Throughout history, governments have used customs and laws to organize and codify access to land in different forms. Often, land reforms amended these laws by rearranging land access through property titles. How did land reforms affect land access and ownership rights in different contexts? Did they contribute to the commodification and financialization of land by making “property” of it? What processes and actors were involved? How have these affected land use change, such as in agriculture or urban development? This panel will provide valuable insights into the complex interplay between land reform, property rights, and institutional changes in diverse regions and times: Italy and India in the 19th century, and China in the 20th century.

Speakers : 

Michela Barbot is Permanent Researcher at the CNRS Research Unit IDHE.S and Adjunct Professor of History and Social Sciences at the Ecole normale supérieure Paris-Saclay. Since 2020, she has also been teaching urban history at the Urban School of Sciences Po. At the intersection of economic and legal history, her researches focus on the historical evolution of property rights, valuation procedures and real estate markets in Italy and continental Europe (16th-20th centuries). On these topics, she has published the books Property Rights and their Violations. Expropriation, Seizure and Confiscation in Europe and its Settlements, 16th-20th centuries (Peter Lang, 2012, edited with L. Lorenzetti and L. Mocarelli), and Les règles de la valeur. Une histoire juridique de l’évaluation économique (Presses de l’Université Toulouse Capitole, forthcoming). 

Sukriti Issar is Associate Professor in CRIS (Center for Research on Social Inequalities) at Sciences Po, Paris. She is the scientific advisor of the Governing the Large Metropolis master’s program at the Urban School of Sciences Po, Paris. Her research interests focus on urban policy, regulations, property and law, and social history.

Thomas Vendryes is Assistant Professor of Economics at University/ENS Paris Saclay, Centre for Economics at Paris-Saclay (CEPS). Specialized in the field of Development Economics, he is in particular interested in the two-way relationship between institutions and development. One of his main topics of research has been the evolution of land rights and related institutions in rural China since the onset of the « reform and opening » era in 1978, questioning how this evolution has shaped the Chinese experience of development, and how it has been shaped by local political economy mechanisms.


Coffee break


Various forms of land regulation have historically made and unmade urban settlements informal, irregular, or non-compliant as they impose certain rules on land use, development, and construction. Examples abound, from housing considered “unsanitary” in late 19th century London to “irregular” land subdivisions in mid-20th century São Paulo and contemporary “energy-intensive” housing in Paris. This roundtable aims to bring together research tracing changes in urban land regulations and explain their production and/or effects in urban societies across the Global North and South and different historical periods. Which types of regulations (sanitary, land use, land development, construction, environmental, etc.) produce (in)formalities? How do multiple urban land regulations interact or conflict? What effects do they produce in spatial and social dynamics?

Her expertise encompasses land, housing, property markets, public action, and urban planning practices. She has conducted research in several countries, including Lebanon (1997-2001), Cambodia (2001-2005), and Syria (as responsible for the Urban Observatory of the Middle East at the French Institute of the Near East, Ifpo, 2007-2011).
