This research project will use modeling techniques that integrate agricultural land use, energy generation, and hydrologic systems to predict future food-energy-water (FEW) relationships. With the Central Valley, California (United States) and the Jing-Jin-Ji region (China) as case studies, a harmonized scenario-analysis approach will be developed to evaluate potential synergies and trade-offs of infrastructure development and policy priorities. Results from policy simulations will inform potential solutions to future resource limitations. In the U.S. case-study region, modeling will inform policy discussions by offering a more detailed depiction of land-use systems in the Central Valley, while accounting for the economic opportunity costs of agricultural land displacement under new policies and renewable energy-siting considerations. Additional simulation analysis will test alternative solutions to challenges in each region, including groundwater storage set-asides, new water trading schemes to assess whether these solutions are resilient to future socioeconomic, policy, and environmental conditions.While previous nexus studies have incorporated land use considerations for representing agricultural production possibilities, the dynamic feedback between large-scale renewable energy expansion, agricultural land resource management, and water resource demands under alternative future climate conditions needs further exploration as planned for this project. Furthermore, this research will explicitly inform updates to the publicly available California Value Integrated Network (CALVIN) hydro-economic modeling infrastructure for the Central Valley region by offering new perspective potential land use trajectories in the region under agricultural water demands that might evolve over time with renewable energy infrastructure investments and groundwater management dynamics. Harmonized scenario analysis in collaboration with the Chinese research team will provide a comparative assessment of nexus challenges and solutions under changing socioeconomic, policy, and environmental conditions. The research team will offer insight into how institutional constraints on the FEW nexus can impact optimal resource allocation and potential solutions that could improve sustainability outcomes in the FEW nexus.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.

该研究项目将使用集成农业土地利用，能源生产和水文系统的建模技术来预测未来的粮食-能源-水（FEW）关系。 将以中央谷、加州（美国）和京津冀地区（中国）为案例研究，制定一种协调一致的生态系统分析方法，以评价基础设施发展和政策优先事项的潜在协同作用和权衡。政策模拟的结果将为未来资源限制的潜在解决方案提供信息。在美国的案例研究地区，建模将通过提供中央谷土地使用系统的更详细描述，同时考虑到新政策和可再生能源选址考虑下农业土地置换的经济机会成本，为政策讨论提供信息。额外的模拟分析将测试每个地区挑战的替代解决方案，包括地下水储存预留，新的水交易计划，以评估这些解决方案是否能适应未来的社会经济，政策和环境条件。虽然以前的关系研究纳入了土地使用考虑因素，以代表农业生产的可能性，但大规模可再生能源扩张，农业土地资源管理和未来气候变化条件下的水资源需求需要按照本项目的计划进一步探讨。此外，这项研究将明确通知更新的公开可用的加州价值集成网络（卡尔文）水文经济建模基础设施的中央谷地区提供新的视角潜在的土地利用轨迹在该地区的农业用水需求，可能会随着时间的推移与可再生能源基础设施投资和地下水管理动态。与中国研究团队合作进行的协调情景分析将在不断变化的社会经济、政策和环境条件下对关系挑战和解决方案进行比较评估。该研究团队将深入了解FEW关系上的制度约束如何影响最佳资源分配以及可能改善FEW关系中可持续性成果的潜在解决方案。该奖项反映了NSF的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
