5.1Assumptions
Scenario SCN-GS03-HRV-01: what is assumed, and what is held constant.
- Baseline
- the 2026 reference state in this edition
- Drivers
- a strong El Niño that cuts yields in several regions while fertiliser, fuel and freight costs stay high and one major export route stays constrained
- Analogues
- the 2026 Gulf and Black Sea disruptions143; the El Niño outlook8
- Interventions
- none modelled: the specification describes the unmitigated case
- Run state
- narrative specification; quantified run scheduled for 2027
5.2The cascade, step by step
- 1
ENE → FOO
fertiliser and fuel costs stay high; farmers cut input use
2026
- 2
CLI → FOO
rainfall and heat anomalies lower yields in several regions
2026
- 3
TRD → FOO
export availability falls; importers compete for other origins
2026
- 4
FOO → FIN
import bills and domestic food prices rise
2025 · 2026
- 5
FOO → HLT
diet quality falls and acute malnutrition rises in the lean season
2025
- 6
GOV → FOO
humanitarian need grows as funding falls

5.3The scenario as a table of steps
How the shock in scenario SCN-GS03-HRV-01 would travel through Global Food and Agrifood Systems‘s coupled systems, step by step, under the assumptions the edition states.
| Step | What happens | Source |
|---|---|---|
| 01 Energy to food | Fertiliser and fuel costs stay high; farmers cut input use. Analogue or source: 2026. | Edition GS-03, scenario SCN-GS03-HRV-01, step 1 |
| 02 Climate to food | Rainfall and heat anomalies lower yields in several regions. Analogue or source: 2026. | Edition GS-03, scenario SCN-GS03-HRV-01, step 2 |
| 03 Trade to food | Export availability falls; importers compete for other origins. Analogue or source: 2026. | Edition GS-03, scenario SCN-GS03-HRV-01, step 3 |
| 04 Food to finance | Import bills and domestic food prices rise. Analogue or source: 2025 · 2026. | Edition GS-03, scenario SCN-GS03-HRV-01, step 4 |
| 05 Food to health | Diet quality falls and acute malnutrition rises in the lean season. Analogue or source: 2025. | Edition GS-03, scenario SCN-GS03-HRV-01, step 5 |
| 06 Governance to food | Humanitarian need grows as funding falls. Analogue or source: 2026. | Edition GS-03, scenario SCN-GS03-HRV-01, step 6 |
