The state of plant biodiversity in the high plains of Oran (case of the Wilaya of Saida)

Abstract

The wilaya of Saida is experiencing an alarming degradation of ecosystems resulting in the degradation of plant cover, alteration of soil quality and erosion of plant biodiversity. This alarming situation has its origins in various problems such as: human actions, climate change and the lack of an environmental policy. Our study was conducted on the development of a methodology for multidisciplinary mapping combine's phytoecological between diagnosis and application of remote sensing and Geographic Information Systems G.I.S For an inventory and characterization of the actual state of the plant biodiversity of the region. The exploitation of satellite data from the Landsat satellites, combined with field studies through systematic sampling, allowed us to map vegetation and a map of plant communities.

Arid Rangeland Degradation and Its Driving Forces in Southern Hodna, Algeria

“…Various factors have been identified by numerous researchers to explain rangeland degradation in different regions of the Algerian steppe (Bedrani, 1999;Nedjraoui et Bedrani, 2008;Slimani et al, 2010;Hirche et al, 2011;Arabi et al, 2015;Martínez-Valderrama et al, 2018). These studies highlight the interactive relationship between climate change and anthropogenic activities as the main drivers of rangeland degradation in this region.…”
