City x Space: Cross-Section Thinking

How can the integral and multifunctional use of public space, subsurface, and buildings -within a densified urban environment – create space and value that contribute to an attractive and future-proof living environment?

“This seminal question generates various answers depending on the specific context and location of asking. International interdisciplinary students from Delft University of Technology have outlined various design solutions. Manifest in all cases are the spatial bottlenecks on the level of public space. Connecting the intervention areas with the surrounding socio-spatial networks therefore forms the basis of all solutions. In addition, in the densification challenges we see the attention for the multi-layered space: on the one hand, a train or metro station, for example, generates flows of people at several levels; on the other hand, building in higher densities and/or living and working in collectives, generates new shared spaces.” As Maurice Harteveld explains in the exhibition; “The hybridization of the urban and architectural program also requires a cross-section thinking. This can be seen in future-proofing both large-scale sports or industrial areas, as well as small-scale residential houses in neighborhoods where work is shifting to local entrepreneurs and home workers. Finally, the subsurface plays an important role in greening the living environment and in water storage.”

500 Days at Home

“After working from home for more than five hundred days, our daily lives and rituals have been severely changed by the COVID-19 pandemic. Moreover, social distancing and other measures have affected everyone’s access to public space and exposed a range of impacts on different levels. Researchers from more than twenty universities explore those impacts in the new open-access publication ‘2020: A Year without Public Space under the COVID-19 Pandemic’.

The crisis in early 2020 immediately brought together the global community of experts on the design of public space. Maurice Harteveld (Urbanism) is part of the scientific board of the Journal of Public Space and distinctly remembers how the initiation of lockdown upon lockdown sparked debate: “Chief editor Luisa Bravo was already in lockdown in the north of Italy, another colleague soon followed in Hong Kong. The progressively worsening health situation led to images of abandoned public space. We started to share local insights, forming a global perspective on the issues arising from the pandemic for the current situation of public space. By connecting with UN-Habitat, the United Nations Human Settlements Programme, this became an opportunity to re-think how cities should be.”Deserted public space in Rotterdam, the Netherlands.

Health Disparity, Public Space Restrictions and the Future of Public Space
Shared online initiatives resulted in experts from across the world exchanging experiences of care, solidarity, entrepreneurship, academic perspectives, artistic interpretations, and creative practices of human resilience. The resulting key learnings from the early stage of the pandemic are encapsulated in the publication. The research addresses questions like how we can prepare for the consequences of this unprecedented emergency, particularly health disparity, but also addresses the impact of public space restrictions. More generally, the learnings reflect on what the future of public space might be.

At first glance, the challenges for each urban region might look different. Harteveld: “I vividly remember how Casper Chigama, a community developer from Zimbabwe gave an online presentation from his car, addressing how the local concerns there were about how social distancing might be achieved in the short term. But in the long term, pre-existing concerns on urban hygiene were the main challenge. Another colleague from New York City, Setha Low, mentioned how, even with urban hygiene relatively well organised, she still noticed disparity in access to qualitative public space between different population groups of the city.” In the end, the solutions to these challenges might lie within the same realm of making public space more recognisable on a local scale. People should not only have access to public space from their own homes, they should also be able to identify themselves with these places. “We stay closer to home, shown by trends like the increase of working from home and online shopping, and the consecutive decrease of commuting and going to the city centre,” explains Harteveld. “We clearly saw this in 2020, but the trend already emerges in the 1980s. Today, that means we need to be able to feel at home within the public space. As designers and planners of urban space, we can actively contribute to the detailing and programming of the public space to make such attachments possible.” Harteveld calls this the ‘domestication’ of public space. Fellow researchers observe the same, also at places where urban hygiene and inequality is of urgent concern. Josephine Mwongeli Malonza mentions for example how neighbourhood streets function as public space in Kimisange, Rwanda. The future of public space is local, equitably accessible, and very much an interesting and continuing challenge for urban designers, planners, legislators, and other city dwellers.”

Domestication Will Shape Future Public Spaces
A Report from Rotterdam

This commentary aims to provide a window on the future by studying actions, taken to control the spreading of the coronavirus, while obviously affecting public space over a year. What have been the effects on public space directly linked to these actions during the pandemic; what values play a role, and what can we expect for the future? We have seen how immediate responses induced by the COVID-19 crisis influences traveling, gathering, and public life in general. Now, it is time to look further. Having a base-point in Rotterdam and taking The Netherlands as an example, the commentary argues that some shifts in using, appropriating, and experiencing public space will remain. Yet, mainly
those not just being immediate responses to sudden societal change, rather those which
are embedded in long-term change.

2020: A Year without Public Space under the COVID-19 Pandemic!
new publication of The Journal of Public Space

The Journal of Public Space published ‘2020: A Year without Public Space under the COVID-19 Pandemic’. This monumental publication of 280 pages witnesses the year we all lived on social distance dictated by COVID-19 health emergency, a measurement severely affected everyone’s access to public space and with it creating a range of impacts on different levels. Delft University of Technology, as a worldwide recognised leader in the field of urban design and public space, united with more than twenty universities globally to question; how can we face this unprecedented emergency and get prepared to its consequences, with specific regard to health disparity? Will public space restrictions stay in place after the recovery period? Should we just aim to return to a pre-COVID status quo, or for a ‘better normal’? And more generally, what will be the future of public space?

Maurice Harteveld, part of the scientific board, remembers how the situation induced by the COVID-19 crisis in early 2020 immediately brought together the global community of experts on the Design of Public Space; “I remember how the alarm bells didn’t stop anymore in the third week of April. Health situation worsened progressively in China, and a new decree imposing quarantine became in act in Northern Italy. Public space was abandoned there. Without doubt, we started to share local insights and form a global perspective on the issues arising from the pandemic for public space the current situation of public space.” Together with UN-Habitat, the United Nations Human Settlements Programme, this became an opportunity to collaborate to re-think how cities should be.

As the pandemic was moving across different continents and urban conditions, through shared online initiative public space experts across the world exchanged experiences of care, solidarity, entrepreneurship, academic perspectives, artistic interpretations, and creative practices of human resilience, engaging more than 100 speakers during 20 webinars from May to September 2020, and more than 2,700 registered attendees from over 80 countries, including representatives from UNHabitat. Global impact of the online initiative ‘2020: A Year without Public Space under the COVID-19 Pandemic’ has been even broader by counting more than 72,000 page views in that same period. This publication encapsulates key learnings globally from the early stage of the pandemic, which stand relevant to this day when we face squarely the same issues as we step into gradually and navigate the post-COVID era.

Matter – Space – Change

When reasoning our material world emerged in cities, ‘matter’ was first to question. This is obviously what we see and what we can handle. This shapes our urban environment. Yet, in an arcadian search for beginning, origin, or first cause the lens was put on finding primordial substance; ‘arché’ (oersubstantie, urstoff, …). This informed the search to actuating principles (as a cause) in Aristotle. The subsequent cosmic search towards the genesis and structure of our world introduced the concept of a material substratum, an interval considered to be invisible and unshaped: ‘khôra’, chora, or space. The territory of the Ancient Greek polis outside the city proper. In Politeía, Plato relates it to the just city and just (hu)man. In these pioneering thoughts, public space is found. Continuously echoing today in understanding chora as a place of being a being or mediating between sensible and intelligible, it also introduced change… Public space isn’t static. People move, societies transform, humans age, generations follow…. This effects our thinking on public space.

Public Spaces for Domestic & Local Life

While the ‘UN-Habitat State of the World Cities Report 2020 on the Value of Sustainable Urbanization’ has been launched, the international symposium ‘2020 A Year Without Public Space: Reflection and Outlook’ has been an opportunity to look back, reflect, and plan ahead for 2021.

The transcription of the closing remarks of Maurice Harteveld at our initiative ‘2020 a year without public space under the COVID-19 pandemic’, including reflections and an outlook beyond (online symposium on 7 November 2020, 3PM (+ 8UTC)):

2020 – A Year without Public Space has been an impressive initiative. We have seen 20 webinars, engaging more than 100 speakers all over the world, and over another thousand attendees watching the presentations and thematic discussions live. On the YouTube channel, we can see that the numbers of views continuously grow. From May to September; the global community of ‘public space’- experts have joined together. The networks of public spaces have become a world-wide-web. Non-Exclusive!

At the moment, we are online, but our concerns are at the human space, in its physical reality. We keep sharing our observations, in an immense challenge. It is not easy! Under the current pandemic crisis, the global death rate is approaching 1.5 million people; 50 million cases of positive testing. An extremely small minority of countries have not reported any coronavirus cases. Kiribati, Nauru, Palau, Samoa, Tonga, Tuvalu, and Vanuatu seem to be still on the safe side. In contrast, particularly, communities in urbanised areas are infected at large. LA, Miami, and New York City… Rio, and Sao Paulo. Here densities are higher, people live closer together, and thus, transmission may go too fast, & too easy.

My contribution to the round table discussion is not another presentation. Deliberately! Continue reading

Creating Value through Public Space

The United Nations just launched the ‘UN-Habitat State of the World Cities Report 2020 on the Value of Sustainable Urbanization‘. “COVID-19 has transformed our urban world. However, it does not signify the end of cities. Urban areas hold the key to resilient, green recovery, and building back better!”, Victor Kisob, th assistant Secretary-General and Deputy Executive Director of UN-Habitat states. The United Nations emphasises that we create “value through public space”. This includes interior public spaces, which were closed due to COVID19-induced lockdowns recently. In this case, “local governments must work to provide sanitation infrastructure in all public spaces in order to mitigate the health risk”. Yet, also, “when designed with climate adaptation, mitigation and resiliency, components of cities from buildings to public spaces can create communities that enhance environmental values”. They also enhance social and economic values. “Cities can unlock the intangible value of sustainable urbanization by creating public spaces and opportunities for democratic participation and social inclusion that allow the cultural fabric of urban life to flourish”. And, public space can offer a livelihood for people to be entrepreneurial and take part of labour work. Equality plays a huge role in sustainable urbanisation. “Diversity contributes to the social, economic and environmental value of urbanization through tolerance, integration, and coming together in public spaces.” This includes for instance the representation of the urban poor, migrants, and cultural minorities, hence this should lead to prioritising “their needs in any decision-making process, be it about the urban commons, atmospheric commons, public spaces or resource use”. And, “engage a wider audience – e.g. children and youth – in urban planning and design processes for safe, inclusive and accessible public space.” Everyone should “understand their rights to access public spaces and services”. I would like to add: Our challenge is to contribute to the design of public spaces for everyone.


World Cities Report 2020

Domestic Public Space

If the current period teaches us, as colleagues, anything explicitly, it is that we must take account of a changed way of thinking on public space and housing. This shift presents us with a major challenge when it comes to further densification of the city. The existing urban fabric needs revision, even in areas where there is no increase in density. Public space is becoming more homely, and houses are becoming workplaces, so partly more public. We will pay more attention to the immediate living environment: the space in the vicinity.

Re-Learning Public Space

An Action Research Event

When: 28th – 30th June, 2018
Where: AMS Institute, Mauritskade 62, 1092 AD Amsterdam

Urban researchers, planners, communication experts, geographers, architects, as well as active citizens, policy makers trace the stories behind contemporary appropriations of public space. They identify related dilemmas and formulate research questions by liaison with locals, designing an alternative city guide inspired by a set of broad, yet timely themes: The ludic team focusses on the affordance of creative reuse an play in the city, grounded in co-creating public space. The circularity team focusses on self-sufficiency in the city, as manifested by places of gathering and sharing and tangible in productive urban landscapes. The informal team focusses on emerging inequalities and politicisation/de-politicisation, as a result of global commons and local governances of urban places. The wild life team shifts focus to the place of animals in our city. The mass tourism team shines the light on the effect of visitors, travelers, and short-stay residents on the public sphere.
