Agriculture in the United States is currently facing major challenges. Amid
abundant yields, many family farmers are going bankrupt. Fertilizers that were
once cheap have become more expensive. Pesticides that were once effective are
failing to overcome pests that have developed resistance. Soil erosion threatens
long term productivity in many areas. Public concern over contamination of water
and food by agricultural chemicals is increasing.
In developing countries, soil erosion, deforestation, desertification, loss
of genetic diversity, pesticide poisoning, poverty, malnutrition, and hunger
remain major problems, despite the efforts of numerous agricultural development
To address these challenges, the University of Maine, through various degree
programs, has offered a comprehensive concentration in Sustainable Agriculture
since 1988, emphasizing:
- increasing farm economic resilience and profitability by decreasing the
costs of crop and livestock production;
- building soil tilth and fertility through efficient use of crop rotations,
multiple cropping systems, animal manures, and recycled waste products;
- protecting water quality, worker health, and food safety;
- managing pests with multi-faceted, ecologically sound strategies that have
minimal reliance on synthetic, broad-spectrum pesticides;
- creating strong rural communities that can be sustained through years of
fluctuating crop prices and unpredictable weather.
Although program activities are focused in Maine, the agroecological principles
that we study and apply are relevant throughout the world. Graduate students
in the program are from all parts of the United States as well as Canada, Europe,
Latin America, Asia, and Africa. No formal international component to the program
exists, but faculty and students have worked in Brazil, Burkina Faso, Mexico,
Nicaragua, and Kenya.
Graduate students studying Sustainable Agriculture at the University of Maine
can earn one of the following degrees, depending on their specific interests:
Doctor of Philosophy
Ecology and Environmental Sciences
Master of Science
Botany and Plant Pathology
Ecology and Environmental Sciences
Plant, Soil and Environmental Sciences
Resource Economics and Policy
Course work is drawn from the offerings of many departments. Research activities
are conducted at the University’s Rogers Farm, near Orono, and at the University’s
Aroostook Farm, in northern Maine’s potato production region. A large-scale
interdisciplinary potato ecosystem study is underway at the Aroostook Farm.
The Rogers Farm is used for work with a variety of field and vegetable crops.
Several projects are being conducted on commercial farms.
For more information about graduate work in Sustainable Agriculture at the
University of Maine and the availability of financial assistance, prospective
students should contact faculty members who might supervise their studies. General
