International audience. Small ruminant farming is the main rural occupation in mountain areas of Morocco. This activity is subject to numerous pressures, including repeated climatic hazards that modify pastoral resource availability and trigger changes in production systems. This study aimed to identify and analyse changes in availability and utilisation of pastoral resources acknowledged by farmers over the past 40 years for the small ruminant farming systems of the Central High Atlas region of Morocco. We hypothesised, on the basis of previous research, that resilience of the pastoral component of such systems increases with elevation. We interviewed 50 farmers in three municipalities of Azilal province, at moderate (800-1400 m), medium (1400-1800 m) and high (1800-3000 m) elevations. In the 1970-1980s, pastoral resources were abundant and mobile flocks grazed collective rangelands. Subsequently, repeated droughts and the increased stock numbers promoted by agricultural policies led to the deterioration of resource abundance and quality, especially palatable plants. At moderate elevations, wooded areas and phytomass declined; erosion occurred at high elevations. Traditional systems diversified by including agricultural activities. At moderate elevations, livestock farming intensified, with the adoption of a productive breed, concentrate distribution and the grazing of fallow land. Currently, flock mobility is limited and rangelands provide less than 60% of sheep requirements. At high elevations, the pastoral component persisted at the cost of a diversification of pastoral areas and greater flock mobility. Rangelands are still collectively managed and provide almost 90% of sheep requirements. Since rangelands remain a major feed source, changes in pastoral resources can be considered as a major driver of change in livestock systems. The sustainability of small ruminant farming systems at these elevations thus depends on the conservation of rangeland.
