    Facing problems of land, natural resources and environment, Sahelian governments have become increasingly aware that solutions must be sought first among local communities. These communities, in association with government at local and national levels, should be responsible for land and natural resource management. This chapter discusses recent land tenure and environmental management developments as they have occurred in Mali.

    Time series of vegetation indices (VI) derived from satellite imagery provide a consistent monitoring system for terrestrial plant productivity. They enable detection and quantification of gradual changes within the time frame covered, which are of crucial importance in global change studies, for example. However, VI time series typically contain a strong seasonal signal which complicates change detection. Commonly, trends are quantified using linear regression methods, while the effect of serial autocorrelation is remediated by temporal aggregation over bins having a fixed width.

    In contrast to their sedentary image, farmers in Central and South Mali are surprisingly mobile. Many have settled in scattered farming hamlets where they are rapidly expanding the areas under agriculture. This study focuses on farmers’ mobility in relation to accessing land in two regions in Mali where farming conditions are very different regarding rainfall, population growth and opportunities for income generation. It is shown that differences in farming conditions in the two regions have shaped the different temporal and spatial dimensions of farmers’ mobility.
