“…The contribution of these land uses to the enhancement of human well-being was assessed by estimating economic benefits (employment supply, monetary incomes) and the provision of five categories of ecosystem services (MEA, 2005): supporting (soil fertility, primary production), regulating (erosion control, flood control, local climatic regulation), provisioning (biomass production, forage productivity, food supply, aromatic and medicinal plants, water retention), cultural (aesthetic value, traditional value) and biodiversity (species richness, plant endemism, game abundance). This set of 17 services was selected on the basis of data availability, expert advice and our own experience in Béni Boufrah and similar semiarid areas (Derak and Cortina, 2014). Furthermore, we asked six experts in hydrology, forestry and sociology, as well as representatives of governmental offices and environmental organizations.…”
