Potential to sequester additional carbon in soils on cropland

Sun, 24 Jun 2007 22:00:00 GMT

The map is a global raster datalayer with a resolution of 5 arc-minutes. It provides a preliminary perspective on where cropping systems could be changed to achieve substantial soil carbon sequestration. It highlights the intersection of locations with medium-to-high soil carbon sequestration potential and croplands, as identified by the GLC2000 global land cover database. The data sources are from FAO and GLC2000 database.

Croplands with high rates of human-induced erosion

Sun, 24 Jun 2007 22:00:00 GMT

The map is a regional (South and Southeast Asia ) raster data layer with a resolution of 5 arc-minutes. It shows croplands in South and Southeast Asia with high levels of sheet erosion. This provides an indication of potential off-site impacts in the form of siltation and sedimentation in waterways. The map is based on the Assessment of the Human Induced Soil Degradation in South and South East Asia conducted between 1994-1997 by the International Soil Reference and Information Center (ISRIC) and FAO. The data sources are from FAO and ISRIC.

Biodiversity hotspots in areas poorly suited to rainfed agriculture with high poverty rates

Sun, 24 Jun 2007 22:00:00 GMT

The map is a global raster datalayer with a resolution of 5 arc-minutes. It shows areas of biodiversity hotspots on croplands poorly suited to rainfed agriculture which also have high poverty rates. Poverty rates areas are mapped using the datasets on stunting amongst children under five dataset (FAO). The stunting indicator is based on an estimate of the distribution of chronic undernutrition at national and sub-national levels using stunting in growth among children under five years of age. Areas with over 40 percent prevalence of stunting amongst children under the age of five are shown. The data sources are from FAO.

Highly degraded croplands with soil carbon sequestration potential and high poverty rates

Sun, 24 Jun 2007 22:00:00 GMT

The map is a regional (South and Southeast Asia) raster data layer with a resolution of 5 arc-minutes. It shows locations in agricultural production in South and Southeast Asia that are highly degraded as well as highly degraded areas that also have a medium to high soil potential for carbon sequestration.

Projected expansion of cropland and pasture, 2000-2010

Sun, 24 Jun 2007 22:00:00 GMT

The map is a regional (Neotropics) raster data layer with a resolution of 5 arc-minutes. The map gives 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.

Projected expansion of cropland and pasture to lands poorly suited to rainfed agriculture, 2000-2010

Sun, 24 Jun 2007 22:00:00 GMT

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.

Biodiversity hotspots on croplands poorly suited to rainfed agriculture

Sun, 24 Jun 2007 22:00:00 GMT

The map is a global raster datalayer with a resolution of 5 arc-minutes. It overlays information about areas considered biodiversity "hotspots", with information on suitability for agriculture and on current land use patterns. Biodiversity hotspot maps are generated by Conservation International. Conservation International 2005.

Farming system classes in developing and transition countries, 2000 (FGGD)

Wed, 20 Jun 2007 22:00:00 GMT

The FGGD farming system classes map is a global raster datalayer with a resolution of 5 arc-minutes. Each pixel is classified as belonging to one of seven farming system classes, aggregated from the original 45 farming systems contained in the farming systems map.

Irrigated area and land not currently available for rainfed agriculture, total (FGGD)

Mon, 11 Jun 2007 22:00:00 GMT

The FGGD total currently available land map is a global raster datalayer with a resolution of 5 arc-minutes. Pixels classified as urban, closed forest, or irrigated are indicated as land not currently available for rainfed agriculture. All remaining pixels classified as other land represent land currently available for rainfed agriculture. 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.

Irrigated area and land not currently available for rainfed agriculture, by land cover type (FGGD)

Mon, 11 Jun 2007 22:00:00 GMT

The FGGD currently available land map by land cover type is a global raster datalayer with a resolution of 5 arc-minutes. Each pixel is classified as urban, closed forest, irrigated or other land, that is considered available for rainfed agriculture. 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.

Occurrence of cropland (FGGD)

Mon, 28 May 2007 22:00:00 GMT

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.

Farming Systems by Regions

Fri, 28 Feb 2003 23:00:00 GMT

Farming systems map made originally in 6 different regions, digitized from paper maps, classified according to John Dixon and used by Chris Aulrich to prepare the Farming Systems and Poverty project (FAO, World Bank, 2001).
