Sustainable agriculture students often learn about the food production process. A degree in this field can prepare graduates for jobs at research institutions or livestock companies. Besides learning about crops and farming, students may also take classes in statistics and microbiology.

Requirements for the PhD program often involve the student having already obtained a Master’s degree. Additionally, a thesis or dissertation primarily consisting of original academic research must be submitted. In some countries, this work may even need to be defended in front of a panel.
