Sociological contributions on mobilization and geographic data on housing conditions in France and Israel help social scientists to understand the sense of the “housing crisis”. In the 2000s, both countries have seen a restructuring of the role of the State and the emergence of important social movements denouncing the problems related to housing difficulties. This article compares the factors of emergence of the housing crisis in the two countries, analysing its causes, forms of mobilization, their arguments, social sciences narratives on this question and the technical solutions put forward by governments. Comparison of the two housing crises shows that their sociological meanings reflect different national narratives.

This paper addresses conceptualizations of West African spaces through an analysis of changes in pastoral land tenure systems. West African livestock production has undergone significant changes in the past fifty years. There has been a simultaneous southward migratory drift of Sahelian cattle, a shift to combined farming-herding practices, and increased constraints placed on pastoral herd mobility. The Sudanian and Sudano-Guinean savannas are characteristic examples of these transformations. In these savannas, land that was once devoted to pasture herding is increasingly being devoted to crop production. The result of this encroachment is increased competition for land resources between agriculture and livestock raising. This competition is representative of the wider shift from a “Sahelian” pastoral land tenure system of mobility based on reciprocity to an alternative system that is based on the appropriation of resources. This paper analyzes these dynamics using Henri Lefebvre's theory of the “production of space”. Using Denis Retaillé's interpretation of Lefebvre's “production of space”, I argue that this change in land tenure is brought about through a change in the dominant relations producing space : from a “mobile space” to a territorialization of space. Moreover, understanding linked changes between pastoral land tenure systems and production of space is important for pastoral mobility, the key way that herders maintain their resilience. Territorialization can be a solution for herders to secure resource access in spaces under agricultural pressure (usually Sudanian and Guinean savannas) while efforts to protect common rights must be maintained in areas with lower pressure on resources (Saharian and Sahelian zones).

Video games are today a major cultural practice, present in many parts of society. Nevertheless, we still lack precise studies on the place they occupy in everyday life. A study of the various publics and practices of video games, based upon a questionnaire by phone and semi-structured interviews, shows that the place of video games in the spaces of everyday life varies, according to the commitment of videogame players. Taking here the example of domestic places, this study gives an indication on the importance of this leisure in everyday life of the players and, at the same time, shows the capacity of individuals to produce and appropriate their home. Thus, domestic space appears as a topological, appropriated and negotiated space.

This article examines the important French military contribution to mapping and geographical knowledge of the Iberian Peninsula during the period 1808 to 1823. Firstly, contributions of the Bureau Topographique de l'Espagne (1808-1814), which included different types of documents (such as geographic descriptions, topographical maps and military itineraries), are considered. The analysis will be focused on two main questions : what were the specific objectives of those different types of documents ? What was their fate in the aftermath of the Napoleonic period ? The second part of the article deals with the cartographic work due to the so-called “Hundred Thousand Sons of Saint Louis”, an important but little known episode which was characterized both by efforts to compile military geographic knowledge and by different agreements between French and Spanish armies relating to cartographic cooperation and mutual assistance and exchange.
