5.1Assumptions

Scenario SCN-SR01-BBF-01: what is assumed, and what is held constant.

Baseline
the 2026 reference state in this edition
Drivers
heat and drought across two or more major grain-exporting regions in one season, while gas and fertiliser prices spike
Analogues
2007–2008 and 2010–2011 food price spikes; 2022 energy and fertiliser shock
Interventions
none modelled, the specification describes the unmitigated case
Run state
narrative specification; quantified run scheduled for 202723

5.2The cascade, step by step

  1. 1

    CLI → FOO

    heat and drought cut yields in several exporters at once

    2010 · 2012

  2. 2

    ENE → FOO

    fertiliser and fuel costs raise production costs

    2022

  3. 3

    FOO → TRD

    export restrictions amplify the price rise

    2008 · 2011

  4. 4

    TRD → HLT

    food-price rises cut diets in import-dependent households

    2008

  5. 5

    FIN → sovereigns

    import bills and subsidies widen deficits

    2022

  6. 6

    HLT → development

    hunger and displacement rise in fragile settings

    2011

5.3The scenario as a table of steps

How the shock in scenario SCN-SR01-BBF-01 would travel through Global Polycrisis‘s coupled systems, step by step, under the assumptions the edition states.
