These materials are part of a collection of classroom-tested modules and courses developed by InTeGrate. The materials engage students in understanding the earth system as it intertwines with key societal issues. The collection is freely available and ready to be adapted by undergraduate educators across a range of courses including: general education or majors courses in Earth-focused disciplines such as geoscience or environmental science, social science, engineering, and other sciences, as well as courses for interdisciplinary programs.

Step 3: Summative Assessment Discussion and Analysis

Conclusions: Discussion and Completing the Assessment Analysis Worksheet

If you have finished both LCA sections, congratulations! You have just learned the basics of a common analysis tool for complex systems such as coupled natural-human food systems.

Taking stock: For discussion: here are some items you may want to discuss in your groups and with the class.

  1. Module 10.2 has been devoted to summarizing natural systems impacts of the food system. In this LCA, why did we focus on energy use and fossil fuel energy use in particular? What specific impact on natural systems, does fossil fuel use create that evokes sustainability concerns?
  2. Within the particular measurement parameter or metric from question one, which system created less impact on the earth system per unit of food produced (note that there might be other ways to measure the systems with other conclusions, see question 4)?
  3. Which system yielded more potatoes per area? Does this make a difference to the conclusions regarding energy use and its contribution to sustainability? (think about in which units we expressed the results of the analysis)
  4. What are other measures of sustainability that could be applied to the two systems? Think about the other natural systems components presented in sections II and III of the course and in module 10.1 and 10.2 (water, soil, etc.), or the concepts of social and economic/financial sustainability.
  5. What lessons from the smallholder system, could be applied to the industrial system, and vice-versa?

You will now complete an assignment based on the LCAs you have just conducted, to submit as the second part of your summative assessment, using a worksheet you will download below.

Submitting your Answers

Working in pairs of students, complete the worksheet short answer and paragraph responses, based on modules 10.1 and 10.2 and your responses on the Excel LCA worksheet you just completed. Log into the course management system to find the Summative Assessment 10.2 folder and upload both your excel for the pair of you and the short answer worksheet.

Grading and Rubric

This assessment is worth a total of 58 points. Note that all assessments are weighted equally across the course, so although this is a high point total this assessment is not worth more than other summative assessments. See rubric below for specifics.
