The present study assesses the remote sensing challenges experienced by the project developers for operational monitoring of REDD+ (Reducing Emission from Deforestation and Degradation) projects. The study was carried out at a sample of 20 REDD+ projects in Brazil, Peru, Cameroon, Tanzania, Indonesia and Vietnam using a questionnaire survey and regional workshops on MRV (Monitoring, Reporting and Verification). The assessment showed that eleven project developers (55%) showed high or very high remote sensing and GIS capacity, seven (35%) were ranked medium, and two (10%) were ranked low. At the regional level, capacity tended to be highest in the projects in Brazil and Peru and somewhat lower in Cameroon, Tanzania, Indonesia and Vietnam. The study calls for an increased investment and capacity building to meet the various remote sensing challenges in REDD+ projects.
