1664375RayFood security is civilization's next critical challenge, as the current world population of seven billion is projected to increase to more than nine billion by 2050. The United States (US) will face pressure to produce more food and feed for export, straining its energy and water resources and impacting ecosystem services. This three-day workshop will bring together experts from the fields of agronomy, agricultural economics and trade policy, water resources science/engineering, atmospheric sciences, and natural resource management to further investigate the issues and to develop new recommendations in the context of sustainability and water productivity. The workshop will be held in Bangalore, India (at the campus of the Indian Institute of Science), March 1 - 3, 2017.Intensity of agriculture, excess pumping, and climatic (rainfall) shifts are straining many regional aquifer systems in the US and around the world. This workshop will address the pressing questions of how to better balance demands on these aquifers under the current pumping stresses, and help identify the cropping management systems that will be necessary to cope with future climatic shifts. The collaboration will enable US and Indian researchers to share research and expertise aimed at solving the challenges of producing more food with less water and energy, while protecting the quality of scarce freshwater resources for human consumption and ecosystem services. The researchers will benefit from receiving international science perspectives as well as socio-economics perspectives at the nexus of food-energy-water. The outcomes of the workshop will advance national discussion about innovations at the nexus of food-energy-water, for which NSF has committed significant investments. The main goal of the proposed workshop is to address societal challenges in feeding humanity in the coming century and how the nexus between food, water and energy can be exploited to address sustainability challenges. Although these challenges are different in India and United States because of the scale of mechanization, resources availability, and other factors, the workshop will address differences and similarities in these challenges to develop mutually beneficial solutions. The specific objectives of the workshop include: 1. Identify innovative methods to improve water and energy use efficiency in the context of the nexus in both Indian and US settings, 2. Understand how the nexus concept in the food, energy and water systems can be a driver in economic and social decision making. To address food security issues, researchers have started to estimate current yield gaps, which represent the difference between current yield and the maximum yield that can be obtained under optimum management conditions. Efforts are underway to develop a yield gap analysis on a global scale to delineate areas where there is potential to increase crop yields. In order to analyze the sustainability of enhanced production of food crops (whether in the U.S. or elsewhere in the world) one needs to do the following in a step-wise manner: (1) analyze the yield gap for a given crop or suite of crops through crop modeling with optimal management scenarios and selection of proper crop hybrids; (2) for various scenarios in yield gap, estimate the water and nutrient fluxes leaving the root zone; (3) using appropriate numerical models, estimate the groundwater level changes, stream depletion, and changes in water quality in the aquifer based on the pumping needs and return fluxes of water and nutrients; and, (4) simulate optimal power use for irrigation systems. This workshop will lead to development of realistic and transferable management scenarios, tools and technologies to address societal challenges in food, energy and water security. Graduate students and postdocs as well as researchers that are in early stages of their careers will be encouraged to participate. The proceedings from the workshop will be published in electronic form, and widely shared by the Nebraska Water Center with potential stakeholders through newsletters, press releases and two annual sponsored faculty retreats.

1664375雷食品安全是文明的下一个关键挑战，因为目前的70亿人口预计到2050年将增加到超过90亿。这个为期三天的研讨会将汇集来自农艺，农业经济学和贸易政策，水资源科学/工程，大气科学和自然资源管理领域的专家，以进一步研究这些问题，并在可持续性和水生产率的背景下开发新建议。该研讨会将于2017年3月1日至3日在印度班加罗尔（印度科学院的校园）举行。农业强度，过量的抽水和气候（降雨）转变正在扭曲美国和世界各地的许多区域含水层系统。该研讨会将解决如何在当前的抽水应力下更好地平衡这些含水层的紧迫问题，并帮助确定应对未来气候变化所必需的裁剪管理系统。该合作将使我们和印度的研究人员能够分享旨在解决使用更少的水和能源生产粮食的挑战，同时保护稀缺的淡水资源的质量，用于人类的消费和生态系统服务。研究人员将受益于接受国际科学的观点以及食品能量水的联系的社会经济观点。研讨会的结果将推进有关食品能量水的联系的全国性讨论，而NSF为此投资了大量投资。拟议研讨会的主要目标是应对未来世纪喂养人类的社会挑战，以及如何利用食物，水和能源之间的联系以应对可持续性挑战。尽管由于机械化的规模，资源可用性和其他因素的规模，这些挑战在印度和美国是不同的，但研讨会将解决这些挑战的差异和相似之处，以开发互惠互利的解决方案。研讨会的具体目标包括：1。确定在印度和美国环境中Nexus背景下提高水和能源利用效率的创新方法，2。了解食品，能源和水系统中的Nexus概念如何成为经济和社会决策的驱动力。为了解决粮食安全问题，研究人员已经开始估计当前的收益差距，这代表了当前收益率和在最佳管理条件下可获得的最大收率之间的差异。正在努力在全球范围内制定产量差距分析，以描绘有可能增加农作物产量的地区。为了分析增强食品作物生产的可持续性（无论是在美国还是世界其他地方），需要以逐步的方式进行以下操作：（1）通过具有最佳的管理场景和适当的作物混合动力的最佳作物建模，分析给定农作物或作物套件的产量差距； （2）对于产量差距的各种情况，估计离开根部区域的水和营养通量； （3）使用适当的数值模型，根据泵送需求和返回水和养分的通量，估计地下水位的变化，溪流耗竭以及含水层的水质变化； （4）模拟用于灌溉系统的最佳功率使用。该研讨会将导致开发现实且可转让的管理场景，工具和技术，以应对食品，能源和水安全方面的社会挑战。将鼓励研究生和博士后以及在职业生涯早期阶段的研究人员参加。研讨会的程序将以电子形式发布，并由内布拉斯加州水中心通过新闻通讯，新闻稿和两次年度赞助的教师务虚会，并由内布拉斯加州水中心与潜在的利益相关者进行广泛共享。
