Abstract

Abstract The Algerian steppes frequently experience droughts and significant anthropogenic activities than harm its natural resources, endangering the fragile arid ecosystem’s balance. Hence, an analysis of steppe degradation can be instrumental in initiating remedial measures in the region. This study aims to assess the level of rangeland degradation in the southern Hodna region, a crucial component of the steppe landscape, and analyse the factors driving this degradation. The methodology employed a supervised classification technique, using multi-temporal remote sensing imagery from 1987 to 2016 to analyse land cover distribution. Furthermore, land cover dynamics were combined with carefully selected climatic and anthropogenic data, which were then subjected to canonical correspondece analysis to identify the primary drivers of rangeland degradation. The results reveal a sustained change in land cover dynamics, with a no table 48.65 % reduction in the rangeland class. Simultaneously, there has been a continuous expansion in sand dunes, rangeland degradation, and agriculture classes. It is worth noting that canonical correspondence analysis reveals stronger associations between rangeland degradation and anthropogenic factors than climatic factors. Finally, the study offers crucial insights into rangeland degradation in southern Hodna, aiding policymakers and land managers in developing sustainable development strategies for the region.
