An international research program between a Frenchteam (ThéMA) and an Algerian research team (CRASC-Oran)4 years (2007-2010)

The main objectives : - Identifying, analyzing and evaluating the recent territorial mutations of the South-Western Sahara in Algeria- Proposing a synthesis of those evolutions- Developing the interactions with the local actors- Developing a modeling and instrumented approach to propose some elements able to participate in the territorial management process

10 researchers in Geography, Architecture & Urbanism

Conclusion – future outlines

To increase the quality and quantity of data, and the number of the thematic fields and the spatial scales

To put online the tool to work more cooperatively andeasily with the Algerian team

To develop the other dimensions of the territorial observatory: documentation…

To structure the spatial indicators by thematic in regards ofthe available data and the expectations of the local partners
