SDG 15.3.1 GPG Addendum

The SDG 15.3.1 Goop Practice Guidance Addendum offers clarifications and updated methodological guidance to improve national estimations and the tracking of land degradation over time. Building on the UNCCD's Good Practice Guidance, this addendum introduces key updates such as enhanced methodologies for period assessment, new guidance on selecting representative datasets, and a mechanism to operationalize counterbalancing for achieving Land Degradation Neutrality. It also ensures consistency with widely-used software like Trends.Earth, providing countries with the tools to monitor and report progress effectively.
