Considering urban geo-diversity in global models of climate change mitigation and ecological transition

Denise Pumain (University Paris 1)

There are many attempts at deducing smart urban policies from the global models, which aim at managing an ecological transition in human habitat and activities. Here I would like to recall two major insights, which are brought from urban science and could help to improve the efficiency of such decisions. One is about taking care of the tensions created by persistent or growing inter-urban inequalities or divergences in the distribution of wealth and population at world scale, the other is about enhancing the local geo-diversity (in size, morphology and cultural hybridization of technologies) which is an essential driving force in the complex dynamics of cities within systems of cities. Empirical evidence and simulation models will be presented whose developments could be shared within the TIMES flagship proposal.

Key-words: evolutionary theory of urban systems, concepts and models transfer from self-organizing complex systems towards social sciences.
