Spatial localization, often demarcated by food miles, has emerged as the dominant theme in movements for more socially just and environmentally benign alternative food systems, especially in industrialized countries such as the United States. We analyze how an emphasis on spatial localization, combined with the difficulty of defining and measuring adequate indicators for alternative food systems, can challenge efforts by food system researchers, environmental writers, the engaged public, and advocacy groups wanting to contribute to alternative food systems, and facilitates exploitation (...) by the mainstream players using “localwash” to maintain the status quo. New indicators are urgently needed because research shows that spatial localization in general and minimized food miles in particular are not adequate or even required for most of the goals of alternative food systems. Creating indicators to operationalize goals for alternative, local food systems requires asking the right questions to make sure indicators are not misleading us: What are the goals of alternative food systems? What actions and policies will most effectively achieve those goals? What is the potential of reducing food miles as an action and a policy for achieving goals? What are the best indicators for measuring progress toward goals? We discuss how these questions can be answered for a wide range of alternative food system goals via four categories according to the role of food miles reduction as an action and policy in promoting them: necessary and sufficient, necessary but not sufficient, potentially important, and potentially supportive.

Our question “How many chickens does it take to make an egg?” was inspired by the successful replacement of egg-based mayonnaise with plant-based mayonnaise in general dining at the University of California, Santa Barbara, in order to increase animal welfare. Our indicator of improved animal welfare due to decreased egg consumption was the reduction in number of chickens in the stressful and unhealthy conditions of the US egg industry. To measure this we calculated the ratio of chickens to eggs and (...) found it takes 6.3 chickens to make 1000 eggs. This equals 158 eggs per chicken, less than half the amount of eggs per laying hen because of mortality from hatching to entering the laying flock, including the disposal of male chicks. In addition, greenhouse gas emissions, irrigation water, reactive nitrogen, and land use would be reduced 43–98% from that of eggs. While the impact of plant-based mayonnaise was relatively small, we also estimated the substitution of eggs with tofu, which had a much greater impact: substituting 50% of eggs with tofu in first-year student breakfasts on all UC campuses would reduce the number of chickens in the egg industry by 9245. If this substitution was made by the US population, the welfare and environmental benefits would be 29 thousand times greater. Reducing egg consumption would greatly improve chicken welfare even if welfare certified eggs are replaced, since the requirements of the most commonly used chicken welfare certification programs do relatively little to reduce chicken suffering.

This article presents a holistic framework for understanding the scienceof plant breeding, as an alternative to the common objectivist andconstructivist approaches in studies of science. It applies thisapproach to understanding disagreements about how to deal with yieldstability. Two contrasting definitions of yield stability are described,and concomitant differences in the understanding and roles ofsustainability and of selection, test, and target environments areexplored. Critical questions about plant breeding theory and practiceare posed, and answers from the viewpoint of the two contrastingdefinitions of yield (...) stability are analyzed, based on key publicationsin the field. Differences in answers to these questions appear to resultboth from the contingencies of plant breeders' experiences withparticular crop varieties and growing environments, and from differencesin social and institutional settings – plant breeding science isboth objective truth and social construction. The goal of using aholistic framework is to encourage discussion among plant breeders,farmers, social scientists, and others, of the bases for disagreementswithin plant breeding, in order to facilitate plant breeding'scontribution to a more environmentally, economically, and sociallysustainable agriculture.

Indigenous Zuni farming, including cultural values, ecological and biological diversity, and land distribution and tenure, appears to have been quite productive and sustainable for at least 2000 before United States influence began in the later half of the 18th century. United States Government Indian agriculture policy has been based on assimilation of Indians and taking of their resources, and continues in more subtle ways today. At Zuni this policy has resulted in the degradation and loss of natural resources for farming, (...) reduction in the number of Zuni farmers and their control over farming resources, individualization of rights in farmland, consolidation of farm fields, and declining biological diversity in agriculture. The Zuni Sustainable Agriculture Project with the Zuni Irrigation Association and the Zuni community, are now working to revitalize sustainable Zuni farming, based on traditional values, knowledge, and technology, combined with modern knowledge and technology where appropriate. The United States government can support these efforts through appreciation of the need for Zuni control and the potential value of cultural and biological diversity. (shrink)
