Differences in stakeholders' perceptions, lack of commitment, unused knowledge, and interfering, ineffective, measures are just some of the problems encountered in sustainable urban development projects. Collaborative decisionmaking approaches tackle these problems by creating a shared understanding of the problems faced and of ways to address them. The authors explore how the combined application of two techniques, a decision-support tool and a simulation game, can support decisionmaking for sustainable urban development. The techniques are applied in decisionmaking for real and in fictional sustainable urban renewal projects. Benefits and challenges of this combined approach are discussed based on experiences in seven applications. The main finding is that the use of the decision-support tool combined with the simulation - gaming procedure can support agenda setting and help create a shared understanding of problems and potential solutions in the field of sustainable urban renewal.

In 2017 the municipality of Amsterdam launched a programme to combat a housingshortage and realise ambitious societal goals for 32 of its most deprived neighbourhoods. After decades of urban renewal projects, these areas still scored poorly on most socio-economic indicators. The programme aims to develop more affordable housing for low- and middleincome households, to revitalise the existing public spaces of these neighbourhoods and to improve the residents’ socio-economic position. In addition, the progressive municipal council installed in 2018 intends to democratise urban renewal processes with the aim of increasing community involvement.

As in many large European Cities, Amsterdam is confronted with a large housing boom, partially fuelled by shortcomings in (affordable) housing development. Simultaneously, there is a persistent need to improve neighbourhoods with a weak socioeconomic status. The municipal government aims to both, develop major housing schemes and designate redevelopment areas. In 2017, Amsterdam presented a new urban renewal program for 32 designated deprived neighbourhoods in three boroughs. The program sets out physical housing ambitions, but also intends to anticipate and integrally address social, economic and ecological challenges. To ensure the developments are inclusive, the active involvement of local communities in the decision making process is central part of the new policy. However, a large body of planning literature emphasizes the tendency of large redevelopment processes to become exclusive rather than inclusive. To avoid these pitfalls, new spatial and programmatic governance arrangements may need to be developed. In close collaboration with the municipality and local communities, we conduct empirical action-research on Amsterdam’s urban regeneration program to develop and test promising solutions with practice. The paper analyses the planning process as it evolves. Based on framing theory, we structure and analyse the expected governance barriers hindering the inclusivity during the course of the planning process. The insights gathered regarding inclusivity provide critical input in the conceptualisation of new more forceful inclusive spatial planning strategies. In conclusion, a variety of spatial and programmatic governance arrangements are presented to reinforce the inclusivity of planning processes for a sustained impact of large-scale urban renewal programs.

Worldwide, coral reefs are rapidly declining due to increased sea water temperatures and other environmental stresses (Figure 1). To counter the extinction of major coral reef building species on the island of Bonaire, the non-profit organization Reef Renewal Foundation Bonaire is restoring degraded reef sites using corals that are grown in local nurseries. In these nurseries, corals are propagated on artificial trees using fragmentation. After 6-8 months of growth in the nursery, the corals are transplanted to degraded reef sites around the island. Over the years more than 21.000 corals have been outplanted to reef restoration sites in this way. These corals show high survivorship under natural reef conditions but remain under threat by environmental disturbances, such as increased water temperatures, diseases, and competition with macroalgae. A promising intervention to increase reef persistence and resilience is to manipulate the coral-associated microbiome. At present, the composition of the microbiome in nursery-reared and outplanted corals on Bonaire is unknown. The aim of the current project is to identify and isolate naturally occurring beneficial bacteria that may stimulate the resilience of these corals. Our key objectives are: 1) to assess the presence of functionally beneficial bacteria in corals in nursery and restoration sites on Bonaire using metagenomic screening. 2) to design culture strategies to isolate these functionally beneficial bacteria. In the future, a selection of these beneficial bacteria can be applied to the corals to increase their resilience against environmental disturbances.
Over the last couple of years there is a growing interest in the role of the bicycle in Western urban transport systems as an alternative to car use. Cycling not only has positive environmental impacts, but also positive health effects through increased physical activity. From the observation of the Urban Intelligence team that cycling data and information was limited, we have started the development of cycleprint. Cycleprint stands for Cycle Policy Renewal and INnovation by means of tracking Technology with the objective to enable more customer friendly cycle policy.The initial objective of Cycleprint was to translate GPS data into policy relevant insights to enable customer friendly cycle policy. The online toolkit what Cycleprint has become, answers the questions about:-route choice-speeds-delays at intersections -intensities Because of the success of Cycleprint in the Netherlands the range of features is still under development. As a result of the development of Cycleprint the Dutch organized the fietstelweek. In addition to Cycleprint the Urban Intelligence team developed the cyclescan to explore the effects of cycle network enhancement. The project is developed in direct collaboration with the Provincie Noord-Brabant and Metropoolregio Eindhoven to fulfill the ambition to become cycling region of the Netherlands in 2020.
