Abstract

This article discusses the importance of quality deforestation area estimates for reliable and credible REDD+ monitoring and reporting. It discusses how countries can make use of global spatial tree cover change assessments, but how considerable additional efforts are required to translate these into national deforestation estimates. The article illustrates the relevance of countries’ continued efforts on improving data quality for REDD+ monitoring by looking at Mexico, Cambodia, and Ghana. The experience in these countries show differences between deforestation areas assessed directly from maps and improved sample-based deforestation area estimates, highlighting significant changes in both magnitude and trend of assessed deforestation from both methods. Forests play an important role in achieving the goals of the Paris Agreement, and therefore the ability of countries to accurately measure greenhouse gases from forests is critical. Continued efforts by countries are needed to produce credible and reliable data. Supporting countries to continually increase the quality of deforestation area estimates will also support more efficient allocation of finance that rewards REDD+ results-based payments.

Highlights

  • This article discusses the importance of quality deforestation area estimates for reliable and credible REDD+ monitoring and reporting

  • REDD+ is the provision of financial resources to developing countries that slow, halt, and reverse deforestation, referred to as “results-based finance”. Such finance is dependent on National Forest Monitoring Systems (NFMS) that are accessible, transparent, reliable, credible, and can support national processes [6], including providing data and information for REDD+ reporting

  • As countries were invited to report on REDD+ to the UNFCCC, many started by building on existing land cover analyses

Summary

The Important Role of Forests in Climate Change Mitigation

Publisher’s Note: MDPI stays neutral with regard to jurisdictional claims in published maps and institutional affiliations. To avoid dangerous climate change, we need to reduce emissions from deforestation and forest degradation in the short term and restore forests to remove carbon from the atmosphere in the longer term. Determined Contributions (NDCs), under the Paris Agreement Many such targets include forest-related greenhouse gases (GHGs). One important vehicle for climate change mitigation through forests is REDD+ (Reducing emissions from deforestation and forest degradation and the role of conservation, 4.0/). REDD+ is the provision of financial resources to developing countries that slow, halt, and reverse deforestation, referred to as “results-based finance” Such finance is dependent on National Forest Monitoring Systems (NFMS) that are accessible, transparent, reliable, credible, and can support national processes [6], including providing data and information for REDD+ reporting. This article discusses data quality in monitoring forest area changes for REDD+ reporting
