  • Dryland map derived from the Aridity index map (P/PET).

  • The digital soil map for North and Central Eurasia region (covering China, Taiwan Province of China, Mongolia, CIS and the Baltic States) was prepared by FAO and IIASA in co-operation with: ? the Institute of Soil Science, Academia Sinica (Li Jin, Zhou House in 1978) for China and Taiwan Province of China (scale 1:4 million). ? the Pocveni Institute, V. Stolbovoy and B. Sheremet (1994) for Mongolia (scale 1:2.5 million) The original soil maps from China, Mongolia and CIS_BS have been merged by introducing DCW boundaries between: China-CIS_BS; China-Mongolia; Mongolia-CIS_BS. The original soil map of China includes the Chinese line between India and China, which extends beyond the Indian line, and the South China Sea islands (no soil information is present for the South China Sea islands). Those boundaries do not imply the expression of any opinion whatsoever on the part of FAO concerning the legal or constitutional states of any country, territory, or sea area, or concerning delimitation of frontiers.

  • Map showing 35 lengths of growing period zones for the developing world. Digital version of "Major Climatic Divisions" derived from the Agro-Ecological Zones Project, made by FAO in 1978. Refer to World Soil Resources Report 48, Vol. 1 Methodology and Results for Africa; Vol. 2 Results for Southwest Asia; Vol. 3 Methodology and Results for South and Central America; Vol. 4 results for Near East.

  • The compilation of a Soil and Terrain digital database for the South-African region forms a part of the ongoing activities of the Food and Agriculture Organisation of the United Nations (FAO) and the International Soil Reference and Information Centre (ISRIC) to update the world?s baseline information on natural resources. The updating of world soil resources, using the Soil and Terrain (SOTER) digital database methodology, is part of a global SOTER programme and intended to replace the FAO/Unesco 1:5 million scale Soil Map of the World (1971-1981). The African sheet of this map was published in 1973 and has been compiled on basis of information and data available at that time. It is understandable that a substantial part does not reflect the present state of knowledge of the soils in that region. The national institutes, responsible for the natural resources inventories, have been collecting a wealth of new information on the distribution and occurrence of soils in their region, which has resulted in updating their national soil maps mostly at scale 1:1 million, often applying the Revised Legend (FAO, UNEP, ISRIC, 1988) for the description of the mapping units. The International Union of Soil Science (IUSS) adopted an important change in the classification used for the map by introducing lower levels of subunits of the World Reference Base for Soil Resources (IUSS, FAO, ISRIC, 1998). This, together with the new soil data available at national level, justified such an update of the soil resources for the Southern African region.

  • Beta version of a thematic grid of Land Use Systems (LUS) and its attributes for Sub-Saharan Africa with a spatial resolution of 5 arc minutes or 0.083333 decimal degrees. This dataset, presented as beta version, is developed in the framework of the LADA project (Land degradation Assessment in Drylands) by the Land Tenure and Management Unit of the Food and Agriculture Organization of the United Nations and is copyright of FAO/UNEP GEF. The LUS map implementation is based on a innovative methodology combining more than 10 global datasets. Due to the map generation method, the quality of the map can never be uniform. The overall quality of the map depends heavily on the individual quality of the data for the different countries.

  • The SEA (Soil and Terrain Database Map of East Africa) is a Digital Soil Map at 1:1000000 scale for the following countries: Burundi, Djibouti, Egypt, Eritrea, Ethiopia, Kenya, Somalia, Sudan, Rwanda, and Uganda. Compilation of the SEA was subcontracted to ISRIC (Netherlands) by FAO in 1988. The main purpose, at that time, was to test the validity of the 1988 revision of the FAO/Unesco legend for the Soil Map of the World at 1:1 million scale. In 1990, the maps and the related tabular databases were automated (converted into digital form), in the FAO Geographic Information System Centre. The final version as been completed and made available in CD-ROM since 1998.

  • Recommended input level (for maize) for sub-saharean Africa based on the FAO-UNESCO Soil Map of the World.

  • Dominant soil map of Burkina Faso derived from the Digital Soil Map of the World.

  • The major source of geo-referenced soil data of Latin America and the Caribbean at a scale of 1:5 M is the Soil Map of the World (SMW) of FAO/Unesco (1974-1981). For this part of the globe the information was collected before 1974, the year of publication of the Latin American map sheets. Collection of soil survey information by the national institutes responsible for soil survey continued after publication and a large amount of new data is available at the national level. Since 1991 the FAO is actualizing the SMW information of Latin America with support from national soils institutes in the concerned countries. This has resulted in the acquisition of new 1:5 M soil maps of most Latin American countries. New soil maps with a revised soil classification legend (FAO, 1990) of Argentina, Brazil, Chile, Colombia, Ecuador, Mexico, Paraguay, Peru, Uruguay and Venezuela were obtained by FAO through subcontracts with the national soil institutes. Since 1988 the World Soils and Terrain Database Programme (SOTER) is operational in various Latin American countries at a scale of 1:1 M, in particular in Argentina, Brazil and Uruguay with UNEP funding. The major objective of the SOTER methodology is to use information technology, like geographic information systems and database management systems, for the creation of a world soils and terrain database with digital maps and attributes and their interpretations. At the moment SOTER databases at scale 1:1 M are available for the whole of Uruguay, the northern part of Argentina (460,000 km2) and the south of Brazil (100,000 km2). In 1992 FAO formally endorsed SOTER and decided to use the methodology to store and update soils and terrain data at a global level. The SOTER Procedures Manual was published jointly by FAO, ISRIC, ISSS and UNEP in 1993 and in the following year also as No. 74 in the series of World Soil Resources Bulletins. During the same year an agreement was signed between FAO and UNEP to develop a soils and terrain database of Latin America at scale 1:5 M, jointly with the updating of the SMW. ISRIC was asked to coordinate the activities of the SOTERLAC 1:5 M project in the countries to be included.
