A recent study by McGee from the University of Oregon has led to discussions in international media and on the web. This study addresses an interesting question and applies advanced statistics for its analysis. However, we identify several methodological flaws that invalidate the results. First, McGee tests a hypothesis that does not correspond to his main question and which does not allow McGee to derive the conclusions that are drawn in his paper and reported in the media coverage. Second, the (...) data used are not adequate for the analysis because: i) the dependent variable does not reflect the greenhouse gas emissions characteristics of organic agriculture, ii) the explanatory variables neglect the livestock sector, and iii) trade aspects are missing. Third, McGee fails to discuss his findings in the light of quite a substantial body of experimental, bio-physical research from the US and elsewhere. (shrink)

Because organic certification standards institutionalized a product-based rather than process-based definition, certified organic produce can be grown on large-scale industrial monocrop farms. Besides toxicity of inputs, these farms operate in much the same way as conventional production. Scholars emphasize the fact that labor rights have been left out of certification criteria, and because of that, organic farms reproduce the same labor relations as conventional. Empirical studies of organic farm labor, however, rely primarily on the perspective of farmers. In this study, (...) I ask the farmworkers themselves how harvesting on organic farms compares to conventional, and found that working in organic negatively impacts farmworker livelihoods. Qualitative interviews with 36 strawberry harvesters in Oxnard, California reveal that farmworkers make more money in conventional strawberry production because of the interaction between wage structure and size of the berry. Conventional strawberries are larger and therefore fewer of them fill up a box. Farmworkers routinely pick more boxes in conventional than in organic, thus earning more, since under the piece rate system, farmworkers are paid per box. With short-term economic survival rather than long-term occupational health concerns in mind, strawberry harvesters would rather work on conventional farms because “la fresa orgánica es más chiquita”.
