Forests 2000 by Major Ecological Domains 2 July 2007 Along with the core information on state and changes in forests, FRA 2000 is reporting on various ecological aspects of forests. Forest resources information will be reported by ecological zone, which will contribute to understanding the implications of forest change on (ecosystem) biological diversity and carbon-cycling processes. The 2000 global ecological zone map has been developed, building upon the FRA 1990 experience for the tropics and extending the coverage to include the temperate and boreal forests. A globally consistent classification has been adopted, based on the Koppen-Trewartha climate system in combination with natural vegetation characteristics. A total of 19 global ecological zones have been defined and mapped, ranging from the evergreen tropical rainforest zone to the boreal tundra woodland zone. A main principle of delineating the global ecological zones involved the aggregation or matching of available regional ecological or potential vegetation maps into the global framework. [more]
Projected expansion of cropland and pasture, 2000-2010 25 June 2007 The map is a regional (Neotropics) raster data layer with a resolution of 5 arc-minutes. The mapgives an indication of areas at risk of conversion to agriculture in parts of South America. Wassenaar et. al. (2006) identified the areas at highest risk of conversion to pasture and croplands, using a model that explicitly incorporates dimensions such as location, suitability and various factors affecting relative economic values of land uses. The map identifies deforestation hotspot areas (at risk of conversion to pasture and cropland). The data sources are from FAO. [more]
 Projected expansion of cropland and pasture to lands poorly suited to rainfed agriculture, 2000-2010 25 June 2007 The map is a regional (Neotropics) raster data layer with a resolution of 5 arc-minutes. It gives an indication of areas of low agricultural suitability at risk of conversion to agriculture in parts of South America. Wassenaar et. al. (2006) identified the areas at highest risk of conversion to pasture and croplands, using a model that explicitly incorporates dimensions such as location, suitability and various factors affecting relative economic values of land uses. The map identifies deforestation hotspot areas (at risk of conversion to pasture and cropland) to lands poorly suited to rainfed agriculture. The data sources are from FAO. [more]
Occurrence of forest (FGGD) 29 May 2007 The FGGD land cover occurrence maps are global raster datalayers with a resolution of 5 arc-minutes. Each pixel in each map contains a value representing the percentage of the area belonging to the land cover type concerned. The method is described in FAO and IIASA, 2007, Mapping biophysical factors that influence agricultural production and rural vulnerability, by H. von Velthuizen et al. [more]
Occurrence of barren and sparsely vegetated land (FGGD) 29 May 2007 The FGGD land cover occurrence maps are global raster datalayers with a resolution of 5 arc-minutes. Each pixel in each map contains a value representing the percentage of the area belonging to the land cover type concerned. The method is described in FAO and IIASA, 2007, Mapping biophysical factors that influence agricultural production and rural vulnerability, by H. von Velthuizen et al. [more]

The World's Forests 2000 1 July 2001 The forest cover map is the first comprehensive worldwide view of forests, using a consistent methodology and standard data. The map has a resolution of 1 km and is based on 1992-93 and 1995-96 AVHRR data. Four broad land cover categories are presented following FAO standard classification: closed forest, open/fragmented forest, other wooded land and other land. [more]
