Water stress assessment by coupled simulation of Integrated Land Simulator (ILS) and Integrated Assessment Model (IAM)

Abstract

Toward realizing global sustainability, there is an increasing need to reproduce and evaluate the complex interactions between the environment and economic activities on a computer system. In this study, we focused on land use change and its impact on the water cycle and observed the change in water stress by coupling the integrated land simulator ILS and the integrated assessment model GCAM. Consequently, our system has the potential to suggest the timing and location of severe environmental impacts in terms of water resource use with a spatiotemporal resolution that could not be predicted when ILS and GCAM were run independently.
