Subjects taught
Undergraduate Faculty Regional environmental informatics
In order to manage regional resources and environment properly, this course lectures collection of regional information, spatial analysis and show results visually using Geographical Information System (GIS). Student learn modern spatial data processing, development, and functions of geographic information systems (GIS); theory, concepts and applications of geographic information science.

Regional information programming
Develop statistical and analytical skills in the R programming environment to solve complex natural and sociological problems. R is free software, becoming popular for engineers, scientists, researchers recently. This course covers basic programming skills, statistical analysis and data visualization, but it also goes into data mining and basic spatial analysis.

Exercises in Regional Environment
This course exercise skills to solve problems in related to water resources utilization, regional environment planning and regional landscape planning. Students are committed to the attempt to adequately sort and find solution based on learning knowledge.

Graduate School:
Master’s Degree Course
Advanced Course of Regional Environmental Systems
Building sustainable regional society harmonizing with nature, this course lecture land and water resource utilization and management with watershed scale including urban, rural area, and argue ideal regional environmental systems related to resource recycling. This course provide collection and analysis on regional environmental information, building method for regional environmental planning, conservation and management on watershed network. Students will gain an understanding of the wide range of disciplines, approaches, debates, and ultimately professional opportunities in this field of endeavor.

Seminar on Environmental Science Ⅳ
Student exercise collection and analysis method for regional natural and sociological information, environmental planning, conservation and management of water resources. Students will develop an understanding of the various ecological, social and technological aspects of design and planning to create a sustainable region, in which human is harmonized with nature.
