"Global Land Use and Land Cover Data for Integrated Assessment Modeling" by Ramankutty, Navin, Thomas Hertel and Huey-Lin Lee Abstract Changes in land use and land cover have been a major driver of global change over the last three centuries. Detailed spatially-explicit data sets characterizing global land cover changes are now emerging. By synthesizing remotely-sensed data with land use inventory data, the Center for Sustainability and the Global Environment (SAGE) is developing databases of contemporary and historical agricultural land cover change. These datasets are of immense value to the integrated assessment (IA) modeling community. One way to further enhance their value is by integrating them with global economic data in order to facilitate improved analysis of the costs of climate change mitigation. Towards this end, we are currently incorporating the SAGE land use data sets into the Global Trade and Analysis Project (GTAP) database. The GTAP database is currently the premier data set for economy-wide analysis of global economic issues and it has been widely used by the IA community. It includes detailed bilateral trade, protection, and energy data characterizing economic linkages among regions, as well as individual country input-output tables that account for inter-sectoral linkages within regions. Unfortunately, the current specification of land use in GTAP is rudimentary at best and does not distinguish between types of land. To incorporate the SAGE land use database into GTAP, we have divided each country’s land endowment into eighteen Agro-Ecological Zones (AEZs). This paper describes the procedure developed to integrate SAGE land use data, as well as some crop yield data from the Food and Agriculture Organization (FAO), to derive global national-level statistics on land cover and agricultural production by AEZ. The resulting database permits economists interested in IA to better assess the competition for land among agricultural activities and between agriculture and forestry. |
