Construction and demolition waste (CDW) is the most important waste stream in the EU in terms of mass, with around 340 million tonnes between 2010 and 2018 (EEA, 2020). Most member states achieved a recovery target of 70% for this fraction, however, it is mainly based on backfilling or downcycling. Materials coming from demolition and renovation work are not often available for reuse or recycling activities, with some noticeable exceptions in the case of some pioneering Urban Resource Centres (URCs). URCs are physical centres that promote the circular economy at local level (Partnership on Circular Economy, 2019) prioritizing reuse, preparation for reuse, upcycling and remanufacturing activities over material recycling. This is an emerging concept throughout Europe, that has received much policy attention given its potential to help achieve Circular Economy goals set by the European Commission. So far there have been no systematic analyses of URCs, their operation and their impact. The goal of our paper is twofold: 1) to understand how frontrunning URCs currently operate and 2) to derive conclusions/policy recommendations/design principles for URCs. This article presents a comparison of seven URCs that to some extent allow the reuse of CDW in their locations. The data has been gathered in guided study visits to the different locations, complemented by additional information provided by the managers of the URCs through their yearly reports and follow up conversations. The research took place as part of the project Centers for Urban Resources, Reuse and Remanufacture (Cure+), which aims to establish URC pilots in the four project cities (Riga, Tartu, Kavala and Barcelona).

Construction and Demolition Waste (CDW) is the main driver of resource consumption and waste generation in Europe. Although most European countries achieved 70% recovery rate of CDW, the majority is used for backfilling. Therefore, opportunities for Circular Economy (CE) practices in CDW management are underexploited. This research identifies the innovative practices, barriers, and enablers for developing tailored-made designs of Urban Resource Centre (URC) for managing CDWs in four European cities namely Riga, Tartu, Kavala, and Barcelona. Qualitative methods using multiple case studies were used to draw generalizations from cases. Data was collected from reports and interviews with different stakeholders, and a validation workshop for designing URC of each city. Current innovative practices include recycling and upcycling of CDWs; use of green points, exchange platforms, and waste management apps; repair cafés; selective demolition; and (pilot) initiatives on resource centers that function as material exchange point, recycling center, workstation for repair and creative ideas, and prototyping hub, among others. The identified barriers and enablers can be categorized as governmental, market, and individual factors. First, local governments (municipalities) play a key role for facilitating CDW management via both support such as provision of subsidies, green procurement, and mandatory waste sorting, and through strict regulatory requirements. Second, URCs must be locally rooted with inclusion of citizens, grass roots initiatives, and schools/universities to increase community acceptance, awareness, and education on CDW management. Third, partnerships with local stakeholders, such as repair cafes, waste management companies, and local NGOs, is needed to operate the URCs both in short- and long-terms. And fourth, the creation of niche markets such as linking localism (e.g. locally crafted CE stores) and supplying to businesses in need of CDWs, can support the operation of URCs. The identified barriers and enablers can help further improve the design of URCs for each city.

Uit de samenvatting: "Sinds medio 2017 is het Nationaal Lectorenplatform Urban Energy actief. De betrokken lectoren beogen het praktijkgericht onderzoek rond de gebouwde omgeving op hogescholen te verbinden en te stroomlijnen. Dit doen ze teneinde bij te dragen aan de energietransitie: met duurzame bronnen voorzien in onze energievoorziening. Een belangrijk instrument om de expertise van de lectoren te delen is een digitale onderzoekskaart, die beschikbaar is via: http://www.nlurbanenergy.nl. Daarnaast is er behoefte aan meer inzicht als het gaat om termen als vraagarticulatie en onderzoekssamenwerking. Meer precies wilden we achterhalen wat de behoefte is van het mkb aan praktijkgericht onderzoek van hogescholen in het domein Urban Energy. Daartoe hebben we een verkennende studie uitgevoerd naar praktijkgericht onderzoek binnen het domein Urban Energy. Hiervoor interviewden we de betrokken lectoren en ondernemers uit het innovatief MKB. Daarnaast maakten we gebruik van een enquête die we via verschillende kanalen onder de aandacht brachten bij het innovatief mkb."

The crossroads of living in cities on the one hand and ageing of the population on the other is studied in an interdisciplinary field of research called urban ageing (van Hoof and Kazak 2018, van Hoof et al. 2018). People live longer and in better health than ever before in Europe. Despite all the positive aspects of population ageing, it poses many challenges. The interaction of population ageing and urbanisation raises issues in various domains of urban living (Phillipson and Buffel 2016). According to the Organisation for Economic Co-operation and Development (OECD 2015), the population share of those of 65 years old is expected to climb to 25.1% in 2050 in its member states. Cities in particular have large numbers of older inhabitants and are home to 43.2% of this older population. The need to develop supportive urban communities are major issues for public policy to understand the relationship between population ageing and urban change (Buffel and Phillipson 2016). Plouffe and Kalache (2010) see older citizens as a precious resource, but in order to tap the full potential these people represent for continued human development (Zaidi et al. 2013), the world’s cities must ensure their inclusion and full access to urban spaces, structures, and services. Therefore, cities are called upon to complement the efforts of national governments to address the consequences of the unprecedented demographic shift (OECD 2015). Additionally, at the city level there is a belief to understand the requirements and preferences of local communities (OECD 2015). An important question in relation to urban ageing is what exactly makes a city age-friendly (Alley et al. 2007, Lui et al. 2009, Plouffe and Kalache 2010, Steels 2015, Moulaert and Garon 2016, Age Platform Europe 2018)? Another relevant question is which factors allow some older people in cities to thrive, while others find it hard to cope with the struggles of daily life? This chapter explores and describes which elements and factors make cities age-friendly, for instance, on the neighbourhood level and in relation to technology for older people.

from the article: "Abstract The way in which construction logistics is organised has considerable impact on production flow, transportation efficiency, greenhouse gas emissions and congestion, particularly in urban areas such as city centres. In cities such as London and Amsterdam municipalities have issued new legislation and stricter conditions for vehicles to be able to access cities and city centres in particular. Considerate clients, public as well private, have started developing tender policies to encourage contractors to reduce the environmental impact of construction projects. This paper reports on an ongoing research project applying and assessing developments in the field of construction logistics in the Netherlands. The cases include contractors and third party logistics providers applying consolidation centres and dedicated software solutions to increase transportation efficiency. The case show various results of JIT logistics management applied to urban construction projects leading to higher transportation efficiencies, and reduced environmental impact and increased production efficiency on site. The data collections included to-site en on-site observations, measurement and interviews. The research has shown considerable reductions of vehicles to deliver goods and to transport workers to site. In addition the research has shown increased production flow and less waste such as inventory, waiting and unnecessary motion on site."

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

The debate on tourism in cities, both academically and in practice, has for a long time taken place in relative isolation from urban studies. Tourism is mostly addressed as an external agent and economic force that puts pressure on cities rather than as an interdependent part of city systems. The recent debate on city touristification and excessive dependence on the visitor economy, as well as the associated processes of exclusion, and displacement of local city users, serves to highlight how tourism is an integral part of urban developments. A wider urban perspective is needed to understand the processes underlying the tourism phenomena and more transdisciplinary perspectives are required to analyze the urban (tourism) practices. The current article seeks to contribute to such a perspective through a discussion of the literature on urban and tourism studies, and related fields such as gentrification, mobilities, and touristification. Based on this, theoretical reflections are provided regarding a more integral perspective to tourism and urban development in order to engage with a transversal urban tourism research agenda.

With growing environmental concerns, upcycling has become an important theme in literature and practice. Upcycling can help slow and close resource cycles through product life-extension. Cities offer opportunities for upcycling initiatives and seek to tackle challenges in urban solid waste management by encouraging entrepreneurs to create value from local waste streams in urban resource centres and circular crafts centres. However, little is known about what drives urban upcycling and which barriers and drivers occur. This study explores urban upcycling in the context of the Dutch furniture industry, since The Netherlands positions itself as a ‘circular economy hotspot’ and furniture offers promising opportunities and best practices for upcycling. The analysis of 29 semi-structured interviews with experts engaged in urban upcycling reveals personal motives, drivers and barriers. Personal motives include (1) a personal purpose to ‘do good’, (2) an urge to challenge the status quo and (3) learning and inspiring by doing. Key drivers entail opportunities to (1) engage in collaborative experimentation, (2) participate in cross-sectoral local networks, (3) develop resource-based adaptive competences, (4) respond to increasing demand for upcycled products and (5) make social business activities financially viable. Key barriers perceived by upcycling experts include (1) limitations in resource availability, (2) increasing capacity requirements, (3) negative public quality perception, (4) limited marketing competences and (5) an unequal playing field. This study contributes with a comprehensive definition of urban upcycling and a structured overview of key factors that drive and constrain urban upcycling.

In a matter of weeks last year, discussions regarding tourism in cities changed from how to deal with overtourism to how to deal with ‘no tourism’. Shortly thereafter, a great number of posts on LinkedIn, websites, and blogs highlighted how the tourism crisis that resulted from the COVID-19 pandemic could help reinvent tourism, into something more equal, inclusive, and sustainable. And so, online – at leastin mypersonalonlinebubble – there seemedtobe a real momentum for proper, transformative changes in (urban) tourism. How can we rebuild urban tourism in a sustainable and resilient way?

The adaptation of urbanised areas to climate change is currently one of the key challenges in the domain of urban policy. The diversity of environmental determinants requires the formulation of individual plans dedicated to the most significant local issues. This article serves as a methodic proposition for the stage of retrieving data (with the PESTEL and the Delphi method), systemic diagnosis (evaluation of risk and susceptibility), prognosis (goal trees, goal intensity map) and the formulation of urban adaptation plans. The suggested solution complies with the Polish guidelines for establishing adaptation plans. The proposed methodological approach guarantees the participation of various groups of stakeholders in the process of working on urban adaptation plans, which is in accordance with the current tendencies to strengthen the role of public participation in spatial management. https://doi.org/10.12911/22998993/81658
