This approach, traditional in nature and supported by the National Mechanism for the Prevention and Management of Disasters and Food Crises (DNPGCCA), consists of a Geographical Information System, which integrates the water resources, the movement of populations, and the spatial distribution of grazing land, also in terms of the quantities of forage resources. The objective of the approach is to provide a tool to support the management of pastoralism and the identification, tracking and prevention of potential food crises.
