Temporally, there is a substantial “lag time” in realizing positive climate impacts due to the 100-year residence time of atmospheric CO2;however, additional motivators for shifting towards an agroecological food system exist in the shorter-term including advancement of social, economic, health, and food justice goals. More complex representations of the food climate nexus exist showing cascading interactions between the food system, climate system, and potential adaptation/mitigation measures. The IPCC Land Use report includes a figure showing complex interlink ages between the climate system, food system, ecosystem , and socio-economic system, operating at multiple scales, from global to regional . Ultimately both complex and more simple diagrams are pointing towards opportunities for food systems actions to reduce and remove atmospheric GHG concentrations. However, doing so without compromising important social justice goals requires coordination and inclusive local food system planning. Debates in the agroecological food system research center around how best to achieve food systems and related social change and are discussed further in section 1.2.1 below. Emissions inventories quantify the greenhouse gas impact of food systems using various assumptions and “boundaries” between food and other sectors, such as transportation, buildings, and electricity generation. Estimates range from 8-9% of total greenhouse gas emissions attributable to “agriculture” in California and the United States , to 33% of total emissions attributable to the “global food system,” including fertilizer manufacture, food storage, and packaging . As Niles et al. state in a recent paper, “It is estimated that agriculture and associated land use change account for 24% of total global emissions , while the global food system may contribute up to 35% of global greenhouse gas emissions . As a result, food systems—not just agricultural production—should be a critical focus for GHG mitigation and adaptation strategies” . And yet, current research on climate change mitigation in the food sector focuses on the production element,rolling bench without fully exploring other system elements in terms of leverage points, synergies, and trade offs in mitigation and adaptation efforts.
It is important to consider a holistic accounting of greenhouse gas emissions from the industrial food system, including the manufacturing of nitrogen fertilizers and herbicide/pesticide chemicals; fuel for powering farm equipment; dietary preferences; and processing, packaging, and refrigeration processes, in order to optimize emissions reductions and carbon removal and maximize adaptation co-benefits of mitigating the climate crisis through transforming the food system . Critical food systems scholars and organizations aligning with the agroecology paradigm point out several dimensions of necessary action-research to build towards a climate friendly food system, including regenerative food production, minimizing corporate influence, preventing further consolidation of corporations, promoting re-localization of food systems activities, and rebuilding a policy climate with accountable elected officials acting in the best interest of society, environment and democracy . Relocalizing food systems is credited by scholars of agroecology as “an important factor in seeking solutions to the multiple crises” that cities are currently facing, including “environment, climate change, health, social inclusion and waste management” . Agroecology scholarship spans governance scales and nations, the urban and the rural, and is best understood through the lens of the food system , weaving together production and other system elements . The agroecological food system paradigm is framed by some scholar-activists as standing in direct contrast to the dominant industrial paradigm and the Law of Exploitation; it is “centered on the Earth and small-scale farmers, and especially women farmers… ecological food systems are local food systems. Sustainability and justice flow naturally from the Law of Return and from the localization of food production. The resources of the Earth… are managed as a ‘commons,’ or shared spaces for communities” . Other scholars such as Elinor Ostrom and David Bollier employ different philosophical and epistemological approaches to suggest management approaches grounded in cooperation and the commons. Ostrom famously posited eight principles for managing a commons, in direct response to Hardin’s “Tragedy of the Commons,” and she was awarded the Nobel Prize in Economics in 2009 for her efforts. Bollier’s book “Think Like a Commoner” frames an alternative political economy, a paradigm of “working, evolving models of self-provisioning and stewardship that combine the economic and the social, the collective and the personal. It is humanistic at its core but also richly political in implication, because to honor the commons can risk unpleasant encounters with the power of the Market/State duopoly” .
Bollier goes on to use words and phrases such as “bottomup, do-it-yourself styles of emancipation,” “new forms of production,” “open and accountable forms of governance,” “healthy, appealing ways to live,” and “pragmatic yet idealistic” to describe the paradigm of the commons. Inherent in both agroecology and the commons literature is the goal of returning to producers and individuals the power to self-determine systems of production and governance. Agroecological scholars increasingly engage in articulations of a vision for food system transformation, ranging from a radical overthrow of the status quo to more gradual shifts to current practices . Agroecological research is described as “transdisciplinary, participatory, and change-oriented” , and agroecology is commonly defined as a “science, practice and movement” . However, there is debate among food system scholars around how change is enacted. Some argue that agroecology is the best way to “feed the world,” and in fact, small agroecological farmers are already producing the majority of food consumed by the growing human population on a small percentage of total agricultural lands . Others argue that the land requirements of feeding a growing population through agroecological, regenerative1, and/or organic farming practices would be so large that land use change would exacerbate rather than ameliorate negative climate impacts associated with food production. These “land sparing vs. land sharing” and “feed the world debates” co-exist with debates around how to enact local food system reforms. I engage primarily with the local food system reform; my findings and contributions do not speak directly to the larger global land use and world hunger debates. Rather than arguing for radical and immediate food system revolution, the three cases presented in this dissertation illuminate opportunities for the current food system to improve along dimensions of sustainability, climate resilience, and education, presenting social and ecological benefits of local food system shifts. The cases advance an argument justifying and valorizing the existence of small farms, more easily able to provide social, ecological, and educational benefits to communities than environmentally destructive industrial farms. These benefits are not guaranteed or inevitable, however, when food systems relocalize or small farms focus on regenerative practices; they require public investment, civic engagement, and participatory action-research to sustain, safeguard, and enable their existence. 1.2.2 Local food systems are inherently complex, social-ecological systems . Food systems researchers bring to the fore “questions such as food…nourishing bodies, soils as living organisms, urban gardens as life-sustaining infrastructure… while taking issues as money, location, skin colour, gender, and social status seriously… Food issues cannot be treated as purely socio-political, neither as mere ecological or agronomic… They are co-constructions of water, people, investment flows, soil organisms, and more.
Agroecology captures this co-construction” . This excerpt nicely unites the theoretical frames of agroecology and SES,dry rack cannabis which both endeavor to explain and characterize human-nature interactions. Building a local food system requires an understanding of interdisciplinary topics and collaboration with diverse stakeholders , implicating systems of education in developing personal as well as institutional capacity for working in interdisciplinary, highly collaborative, environmentally literate teams. The chapters that follow investigate food systems research questions in the contexts of the San Juan Islands in Washington State, and the East Bay region of the San Francisco Bay Area. While all chapters engage with food systems holistically, each chapter enters into the food systems research question from a different element of the system. The second chapter focuses on the production side, introducing a case study of small-scale sustainable farming at the community scale on Lopez Island. The third chapter presents a food access and distribution research project taking place in the East Bay, investigating pathways through which urban produced foods do make it into the hands of food insecure consumers. The fourth chapter uses the lens of education to present an evaluation of a food and climate change curriculum, illustrating how climate change education and food systems research can work together to achieve common goals . The conclusion synthesizes key findings from all three chapters, pointing out what bigger picture food system questions are answered as well as questions requiring further investigation in the arena of relocalizing climate-friendly food systems. Small farms and farm-based education are ideal prototypes to investigate and disseminate work in this direction. Key strands of literature running throughout the paper include the literature on agroecology and emerging research on its application to the urban context- urban agroecology . Chapter 2 engages with the agroecological paradigm for food systems reform in a rural context, and Chapter 3 turns over new questions in the urban East Bay context. The chapter draws on scholarship from a recent RUAF magazine titled “Urban Agroecology,” that proposes UAE “not as a goal, yet an entry point into, and part of, much wider discussions of desirable presents and futures… [it is] a stepping stone to collectively think and act upon food system knowledge production, access to healthy and culturally appropriate food, decent living conditions for food producers and the cultivation of living soils and biodiversity, all at once” . Agroecology and UAE have important implications for how food systems education should be conducted , which are implicit in the pedagogical foundations underpinning the food and climate curriculum in Chapter 4.
The chapters, with their diverse research questions and publication outlets, push back against a food system that destroys human and environmental health alike, and seek out climate friendly alternatives through collaborative, participatory research projects. The research presented in chapters 2, 3, and 4 make the case for diverse values and benefits associated with relocalizing sustainable and equitable food systems centered around small diversified farms, in places where this type of food system transformation is sought. Rather than arguing for the complete overthrow of the current industrial food system, the primary contribution of these cases is to argue that shifts to current practices are both necessary and possible yet must be supported by appropriate and enabling governance structures. There are social, ecological, and educational benefits to adopting agroecological food system practices, but it is difficult to enact these practices holistically and systemically across food system elements in the current U.S. political economy. The cases offer lessons or “pilots” that are relevant to the operations of large-scale farms and industrial processes as well as small scale, agroecological operations: through adding plant diversity and minimizing soil disturbance, for example, numerous benefits can be achieved for farmers , for local ecology, and for global climate change. Therefore, findings implicate the policy and planning domain in terms of action needed to sustain and scale positive food system reform impacts, on a variety of levels and with attention to social justice implications. The findings also make important contributions to methods of climate change communication and education: effective CCE will manifest differently in different contexts and must allow for each audience to express the environmental concerns that are most pressing, immediate, and relevant in that context. Through considering food systems and climate systems holistically, opportunities for public health benefits, local environmental improvements, and educational growth can be realized. There is an added incentive on Lopez to adopt self sufficient and soil regenerating farming practices at the community scale due to its geographic isolation in combination with rocky, relatively poor soil quality. This “island incentive” is important to factor in when considering the widespread adoption of sustainable agriculture on Lopez; as the San Juan County Agricultural Strategic Action Plan reports, “islanders naturally place a high value on food security and may benefit from their isolation to preserve genetic diversity, for example, by establishing an organic seed industry” . As food supply chains in today’s globalized food system are increasingly threatened by natural and climate-exacerbated disasters, all communities will soon have increased incentives to invest in sustainable food production as a form of resilience, food security, and climate adaptation.
