项目摘要

The resilience of human-nature systems at the nexus of food, energy, and water (FEW) is threatened by environmental change such as increasing climate extremes, growing population demands, and evolving land use. Actionable strategies for improving both U.S. and China's agricultural, economic, and environmental sustainability must be developed through better understanding of how their mutual interactions with climate affect the evolution of the coupled FEW systems. The research project integrates state-of-the-art knowledge and modeling capabilities in climate, hydrologic, agronomic, biogeochemical, engineering, and economic sciences. The investigation will build a framework to realistically couple, predict and apply interactive water, carbon, and nitrogen cycle processes with agricultural practices, resource management and government policies to address critical issues of vulnerability, resilience and sustainability in regional FEW systems. The U.S.-China comparison will determine the importance of human activities in enhancing or reducing FEW system resilience, and thereby to provide science-based decision support to navigate sustainable resources use for food and energy crops production. The project includes an international exchange program to support education of the next generation of scientists in a transdisciplinary research framework in which the cross-fertilization of ideas is central. Students will be engaged in all aspects of the project and collaborate with senior scientists in both U.S. and China teams, preparing these broadly trained researchers on new approaches critical for the future. The overarching goal of this project is to develop, evaluate, and apply a coupled modeling framework to address the adaptability of China's Food production-Energy development-Water supply systems (CFEW). The framework will incorporate environmental changes and human activities in the Yellow River Basin, where demands on these systems are in sharp conflict. The study will include the production of the main food and bioenergy crops; energy development from hydropower, coal reserves and biomass feedstocks; and the water supply management that includes reservoir operation, flood control, and irrigation strategy. The proposed approach explicitly incorporates interdependency, human-centric, and extremality hypotheses to enable deeper understanding of the natural-socioeconomic interactions underpinning China's FEW systems resilience and sustainability. The primary objectives are to: (1) develop CFEW to represent the multi-scale interactions and coevolution of regional FEW systems with climate and hydrologic processes responding to major environmental factors and human interventions; (2) understand key feedback mechanisms driving FEW systems and regional differences linking natural variations with human activities; (3) determine potential thresholds in these systems at which changes to human activities damage China's food, energy and water security and overall system resilience and adaptability, and (4) identify sustainable food and energy production pathways under limited land/water resources along with effective uses of the diversion water to contain these damages.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、能源和水 (FEW) 关系中的人与自然系统的复原力受到环境变化的威胁，例如极端气候的加剧、人口需求的增长和土地利用的变化。必须通过更好地了解两国与气候的相互作用如何影响耦合 FEW 系统的演变，制定改善美国和中国农业、经济和环境可持续性的可行战略。该研究项目整合了气候、水文、农艺、生物地球化学、工程和经济科学领域最先进的知识和建模能力。该调查将建立一个框架，将交互式水、碳和氮循环过程与农业实践、资源管理和政府政策实际结合、预测和应用，以解决区域 FEW 系统的脆弱性、弹性和可持续性等关键问题。中美比较将确定人类活动在增强或降低 FEW 系统复原力方面的重要性，从而为粮食和能源作物生产的可持续资源利用提供基于科学的决策支持。该项目包括一项国际交流计划，以支持在跨学科研究框架中对下一代科学家进行教育，其中思想的交叉传播是核心。学生将参与该项目的各个方面，并与美国和中国团队的资深科学家合作，为这些受过广泛培训的研究人员准备对未来至关重要的新方法。该项目的总体目标是开发、评估和应用耦合建模框架，以解决中国粮食生产-能源开发-供水系统（CFEW）的适应性问题。该框架将纳入黄河流域的环境变化和人类活动，而黄河流域对这些系统的需求存在尖锐冲突。该研究将包括主要粮食和生物能源作物的生产；水力发电、煤炭储量和生物质原料的能源开发；供水管理，包括水库调度、防洪和灌溉策略。所提出的方法明确纳入了相互依存、以人为中心和极端假设，以便更深入地理解支撑中国 FEW 系统弹性和可持续性的自然与社会经济相互作用。主要目标是：（1）开发CFEW来代表区域FEW系统与响应主要环境因素和人类干预的气候和水文过程的多尺度相互作用和共同进化； (2) 了解驱动 FEW 系统的关键反馈机制以及将自然变化与人类活动联系起来的区域差异； (3) 确定这些系统中人类活动变化损害中国粮食、能源和水安全以及整体系统复原力和适应性的潜在阈值，以及 (4) 确定有限土地/水资源下的可持续粮食和能源生产途径以及有效的粮食和能源生产途径。该奖项反映了 NSF 的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。
