Policy shock → supply-chain stress → food-system risk
What Donald Did...
The chain from power to plate, traced in one place. This site follows how political escalation and conflict around the Strait of Hormuz can move through energy, fertiliser, farm decisions and food prices — exposing who is likely to pay the price, where, and why.
Follow the chain: sourced evidence, scenario ranges, regional exposure and the people most at risk.

The question:Where does a fertiliser shock become a crop shock — and where does a crop shock become a human shock?
The Ripple Effect
How a strait becomes a food crisis
The food impact does not begin with grain ships. It begins with energy, sulphur, ammonia and fertiliser affordability. The model tracks the cascade from chokepoint disruption to field-level production risk.
Global admin-area exposure
Risk map: nutrient shortfall × yield sensitivity × food stress
Risk points identify agricultural regions where fertiliser dependence, crop sensitivity and food-security pressure combine into a sharper threat. Each selected area shows how a global supply-chain shock can become a local harvest risk.
Low Medium High Critical
Input pressure
Fertiliser and diesel price index
A clear view of how rising input costs can move faster than food prices, placing pressure on farmers before harvest losses appear.
Crop exposure
Where the nutrient shock lands
Estimated exposure by nutrient and energy pathway, showing why some crops carry far greater fertiliser-shock risk than others.
Ranked pressure points
Administrative areas most exposed in the selected scenario
The table ranks regions by a composite score using nutrient shortfall, yield-at-risk and food-stress values. It highlights where a supply-chain disruption is most likely to become an agricultural and social shock.
| Rank | Admin area | Key crops | Nutrient shortfall | Yield-at-risk | Production risk | Food-stress score |

The calculation spine
Bounded estimates, not vibes
Every local estimate is shown as an auditable path from crop area, fertiliser dependency and import exposure through to yield pressure and food stress.
Nutrient demand
D[a,c,n] = Area[a,c] × Rate[a,c,n]Crop area multiplied by N, P₂O₅ and K₂O application rates.
Effective shortfall
Shortfall = import dependency × chokepoint exposure × severity × substitution limitTransforms global supply-chain stress into country-level fertiliser constraint.
Yield-at-risk
Loss = nutrient reduction × crop sensitivity × timing factorApplies crop-specific vulnerability and planting-window timing.
Human stress
Stress = food-price pressure × poverty × import reliance × fragilitySeparates producer risk from humanitarian food-affordability risk.
Editorial line
This is what accountability looks like when the spreadsheet reaches the supermarket shelf.
The portal should not simply say “prices are up.” It should show the path: who made decisions, which chokepoints were stressed, which farming regions were exposed, which communities carried the cost, and what data proves the chain.
