These core specialised subjects will set the student up for the third year and provide the foundation for advanced laboratory skills.

Year 3

Modules focus on environmental systems and the interaction of humans, industry and development on the environment. Students will become competent in the areas of water and wastewater treatment, waste management, habitat and species management, environmental agricultural systems, environmental assessment, chemical toxicology, environmental microbiology and molecular biology. All modules have a practical emphasis preparing the student for the workplace and their work placement, which takes place at the end of this year.

Year 4

The fourth year of the honours degree programme is set on management principles so that the graduate has the skill to not only understand science and the environment but apply it practically with leadership and direction. The specialist topics covered include environmental planning, ecological and energy management systems, environmental legislation, science research methods and advanced geographical mapping (GIS). Students will also undertake a major project in a specific area of their choice.
