PI姓名：大卫沃特金斯提案编号：1639342职务：感染/T3：减少家庭食物，能源和水的消耗：对保护措施和影响的定量分析机构：密歇根理工大学美国家庭层面行动的变化有可能通过减少食物，能源和水的消耗来减少温室气体（GHG）排放和气候变化。该项目将确定减少家庭FEW消费的潜在干预措施，在两个社区的参与家庭中测试各种选择，并收集数据以开发新的环境影响模型。它还将确定家庭消费行为和具有成本效益的干预措施，以减少少数能源的使用。研究见解可以应用于增加家庭层面的个人福祉，改善少数资源安全，减少与气候相关的风险，并提高美国的经济竞争力该项目将招募，培训和毕业20多名学生和早期职业科学家来自代表性不足的群体。学生将有资格参加交流，与荷兰的合作者进行跨学科研究，荷兰是一个高度工业化的国家，人均使用的能源和水比美国少20%。该方法包括：1）互动的角色扮演活动和定性访谈的房主; 2）家庭调查，以检查现有的态度和行为有关的少数消费，以及可能的方法和障碍，以减少消费;和3）实验研究的住宅家庭在两个案例研究社区，选择代表美国郊区家庭和适当的比较实验。这些研究将反复审查减少家庭FEW消费的方法，测试可能的干预战略，并为开发系统模型提供数据，以量化家庭FEW资源流动和排放的影响。将开发一个基于消费的生命周期评估（LCA）模型，为家庭决策和干预策略的设计提供准确的信息。LCA模型将包括第一个已知的家庭粮食消费影响的农场到餐桌的表示，食物浪费和取水的空间明确库存，以及电力部门的多层次价格响应模型。通过转化少数消费的影响，结果将确定“热点”和具有成本效益的家庭干预措施，以减少生态足迹。在生命周期评估模型中应用一套气候和技术情景，将为采用技术的潜在好处提供更多的见解，为决策提供信息。在本研究中开发的环境影响模型、家庭消费跟踪工具和角色扮演软件将是通用的，并在项目结束时公开提供，以告知未来的教育、研究和外联活动。

PI Name: David WatkinsProposal Number: 1639342Title: INFEWS/T3: Reducing Household Food, Energy, and Water Consumption: A Quantitative Analysis of Interventions and Impacts of ConservationInstitution: Michigan Technological UniversityChanges in household-level actions in the U.S. have the potential to reduce rates of greenhouse gas (GHG) emissions and climate change by reducing consumption of food, energy and water (FEW). This project will identify potential interventions for reducing household FEW consumption, test options in participating households in two communities, and collect data to develop new environmental impact models. It will also identify household consumption behavior and cost-effective interventions to reduce FEW resource use. Research insights can be applied to increase the well-being of individuals at the household level, improve FEW resource security, reduce climate-related risks, and increase economic competitiveness of the U.S. The project will recruit, train, and graduate more than 20 students and early-career scientists from underrepresented groups. Students will be eligible to participate in exchanges to conduct interdisciplinary research with collaborators in the Netherlands, a highly industrialized nation that uses 20% less energy and water per person than the U.S.This study uses an interdisciplinary approach to investigate methods for reducing household FEW consumption and associated direct and indirect environmental impacts, including GHG emissions and water resources depletion. The approach includes: 1) interactive role-playing activities and qualitative interviews with homeowners; 2) a survey of households to examine existing attitudes and behaviors related to FEW consumption, as well as possible approaches and barriers to reduce consumption; and 3) experimental research in residential households in two case-study communities, selected to be representative of U.S. suburban households and appropriate for comparative experiments. These studies will iteratively examine approaches for reducing household FEW consumption, test possible intervention strategies, and provide data for developing systems models to quantify impacts of household FEW resource flows and emissions. A FEW consumption-based life cycle assessment (LCA) model will be developed to provide accurate information for household decision making and design of intervention strategies. The LCA model will include the first known farm-to-fork representation of household food consumption impacts, spatially explicit inventories of food waste and water withdrawals, and a model of multi-level price responsiveness in the electricity sector. By translating FEW consumption impacts, results will identify "hot spots" and cost-effective household interventions for reducing ecological footprints. Applying a set of climate and technology scenarios in the LCA model will provide additional insights on potential benefits of technology adoption for informing policymaking. The environmental impact models, household consumption tracking tool, and role-playing software developed in this research will be general purpose and publicly available at the end of the project to inform future education, research and outreach activities.
