1. Sustainable Agriculture Class 3

1.1. Overarching exercise and presentations

  • Overarching exercise: Application of scientific method to problem solving: how to translate the problem into something that is testable¬† - Elena Naumova

  • Followed by discussion on formulating hypothesis

  • Presentation on the basics of dairy farming systems - George Saperstein - followed by discussion

  • Short presentation on Life Cycle Assessment - Michael Reed

1.2. Class Activity

  • Revisit "problem" in terms of hypothesis discussion and finalize

  • Begin to work with VUE

  • Research feedback

  • Identify student disciplinary focus

1.2.1. Charge:

Groups now to pursue research on human, animal, and environmental health impacts of dairy farming, comparing organic and conventional methods (can also site "sustainable" methods, but must provide contextual definition - we will collect and discuss these in an upcoming session) ; groups should organize themselves and develop a plan for conducting research and coordinating their own communication and eventual reporting to the larger group.

Farming perspective: outline the process of organic dairy vs. conventional to form the framework of our LCA/VUE model and research the health awareness and concerns of the farming and policy community

Animal health perspective: collect information on animal health concerns in dairy farming, also document interaction with wildlife and issues related to wildlife disease transmission (both direction) and also consider other domestic animal health concerns on a dairy farm

Human health perspective: collect information on human health concerns in dairy farming with special emphasis on the farmer, their family and community. Less emphasis on nutrition regarding dairy products, etc. (this is a bit tangential to the theme)

Environmental health perspective: both engineers perspective, collect information on impacts of dairy farming on the environment - use engineering perspective to document how these things are assessed, what information is available (or not), and various mitigating methodologies that can be employed to control the impact
