The United Nations has proclaimed 2021-2030 as the decade of ecological restoration. In terrestrial ecosystems, ecological restoration starts with restoring soils, soil biodiversity, and soil functioning. The purpose of this webinar is to explore recent advances in research on how soil biodiversity contributes to ecological restoration in a variety of ecosystems, from agricultural to (semi)natural. In the webinar, besides considering some recent advances in this topic, we will focus on new understanding and theories on the restoration of soils and how it is influenced by soil biodiversity. Join Moderator Katharine Suding (Univ Colorado, USA) and panelists Sara Baer (Univ. Kansas, USA), Raul Ochoa Hueso (Univ. Cadiz, Spain), Susana Rodríguez Echeverría (Univ. Coimbra Portugal), and Jasper Wubs (ETH, Zurich) as they discuss their research, major gaps, and how soil biodiversity research contributes to ecological restoration.
