|Course Title||Environmental Impact Assessment of Economic Projects|
|Institution||Vladivostok Pacific Institute of Geography|
I. Aim of the course
The aim of the course involves providing students with comprehensive theoretical knowledge of EIA for economic projects (contents, principles, implementation stages, EIA techniques, peculiarities of different kinds of environmental impacts, a character of hazardous natural process impacts of human activity, etc.) and some skills in EIA performance.
II. Role of the course in the overall degree curriculum
In recent years the demand is growing for experts who are capable of solving problems in the field of regional natural management (natural resource management, grounds for invested projects of natural management, environmental protection and restoration, etc.). In order to train such experts in field work, general and specialized lecture courses are needed. The course "Environmental Impact Assessment of Economic Projects" is an important component link in the curriculum system for this discipline.
III. Methods used
Low material provision reduces significantly possibilities for the application of various pedagogical techniques. Illustrations on transparencies are widely used when delivering lectures. The lectures themselves are not continuous monologue, rather, a feedback principle is used in the form of individual questions to the audience to stimulate their thinking. When holding a seminar devoted to EIA techniques, implementation of some large-scale practicable project is used as a model. The students are informed of the natural conditions of the territory, specifications of the project are provided and typical environmental impact of similar projects is described. Thereafter, each of the students is asked to implement EIA of this project himself applying some technique (for instance, the Leopold matrix). Once the matrixes are filled in, discussion of the results and their comparison with real consequences of implementing the project is conducted.
