The Department of Environmental Sciences offers B.A. and B.S. degrees in Environmental Sciences. Students are encouraged to concentrate their studies in one of five specialization areas: Soil Sciences, Hydrologic Sciences, Atmospheric Sciences, Environmental Toxicology, and Environmental Management.

Modern human activities related to natural resource development, agriculture, urbanization, industry, and transportation are placing unprecedented pressure on the earth’s life support systems. Changes taking place in atmospheric physics and chemistry, land cover, freshwater and marine resources, and chemical cycling threaten the ability of human society to sustainably meet current and future needs. Science-based solutions are needed to sustainably manage our natural resources and improve public health. To help meet these challenges, our program emphasizes training for students in the biological, chemical, and physical aspects of environmental sciences and health, centered on the major environmental media of air, soil, water, and the biosphere. The structure of the Environmental Sciences curriculum provides a broad scope of instruction that enables students to explore various disciplines and professions focused on solving environmental problems. All students majoring in Environmental Sciences must complete a set of “core requirements” consisting of courses that provide a basic understanding of the physical, biological, and social sciences and their application to the analysis of environmental processes and management issues. In addition to the core requirements, students must complete 8 units of lower-division and 20 units of upper- division elective courses.

Students have the option to select their electives from different specialization areas or to focus their training in one of the five specialization areas based on their own educational and career objectives. The specialization areas of Soil Sciences, Hydrologic Sciences, or Atmospheric Sciences are suitable for students wishing to maintain a broad range of choices in technically-oriented environmental professions such as pollution control, hazardous materials management, public health, natural resource management, environmental monitoring, and impact analysis. These options also provide the necessary background for graduate study in soil science, water resources, or atmospheric sciences as well as interdisciplinary areas such as ecosystem science and forestry. The Environmental Toxicology specialization area emphasizes the chemistry and biochemistry of toxic substances in the environment, preparing students for careers dealing with the control of contaminants in various environmental media as well as related fields such as public health and industrial hygiene. The Environmental Management specialization area is oriented for the social context of environmental sciences and prepares students for careers dealing with environmental regulation, land-use planning, environmental impact analysis, and administration of environmental protection programs.

Environmental Internship Program The Environmental Internship Program offers students opportunities to work with govern- ment agencies, private firms, and nonprofit or- ganizations involved in environmental affairs. As excursions into professional life, internships provide “hands-on” experience in applying the principles presented in courses. Beyond the highly specialized training associated with on-the-job activities, students can gain insights into their aptitudes, aspirations and work habits that enable them to clarify their academic and career objectives. Professional acquaintances established during internships can continue to serve as important contacts for students after the internship is completed.

Although most internships are part-time (12–15 hours per week) positions in the Riverside area, organizations that host student interns are located throughout the United States and in Washington, D.C. Students working as interns may receive stipends, hourly wages, or serve as volunteers, depending upon the specific appointment. Up to 16 units of credit toward the bachelor’s degree may be earned by developing an academic component of the internship in consultation with a faculty super- visor and enrolling in ENSC 198-I.

Undergraduate Research Students interested in enhancing the status of knowledge about environmental processes or seeking new solutions to environmental problems may gain training and experience as part-time employees in the department’s research laboratories and other research facilities, such as the U.S. Salinity Laboratory, located on campus, and the USDA Pacific Southwest Research Station, located on Canyon Crest Drive. Those wishing to conduct their own research under faculty supervision may earn academic credit by enrolling in ENSC 197. Expenses for both laboratory and field experiments are eligible for funding by the campus mini-grant program which supports undergraduate research and creative activity.

California Teach-Science/Mathematics Initiative (CalTeach-SMI) California Teach-Science Mathematics Initiative (CalTeach-SMI) has a goal of addressing the critical need of highly qualified K-12 science and mathematics teachers in California. With an economy increasingly reliant on science, technology, engineering, and mathematics (STEM) and the anticipated large scale retirement of qualified teachers, this is an essential time to explore and prepare for a career in teaching science or mathematics.

CalTeach-SMI at UCR offers undergraduate students opportunities to explore STEM teaching as a career option. Through CalTeach- SMI, students receive advising and mentoring to prepare for entrance into an intern teaching credential program while diligently coordinating with academic advisors to ensure completion of STEM degree requirements. The CalTeach-SMI Resource Center provides future STEM teachers opportunities to promote planning and professional development towards a science/ mathematics education career.

For more information about the CalTeach-SMI program, please visit smi.ucr.edu, the Resource Center at 1114 Pierce Hall, or on Facebook at facebook.com/ScienceMathInitiativeAtUcr.
