Nature in cities serves a multitude of purposes, one of which is that it provides citizens opportunities to recover from stressful daily urban life. Such stress recovering effects of nature can be experienced through urban green, which in urban planning and design contexts can be divided into large natural areas - urban green space - and small scale elements in urban streets: the urban greenscape. The current study aims at finding the extent to which various small scale natural elements in residential streets and their possible configurations influence citizens' preferences for those streets. The research was conducted through an online survey in four cities in the Netherlands (n = 4,956). It used stated choice methods in a virtual environment street design. The method yielded high quality data, indicating that the use of virtual environments and imagery is suitable for stated choice research in the built environment. The results show that especially trees very strongly influence preference, indicating they deserve more attention and space in cities. Grass, which is typically favored by local governments, and vertical green have the smallest effects in residential streets. Furthermore, the concept of greenscape intensity is introduced as the intensities of both the element and the configuration were found to be highly relevant. The results clearly show that the higher either of these intensities, the more likely a respondent will prefer the greenscape design. Furthermore, low intensity on the one can be compensated by high intensity on the other. With these results, urban design professionals and local governments can better trade-off the different aspects of costs versus positive effects of urban greenscape designs.

This paper examines how a serious game approach could support a participatory planning process by bringing stakeholders together to discuss interventions that assist the development of sustainable urban tourism. A serious policy game was designed and played in six European cities by a total of 73 participants, reflecting a diverse array of tourism stakeholders. By observing in-game experiences, a pre- and post -game survey and short interviews six months after playing the game, the process and impact of the game was investigated. While it proved difficult to evaluate the value of a serious game approach, results demonstrate that enacting real-life policymaking in a serious game setting can enable stakeholders to come together, and become more aware of the issues and complexities involved with urban tourism planning. This suggests a serious game can be used to stimulate the uptake of academic insights in a playful manner. However, it should be remembered that a game is a tool and does not, in itself, lead to inclusive participatory policymaking and more sustainable urban tourism planning. Consequently, care needs to be taken to ensure inclusiveness and prevent marginalization or disempowerment both within game-design and the political formation of a wider participatory planning approach.

Habitat fragmentation caused by urbanization and climate change are important drivers of biodiversity decline and ecosystem degradation (McKinney, 2002). Governmental inaction results in cascade effects, such as the extinction of species and the weakening of ecosystem services that citizens depend on. Alarming studies show the continuing loss of nature within European cities as they densify further to meet the demand for housing (Balikçi et al., 2022). The housing market is currently impacted negatively by economic factors and municipalities often respond by scaling back their sustainability ambitions. To avoid cosmetic greening of cities, the eco-social value of urban developments and their contribution to climate-change adaptation need to be made measurable. Developing nature-based urban areas offers opportunities to increase socio-ecological resilience (McPhearson et al., 2015; Spanjar et al., 2022).In the two-year Nature-Based Area Development study researchers at four Dutch universities collaborated with planning professionals in cities, regions and companies to investigate how nature-based urban development can become a forceful reality. The study applied a combination of methods such as co-research sessions with consortium partners, in-depth interviews with experts and a multiple case study analysis of best practices in the Netherlands and abroad. Malmö and Stockholm are frontrunners in applying innovative green planning instruments such as Green Area Factor to meet high environmental ambitions (Kruuse, 2011). These instruments were also analysed and compared with eco-city projects in the Netherlands to identify their effectiveness in fostering nature and ecosystem services.The analysis shows barriers in governance and spatiality between public and (semi-)private developments. Policy silos and ownership divisions often lead to standalone interventions that negatively impact social and ecological connectedness and projects’ potential for climate-change adaptation. Nature-based urban developments require a proactive effort to understand the precise ecological demands across scales and how they can be harnessed effectively in these complex planning processes. The results of the study provide key lessons and inspiration to enable authorities to implement more effective nature-based planning instruments.

Circular BIOmass CAScade to 100% North Sea Region (NSR) economic activity and growth are mostly found in urban areas. Rural NSR regions experience population decline and negative economic growth. The BIOCAS project expects revitalizing and greening of rural areas go hand in hand. BIOCAS will develop rural areas of the NSR into smart specialized regions for integrated and local valorization of biomass. 13 Commercial running Bio-Cascade-Alliances (BCA’s) will be piloted, evaluated and actively shared in the involved regions. These proven concepts will accelerate adoption of high to low value bio-cascading technologies and businesses in rural regions. The project connects 18 regional initiatives around technologies, processes, businesses for the conversion of biomass streams. The initiatives collaborate in a thematic approach: Through engineering, value chain assessments, BCA’s building, partners tackle challenges that are shared by rural areas. I.e. unsustainable biomass use, a mineral surplus and soil degradation, deprivation of potentially valuable resources, and limited involvement of regional businesses and SMEs in existing bio-economy developments. The 18 partners are strongly embedded in regional settings, connected to many local partners. They will align stakeholders in BCA’s that would not have cooperated without BIOCAS interventions. Triple helix, science, business and governmental input will realize inclusive lasting bio cascade businesses, transforming costly waste to resources and viable business.Interreg IVB North Sea Region Programme: €378,520.00, fEC % 50.00%1/07/17 → 30/06/21
UNStudio, een in Amsterdam gevestigd, internationaal toonaangevend architectenbureau, wil hun Green Mile-plan1 voor het centrum van Amsterdam uitwerken om een 'post-pandemisch groen stedenbouwkundig ontwerp' voor de stad te onderzoeken - kunnen groene gebieden worden (her) ontworpen om ruimte aan voetgangers te geven, terwijl voorkomen wordt dat mensen zich niet op dezelfde plek ophopen? De Corona-pandemie benadrukte ook de noodzaak om vaart te zetten achter duurzaamheidsdoelstellingen, waaronder de ambitie om groenere stedelijke omgevingen te creëren. In dit voorstel wordt stadsmeubilair voor de Green Mile ontworpen en gerealiseerd met hergebruikte materialen, en met post-pandemische stedenbouwkundige en bouwkundige principes. GPGroot en Schijf, leveranciers van rest- en gebruikte bouwmaterialen2, willen hun kennis over circulaire materiaalverwerking en -levering in de stedelijke context graag verder ontwikkelen. Het initiatief van UNStudio biedt een unieke kans om deze kennis te ontwikkelen, in samenwerking met de HvA en het onderzoek in de Robot Studio, dat zich tot nu toe met name richt op circulair gebruik van hout voor binnen-toepassingen. Het project volgt een iteratief ontwerpproces van parametrisch ontwerp en digitale productie. Bij het ontwerp wordt rekening gehouden met functionele eisen en beschikbare materialen, evenals met de specifieke kenmerken van de stedelijke context waar het prototype zou kunnen worden geplaatst. De productie van het prototype zal worden uitgevoerd met 6-assige robots in de HvA Robot Studio. De resultaten zijn ontwerpen en een prototype, maar ook kennis over het verbinden van parametrisch ontwerp en robotproductie met buitentoepassingen, met bijzondere aandacht voor rest- en gebruikte materialen. Innovatieve aspecten zijn de overstap naar structureel belaste buitentoepassingen en het gebruik van een breder scala aan materialen dan alleen hout. Hiermee kan het project bijdragen aan de ontwikkeling van “smart industry” en de circulaire economie, beide relevant voor de maatschappelijke uitdagingen zoals vastgelegd in de nationale Kennis- en Innovatie-Agenda’s voor wetenschap en technologie.
The message we intend to communicate is that in the future, our cities can (partly) feed themselves with healthy foods grown in microbial gardens, which can be part of a household kitchen or community garden for providing fresh green "vegetables" where the energy for the artificial LED lighting for the microbial garden is coming from solar panels on roofs thereby making this system free from fossil energy.For Floriade 2022, we would like to introduce the Urban Microbial garden pop-up restaurant for feeding and greening the city. The menu will include a speciality microbiota vegan burger made from algae, seaweed, fungi and fava beans served on dishes made from baked mycelium. Our objective is to elicit consumer perception and opinion on the future of our new microbial food chain, which is fully sustainable and safer for the environment. Consumer opinions will be video recorded and compiled into a short movie/video for further inspiration and analysis for product/service development. This pop-up restaurant is a logical extension of the Art-Work by 4F.STUDIO (Kim van den Belt, Joshua Kelly, Steven Wobbes) already present in Kavel 123 at Floriade as part of the Light Challenge. The artwork depicts a future object for community gardens which supports the idea of locally produced microbes. Since we already have work at Floriade, this living-lab project has the benefit of broadening the vision of their work through more in-depth and visceral feedback.
