Item New Curricula for Undergraduate Food-Systems Education: A Sustainable Agriculture Education Perspective(2014-12) Jordan, Nicolas; Grossman, J.; Lawrence, Patrick G.; Harmon, Alison H.; Dyer, William E.; Maxwell, Bruce D.; Cadieux, K.V.; Galt, Ryan; Rojas, A.; Byker Shanks, Carmen; Ahmed, Selena; Bass, Thomas; Kebreab, E.; Singh, V.; Michaels, T.; Tzenis, C.New undergraduate degree programs that address food systems have appeared at a number of North American universities in the past decade. These programs seek to complement established food- and agriculture-related courses of instruction with additional curricular elements that build students’ capacity to address complex food-systems issues (e.g., food sustainability, security, quality, equity and justice) in the course of their work in food-related professions. Here, we examine these emerging food-systems curricula, building on our collective experiences developing food-systems degree programs at University of British Columbia, Montana State University, University of California-Davis and the University of Minnesota. We present the conceptual framework that underlies our efforts, based on the premise that our degree programs should help students build “systemic” capacities that complement disciplinary training provided by various specialization “tracks.” Thus, we intend for our graduates to have a dual preparation, in both a particular specialization, and in overarching systemic capacities that enhance their ability to address complex food-system issues. We assess our current curricula in light of our framework, and outline high-priority pathways for further development of these curricula.Item Bromus tectorum Response to Fire Varies with Climate Conditions(2014-09) Taylor, Kimberley T.; Brummer, Tyler J.; Rew, Lisa J.; Maxwell, Bruce D.The invasive annual grass Bromus tectorum (cheatgrass) forms a positive feedback with fire in some areas of western North America’s sagebrush biome by increasing fire frequency and size, which then increases B. tectorum abundance post-fire and dramatically alters ecosystem structure and processes. However, this positive response to fire is not consistent across the sagebrush steppe. Here, we ask whether different climate conditions across the sagebrush biome can explain B. tectorum’s variable response to fire. We found that climate variables differed significantly between 18 sites where B. tectorum does and does not respond positively to fire. A positive response was most likely in areas with higher annual temperatures and lower summer precipitation. We then chose a climatically intermediate site, with intact sage-brush vegetation, to evaluate whether a positive feedback had formed between B. tectorum and fire. A chronosequence of recent fires (1–15 years) at the site created a natural replicated experiment to assess abundance of B. tectorum and native plants. B. tectorum cover did not differ between burned and unburned plots but native grass cover was higher in recently burned plots. Therefore, we found no evidence for a positive feedback between B. tectorum and fire at the study site. Our results suggest that formation of a positive B. tectorum-fire feedback depends on climate; however, other drivers such as disturbance and native plant cover are likely to further influence local responses of B. tectorum. The dependence of B. tectorum’s response to fire on climate suggests that climate change may expand B. tectorum’s role as a transformative invasive species within the sage-brush biome.
