Diachronic analysis of vegetation in the Sylvopastoral zone (Senegal):what lesson to learn from?

摘要：

The Sylvopastoral zone(ZSP) of Senegal has been occupied for several centuries by pastoralists.During this period,frequent bush fires traversed the zone.During the 1950s the installation of boreholes allowed a permanent settlement of an increasing livestock population.Since 1970, the modifications due to these factors were reinforced with rainfall deficits in particular.To better understand this phenomenon, monitoring was initiated, but discontinued.However, the changes related to these factors continued.The objective of this study was to identify the recent dynamics of the vegetation.
