Catalog Course Description Cross-cultural survey of agroecological research methods, theoretical problems, policy issues, and ethical debates. Local knowledge and ethnoscientific bases of alternative agriculture. Comparative political ecology of agroecosystems with a focus on indicators of social equity and ecological sustainability. (5 credits) NSc/SSc
Focus and Themes of the 2024 Seminar. Our focus this year takes us beyond the more typical "farm to table" discourse and instead pursues critical investigations on the connections between soil and gut health. More precisely we will examine the relationship between the ecology of the soil rhizosphere and a healthy human gut microbiome. We will begin by learning about methods, theories, and ethics in agroecology, the ethnoscientific basis of sustainable agriculture. We will then examine how this agroecological framework can inform critical review of a vast set of scientific discourses on the impact of modern agricultural technologies on the rhizosphere and the human gut microbiomes. Each student will address the dirt-to-gut connection by developing a design proposal for an agroecological restoration project that draws connections between cultural and ecological integrity in our relations to land, water, and the entire 'web of life.'
My approach to the complex and challenging theme of "dirt-to-gut" is grounded in my own experiences as a decolonial biodynamic farmer with training in collaborative interdisciplinary research methods that allow me to integrate methods and materials from agroecology, ethnoedaphology and ethnopedology, and conservation biology with related studies in fields as diverse as risk science, epigenetics, foodways, nutrigenomics, diet and nutrition, and the study of Indigenous heritage cuisines.
Considering a wide range of risk science studies is an important part of this approach. This involves engaging the evidence offered by studies of the health of the rhizosphere and human gut microbiomes. This year we will focus on the effects of ubiquitous use of the herbicide glyphosate and its adjuvants and contrast conventional, organic, and biodynamic farming systems and their effects on the nutrient density of food and forage crops. We will engage a wide variety of scholarly and scientific discourses many of which are unfamiliar to us in the social sciences and humanities.
This approach is based on the principle that we do not have to be scientists to become scientifically literate but this also involves recognizing there are many pathways to practicing science including those based on Indigenous epistemologies. My ultimate aim is to introduce these varied epistemes and discourses to a new audience while also constantly working to "decolonize" the course texts by identifying Indigenous analogs, challenging binary constructs, and addressing erasures of Indigenous knowledge domains and other instances of epistemic violence.
Finally, given the $2.3 million in grants we are administering under the San Luis Food Sovereignty Initiative in the Culebra acequia watershed, we will be exploring one approach to addressing a community health crisis. Costilla County has a 15 percent rate of diabetes affecting near every family in this Spanish-Mexican-Genizaro community in south central Colorado. The initiative involves transforming the historic R&R Market (est. 1857) into a worker self-managed community food cooperative linked to local acequia farmers and youth apprentices. We will visit with the farmers, youth apprentices, community organizers, and Market staff over the entire three weeks of field-based instruction.
Note on Fig. 2 (above). Indigenous farmers have understood soil as a living organism for millennia and this knowledge is now confirmed by agroecological and related sciences. Evidence suggests soil health is the underpinning of environmental, community, and human health.
A decolonial approach to the dirt-gut problematic starts with the proposition that the land (soil) has suffered the same historical trauma and structural violence as Indigenous peoples displaced from ancestral homeland commons. Cultural genocide, soil erosion, and the decline of phyto-diversity are by-products of the same processes unleashed by settler colonialism. This violence is currently encapsulated in modernist corporate projects to patent life and control seeds resulting in certifiably catastrophic consequences for public health especially in the most vulnerable communities. How do we critically marshal these scientific discourses to ally with Indigenous perspectives on healing the colonial wounds affecting the health of the soil and our bodies?
Note on Figure 3 (above). The decline of agro-biodiversity is a major threat to food sovereignty and global food security. The decimation of crop phytodiversity is associated with changes in the nutrient density of major food crops. The decline is associated with settler colonial modernist projects involving agricultural biotechnologies and practices that degrade the rhizosphere (root zone) microbiome with possible effects on the human gut microbiome. Documented impacts of soil erosion, compaction, demineralization, and salinization as well as toxicity are affecting vital micro-organismic communities in the root zone. These changes also have profound and usually overlooked impacts on human health and wellbeing.

Learning Goals
- Become well grounded in the scholarly and activist discourses framing the field of agroecology especially with a focus on the transformative impact of Indigenous and Native studies.
- Learn about the interdisciplinary range of methods and materials used in and produced for and by students of agroecology, permaculture, biodynamics, etc. but above all value the epistemic disobedience grounded in the knowledge, belief, practice ensembles of deeper Indigenous sources.
- Understand the variety of recent theoretical developments including: decolonial; feminist; queer; Marxist; social movement; indigeneity; and alterity.
- Develop critical awareness of the social, cultural, ecological, and political economic effects of white settler colonialism and capitalism.
- Develop your capacity to critique capitalism in a manner that empowers existing and emerging alterNative solidarity economies.
- Become literate in the perspectives and principles of Indigenous epistemology; embrace the practice of epistemic disobedience and delinking of your own work from institutions, norms, and relations of settler colonial and capitalist domination.
- One does not have to be a "scientist" to become scientifically literate: This means learning to decode and understand peer reviewed scientific discourses.
- We also must understand that "Western" science is only one among many paths/paradigms to the development of knowledge systems about the human relationship to the environment. Ethnoscience is a term that refers to the thousands of Indigenous knowledge systems that avoid the subject/object dichotomy and the positivist separation of "facts" from "values" resulting in knowledge and praxis ensembles that promote resilient co-habitation of Earth's ecosystems.
Policies and Expectations
Attendance. Regular on-time attendance is encouraged. There is much that happens during class time that adds to your educational experience beyond what you can learn from just reading and writing. Students are to enter the classroom space with a positive mind and willingness to engage and be active participants with a community of learners. If an emergency arises which prevents you from attending, it is your responsibility to gather notes from your peers.
Assignments and late papers. All assignments are to be turned in on time or penalties will be assessed.
Class behaviors and civility. Any form of harassment against other students—including racist, sexist, homophobic/transphobic, or threatening comments and behaviors that create a hostile and unpleasant environment will not be tolerated and is a violation of university harassment guidelines and respectable human behavior. We will strive to create a classroom where respect for all people and diversity of opinion is the standard and desired. These rules apply to on-line sessions.
Academic honesty. Please adhere to the university’s academic standards including those governing academic dishonesty, including cheating, plagiarism (submitting the language, ideas, thoughts or work of another as one’s own), or fraud. The university considers plagiarism a serious academic offense, which subjects those engaging in the practice to severe disciplinary and grading consequences.
Disability statement. Students with special needs who need assistance should contact the Disability Resource Center immediately (http://www.washington.edu/students/drs/ (Links to an external site.)). Please meet with me early in the quarter if you require accommodations. I will make reasonable efforts to accommodate your special needs.
Religious accommodations. Washington state law requires that UW develop a policy for accommodation of student absences or significant hardship due to reasons of faith or conscience, or for organized religious activities. The UW’s policy, including more information about how to request an accommodation, is available at Religious Accommodations Policy (https://registrar.washington.edu/staffandfaculty/religious-accommodations-policy/) (Links to an external site.). Accommodations must be requested within the first two weeks of this course using the Religious Accommodations Request form (https://registrar.washington.edu/students/religious-accommodations-request/).
COURSE CALENDAR
REQUIRED READING: Before our first seminar meeting on July 21, I am asking all students to read and reflect on the text by Linda T. Smith from her book, Decolonizing methodologies. Chapter 8 presents "25 Indigenous projects" that will guide our critical readings of the course texts and also provide a framework for the development of the students' agroecology restoration design projects. The PDF may be downloaded here: Linda T. Smith, 1999. 25 Indigenous projects.
NOTE: It is also recommended that each student take time to watch this video before we meet for the first session of the seminar on July 23. The World According to Monsanto is a 2004 documentary film which makes an in-depth investigation into unlabelled, patented, genetically engineered foods that have quietly made their way onto grocery stores in the United States for the past decade. It voices the opinions of farmers in disagreement with the food industry and details the impacts on their lives and livelihoods from this new technology, and shines a light on the market and political forces that are changing what we eat.
