The four days Participatory Workshop on National Reporting to the United Nations Convention to Combat Desertification (UNCCD), which began on 9th January 2023 came to close on 12th January 2023. The workshop was attended by national experts from eight key agencies – Department of Livestock, National Statistical Bureau, Department of Forests and Park Services, National Land Commission Secretariat, National Biodiversity Centre, Department of Geology and Mines, National Centre for Hydrology and Meteorologyand the National Soil Services Centre. Given the technical nature of the workshop coupled with lack of national data and capacity, the National Soil Services Centre (NSSC), as the National Focal Agency of the Royal Government of Bhutan to the UNCCD, has engaged experts from the World Overview of Conservation Approaches and Technologies (WOCAT) to facilitate and guide the workshop. While the overall objective of the workshop was to improve the default data sets for the national reporting, the specific objectives of the workshop were:

  • Define in participatory way the most appropriate legend and data source to map degradation due to cover changes in Bhutan;
  • Identify which land cover changes correspond to either degradation, improvement or neutral transitions (transition matrix) and obtain the final map of degradation due to land cover changes integrating national experts’ knowledge;
  • Select in a participatory way of the most representative map of land productivity dynamics for the Kingdom of Bhutan;
  • Define the strategy to improve the estimation of SOC changes;
  • Select the most appropriate methodology for the comparison of the degradation maps of the baseline and reporting period; and
  • Identify false positives and negatives and hotspots of degradation using the Bhutan LDN DSS.

The workshop was held at the Hotel River Valley in Punakha in a mixed mode – participants in person and facilitator in virtual.

During the workshop, participants discussed and made the necessary decisions to select the best available land cover, land productivity dynamics and Soil Organic Carbon (SOC data,) as well as the most appropriate algorithms to analyze these data sets, following UNCCD’s PRAIS4 reporting manualguidelines and the SDG 15.3.1 Good practice Guidance.

Land cover data to map transitions and degradation due to land use change (sub-indicator SO1-1) was explored using a specifically developed tool based on a Google Earth Engine (GEE) application that allowed users to compare the default land cover data from the European Space Agency and the GlobeLand30 2020, the 30-meter resolution global land cover data product developed by China.

Five different land productivity dynamic maps were compared using another Google Earth Engine application developed for this purpose, where users could obtain statistics at national and district level in order to compare assessments and accordingly identified the most representative map.

Finally, the participants looked atthe LDN Decision Support System (LDN DSS) which is being codeveloped to integrate national information on SLM, land cover, SOC, and land degradation with global indicators on Biodiversity, climate change and LDN. This tool was also used to map hotspots and false positives and negatives for PRAIS4 and to contribute to informed decision making to achieve national LDN targets in future.

The workshop was a great success for which the NSSC would like to thank WOCAT team for their technical inputs and the participants from different agencies for their sincerity and commitment in the workshop.
