Course description and aims

In order to understand recent global climate change and associated ecosystem changes, and to predict the future, it is necessary to understand the climate change history and the global environmental system. Ecosystems respond to environmental conditions. On the other hand, we need to understand that environment can also be affected by ecosystems. Therefore the interaction between environment and ecosystems is also an important factor for the environmental system. In this course, historical changes of past-present-future climate and driving forces in each time scale are reviewed, and some monitoring and estimation techniques for past and present environmental parameters are explained.
The aims of this course are (1) to understand the past-present-future history of climate change, its driving force and an overview of the global environmental system, (2) to understand ecosystem dynamics under various environmental conditions and environment-ecosystem interactions, (3) to acquire modeling skills for ecosystem phenomena and mechanisms, and (4) to acquire basic skills for numerical simulation of the model.

Student learning outcomes

By the end of this course, students will be able to gain insights into the background mechanisms of changing environments and ecosystem dynamics.


ecosystem, global environmental system, material cycle, modeling, numerical simulation

Competencies that will be developed

Specialist skills Intercultural skills Communication skills Critical thinking skills Practical and/or problem-solving skills

Class flow

For the first half part of this course, lectures about various topics are scheduled. For the second half, a mixed style of practices of MATLAB programming and lectures are scheduled.

Out-of-Class Study Time (Preparation and Review)

To enhance effective learning, students are encouraged to spend approximately 100 minutes preparing for class and another 100 minutes reviewing class content afterwards (including assignments) for each class.
They should do so by referring to textbooks and other course material.



Reference books, course materials, etc.

Handout will be distributed before the beginning of class via OCW-i.

Assessment criteria and methods

Learning achievement is evaluated by combining results from quizzes/short reports in every class (60 %) and homework (30 %), and report (10 %).
