Ce texte présente le dossier thématique Centenaire de René Thom (1923-2023): hommage sémiotique et morphodynamique.

Since 1984, the Mexican government has tried to stimulate the economy in a poor and peripheral area of the country. They aimed to do so by developing an Integrally Planed Resort (CIP, in Spanish) in a community, located in the Oaxaca state on the Pacific coast. Being based on the expropriation of some parts of the communal territory, this process created some remittances among the local communities. Today, this resort is still a fragmented space and reflects social inequalities and social conflicts. From a social geographical perspective, this article aims to show the social conflicts and social compromises among the local society. Space appropriation, power battles and strategies developed by the different actors, will be the main tools to investigate this planning model. In this model, the government too often has ignored social realities on the local scale.

Faced with increasingly rapid urban sprawl, developing Asian cities struggle to control their urbanization. While Hanoi, the capital of Vietnam, is also struggling to curb its own rapid urbanization, in the 1990s, the government adopted a new policy to orient and shape urban expansion. This policy is based on the planning and construction of “new urban areas” (khu do thi moi). This article provides a cartographic analysis of the implementation of these areas across the city-province’s territory and examines issues related to their territorial expansion.
