Book (stand-alone)Trees, forests and land use in drylands: the first global assessment

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. -

Book (stand-alone)Trees, forests and land use in drylands 2016
Also available in:
Drylands cover about 41 percent of the Earth’s land surface and are home to 2 billion people, the majority of whom depend on forests and other wooded lands, grasslands and trees on farms for income and to meet basic needs. Yet surprising little is known about such ecosystems in drylands, despite widespread recognition of the need to restore drylands to cope with the effects of drought, desertification, land degradation and climate change. This document presents preliminary results of the first g lobal assessment of trees, forests and land use in drylands. It reports, among other things, that the global drylands contain 1.11 billion hectares of forest, which is more than one-quarter of the global forest area. There are also about 13.5 billion trees outside forests in drylands. More than 200 experts with knowledge of the land and land uses in specific dryland regions conducted the assessment, using freely available satellite imagery and a newly developed survey methodology. The pioneering study by FAO and many partners will be fully reported later in 2016.
