"Towards An Integrated Land Use Database for Assessing the Potential for Greenhouse Gas Mitigation" by Lee, Huey-Lin, Thomas Hertel, Brent Sohngen and Navin Ramankutty Abstract **NOTE** (10/31/2007) The documents below, Global Agricultural Land Use Data for Climate Change Analysis, Global Forestry Data for the Economic Modeling of Land Use, and An Integrated Global Land Use Data Base for CGE Analysis of Climate Policy Options supersede GTAP Technical Paper No. 25. Please refer to these documents over this paper. -------------------------------------------------------------------------------- This paper describes the GTAP Land Use Data Base designed to support integrated assessments of the potential for greenhouse gas mitigation. It disaggregates land use by agro-ecological zone (AEZ). To do so, it draws upon global land cover data bases, as well as state-of-the-art definition of AEZs from the FAO and IIASA. Agro-ecological zoning segments a parcel of land into smaller units according to agro-ecological characteristics, including: precipitation, temperature, soil type, terrain conditions, etc. Each zone has a similar combination of constraints and potential for land use. In the GTAP-AEZ Data Base, there are 18 AEZs, covering six different lengths of growing period spread over three different climatic zones. Land using activities include crop production, livestock raising, and forestry. In so doing, this extension of the standard GTAP Data Base permits a much more refined characterization of the potential for shifting land use amongst these different activities. When combined with information on greenhouse gas emissions, this data base permits economists interested in integrated assessment of climate change to better assess the role of land use change in greenhouse gases mitigation strategies. |

Special Instructions Release note: Release 2.0 (October 30, 2007): File name = 3592.zip ***Key improvements: A. updated SAGE land cover and land use data that include 175 crops vs. 19 reported in the Release 1.3 B. updated DGTM timberland area, forest carbon stock and land rent data C. revised approach to eliminating land rents in non-ruminants to preserve overall factor intensities in agriculture. D. revised approach to impose outside estimate of land rents in forestry. E. Therefore, all GTAP headers are revised accordingly. ***Data files: 1. GTPLU18V60_AGMP_DEC06.HAR: GTAP land rents, by 18 AEZ (Ref. point E above regarding revision in this release). 2. SAGE_DATA.HAR: SAGE land cover and land use data (Ref. point A and C above regarding revisions in this release). 3. DGTM_DATA.HAR: DGTM timberland area, forest carbon stock and land rent data (Ref. point B and D above regarding revisions in this release). **NOTE** (10/31/2007) The documents below, Global Agricultural Land Use Data for Climate Change Analysis, Global Forestry Data for the Economic Modeling of Land Use, and An Integrated Global Land Use Data Base for CGE Analysis of Climate Policy Options supersede GTAP Technical Paper No. 25. Please refer to these documents over this paper. ---------------------------------------- Release 1.3 (May 26, 2006): File name = 2680.zip ***Key improvements: A. revised timberland rent data of Canada and some Asian countries. B. revised timberland area data of Australia. C. Thus, GTAP "VFM" header of land rent is revised accordingly. See ReadMe_v1.3.txt for details.

B. revised tree species mapping: note that in this release there are 3 tree species--i.e., coniferous, broadleaf, and mixed--whereas earlier releases have no distinction between tree species. See ReadMe_v1.2.txt for details. Excel format of the data base is also provided and included in 2448.zip. ----------------------------------------- Release 1.1 (March 10, 2006): File name = 2408.zip ***Key improvement: A. revised Ecuador carbon stock data of release 1.0.
