Climatic change, overconsumption of resources, city congestion, pollution, urban insecurity, etc. The planet’s ever-increasing urbanization is posing major challenges to our societies.
At the same time, the city remains an irreplaceable center of civilization. Its strengths such as human density and diversity, cultural and economic vitality, its formative role for the rest of the country, etc., all explain the rise of urban living. By taking up those challenges and making the most of those strengths, we will build sustainable cities. There is no unique model for doing so. Over and above cultural and territorial diversity, city-dwellers throughout the world have, all the same, common concerns and needs.
