From Foundry evidence to the series.
The evidence, step by step, from the 系统 this area reads to the series it feeds.
How Food Nexus reaches 报告: what it reads, how it reads it, the sealed cut and the series it feeds.
| 步骤 | 发生的事项 | 来源 |
|---|---|---|
| 01 What it reads | Food Nexus reads NXS-EOP（地球观测与数字孪生） and The Global Risks Index (NXS-GRX): governed sources with their releases, never a value without its source. | |
| 02 How it reads them | Agricultural, soil and food science and Ecology and biodiversity science turn the evidence into findings, with assumptions and limits stated beside each value. | |
| 03 The cut is sealed | Each quarter the evidence is sealed in one cut, so OBSERVED, REPORTED and ESTIMATED values stay apart and every edition can be rebuilt. | |
| 04 The series it feeds | The cut feeds Global Sector Risk and Resilience and Country Systems Risk and Resilience, from the Baseline Edition 2026 into the quarterly series. | |
| 05 Who decides | Decisions stay with the authorities that hold them, under their own rules; an edition informs a decision and never makes it. |
A teaching model of the evidence path, not a forecast and not a record of any run; the systems, methods and series named come from the registries. Sources: Reports 中的 Food Nexus (2026); Food Nexus home (2026).
The series it feeds, and what backs each.
| 系列 | Foundry systems it draws on | Academy disciplines | Series home |
|---|---|---|---|
| 全球部门风险与韧性 | NXS-GRX one sector’s structure, dependencies and concentration measures NXS-EOP observed change in the sector’s assets and their surroundings | 贸易、供应链与地缘经济 关键基础设施 and lifelines | Global Sector Risk and Resilience series home |
| 国家 系统 Risk and Resilience | NXS-GRX one country’s dependency map and its indicator baselines NXS-CMD (integrated posture and executive synthesis) the national portfolio of risk reduction work the edition reads against NXS-EOP exposure and change layers at subnational detail | 基于 Nexus 的风险管理（NRM） 灾害 风险 关键基础设施与生命线 | Country Systems Risk and Resilience series home |
| 证据简报 | NXS-GRX the evidence behind one question, with its strength and gaps NXS-POR（公共、客户和伙伴交付） the public-safe release of a brief and its corrections NXS-DSS（决策案例与审议） what the evidence settles for the decision in hand | 研究、证据与科学政策衔接 风险沟通 and risk literacy 不确定性与决策 | Evidence Brief series home |

Mirrors and harvest
The DOI is canonical. At release each signed bundle is also given an IPFS content identifier and a bloxberg anchor as mirrors; both are listed in the record once they exist. Zenodo exposes every record over OAI-PMH, and reviews and endorsements can arrive through COAR Notify where the repository supports it.
