In spite of its large area (2.4 million km), Algeria has only 8 million ha of UAA, of which only 443 000 ha are irrigated (0.05%). With a population of more than 30 million inhabitants, the country registers 0.25 ha per capita, which represents a very low ratio. Agriculture is concentrated in a narrow fringe concentrated in the North, where the dominant climate is semi-arid with very irregular rainfalls. In the South, a steppe area of more than 30 million ha is mainly devoted to small ruminants' production. A majority of farms produces its main part of income from cereal crops–livestock association system. However, the diversity of the climate and the physical environment, on one hand, and the agricultural policies on the other hand, induce major transformations in these systems. Transformations are also the result of a significant demographic growth in rural area. This fact is translated by an increase in food needs. In this context, significant issues appear in term of resource’s uses and systems’ sustainability. To shed light in the actual situation, this study, based on a survey of 90 owners, shows that: the intensification can constitute a threat on the pastoral resources; the weakness of the farms encourages the generalization of practices characterised by a weak feed autonomy and a bad management of stock fodders; the animal interspecific integration and partial intensification are positive if they follow models which ensure autonomy, performance and optimal pastoral resource management. Résumé Malgré sa grande superficie (2,4 millions de km), l’Algérie ne possède que 8 millions d'ha de SAU, desquels 443 000 ha seulement sont irrigués (0,05%). Avec une population de plus de 30 millions, le pays dispose de 0,25 ha per capita, soit un très faible ratio. L'agriculture est concentrée dans une frange étroite du nord où dominent un climat semi-aride et des précipitations très irrégulières. Dans le sud, une aire de steppe de plus de 30 millions d'ha est consacrée principalement à la production de petits ruminants. Une grande partie des fermes tire une majeure partie de leurs revenus du système céréale –élevage. Le climat et l'environnement physique, d'une part, et les politiques agraires d'autre part, induisent des transformations majeures de ces systèmes. Les transformations sont également le résultat d'une augmentation significative de population de secteur rural qui a conduit à une augmentation des besoins alimentaires. Dans ce contexte, des enjeux fondamentaux apparaissent sur l'utilisation des ressources et la durabilité des systèmes. Pour mieux éclairer cette situation, cette étude, basée sur une enquête de 90 agriculteurs, montre que (i) l'intensification peut constituer une menace sur les ressources pastorales (ii) la fragilité des fermes encourage la généralisation des pratiques marquant une faible autonomie de l’élevage et une mauvaise gestion des stock fourragers (iii) l'intégration interspécifique animale et l'intensification partielle sont positives si elles suivent les modèles qui assurent l'autonomie, le revenu et la gestion optimale des ressources pastorales. Introduction Only a narrow fringe situated in the North of Algeria is not a desert area. It is about 1200 Km long from east to west and 200 to 350 Km large and is inhabited by more than 24 million people, which represents 70% of the total population. This part has a highly undulated relief, few plains and diversified, provides good conditions to erosion. In this context, agricultural activities, mainly rainfall-related, have to take into account the preservation of the environment. It is worthy to note that for these reasons, agriculture in Algeria is farmer/ cattle breeder and nomads’ ones. Furthermore, development of agriculture has always faced physic and climatic constraints.
