- 요약Addressing climate change requires strong policy initiatives to reduce greenhouse gas (GHG) emissions across economic sectors. Agricultural GHG emissions are rarely regulated but are increasingly a focus of scientific and policy work. Agricultural sources present challenges to existing climate governance frameworks for several reasons: the spatial and temporal variations in emissions from farms make measurement, and thus management, difficult; technologies for emissions reductions are nascent and require further study on the effects of their implementation; and the existing financial and physical infrastructures of the US food system are resistant to change. Given these challenges, what types of policy are needed to address agricultural emissions and what types of barriers to implementation exist? More broadly, what types of climate policy are possible in the current political economy of US food systems?The state of California implemented legislation in 2016 mandating reductions in GHG emissions from agricultural sources, and in particular from the state's highly developed dairy industry. State incentives prioritizes the implementation of anaerobic digesters, which capture methane from dairy manure and produce biogas to be used as an energy source. This dissertation examines the implementation of California's unique approach to reducing dairy GHG emissions as a case study of climate policy for agriculture. A mixed-methods approach is informed by political ecology, industrial ecology, and critical food system studies. First, an examination of political discourses that question the legitimacy of state carbon calculations shows how modeling assumptions render dairy biogas renewable and reflect power asymmetries between industry and environmental groups. Second, a counterfactual Life Cycle Assessment of the environmental impacts of dairy biogas extends the scope used by the state's model to include emissions from dairy production. Allocation-based LCA modeling provide a more complete picture of the fuel's life cycle emissions and shows how GHG emissions from dairy systems may be considered for fuels derived from dairy manure. Third, a survey of California dairy operators examines respondents' perceptions and willingness to adopt climate technologies in relation to their current scale of production and management choices. Analysis of survey results hypothesizes that anaerobic digesters could exacerbate existing economic pressures on dairy operations by operating as a green version of the agricultural technology treadmill.California's case shows that climate governance faces significant barriers due to the concentration, consolidation and intensification of the agriculture sector. This is due in part to the industry's political influence, but also because agricultural treadmill dynamics make changes in farm management for purpose of mitigating GHG emissions difficult to implement. Successful climate policy for agriculture should address both the political and economic structures that shape our current food system.
