How a local disruption becomes a global shortage
A factory fire, a canal blockage or an export restriction can stop production on other continents, because modern economies run on long and concentrated supply networks.

Twin figures for the Tonle Sap and the Lower Mekong at Phnom Penh, counted from its layers at their stated dates.
For Supply network and economic contagion: the faculty's twin of Tonle Sap on the planet map, the globe and in 3D. Pick a generator, switch layers, run the instruments; every layer prints its provider and date.

Flat plan of the same data: the lake and rivers, the dams, the plants by capacity, the cropland and tree cover cells and the numbers below. The 3D twin opens on devices with WebGL once its data and library have been checked; discharge, vegetation, surface water and the annual land cover load in the twin on request, each with its data date.

The discipline teaches input-output models and the inoperability model that trace those dependencies, production network structure and the hidden higher-tier suppliers, inventories and the bullwhip effect, agent-based models of firms, and network robustness measured by percolation and chokepoints, with trade and financial contagion as the companion channels. Its cases include the 2021 Suez Canal blockage, the semiconductor shortage and the critical mineral export controls of 2025. A graduate can build a small input-output propagation, find a network's chokepoints and test a buffer against a disruption scenario.
This area covers how shocks propagate through production networks, trade and finance: input-output linkages, supplier concentration, inventories and the network structure that turns a local disruption into a global one. It is taught in the department of Systemic Risk and Complexity, Faculty of Systems and Nexus Studies, through courses still to be authored.
