03In the editions
9 findings of the drafted editions that bear on Water Nexus.
Drawn from the Baseline Edition 2026 drafts through the 系统 this area reads. Each opens at its anchor in its edition, with its numbered sources.
- ARE阿拉伯联合酋长国Net greenhouse-gas emissions were 195.2 Mt CO₂e in 2022 including land use, 0.8% below 2019; energy gave 164.1 Mt, industrial processes 29.6 Mt and waste 5.6 Mt, and land use removed 6.6 Mt.REPORTED · COUNTRY-ARE-CLI-001
- ARG阿根廷The national inventory reports 400.9 MtCO₂e including land use for 2022, and 377.8 MtCO₂e net on the climate-contribution basis.REPORTED · COUNTRY-ARG-CLI-001
- AU非洲联盟In 2024, 55.1% of people in Sub-Saharan Africa had electricity, up from 46.4% in 2018; about 579 million had none (derived).REPORTED · COUNTRY-AU-ENE-002
- AUS澳大利亚Greenhouse-gas emissions excluding land use were 591.5 Mt CO₂e in 2024, against 605.2 Mt in 2019 and 579.5 Mt in 2020.REPORTED · COUNTRY-AUS-CLI-001
- BRA巴西Gross greenhouse-gas emissions fell 16.7% in 2024 to 2,145 Mt CO₂e, led by lower land-use change; net emissions were 1.49 Gt CO₂e. SEEG is a civil-society estimate, not the official inventory.REPORTED · COUNTRY-BRA-CLI-001
- CHE瑞士Greenhouse-gas emissions were 40.1 MtCO₂e in 2024, 27.3% below 1990 and 22.3% below when land use is included; transport emitted 13.4 MtCO₂e and international aviation and maritime a further 5.5 MtCO₂e outside the 2030 target.REPORTED · COUNTRY-CHE-CLI-001
- CHN中国The national mean temperature was 10.9 °C in 2025, 1.0 °C above the 1991 to 2020 normal and tied with 2024 as the highest since 1951; hot days averaged 16.5, the most since 1961.REPORTED · COUNTRY-CHN-CLI-001
- EU欧洲联盟Net domestic greenhouse-gas emissions were 40% below 1990 in 2024 and 3% below 2023; on the 2030 target basis the cut was 37%.REPORTED · COUNTRY-EU-CLI-001
- GS-02全球能源Global energy demand grew 1.3% (8 EJ) in 2025, down from 2% in 2024, and electricity demand grew nearly 3%, more than twice as fast.REPORTED · SECTOR-ENERGY-GLOBAL-ENE-001
04Evidence path
From Foundry evidence to the series.
The evidence, step by step, from the 系统 this area reads to the series it feeds.
How Water 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 | Water 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 | Hydrology and water science and Water and environmental engineering 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 Water Nexus (2026); Water Nexus home (2026).
05系列
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 |
| 观测站信号 | NXS-OPS（仪器、传感器与校准） calibrated primary observations and their uncertainty budgets NXS-EWS（多重危害监测与预警） whether an anomaly was forecast and how well NXS-EOP observational change products that corroborate a signal NXS-SIG spectrum and timing anomalies that affect dependent services | 地理空间分析、地球观测与 GeoAI 气候科学、变率与变化 空间系统、空间天气与导航 | Observatory Signal 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.
