congrès IGU-UGO Paris 2022The ESPI2R laboratory and the University of Paris are proposing two sessions on the field of real estate for the UUGI/IGU Colloquium from July 18 to 22, 2022.

For the urban commission (“Re-thinking Cities and the urban: from the global to the local”, chair: President: Piñeira-Mantiñán), a session on “Urban Dynamics and Real Estate” (coordinators: F. APPENDINO, J. BLAIN, A.-C. CHARDON and M. VIGNAU, ESPI group)
For the commission “Dynamics of Economic spaces”, president: Pr. Yavan), a session more oriented towards peri-urban territories, and entitled “Real estate and territories: where and how to build in a context of strong land constraint” (coordinators: S. DEPRAZ, ESPI group, and Renaud LE GOIX, University of Paris / UMR Géographie-Cités)

Abstract submission date: Tuesday, January 18, 2022.

Paper proposals can therefore be submitted directly online on the conference website until January 18, 2022. The abstracts will be evaluated by the coordinators and the results will be sent by January 21, 2022.

Public: PhD students, young researchers, real estate professionals, institutions, etc. and an international audience, with simultaneous French/English translation.

Session 1


Moderators: Federica APPENDINO, Jeffrey BLAIN, Anne-Catherine CHARDON and Mathilde VIGNAU

In March 2020, the first French containment related to the COVID-19 health crisis quickly brought to light inequalities and housing issues. In this sense, beyond an economic opportunity in the strict sense of the word, the real estate market seems to be a real geographical object that drives constantly changing territorial dynamics. Whether we look at it from the angle of transactions, long or short-term rentals (airbnb, uberization), asset management, the study of population movements, or the processes of densification and urban sprawl, real estate occupies a central place in the planning and development of territories, very often imposing a specific analytical grid.

In order to study this subject, the objectives of the session are multiple. First, it is a matter of analyzing – by mobilizing both French and international experiences – the major contemporary territorial issues that stem directly or indirectly from the real estate market. In this respect, it is appropriate, for example, to revisit the issues of residential mobility (“urban exodus”, second homes, etc.), housing accessibility (imbalances between stretched and unstretched areas, supply and demand, etc.), and the quality of real estate in the context of smart and sustainable cities (changes in construction techniques, home automation, greening, and effects on prices). These territorial themes are indeed the cornerstones of tomorrow’s cities. In addition, this session also proposes to identify the role of the main actors actively participating in territorial development through housing. To do this, the ambitions of many investors (public, private, foreign…) in real estate, must be analyzed. This point will allow, among other things, to determine the objectives targeted by several contemporary real estate projects (luxury real estate, territorial marketing, patrimonialization…). Finally, this session will offer the opportunity to deepen the problems of inequalities and socio-spatial injustices through the prism of housing. The aim is to show that, although these inequalities have existed for a long time, they have been exacerbated in recent years, particularly in the difficult and highly unequal context of the international pandemic (poor housing, insalubriousness, precariousness, maladjustment, etc.).

In order to respond to the many issues raised, the session will initially be structured in two slots (1h45 each), around the following four main themes: 1) Real estate at the heart of new residential dynamics, 2) Real estate and the sustainable city, 3) Real estate in the face of socio-spatial inequalities and finally, 4) The territory and real estate investors. These different themes, with a sufficiently open spectrum, offer a framework for reflection on territorial and real estate dynamics to a wide variety of respondents (researchers, students, professionals, institutions, etc.). International readings of the subject will be welcome and communications can be made in French, English or Spanish. If the health conditions allow it, the interventions of this session will be held in person.

Session 2

Real estate and territories: where and how to build in a context of strong land constraints?

Moderators: DEPRAZ, Samuel, Director of Research, Director of the ESPI2R laboratory, ESPI Group,

LE GOIX, Renaud, Professor at the University of Paris, UMR Géographie-Cités 8504 CNRS,

The global desire to reduce the territorial impacts of human activities has led, at least on a European scale, to a critique of land artificialisation and to a goal of “zero net artificialisation” by 2050 (EU, 2014). This context, marked by the ecological objectives of preserving biodiversity, strongly remobilizes other economic and social issues, particularly in terms of housing policy. Where to build in the face of land shortages and how to control prices to guarantee fair access to housing? How can we minimize the impact of land artificialisation, but also how can we define it more precisely and measure its progress? The indicators are still not stabilized, while the impacts vary depending on whether we measure imperviousness, ecological connectivity or the reversibility of construction processes. And how can the allocation of building land be regulated upstream? Is it possible to (re)come to a public control of a rare good?

This session therefore considers, on an international and comparative scale, applied studies on four precise dimensions of the problem, forming the four successive stages of the selected interventions: 1/ the comparison of ecological objectives with the social imperatives of housing demand, in order to identify the areas of greatest tension between ecological and social imperatives; 2/ a discussion of the varying rhythms and measures of the very notion of land artificialisation; 3/ a highlighting of the role of real estate actors (planners, developers, promoters, investors, property managers) in the financing and production of territories, valuation, and the capacity to adapt models to the new norm; 4/ a critical approach to solutions and “good practices” in an international comparison of the production of peri-urban space and the control of buildable land

Participants invited to submit a paper in this session will come from universities specialized in spatial planning, spatial economics and real estate-urbanism in Europe and North America: UQAM and UdeM (CAN), University of Westminster (UK), University of Amsterdam (NL), Haute Ecole Charlemagne and AP Hogeschool Antwerp (BE), Univ. Neuchâtel (CH), Universitat Pompeu Fabra (ES), ESAI Lisbon (PT), Manhattan Institute of Management (US), but the call will be open to any other institution interested in the topic. The selection of the contributions will be double-blind.

The session, bilingual French/English, will benefit from a simultaneous translation financed by the organizers. It will be organized in person on two slots (2 x 1h45) and will include 10 interventions, at a rate of 15 minutes per contribution plus a common debate for each theme (also 15 min).
