European seas are encountering an upsurge in competing marine activities and infrastructures. Traditional exploitation such as fisheries, tourism, transportation, and oil production are accompanied by new sustainable economic activities such as offshore windfarms, aquaculture, and tidal and wave energy. One proposed solution to overcome possible competing claims at sea lies in combining these economic activities as part of Multi-Use Platforms at Sea (MUPS). MUPS can be understood as areas at sea, designated for a combination of activities, either completely integrated in a platform or in shared marine space. MUPS can potentially benefit from each other in terms of infrastructure, maintenance, etc. Developing MUPS in the marine environment demands adequate governance. In this article, we investigate four European sites to find out how governance arrangements may facilitate or complicate MUPs. In particular, we apply a framework specifying policy, economic, social, technical, environmental, and legal (PESTEL) factors to explore governance arrangements in four case study sites in different sea basins around Europe (the Mediterranean Sea, the Atlantic Ocean, the North Sea, and the Baltic Sea). The article concludes with policy recommendations on a governance regime for facilitating the development of MUPS in the future.

European oceans are subject to rapid development. New activities such as aquaculture and ocean energy have gained importance. This triggers interest in “multi-use platforms at sea” (MUPS), i.e., areas at sea in which different activities are combined. MUPS are complex features with regards to technology, governance, and financial, socioeconomic, and environmental aspects. To identify realistic and sustainable solutions and designs for MUPS, the MERMAID project applied a participatory design process (PDP) involving a range of stakeholders representing companies, authorities, researchers, and NGOs. This paper evaluates if and how the participatory design process contributed to the design of multi-use platforms. It is based on interviews with the managers of the case study sites and a questionnaire administered to all stakeholders participating in the PDP workshops. Analyzing the four case studies, we conclude that the participatory design process has had a valuable contribution to the development of the four different designs of MUPS, even though the preconditions for carrying out a participatory design process differed between sites. In all four cases, the process has been beneficial in generating new and shared knowledge. It brought new design issues to the table and increased knowledge and understanding among the different stakeholders.

This article presents a vision for an urban food system in Washington DC in 2050 that serves as the centerpiece of a circular economy for the capital region of the United States. Food serves as the connecting link for an inclusive, adaptive, and resilient urban economy embedded in the region. This food economy values natural resources, cultural diversity, and commitment to nature-based innovations. The vision is the result of a three-pronged methodology of: (1) community engagement; (2) a thoughtful, process-focused transformation; and (3) the scaling up of existing urban food initiatives. We argue that small, hyperlocal, neighborhood-based initiatives can become crucial game changers and catalysts of change for entire neighborhoods, cities, and regions. Therefore, we propose a design-based approach to advance our 2050 vision of a circular food system. Our design-based approach consists of three building blocks: (A) systems thinking; (B) the ability to manage wins and tradeoffs; and (C) transitional leadership and cooperation. We explain these building blocks and the way in which they are incorporated in the 2050 vision of Washington DC. We further argue that the food economy is an ideal sector to embark on such a design-based approach due to its systemic nature, its critical position as an indispensable economic sector, and the complex connections it brings to multiple other sectors of the economy. An urban food system can therefore offer the ideal starting point for a transition towards a circular economy.

The United States food system is highly centralized with only three of the fifty states producing more than 75 percent of U.S. fruits and vegetables. The high reliance on long-distance transportation and cold chains undermines the sustainability of the food system and adds to its vulnerability. This was most recently demonstrated during the COVID-19 pandemic which caused significant disruptions to food supply chains. A promising alternative is a more decentralized and localized food system which reduces the reliance on long-distance transportation and long supply chains. Since such a food system will likely consist of smaller producers, questions have been raised about its economic viability. This precipitated the idea of Food Hubs as market aggregators. The model was first introduced by the U.S. Department of Agriculture as a way to aggregate the agricultural product of small farms. It has since evolved to imply a more flexible food system that can complement various parts of the food supply chain. This study develops a framework to assess the social and environmental sustainability contributions of Food Hubs and especially of urban Food Hubs, since 80 percent of U.S. food consumers live in urban and metro areas. Using our framework, we conducted a content analysis of publicly available information for 50 Food Hubs in metropolitan areas across the United States. We find that Food Hubs contribute to environmental sustainability by reducing food transportation through sourcing from local farms. They also perform relatively well in contributing to lowering food waste and loss. Their contributions to improving water management and adopting more sustainable food production methods, however, appear to be less strong. Similarly, Food Hubs appear to enhance some of our selected aspects of social sustainability such as improving access to fresh and healthy food to local consumers, and organizations such as schools and hospitals. Only a few of the Food Hubs in our sample, however, address our other aspects of social sustainability such as improving food security. We conclude our study by offering an aggregate ranking of the sustainability contributions of our selected Food Hubs based on our assessment framework.

This article explores the potentials of art to involve citizens in regional transitions. The Haarzuilens case in the Netherlands is analysed as to how site-specific performances possibly can have added value for regional planning activities. We investigate the artists' use of narratives as an art form to exemplify and make explicit citizens' understanding of their living environment. Our point of departure is the assumption that people make sense of their living environments through narratives. Narratives are understood as subjective representations of a series of events that involve problem definitions, worldviews and aspects of social reality. Our analysis indicates that art is indeed capable of making the narratives of local citizens about their intrinsic place attachments more explicit. This information can be used by planners in their regional activities. Art makes explicit the emotional values, social values and identities connected with the region. It is a challenge to match these narratives with the planners' narrative on regional transitions. We suggest three scenarios for the cooperation of artists and planners in the future.
