The first BES-Net Trialogue was held in Sarajevo in October 2017 to reach a common agenda for action around pollinators in Eastern Europe as the driver to foster links between ecosystem services, agriculture and rural development in the region. The Biodiversity and Ecosystem Services Network’s (BES-Net) Trialogue provides a constructive space for the three communities of policymakers, scientists and practitioners to learn together and fostering inter-cultural understanding and interinstitutional coordination around biodiversity/ecosystem issues of common concern.
