The ‘Tool for Agroecology Performance Evaluation’ TAPE has been developed by the FAO to assess the impact of agroecology with a globally applicable and comparable method (based on a 2-3hours farm interview. The environmental dimension has so far been represented by a soil index (visual analysis) and an agrobiodiversity index which is based on the crops grown and animals kept While the TAPE biodiversity index is crucial, it does not take into account “unplanned biodiversity" (i e farm management practices). This poster for the EGU general assembly 2024 introduces the new developed biodiversity index for TAPE.
