Degree Offered: BS in global environmental science

The Academic Program

Global environmental science is a holistic, scientific approach to the study of the Earth system and its physical, chemical, biological, and human processes. This academic program is designed to educate leaders and citizenry to become wise stewards of our planet. Global environmental science focuses on the global reservoirs of hydrosphere (water, primarily oceans), biosphere (life and organic matter), atmosphere (air), lithosphere (land, sediments, and rocks), and cryosphere (ice); their interfaces; and the processes acting upon and within this interactive system, including human activities. In the course of their scientific studies, global environmental science students are able to investigate natural as well as economic, policy, and social systems and their response and interaction with the Earth system. Global environmental science has important ties to the more classical sciences of geology and geophysics, meteorology and climatology, oceanography, and ecology as well as to the social sciences. Thus, the scope of global environmental science is extremely broad. This breadth is reflected in the interdisciplinary nature of the faculty, which is primarily drawn from numerous departments and research institutions within the School of Ocean and Earth Science and Technology.

Global environmental science has much to offer the student who is interested in the environment and the effect of humans on the environment. The skills developed in global environmental science can be brought to bear on local, regional, and global environmental issues. Many of the critical environmental problems confronting humankind involve large-scale processes and interactions among the atmosphere, oceans, biosphere, cryosphere, shallow lithosphere, and people. Some of the problems derive from natural causes; others are a result of human activities. Some of the issues that global environmental science students deal with are: climatic changes from anthropogenic inputs to the atmosphere of CO2 and other greenhouse gases; human interventions and disruptions in the biogeochemical cycles of carbon, nitrogen, phosphorus, sulfur, trace metals, and other substances; emissions of nitrogen and sulfur oxide gases and volatile organic compounds to the atmosphere and the issues of acid deposition and photochemical smog; depletion of the stratospheric ozone layer and associated increase in the flux of ultraviolet radiation to Earth’s surface; increasing rates of tropical deforestation and other large-scale destruction of habitat, with potential effects on climate and the hydrologic cycle; disappearance of biotic diversity through explosive rates of species extinction; global consequences of the distribution and application of potentially toxic chemicals in the environment and biotechnology; interannual and interdecadal climate variability, e.g., El Nino/Southern Oscillation; eutrophication; water and air quality; exploitation of natural resources with consequent problems of waste disposal; earthquakes, tsunamis, and other natural hazards and prediction; and waste disposal: municipal, toxic chemical, and radioactive. In all cases, the student is encouraged to understand and appreciate the social, economic, and ultimately the policy decisions associated with these and other environmental issues.

Specifically with respect to learning objectives, the students develop competency in understanding how the physical, biological, and chemical worlds are interconnected in the Earth system. They obtain skills in basic mathematics, chemistry, physics, and biology that enable them to deal with courses in the derivative geological, oceanographic, and atmospheric sciences at a level higher than that of qualitative description. In turn, these skills enable the students to learn the subject matter of global environmental science within a rigorous context. The students develop an awareness of the complexity of the Earth system and how it has changed during geologic time and how human activities have modified the system and led to a number of local, regional, and global environmental issues. They become competent in using computers and dealing with environmental databases and with more standard sources of information in the field. They are exposed to experimental, observational, and theoretical methodologies of research and complete an environmentally focused senior research thesis in environmental study using one or more of these methodologies. Project field work is encouraged for the senior thesis and, depending on the topic chosen by the student, can be carried out at the Hawai‘i Institute of Marine Biology’s Coconut Island facility, E. W. Pauley Laboratory, associated He‘eia ahupua‘a, Ka Papa Lo‘i O Kanewai, or elsewhere.

The ultimate objective of the global environmental science program is to produce a student informed in the environmental sciences at a rigorous level who is able to go on to graduate or professional school; enter the work force in environmental science positions in industry, business, or government; enter or return to teaching with knowledge of how the Earth system works; or enter the work force in another field as an educated person with the knowledge required to become a wise environmental steward of the planet.

BS in Global Environmental Science

University Core and Graduation Requirements

Of the 31 credits of General Education Core Requirements, 10 are in math and science and are fulfilled through the GES degree. Graduation Requirements include 8 Focus courses, 7 of which can currently be taken through the GES program requirements [Contemporary Ethical Issues (OCN 310), Oral Communications (OCN 490), and 4 Writing Intensive courses (BIOL 171L, OCN 310, 320, 399, 401, and 499)].

Global Environmental Science Requirements

Aside from General Education Core and Graduation requirements, the global environmental science program has core requirements of two basic types: basic sciences and derivative sciences. The former provides the foundation to understand and appreciate the latter in the context of basic skills and mathematics, biology, chemistry, and physics. Both global environmental science core requirements provide the necessary cognitive skills to deal with the higher academic level courses within the global environmental science curriculum. These include 7 required foundation courses in global environmental science and a minimum of 4 coupled systems courses. It is within this latter category of course work that the formal course program will be tailored to the individual student’s needs. For example, we anticipate that most students will follow closely a natural science track of study, perhaps concentrating on the terrestrial, marine, or atmospheric environment. However, because of the human dimensions issues involved in the subject matter of environmental change, some students may wish to expand their academic program into the social sciences that bear on the issues of global change.

A minimum grade of C must be obtained in all GES required courses.

In addition to students being able to choose their own coupled systems courses to customize their degree per their interests and goals, the global environmental science program also has four tracks (with defined coupled system courses) in the cross-disciplinary environmental science areas of (1) environmental planning, (2) environmental health, (3) sustainable tourism, and (4) sustainability science. For each of these tracks, the collaborating department and their faculty have agreed to support the major required research thesis project so that global environmental science students are able to focus both their curricular and research experience in track’s subject material.

  1. Environmental Planning (cross-disciplinary with Department of Urban and Regional Planning): Global environmental problems like human-induced climate change challenge local strategies to manage natural resources, protect sensitive species’ habitats, and ensure the long-term health of ecosystems. With over fifty-percent of the world’s population now living in urban areas and consuming most of the earth’s resources, the way we plan, design, and regulate our cities exacerbates local conditions. At the same time, urban areas are also important locations for solutions. Environmental planners adopt solutions-oriented approaches to address environmental problems, such as supporting local food production, building disaster risk reduction, deploying clean sources of energy, conserving biodiversity and natural habitats, managing urban waste, adapting to sea-level rise, and preserving freshwater resources. Planning as a discipline has a long tradition in problem solving across different scales from neighborhoods to entire regions with extensive community involvement. Graduates will be uniquely positioned for careers as environmental planners, specialists, and consultants employed by government agencies or private firms required to review planning permits, develop master plans, prepare environmental impact studies, or develop mitigation strategies to minimize development impacts.
  2. Environmental Health Sciences (cross-disciplinary with Office of Public Health Studies): This track enables a student in the Global Environmental Sciences Program to concentrate his/her academic studies in areas of significant importance in the relationship between environmental issues and public health. The inter-relationship between the environment and its impact on human health is vast and constantly changing. Issues such as food security, emerging zoonotic diseases, water scarcity, air and water pollution, over population, waste disposal, pesticide use, depletion of resources on land and in the sea are just a few of the pressing environmental issues that affect the health and well-being of millions of people worldwide. In this track students will gain the basic scientific knowledge necessary to understand the underlying science of the environment while simultaneously being exposed to public health principles that are essential for establishing cause and effect relationships between environmental conditions and human health, as well as understanding the compromises that sometimes must be made to accommodate economic, health, and environmental preservation goals. Graduates of this track will be uniquely positioned for careers in the environmental health field ranging from laboratory workers to regulatory policy and enforcement officers with environmental agencies.
  3. Sustainable Tourism (cross-disciplinary with the School of Travel Industry Management): The relationship between tourism and the natural environment is intimate and complex. The desire for contact with nature drives enormous volumes of tourism, yielding not only tourist spending and associated jobs and tax revenues, but also pollution, waste, and overdevelopment resulting from the transportation of masses of people and the construction and operation of tourism-related facilities. Indeed, such pollution, waste, and overdevelopment diminish the quality of the very environments that impel nature-based tourism to begin with. In addition, issues such as food security, water scarcity, overpopulation, urban sprawl, pesticide use, global warming, rising sea levels, and depletion of resources on land and in the sea are just a few of the pressing environmental issues that affect the attractiveness, competitiveness, and sustainability of destinations throughout the world. Graduates will be uniquely positioned for careers as planners, specialists, and consultants employed by government agencies required to prepare environmental impact studies and/or tourism plans, consulting firms that prepare such studies and/or plans for government agencies, and nonprofit organizations that operate tourism “ecocertification” programs that provide tourism-related businesses with credentials of their “greenness.”
  4. Sustainability Science: Sustainability Science probes interactions between global, social, and human systems, the complex mechanisms that lead to degradation of these systems, and concomitant risks to human well-being. As Sustainability Science has emerged in the 21st century as a new academic discipline, it brings together scholarship and practice, global and local perspectives, and disciplines across the natural and social sciences, engineering, and medicine–facilitating the design, implementation, and evaluation of practical interventions that promote sustainability in particular places and contexts. The GES graduate from the sustainability track is prepared for opportunities in all fields that would hire environmental scientists, and to be especially competitive for those opportunities that target the design, analysis, implementation, maintenance, and/or monitoring of processes or systems that target increased sustainability.
