Les AA. analysent l’impact du secteur équestre sur le développement des utilisations du sol multifonctionnelles en zones péri-urbaines suédoises. (Skåne, Halland, Gåvle, Stockholm). Ils étudient ces différentes caractéristiques du point de vue de la
planification régionale, économique et du développement durable. Ils expliquent qu’il est nécessaire de comprendre comment les différentes parties prenantes peuvent-elles coopérer pour dynamiser le développement rural et péri-urbain. Ils concluent que la
