一句话总结

论文提出一个全球食品系统指标框架，跨五个主题建立基线，利用最新数据跟踪向2030年的转型。

ABSTRACT

Transforming food systems is essential to bring about a healthier, equitable, sustainable, and resilient future, including achieving global development and sustainability goals. To date, no comprehensive framework exists to track food systems transformation and their contributions to global goals. In 2021, the Food Systems Countdown to 2030 Initiative (FSCI) articulated an architecture to monitor food systems across five themes: 1 diets, nutrition, and health; 2 environment, natural resources, and production; 3 livelihoods, poverty, and equity; 4 governance; and 5 resilience and sustainability. Each theme comprises three-to-five indicator domains. This paper builds on that architecture, presenting the inclusive, consultative process used to select indicators and an application of the indicator framework using the latest available data, constructing the first global food systems baseline to track transformation. While data are available to cover most themes and domains, critical indicator gaps exist such as off-farm livelihoods, food loss and waste, and governance. Baseline results demonstrate every region or country can claim positive outcomes in some parts of food systems, but none are optimal across all domains, and some indicators are independent of national income. These results underscore the need for dedicated monitoring and transformation agendas specific to food systems. Tracking these indicators to 2030 and beyond will allow for data-driven food systems governance at all scales and increase accountability for urgently needed progress toward achieving global goals.

研究动机与目标

• 呈现食品系统倒计时至2030（FSCI）框架与指标体系。
• 展示用于全球食品系统监测的包容性指标筛选过程。
• 在可获得数据基础上构建首个全球基线，以追踪食品系统转型。
• 识别数据缺口与进展在区域间的变异性。
• 强调实现全球目标需要专门的监测与治理机制。

提出的方法

• 描述五主题架构：饮食、营养与健康；环境、自然资源与生产；生计、贫困与公平；治理；韧性与可持续性。
• 在每一主题内定义指标领域（每主题三至五个）。
• 将指标框架应用于最新可用数据以构建全球基线。
• 通过包容性、协商式过程选择指标。
• 评估数据覆盖范围并识别关键缺口，如非在岗生计、粮食损失与浪费、治理等。

实验结果

研究问题

• RQ1 哪些指标在五个食品系统主题中最好地捕捉进展与转型？
• RQ2 当前数据在全球、区域和国家层面覆盖拟议的指标领域的程度如何？
• RQ3 哪些主要数据缺口阻碍对食品系统转型的全面监测？
• RQ4 所构建的全球基线是否能揭示某些领域表现良好而其他领域存在不足的区域？
• RQ5 跟踪这些指标如何支持数据驱动的治理与对2030目标的问责？

主要发现

• 创建了一个框架和基线以监测全球食品系统向2030年的转型。
• 大多数主题与领域已有数据，但在非在岗生计、粮食损失与浪费、治理等关键领域仍存在缺口。
• 每个区域或国家在某些领域表现积极，但没有一个在所有领域都达到最佳状态。
• 某些指标与国家收入水平无关，强调需要超越收入水平的专门转型议程。
• 追踪到2030年的指标可以支持治理与问责，以实现全球目标。
