Nowadays, tropical zones are characterized by a catastrophic decline of forest ecosystems areas which play however an important role in climate regulation and biodiversity conservation. There are numerous and complex causes of deforestation. Even if agriculture is one of the main causes of deforestation in most tropical regions, sub-Saharan Africa had exceptional influences related to social conflicts. In Burundi, socio-political instability which occurred in 1993 also led to massive waves of displaced people, essentially farmers. The present study aims to analyze the land cover spatiotemporal dynamics and focuses particularly on the influence of this population forced to migrate. The study combines satellite images analysis with field observations to analyze land cover dynamic in the camp's surrounding zone. The negative impact of the socio-political instability has been demonstrated by vegetation anthropization decrease when the distance from the camps increases. The greatest anthropogenic pressure which is observed during the period that followed the outbreak of the socio-political instability also confirms this negative impact. The rehabilitation of those deforested or degraded zones is therefore essential. © 2018 Agri-Overseas. [less ▲]

The studied forest is a protected area located in Southern Burundi, close to Bururi city and to agricultural villages. The effective protection of this forest started in 1980 but the protected area delimitation occurred in 2000. The forest spatial dynamic is analyzed to assess the effectiveness of this protection status. The study combines six Landsat multispectral satellite images analysis with field observations. Forest area and perimeter analysis highlights its dynamic in two phases: the first one is mainly characterised by deforestation and savannah development around agricultural lands but also by forest regrowth processes between 1986 and 2001. The second phase (2001-2011) of the forest dynamic is characterized by the increase of its surface and perimeter following the transformation of savannah zones. The anthropogenic effect limitation linked to the protected area delimitation, agricultural activities disturbance during socio-political instability period and to the increasing number of forest-rangers, would have influenced the surface and perimeter gain between 2001 and 2011. Local population implication in forest protection could further limit human pressure and promote degraded zones regeneration. Thus, agropastoral practices innovation in neighboring villages of the protected zone could contribute to limit these anthropogenic disturbances. [less ▲]
