3from the article: Abstract Based on a review of recent literature, this paper addresses the question of how urban planners can steer urban environmental quality, given the fact that it is multidimensional in character, is assessed largely in subjective terms and varies across time. The paper explores three questions that are at the core of planning and designing cities: ‘quality of what?’, ‘quality for whom?’ and ‘quality at what time?’ and illustrates the dilemmas that urban planners face in answering these questions. The three questions provide a novel framework that offers urban planners perspectives for action in finding their way out of the dilemmas identified. Rather than further detailing the exact nature of urban quality, these perspectives call for an approach to urban planning that is integrated, participative and adaptive. ; ; sustainable urban development; trade-offs; quality dimensions

What is this publication about?
In this publication on ‘New urban economies’,
we search for answers and insights to a key
question: how can cities foster economic
development and develop ‘new urban economies’.
And, importantly, how can they do that:
◗ in concertation with different
urban stakeholders, ◗ responding adequately to key challenges
and developments beyond their control, ◗ building on the cities’ own identity,
industries and competences, ◗ in a sustainable way, ◗ and without compromising
weaker groups.

Urban areas provide a promising context for upcycling due to the concentration of consumers and existence of bulky waste resources. Hence, upcycling initiatives emerge across European cities, but little is known about their manifestations. Building on interviews with twenty-four stakeholders from the urban upcycling ecosystem and three focus groups sessions, a morphological model was created with internal and external business model characteristics to analyse a database of 172 collected Dutch urban upcycling initiatives in the furniture and interior sector. The morphological analysis led to eleven urban upcycling manifestations with distinct business model characteristics that make up five generic categories and a landscape of urban upcycling which facilitate future research into the topic. A research agenda to study quantitative implications, regional differences, collaborative experimentation and scaling strategies of urban upcycling is proposed. Practically, the typology may facilitate policy makers and practitioners to create, scale or accelerate urban upcycling initiatives.

RAPPORT
This paper examines the network governance approach of the Dutch Urban Envoy in the context of multilevel governance in the European Union. This paper aims to answer the research question on how the scope of network governance can explore the performance of the Dutch Urban Envoy. By analyzing network characteristics, such as legitimacy, actor-level properties, and network-level properties, this paper seeks to provide a nuanced understanding of the performance of the Dutch Urban Envoy. Drawing on previous research, this paper identifies the applicability and limitations of assessing network characteristics in understanding advocacy processes. The paper successfully visualizes the networks of the Dutch Urban Envoy and explores their roles and mandates, contributing to determining the added value of their position. However, the network governance approach has limitations in explaining the tangible successes and challenges of the Dutch Urban Envoy that cannot be directly attributed to their overall performance.

Logistics services have become crucial in shaping urban spaces and influencing urban dynamics. However, despite growing scholarly and policy attention in recent years, their implications for urban design remain unevenly addressed and insufficiently integrated across themes and methods. Addressing the challenges of urban freight transport does not rely solely on transportation perspectives but instead requires interdisciplinary collaboration. This study conducts a systematic literature review following the PRISMA protocol to examine city logistics through an urban design lens, guided by a framework of six urban design dimensions. The main objectives are to introduce an urban design perspective into the urban freight transport discourse, identify existing research gaps, and propose a framework for future studies. A total of 83 publications were reviewed. A descriptive bibliometric analysis shows that scholarly attention to this topic has significantly increased in the past two years. An inductive thematic analysis reveals four thematic clusters: (1) problematisation, (2) analysis of traffic conflicts, (3) curbside design and management, and (4) freight facility integration. By synthesising these thematic patterns, the study proposes research opportunities within each urban design dimension to guide future investigation. The paper contributes to the literature by offering a comprehensive understanding of freight transport from an urban design perspective, conceptualising urban design as distinct from other urban research fields, and outlining cross-disciplinary pathways that can bridge city logistics and urban design.

Post-war urban neighbourhoods in industrialised countries have been shown to negatively affect the lifestyles of their residents due to their design. This study aims at developing an empirical procedure to select locations to be redesigned and the determinants of health at stake in these locations, with involvement of residents’ perspectives as core issue. We addressed a post-war neighbourhood in the city of Groningen, the Netherlands. We collected data from three perspectives: spatial analyses by urban designers, interviews with experts in local health and social care (n = 11) and online questionnaires filled in by residents (n = 99). These data provided input for the selection of locations to be redesigned by a multidisciplinary team (n = 16). The procedure yielded the following types of locations (and determinants): An area adjacent to a central shopping mall (social interaction, traffic safety, physical activity), a park (experiencing green, physical activity, social safety, social interaction) and a block of low-rise row houses around a public square (social safety, social interaction, traffic safety). We developed an empirical procedure for the selection of locations and determinants to be addressed, with addressing residents’ perspectives. This procedure is potentially applicable to similar neighbourhoods internationally.

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.

Adaptive urban development is the design, construction and continuing evolution of urban areas to anticipate and react to changes in the environment and society. These changes include both processes within the city itself and external developments. It is expected that until 2100 a total of 5 billion people will move to cities. Per day this means a 150,000 people start to live in a city. In the same period resources such as fossil fuels, fresh water resources, phosphates and fertile topsoil are running out. This unprecedented urbanization process will convert a large part of the fertile croplands in urban areas. At the same time the food demand from this shrinking productive area will double due to population increase and rising living standards. Most of the urbanization will take place in vulnerable delta areas. To create a perspective to deal with this huge challenge in the 21st century, two things are needed. First, the current parasite cities need to transform into flood proof ecocities. Transforming the existing cities, however, will not be enough to deal with the challenges the world is facing. The second component of the strategy therefore means that a part of the cities and food production should be located on the water to create more space. Rutger de Graaf is civil engineer, entrepreneur and researcher. At the Rotterdam University of Applied Sciences he works as professor Adaptive Urban Development. He is also director and founding partner of DeltaSync, a leading international floating urbanization specialist, and editor of the Journal of Water and Climate Change at the International Water Association.
