All living things including human being need to eat to live. To get food stably, our ancestor started farming and that has led our culture development. However, this “development” has become the cause of our modern problems related to food supply chain. Urban citizens are tending to ignorance where their food come from, and not only about the food itself but also people are forgetting the farmlands are playing important role to maintain the environment and social infrastructure through agriculture. This course provides chance to think about the fundamental meaning of agriculture as an essential element of sustainable development with five key elements: environment, education, tourism, welfare&well-being, energy. Two persons are responsible for this course who are both farmers, one in Fujisawa and one in Kumamoto, and are graduate of SFC. Not only learning and rethinking about agriculture but also we will discuss and think idea for future agriculture and environment.
