我们开发了可持续性的物理/生物方面的三个量化指标。它们的基础是资源枯竭、依赖外部补贴和自然循环中断。我们将这些指标应用于堪萨斯的一个农业县，使用能源，水，土壤和氮作为numeraires。大通县的9/10致力于肉牛放牧，1/10致力于行栽和圈养动物饲养。范围生产是相对非消耗性的，独立的，非破坏性的。种植业更消耗，依赖和破坏，但与其他农业地区相比。我们讨论了这种模式，介导的缺席土地持有和低人口密度，权衡对经济收入。除能源外，所有分析都只涉及直接流量（例如跨越国界的实际数量）。在能源方面，我们亦估计其他地方为生产进口非能源产品及服务而消耗的能源。
We develop three quantitative indicators of the physical/biological aspect of sustainability. They are based on depletion of resources, dependence on outside subsidies, and disruption of natural cycles. We apply the indicators to an agricultural county in Kansas, using energy, water, soil, and nitrogen as numeraires. 9/10 of Chase County is dedicated to range beef cattle grazing and 1/10 to row-cropping and confinement animal feeding. Range production is relatively non-depleting, independent, and non-disrupting. Cropping is more depleting, dependent, and disrupting, but comparable with that in other agricultural areas. We discuss how this pattern, mediated by absentee land-holding and low human population density, trades off against economic income. With the exception of energy, all analyses are only in terms of direct flows (e.g. actual amounts crossing the county boundary). For energy, we also estimate the energy consumed elsewhere to produce imported non-energy goods and services.
