Multiple environmental stresses including global environmental changes, e.g. global warming and ocean acidification, and local anthropogenic stresses, e.g. water pollution, are seriously affecting various ecosystems. In order to understand these effects quantitatively, it is necessary to understand the sustaining mechanisms of global and local environmental systems and ecosystems, and the processes of ecosystem responses to various environmental stresses. Moreover, understanding the actual situation concerning the effects of global/local-scale environmental stresses on ecosystems, and elucidating the relationship between the causes and the socio-economic structure are also needed. Then, to develop a sustainable social system by conserving ecosystems, it is important to elucidate the interactions between the social-system, which has two dimensions as a stress source and a stress controller, and the ecosystem, and to consider the entire system as a socio-ecological system.
The aim of this class is to understand the sustaining mechanisms of global and local environmental systems and ecosystems, to understand ecosystem dynamics under multiple environmental changes and environment-ecosystem interactions, and to understand the importance of understanding environmental problems in a socio-ecological system framework. For this purpose, the necessity of integrating various/broad/comprehensive points of view is shown through several case studies. Through lectures and group discussions on selected themes, students are expected to acquire the abilities to understand problem structures from such various viewpoints and propose solutions.
By the end of this class, students will be able to:
(1) understand the sustaining mechanisms of global and local environmental systems and ecosystems,
(2) understand ecosystem dynamics under multiple environmental changes and environment-ecosystem interactions,
(3) understand the importance of understanding environmental problems from various/broad/comprehensive points of view in a socio-ecological system framework,
(4) acquire the abilities to understand problem structures from various viewpoints and propose solutions.

|✔ Specialist skills||Intercultural skills||Communication skills||✔ Critical thinking skills||Practical and/or problem-solving skills|
From class 1 to class 11 of this course, lectures about each topic are scheduled. In the last 4 classes, group discussion about case studies of actual projects will be held. At the end of this course, presentations will be made to summarize the discussions, and the results will be compiled in a report.
