gjordes före och efter covid-19-utbrottet (P-värde=0,027). De resor som gjordes under covid-19-pandemin hade mer än dubbelt så storsannolikhet att ersätta bilanvändning än resor som gjordes före utbrottet. Diskussionen av studiens resultat tar sin utgångspunkt i teorier om hållbarhetsomställning. Idiskussionen framhålls att endast elsparkcyklar inte kommer bidra till en omställning. Men ihändelse av en mer allmän övergång från ägande till användning inom Stockholmstransportsektor, skulle elsparkcyklar (och annan mikromobilitet) kunna ersätta ett ökat antaltaxi-/"ride-hail" resor, vilket i så fall skulle innebära ett bidrag till ett mer miljömässigthållbart transportsystem. I den sista delen av uppsatsen diskuteras policyalternativ somskulle hjälpa elsparkcyklar att hitta en tydlig nisch inom Stockholms transportsystem, där debäst kan bidra till att realisera övergripande miljö- och hållbarhetsmål. Vidare diskuteras behov av att inkludera flera typer av aktörer, att använda ett flexibelt "tak" på antaletelsparkcyklar, anbudsprocesser som styrs av miljökrav, samt tillämpning avparkeringsavgifter och minimipriser för elsparkcyklar.

Är off-grid framtiden för det svenska elsystemet? : En analys utifrån Flernivå-perspektivet / Is off-grid the future for the Swedish electricity system? : An analysis from the Multi-Level Perspecitve

Hermansson, Caroline, Bergkvist, Karolina January 2019 (has links)
Syftet med detta examensarbete är att studera om scenariot off-grid är en potentiell riktning i framtidens svenska energilandskap, samt undersöka vad som kan driva en sådan utveckling. För detta examensarbete har en kvalitativ forskningsstrategi tillämpats, genom ett abduktivt förhållningssätt till funnen empiri och teori. En empirisk datainsamling har genomförts i form av semistrukturerade intervjuer med ett tiotal aktörer på den svenska elnätsmarknaden. Därefter har en tematisk analys utförts, där det empiriska materialet ställts mot teori. Studien påvisar att det idag finns flertalet faktorer som kan vara drivande för en utveckling mot ett off-grid elsystem. I studiens empiriska material går det att finna tecken på att flertalet informanter tror att en förändring av dagens svenska elsystem behövs. Dock hur troligt det är, att en sådan förändringsprocess sker, finner studien inga belägg eller grunder för. De faktorer som skulle driva utvecklingen mot ett elsystem som karaktäriseras som off-grid kan identifieras som prisutveckling, utveckling i andra sektorer, ändrad tariffsättning, decentralisering, lagstiftning, ökad popularitet samt exempel där off-grid har realiserats. / The purpose of this master thesis is to study whether the off- grid scenario is a potential direction in the Swedish energy landscape of the future, and to investigate what can drive such development. For this master thesis, a qualitative research strategy has been applied, through an abductive approach towards the found empirical material and theory. An empirical data collection has been carried out in the form of semi-structured interviews with ten actors in the Swedish electricity grid market. Subsequently, a thematic analysis has been carried out, in which the empirical material is set against the theory. The study shows that there today are several factors that can drive the development towards an off-grid electricity system in Sweden. In the study’s empirical material, it is possible to find signs that most informants believe that change in today’sSwedish electricity system is needed. However, how likely it is that such a change process will take place, the study finds no evidence for. The factors that would drive the development towards an electricity system characterized by off-grid can be identified as price development, development in other sectors, changed tariff set, decentralization, legislation, increased popularity and examples where off-grid has been realized.

Evaluating Inductive Electric Road Systems Implementation : A multiple case study in Sweden

Nagarasan, Yuvanesh, Francis Xavier, Kevin Raja January 2020 (has links)
Sustainable transportation solutions are the goal for the future. With the technological shit happening in the transportation market towards electric vehicles, the electric road system (ERS) is a necessary technology required to reach the sustainability goals for the future. While many studies show the role of innovation in a socio-technical landscape, many neglect the diffusion process of the innovation which occurs to create a socio-technical change. The nature of this thesis is an exploratory case study with a qualitative approach. To address the study, a literature review for the diffusion of innovation, its characteristics, multi-level perspective, and technology readiness level (TRL) was presented in order to provide a better understanding and build a foundation for the research. A review of scientific articles regarding the electric road system was performed to provide insights and obtain information on the technology. The data from scientific articles were complemented by interviews from experts regarding electric road systems to obtain an understanding of technology if it was to be implemented in the future in Sweden. The empirics collected were analyzed using the literature framework and conclusions were drawn. Analyzing the data was required to find the factors hindering the technology and if there is a window of opportunity for the technology to exist in the Swedish market. Environmental sustainability has been the driving factor, but the rate of diffusion for the technology will depend on the complexity and the maturity of the technology to function as a whole working system. The study contributes to evaluating the implementation of an inductive electric road system in the Swedish context and if it could be a viable solution in the transportation market. The perspectives of the technology in the Swedish market and the motivation for the solution are discussed. An analytical contribution by evaluating if the technology could exist in the future and insights on the diffusion of the technology into the existing landscape.

A Sustainable Intensification of the Swedish Cereals Production / Hållbar intensifiering av den svenska spannmålsodlingen

Joel, Ljungberg, William, Bergqvist January 2015 (has links)
The natural environment will become an increasingly important arena for economic competition in the future. The growing world population and the increased global consumption raise concerns about the sustainability of the current and future use of natural resources. Due to the growing global population the production of agricultural crops and food security is high on the global policy agenda. The purpose of this study has been to investigate the opportunities for a sustainable intensification in the Swedish cereals production and how the Lantmännen cooperative, a company active in the whole cereals value chain can act in order to enable the intensification. The research was conducted as a descriptive case study. Given the comprehensive nature of the purpose of this study, we have studied the Swedish agriculture from a system perspective in order to get the comprehensive understanding of its complexity. The findings presented in this report are based on data from multiple research methods such as interviews with stakeholder in the agriculture, database search, and archive searches. We show in this study that a sustainable intensification of the Swedish cereals production can be realized through utilizing the existing unused farmland registered by the farmer as fallow for a number of consecutive years in a row, which can be described as acreage that is not used for crop production but is still kept in farmable condition. Our study has identified four barriers hindering the intensification; Single payment system, Leasing contract, Logistics and Investment costs. To overcome these barriers we argue that the RO PSS business model is appropriate. By using this model Lantmännen will be able to deliver four different types of values to the farmers. The first value is the intangible value of identity, which let inactive farmers continue to live on their farms while being able to focus on other sources of main income. The second value we name ownerless consumption. This value offers farmers with little capital to start up or expand their production without having to invest in new machinery and equipment. The third value we call safety, which is connected to the barrier of lease contracts identified and the distrust between landowners and tenants. The fourth value, specialization, gives the farmer possibility to leverage overall cereals bulk production by including niche crops. We conclude by arguing that the opportunities for an intensification of the Swedish Cereals production lie in delivering these four values. / Naturen kommer i framtiden bli en alltmer viktig arena för ekonomisk konkurrens. En växande världsbefolkning och en ökad global konsumtion skapar oro kring hållbarheten i vårt användande av naturresurser. På grund av den ökande befolkningsmängden placerar sig frågor såsom produktionen av jordbruksgrödor och livsmedelsförsörjning högt upp på den globala politiska dagordningen. Studiens syfte är att undersöka möjligheter för en hållbar intensifiering av den svenska spannmålsodlingen och hur Lantmännen, ett kooperativt företag som verkar i spannmålets hela värdekedja ska agera för att möjliggöra intensifieringen. Med tanke på den övergripande karaktären av våra frågeställningar har vi studerat det svenska jordbruket ur ett systemperspektiv för att få en övergripande förståelse av dess komplexitet. Forskningen har genomförts i form av en beskrivande fallstudie. Våra resultat baseras på data från flera forskningsmetoder som intervjuer med intressenter inom jordbruket, databassökning, arkivsökning. Vår studie visar att en hållbar intensifiering av den svenska spannmålsodlingen kan realiseras genom att utnyttja befintlig oanvänd jordbruksmark som av jordbrukaren registrerats som träda i flera år i följd. Träda kan beskrivas som jordbruksareal som inte används till växtodling men som fortfarande hålls i odlingsbart skick. För att få denna mark i bruk och därmed möjliggöra en intensifiering krävs det att få bukt med fyra identifierade barriärer inom det svenska jordbrukssystemet; Gårdsstödet, Arrendekontrakt, Logistik och Investeringskostnader. Vi hävdar, baserat på våra resultat och analyser, att affärsmodellkonceptet RO PSS är lämplig att använda då Lantmännen ska lyckas få bukt med barriärerna. Denna modell kommer leverera fyra olika värden till jordbrukarna. Det första värdet har vi döpt till Identitet och är av en immateriell natur som vilket låter inaktiva jordbrukare fortsätta bo kvar på sina gårdar medan de inriktar sig på andra inkomstbaserade verksamheter. Det andra värdet gav vi namnet Ägandefri konsumtion. Detta ger värde till jordbrukaren i form av att jordbrukaren inte behöver låna pengar för höga  investeringskostnader i maskiner och infrastruktur vid uppstart eller expansion av verksamheten. Det tredje värdet kallar vi för Säkerhet, vilket är relaterat till barriären arrendekontrakt där vi har funnet en misstro mellan markägare och arrendatorer. Det fjärde värdet, Specialisering, ger jordbrukaren möjlighet att blanda in specialgrödor i sin produktion, och på så vis skapa en hävstång åt bulkproduktionen. Vår slutsats är att möjligheterna för en intensifiering av den Svenska spannmålsodlingen ligger i att kunna leverera dessa värden.

Opportunities and Challenges for Developing High- tech Urban Agriculture in Sweden: A case study in Stockholm

Shan, Yujing January 2021 (has links)
Food system is complex and encompasses stakeholders from local, regional, and global level. The activities and outcomes of the food system are associated with environmental, economic, and social impacts. Due to the growing population, and urbanization, along with the fact that global food system contributes up to 30% of anthropogenic GHG emission, one of the main contributors to climate change, a sustainable food system that could meet the food demand in the urban areas is in need. Therefore, high-tech urban agriculture (HTUA) that uses advanced technologies and enables food production in a controlled environment is seen as a promising solution, which remains niche in Sweden. This study adopted the sustainable food system approach and used the theory of multi-level perspective (MLP) on sustainability transitions to explore this technology-driven transition and identify the challenges and opportunities in developing HTUA in Sweden. Through the analysis of five Swedish policy documents and interviews with four HTUA initiatives in Stockholm, three main aspects are identified: 1) external context; 2) policy environment; and 3) communication and influence, which are independent but also interconnected. According to the findings, the global environment and Swedish context, such as climatic condition and Swedish consumption, provide HTUA an opportunity to develop. The findings also suggest that though the characteristics of HTUA initiatives and the priorities within the Swedish policy environment have overlapping traits, the policies are not effectively translated into practice and thus making it challengeable to develop HTUA in the long run. Implementing more strict restrictions and regulations on the external price, providing an easier access to urban space, simplifying the procedure for the financial support, raising public awareness towards HTUA, and bridging the knowledge gap among all stakeholders through collaborations and partnerships are suggested to reduce the risk of initiating HTUA. However, further research is still required to understand the potential of HTUA in the transformation towards a sustainable food system.

Omställning till hållbara livsmedelssystem : Kommersiell stadsodling i Stockholm / Sustainability transitions in food systems : Commercial urban farming in Stockholm

Ljungberg, Alice January 2020 (has links)
De storskaliga globala livsmedelssystemen står inför ett antal utmaningar inom hållbar utveckling. Livsmedelssystemens nuvarande utformning resulterar i hållbarhetsproblem som förlust av biologisk mångfald och utarmning av jordar, långa livsmedelskedjor och stora avstånd mellan konsument och producent. Klimatförändringarnas effekter och den ökande urbaniseringen bidrar ytterligare till problematiken. Behovet av en omställning till hållbara livsmedelssystem är därför stort och kräver innovativa lösningar såväl som en omfördelning av naturresurser. Ett exempel på en systeminnovation är stadsodling, som uppvisat potential till högre resurseffektivitet såväl som till ökad social hållbarhet i urbana och stadsnära områden. Trots det ökande intresset för stadsodling tycks det finnas en brist på empiriska studier som undersöker stadsodlingens nuvarande status, sammansättning och olika faktorer för utveckling. Syftet med detta examensarbete är således att identifiera faktorer och förutsättningar som påverkar utvecklingen av stadsodling som en del av omställningen mot en hållbarare livsmedelsproduktion, i den specifika kontexten i Stockholm. Studien tillämpade en flexibel, kvalitativ forskningsdesign och inbegriper en systematisk kartläggning och en kvalitativ fallstudie av kommersiell stadsodling i Stockholm. Det empiriska datamaterialet baseras på en litteraturstudie, semistrukturerade kvalitativa intervjuer och insamling av sekundärdata. En innehållsanalys av det empiriska datamaterialet utfördes med vägledning av ett teoretiskt ramverk baserat på omställningsteori ur ett flernivåperspektiv. Studiens resultat visar att kommersiell stadsodling är ett mångfacetterat såväl som växande fenomen, men att många verksamheter befinner sig i en tidig fas. Den form av kommersiell stadsodling som växt fram mest i Stockholm är klimatkontrollerade inomhusodlingar. Nio av 14 identifierade verksamheter är inomhusodlingar, två är etablerade växthus och tre är utomhusodlingar. Kartläggningen indikerar att kommersiell stadsodling i dagsläget bidrar med omkring 0.5-4% av direktkonsumtionen av örter och sallat i Storstockholm. Det finns dock potential för produktion av större volymer och en större mångfald av grödor i de olika stadsodlingssystemen. Studien identifierade ett flertal faktorer och förutsättningar som påverkar möjligheterna till en utveckling av lokal livsmedelsproduktion genom stadsodling. Byråkratiska, regulatoriska, ekonomiska och kulturella faktorer visade sig utgöra hinder för utvecklingen av stadsodling. Detta indikerar att det krävs politiskt stöd i form av främjande ramverk och policy för markanvändning, som möjliggör och underlättar upplåtelse av mark för kommersiell odling. Andra möjliggörande åtgärder kan vara policyverktyg för att i framtiden kunna underlätta offentlig upphandling av lokal mat. Vidare efterfrågas ett större engagemang och ansvar från näringslivet, i form av ökande investeringar i lokal och hållbar mat samt externa samarbeten mellan aktörer. De indikationer som framkom om att konsumenter i högre utsträckning går runt de dominerande alternativen i livsmedelssystemen och efterfrågar kortare värdekedjor identifierades också som en möjliggörande faktor för den fortsatta utvecklingen av stadsodling. / The globalised food systems are facing extensive challenges concerning sustainable development and are furthermore characterized by long supply chains with numerous food miles, industrial production and large-scale retailers. Dominant agricultural practices result in deforestation, loss of biodiversity and depletion of soil and natural resources. In addition, external factors such as climate change and urbanisation trends increases the complexity of these sustainability issues. Thus, transitions from the dominant food systems to more sustainable alternatives has been suggested in scientific literature. Transitions towards sustainability requires social and technical innovations as well as fundamental changes in the governance of food and agriculture. In light of this, a range of different urban farming practices have increasingly been considered to tackle some of these issues. Despite the growing interest in urban agriculture, there is a lack of extensive empirical studies exploring the current state of various urban farming practices and their role in the existing food systems. This study aims to explore the role of enabling factors that influence the development of commercial urban farming as part of a food sustainability transition, in the Stockholm area. The methodological approach of the project includes a qualitative case study and a mapping of productive urban food systems in Stockholm. The research design is flexible and the empirical data material builds on literature review, semi-structured interviews and secondary data collection. Content analysis is conducted and guided by the conceptual framework consisting of transition theory and the multi-level perspective framework.   The results show that commercial urban farming is a diverse phenomenon gaining momentum in Stockholm. Commercial urban farming in Stockholm mainly consists of controlled environment farming; nine out of 14 establishments are indoor farms, two are well established greenhouses and three are outdoor cultivations. However, commercial urban farming seems to be more characterized by the local aspect and closeness to a dense population, rather than a certain applied technology. The mapping indicates that commercial urban farming in Stockholm is currently meeting 0.5-4 % of the direct consumption of herbs and lettuce in Stockholm, but that the potential production capacity is higher. Furthermore, the study found several enabling factors and barriers that affect the development of local food production through urban farming in Stockholm. Through the lens of the multi-level perspective, the main barriers identified are regulations and politics, economic funding and organizational and cultural structures in the food regime. This indicates that further development of urban farming in Stockholm requires support through frameworks and policy, for example regulations regarding land use, to enable disposal of land and estate for urban agriculture use. Measures to facilitate public procurement of locally produced food could also enable the development of urban farming initiatives. Moreover, interaction and co-operation between various stakeholders is crucial for niche development. Large businesses in the food sector could enable the development of urban farming through investments and partnerships. Finally, consumers could enable the development of urban farming by increasingly choosing the alternative pathways offered by some of the urban farming initiatives.
