课程题目：Sustainable Biosystems Engineering
Sustainability may not be a tangible concept to many people even today; however, the deterioration of environment and the depletion of natural resources have drawn increasing attention and prominence since late 20th century. The uncontrolled global population growth as well as the inequality of wealth distribution has increased pressure on air, water, arable land, and raw materials. This course will present the basic concept of sustainability and discuss the contemporary issues we are facing today in the areas of energy and other natural resources. Process and methodologies associated with measuring, assessing, and designing sustainable systems in water, energy and food will be discussed in detail, with emphasis on using life cycle assessment (LCA) for inventory and impact analyses. Also included in discussion are macroethics, green materials, biodiversity index calculation, and release of hazardous materials to the environment associated with the LCA process. Students will learn application of the LCA methods through in-class exercises and projects. Since agriculture is the industry that occupies the largest land area among all industries and consumes 70% of the world fresh water supply every year, how to evaluate the role that agriculture plays in the overarching goal of maintaining worldwide sustainability will also be discussed at length in this course.
