6.88. 2010 Africa Agriculture Resources Sensitivity Index Distribution Map#
The“agriculture resources sensitivity” represents the agriculture potential in 2010. This potential is measured by the availability of land and food production per capita, and the main thread to agriculture land, represented by desertification risk. The index results from the second cluster of the Principal Component Analysis preformed among 16 potential variables. The analysis identify four dominant variables, namely “potential rain-fed food production per capita”, “cropland crowding”, “desertification index” and “topographic resources availability”, assigning respectively the weights of 0.29, 0.29, 0.27 and 0.15. Before to perform the analysis all the variables were log transformed to shorten the extreme variation and then were score-standardized (converted to distribution with average of 0 and standard deviation of 1; all variables with inverse method except “desertification index”) in order to be comparable. Data in raster format (resolution 0.5 arc-minute). Coordinate system: WGS 84. Data source: https://data.apps.fao.org/map/catalog/srv/eng/catalog.search#/metadata/e74668b3-6ee8-4167-89cf-b15f8ebf515e
