Integrated Environmental
Assessment Sub-Project

Figure of AIM Model Development for APEIS. For the APEIS purpose, several models have been developed based on the AIM family shown above, those are AIM/Trend, AIM/CGE, AIM/Material, AIM/Energy (AIM/End-use and AIM/Local/Country/Inter-Provincial), AIM/Ecosystem, and AIM/Water. These models are integrated and applied to the assessment of innovation strategies in the Asia-Pacific region, such as New Environmental Market Establishment, New Enviromental Technology Development, New National Land Conservation Strategies, New Environmental Infrastructure Establishment and New International Cooperation Arrangement.

AIM ⁄ Trend & AIM ⁄ CGE

AIM/Trend is a multi-regional model based on a simple structure to project the conditions of the economy, energy and the environment for the target year 2032. It will be applied to the assessment of future trends of the economy and the environment and their mutual interactions, for all 42 countries in the Asia-Pacific region. The AIM/CGE model is a multi-regional, multi-sectoral, computable general equilibrium (CGE) model. It will be used to assess the environmental and economic effects of new market establishment, new investment, technology transfer, and international trade.

AIM ⁄ Material

AIM/Material is a country-based CGE model dealing with environmental investment and environmental industry. In order to support AIM/Material, a bottom-up technology model will be constructed. The main feature of AIM/Material is in the integration between monetary and material balances, including waste recycling.

AIM ⁄ Energy

AIM/Energy is a country-level bottom-up model that reproduces the technology selection process for energy supply and demand. Four hundred technologies listed in the model will help to determine the best mix of technologies, in consideration of future socio-economic trends. This model has already been applied to Japan, China, India and Korea, and there are now plans to apply it to ASEAN countries.

AIM ⁄ Ecosystem

AIM/Ecosystem is a set of computer models that simulate vegetation dynamics, water discharge, agricultural productivity, natural processes of ecosystem change, land use change, and socio-economic change (such as health and economic impacts) caused by ecosystem change. These models can be linked to each other for integrated assessments of total ecosystem change.

AIM ⁄ Water

AIM/Water is one of the AIM/Ecosystem components which reproduces the processes of discharge and pollution. It will have a specific component of city-environment interactions to assess in greater detail the effects of innovation strategies for large Asian cities.
