Global Change - Online Dialogue

Spring 2009

Discussion goal

The goal of this exercise is to generate discussion among assigned student groups on the issue posed below. Discussion is online and occurs through discussion groups linked in WebCT.

Discussion question

Agriculture can be sensitive to climate change, but at the same time, agricultural practices can contribute to climate change, such as through burning fossil fuels to produce and transport agricultural products and through the clearing of land. Consider reducing agriculture's "carbon footprint". In what ways could that be done and what impacts would that have on agriculture's output (i.e., yields) and costs (economic viability)?

Discussion access

To get to your discussion group and participate, login to WebCT and then follow the link to our class. When there, click on the "Discussions" tab on the left column. This will automatically take you to the discussions for your group. Select "Agriculture and Climate Change" to go a web page where you can read contributions by others and add your own.

Grading guidelines

  • 2 points for just posting a comment
  • 2 points for backing the comment with a reference to a scholarly article
  • 2 points for posing an additional substantive question
  • 2 points for responding substantively to another post in the group beyond your first posting (e.g., this could be additional support for the other post, or support for a different conclusion) The second posting has to respond to something already there from another member of the group.
  • 2 points for citing scholarly material in the second posting

    10 points maximum, but you are welcome to make additional postings

    You must complete your work by the last day of classes at midnight to get full credit.

    Sources for finding information

  • IPCC reports
  • Other links at the bottom of the class web page
  • Google Scholar
  • (Science Citation Index) [ISI Web of Knowledge; available from iastate.edu computers]

    NOTE: Scholarly article = journal article, book or other major peer-reviewed publications for a discipline. It is not a blog or other opinion piece, nor Wikipedia or the like. It also does not include newspaper or magazine articles. Rather, you should cite primary sources, which can be found through the lists above.

    Plagiarism is unacceptable! You must document the source of any piece of information that is not yours in the dialogue. This of course is necessary also in order to get credit for referencing a scholarly article, as requested in the "Grading guidelines". If you choose to copy a phrase directly from a source, you must place it in quotes and cite its source. However, it is recommended that you employ your own words to describe a set of data or to explain a concept. The sources of data and each assertion that is not yours (including interpretations and point of views) must be acknowledged by citing the source within your dialogue entry. Because you are not writing a formal paper in the dialogue, please treat citations a little differently. Citations in this case should be in parentheses and give the author(s) or "Author et al.", followed by the year and the source of the information (e.g., journal name and page numbers).
