Though forests play an essential role in international efforts to reduce greenhouse gas emissions, the development of systems to monitor deforestation and forest degradation has been slow. This is due to the demanding technical requirements and the large capacity gaps in many countries. Measuring and monitoring change on the ground and via satellite in a consistent way is no easy task.
Countries need to develop national measurement, reporting, and verification (MRV) systems to monitor progress towards achieving REDD+ goals. Establishing procedures to do so would be a significant outcome of the UN climate negotiations in Durban. This task falls to the Subsidiary Body for Scientific and Technological Advice (SBSTA).
