By addressing the following important biodiversity gaps:

1. Filling data gaps in the geographic, temporal, habitat and taxonomic composition coverage from in situ biodiversity observations;
2. Filling knowledge gaps, thereby assessing global species diversity;
3. Forecasting ecological degradation in order to define effective actions to reduce terrestrial biodiversity loss; as well as
4. Filling gaps in the data-policy link may lead to a disconnection of biodiversity data that EO can generate and policy strategies including the EU Biodiversity Strategy for 2030, the UN SDGs and the Convention on Biodiversity (CBD) post-2020 targets.
