This paper explores the structure and dynamics of organic commodity sy
stems in California. Employing a commodity systems analysis, we conduc
ted approximately seventy semi-structured interviews with key players
along the northern California organic vegetable commodity chain, looki
ng at the internal dynamics of each node as well as the linkages betwe
en them. Codification of the term 'organic,' which has contributed to
the recent growth in the organic foods industry, has also created econ
omic rents and unique opportunities for agribusiness accumulation. We
argue that agribusiness capital is penetrating the most high-value seg
ments of organic vegetable commodity chains, despite the prevalence of
practices and ideologies which countervail trends in conventional foo
d provision. Agronomic and marketing practices increasingly mirror tho
se of conventional agriculture. We also found several examples of 'app
ropriationism,' where processes once integral to the farm have been ta
ken off and reconfigured as inputs, and 'substitutionism,' where indus
trial activity accounts for a rising proportion of value added.
