This Master's thesis examines political activism centered at the Gill Tract Community Farm (GTCF) in Berkeley, California. The Gill Tract is roughly 14-acres of University of California, Berkeley (UCB) research land at the boundary of Berkeley and Albany, in the San Francisco Bay Area (SFBA). The GTCF is a community-led agro-ecological farm which emerged out of a protracted land occupation in 2012, and situates itself as a site of opposition to capitalism and colonialism. In 2020, I conducted 17 semi-structured interviews with community farmers and university administrators about the relationship between UCB and the GTCF. Drawing on the interviews, written media, and auto-ethnographic reflections of my own time living in the SFBA and volunteering at the GTCF, I examine three distinct questions. 1) I discuss how the theory of boundary objects helps to understand why the Gill Tract was a site of contestation in 2012, and how the theory of boundary objects can be deepened by viewing them not only as sites of cross-disciplinary collaboration, but also dispute. 2) I explore the uneven ways in which the university and the community farm are legible to each other and are changing each other, read through social scientists engaging with activist movements. 3) I engage in a partially auto-ethnographic reflection on the political potential of the GTCF, using anthropological work on narrative and the alter-globalization movement to frame activism at the community farm. This thesis contributes to a deeper understanding of boundary objects, as well as understandings of the potential for local activist movements to effect political change, both locally and within global activist networks.

Canada has some of the highest rates of pediatric Inflammatory Bowel Diseases (IBD), including Crohn’s disease (CD) and ulcerative colitis (UC), in the world. Environmental factors are known to be important for disease development but are not well understood. This study used two forms of analysis to examine the epidemiology and potential causes of IBD diagnosed before age 17 in the Canadian province of British Columbia from 2001 to 2016. A spatial cluster detection methodology was used to locate disease clusters of high and low incidence rates, the presence of which would highlight potential environmental risk and protective factors. Logistic regression models of case-control data were used to measure the relationship between IBD diagnosis and NO₂ air pollution, density of residential and neighborhood vegetation greenness (green spaces), vitamin D adjusted ultraviolet solar radiation, area South Asian and Jewish ethnicity, area self-identification as Aboriginal, and area social and material deprivation. The spatial distributions of IBD, CD, and UC were significantly clustered, with consistent IBD hot spots identified near the main urban centre of the province and cold spots identified in rural areas of south-eastern British Columbia. CD and UC had similar and different hot and cold spots, suggesting both shared and distinct environmental determinants. Most measured associations between variables of interest and IBD were moderate or small; as IBD is a multifactorial disease, these variables may still have a population-level effect on disease risk or interact with other risk factors and should be studied further. NO₂ air pollution was a significant risk factor for UC. Area South Asian ethnicity was only a significant risk factor in the univariate analysis, though a small and similar effect was observed in the multivariate analysis which included social and material deprivation. Ultraviolet vitamin D exposure was a protective factor for UC and IBD, especially in winter months. Area Aboriginal identity and area material deprivation (areas with lower socioeconomic status) were significant protective factors for CD, though Aboriginal identity was not significant in a multivariate analysis that included social and material deprivation. No reliable relationship was observed for greenness or area Jewish ethnicity.
