Description: The Global Administrative Unit Layers (According to FAO GAUL global country boundaries modified for use by ILRI, Version 1r2.). This layer was developed in the framework of the 'Drivers of change in mixed crop-livestock systems' study. The CGIAR Systemwide Livestock Programme (SLP) commissioned a 1-year desk study on 'Drivers of change in mixed crop-livestock systems'. The study was conducted by a multi-disciplinary task force from across the CG centres. The study consisted of 1) developing a conceptual framework for studying the effects of drivers of change in mixed systems, 2) analysing the past trends in key indicators in mixed crop-livestock systems change, 3) using the trends, modeling approaches and other tools, to develop a series of scenarios of how mixed systems in different regions might evolve. This will enable the identification of what their constraints would be and what could be their opportunities. For a number of socio-economic and production indicators the current situation is compared with future projections under different scenarios. These indicators are mapped and summaries per region and production system produced. The production of the maps and regional summaries follows a 2-step process. In a first step, the IMPACT model is used to produce future projections of -amongst others- crop and livestock production, water use, world prices, income and malnutrition. The output of the IMPACT model is at country level or food production unit (FPU) level. A second step then applies GIS technology to spatially re-allocate the country and FPU level outputs from IMPACT to different livestock production systems within countries and regions. This version is an updated version of gaul08_ilri_v1r.shp that had duplicated FAO_STAT2 codes due to small islands that do not get the same GAUL admin0_codes (each is unique). So the island codes have been changed to negative versions while the "real" country fao_stat2 code remains positive for linking with external tables. Version 1r2 works with current FAOSTAT coding for China, and also for Serbia and Montenegro joined (FAOSTAT=186). GAUL gives a different FAOSTAT code for China (41) and separates Serbia and Montenegro that do not yet have FAOSTAT codes as separate entities. This database works best currently with FAOSTAT country-level databases.
