HUMUS sapiens represents a compilation of soil explorations emerging from the networks of mikroBIOMIK, Hackteria, and Gasthaus – with the ambition to bring DIY (do-it-yourself) and DIWO(do-it-with-others) approaches as well as an open-source-based “hacker spirit” into soil ecology. Participants are invited to reflect on current scientific discourses and critical societal challenges through hands-on tinkering and curiosity-driven research.
