Urbanization around the world has taken a flight towards rapid, sometimes uncontrolled growth. Megacities expanded, whilst erasing the developable area and adjusting the existing landscape to artificial water and nature systems. This rampant expansion often leads to monotonous new neighborhoods, often dominated by high rise, or extensive urban sprawl. The financial benefits often dominate the quality of the development. These widespread practices of urban development are hard to modify, to the detriment of sustainability. In this chapter the state of the art of urban development in Sydney and its associated problems are described first. An alternative approach, to take the landscape as the starting point of urbanization is then proposed, before conclusions are drawn.

BackgroundThis research study applied the 'Integrated Energy Landscape Approach and the Ecosystem Services Framework' to formulate a pre-proposal for a Positive Energy District in the Hoogkerk Zuid neighborhood in Groningen, the Netherlands.ResultsThe proposed energy saving and energy generation interventions are sufficient to cover the energy usage of the district, while an energy surplus is generated. The pre-proposal has been developed within a participatory process, organized by the authors in close collaboration with key local stakeholders. The identification of local ecosystem services served as a crucial starting point for this study, while it also served for the basis for analysing the subsequent trade-offs and synergies derived from the proposed energy transition interventions. Then, a sustainable business case model was developed based on this Positive Energy District pre-proposal. The main outcome of the model lies in the value creation through cost savings from not using traditional energy sources and selling electricity to the grid. In addition, the economic value of the preserved ecosystem services and of the synergies generated by the pre-proposal are also included in the model.ConclusionsBeyond the local case, the results lay the groundwork for more systematic studies on merging the methodologies of Positive Energy District development, the Ecosystem Framework and the Integrated Energy Landscape approach. Finally, by adding the benefits of ecosystem services and synergies as a significant contributor in the financial analysis and decision-making process, this study opens the door to a new approach to the evaluation of sustainable projects.

This research study applied the Integrated Energy Landscape Approach and the Ecosystem Services Framework in order to formulate a pre-proposal for a Positive Energy District in the Hoogkerk Zuid neighborhood in Groningen, the Netherlands. The proposed interventions are sufficient to cover the energy usage of the district, while an energy surplus is generated. The pre-proposal has been developed within a participatory process, organized by the authors in close collaboration with key local stakeholders. The identification of the local ecosystem services served as a crucial starting point for this study, while it also provided the transparent information base for analyzing the subsequent trade-offs and synergies derived by the proposed energy transition interventions. Then, a sustainable business case model has been developed based on this Positive Energy District pre-proposal. The main outcome of the model lies within the value creation through cost savings from foregoing traditional energy sources and sale of electricity to the grid, but also through including the economic value of ecosystem services and synergies when integrating the Renewable Energy Technologies. Beyond the local case, the findings lay the groundwork for more systematic studies on merging the methodologies of Positive Energy District development, the Ecosystem Framework and the Integrated Energy Landscape approach. Finally, by adding the benefits of ecosystem services and synergies as a significant contributor in the financial analysis and decision making process, this study opens the door for a new approach of valuing sustainable projects.

In this paper the Feltscaping-method is described, its characteristics and requirements, and some examples of how it was used and further developed. In doing so this paper aims at embedding feltscaping into the existing discourse of arts-based research. Furthermore, it will reflect on possibilities for further development of the Feltscaping method.The development of the method started seven years ago, as Cora Jongsma as a way of delving into the different layers of the landscape connected with the landscape. The product of this process is a feltscape, a representation of the landscape made up of several layers of wool that tells a story about a specific area. The layering in the feltscape, in the beginning, was purely the result of interaction between the creative process, conversations with land users, landscape research and visual experience, drawing a parallel to the formation process of the landscape. Starting as a personal search of the artist on how to connect the feltscapes to the landscape, after a few years, developed into an instrument to stimulate good conversation with people that in one way or another are connected to the landscape. In this way, feltscapes enable the researcher to test and exchange own sensory perceptions and to extent existing knowledge or questions about the landscape by eliciting social interactions.

Urban areas provide a promising context for upcycling due to the concentration of consumers and existence of bulky waste resources. Hence, upcycling initiatives emerge across European cities, but little is known about their manifestations. Building on interviews with twenty-four stakeholders from the urban upcycling ecosystem and three focus groups sessions, a morphological model was created with internal and external business model characteristics to analyse a database of 172 collected Dutch urban upcycling initiatives in the furniture and interior sector. The morphological analysis led to eleven urban upcycling manifestations with distinct business model characteristics that make up five generic categories and a landscape of urban upcycling which facilitate future research into the topic. A research agenda to study quantitative implications, regional differences, collaborative experimentation and scaling strategies of urban upcycling is proposed. Practically, the typology may facilitate policy makers and practitioners to create, scale or accelerate urban upcycling initiatives.

This article discusses the question: where to with sustainable urbanism? It includes a historic review of the concept of sustainable urbanism and reviews of recent literature in the field of eco-cities. Through these reviews, it deliberately interrogates new pathways for sustainable urbanism. The result of this investigation is the insight that there are six design principles that are required to create a sustainable city: a design in which cycles are closed, redundancy is built in, anti-fragility is created, citizens are seen as (design) experts, the landscape is used as the basis, and innovative, rule-breaking designs are developed. These six design principles are then captured in three comprehensive concepts, which together support the design of a sustainable city: the design approach needs to be a (1) society-based; (2) complexity-led, and (3) landscape-driven design approach.

This city profile provides a multi-dimensional overview on the most recent social, economic, political and spatial changes in the city of Amsterdam. We map the social-geography of the city, discussing recent housing and spatial development policies as well as city-regional political dynamics. Today, the city of Amsterdam is more diverse than ever, both ethnically and socially. The social geography of Amsterdam shows a growing core–periphery divide that underlines important economic and cultural asymmetries. The tradition of public subsidies and regulated housing currently allows for state-led gentrification within inner city neighborhoods. Public support for homeownership is changing the balance between social, middle and high-end housing segments. Changes in the tradition of large-scale interventions and strong public planning are likewise occurring. In times of austerity, current projects focus on small-scale and piecemeal interventions particularly oriented to stimulate entrepreneurialism in selected urban areas and often relate to creative economies and sustainable development. Finally, underlying these trends is a new political landscape composed of upcoming liberal and progressive parties, which together challenge the political equilibriums in the city region
