    Tetra Tech’s land tenure and property rights experts examine how weak land and resource governance can fuel drivers of violent extremism. With a focus on the African Sahel, this new issue brief finds this dynamic is especially prevalent when land and resource governance challenges are coupled with environmental disruptions, resource scarcity, or migration.

    For 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

    Land use change has become increasingly acknowledged as an important issue in terms of understanding the processes of global change. Hence, land use decision-making by smallholder communities in developing countries become a vital part of the broader comprehension of environmental and social change that are related to the change processes at the global scale. A wide range of analytical and conceptual frameworks has been developed to facilitate and sharpen such analyses, ranging from very theoretical to directly operational approaches.

    Trees in the Agrarian Systems of the Sahelian Zone of Niger: Management Practices, Benefits and Constraints. In the Sahelian regions, tree is an integrated part of the farming systems. The present study concerns the tree management practices, their benefits and constraints. A survey was conducted in 7 village sites of the southwestern part of Niger according to a southnorth aridity gradient in order to understand how rural people manage trees in their farms. The objective was to analyse the systems, tree management practices, benefits and constraints.
