This course is intended to convey investigative analysis methods pertaining to environmental technoscience and environmental policy. Environmental issues are vast and span the natural and social sciences fields. In this course, students gain the ability to approach interdisciplinary subjects while dealing with practical environmental issues. The key significance of this study lies not in acquiring individual techniques or methods as much as in reaching the final objective―gaining a comprehensive ability to resolve environmental problems by gaining a comprehensive understanding of an issue, knowing how to create a framework while under time and resource constraints, and understanding which issues must be dealt with first. It is fundamentally impossible for a specialist to tackle a complex environmental problem on his or her own. It is necessary to meet challenges through collaboration with a variety of specialists and stakeholders. This course aims to nurture environmental leaders, who must be able to understand the core and scope of the problems and understand the output provided by specialists. They must manage their teams comprehensively in order to execute practical measures to resolve problems. Students gain an understanding of the relevant methods in this course and develop comprehensive abilities by taking on projects as a form of practical training.
