abstract = {This Good Practice Guidance (GPG) document provides guidance on how to calculate the extent of land degradation for reporting on United Nations (UN) Sustainable Development Goal (SDG) Indicator 15.3.1: the proportion of land that is degraded over total land area. This guidance supports implementation of the Tier I methods for Indicator 15.3.1 adopted by the UN Statistical Commission, and the
development of analytical methods for measuring its three sub-indicators, which are:
1. Trends in land cover
2. Trends in land productivity
3. Trends in carbon stocks (above and below ground), which is currently represented by soil organic carbon (SOC) stocks.
The Indicator is calculated by integrating the subindicators using a one-out-all-out (1OAO) method, in which a significant reduction or negative change in any one of the three sub-indicators is considered to comprise land degradation. Significant reductions can be identified using statistical criteria, or by a qualitative assessment of the magnitude of change. The Indicator is reported as a binary quantification (i.e., degraded/not degraded) of the extent of degraded land in hectares, and expressed as the proportion (percentage) of land that is degraded over total land area. Version 2 of the GPG incorporates a number of advances in the quality and availability of datasets, as well as analytical methods for calculating Indicator 15.3.1 and its sub-indicators that have emerged since publication of Version 1 of the GPG (Sims et al. 2017). These advances have been identified through research, stakeholder engagement, including analysis of recommendations from countries reporting on Indicator 15.3.1 in the first reporting period in 2018, and reviews of drafts of this report by global experts in relevant fields. This report also incorporates new developments from the growing number of publications and initiatives focused on improving the quality and availability of data and analytics for the SDGs in general, and Indicator 15.3.1 and Land Degradation Neutrality (LDN) in particular. While the measurements of Indicator 15.3.1 form only one part of the assessment of LDN, the relationship between the Indicator and LDN is discussed in more detail in Version 2 (this document), and additional guidance on the calculation and use of measurements during the baseline period should clarify the interpretation of Indicator 15.3.1 for monitoring LDN. The guidance covers three sub-indicators. The Land Cover sub-indicator reports degradation in land cover change based on a national assessment of the positive or negative aspects of transitions from one land cover type to another. In Version 2, this chapter highlights the need for countries to first consider the main drivers of land cover change, and then to determine which transitions to identify as degraded for reporting on Indicator 15.3.1. This chapter incorporates updates to the quality of available land cover datasets and classification methods.},
