There is substantial evidence linking agricultural production and environmental degradation. Growing public awareness of various environmental issues such as global warming, toxic residues in food, and biodiversity loss has brought about a call for sustainable food production practices. Against a backdrop of an increasing world population, a key issue in future food supply is that, even in well-endowed areas, there are limits to the impact that the natural and human systems of the environment can tolerate. Thus, daily food choices by large segments of the population can ultimately result in an effect on the environment and may have public health consequences. Moreover, it has been suggested that global climate change will alter agricultural productivity across wide geographic areas, decreasing food security and resulting in changes in population food patterns.

Doctoral Programs

The first Environmental Nutrition doctorate project was completed in 2006 on the natural resource requirements of dietary choices in California. There are many Environmental Nutrition topics that could be covered through doctoral studies. The program could incorporate natural and environmental sciences, nutrition and/or epidemiology. Students could study for a DrPH or a PhD and be based in the School of Public Health and/or the Department of Earth and Biological Sciences. If you are interested, please contact Dr. Sujatha Rajaram.

Postdoctoral Fellowship

The environmental nutrition postdoctoral fellowship began in 2008. Activities have included data collection on the environmental impacts of foods, analysis of dietary patterns and writing journal articles. The award is for one year, with renewal for a second year upon successful completion of first year goals, and carries a stipend of $49,920 per year with an additional $3,000 per year for research expenses. The focus of this Fellowship Program is the interrelation among food, environment and public health. It is specifically designed to investigate the impact of food production, processing, distribution and consumption on the environment and public health. This position will focus on research and writing. A schedule of research topics and activities will be designed in line with the Environmental Nutrition agenda.


Candidates interested in applying to the fellowship program must have a doctoral degree in a field related to the area of interest, such as environmental health, nutrition, epidemiology, or ecology. Candidates must also have an interest in inter- and trans-disciplinary research and, ideally, a strong background or training experience in public health or in two or more of the disciplines listed above. A working knowledge of vegetarian nutrition will be helpful. Candidates should possess proven quantitative skills as well as professional English writing skills. International applicants are welcome to apply. US citizenship is not required.
