Executive summary
The edition on a few pages: the abstract, the key messages, the headline finding and what each steward reads in it.
S.1Abstract
South America, as the series reads it, is two member countries (Brazil and Argentina) that share river basins, an aquifer, power links and gas supply with neighbours that are not yet members. Brazil had 212.8 million residents and Argentina 45.9 million in 20251. Their greenhouse gas emissions excluding land use were 1,299.2 and 374.3 Mt CO₂e in 20246. Low-carbon sources supplied 89% of Brazil’s electricity and 42% of Argentina’s in 20251314. The 2024 floods in Rio Grande do Sul caused BRL 88.9 billion of damage and loss16. In March 2025 about 400 mm of rain fell in eight hours on Bahía Blanca, against a previous daily record of 175 mm17. By 26 March 2024 the Americas had recorded over 3.5 million dengue cases, 83% of them in Brazil18. Forests cover 58.5% of Brazil’s land and 17.1% of Argentina’s3. This Baseline Edition fixes the 2026 reference state from sources that could be read at evidence close. Where a regional dataset could not be read, it shows as a designed empty state that names the source and the blocker. The edition decides nothing and ranks no member country.
S.2Key messages
Six readings that frame the South America baseline, and the eight questions this edition answers, each with its status and source.
Brazil emitted 1,299.2 Mt and Argentina 374.3 Mt in 2024, excluding land use. Net bases with land use are not bound.6

S.3Headline finding
ReportedEQL 4NRF-REGIONAL-SAM-2026-BASELINE-CLI-007
About 400 mm of rain fell in eight hours on Bahía Blanca on 7 March 2025, against a previous daily record of 175 mm set in 1930.
| Item | Bar, scaled to the largest value | Value |
|---|---|---|
| 7 March 2025, in eight hours, about | 400 | |
| Previous daily record, 1930 | 175 |
Source: NASA Earth Observatory image of the day17. The two values cover different time windows and are shown for scale, not as a like-for-like series.
A single storm can exceed a station record by more than twofold. Port, road, hospital and grain-export services in a coastal city then fail together, which makes flood response a question for several authorities at once17.
S.4At a glance
S.5What each steward reads in it
GCRI · KEY T
Technical Truth
The evidence supports a coupled reading of South American risk: drought, flood and heat act on water, energy and health together.
GRF · KEY M
Public Meaning
For most people risk arrives as a flood, a dry river or a dengue season.
GRA · KEY F
Capital Meaning
Readiness implications only. Insured and uninsured loss series are not bound.
NEXUS
Synthesis
The region publishes strong series on emissions, electricity and forest, and two national pledges.
S.6What this edition is, and is not
What this edition is
A baseline: the state of South America’s water, energy, food, health and biodiversity systems in 2026 read across Brazil, Argentina. It reads the shared basins and grids that no single member controls, and sets out the questions the operational series will answer.
What it is not
Not a regional risk assessment, an official warning or a rating. It decides nothing about any institution or asset. Competent authorities keep every mandate they hold, and each member’s ownership of its own edition is unaffected. It does not stand for the European Union, which is a separate subject in the series.
What comes next
Q1 2027 opens the operational series with a sealed Foundry evidence cut. Each later edition reports what changed against this baseline: new observations, source revisions, method changes, scenario updates and corrections.

South America’s risk travels through shared rivers, grids and gas
Part I describes systems and their couplings. It assesses no authority and ranks no member country.
1.1The questions this part answers
Key questions
- Where is South America’s risk concentrated, and in which systems?
- Which couplings carry shocks across member borders?
- Which capabilities hold under compound stress, and which are only documented?
- What must the 2027 programme measure first?

1.2The argument
Brazil had 212.8 million residents in 2025 and Argentina 45.9 million1. Brazil holds 82.3% of the two members’ population (ESTIMATED, Nexus arithmetic), and their GDP together was about USD 2,963 billion in 202512. This baseline reads South America as a region whose members share basins, an aquifer, power links and gas supply with neighbours, so that a shock in one reaches the others.
The forcing layer is visible in recent records. WMO reported record heat, persistent drought, accelerating glacier retreat and rising seas across Latin America and the Caribbean in 202515. Floods in Rio Grande do Sul in 2024 caused BRL 88.9 billion of damage and loss16. About 400 mm of rain fell in eight hours on Bahía Blanca on 7 March 2025, against a previous daily record of 175 mm17. The Negro River at Manaus fell to 12.66 m in October 202424.
Heat and rain add a health layer. By 26 March 2024 the Americas had over 3.5 million dengue cases, and Brazil held 83% of them18. The figure is a count of reported cases, not an estimate of burden.
The water layer rests on large stocks and uneven access. Brazil had 26,918 m³ of renewable freshwater per person in 2022 and Argentina 6,431 m³9. In 2024, 88.6% of Brazil’s population used safely managed drinking water8. The Argentine value is not bound.
The energy layer is mostly low-carbon in Brazil and mixed in Argentina. Low-carbon sources supplied 89% of Brazil’s electricity and 42% of Argentina’s in 20251314. A 2,200 MW converter at Garabí and pipelines through Bolivia connect the members2728. Binational plants on shared rivers tie hydropower to river flow41.
This edition therefore reads South America’s risk as a property of the couplings between these forces. The matrix, risk objects, capability ladder and scenario that follow ask two questions: where does a shock travel next across a border, and who holds the capability to stop it?
Low-carbon sources supplied 89% of Brazil’s electricity in 2025 and 42% of Argentina’s1314. Wind and solar supplied 27% in Brazil and 16% in Argentina. The World Bank renewable output series ends in 2021 with 77.4% for Brazil and 25.5% for Argentina5. The series use different definitions and are not directly additive.
| Item | Bar, scaled to the largest value | Value |
|---|---|---|
| Brazil, low-carbon | 89 | |
| Argentina, low-carbon | 42 | |
| Brazil, wind and solar | 27 | |
| Argentina, wind and solar | 16 |

1.3Twenty couplings between five systems
The South America matrix types the twenty couplings between the five core systems. Strengths are Nexus estimates from the cited evidence and analogue events; they set the starting graph that the Q1 2027 Foundry cut will test.
Each line is one coupling from one system to another, drawn by the strength the edition assigns. Strengths are Nexus estimates from the cited evidence and analogue events.

Key findings
Twelve findings carry the baseline. They are grouped by system, never ranked. Each resolves to its source or, where Nexus analysis is involved, to its stated method.
2.1Headline finding
ReportedEQL 4NRF-REGIONAL-SAM-2026-BASELINE-CLI-007
About 400 mm of rain fell in eight hours on Bahía Blanca on 7 March 2025, against a previous daily record of 175 mm set in 1930.
| Item | Bar, scaled to the largest value | Value |
|---|---|---|
| 7 March 2025, in eight hours, about | 400 | |
| Previous daily record, 1930 | 175 |
Source: NASA Earth Observatory image of the day17. The two values cover different time windows and are shown for scale, not as a like-for-like series.
Implication
A single storm can exceed a station record by more than twofold. Port, road, hospital and grain-export services in a coastal city then fail together, which makes flood response a question for several authorities at once17.
What would move it
Rainfall observations, flood-warning performance, the final casualty count and the insured-loss series would each move this finding. The final casualty count is not bound29.

Basin drought across the Paraná corridor and the Amazon
A conditional statement under stated assumptions, never a prediction.
5.1Assumptions
Scenario SCN-SAM-DRY-01: what is assumed, and what is held constant.
- Baseline
- the 2026 reference state in this edition
- Drivers
- a dry year with low flow on shared rivers, high power demand and delayed rains
- Analogues
- Negro River 202424; Paraná 202125; dengue in 202418
- Interventions
- none modelled, the specification describes the unmitigated case
- Run state
- narrative specification; quantified Foundry run scheduled for Q1 2027
5.2The cascade, step by step
- 1
CLI → WAT
low flows cut navigation and hydropower on shared rivers
- 2
WAT → ENE
hydropower falls and gas demand rises
no analogue bound
- 3
ENE → INF
cross-border flows through one converter and Bolivian pipelines reach their limits
- 4
WAT → FOO
barge loads and export logistics fall
Paraná 202125
- 5
CLI → HLT
heat and delayed rains raise dengue risk
dengue 202418
- 6
FIN → recovery
rebuilding slows where cover is thin
loss series not bound
5.3The scenario as a table of steps
How the shock in scenario SCN-SAM-DRY-01 would travel through South America’s coupled systems, step by step, under the assumptions the edition states.
| Step | What happens | Source |
|---|---|---|
| 01 Climate to water | Low flows cut navigation and hydropower on shared rivers. Analogue or source: rivers 2024 and 2021 [24] [25]. | Edition REG-SAM, scenario SCN-SAM-DRY-01, step 1 |
| 02 Water to energy | Hydropower falls and gas demand rises. Analogue or source: no analogue bound. | Edition REG-SAM, scenario SCN-SAM-DRY-01, step 2 |
| 03 Energy to infrastructure | Cross-border flows through one converter and Bolivian pipelines reach their limits. Analogue or source: links [27] [28]. | Edition REG-SAM, scenario SCN-SAM-DRY-01, step 3 |
| 04 Water to food | Barge loads and export logistics fall. Analogue or source: Paraná 2021 [25]. | Edition REG-SAM, scenario SCN-SAM-DRY-01, step 4 |
| 05 Climate to health | Heat and delayed rains raise dengue risk. Analogue or source: dengue 2024 [18]. | Edition REG-SAM, scenario SCN-SAM-DRY-01, step 5 |
| 06 Finance to recovery | Rebuilding slows where cover is thin. Analogue or source: loss series not bound. | Edition REG-SAM, scenario SCN-SAM-DRY-01, step 6 |

Readings from the other desks
The regional baseline is read through each steward’s lens, then once as a whole. Each lens is a projection of reviewed findings, not a separate argument. The other desks’ own editions of this subject are listed first, as cross-references, not copies.
6.1The other desks’ editions of this subject
Federation: each desk writes its own edition for the subjects in its remit. Until a desk releases, its edition shows its frame and the reading this edition printed for it.
| Desk | Edition | State | Identifier |
|---|---|---|---|
| GCRI Systems Evidence | No edition of this subject at this desk in the 2026 Baseline cycle | Not in this cycle | |
| GRF Public Deliberation | No edition of this subject at this desk in the 2026 Baseline cycle | Not in this cycle | |
| GRA Capital Readiness | Outside this desk’s remit | Not in remit | |
| Standards Progress | Outside this desk’s remit | Not in remit | |
| Academy Capability | Outside this desk’s remit | Not in remit | |
| Index Measurement | No edition of this subject at this desk in the 2026 Baseline cycle | Not in this cycle |
6.2Three lenses
One edition, read by each steward. The lens of this site comes first.
GCRI · KEY T
Technical Truth
The evidence supports a coupled reading of South American risk: drought, flood and heat act on water, energy and health together. Evidence is strongest for population, emissions and the electricity mix, and weakest for losses, river-flow series and the condition of nature.
CLI-001 · CLI-006 · WAT-008 · SYS-012
GRF · KEY M
Public Meaning
For most people risk arrives as a flood, a dry river or a dengue season. The baseline asks that public debate weigh how shared rivers and shared grids make one member’s event another’s problem.
CLI-006 · HLT-010 · ENE-003
GRA · KEY F
Capital Meaning
Readiness implications only. Insured and uninsured loss series are not bound. These show where finance-readiness evidence will matter. Nothing here is advice, a rating or an endorsement.
CLI-006 · SYS-012
NEXUS
Synthesis
The region publishes strong series on emissions, electricity and forest, and two national pledges. The 2027 programme should bind loss, river-flow and cross-border flow data, test the basin drought, and read deforestation at source.
SYS-012 · A-01 · A-02
6.3Standards, Academy and steward contributions
How the Nexus Standards drafts, the Risk Academy and the three stewards feed each quarterly edition for South America. The standards are preparatory working drafts (October 2026) and are cited as drafts, never as adopted standards.
| Quarter | Edition | Question | Boundary |
|---|---|---|---|
| Q1 | State and Agenda | What matters this year, and what is the starting position? | observed baseline stays distinct from planned work |
| Q2 | Evidence and Build | What new evidence and capability have been developed? | a configured capability is not a validated result |
| Q3 | Stress Test and Readiness | What do scenarios and tests reveal? | simulated loss or performance is not observed impact |
| Q4 | Annual Synthesis and Renewal | What did the year establish, and what changes next? | release follows review, not event publicity deadlines |

6.4GCRI reading: the model card
GCRI’s reading of this edition is its model card: what the national model is, what it computes and where it stops. It is printed in full in Annex A, with the methods it belongs to. Annex A, methodology
6.5Global Risks Forum reading: editorial essays
Four signed essays by the Reports editorial team set out the positions this edition takes. They are interpretation, labelled as such; the evidence they draw on is in the findings register.
Floods, droughts and grid faults do not stop at a frontier. The baseline treats the shared basin, the shared aquifer and the cross-border link as the units of analysis, with member countries as the places where the effects land.
EDITORIAL ESSAY · 01
Risk crosses the border first
The registry names two members for South America. Other countries on the same rivers and aquifers appear as basin states, and no edition of theirs is claimed here. Totals for Latin America and the Caribbean are a reference aggregate and are not the region.
EDITORIAL ESSAY · 02
Two members are not a continent
A hydropower-heavy system and a gas export route point the same way: security depends on diversity of sources and on control of the links, not on volume alone.
EDITORIAL ESSAY · 03
Supply security is a design question
Several data that matter most for risk, including river-flow series, plant output and losses, could not be read at evidence close. The edition shows each gap and the source that would fill it.
EDITORIAL ESSAY · 04
Gaps are findings too

Systems in depth
One section per system: its state at evidence close, its exposures and what the operational series will watch.
8.1Member countries: the baseline regional chapter
The two member countries named in the series registry, read side by side on the same indicators. Latin America and the Caribbean totals appear only as a reference aggregate. They are not the region and are not joined to it.
| Member | State at baseline | Evidence | Status |
|---|---|---|---|
| Brazil | population 212.8 million; emissions 1,299.2 Mt; low-carbon 89% of electricity; renewables 46.5% of final energy in 2021; forest 58.5%; 29.4% protected; floods in 2024 | 134671316 | Reported |
| Argentina | population 45.9 million; emissions 374.3 Mt; low-carbon 42% of electricity; renewables 9.2% in 2021; forest 17.1%; 9.7% protected; Bahía Blanca storm in 2025; safe water not bound | 134671417 | Reported |
| Latin America and the Caribbean reference aggregate | population 666.6 million; GDP USD 7,396 billion; emissions 3,510.6 Mt (not the region) | 126 | Reported |
Couplings across members
- CLI → WAT across the Paraná corridor (Brazil, Argentina and neighbours)
- ENE → ENE through the Garabí link and gas pipelines
- HLT ← CLI dengue across members and neighbours
- FIN ← CLI losses carried by insurers across borders
Evidence to bind in 2027
- net emissions with land use on one basis
- flood loss and dengue series by member
- Argentine safely managed water share
8.2Shared basins and grids: the baseline regional chapter
Shared basins, an aquifer, grids and gas supply carry risk across member borders. This chapter names each system, the members involved and the evidence read at baseline. Rows without a source are designed empty states.
| Basin | Members involved | Evidence | Status |
|---|---|---|---|
| Paraná–La Plata | Brazil and Argentina; other basin states are outside the member set; area not bound | 39 | NOT BOUND |
| Uruguay River | Argentina and Brazil on its banks; no source read | 39 | NOT BOUND |
| Amazon | Brazil; Argentina is not a basin state; Negro River low in 2024 | 2440 | Reported |
| Guarani aquifer | Brazil and Argentina among four states; area by country not bound | 21 | NOT BOUND |
| Grid | Members involved | Evidence | Status |
|---|---|---|---|
| Garabí link | rated 2,200 MW back-to-back converter between 60 Hz and 50 Hz systems; flows mainly from Brazil to Argentina | 27 | Reported |
| Itaipú and Yacyretá | binational plants on shared rivers; output not bound | 41 | NOT BOUND |
| Gas supply | first Argentine exports to Brazil through Bolivian pipelines reported in early 2026; volumes not bound | 28 | Reported |
| Gas transit volume | a figure of 3 million m³ a day was quoted for transit; not corroborated | 28 | Inferred |
| Electricity trade flows | monthly flows between the members not bound | 27 | NOT BOUND |
Couplings through shared systems
- CLI → WAT → ENE low flow into hydropower
- INF → ENE a link fault crossing borders
- TRD → ENE gas route change into power prices
- WAT → FOO navigation and irrigation
Evidence to bind in 2027
- Paraná low-water days and navigation depth
- basin area by country
- binational plant output
- monthly gas transit volumes
8.3Hub list: the baseline regional chapter
The hubs the series registry names for this region and for its member countries. The list is read from the registry, so a change there changes this page.
Registry
- Regional hubs
- São Paulo
- Desks with a remit
- GCRI · GRF · GRX
- Registry record
- NR-REGIONAL-SAM-2026-BASELINE-v1.0.0
| Hub | Member | Registry role | Member edition |
|---|---|---|---|
| São Paulo | Brazil | G20 · hub | in preparation |
| not named in the registry | Argentina | G20 | in preparation |
What a hub does in this series
- Hub terms of reference are not set at baseline
- Hub contact points are not named at baseline
- The registry names the hubs and the desks with a remit; working arrangements follow from Q1 2027
8.4Regional pathway: the baseline regional chapter
The regional pathway is the route through which the series reads South America as one region from 2027. This page states what exists today and what comes next. It does not describe any body that has not been constituted.
| Stage | What exists today | State | Next |
|---|---|---|---|
| Regional hubs | São Paulo is named in the series registry | NAMED | terms set from Q1 2027 |
| Desks | GCRI, GRF and GRX hold the remit for regional editions in the registry | NAMED | work plan for Q1 2027 |
| Evidence graph | member and regional findings share identifiers | PREPARED | first sealed cut NQ-REG-SAM-2027-Q1 |
| Member editions | Brazil in preparation; Argentina in preparation | MIXED | review through the chain before release |
Open at baseline
- Constitution of any regional council or working group
- Hub terms of reference and contact points
- Admission of further South American subjects to the registry
Decisions that rest elsewhere
- Energy, water and health policy rest with national authorities
- Treaties are made by their parties; this edition cites them and decides nothing
- Countries that share basins with the members are not members of this edition

Methodology
How the edition was made: methods, the model card, the evidence cut and its age, the acceptance record and the glossary.
A.1Methods
The regional baseline uses published values and four simple derivations. Each is shown in full so that any reader can reproduce it.
| No. | Derivation | Calculation | Result |
|---|---|---|---|
| (1) | Brazil’s share of the two members’ population, 2025 | 212.81 ÷ (212.81 + 45.85) | 82.3% |
| (2) | Brazil’s share of the two members’ emissions excluding land use, 2024 | 1,299.18 ÷ (1,299.18 + 374.34) | 77.6% |
| (3) | Brazil’s share of the two members’ GDP, 2025 | 2,279.92 ÷ (2,279.92 + 683.10) | 76.9% |
| (4) | Combined emissions excluding land use, 2024 | 1,299.18 + 374.34 | 1,673.5 Mt |
| Strength | Definition |
|---|---|
| STRONG | a disruption in the source system has historically changed the target system’s service or output within one season, in more than one region |
| MODERATE | an effect is documented but buffered or slower |
| WEAK | an effect is plausible but not documented at regional scale |
| Label | Rule |
|---|---|
| Reported | value as issued by its source, with year |
| Inferred | reasoned from cited evidence; never a measurement |
| Estimated | Nexus analytical value with stated method |
| Scenario | conditional on stated assumptions |

A.7Status words
| Status | What it means |
|---|---|
| Observed | Measured directly and published by the source. |
| Reported | Published statistics of an official or institutional source. |
| Declared | Stated by the body concerned; not independently measured. |
| Estimated | A Nexus estimate from cited evidence, with its method in Annex A. |
| Modelled | Produced by a stated model from cited inputs. |
| Inferred | Reasoned from cited evidence; not measured. |
| Forecast | A projection by the cited source. |
| Simulated | A simulation result under stated assumptions. |
| Scenario | A conditional statement under stated assumptions; never a prediction. |
| Expert input | Expert judgement, recorded with its basis. |
| Candidate | Proposed for a later edition; not yet evidence. |
| Evidence-quality levels (EQL 1 to 5) grade the source behind a value; they are not a score of the subject. | |
A.8How the edition is made, released and corrected
Every edition is built from a sealed evidence cut, reviewed under three keys, signed and deposited before any site shows it as published; corrections go to Nexus Standards as change proposals and feed the next cut.
| Step | What happens | Source |
|---|---|---|
| 01 Evidence arrives from the pillars | Foundry seals observations and indicator series, Universe hands over after-action and scenario findings, and contributions are screened at every gateway, including this site’s. | |
| 02 The cut is sealed | On the cut date the evidence is pinned under one identifier, so anyone can rebuild the edition from exactly what it was built on. | |
| 03 The edition is assembled | The edition is drafted from its template and content pack. Agents may draft; they never publish and never decide. | |
| 04 The keys turn | At the publisher of record the truth key comes first: every value is checked against its source or stated method before the meaning and capital keys turn. No edition moves on until every key has been turned by a named steward. | |
| 05 The gate opens | A named approver releases one exact digest of the edition; any change after this point is a new version, never a silent edit. | |
| 06 Signed and deposited | The PDF, the web edition and the data bundle are signed together with a manifest and an RO-Crate description, and deposited on Zenodo with a concept and a version DOI. | |
| 07 Published on its desk’s site | Only then does the edition show as published on its desk’s Reports site, and the Collection lists it as a part. | |
| 08 Corrections go to Standards | Method and correction findings go to Nexus Standards as change proposals; citations, corrections and new contributions feed the next evidence cut. |
A teaching model of the process, not a forecast and not a record of any run; dates and counts on this page come from the programme record. Sources: Reports governance at GCRI Canada (2026); Zenodo, repository of record for Reports deposits (2026).
