The objective of this research is to follow the evolution and sustainability of the natural resource management systems adopted by different breeders found in the Al Bayadh region in Algeria. Using a stratified sampling method, 52 farms were surveyed between 2010 and 2015 to capture the diversity of farming systems and identify changes in land use patterns. The findings of the research reveal a predominance of sedentary and semi-transhumant farming systems with a sharp decline in nomadism. This study enabled us to identify three types of breeding: sedentary breeding systems with short-term fattening (type 1), semi-sedentary systems with medium-term fattening (type 2), and transhumant/nomadic systems with long-term fattening (type 3) that therefore reflect a diversity of actions in the management of the risk that threaten livestock production.

Economic, social and political transformations have a manifest effect on the relationships that the various actors have with steppe resources. Highlighting the multiplicity of actors explains the development of conflicts over the use of this resource. The present work aims, on the one hand, to shed light on the problem of conflicts in the Brezina area, in particular the identification of conflicts and the analysis of the various socio-economic issues of these conflicts. And on the other hand, to study the different mechanisms contributing to the management and neutralization of these conflicts, and consequently, to ensuring sustainable local development of this territory. The results of joint classification obtained in our groups of surveys presenting similar declarations to carry out classes of authorized variables. The suitability of the variables in these measurement classes seems to reveal the same capabilities of representations. In the most important variances attains 100%. that of these key variables, to maintain good relations with local authorities (Mbr1), and the impact of the presence of nomads in the territories (Pnt), and more than 90% for an essential role of controlling farmers and breeders (Rec), They are effective in conflict management (Egc), these aspects reveal the strategy of these breeders in the management of resources in the territory. The index of the alpha value of the determined cronbach, shows satisfactory results around 0.887%.It should be noted that conflict resolution is closely linked to cultural specificities, community structures and the mode of communication between users. This resolution currently remains difficult and ambiguous because of the presence of several actors ; users of steppe areas, and of a multi-institutional system.

The cattlemen of the steppe are faced with climate risks whose consequences are at the origin of one of the essential mechanisms of the degradation of resources natural fodder, thus making uncertain the food of livestock. Thus, faces to the changing socio-economic and climatic risks, the pastoral society has implemented different adaptive strategies to ensure the reproduction of its operating systems. The objective of this study is to analyze the patterns of the use of the space of the pastoral area called El-Bayadh in order to show how the actors adopt and adapt the techniques of production available in order to ensure the security of the production of their exploitation in an environment particularly fragile, hostile and vulnerable. It is therefore to take knowledge of the basic strategies implementation and the responses provided by the livestock producers to protect themselves against the consequences of a difficult climate in order to ensure the conduct of the food needs of their animals and the reproduction of their operating system.
