Retaining industrial heritage publicness : The interrelationship of industrial heritage and public space
No full textGame changer? Planning for just and sustainable urban regions, Paris, 8-12th July 2024This research aims to explore how to use interrelationship of industrial heritage and public space for making a city with public industrial heritage. In the UK and especially in London, the industrial heritage is gradually becoming a private profitable property rather than being used as historical knowledge for the public. To retain the publicness of industrial heritage, this research uses public spaces as a platform for industrial heritage presentations, examines how the industrial heritage shapes and influences the public space, and in what way the public space reflects and responds to the public value of industrial heritage in the transformation process. The research finds that the interrelationship of industrial heritage and public space can be enhanced and created by intervening on the public space visually, socially and physically. Therefore, three specific strategies of different aspects are proposed to enhance the interrelationship and further to present the publicness of industrial heritage.

Assessing regional potentials for green hydrogen infrastructure planning in Germany
No full textGame changer? Planning for just and sustainable urban regions, Paris, 8-12th July 2024Green hydrogen offers significant advantages in terms of sector coupling and electrification of energy systems. To ensure a reliable hydrogen supply chain in regions, there is a growing need for hydrogen infrastructure planning. Strategies need to take into account spatial characteristics of supply and demand as well as existing regional potentials. The aim of this study is to develop a holistic approach to assess regional potentials in the context of green hydrogen infrastructure planning by considering both technical and socio-economic factors. A principal component analysis was carried out in NUTS-3 regions throughout Germany. We identified four indices representing regional hydrogen and location potential. A cluster analysis was used to identify region-specific needs and requirements. This will benefit the planning process for developing regional hydrogen strategies.

A Study on the Path of Enhancing the Social-ecological System Resilience in Shrinking Small Towns in China
No full textGame changer? Planning for just and sustainable urban regions, Paris, 8-12th July 2024In 2022, China experienced its first population decline in decades, leading to an increasingly common phenomenon of urban and rural shrinkage. Small towns, under the dual pressures of the suction effect from larger cities and rural revitalization policies, face elevated development risks. This paper proposes pathways to enhance the resilience of the social-ecological system of shrinking small towns through the territorial spatial planning. These pathways include enhancing buffering capacity both within and beyond urban development boundaries, strengthening self-organisation at all levels, and improving learning capacity through dynamic assessment and adjustment. The aim is to proactively mitigate the risks faced by shrinking small towns, improve residents' quality of life, and offer insights for China's high-quality urbanization development and governance.

Study on the Evolution Characteristies and Collaborative Governance Strategies of “Production-Living-Ecological" Space at county level in Loess Hills and Gully Areas--Taking Huangling County as an Example
No full textGame changer? Planning for just and sustainable urban regions, Paris, 8-12th July 2024With China's rapid economic development and continued urbanisation, the contradiction between urban expansion and land resource use has become increasingly prominent. The study site is located in the gully area of the Loess Plateau, where soil erosion is a prominent problem. The acceleration of urbanisation further complicates the spatial contradiction between production, life and ecology. In the context of ecological civilisation construction, it is crucial to study the spatial evolution of production-life-ecology in the county. The study indicates that the production space in Huangling County is fragmented, the living space is inefficient and the ecological space is fragile. Consequently, a comprehensive management strategy to protect the production space, optimise the living space and regulate the ecological space is proposed.

Innovative Tools For Building Child-Friendly Communities: The Development And Application Of Child-Friendly Neighbourhood (CFN) Built Environment Audit Tools, Insights From Shanghai
No full textGame changer? Planning for just and sustainable urban regions, Paris, 8-12th July 2024Neighbourhood environment is an important carrier of children's daily activities, but traditional urban planning and design often ignore the impact of micro-scale built environment on children's environmental perception. In the central urban area of Shanghai, which is characterised by high-density human settlements, integrating childfriendly concepts to carry out community renewal requires more consideration of the actual basis and renewal results. This study innovatively developed a "Child-Friendly Neighbourhood (CFN) Built Environment Audit Tools" that can systematically evaluate the micro-spatial elements in the three types of spaces within the 5-10 minute living circle of the community, including community streets, outdoor public spaces, and residential environments, to finely identify community space problems and help formulate special renewal plans for childfriendly communities.

No full textGame changer? Planning for just and sustainable urban regions, Paris, 8-12th July 2024Highly condensing the value and characteristics of urban and rural historical and cultural resources in Qinghai is crucial for building a preservation system. This study, focusing on Qinghai, excavates its value themes and summarizes its historical development's core values. Leveraging geography, history, and GIS, it analyzes cultural origins, lineages, and theme condensation. Integrating planning, heritage, and spatiotemporal development, 27 value features are extracted from politics, economy, society, science, culture, and geography. Ultimately, Qinghai's "Four Area" core value is condensed. This study aims to offer insights for recognizing the province's urban and rural cultural value and utilizing cultural heritage.

Innovations in Semi-Formal Tools and Multi-actor Cooperation for Urban Design Governance: The Practice of City Chief Designer System in China
No full textGame changer? Planning for just and sustainable urban regions, Paris, 8-12th July 2024Urban design governance is the process of state-sanctioned intervention in the means and processes of designing the built environment in order to shape both processes and outcomes in a defined public interest, advocating for the establishment of a system of actions and decisions composed of diverse entities. The current development trajectory of Chinese cities has shifted from a period of rapid growth to a phase of high-quality development focusing on stock space, and urban design as a mode of planning and control has received more and more attention. A new form of urban design governance has emerged in key areas of development in some mega-cities—the City Chief Designer system. The City Chief Designer system serves as a semi-formal governance tool, bridging the gap between the hard-power governance of government authority and the soft-power governance of nongovernmental organizations. This study divides the development of City Chief Designer system into three stages: the implicit development period, the establishment of the mechanism period, and the optimization and adjustment period. It summarizes the practical role of the system in driving the effectiveness of urban design operations, and investigates the interactive relationships among diverse participants. The study dissects the role of the system as a semi-formal design governance tool, analyzes power shifts and institutional reforms, and discusses the problems of the system, aiming to provide insights for optimizing the governance system of future urban design.

The Open Orchestra project in the public spaces of Athens: an urban utopia with transformative power?
No full textGame changer? Planning for just and sustainable urban regions, Paris, 8-12th July 2024The Open Orchestra is a group of about 150 professional artists and amateurs, founded in spring 2021, in Athens, Greece. Its establishment is directly correlated to the Support Art Workers Action Group that has emerged during the pandemic of Covid-19, as a way to resist to the depreciation of culture and art-workers themselves, many of whom remained unemployed and with no support from the state, during the long quarantines imposed as a protection measure1. Even more importantly, the Open Orchestra comes as a continuation of the Paris Occupation of Odeon, when, on March 27, 2021, during the Agora organized by the occupants of the Théâtre de l'Odéon, professionals from the French Symphonic and Lyric Orchestras, musicians from specialized orchestras, occupiers of the Odéon, and students formed a large orchestra of solidary musicians2. Following this line, in spring 2021, the Support Art Workers Action Group gathered in Propylaia, Athens, sang and played the piece “El Pueblo Unido Jamas Sera Vencido”, exactly as did the solidary orchestra at Odéon, Paris, a couple of months earlier. This has been the starting act of the Open Orchestra (O.C./ A.O. in Greek). Which started rehearsing once a week, at the Filopappou Hill, in a central public park of Athens, yet derelict and merely abandoned by the Municipality of Athens. It is called Open Orchestra, because anyone who wants to rehearse with it can do it at any time: there is no limitation on artistic level or degree of commitment (one can enter and leave the Orchestra at any time). Organizationally, there is a solid core of 100 people, who rehearse every Sunday. There exists a coordination group, yet decisions are made through open circles organized regularly, in which the whole group participates. This is particularly relevant to the organization of different projects. Every one or two months, rehearsals take place in a deprived neighbourhood of Athens (Victoria square, Perama, Amerikis Square3, etc.), instead of the regular one at the Filopappou Hill, and messages such as “Lively Squares” or “We want to danse in squares, streets and neighbourhoods” are delivered in any possible means (e.g. banners, posters, etc.). The A.O. also gives an open concert every June, in vicinity to the archeological site of Kerameikos and the Acropolis. Yet, most importantly, it provides solidarity to several people and events: performances in several trials of public interest (trial for the murder of Zac/Zackie4; trials for victims a sexual violence, rape5 & murder; etc.), as well as campaigns for social justice and peace, with the most recent example concerning the war in Gaza and Palestine6. The aim of this presentation is to explore how this impulsive bottom-up initiative can/has become “game-changer” at the local (city) and the very local (neighbourhood) level, essentially as an antidote to the harsh regeneration and touristification policies that hit actually the Greek cities. Building upon my own participation to the A.O. during 2021- 2022, I seek to understand to what extend such an initiative – a community of joy, care and solidarity, and an urban utopia, as I would like to call it – may be capable of transforming, in the mid-term, both public space and the relations performed within public space. Considering its ephemeral and sporadic performances and actions, to what extend can an initiative such the A.O. play a role in shaping the neighbourhood and the city fabric overall? I am particularly interested in examining the potential of such initiatives yet also the significant challenges they pose as regards appropriation, belonging, and reclaiming the city. After all, what would be needed, from a planner’s perspective, to enhance and leverage such initiatives in a view of coming closer to the ideals of the Just City and the Right to the City? How can planners ensure that such bottom-up initiatives can be taken under consideration in decision-making processes? What kind of spaces could accommodate such initiatives that promote interaction among diverse people yet often they challenge the established status quo?

Strategies to mitigate the urban heat island effect in Mediterranean promenades of France, Italy, and Albania
No full textGame changer? Planning for just and sustainable urban regions, Paris, 8-12th July 2024Cities are currently confronting with a variety of challenges stemming from climate conditions, urbanization, and urban planning, resulting in increasing social, health, and economic issues. This study specifically examines the Mediterranean coastline promenades in Albania, France, and Italy as a unique type of built environment. The aim of this study is to examine the influence of different cooling system scenarios on the thermal comfort experienced by pedestrians, while considering climate data. We generate multiple scenarios by analyzing ways to mitigate urban heat island (UHI) effects. These strategies include revitalizing promenades by replacing current pavements, utilizing water bodies and sprays, increasing the presence of artificial shade, considering the proper greenery, and implementing advanced cooling systems using smart technologies.
