项目摘要

Food, energy, and water (FEW) are essential to sustain human life and well-being. To meet the growing demands of human population that is expected to reach 9.6 billion by 2050, the global and regional capability in providing abundant and affordable FEW will be increasingly important to social stability and economic development. Excessive nitrogen loading to water systems during food production has long been a serious problem for humans to access clean water, while the increasing water demand by energy production further exacerbates water scarcity and pollution. This project addresses an important research challenge at the FEW nexus: How can we balance Food-Energy-clean Water (FEWc) production, both spatially and temporally, with limited resources and changing environment? The project focus is on the Mississippi River Basin (MRB) in the U.S. and the Yellow River Basin (YRB) in China because these two basins are of global importance and are facing paramount challenges in meeting the growing demands for FEW. MRB, the largest river basin in North America, drains about 41% of the conterminous U.S. and most of the U.S. Corn Belt. The YRB, the second largest river basin in China, drains 11.5% of land area in China and is a key food and energy-producing region supporting 107 million residents. Research outcomes from this project will shed light on optimizing resource use efficiencies and predicting FEWc sustainability in the context of multiple-factor global changes including climate change, air pollution, urbanization, land and water use changes, and social-economic development. This project will foster science communication and stakeholder engagement for critical issues in the FEWc nexus, through summer school program, workshops and conferences, and university's broad strategy of external engagement in both U.S. and China. This project will also assist policymakers in making informed decisions regarding future policies that will enhance the quality and quantity of food, energy, and clean water.The overarching goal of this project is to understand and quantify the complex interactions and feedbacks within the FEWc system towards a basin-scale sustainable FEW provision (that is, to optimize resource allocation for maximizing crop production and energy generation and minimizing water pollution). The project will build an integrated systems modeling framework that incorporates crop, hydrological-biogeochemical, energy, and economic models, to advance our understanding and quantification of the complex interactions within the FEWc nexus, and predict FEWc sustainability under future climate and resource use scenarios at a basin level. The integrated systems model will be tested on the MRB (a Clean Water-targeted FEW) and the YRB (a Water Conservation-targeted FEW), to examine the limiting factors of FEWc nexus in these two intensively-managed while contrasting river basins. Through modeling assessment and predictions, the U.S.-China joint research team will test a series of hypotheses on spatiotemporal variations in limiting factors, sustainability of FEWc, and management potentials across these two river basins from 1960 to 2050. Benefiting from a U.S.-China joint program, such between-basin comparison will test different emphasis of FEWc connections, and form a quantitative and computational modeling tool that is applicable to other intensively-managed landscapes with similar FEWc conflicts across the world. The project will 1) characterize the FEWc dynamics and the mechanisms underlying natural and anthropogenic driving forces; 2) build an integrated systems modeling framework that simulates interactions, feedback, and socioeconomic constraints of FEWc at a basin scale; 3) assess and predict the roles of resource use and management practices in pursuit of FEWc in the context of global changes. The management options verified by this modeling framework will potentially change cultivation practices, energy structure, and most importantly, increase supply of clean water to inhabitants.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

食物，能量和水（很少）对于维持人类的生活和福祉至关重要。为了满足人口日益增长的需求，预计到2050年将达到96亿，提供丰富且负担得起的少数人的全球和地区能力将对社会稳定和经济发展变得越来越重要。长期以来，人类进入清洁水的氮气系统过多的氮气负载一直是一个严重的问题，而能源生产的水需求增加进一步加剧了水的稀缺性和污染。该项目应对少数Nexus的重要研究挑战：在空间和时间上，我们如何平衡食品能量清洁水（LICK）的生产，资源有限和环境不断变化？该项目的重点是美国的密西西比河盆地（MRB）和中国的黄河盆地（YRB），因为这两个盆地具有全球重要性，并且在满足对少数人的日益增长的需求方面面临着至高无上的挑战。 MRB是北美最大的河流盆地，大约占美国和美国大部分玉米带的41％。 YRB是中国第二大河流盆地，占中国土地面积11.5％，是一个支持1.07亿居民的关键食品和能源生产地区。该项目的研究成果将揭示优化资源使用效率的优化，并在多因素全球变化的背景下预测少量可持续性，包括气候变化，空气污染，城市化，土地和水利用变化以及社会经济发展。该项目将促进科学沟通和利益相关者的参与，以解决少数情况下的关键问题，通过暑期学校计划，研讨会和会议以及大学在美国和中国的外部参与的广泛战略。该项目还将协助决策者做出有关未来政策的明智决定，这些决策将提高食品，能源和清洁水的质量和数量。该项目的总体目标是了解和量化少数C系统中对盆地规模可持续性的复杂相互作用和反馈，以供可持续发展（以少量提供），以优化提供的资源分配，以最大化作物生产和最大程度地批准作物和最低量化。该项目将建立一个集成的系统建模框架，该框架结合了农作物，水文地球化学，能源和经济模型，以促进我们对少数几个Nexus中复杂相互作用的理解和量化，并在未来的气候和资源使用场景下在盆地层面上预测少数可持续性。集成系统模型将在MRB（以较清洁的水为少数）和YRB（以供水为少数）上进行测试，以检查这两个强化管理的同时对比河流盆地的限制因素。通过建模评估和预测，美国 - 中国联合研究团队将测试一系列关于限制因素的时空变化的假设，从1960年到2050年，这两个河流盆地之间的限制因素，少数可持续性以及管理潜力。从美国 - 芝纳（Us-China世界各地有类似少量冲突的景观。该项目将1）表征少量动力学和自然和人为驱动力的基础机制； 2）构建一个集成的系统建模框架，该框架模拟了盆地规模上很少有少数C的相互作用，反馈和社会经济约束； 3）在全球变化的背景下，评估和预测资源使用和管理实践在追求少数c方面的作用。该建模框架验证的管理选项将有可能改变培养实践，能源结构，最重要的是，增加向居民的清洁水供应。该奖项反映了NSF的法定任务，并认为值得通过基金会的知识分子的评估来进行评估，并具有更广泛的影响。
