The transition from diesel-driven urban freight transport towards more electric urban freight transport turns out to be challenging in practice. A major concern for transport operators is how to find a reliable charging strategy for a larger electric vehicle fleet that provides flexibility based on different daily mission profiles within that fleet, while also minimizing costs. This contribution assesses the trade-off between a large battery pack and opportunity charging with regard to costs and operational constraints. Based on a case study with 39 electric freight vehicles that have been used by a parcel delivery company and a courier company in daily operations for over a year, various scenarios have been analyzed by means of a TCO analysis. Although a large battery allows for more flexibility in planning, opportunity charging can provide a feasible alternative, especially in the case of varying mission profiles. Additional personnel costs during opportunity charging can be avoided as much as possible by a well-integrated charging strategy, which can be realized by a reservation system that minimizes the risk of occupied charging stations and a dense network of charging stations.

Urban farming projects often involve the (temporarily) redevelopment of urban space by local co-productions of citizens and/or entrepreneurs. To realize their ambitions these coalitions often need support of public (government) resources such as time, money, space and regulation (Green Deal Stadslandbouw, 2013). This paper asks the question to what extent the development of urban farming projects can be understood as an example of planning through direct citizen participation/ participatory governance (e.g. Cornwall, 2004; Roberts, 2004) and what this means for the role of the municipal planning professional or civil servant in making these projects successful. Literature on the role of the municipal planner or civil servant in urban farming projects mainly concerns the role as enabler of projects given the many difficulties for projects. However, when looked at the development of urban farming as an example of citizen participation/ participatory governance and the transfer of social functions towards society other roles and tasks of planners seem to be important to make urban farming successful. This discussion paper looks to the role of planners and civil servants in some related government domains such as landscape (e.g. Van Dam et al. 2008, 2010, 2011) and neighbourhood development (e.g. Frieling et al., 2014) to complement our understanding of the role of planners in making urban farming projects successful. With this analysis the paper sets the scene for further research into tools for the planning professional or civil servant to support urban farming. In the paper the situation in Amsterdam serves as an example.
Upcycling has been embraced by circular economy enthusiasts, policy-makers and collaborative initiatives across Europe. Early studies describe upcycling as a concept aimed at resource conservation by keeping products, components and materials at their highest potential value across consecutive product lifecycles, with zero-negative or even potential positive impact on the natural environment. Similarly, more recent literature on the circular economy views upcycling as a strategy to slow and close resource cycles through product life-extension approaches, such as reuse, repair, refurbishment, remanufacturing and repurpose. With growing environmental concerns, upcycling has become a re-emerging theme in literature and practice. Cities offer opportunities for an increasing number of upcycling initiatives, but little is known about what manifestations of upcycling occur specifically in urban areas or how these urban upcycling initiatives emerge. For example, so-called Urban Resource Centers seek to tackle challenges in urban solid waste management by encouraging entrepreneurs to create value from local waste streams. Therefore, our objective is to address this literature gap and explore manifestations of upcycling in a city context by means of qualitative research, following a case-study approach based on data collected from research archives and 17 preliminary interviews with entrepreneurs and experts in urban upcycling of furniture and interior design products. This study contributes to a structured overview of urban upcycling initiatives and the internal and external factors that drive entrepreneurial initiatives and development. Future work will build on this study to make urban upcycling initiatives more widespread and impactful to deliver on their environmental and social goals.

CILOLAB contributes to the transition of the UFT-system towards zero emission city logistics in 2025 by examining, developing and enabling alternatives for urban logistics activities. Specifically, CILOLAB focuses on the transferability and scaling-up of successful logistics initiatives; i.e. concepts that facilitate decoupling between transport towards and in cities. CILOLAB is an action-driven partnership where cities cooperate with transport operators, interest groups, research institutes and societal partners and collaboratively develop new approaches for urban logistical solutions. Through continuous monitoring and impact assessment these solutions are evaluated and further developed within this experimentation environment, all contributing to the CILOLAB ambition.

Lack of physical activity in urban contexts is an increasing health risk in The Netherlands and Brazil. Exercise applications (apps) are seen as potential ways of increasing physical activity. However, physical activity apps in app stores commonly lack a scientific base. Consequently, it remains unknown what specific content messages should contain and how messages can be personalized to the individual. Moreover, it is unknown how their effects depend on the physical urban environment in which people live and on personal characteristics and attitudes. The current project aims to get insight in how mobile personalized technology can motivate urban residents to become physically active. More specifically, we aim to gain insight into the effectiveness of elements within an exercise app (motivational feedback, goal setting, individualized messages, gaming elements (gamification) for making people more physically active, and how the effectiveness depends on characteristics of the individual and the urban setting. This results in a flexible exercise app for inactive citizens based on theories in data mining, machine learning, exercise psychology, behavioral change and gamification. The sensors on the mobile phone, together with sensors (beacons) in public spaces, combined with sociodemographic and land use information will generate a massive amount of data. The project involves analysis in two ways. First, a unique feature of our project is that we apply machine learning/data mining techniques to optimize the app specification for each individual in a dynamic and iterative research design (Sequential Multiple Assignment Randomised Trial (SMART)), by testing the effectiveness of specific messages given personal and urban characteristics. Second, the implementation of the app in Sao Paolo and Amsterdam will provide us with (big) data on use of functionalities, physical activity, motivation etc. allowing us to investigate in detail the effects of personalized technology on lifestyle in different geographical and cultural contexts.
