    Global forest land-use change 1990-2005: Initial results from a global remote sensing survey 2005
    Also available in:
    No results found.

    The use of satellite imagery can substantially improve knowledge on changes in forest area as a result of deforestation, afforestation and natural forest expansion. This summary outlines some of the initial findings on forest land use and land-use change of a global remote sensing survey carried out to complement the country reporting process as part of the Global Forest Resources Assessments led by the Food and Agriculture Organization of the United Nations (FAO).

    FRA 2000 - Pan-tropical survey of forest cover changes 1980-2000 - Results and findings 2002
    Also available in:
    No results found.

    The results from the FRA 2000 Remote Sensing Survey cover most of pan-tropical forests under a wide range of ecological conditions, from tropical rainforests to dry forests. Estimates were calculated at different levels: at sampling unit, stratum, sub-regional, regional, pan-tropical levels and at ecological zones level. The reliability of the estimates differs according to the study level. The survey was mainly designed for generating information with an acceptable statistical precision at the regional and pan-tropical levels. Estimates at the subregional level have a relatively low precision but give valuable indications on forest changes processes.

    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.
