    Forest Monitoring and Assessment for Climate Change Reporting: Partnerships, Capacity Building and Delivery 2007
    Also available in:
    No results found.

    This working paper was prepared in light of the upcoming Conference of the Parties of the UNFCCC in December 2007 to inform about the status and ongoing efforts in the field of forest monitoring, assessment and reporting at national and international levels. Part I is a review of partnerships between FAO and countries for building capacity and supporting implementation of forest monitoring, assessment and reporting, to meet requirements at national and international levels. At national level, FA O works with countries to establish long-term and robust monitoring systems, based on systematic field sampling and data collection. At international level, FAO supports countries to report to the Global Forest Resources Assessments, which is the leading global reporting process on forests, their management and use. Part II presents basic requirements for national forest monitoring systems, seen from a broader policy context. It reviews the current status in countries with respect to two variabl es that are important for climate change reporting – forest area changes and forest carbon stock. It is concluded that in most developing countries the quality of current forest monitoring would not be satisfactory for an accounting system of carbon credits. However, it is also suggested that investment in national forest monitoring is attracting greater interest, as exemplified by the increasing number of countries requesting support from FAO. FAO continues to work in close collaboration with i ts member countries to improve forest monitoring, assessment and reporting, including helping them to meet requirements for forest carbon reporting.

    Evaluation of the project "System for Earth Observation Data Access, Processing and Analysis for Land Monitoring" (SEPAL)
    Project code: GCP/GLO/537/NOR

    The System for Earth Observation Data Access, Processing and Analysis for Land Monitoring (SEPAL) is a cloud-based computing platform for fast access and processing of remotely sensed data sources. It is designed to assist national forest monitoring and reporting for the Reducing Emissions from Deforestation and Forest Degradation, Forest Conservation, Sustainable Management of Forests and Enhancement of Carbon Stocks in Developing Countries (REDD+) mechanism. The terminal evaluation of the project found SEPAL to have been largely successful and relevant in achieving its aims. The evaluation recommended certain improvements, notably a “plan B” option to mitigate SEPAL’s dependency on Google Earth Engine, and assurance of continued relevance in Phase II of SEPAL.

    Trees, forests and land use in drylands: the first global assessment
    Full report
    2019
    Also available in:
    No results found.

    Drylands cover 41 percent of the Earth's land surface. This publication presents the results of the first global assessment of trees, forests and land use in these lands. The assessment breaks new methodological ground: it relies on the visual interpreation of freely available satellite images, carried out by more than 200 experts in a series of regional workshops. Using a tool called Open Foris ollect Earth, developed by FAO in collaboration with Google, participants gathered and analysed information for mrore than 200 000 sample plots worldwide. For each region, the report summarizes the distribution of forests, other wooded land and other land uses including grasslands, croplands, built-up areas and barren land, across all drylands and by aridity zone. It also estimates tree canopy cover, shrub cover, forest type and presence of trees outside forest. Indicatng that the global drylands contain more than one-quarter of the world's forest area, and that trees are present on 31 percent of the world's dryland area, the report provides a baseline for future monitoring and will support countries in their efforts to identify appropriate investments for the restoration and sustainable management of drylands.
