PSDR4 Sebioref - Une approche paysagère et territorialisée des services écosystémiques et des valeurs attachées pour guider les décideurs publics

Abstract : The aims of the Sebioref projet was to estimate the pollination service provided by wild bees and identify the landscape properties driving the delivery of this ecosystem service. The ultimate objective was to explore the potential coordination between ecosystem service providers and users at the landscape scale. The project was conducted by three laboratories (Dynafor, Cesbio, Lereps) and co-led by the Chambre Régionale d’Agriculture d’Occitanie. The Sebioref project has provided remote sensing tools to identify floral resources in grasslands over large spatial extents and spatially explicit modelling of both pollination service and stakeholders’ cooperation. We show that the management of pollination services for insect- dependent crops needs a landscape-scale approach, in order for the crop-pollinating bees to benefit from complementary floral resources provided by hedges, wood edges and grasslands. The agro-ecological transition should therefore take into account landscape-scale ecological processes to maximize pollination services. We have also showed that stakeholders feel very concerned by wild bee conservation and could generate insightful suggestions to promote wild bee diversity and pollination services. Collective action seems to be the best way to meet expectations for multifunctional landscape.
