Excerpt
In 1997, the International Institute for Applied Systems Analysis (IIASA), Food and Agriculture Organization (FAO) and the International Soil Reference and Information Centre (ISRIC) identified the need for refinemaent of the agro-edphic element in the revision of FAO's Agro-Ecological Zones (AEZ) methodology and in IIASA's Land Use Change and Land Cover project for Europe and Northern Eurasia (LUC). The resulting study was based on the analysis of the 4353 soil profiles in version 1.0 of ISRIC's World Inventory of Soil Emission Potential (WISE) database. It led to the development of a set of files holding 'derived soil data for use in global and regional AEZ studies'. The study further identfied several geographic, taxonomic and soil physico-chemical gaps, showing the persisting need for expanding the set of soil profile data available for this kind of analyses.
The current study uses all profiles held in WISE, version 1.0, to which have been added profiles extracted from currently available soil and terrain (SOTER) databases.
