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). -
Book (stand-alone)Global forest land-use change 1990-2005 2012This report presents the key findings on forest land use and land-use change between 1990 and 2005 from FAO’s 2010 Global Forest Resources Assessment Remote Sensing Survey. It is the first report of its kind to present systematic estimates of global forest land use and change. The ambitious goal of the Remote Sensing Survey was to use remote sensing data to obtain globally consistent estimates of forest area and changes in tree cover and forest land use between 1990 and 2005. Overall, it fou nd that there was a net decrease in global forest area between 1990 and 2005, with the highest net loss in South America. While forest area increased over the assessment period in the boreal, temperate and subtropical climatic domains, it decreased by an average of 6.8 million hectares annually in the tropics. The survey estimated the total area of the world’s forests in 2005 at 3.8 billion hectares, or 30 percent of the global land area. This report is the result of many years of planning and three years of detailed work by staff at FAO and the European Commission Joint Research Centre, with inputs from technical experts from more than 100 countries. Many of these contributors now constitute a valuable global network of forest remote sensing and land-use expertise.

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.
