Comprehensive understanding of the merits of bottom-up urban development is lacking, thus hampering and complicating associated collaborative processes. Therefore, and given the assumed relevancies, we mapped the social, environmental and economic values generated by bottom-up developments in two Dutch urban areas, using theory-based evaluation principles. These evaluations raised insights into the values, beneficiaries and path dependencies between successive values, confirming the assumed effect of placemaking accelerating further spatial developments. It also revealed broader impacts of bottom-up endeavors, such as influences on local policies and innovations in urban development.

Abstract. In recent years circular economy has become more important for the development of many places including cities. Traditionally, urban development policies have mainly been aiming to improve the socio-economic wellbeing of neighbourhoods. However, technical and ecologic aspects have their effects too and need to go hand in hand. This paper is based on an urban area experiment in the Dutch city of Utrecht. In order to assess urban area developments, typically rather straight-forward quantitative indicators have been used. However, it has proved more complicated to assess multifaceted developments of the area studied in this paper. With the City Model Canvas a multi-layered model is being used to better assess the impact of the urban development being studied. Key findings include that the project studied resulted in more space for companies from the creative industry and the settlement of local ‘circular’ entrepreneurs and start-ups, although it remains unclear to what extent these benefit from each other’s presence. The increase in business activity resulted in more jobs, but it is again unclear whether this led to more social inclusion. From an environmental point of view the project activities resulted in less raw materials being used, although activities and public events bring nuisance to the surrounding neighbourhoods.

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.

In June 2016, two Dutch SME companies which are active in the area of urban solid waste management approached the International Environmental Sciences department of Avans about the current R&D activities on urban solid waste management in cooperation with the Federal University of Minas Gerais (UFMG) Brazil. The companies had interest in developing activities in Brazil, since they are aware of the great potential for exporting both knowledge and technology. Solid waste poses a major problem in Brazil which affects 200 million residents. The Brazilian municipalities collect around 71 million tons solid municipal waste on a yearly basis and only a tiny percentage of this collected waste gets recycled. As such. the overwhelming majority of the collected urban solid waste goes to landfills. Within the State of Minas Gerais there are 850 towns of which 600 have less than 20.000 residents and are agriculturally oriented. Current organic waste composting practices take place under very poor conditions (pathogens and weeds still remain in the compost) and most often the resulting compost product is not well received by its residential and agricultural consumers. As such there is huge room for improvement. The SME companies work with Avans and UFMG to address these challenges. The joint research team consisting of the two Dutch SME companies and the two Research and educational institutes have defined the following research question: What is the current status of organic solid waste management in Minas Gerais and how can cooperation between Brazil and the Netherlands result in a win-win for both countries? Two individual KIEM VANG proposals have been defined in order to address these challenges. The planned activities are a joint effort with professor R. T. de Vasconcelos Barros of the Universidade Federal de Minas Gerais (UFMG) and are executed within the Living Lab Biobased Brazil program (www.biobasedbrazil.org).
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
The Dutch Environmental Vision and Mobility Vision 2050 promote climate-neutral urban growth around public transport stations, envisioning them as vibrant hubs for mobility, community, and economy. However, redevelopment often increases construction, a major CO₂ contributor. Dutch practice-led projects like 'Carbon Based Urbanism', 'MooiNL - Practical guide to urban node development', and 'Paris Proof Stations' explore integrating spatial and environmental requirements through design. Design Professionals seek collaborative methods and tools to better understand how can carbon knowledge and skills be effectively integrated into station area development projects, in architecture and urban design approaches. Redeveloping mobility hubs requires multi-stakeholder negotiations involving city planners, developers, and railway managers. Designers act as facilitators of the process, enabling urban and decarbonization transitions. CARB-HUB explores how co-creation methods can help spatial design processes balance mobility, attractiveness, and carbon neutrality across multiple stakeholders. The key outputs are: 1- Serious Game for Co-Creation, which introduces an assessment method for evaluating the potential of station locations, referred to as the 4P value framework. 2-Design Toolkit for Decarbonization, featuring a set of Key Performance Indicators (KPIs) to guide sustainable development. 3- Research Bid for the DUT–Driving Urban Transitions Program, focusing on the 15-minute City Transition Pathway. 4- Collaborative Network dedicated to promoting a low-carbon design approach. The 4P value framework offers a comprehensive method for assessing the redevelopment potential of station areas, focusing on four key dimensions: People, which considers user experience and accessibility; Position, which examines the station's role within the broader transport network; Place-making, which looks at how well the station integrates into its surrounding urban environment; and Planet, which addresses decarbonization and climate adaptation. CARB-HUB uses real cases of Dutch stations in transition as testbeds. By translating abstract environmental goals into tangible spatial solutions, CARB-HUB enables scenario-based planning, engaging designers, policymakers, infrastructure managers, and environmental advocates.
