Pastoralism is a form of livestock farming based on continuous or seasonal, local or regional herd mobility. This livestock rearing strategy is geared towards meeting the herd’s nutritional needs via intermittent grazing of fodder resources of often spatiotemporally varying availability and quality. In Sahelian-Saharan areas, pastoral livestock farming is family-based, devoted to cattle breeding and production, and secondarily to milk production. This major economic activity accounts for an average 38% of the agricultural GDP of the concerned countries2, while providing employment for livestock farmers, as well as for all stakeholders in the value chain right up to urban and coastal consumers. Moreover, it is a way of managing ecosystems and safeguarding the social structure and culture.
