Thematic Guide to Integrated Assessment Modeling



The Asian-Pacific Integrated Model

Japan's National Institute of Environmental Studies (NIES) pursues collaborative research on global environmental change with other ministries, universities, and international research institutes (Japan Environment Agency 1994). NIES' center for Global Environmental Research, in collaboration with Kyoto University, has developed the Asian-Pacific Integrated Model (AIM) to study impacts of mitigation and adaptation scenarios in the Asia-Pacific region.

AIM comprises three interlinked modules: an emissions module, a climate module, and an impacts module. The emissions module consists of three separate country models for Indonesia, China, and Japan, which are then combined with an aggregate model of emissions in the rest of the world. These regional models determine anthropogenic greenhouse gas emissions using regional assumptions on population, technological, and economic growth to obtain estimates of energy consumption and land-use changes. Because the regional models are still under development, a more aggregate working version of the emissions module based on the Edmonds-Reilly-Barns model is being used until that work is completed.

Climate scenarios are produced using a variety of existing simple reduced-form models and results from prior Global Circulation Model (GCM) runs. Impacts of climate scenarios are estimated for agriculture, sea-level rise, water resources, public health, regional economics, and natural ecosystems. Impacts are represented spatially using a Geographic Information System (GIS). Development and applications of the AIM model are documented in Morita et al. 1994a, 1994b, and 1995.
