Contemplating ‘Quality Street’

Een holistisch perspectief op binnenstedelijke herontwikkeling Spatial Planning http://www.uu.nl/agenda/promotie-een-holistisch-perspectief-op-binnenstedelijke-herontwikkeling Promovendus Rien van Stigt onderzoekt waarom het moeilijk is om milieukwaliteit een prominente plaats te geven in de besluitvorming over ruimtelijke plannen. In zijn proefschrift ontwikkelt hij een holistisch perspectief op het complexe proces van compacte binnenstedelijke herontwikkeling. De kwaliteit van de stedelijke leefomgeving is essentieel in duurzame stedelijke ontwikkeling. Die kwaliteit staat met name bij compacte binnenstedelijke herontwikkeling onder druk, en daarom is milieukwaliteit een belangrijke factor in het plannen van zulke ontwikkelingen. Uit de literatuur over de integratie van milieubeleid blijkt dat dit, vooral op lagere bestuurlijke niveaus, niet altijd goed lukt. Er is nog geen overtuigende verklaring waarom dit zo is.

Transformation towards green cities

Cities worldwide are growing at unprecedented rates, compromising their surrounding landscapes, and consuming many scarce resources. As a consequence, this will increase the compactness of cities and will also decrease the availability of urban green space. In recent years, many Dutch municipalities have cut back on municipal green space and itsmaintenance. To offer a liveable environment in 30 to 50 years, cities must face challenges head-on and strive to create green urban areas that build on liveable and coherent sustainable circular subsystems.

Stormwater quality and sustainable urban drainage management

A baseline study was performed to characterize the stormwater quality from the upstream roofs and road areas. Results showed variations in stormwater quality. This may inhibit single-step treatment performance. Therefore, a ‘treatment train’ of several SUDS measures was developed in order to achieve high pollutionremoval rates and to help prevent loss of valuable archaeological deposits and thereby reduce subsidence.

Planning for a prosumer future: The case of Central Park, Sydney

Rapid convergence of utility and mobility solutions enabled by data and the Internet of Things is future-proofing economies around the world, delivering liveability, sustainability and resilience, and importantly decreasing pressure on utility bills and infrastructure costs. Australians cannot miss out on the many benefits brought to families and businesses by the digitisation of infrastructure and services, not just reduced household bills but also the ability to generate income as prosumers, not consumers. Localised sustainable Next-Gen infrastructure and services are growing from within communities, creating a new class of consumer-the prosumer: where customers are more than consumers but also producers. Prosumers have the ability to generate free energy from the sun at home or office and sell the excess, recycle water and waste reaping the financial benefit, avoid the second largest household expense of a car by sharing mobility, and access shared data networks to plug in and play at little cost. Planning frameworks play a critical role in enabling a new utility prosumer future in Australia and reform of planning gateway processes is essential. This article highlights Sydney’s Central Park as a best practice urban infill development showcasing how the flows of water and energy are organised to provide enhanced sustainability, liveability and resilience for the local and neighbouring communities. Central Park proves the benefits of taking a precinct approach to utility and mobility services. It shows how these benefits can grow and be exported to neighbouring buildings and existing communities, in this case University of Technology driving inclusion and affordability. Central Park also demonstrates the opportunities to drive deeper socio/environmental benefits by enabling prosumer services through low-cost access to utility services and circular resource flows. Importantly, this article demonstrates that Central Park’s phenomenal sustainability benefits can be replicated at scale in land release communities, but planning reform is required.

Capturing Urban Memory with Sentient Data, Counter Mapping and Digital Methods

This paper puts forward a conceptual proposition that ties the discourses on ‘urban memory’ (Stillman and Johanson, 2009; Ringas, Christopoulou, Stefanidakis., 2011; Loughran, Fine & Hunter, 2015), sensory ethnography (Pink 2017 ), and counter-mapping (Crampton and Krygier 2018; ) with digital methods (Rogers, Sánchez-Querubín, and Kil, 2015). As an ‘interventionist’ approach, we understand co-producing counter (dynamic) maps with local stakeholders (actors), coupled with sensory and sentient data as a way of capturing the memory of urban peripheral landscapes (through intervention and participation) and thus creating archival knowledge.Urban memory is often understood as a form of collective memory that isconstituted by individual experiences within the place itself and through its historyand social environment (Ringas et al., 2011). With rapid changes in digitaltechnologies, digital and material have become “inseparate and entangled inenvironments people move and navigate their lives through'' (Pink and Fors, 2017).Memories are “evoked with material engagement with devices” which “opens up afield of sensory and affective engagement” research (ibid). While Pink and Forspropose to follow such engagement in a mundane and everyday setting, seen as anon-representational, phenomenological approach, we put forward a mixedmethods approach that connects sensory and sentient data (as agents) with the largerenvironmental context.Urban areas are often conceptualized as sites of ‘creative destruction’, in between stability and change, space (that can be developed) and place (that is lived in), often subjected to planning, regulation, and economic forces (Batty, 2007). This is especially true for urban areas that are located outside of the ‘center’ or in the cities’ periphery. These areas have experienced an endless cycle of deconstruction and reconstruction often witnessed and captured by local inhabitants, creatives, and activists. Currently, many of the peripheral areas are emancipating, bringing forward and openly communicating their complexities, values, and engaging various stakeholders in their regeneration efforts (which happens in a broader context of many European cities repositioning themselves in more polycentric and polyphonic ways, (Scott, 2015).To be able to capture the memory of ever-changing, ‘built a new’ urban places, we put forward counter (dynamic) mapping using digital methods as complemented with sensory and sentient data generated through interactions with digital technologies. Building on Crampton’s notion of maps (Crampton and Krygier, 2018), cartography is understood as existence (becoming) rather than essence (fixed ontology). Maps are therefore taken not as ‘objects’, but as performative practices. Digital methods, on the other hand, enable us to understand dynamic place-making, through ‘tracing’ the stakeholders (actors) and their relations overtime to capture the ways the urban environment gets performed.To clarify with an example, in Spinoza Imaginaries Lab & Cafe situated inAmsterdam Southeast we have been capturing the ever changing urbanenvironment in partnership with local stakeholders (actors), mapping their evolvingrelationships (and grouping) using the IssueCrawler and sentient data co-gatheredby researchers and students, with the clear understanding that to be able to capturea place, it is important to map the vernacular knowledge of that place (imaginaries,including art, movies, unrealized plans and initiatives, etc.). We propose this mixedmethods approach as an epistemological practice geared towards archiving thedynamic state of urban peripheral landscapes.

Impact of student interventions on urban greening processes

The aim of this study is to determine the contribution of student interventions to urban greening processes. In two Dutch cities action research was conducted, including reflexive interviews a year after the first intervention, to assess factors causing change in the socio-ecological system. Results show that students and network actors were mutually learning, causing the empowerment of actors in that network by adding contextualized knowledge, enlarging the social network, expanding the amount of interactions in the socio-ecological system and speeding up the process. Students brought unique qualities to the process: time, access to stakeholders who tend to distrust the municipality and a certain open-mindedness. Their mere presence made a difference and started a process of change. However, university staff needed to keep the focus on long-term effects and empowerment, because students did not oversee that. After a year, many new green elements had been developed or were in the planning phase. In Enschede, the municipality districtmanagers were part of the learning network, which made it easier to cause changes in the main ecological network. In Haarlem however, no change took place in the main ecological network managed by the municipality, because no political empowerment of the civil society group had developed yet.

The Urban Heat Atlas

With increase in awareness of the risks posed by climate change and increasingly severe weather events, attention has turned to the need for urgent action. While strategies to respond to flooding and drought are well-established, the effects - and effective response - to heat waves is much less understood. As heat waves become more frequent, longer-lasting and more intense, the Cool Towns project provides cities and municipalities with the knowledge and tools to become heat resilient. The first step to developing effective heat adaptation strategies is identifying which areas in the city experience the most heat stress and who are the residents most affected. This enables decision-makers to prioritise heat adaptation measures and develop a city-wide strategy.The Urban Heat Atlas is the result of four years of research. It contains a collection of heat related maps covering more than 40,000 hectares of urban areas in ten municipalities in England, Belgium, The Netherlands, and France. The maps demonstrate how to conduct a Thermal Comfort Assessment (TCA) systematically to identify heat vulnerabilities and cooling capacity in cities to enable decision-makers to set priorities for action. The comparative analyses of the collated maps also provide a first overview of the current heat resilience state of cities in North-Western Europe.

Reorganizing city logistics to reduce urban movements

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.
