Republic of Korea 2026
République de Corée
The Republic of Korea (대한민국) enters 2027 as a high-income economy of 51.68 million people and about US$1.87 trillion of output in 2025, with one of the lowest fertility rates in the world and an ageing society. Births rose 6.7% in 2025 to about 254,300, yet total fertility stood at 0.63 in Seoul and 1.09 in Jeonnam.

01 · Readings
Republic of Korea in six readings.
Six readings that frame the Republic of Korea baseline, and the eight questions this edition answers, each with its status and source.
02 · Sectors
Six sectors, one hexagon.
Water first, then Energy, Infrastructure, Food, Health and Biodiversity. Each count is the findings of this edition in that sector: coverage of the evidence, never a score. Infrastructure is not assessed: the edition holds no Infrastructure finding and its coupling matrix does not assess it.
- WATEau1 finding
Not bound Water supply and water-loss indicators, none. ·Not bound
Supply, loss and drought indicators not bound; pipes and basins to be read in 2027.
- ENEÉnergie1 finding
40% Low-carbon share of electricity, 2025. □Déclaré
Fossil fuels 60% of electricity in 2025; low-carbon 40%.
- INFinfrastructuresnot assessed
Dense urban networks; condition not bound at public-safe resolution.
- FOOAlimentation1 finding
16.7 million t Cereal imports expected, marketing year 2026/27, 2026. □Déclaré
Cereal imports of 16.7 million tonnes expected in 2026/27.
- HLTSanté3 findings
0.63 births per woman Lowest regional total fertility rate, 2025. □Déclaré
Births up 6.7% in 2025; fertility lowest in Seoul; ageing share not bound.
- BIOBiodiversité1 finding
Not bound Protected-area coverage, none. ·Not bound
Protected-area coverage not bound.
Outside the six sectors: Climate forcing 2, Finance 1, SEI 1, Systemic 1.
03 · Hazard exposure
The hazards this edition reads.
The edition’s own risk objects, in its order, each read across driver, exposure, vulnerability, capacity, cascade and horizon. The hexagon marks the sectors the cascade reaches; the domain beside each is an editorial reading of its hazard words.

Scenario · SCN-KOR-HRT-01
Heat and heavy-rain sequence over the capital region
Under this scenario, results describe a conditional season under stated assumptions. It is not a forecast, and no intervention described here has been carried out.

- 1CLI → ENEcooling demand lifts peak load
- 2CLI → HLTheat illness loads clinics and care settings
- 3CLI → WATheavy rain floods streets and basements

- 5INF → HLTaccess to care falls for older residents
- 6HLT → populationrecovery load falls on the same services
04 · Couplings
How the sectors carry risk into each other.
The Republic of Korea matrix types the twenty couplings between the five core systèmes. Strengths are Nexus estimates from the cited evidence and analogue events; they set the starting graph that the Q1 2027 Foundry cut will test.
| De | WAT | ENE | FOO | HLT | BIO |
|---|---|---|---|---|---|
| WAT | · | Strong | Strong | Modérée | Strong |
| ENE | Modérée | · | Strong | Strong | Modérée |
| FOO | Modérée | Weak | · | Strong | Strong |
| HLT | Weak | Weak | Modérée | · | Weak |
| BIO | Strong | Modérée | Strong | Modérée | · |
Water: 4 couplings out, 4 in; Energy: 4 couplings out, 4 in; Food: 4 couplings out, 4 in; Health: 4 couplings out, 4 in; Biodiversity: 4 couplings out, 4 in. Infrastructure is not in the coupling matrix: none of the edition matrices types it, so it carries no value.
