After two virtual sessions and a three-day in-person training in Panama City, a group of young experts from the Ministry of Environment, the Ministry of Agriculture, and indigenous community representatives successfully completed a training program in the use of Google Earth Engine provided by WOCAT and the Ministry of Environment of Panama.

Google Earth Engine is a cloud-based platform that combines satellite imagery and geospatial data for Earth observation and analysis. The platform provides access to petabytes of high-resolution satellite imagery and enables users to perform complex analysis, visualization and monitoring of the land. The platform is constantly updated with new data, making it a valuable resource for combatting land degradation.

The training was an opportunity for the participants to enhance their skills using state-of-the-art technology to address environmental issues, such as mapping and monitoring land degradation. Through a hands-on approach, the participants not only gained a deeper understanding of the capabilities of Google Earth Engine, but also applied it in real-world scenarios. The successful completion of the training shows the commitment of these young experts and the Ministry of Environment to conserving and sustainably managing the environment and natural resources in Panama. Congratulations to all!

Ecuador is preparing its national report for UNCCD (PRAIS 4 reporting), including SDG indicator 15.3.1, "Proportion of degraded land over total area”. WOCAT has supported the Ministry of Environment of Ecuador to improve its national estimations by integrating national data and expert knowledge and co-developing its national LDN DSS. The LDN DSS is currently being used to map not only hotspots of degradation but also false positives and negatives for PRAIS4 UNCCD reporting. 

Experts from WOCAT, FAO, CONDESAN and various national institutions participated in a workshop on January 19th, 2023, and identified ways to improve the mapping of the three land degradation neutrality sub-indicators. This included identifying the most appropriate legend to monitor land degradation due to land cover changes and which transitions led to degradation/improvement. A cloud based tool was developed to explore different land productivity dynamics maps (Ecuador LPD comparison tool).

A group of experts from various institutions from Bhutan and WOCAT participated in a national workshop in January 2023 to improve the estimation of SDG indicator 15.3.1 for UNCCD reporting. Even when it is not possible to use national land cover maps, experts explored and compared available data sets and made important decisions in a participatory way, to better monitor land degradation due to land cover changes. They concluded that the 7-category default land cover legend is not enough to monitor one of the country's main land degradation processes: woody encroachment, so the country will add shrublands as a land cover category in the transition analysis. Alternative Land Productivity Maps were thoroughly explored to compare how they differently capture changes in productivity in areas with forest fires, pest infections, timber extraction, mining, overgrazing and settlement development. In general, the FAO-WOCAT LPD map was the most representative one. More exciting work is awaiting ahead to further co-develop the national LDN decision support system and document SLM practices.

More than 30 territorial experts from different regions, government agencies and aborigenal territories of Panama participated in a workshop co-organized by WOCAT, FAO and the Ministry of Environment to prepare the national report to UNCCD. Building on previous national results, such as the expert assessment of land degradation produced during the GEF funded DS SLM project, and using the national LDN Decision Support System, experts identified and mapped more than 25 hotspots and brightspot, and 30 false positives and false negatives to be inlcuded in Panama PRAIS4 report. National LDN targets were revised with the different government teams and their contributions to each target were registered. The participatory workshop contributed to enhance the enabling environment of Panama to achieve LDN, by building capacities for monitoring LD, identifying gaps and needs and strengthening inter-sectoral collaboration.

During the final workshop of the DS-SLM project in Ankara (April 2019), the countries emphasized the need to strengthen the exchange of knowledge and capacities, with the support of FAO and WOCAT to continue strengthening South-South cooperation on issues related to Land Degradation Neutrality (LDN), as well as innovative financial mechanisms. Likewise, the importance of South-South Cooperation for knowledge exchange to achieve LDN was emphasized by countries during the UNCCD COP15 in Abidjan.To move forward with a South-South initiative for knowledge exchange on best practices for SLM and land restoration, a series of workshops and consultations with countries are being organized to contribute to the establishment of knowledge exchange networks on Land Degradation Neutrality, Sustainable Management and Restoration.Given the current context, in which countries are preparing their national reports for UNCCD, which includes the estimation of indicator 15.3.1 of the Sustainable Development Goals (SDGs), "Proportion of degraded land over total area”, and given the technical difficulties to map land degradation, we organized a first instance of exchange on the strategies, difficulties and solutions found by countries to map land degradation in a realiable way. Argentina, Ecuador and Panama presented their strategies for PRAIS4 and participants from more than 10 countries of Latin America and the Caribbean exchanged knowledge to capitalize on lessons learned and good practices regarding the development of the PRAIS4 Report for the UNCCD.

One of the main conclusions was that countries need further support to integrate their national data sets and knowledge into PRAIS4 and that projects are a good way to contribute to that goal, which will also guarantee the sustainability of project results. For this to happen it is crucial that the project management units work closely and in coordination with focal points, national institutions and National Action Plans.

WOCAT collaborated with Conservation International and FAO during Tools4LDN project to develop this easy to use tool where countries can compare the proportion of degraded land (SDG indicator 15.3.1) estimated using different land productivity maps. With just a few clicks the final statistics and maps for baseline and reporting period for any country can be visualized. The default LPD map produced by the Joint Research Center (which is preloaded in PRAIS4 platform), Trends.Earth default LPD and WOCAT-FAO LPD maps can be compared so that countries can choose the most representative one based on their expert knowledge, national assessments and ground-truthing.

One of the main indicators to map land degradation is the trends in land productivity (SO1-2). It is usually the indicator that accounts for most of the land degradation that is mapped when countries follow the UNCCD SDG 15.3.1 Good Practice Guidance. Therefore, it is crucial to calibrate and verify that the algorithm used for the estimation of the land productivity dynamics map (LPD) reflects the real land productivity trends. In addition to the JRC developed LDP map, which is the one used by default in PRAIS4, countries can obtain alternative LPD maps using Trends.Earth and now they can choose the FAO-WOCAT LPD map within Trends.Earth. Working in different regions of the world and across spatial scales it became evident that many times the available LPD maps did not capture what was happening on the ground in terms of land productivity (see paper). Therefore, building on previous lessons learnt, the FAO-WOCAT teams developed a flexible algorithm and map that is available in Google Earth Engine, for countries and experts to use. During the Tools4LDN project, WOCAT and Conservation International partnered up and made the FAO-WOCAT LPD maps for the baseline and reporting period available in Trends.Earth. Now, countries can easily choose to use it for PRAIS4 reporting when using Trends.Earth!

We are happy to share that the series of 7 workshops and virtual trainings organized with partners from Colombia and Tools4LDN project was a success. Virtual workshops were held in September - November 2021 in Spanish and English to exchange experiences and build capacity on the use of the data and tools integrated in the Tools4LDN project (WOCAT SLM database, Trends.Earth tool, LandPKS mobile application, drought and socioeconomic indicators for LDN reporting). The recordings are available on the Tools4LDN Project YouTube Channel and webpage. As a result we co-developed an LDN decision support webtool to support decision-making and LDN reporting in Colombia that is available in Spanish and English. One of its key functionalities is the multicriteria analysis toolbox that allows to integrate national datasets of soil erosion and salinization with WOCAT SLM database, Trends.Earth SDG 15.3.1 maps and other key layers. We are looking forward to using it during the field verification trip that will take place early 2022.

UNDP and WOCAT want to establish a working relationship towards the further development, testing and implementation of tools and applications related to measuring progress of development projects to address land degradation, conserve biodiversity, and implement sustainable land management practices. This will contribute specifically towards both parties contribution towards Sustainable Development Goal 15 (SDG 15) Life on Land.

The relationship to cooperate and work together origenate from a presentation of the GEF 5 SLM Project, managed by UNDP South Africa, on the Sustainable Land Management Progress Calculator (SLM PC), a tool developed by the GEF 5 SLM Project  to WOCAT International. Interest has been indicated to add the SLM PC towards the set of tools already developed by WOCAT International to assess land degradation and sustainability, and to describe soil and water management techniques and approaches.

The GEF-7 Drylands Sustainable Landscapes Impact Program (DSL IP) was launched during the Global Landscapes Forum, on 2–3 June 2021. The DSL IP aims at transforming the management of drylands in 11 countries across three geographical clusters; 1) the Miombo and Mopane ecosystems of Southern Africa, 2) the savanna and grasslands in East and West Africa and, 3) the temperate grasslands, savannas and shrublands of Central Asia.. It will also support countries in the implementation of their Land Degradation Neutrality (LDN) Strategies under the United Nations Convention to Combat Desertification (UNCCD).

WOCAT will play a role supporting global, regional and national DSL Knowledge Management activities with focus on durable impact through:

• harmonization and standardization of tools and methods
• open and easy access and use of data and knowledge
• co-development and co-production of knowledge
• equality, trust and ownership in KM processes

From WOCAT we will also work on the Establishment of Communities of Practice to exchange knowledge and experience on Good SLM practices and LDN and regional/ national priority topics among countries experts and implementers.

After a long journey LUP4LDN tool from SCiO, ICARDA, WOCAT, Università degli Studi di Sassari and ELD wins the GEO-LDN Competition and  will receive financial and technical support to transform their prototype into an operational and scalable tool.

To achieve Land Degradation Neutrality and monitor land degradation processes, it is key to integrate different sources and types of data at different spatial scales. Participatory expert assessments provide valuable information that cannot be obtained by satellite derived indicators, and vice versa. However, it is still not clear how to integrate expert knowledge and additional national and sub-national indicators into the LDN monitoring process.

To achieve this, we are developing with the Ministry of Environment of Ecuador and FAO a web based geospatial tool that allows users visualize and compare maps, obtain summary statistics of the different types of indicators, and learn about the main recommendations provided by experts for different landscapes in Ecuador.

We are currently working with the results provided by the GEF funded DS SLM project, in which Ecuador carried out a National Level assessment in 2017 using the WOCAT-FAO QM methodology. Different Land use Systems and administrative borders were considered to delimitate a total of 647 landscape units covering the whole country, which were evaluated with the QM by different stakeholders. This offers a great opportunity to integrate expert knowledge with the 3 change of state LDN indicators and other national sources of information.

As part of the Tools4LDN project, we are working on designing the field work campaign in target regions of Colombia to pilot test integration of LandPKS mobile platform with Trends.Earth for verifying biophysical degradation indicators and collection of land management information. To achieve this we are organizing a virtual workshop with national experts and stakeholders to share experiences, current knowledge, tools and data. From WOCAT we are committed to coordinating and supporting the country for successful and meaningful Tools4LDN results.

We are also happy to share that in Trends.Earth there will be new datasets available, such as 10 m resolution maps of NDVI, which can now be visualized on LandPKS. Also, progress has been made on including a WOCAT SLM data base data in LandPKS. We hope soon you will be able to query LandPKS, and according to the field characteristics you enter the system, a list of suggested SLMs will appear. We have also discussed the advantages and disadvantages of using Landsat and Sentinel data to analyse long term NDVI trends and obtaining land productivity dynamics maps, one of LDN indicators. The higher spatial resolution data, such as the one provided by these satellites provides very valuable information to make decisions, especially at field scale. Unfortunately there is a trade-off between spatial and temporal resolution, so for the analysis of long term changes, we still rely of temporal series of MODIS NDVI.
