This document provides an activity report for the Intergovernmental Technical Panel on Soils (ITPS) from 2018 to 2021. It lists the members of ITPS by region and notes their working groups on topics like soil biodiversity, erosion, and pollution. Key activities included preparing guidelines on soil pollution, organizing a global symposium on soil erosion, and reviewing documents on topics such as soil organic carbon and salinity maps. ITPS also collaborated with organizations like IPCC, IPBES, and CBD on soil-related issues. Future activities include reviewing additional documents and programs and contributing to the second World Soil Resources report in 2025.
