2026-2028 Catalog

Offered at: San Luis Obispo Campus

The BS in Environmental Earth and Soil Sciences provides an interdisciplinary foundation for understanding how land, water, and atmospheric resources contribute to sustainable natural resource management. The program emphasizes a wide range of disciplines in environmental  and natural resources and in the cultures that use and modify them. The core of the Environmental Earth and Soil Sciences curriculum is composed of earth science, environmental science, soil science, and geology and is strengthened by a diverse array of related specialties, which include: environmental science, GIS and data science, water science, and soil resource management. 

The Environmental Earth and Soil Sciences major provides detailed and thorough training in the natural and cultural processes that govern the relationship between humans and their environments. The program also furnishes students with the marketable expertise to assess, manage, repair, and improve this fragile relationship while acquiring a well-rounded education in the natural sciences. In addition, majors can meet the educational requirements for professional certification in a number of areas (e.g. Geologist in Training, erosion and sediment control, hydrology, soil conservation, soil science) and find their training ideal for graduate school preparation in a number of related disciplines. 

Due to the multidisciplinary nature of the Environmental Earth and Soil Sciences major, students have access to diverse faculty and laboratories in several colleges on campus. California's Central Coast offers a diverse environmental and cultural setting for real-world training and experiences in environmental sciences. 

Environmental Earth and Soil Sciences graduates are employed in careers in environmental consulting, carbon farming, natural resource inventory and assessment, environmental mitigation and clean-up, and environmental planning.  Environmental Earth and Soil Sciences graduates possess an interdisciplinary understanding of how water, air, and soil interact, as well as an ability to assess how the management of these critical natural resources impacts global environmental change. 

Concentrations

Geology

Offered at: San Luis Obispo Campus

Students learn the fundamentals of a broad variety of geologic subdisciplines, including mineralogy, petrology, seismology, stratigraphy, geochemistry, geomorphology and structural geology. Each of these fundamental subdisciplines are supported by curriculum that emphasizes methods of data collection, interpretation and professional communication of results. Upon completion of this concentration, students are able to critically evaluate geologic reports within the context of our evolving societal needs, and are prepared to pursue post graduate degrees in the geosciences and/or careers in the geotechnical industry. Completion of this concentration coupled with a BS degree in Environmental Earth and Soil Sciences qualifies a graduate to take the Geologist in Training examination (GIT) and become certified as a GIT, which can eventually lead to licensure as a Professional Geologist (PG).

Program Learning Objectives

  1. Demonstrate critical thinking and problem solving skills.
  2. Communicate environmental science principles and research findings effectively and professionally to diverse audiences.
  3. Integrate and apply technical knowledge in the following areas: geology and climate; soils and water; geography and geospatial technology; resource management.
  4. Demonstrate proficiency in quantitative skills and information management specific to environmental earth and soil science.
  5. Demonstrate an understanding of their professional and ethical responsibilities, including respect for diversity.
  6. Implement life-long learning habits by exposing students to the discovery process of applied research and demonstration projects conducted by the environmental science faculty.

Degree Requirements and Curriculum
