Conciliating urban development and social diversity in times of housing crisis: what are the solutions ?


Wednesday 6 Dec 2023
From 4PM To 6PM

In a context of changing lifestyles, climate change and housing crisis, public authorities are getting involved in various projects to adapt the built environment of major cities and increase the housing supply (greening, public transport, new districts among others). While these projects attempt to meet objectives that appear legitimate in the eyes of many, they are also often criticized for the gentrification they can lead to. Indeed, the improvement of the built environment and the development of new neighborhoods often seem to offer housing options that primarily benefit the most affluent households.

How can we invest in adaptation to climate change and increase the housing supply in major cities, while preserving social diversity ? 

This event brought together representatives from research, public authoritiescommunity, private sector and the public to discuss ways of reconciling urban development and social diversity.

  • Isabelle Melançon (Institut de développement urbain du Québec)
  • Jean-Philippe Meloche (UdeM et CIRANO)
