Despite the growing importance of cities as biogeochemical hotspots, little is known about factors influencing elemental fluxes through individual households, even though the aggregate consumption by households likely has a substantial effect on fluxes of major elements like carbon (C), nitrogen (N), and phosphorus (P) that have implications for local, regional and global pollution. The overall goal of this interdisciplinary research project is to couple human behavior with flows of macroelements (C, N, and P) through households. The investigators will quantify total fluxes of C, N, and P through households in the Twin Cities of Minneapolis-St. Paul, Minnesota, and they will look to expand basic understanding of the factors that influence household choices regarding consumption and macroelement fluxes through households. The investigators hypothesize that element fluxes are highly variable and skewed, with relatively few households contributing disproportionately to overall fluxes. Another hypothesis to be tested posits that the magnitude of elemental fluxes through households can be predicted from knowledge of daily consumption choices along with long-term choices regarding household infrastructure, such as house size and lawn area. To test these hypotheses, 400 owner-occupied, single unit households in Ramsey County will be randomly selected to cover a range of household characteristics. These households will be studied using an intensive mail survey, a landscape inventory, and homeowner energy bills. Data will be entered into a previously developed Household Flux Calculator (HFC) model to generate fluxes of C, N, and P. Survey data will additionally be used to link element fluxes with factors related to human choices like attitudes, norms, perceived control, and demographic factors.This project is expected to integrate human choice and biophysical characteristics into a model of household biogeochemistry using a transdisciplinary approach that integrates biophysical and social research approaches. The project will provide research opportunities for post-docs, graduate students, and undergraduate students. By incorporating the HFC directly into classroom education, it will allow students to explore hypotheses regarding impacts of consumption. In addition, project outcomes will be used to help develop a new paradigm for pollution control, one based on source reduction and information feedback loops to guide adaptive management. This project is supported by an award resulting from the NSF competition focusing on the Dynamics of Coupled Natural and Human Systems.

尽管城市作为生物地球化学热点的重要性越来越重要，但对于影响各个家庭的元素通量的因素，尽管家庭的总消费可能对碳（C），氮气（N）和磷（P）等主要元素（例如，对地方和全局的含量）的主要元素产生重大影响，但鲜为人知。 这个跨学科研究项目的总体目标是将人类行为与宏观元素（C，N和P）通过家庭相结合。 调查人员将通过明尼阿波利斯-ST的双子城市的家庭量化C，N和P的总通量。保罗，明尼苏达州，他们将寻求扩大对影响家庭选择和大量元素通量通过家庭选择的因素的基本了解。 研究人员假设元素通量是高度可变且偏斜的，相对较少的家庭对整体通量的贡献不成比例。 要测试的另一个假设认为，可以通过对每日消费选择的知识以及有关家庭基础设施（例如房屋规模和草坪区域）的长期选择来预测通过家庭的元素通量的幅度。 为了检验这些假设，将随机选择400个在拉姆齐县的单位家庭，以涵盖一系列家庭特征。 这些家庭将使用密集邮件调查，景观清单和房主的能源账单进行研究。 数据将进入先前开发的家庭通量计算器（HFC）模型，以生成C，N和P的通量。调查数据还将用于将元素通量与与人类选择相关的因素联系起来，例如态度，规范，感知控制和人口统计学因素，这些项目将使用人类选择和生物物理学特征整合到家庭中的模型，并将其整合到家庭中。研究方法。 该项目将为研究生，研究生和本科生提供研究机会。 通过将HFC直接纳入课堂教育，它将允许学生探索有关消费影响的假设。 此外，项目成果将用于帮助开发一种新的污染控制范式，该范式基于源头减少和信息反馈循环，以指导自适应管理。 NSF竞争的奖励是由NSF竞争的奖励支持，该奖项的重点是耦合的自然和人类系统的动态。
