食物、能源和水（少数）资源都是人类的基本需求。随着人口增长和经济增长，确保足够的粮食、能源和水以满足人类需求的挑战正在扩大。最近的一份可持续发展报告显示，2017年有7亿人露天排便，7.85亿人缺乏基本饮用水服务，8.2亿人营养不良（包括7.7亿人严重粮食不安全），8.4亿人无电可用（https://www）。sdgindex。org/reports/sustainable-development-report-2019/)。数十亿人正遭受水和能源不安全的困扰。具体而言，2017年有30亿人在家中缺乏基本的洗手设施，约30亿人无法获得清洁的烹饪燃料和技术，约48亿人面临人类水安全或生物多样性威胁。在2015年联合国批准的17项可持续发展目标中，“零饥饿”（目标2）、“负担得起的清洁能源”（目标7）、“清洁水和卫生设施”（目标6）分别是专门为粮食、能源和水设定的，而其他目标则与这三种资源密切相关。粮食生产和加工部门是最大的用水者和重要的能源消费者。量化食物、能源和水之间复杂的相互依赖关系对于实现可持续发展目标至关重要（Liu et al., 2018）。少数联系对人类适应各种重大挑战有很大影响，如极端气候和气候变化、人口增长和水资源短缺。1)在确定FEW关系的重大挑战和开发管理有限FEW资源的新方法方面取得了相当大的进展（例如Conway等人，2015年，Liu等人，2017年）。然而，这些方法的有效实施受到科学-政策-利益相关者互动背景下对少数关系权衡理解不足的限制（Liu et al., 2017）。缺乏科学的理解进一步阻碍了克服政策障碍和促进利益相关者接受的系统级工具的发展（Liu et al., 2018）。对FEW关系的评估需要从强调学科研究的线性“树”模型转向解决跨学科复杂性的“网络”模型（Liu et al., 2019）。在之前关于FEW Nexus的特刊（Khanna等人，2017年）的基础上，这个虚拟特刊（VSI）呼吁为FEW Nexus提供包括数据收集、工具开发和管理政策在内的贡献。其范围包括数据库开发、不同尺度的“少数民族”互动和建模、区域/国家间“少数民族”挑战和方法的比较分析、“少数民族”与极端气候和变化的联系，以及对“少数民族”政策和可持续发展的实际影响。该VSI旨在促进信息集成，开发系统建模技术，并探索基于nexus的可持续发展的管理策略和实践。VSI中的论文应该填补少数资源关系中的实质性知识空白，并为改进少数资源的生命周期管理提供路线图。鼓励对少数研究方向提供创新见解的提交。邀请原创研究论文和综述论文，讨论以下主题：
Food, energy, and water (FEW) resources are all basic human needs. With population increase and economic growth, challenges on securing sufficient food, energy, and water to meet human demand are amplifying. A recent sustainable development report indicates that in 2017 there were~ 700 million people practicing open defecation,~ 785 million people lacking basic drinking water services,~ 820 million people undernourished (including 770 million people with severe food insecurity), and~ 840 million people without access to electricity (https://www. sdgindex. org/reports/sustainable-development-report-2019/). Billions of people are suffering from water and energy insecurity. Specifically, 3 billion people lacked basic handwashing facilities at home in 2017,~ 3 billion people had no access to clean cooking fuels and technologies in 2017, and~ 4.8 billion people experienced either human water security or biodiversity threats. Among the 17 Sustainable Development Goals (SDGs) approved by the United Nations in 2015,“zero hunger”(Goal 2),“affordable and clean energy”(Goal 7), and “clean water and sanitation”(Goal 6) are specifically set for food, energy, and water, respectively, while other goals are closely linked to these three resources. Food production and processing sectors are the largest water users and important energy consumers. Quantifying the complicated interdependencies among food, energy, and water is critical to achieve the SDGs (Liu et al., 2018). The FEW nexus has a large impact on human adaptation to various grand challenges, such as climate extremes and change, population growth, and water scarcity.(Fig. 1) Considerable progress has been made on identifying the grand challenges of FEW nexus and developing new approaches to managing limited FEW resources (eg Conway et al., 2015, Liu et al., 2017). However, effective implementation of those approaches is limited by insufficient understanding of FEW nexus tradeoffs in the context of science-policystakeholder interactions (Liu et al., 2017). The lack of scientific understanding further precludes development of system-level tools for overcoming policy barriers and facilitating stakeholder acceptance (Liu et al., 2018). The assessment of FEW nexus needs to move from a linear “tree” model that emphasizes disciplinary research to a “web” model that addresses interdisciplinary complexity (Liu et al., 2019).Building upon a previous special issue on FEW Nexus (Khanna et al., 2017), this virtual special issue (VSI) calls for contributions that will include data collection, tool development, and management policies for the FEW nexus. The scope includes database development, FEW interactions and modeling at various scales, comparative analysis of FEW challenges and approaches among regions/countries, FEW linkages to climate extremes and change, and practical implications for FEW policies and sustainable development. This VSI aims to catalyze information integration, develop system modeling techniques, and explore management strategies and practices for nexus-based sustainability. The papers in the VSI should fill substantial knowledge gaps in the FEW nexus and provide a roadmap for improving life-cycle management of FEW resources. Submissions that provide innovative insights into FEW research directions are encouraged. Original research articles and review papers are invited to address the following topics:
