From 22 to 26 November, the Group on Earth Observations (GEO) organizes the GEOWeek2021. This event convenes scientists, researchers, UN representatives, policymakers, and academics to discuss how earth observation, notably through the lens of nexus thinking, addresses climate change, biodiversity, the ocean, and ecosystem restoration. Most of the GEOWeek2021 will run on the following Airmeet event platform.
