Group on Earth Observations Land Degradation Neutrality (GEO LDN) Initiative
The GEO Land Degradation Neutrality Initiative (GEO LDN) is a stakeholder-driven initiative that was launched in 2018 during the Group on Earth Observations Week in Kyoto, Japan. It brings together Earth observation data providers and governments to develop minimum data quality standards, analytical tools and capacity building needed to strengthen land degradation monitoring and reporting, using remote sensing and data collected on site. Through this work, governments will have the necessary data and tools to prioritize interventions and monitor outcomes to manage land better.
The GEO LDN Initiative responds to a call made by the UNCCD’s Conference of the Parties (COP13) to bring data providers and data users together and support global efforts to avoid, reduce and reverse land degradation globally.
The Vision of GEO LDN believes in the power of geodata for sustainable land management. Harnessing open data for monitoring land degradation is instrumental for reporting but also to support planning and decision making processes for sustainable land management at sub-national levels.
GEO LDN involves all relevant stakeholders (data providers and data users) and welcomes active engagement from new stakeholders in an inclusive and open process. Members are encouraged to take part in three (3) GEO LDN Working Groups:
- WG1 Capacity Building
- WG2 Data Quality Standards
- WG3 Data Analytics
“Land degradation is an existential crisis. Until now, monitoring it in real time felt like an insurmountable challenge. No longer. With Earth observation datasets and the practical tools to use them readily available, decision-makers and land users will have immediate and actionable information to scale up sustainable land management and planning. It is a first step to boosting our resilience,” said Monique Barbut, Executive Secretary, United Nations Convention to Combat Desertification here.

Working Group 1: Capacity Building
The aim of the WG1 is to develop an innovative capacity building mechanism that provides answers to SDG 15.3 while addressing the needs of various stakeholders at regional, national and individual levels. Strengthening capacities will take place at individual, organisational and institutional level, ensuring an enabling environment to achieve the GEO-LDN goals.
The outputs of WG 2 and 3, together with other reporting requirements and/or decision-making supporting tools, will be the input for the development of the CB interventions. Rather than developing the content of the CB interventions, WG 1 will explore and promote mechanisms to support, effectively and innovatively, the strengthening of the required capacities on the three intervention levels.
Working Group Leads: Amos Kabo-bah (UENR), Joost Teuben (ITC/GEO), Timothy Dube, Mercy Ojoyi, Patrice Sanou
Working Group 2: Data Quality Standards
The main task of WG2 is to develop “minimum” data quality standards and decision trees for the underlying data used for estimating changes in the sub-indicators (land cover, land productivity and soil organic carbon) and calculating SDG indicator 15.3.1 (proportion of land that is degraded over total land area).
The objective is to ensure consistency, coherence and comparability of data sets supplied by various data providers in support of country efforts to monitor SDG 15.3.1 and its sub-indicators. The intent is to achieve this through the development of “minimum” data quality standards, taking into account the needs of decision makers, data producers and data managers.
Working Group Leads: Antje Hecheltjen (GIZ), Sara Minelli (UNCCD)
The WG2 data provider and user workshops resulted in a technical document and decision trees on data quality standards:
- Minimum data quality standards and decision trees for SDG Indicator 15.3.1: Proportion of land that is degraded over total land area. Technical note
These are handed over to WG3 as well as to the team updating the UNCCD Good Practice Guidance on SDG indicator 15.3.1.
This work was financed by the German Federal Ministry of Economic Cooperation and Development (BMZ).
Extract from the data quality standards decision trees. These trees will help global and national to sub-national data providers evaluate whether their data on land cover, land productivity or soil organic carbon adhere to the minimum data quality standards.

Working Group 3: Data Analytics
Working Group 3 will work towards establishing a federated collaborative data analytics platform (FCDAP) to assist countries to calculate SDG Indicator 15.3.1 and assess their progress towards Land Degradation Neutrality (LDN). WG3 will support the development and implementation of big data analytics tools, consistent with the relevant standards identified in GEO LDN WG2 (Data quality standards), to enable countries to easily access, analyze and interpret large Earth observation (EO) datasets in globally consistent ways while also facilitating national data sovereignty.
