UrbaRiskLab

Lucie Leprince — Thu, 08 Jul 2021 14:07:45 +0000

LATTS researchers: Valérie November (project director), Alice Azémar (project manager)
Alexandre Geffroy: website updates and data analysis
Other LATTS researchers involved: Stève Bernardin, Kostas Chatzis, Geneviève Zembri

Funding: French National Research Agency (ANR), via the I-SITE FUTURE special grant

Duration: 4 years (2018-2022)

Academic partners outside LATTS: around 100 researchers, mainly from Gustave Eiffel University, but also from other institutions (Telecom Paris, Paris-Dauphine University, Mines d'Albi, etc.)

UrbaRiskLab (URL) is a project that aims to create a multidisciplinary center on the theme of risk/crisis in urban environments. It was founded on the observation that all crises (whether natural, climatic, chemical, pathogenic, economic, cyber, societal, etc.), whether planned or unplanned, exceptional or chronic, slow or fast-moving, generate significant scientific, technical, organizational, and political uncertainties. They raise crucial questions in terms of preparedness, monitoring and detection, modeling tools, anticipating cascading effects, emergency response, decision support, and post-crisis management. Taking an interdisciplinary approach to the dynamics of risks and crises in urban environments is a scientific challenge that must be addressed in order to provide strategic, political, technical, economic, and social responses to these problems and make cities safe and resilient. URL was designed as a research center offering innovative, multi-risk, multi-scale thinking and solutions that represent a technological breakthrough. From the outset, the project was designed to be scalable and experimental.

The process of creating the multidisciplinary center required several steps: on the one hand, a bottom-up approach to analyzing the expertise available within the consortium. URL brings together around 100 researchers from more than 30 different disciplines who, together, offer expertise and scientific coverage of all categories of risks affecting urban areas. Thus, without listing them exhaustively, natural and environmental risks, climatic and meteorological risks, risks related to infrastructure and technical networks, health risks, risks related to social inequalities, risks related to major events and crowd movements, and road safety issues are an integral part of the research carried out within the consortium. The project draws on expertise in the hard sciences (applied mathematics, statistics, geosciences, analytical chemistry), engineering sciences (mechanics, biomechanics, civil engineering), environmental sciences (hydrology, hydraulics, metrology, new sensors, (eco)toxicology) and social sciences (sociology, geography, urban planning, economics, management sciences, architecture, psychology).

While mapping the skills available within the consortium, URL has developed a methodological framework to encourage the creation of interdisciplinary projects. As an experiment, "MiniLabs" were set up to function as "research incubators" within the project. They are run by pairs of researchers from the SPI and SHS. Their titles cover a wide variety of risks and disciplines and provide food for thought across the board. There are currently four of them:

The "Data Analysis and Processing" MiniLab focuses on the two overarching issues of data optimization and reliability. It also reflects on how to measure the uncertainty generated by unreliable data.
The "Sensors and Uses" MiniLab focuses on innovative sensor technologies, automated data processing, and new societal uses.
The "Visualizations" MiniLab focuses on the extraction and exploitation of information (textual and image), the representation of complex data, and the design and co-creation of interfaces with end users.
The "Information Circulation in Adverse Conditions" MiniLab focuses on the need for and quality of data for target users, problems with interpreting and transferring information in crisis situations, and even the societal impact of degraded information (fake news, etc.).

Resilience in the face of a global and systemic crisis: the case of the SARS-CoV2 coronavirus pandemic

Lucie Leprince — Fri, 04 Dec 2020 07:38:01 +0000

Postdoctoral project by Rina Kojima funded by the National Center for Resources and Resilience (CN2R) and supervised by Valérie November.

This research project, at the crossroads of sociology, geography, and psychology, aims to study the "spatio-temporal trajectories" of people—whether sick or not—affected by the SARS-CoV2 coronavirus pandemic, as well as to revisit the notion of resilience in societies facing risk, uncertainty, and disaster. The objective will be to analyze how these individuals cope with and make sense of this historic and global event, as well as to investigate how these societies can improve their resilience in the face of this unprecedented systemic crisis, which has triggered heated scientific and political debates on all levels, including health, socio-economics, the environment, etc.

For this research on resilience, both individual and collective, I plan to examine the socio-cultural and psycho-traumatic consequences of this pandemic on younger generations, particularly students aged 18 to 25, by analyzing their "spatio-temporal trajectories" in three aspects:

1) mobility/immobility in the face of the risks associated with this crisis – leaving one's primary residence, staying there, or returning there in the short and/or long term,

2) the measures and representations of these risks, and

3) the relational problems associated with these risks.

In order to better understand the consequences of this global and systemic crisis, I therefore plan to conduct a comparative study in two countries with different cultures, namely France and Japan. This study will be based on a longitudinal field survey, through interviews with students residing in the most affected areas—Paris and Strasbourg for France, Tokyo and Sapporo for Japan—and will include follow-up to better understand the evolution of psychological trauma over time.

URBAN-REV POLITICS, The Urban Revolution and the Political.

Lucie Leprince — Thu, 17 Jan 2019 13:17:57 +0000

There has been a proliferation of discussions regarding the social and ecological implications of contemporary urbanization. Notions such as ‘urban futures’ and ‘urban age’ are evoked to highlight the urban nature of the ecological and societal challenges we face.

What is largely missing in these timely debates, however, is a systematic and in-depth engagement with the political significance of the ongoing "urban revolution"—a term coined by urban sociologist Henri Lefebvre in 1970. Building on his work, a few scholars, such as Neil Brenner and Christian Schmid, have elaborated on the territorial and socio-spatial aspects of planetary urbanization, namely the increasingly uneven, complex, and polycentric nature of the urban at the scale of the entire planet. But the question of politics is still treated tangentially. Is there a particular kind of urban politics corresponding to our urban age? Do we need to rethink the way in which we govern our cities, the common resources that cities offer? Is international investment in real estate beneficial for cities?

To answer these questions, we first need to develop an understanding of the increasingly dominant urban-based accumulation practices. There are indications that speculation on land and real estate is becoming increasingly global. Multinational real estate companies and investors that operate on a global scale have important consequences for cities.

URBAN-REV POLITICS approaches global urbanization and its contestations from the perspective of the production and consumption of the built environment. Using a political economy approach, it seeks to understand wealth generation strategies based on the production and consumption of urban space and specific urban transformations that they underpin, as well as how these are negotiated and challenged at the local and global scales.

The project is organized around three interrelated themes corresponding to three sub-projects (work packages):

The first is the uneven globalization of real estate markets. Here we trace the interactions between various influential public and private actors (investors, asset managers, brokers, real estate developers, politicians, decision-makers, etc.) to understand how their decisions and actions have impacts in specific sites.

The second is the exploitation of urban space through rent extraction. Here, in relation to the first subproject, we examine how a profit-driven approach informed by various risk-return calculations and negotiated with local authorities affects urban spaces.

The third is the ways in which these often highly speculative interventions in urban spaces are negotiated and contested at different scales. We examine both the formal sphere of politics as well as contestations by civil society groups.

Using a multi-sited ethnography approach, the work is based on Istanbul, London, Paris, and São Paulo. These cities feature comparable processes of property-led (re)developments, and a variety of activist and advocacy networks that challenge these.

URBAN-REV POLITICS seeks to contribute to debates in the fields of urban planning, urban political economy, and economic geography. Many of the themes we engage with, such as urban redevelopment, competition between cities, gentrification, and urban social movements, are the focus of significant scholarship today. Other themes discussed, such as speculative urbanism, urban land rent, the finance-real estate connection, and the urban commons, have recently begun to attract (in some cases renewed) attention. However, these discussions tend to occur in a rather compartmentalized fashion. For instance, property-led urban redevelopment and gentrification are rarely discussed in relation to the transnational sites and networks of negotiation between state, finance, and real estate actors. Similarly, work on real estate studies does not sufficiently engage with issues related to conflict and contestation. The overall objective of the project is to offer a transnational and comparative account that not only ties these threads together in a coherent manner, but also offers an empirically substantiated framework for understanding the political implications of global urbanization.

Cross-functional group "Inventing Greater Paris"

Lucie Leprince — Fri, 07 Dec 2018 07:39:35 +0000

Created in 2012, the "Inventing Greater Paris" collective was formed around the scientific organization of a series of four annual symposiums (from 2013 to 2016) dedicated to the history of Greater Paris development in the 20th century, illuminated by international perspectives. The collective brings together researchers who use history to understand the modalities and challenges of metropolitan construction. It brings together specialists in the history of development, urban planning, and architecture, as well as urban, social, and institutional history and urban metabolism. Launched in 2017, the collective's website is a place for publishing the work contributed to the Inventing Greater Paris program, a portal for hosting future research, and a guide to historical resources. It is intended for a wide audience, including stakeholders and specialists. In 2018, the Inventing Greater Paris collective was formed as a Transversal Group of the Labex Futurs Urbains (University of Paris Est) and, as such, receives state aid from the Program for Investments in the Future.

The research program of the "Inventing Greater Paris" transversal group now has three objectives:

To develop an overview of research on the history of Greater Paris and comparisons with other metropolises.
To encourage new scientific questions on urban and metropolitan history,
To compile an inventory of sources and memories related to the history of this metropolis.

Method
With this in mind, the scientific project of the newly created cross-disciplinary group is structured around several areas of work:

A bi-monthly research seminar dedicated to epistemological questions at the crossroads of disciplines that examine the history of urban planning. This seminar is supplemented by one or two more open study days.
Research projects carried out by dedicated teams; the main project focuses on the creation of a bibliographic, archival, and iconographic corpus relating to major development plans (for the period 1928-1960), which is currently being used to develop an atlas of Greater Paris plans.
An editorial project aimed at building a resource center on the history of Greater Paris by publishing conference proceedings, study days, and scientific articles; Publishing news about research projects.
A corpus (including iconographic material) for research purposes, i.e., one that can be explored using innovative methods.

Safety on construction sites: preventive measures and their implementation in a public works company

Lucie Leprince — Mon, 19 Mar 2018 14:44:44 +0000

Pascal Ughetto, Philippe Askenazy, and Frédéric Garcias, with Gilles Jeannot, Juliette Ducoulombier, Nicolas Klein, Anne-Sophie Maillot, and Jean Tharotte

Report for a public works group, Prevention Department, March 2019.

The research aimed to understand the mechanisms by which corporate occupational health and safety policies produce their effects in terms of accident rates and economic performance, but also encounter limitations that may, to date, remain relatively enigmatic to stakeholders. It was carried out by a multidisciplinary team (economics, ergonomics, management, and sociology) and combined a qualitative approach with quantitative analyses. The group's prevention policy has developed a number of tools that reflect its desire to organize safety: informing and raising awareness of risks, listing them in order to better avoid them, and combating risk-taking. This includes a database of near misses and various awareness-raising and incentive schemes. A network of quality, prevention, and environment (QPE) professionals is an integral part of this policy. The group's prevention policy explicitly relies on the conviction of managers at all levels, considering that without a deep-seated belief in the importance of prevention on the part of managers, a group policy would lack real leverage.

The research revealed several findings and results. As much as it is influenced by individuals, and in particular by the ability of agency managers to take ownership of this policy and demonstrate their commitment to it, the effective deployment of tools is also influenced by economic reasoning. Even with highly committed management, economic considerations can take precedence: this can be seen in the case of an emergency on a construction site or in order to obtain a contract, knowing that the client is not sensitive to prevention. In this company, as in others in the sector, the indicators and management control of the agencies and the group effectively place prevention in juxtaposition with economic considerations. Although they are informed and aware of the tools available for prevention, workers are keen to report situations where this policy seems to give way to more pressing imperatives, such as the speed of completion of a project, catching up on accumulated delays, etc. The decisive factor is that project planning integrates prevention primarily in administrative terms. The schedule, initially based on the study and invoiced costs, focuses on ensuring that the project is completed within the budget. It leaves it largely up to the construction site and its management to adjust to the actual conditions. However, the realities of construction sites are marked by the normal nature of uncertainty, recurring downtime, and emergencies. For the construction site hierarchy, which is directly involved in concrete situations where the tension between economics and prevention must be resolved, there is nothing simple about embodying and implementing prevention measures in a credible manner. QPEs also have a complicated path to find their position in the articulation between a policy whose rules are formulated in the abstract and concrete situations that challenge the compatibility between economics and prevention.

Multidisciplinary evaluation and environmental requalification of neighborhoods (EUREQUA).

Lucie Leprince — Tue, 28 Feb 2017 08:43:30 +0000

The EUREQUA project (Multidisciplinary Evaluation and Environmental Requalification of Neighborhoods) is an ANR (Sustainable Buildings and Cities) initiative launched by Sinda Haouès-Jouve of LISST (UMR 5193), which began in March 2012 and ended in February 2017 with an international symposium focused on "interdisciplinary and participatory approaches." This research brought together nine partners (LATTS, LISST, GAME, CEREA, ENSA/LRA, IFSTTAR, LEPD, ATELIER LION, IAU/IdF). It examines the challenges of environmental requalification of the urban living environment at the neighborhood level. The project adopts an original methodological approach based on a multidisciplinary team of geographers, sociologists, climatologists, atmospheric physicists, acousticians, and architects, in collaboration with urban environment managers. The aim was to understand how to develop a concept of environmental quality in the living environment that combines a renewed reflection on the materiality of the urban environment with sensitive and social approaches to the relationship with the environment.

Final assessment of EUREQUA

Smart City Seminar – Cycle 2 – PUCA-LATTS Seminar – 2017-2018

Lucie Leprince — Thu, 12 Jan 2017 10:32:16 +0000

In 2014, Puca launched an exploratory seminar on smart cities
. The aim was to hold five sessions to initiate a discussion involving researchers, stakeholders, experts, and laypeople in order to move beyond enchanted narratives and negative preconceptions about smart cities and make them a possible object of governance or, at the very least, a shared object of research.

After an introductory session with Antoine Picon, the first person in France to develop a theoretical framework on the subject, the seminar explored the links between smart cities and sustainable development
, what they meant for the "city of networks
,"
the democratic challenges
of data in the urban sphere, and finally its "outside"
and the opportunities it offered to think about and organize it differently.

There was no assessment at the end of this first cycle, but there was a conviction that the smart city was a substantial concept
, protean certainly, but more complex than evanescent, and that it could not be limited to the extension of the digital domain to the city, the pursuit of e-administration by other means, or the ultimate stage of neoliberalism in urban services.
Borrowing, of course, from these and other registers, but not reducible to any one of them, the "smart city
" manifests itself in a way that is not fully captured by the predictive and prophetic discourse that accompanies it. That is why it was decided to continue the exercise.

But while the first cycle was led by the Puca, under the direction of François Ménard and Jean Danielou, this second cycle is part of a more cooperative and partnership-based approach. LATTS (Laboratoire Techniques, Territoires et Société)
, a partnership between the CNRS, Ecole des Ponts ParisTech, and the University of Paris-Est Marne-la-Vallée, has offered to continue the project and suggest new areas for debate. How, beyond pilot projects and demonstrations, are the new opportunities offered by communication technologies, big data, and Web 2.0 transforming urban management and life
? How do these developments "enter" politics
, how do they influence policy, between under-politicization (by its actors?) and over-politicization (by researchers?)? This will be the theme of the first session.

The other sessions will address other questions: How
are knowledge production, urban sciences
, and the use of models influenced by the new possibilities of mass statistics
, by whom, and with what consequences? How is the economic landscape of urban services being redrawn (flexible uses, disintermediation, between platform economies and dynamic pricing, etc.)? Through what means
(open data, crowdsourcing, crowdfunding, digital forums, etc.) can these new technologies enable the population to influence urban management?

Without claiming to provide definitive answers from an expert perspective, the seminar aims instead to be a moment of shared inquiry into these emerging practices.

Session 1: "Smart city" policies, Friday, January 27, 2017

Session 2: Models and big data, Thursday, May 4, 2017

Session 3: Generalized transparency, filtering, or distortion: what big and open data reveal about the city

Smart Cities and changes in engineering

Lucie Leprince — Fri, 30 Dec 2016 12:54:58 +0000

Artelia Ville et Transport, an independent engineering group and technical expert in urban development, and the Laboratoire Techniques Territoires et Société, a multidisciplinary social sciences laboratory specializing in urban, regional and spatial issues, conducted a research and innovation project aimed at exploring the challenges of the smart city for French engineering between November 15, 2016, and December 5, 2018. Various working sessions brought together a think tank and discussion group with the aim of comparing perspectives on five themes: definitions of the smart city (1), governance of the smart city (2), economic models of the smart city (3), a historical perspective: lessons from electrification in the digital age (4), the materiality of the smart city (5).

Ultimately, exploring these five themes made it possible to shift the focus away from the initial question (relating to the transformation of engineering in the smart city), before returning to it with greater clarity in the conclusion and putting forward several avenues for further exploration. The mission showed that the smart city questions the temporality of projects. In terms of engineering, the construction cycle and the maintenance/management cycle are increasingly intertwined, which raises questions for engineering groups. What timeframe should be adopted? One example studied was that of digital data. What should be done with the digital data needed to carry out projects: return it to the project owners, manage it on their behalf over a longer period of time, or act as a data aggregator in the context of missions similar to public service delegations?

The mission also demonstrated the value of decision-making support tools that can be used by engineering in a context where digital technology generates a certain amount of uncertainty (regarding the purpose of initiatives, their cost, and their social and environmental effects). The cases of scenario planning and modeling, for example, were studied.

Finally, the mission made it possible to compare the organizational difficulties, directly or indirectly related to digital technology, that challenge public administrations with those faced by their partners.

Thematic school: National urban research outlook

Lucie Leprince — Mon, 09 May 2016 13:20:19 +0000

In spring 2015, the CNRS launched a national urban research foresight initiative,
which will result in several study days open to the entire scientific community until summer 2016.
The thematic school to be held in Aussois in September 2016
will conclude this collective reflection process, the results of which will be published in various
publications prepared in the fall of 2016 and winter of 2017, primarily in the form of a
collective work. The educational approach implemented in the thematic school will be designed
specifically with a view to producing this collective work.
The thematic school will be mainly based on the ideas gathered during
the six study days organized during the 2015-16 academic year: detailed reports,
texts of presentations, presentation materials, etc. A limited number of scientific articles,
to be read before the start of the thematic school, will complete this corpus.
The school program will alternate between workshops and plenary sessions for sharing ideas. It
will consist of two main phases:
– an initial phase of open collective reflection, aimed at identifying all
the topics covered and any important topics that may not have been
discussed, leading to the organization of these topics into a limited number of entries
(between twelve and twenty) intended to constitute the chapters of the collective work resulting
from the PNRU. This first phase will mainly take place in workshops, each bringing together
a dozen participants at most;
– A second phase will aim to develop, in small groups of three to five people, the
synopsis of each of the chapters thus defined. One or two people, primarily
from the PNRU organizing committee, will be responsible for producing a first
draft of the chapters.
The book and/or the various chapters will mention all contributors.
The entries corresponding to the future chapters of the book will mainly focus on
research topics that the collective reflection has identified as priorities
for the coming years. However, other contributions will, or may, focus on the
epistemological, methodological, institutional, or political issues of urban research,
or its relationship to action, always with a forward-looking perspective. Recommendations
more specifically concerning the programming of urban research may be
formulated.
The participation of doctoral students and early-career researchers from a variety of disciplines
covering all the major fields concerned (humanities and
social sciences, environmental sciences, engineering, health, etc.) is strongly encouraged. The
thematic school program will give pride of place to "radical" interdisciplinarity
between the humanities and social sciences and other disciplinary fields.

A longitudinal approach (1978-2013) to the national housing system using the ASHA model.

Lucie Leprince — Tue, 15 Mar 2016 09:28:03 +0000

The primary objective of this research is to understand the characteristics and developments of the current functioning of the national housing system over a period of thirty-five years. The aim is to develop a longitudinal approach by using the "National Housing Surveys" (ENL) conducted by INSEE from 1978 to 2013 in a comprehensive and systemic approach. This approach aims to measure the impact of housing supply on the redistribution of urban populations, taking into account the characteristics of the housing stock, mobile households, stable households, and chain effects. The processes and their effects will be studied using the "Habitat Systems Analysis" (ASHA°) model.
The second objective of the research is to improve the model in terms of both its usability (ergonomics) and its predictive robustness. This will involve working on:

ergonomics, in order to integrate new data output modes into the interface, visualizing simulations in the form of interactive graphs and tables suitable for comparative study,
segment modeling to take into account population aging at each iteration during simulations,
methodological developments to study the possibility of refining the model by reducing the "step" of each iteration during simulations.
the algorithm in order to improve the robustness of the model, to carry out a detailed study of changes in the national housing system, using a comprehensive approach, with the ultimate goal of proposing a robust model capable of simulating possible changes, blockages, and transformations over the next two decades.

Method
This involves using the National Housing Surveys conducted between 1978 and 2013, which contain information on the occupancy of the housing stock, mobility between segments of the stock, and entries from outside France. This application will enable a longitudinal analysis of changes in the national housing system (1978, 1984, 1988, 1992, 1996, 2002, 2006, 2013). The ASHA model will enable simulations to be carried out that reproduce the system identified in each housing survey (4, 6, or 7 years) by introducing future construction and demolition (informed by subsequent housing surveys), in order to verify the validity of the results through a possible comparison between surveys. This method should make it possible to analyze the evolution of the system and identify its mechanisms and potential blockages ("the housing crisis").
