    Policy mixes and policy feedback: Implications for green industrial growth in the Swedish biofuels industry

    Get PDF
    Policymakers have increasingly voiced an ambition to combine the transition to a climate-neutral society with a “green” domestic industrial agenda. In recent years, innovation systems scholars have advanced the understanding of the evolution of industries around renewable energy technologies as well as the role of policy feedback (and indeed politics) surrounding the development of domestic green industrial development policies. To take a step towards combining these literature streams, the purpose of this paper is to investigate the role of policy mixes and policy feedback in the emergence of domestic green industries. This is achieved in the empirical case of biofuels in Sweden, and the findings show that policy feedback dynamics created difficulties in aligning the national policy mix with the technology and industrial developments in the country. The resulting political uncertainty predominantly hampered the scaling up of domestic production capacity, while R&D and import of biofuels instead could grow strong. Based on this empirical case, a process model is developed to explain the role of policy feedback in the development of domestic industries, thus demonstrating how the growth of domestic industries is driven by the interplay of policy effects and various feedback processes. The findings suggest that future research into the role of policies in “green” domestic industry growth should devote more attention to the dynamics driving the co-evolution of policy, technology and industry structures

    Capacity Factors for Urban Sustainability Transformations – The Eco-capital Suwon in South Korea

    Get PDF
    South Korean cities have experienced remarkable economic growth starting from the 1980s, characterised by energy-dependent models coupled with a rapid, dense urbanisation process. This growth model has incrementally induced carbon-intensive urban structures that have consequently produced socio-environmental degradation and severe challenges to sustainability. A range of efforts to solve such challenges has not succeeded in breaking strong path-dependencies on existing unsustainable structures, and this concern has raised the necessity to develop a new urban approach towards sustainability. Given that concern, a growing body of literature has endeavoured to understand the processes of ‘sustainability transformations’, and shares an underlying assumption that such change co-evolves with societal agency that collectively creates networks, within which decisions and strategies are developed, negotiated, and implemented. This recognition has raised the essential question about which factors are required for the agency to initiate and perform such transformations in the process of urban development. Against this background, this research aims to examine factors that critically influence the emergence of urban transformation processes by exploring interrelations that appear between them. In particular, the research focuses on the critical role of governance characteristics to influence the emergence of transformation factors. In order to explore the factors in practice, a case study is conducted through document analysis and in-depth interviews. The real-world case selected in this research is the Eco-capital Suwon in South Korea, a pioneering model of sustainability-oriented urban development that employs a set of transformative experiments across action domains. Additionally, this case is critical in that its wider context—in which a more state government-led, centralised practice is dominant—would generate abundant dynamics of interactions across administrative scale levels. In order to scrutinise the factors that are employed not only in the Eco-capital in general but more specifically in its different projects, the research selects three projects as the sub-cases based on the different governance characteristics, as well as action domains. The three selected projects cover the domains of (rain) water management, green transportation, and renewable (solar) energy, which display multiple, unique forms of participation of (inter)national/urban/neighbourhood-scale agency from the public and private sector, academia and research institutes, civil society, and Suwon’s individual citizens and residents. The research has derived the primary findings: 1) ‘Inclusive governance’ encompasses collaborative actor networks and partnerships; and 2) Intermediaries working across different domains and scale levels condition the emergence and characteristics of agency-related factors for urban transformations. The research makes a set of contributions not only to theoretical discussions on urban transformation, but also to policy and practice in urban governance and planning. First, the selected case and its analytical design help to display: 1) a less explored phenomenon where cross-scalar interactions are often constrained by wider political systems (‘why cross-scalar interactions could not occur’); and 2) a clearer understanding of the geographical unit that is advantageous for the emergence of multi-system transformations (where multi-system transformations could occur). Second, the empirical findings shed light on discussions surrounding urban transformation by verifying arguments about the significance of governance characteristics. In addition, the case analysis suggests shifting from domain-specific transformations to domain-transecting, co-evolutionary transformations, such as a water-energy nexus approach. By extension, the research provides a set of policy recommendations to accelerate urban transformations. Finally, the research suggests options for future comparative studies on how ‘place’ conditions reconfiguration dynamics in urban development.:Acknowledgements Declaration of authorship Executive summary Table of contents List of tables List of figures Abbreviations Notes on the presentation of findings 1.

    Farmers, seeds and varieties : supporting informal seed supply in Ethiopia

    Get PDF
    Ethiopia is characterized by an enormous diversity in agro-ecosystems, crops and varieties, with the informal seed systems dominant in seed supply for almost all crops. The book addresses strategies and approaches through which professionals can support informal seed supply, and links these with the conservation and use of the huge genetic resource base of crops and local varieties. The book looks at informal seed supply from a number of different angles, introduces key concepts and strategies, and presents case studies from Ethiopia and other countries. It deals with the technical aspects of, quality and availability of, and access to seed, and of supporting informal supply. It also deals with the role of farmers in the conservation and management of local crops and varieties, and the participation of farmers and communities in plant breeding and research. It takes a particular interest in the role of farmer organizations in seed supply, and how this role can be strengthened by developing community and small-scale seed enterprises. The aim of all the strategies, case studies and reflections on experiences presented in this book is to improve the availability of and access to quality seeds and varieties, thereby improving the livelihoods of small-scale farmers in Ethiopia and beyond

    The smart glove or smart data glasses: Digitalization of work means that technology is moving closer to the bodies of employees. It can make movements, vital signs and even emotions visible. Technologies which many people use privately to monitor their sporting activities or health opens up a new dimension of control in the workplace, but also the possibility of supporting employees in complex work processes. Based on case studies of companies in manufacturing and logistics as well as a survey of employees, this study provides insights into operational use cases of wearables and the assessments of employees. It reveals contradictory experiences and a high importance of co-determination and co-design of new technologies by employees and works councils as a condition for using new technologies for improving work quality

    This thesis proposes a new virtual simulation environment designed as element of an interoperable federation of simulator to support the investigation of complex scenarios over the Extended Maritime Framework (EMF). Extended Maritime Framework is six spaces environment (Underwater, Water surface, Ground, Air, Space, and Cyberspace) where parties involved in Joint Naval Operations act. The amount of unmanned vehicles involved in the simulation arise the importance of the Communication modelling, thus the relevance of Cyberspace. The research is applied to complex cases (one applied to deep waters and one to coast and littoral protection) as examples to validate this approach; these cases involve different kind of traditional assets (e.g. satellites, helicopters, ships, submarines, underwater sensor infrastructure, etc.) interact dynamically and collaborate with new autonomous systems (i.e. AUV, Gliders, USV and UAV). The use of virtual simulation is devoted to support validation of new concepts and investigation of collaborative engineering solutions by providing a virtual representation of the current situation; this approach support the creation of dynamic interoperable immersive framework that could support training for Man in the Loop, education and tactical decision introducing the Man on the Loop concepts. The research and development of the Autonomous Underwater Vehicles requires continuous testing so a time effective approach can result a very useful tool. In this context the simulation can be useful to better understand the behaviour of Unmanned Vehicles and to avoid useless experimentations and their costs finding problems before doing them. This research project proposes the creation of a virtual environment with the aim to see and understand a Joint Naval Scenario. The study will be focusing especially on the integration of Autonomous Systems with traditional assets; the proposed simulation deals especially with collaborative operation involving different types of Autonomous Underwater Vehicles (AUV), Unmanned Surface Vehicles (USV) and UAV (Unmanned Aerial Vehicle). The author develops an interoperable virtual simulation devoted to present the overall situation for supervision considering also the sensor capabilities, communications and mission effectiveness that results dependent of the different asset interaction over a complex heterogeneous network. The aim of this research is to develop a flexible virtual simulation solution as crucial element of an HLA federation able to address the complexity of Extended Maritime Framework (EMF). Indeed this new generation of marine interoperable simulation is a strategic advantage for investigating the problems related to the operational use of autonomous systems and to finding new ways to use them respect to different scenarios. The research deal with the creation of two scenarios, one related to military operations and another one on coastal and littoral protection where the virtual simulation propose the overall situation and allows to navigate into the virtual world considering the complex physics affecting movement, perception, interaction and communication. By this approach, it becomes evident the capability to identify, by experimental analysis within the virtual world, the new solutions in terms of engineering and technological configuration of the different systems and vehicles as well as new operational models and tactics to address the specific mission environment. The case of study is a maritime scenario with a representation of heterogeneous network frameworks that involves multiple vehicles both naval and aerial including AUVs, USVs, gliders, helicopter, ships, submarines, satellite, buoys and sensors. For the sake of clarity aerial communications will be represented divided from underwater ones. A connection point for the latter will be set on the keel line of surface vessels representing communication happening via acoustic modem. To represent limits in underwater communications, underwater signals have been considerably slowed down in order to have a more realistic comparison with aerial ones. A maximum communication distance is set, beyond which no communication can take place. To ensure interoperability the HLA Standard (IEEE 1516 evolved) is adopted to federate other simulators so to allow its extensibility for other case studies. Two different scenarios are modelled in 3D visualization: Open Water and Port Protection. The first one aims to simulate interactions between traditional assets in Extended Maritime Framework (EMF) such as satellite, navy ships, submarines, NATO Research Vessels (NRVs), helicopters, with new generation unmanned assets as AUV, Gliders, UAV, USV and the mutual advantage the subjects involved in the scenario can have; in other word, the increase in persistence, interoperability and efficacy. The second scenario models the behaviour of unmanned assets, an AUV and an USV, patrolling a harbour to find possible threats. This aims to develop an algorithm to lead patrolling path toward an optimum, guaranteeing a high probability of success in the safest way reducing human involvement in the scenario. End users of the simulation face a graphical 3D representation of the scenario where assets would be represented. He can moves in the scenario through a Free Camera in Graphic User Interface (GUI) configured to entitle users to move around the scene and observe the 3D sea scenario. In this way, players are able to move freely in the synthetic environment in order to choose the best perspective of the scene. The work is intended to provide a valid tool to evaluate the defencelessness of on-shore and offshore critical infrastructures that could includes the use of new technologies to take care of security best and preserve themselves against disasters both on economical and environmental ones
