from 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
To realize a more sustainable city logistics system the focus should go beyond reducing emissions only. Next to zero emission vehicles, reduction of urban logistics trips is required in light of several urban, environmental and economic challenges. This contribution focuses on the role of hubs and decoupling points, where logistics flows to and from a city are decoupled from the flows in a city, to optimize the city logistics. For six distinctive hubs or decoupling point concepts, we examine the potential under current market and legal conditions. By decomposing city logistics in subsegments and urban logistics trip structures, we estimate the realistic trip reduction potential of decouple points in the current city logistics conditions.

Ook uit internationaal wetenschappelijk onderzoek blijkt dat er verschillen zijn tussen ouderen in de stad en op het platteland [3-5]. In de rijke delen van de Europese Unie hebben ouderen in de landelijke gebieden een hogere levenstevredenheid dan in de stad. Mensen lijken tevreden in een dorp, wellicht omdat het verwachtingspatroon geringer is. Als het op veroudering aankomt, biedt de hogere dichtheid van de stad een grotere nabijheid tot allerlei diensten die de kwaliteit van leven van ouderen vergroten. Door specifieke economische factoren kunnen deze diensten niet in dezelfde mate worden aangeboden in landelijke gebieden [6]. Woonomstandigheden, zo blijkt uit onderzoek [7], zijn beter voor onze ouderen in de stad dan op het platteland, hoewel de verschillen niet zo uitgesproken groot zijn. En dan heb je nog de gesegregeerde woonwijken voor ouderen, zoals in de Verenigde Staten. Denk daarbij aan Sun City Arizona en The Villages in Florida [8, 9]. Deze wijken bieden een eenheidsworst en zonderen ouderen af in een cocon van geboden comfort, waarbij zij verdwijnen uit het reguliere straatbeeld van omliggende steden. Een in vrijheid gekozen gevangenschap. Een echte seniorvriendelijke stad is een generatievriendelijke stad zoals u wilt, waar niet alleen ruimte is voor één generatie, maar voor alle generaties: van wieg tot graf.
Positive Energy Districts (PEDs) can play an important part in the energy transition by providing a year-round net positive energy balance in urban areas. In creating PEDs, new challenges emerge for decision-makers in government, businesses and for the public. This proposal aims to provide replicable strategies for improving the process of creating PEDs with a particular emphasis on stakeholder engagement, and to create replicable innovative business models for flexible energy production, consumption and storage. The project will involve stakeholders from different backgrounds by collaborating with the province, municipalities, network operators, housing associations, businesses and academia to ensure covering all necessary interests and mobilise support for the PED agenda. Two demo sites are part of the consortium to implement the lessons learnt and to bring new insights from practice to the findings of the project work packages. These are 1), Zwette VI, part of the city of Leeuwarden (NL), where local electricity congestion causes delays in building homes and small industries. And 2) Aalborg East (DK), a mixed-use neighbourhood with well-established partnerships between local stakeholders, seeking to implement green energy solutions with ambitions of moving towards net-zero emissions.
A number of universities of applied sciences do a lot of research in the field of sustainable last mile logistics. Collaboration and coordination take place through joint projects or through seminars. However, this collaboration could be more structured so that researchers can always take full advantage of each other's knowledge and are not dependent on having or not having joint projects or seminars. This also concerns the question of how these studies can gain extra added value through joint programming (this can partly be done in the development of a tool/benchmark, see previous point), but also in having and getting research and knowledge from the different regions. Within the new research agenda of the Logistics Knowledge Agreement (the lectors platform of the CoE KennisDC Logistics), urban logistics has been named as one of the four core themes on which the involved universities of applied sciences want to collaborate across regions. In addition, there is only limited cooperation in the field of education around the theme of “urban logistics”. Students who want to graduate in urban logistics or do internships must therefore first learn a lot.
