6. Conclusion
The planet needs sustainably managed forests to control soil erosion and promote soil conservation. Tree roots stabilize the slopes of ridges, hills and mountains and provide the ground with the mechanical structural support necessary to prevent shallow movements of the land mass: landslides occur only very rarely in areas with heavy cover forest. The forests of the region of Sidi Bel’Abbes are part of Mediterranean forests characterized by floristic heterogeneity. The floristic diversity depends mainly on climatic, edaphic and anthropogenic factors. The mapping of changes in forest and soils of Tenira revealed, after the treatment of data sensor of the summer season between 1987 and 2018, various modifications of this forest cover plant and constitutes a typical model for the evolution of Algerian forests. It appears that different classes of forest species and soils have recorded cases of progression and regression during this period. The forest and agricultural areas are under constant pressure imposed by the climatic conditions; types of land used and repeated fires. The socio-economic parameters are also key factors in the use of soils in forest areas and act on their dynamics. This contribution with these preliminary results will encourage the interested community to think about fire danger assessment; identify fires from forest fires, air quality to monitor and map fire in real time (perimeter, area, propagation rate, intensity); the creation of satellite platforms for monitoring and mapping fire, to encourage the use of drones in fire management. The estimation of carbon emissions strengthen national and international collaboration in the field of remote sensing related to forest fires and place the critical role of this technologies in reducing the costs. Therefore it is necessary to sensitize the population that the restoration of forests in arid zones is vital for soil protection.
