Ecological Biopower, Environmental Violence Against Animals, and the "Greening" of the Factory Farm
The promulgation of pollution control regulations governing factory farms has led to a striking new way of representing and intervening in the bodies of farmed animals: the body is being represented as a source of pollution, and various technological interventions, from genetic engineering to dietary changes, are being deployed to reduce pollution at the source. In this article I analyze this new technoscientific project through the theoretical lens of ecological biopower. Focusing on the industrial pork sector's efforts to keep the cost of complying with nutrient management regulations in check, the article examines the case of “environmental nutrition,” a dietary strategy that aims to reduce the excretion of nutrients from the bodies of swine. By highlighting whose diet is being changed in this approach and whose is not, I argue that environmental nutrition is as much about avoiding the exercise of ecological biopower over human beings as it is about exercising ecological biopower over farmed animals. I also argue that the pressing need to reduce the environmental impacts of factory farming is being used to justify new forms of violence against animals
Sheep, dingoes and kangaroos: new challenges and a change of direction 20 years on
Predation and competition are two primary forces limiting the extent to which sheep can be grazed in the Australian rangelands, particularly in Queensland. Dingo predation has been non-existent in much of the sheep zone since the localised eradication of dingoes in the early 1900s. Competition with kangaroos has been ever-present, but was previously managed (to some extent) by the commercial kangaroo harvesting industry. However, changes to dingo distribution and kangaroo densities and harvesting over the last 20 years have meant that dingo predation and kangaroo competition again threaten viable sheep production in the rangelands. Dingoes have increased their distribution and density in almost all sheep grazing areas and contemporary lethal control efforts are not preventing the decline of sheep. Loss of valuable international markets and moves to now harvest only adult male kangaroos means that the kangaroo harvesting industry produces little relief from kangaroo grazing pressure (given that kangaroo population growth is little affected by removal of adult males; see Finch et al. this volume). New approaches to dingo and kangaroo management are sorely needed to salvage and restore the production of sheep in the rangelands. In response, the installation and use of pest-proof fences is rapidly increasing in Queensland and other areas, facilitating, for the first time in nearly a century, the localised eradication of dingoes and the suppression of kangaroos to manageable numbers within fenced areas. We describe these challenges and opportunities for one site in particular (Leander Station), and offer a sheep grazier’s perspective on past and future use and management of problematic wildlife in sheep production zones
Euclidean Quadratic Forms and ADC Forms I
Motivated by classical results of Aubry, Davenport and Cassels, we define the
notion of a Euclidean quadratic form over a normed integral domain and an ADC
form over an integral domain. The aforementioned classical results generalize
to: Euclidean forms are ADC forms. We then initiate the study and
classification of these two classes of quadratic forms, especially over
discrete valuation rings and Hasse domains.Comment: 26 page
