Book (stand-alone)Trees, forests and land use in drylands: the first global assessment
Full report
2019Also 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. -
DocumentFRA 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. -
Book (stand-alone)Global forest land-use change from 1990 to 2010: an update to a global remote sensing survey of forests 2017
Also available in:
No results found.Monitoring the Earth’s global forest resources is important. This note presents the latest results for the extent of forest-land and changes in forest land use for the time period 1990 to 2010. The work is the result of a partnership between FAO, its member countries and the European Commission Joint Research Centre (JRC).
