Trend of Inventory Data Developments of Water Resources

Abstract

Amid growing interest in water resource issues, evaluation methods for sustainable water resource use has been studied. For environmental impact assessment of water resources, LCA practitioner have to collect the inventory data related to water resources in primary data collection, and also the inventory data of water resources is essential in the background database. So, we added the water resources inventory data to our inventory database IDEA (Inventory Database for Environmental Analysis) ver.2. IDEA ver.2 prepared about 3,800 process data and equipped with high level the comprehensiveness, completeness, representativeness and transparency. To expand the water resources inventory in IDEA, it was considered largely contribute to water resources assessment. In this paper, for the Japanese LCA practitioner, the differences of concept between the water resources data in foreign inventory database and IDEA were explained. And I introduce the concepts and the way of data creation of IDEA.
