To educate future leaders at the nexus of agriculture, food, and environmental science and policy, and empower them by providing rigorous training, an ethic of social change, and an intellectual community generating visions and models of alternative systems.

The Agriculture, Food and Environment (AFE) program within the Friedman School of Nutrition Science and Policy fuses the disciplines of nutrition, agricultural science, environmental studies, and public policy. We offer M.S., Ph.D. and combined degree programs, diverse community service and internship placements, and opportunities to participate in research on sustainable agriculture, local food systems, and consumer behavior related to food and the environment. Students in the AFE degree program learn to evaluate the ecological, political, economic and social aspects of food production and distribution. Faculty members come from the Friedman School of Nutrition Science and Policy, the Graduate School of Arts and Sciences, and the Fletcher School of Law and Diplomacy.


Master of Science

The curriculum includes core courses in nutrition science, food and environmental policy, and research skills. Each student completes a specialization (three to five courses), a field internship, and a self-designed directed study project. A total of 16 one-credit courses are required for the M.S. degree. Learning objectives:

  • To develop a breadth of understanding of agricultural science and policy issues related to soil, energy, air, water, plant breeding, plant nutrients, livestock production, pest management, and forestry
  • To develop in-depth expertise on one area of AFE through specialized class work (e.g., water resources policy, local food systems, animal welfare, etc.)
  • To develop sophisticated knowledge of the policymaking process
  • To understand historical and current aspects of U.S. agricultural production, policy initiatives, and structures
  • To develop competency in statistical methods and data analysis
  • To develop basic knowledge of nutrition science
  • To become a critical thinker, with advanced research, analysis, and writing skills

Doctor of Philosophy

Students enrolled in the doctoral program must have completed courses equivalent to the AFE master's degree at the Friedman School of Nutrition Science and Policy or elsewhere. Students in the doctoral program must pass a written and oral qualifying examination, and then complete and formally defend a doctoral dissertation based on original research. Learning objectives:

  • To become proficient in study design, hypothesis development, and statistical analysis
  • To become proficient in presentation (oral and written) and publication of research findings
  • To command a sophisticated understanding of relationships connecting agriculture, food and the environment
  • To become conversant in the breadth of scientific and policy knowledge related to agriculture, food, and environmental issues

Combined Degree Programs: MALD, MPH, UEP, WSSS

Students enrolled in combined degree programs complete all the requirements for both degrees, but by counting selected courses towards both programs, they reduce the total time required for completion. Students must be admitted independently to each program. Our combined degree programs allow formal recognition of students emphasizing these additional areas of study, greater depth of professional preparation, and opportunities to make connections with students and faculty members in other related programs.

  • A combined degree program with the Fletcher School of Law and Diplomacy results in both the Master of Science in Nutrition and a Master of Arts in Law and Diplomacy (MALD).
  • A combined degree program with Tufts University's School of Medicine leads to the Master of Science in Nutrition and the Master of Public Health (MPH).
  • A combined degree program with Tufts University's Department of Urban and Environmental Policy and Planning results in both the Master of Science in Nutrition and a Master of Arts in Urban and Environmental Policy and Planning.

Students may also earn a professional certificate in the Water: Systems, Science and Society (WSSS) program—an exciting new offering at Tufts University, providing multidisciplinary perspectives and tools to manage water-related problems. Students must be accepted by and obtain their graduate degrees from an existing school or department in order to be eligible for the WSSS certification.


Students come to the AFE Program to help build a more desirable food production and distribution system, making agriculture and food systems more supportive of the natural environment and the society they serve. Students apply to AFE from varied academic and professional backgrounds in areas such as agriculture, biology, nutrition or health and environmental studies, as well as political science, history, economics and business or the liberal arts. Most students enter the program with applicable professional and volunteer experience which contributes to classroom discussion and community life.


To be eligible, applicants must have completed a Bachelor's degree, and have demonstrated their commitment and ability to succeed in the AFE program through previous coursework, including at least one course in general biology or chemistry, plus employment and volunteer experience as well as the GRE exam.  For students who seek to refresh their verbal and quantitative skills, self-study materials and sample questions are available from the Educational Testing Service. Students whose native language is not English must take and pass the TOEFL exam.


Note: Current students should refer to the degree requirement worksheet associated with their year of entry for the most accurate course requirements.

Program Core

These are the required courses for the AFE program:

  • Fundamentals of U.S. Agriculture  (NUTR 215)
  • Agricultural Science and Policy I (NUTR 233)
  • Agricultural Science and Policy II (NUTR 333)
  • Economics of Agriculture and the Environment (NUTR 341)


One of the most positive aspects of AFE is the flexibility for each student to mold a specialization around the academic and professional interests that motivate our

individual visions of sustainable food systems.

—Nyssa Schloyer (AFE '06)

Each AFE student chooses to specialize in a topic area related to future employment. Examples of topic areas include agricultural development, community development and organizing, food risk assessment, and resource economics. The specialization requires a minimum of three courses. The

professional skills course and directed study may be among the three specialization courses.

Participation in the Water: Systems, Science and Society (WSSS) program may serve as an approved specialization, with the added benefit of a professional certification.
