Purpose Statement
The Environmental Science program at NAU constructs an interdisciplinary base of knowledge and skills to explore and develop real-world solutions to environmental problems.
Our program provides a firm grounding in the natural and social sciences to ensure all students understand how chemical, physical and biological processes maintain life, and the complex relationships among humans and the environment. Students work together and individually in the classroom, field and laboratory to practice applying the scientific method to address environmental problems and explore creative solutions that apply cutting-edge technologies.
The broad range of emphases available within our program allows students to delve deeper into a specific knowledge base, then work individually and often together in Environmental Science courses to solve problems by applying the perspectives and knowledge they developed in their emphasis with students from other emphasis areas. To culminate the learning in the program, students develop an individually designed research project or internship addressing an environmental issue of importance to them, which in turn, is expected to further prepare students for a range of professional or graduate opportunities.
Student Learning Outcomes
- Examine how the Earths’ natural systems interact and change over time and the effects of anthropogenic resource use and management on these systems, including feedbacks and impacts to ecosystem services, through the use of basic ecological experimental design and data collection.
- Apply the scientific method and critical thinking to address environmental problems, integrate historical perspectives, and explore solutions across a range of spatial-temporal scales.
- Use statistics and models to analyze environmental data with the following goals: quantitatively describe processes, assess uncertainties, test hypotheses, measure trends; reveal spatial and temporal patterns, explore relations among variables, and create sustainable solutions to environmental problems.
- Analyze topographic maps and remote sensing images using GIS tools to identify the geologic framework, ecological community types, and human environments and make recommendations to resource managers.
- Apply information about basic reservoirs and fluxes of the carbon, nitrogen, phosphorus, sulfur, rock, and water cycles to develop recommendations for resource management that would reduce human impacts on climate change.
- Use basic water, air and soil sampling methods to explore various management methods to improve water, air, and soil quality.
- Identify and effectively communicate environmental issues and sustainable solutions using both natural science and social science principles.
- Investigate the effects of resource management within linked natural and social systems and develop potential ecosystem service solutions that resolve imbalances.
