Articles et Livresdécembre, 2010Afrique, Afrique septentrionaleThe countries in North Africa share an arid and semi-arid environment with high diversity: mountainous areas run alongside maritime areas and desert. Currently, urban dwellers in North Africa represent more than 50% of the population and are expected to be more than 60% by 2030. However, the urban system in North Africa is suffering urban primacy. The region is well known for its endowment in mineral deposits such as oil and gas. However, it is also known for being one of the poorest regions in the world in water resources.

Articles et Livresdécembre, 2010Algérie, Burkina Faso, Nigéria, Mauritanie, Mali, Sénégal, Éthiopie, Niger, Uruguay, Érythrée, Cameroun, Tchad, République centrafricaine, Soudan du Sud, Soudan, Brésil, Afrique, Amérique du SudFor over a decade, the globalisation of environmental, economic and social issues has induced rapid modification in agriculture and land. These changes raise the question of future extensive livestock systems in regards to the worldwide challenge to double livestock production by 2050 in ways which are safe for the environment. In order to better understand and follow modification processes, a comparative study of livestock systems and land dynamics has been carried out on seven case studies on three continents through the use of a common grid.

We propose a flexible and adaptable framework to assist the quick design of models dealing with the durability of the extensive livestock systems at the territorial scale. This metamodel results from the collaborative design starting from MAS developed on 7 sites in Latin America, France and Senegal. It is composed of four packages: Agent, Community, Space and Vegetation-Herd. We illustrate these packages with examples extracted from the various models. The role of this tool is discussed in order to show its advantages and its limits
