Strategic evaluation of the sustainability of the Spanish primary sector within the framework of the circular economy

Abstract Food security depends on the implementation of sustainable development in agri‐food. It is essential to determine the sustainability of the main production systems in order to establish specific measures for each territory, by virtue of correcting their negative externalities and improving the commitment of stakeholders. Therefore, this article assessed the economic, social, environmental and global sustainability of the Spanish primary sector based on a synthetic indicator proposed in previous research. The results suggest the existence of a moderate degree of sustainability of the food production system in Spain (0.5019), with the regions of Aragón (0.5482), Castile and Leon (0.5473), Extremadura (0.5438) and Andalucía (0.5399) standing out. An inverse relationship between the economic and the environmental subcomponents of sustainability was obtained. The cluster analysis revealed the need to apply a customized territorial policy in order to meet sustainability goals due to the diversity of agricultural subsectors identified in them.
