Global Grain Shock: Food Security & Geopolitics

Global food security rests on a small number of countries producing far more grain than they consume, and shipping the surplus to countries that cannot grow enough themselves. This simulation models that trade network: pick an exporting nation, apply a drought, a conflict, or a government export ban, and watch trade routes thin out, the global price index climb, and the food security of the most import-dependent nations erode in real time — a single shock in one country reverberating across the whole system.
