On Thursday, the Seventeenth Plenary Session of the Group on Earth Observations (GEO-17) focused on the use of Earth observations data to bridge the digital divide. GEO members presented examples of projects and initiatives underway around the world to enable full and open access to Earth observation data, and promote policy development and informed decision making.

Carolina Adler, Executive Director, Mountain Research Initiative, and James Thornton, Mountain Research Initiative, highlighted the GEO Mountains initiative. They gave examples of outputs, such as the Inventory of In Situ Observational Infrastructure, which is an online inventory and web-mapping application. Krishnachandran Balakrishnan, Indian Institute for Human Settlements, discussed the India Data Cube, project which aims to generate land cover, population, and development indicator maps at sufficient spatial and temporal resolution to meet the needs of policymakers.

The session on “Nature-based Solutions (NbS)” put a spotlight on GEO’s work on NbS to address societal challenges and mitigate ongoing environmental crises. Elizabeth Maruma Mrema, Convention on Biological Diversity (CBD) Executive Secretary, emphasized the need to apply Earth observations to inform NbS and help tackle the interconnected crises of climate change and biodiversity loss. She highlighted opportunities for the GEO community to contribute to the discussions on the post-2020 global biodiversity framework, as providers of high-quality geospatial data required to monitor the framework’s targets and goals.

The GEO Week 2021 Youth Track also continued, and featured a cross-regional dialogue between Europe, the Commonwealth of Independent States and Asia-Oceania. In a keynote address, Yan Liu, Chinese Academy of Sciences, shared her experience as a young scholar working with GEO. She said working with experienced China GEO researchers enabled her to refocus her own research questions.

The side event on “Pathways to Impact in Africa” highlighted the vital role of open, operational platforms for Earth observations data and showcased the Digital Earth Africa and Africa GeoPortal platforms. Adam Lewis, Digital Earth Africa, described the platform as one that uses Earth observations to provide analysis-ready data to support policy and investment decisions. He explained it provides access to free and open data sets, and open-source tools that can be used by all to support achievement of the Sustainable Development Goals and other global policy agendas.
