World Inventory of Soil Emission Potentials (WISE)
Example of WISE-derived soil data (0.5 x 0.5 degree grid)
The WISE project, and various follow-up activities, has developed homogenized sets of soil data, linked to a spatial data set, relevant for a wide range of environmental studies at global scale - agro-ecological zoning, assessments of crop production, soil vulnerability to pollution, soil carbon stocks and change, and soil gaseous emission potentials (see: WISE-related publications).
The WISE project (1991-1996) was implemented by ISRIC for the Dutch National Research Programme on Global Air Pollution and Climate Change (NRP Project 851039); it involved collaboration with numerous institutions and individuals worldwide. Some 1000 profiles from WISE, version 1.0, were used by the Global Soil Task Force, coordinated by the International Geosphere-Biosphere Programme Data and Information System (IGBP-DIS).
Upon completion of the NRP-project, in 1996, WISE has been maintained and expanded in the context of several externally funded projects. Follow-up activities, with IIASA and FAO (PDF) and IFPRI (PDF), were aimed at deriving revised soil property estimates for the soil units of FAO's (1995) 1:5 million scale Soil Map of the World at 0.5 by 0.5 degrees , respectivley 5 by 5 arc-minutes  resolution.
Profile data from WISE are also used to fill gaps in primary SOTER databases, resulting in so-called SOTWIS databases. The latter were used to populate large portions of the Harmonized World Soil Database (HWSD ).
In 2009, WISE 3.0 holding some 10,253 profiles has been made available on-line. Recently, the WISE database is being consolidated and used in the framework of the Carbon Benefits Project, co-funded by the Global Environmental Facility (GEF).
