The Department of Environmental Science provides instruction in environmental science, environmental management, environmental studies, the Earth sciences, and science, technology and society.  It also engages in studies that aim to understand how nature works, discover knowledge that can be used to formulate sound environmental policies, and develop approaches and technologies that can address environmental problems.  It prepares future environmental scientists and managers for careers in research, academe, government, private sector, and civic and non-government organizations.
The department has the following objectives:
  1. equip students with adequate theoretical knowledge and practical skills that will enable them to manage and investigate the environment, and to find solutions to global and local environmental problems;
  2. inculcate among students culture of excellence, civic consciousness, integrity, and teamwork;
  3. engage in research on various environmental topics to generate knowledge that can be used to develop technologies, strategies, and policies for environmental protection, and;
  4. to provide consultancy, extension, and training services to the communities, government agencies, industry, and non-government organizations.
