The aim of this unit is to introduce to students the idea, methodology and basic tools of environmental modeling. Models are important tools in environmental studies and management nowadays. In order to better understand environmental systems, to predict their behaviour and to develop effective management strategies it is necessary to bring together ecological, socio-economic and technological aspects of environmental problems. Some most often used tools to secure such an interdisciplinary analysis of numerous factors are system dynamics and process-based modelling techniques. The models can also be used to stimulate consensus-building among various experts and to facilitate more explicit and comprehendible communication of findings to decision-makers. Though different alternative approaches to environmental modelling are to be discussed the course mainly focuses on practical skills in process-based simulation.
This course consists of laboratory-based lectures, readings, in-class exercises, homework, in-class and individual consultations and a major project (assignment). The course is based on "learn-by-doing" approach: the principles and tools described during the laboratory-based presentations will be by accompanied by students' individual work in the class. The students will develop understanding of complex environmental systems by constructing their own models using STELLA simulation software package. This is user-friendly software for visual modelling which allows non-programmers and non-mathematicians to develop environmental models. Ideally, models are based on students' academic and professional background and can be used later for their thesis research.
