The Global Conference on Biodiversity and Monitoring is organized by GEO BON and partners between 10-13 October 2023 in Montreal. The focus of the event is the challenge of ‘Monitoring Biodiversity for Action’ and the development of best practices and technologies for biodiversity monitoring and observations. The conference allows to share and exchange scientific and traditional knowledge related to biodiversity changes, at many levels: from genes to ecosystems; the associated contributions to people, across all sectors of society; and its conservation, sustainable use and shared benefits.
