Risk Academy, a Nexortium programmeFaculty of Systems and Nexus Studies

The scope ladder, the method cycle and the water-energy-food-ecosystems nexus

Department of Nexus-Based Risk Management

Nexus-Based Risk Management is the Academy's encompassing frame for interconnected risk, grown from the water-energy-food-ecosystems nexus.

Twin figures for the Tonle Sap and the Lower Mekong at Phnom Penh, counted from its layers at their stated dates.

Twin builder and simulator.

For Department of Nexus-Based Risk Management: 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.

The Tonle Sap and the Lower Mekong at Phnom Penh: a flat plan of the faculty twin. Terrain 0 to 1,700 m; River 2,956 km; 14 dams; 6 power plants, 88 MW; Tree cover 37.8 percent of the box; Cropland 39.9 percent of the box; Built-up 0.9 percent of the box; Permanent water 4.7 percent of the box; River discharge, GloFAS via Open-Meteo: live, loads in the twin; Vegetation index, MODIS Terra NDVI 8-day: live, loads in the twin; Surface water extent, OPERA DSWx (HLS): the flood pulse: live, loads in the twin; Land cover classes, MODIS IGBP (annual): live, loads in the twin. Contours every 250 metres from the elevation grid; named rivers by class; cropland, tree cover, water and built-up shares (esa worldcover 2021) as the class holding a quarter or more of each cell; dams as marks; power plants as marks.
The Tonle Sap and the Lower Mekong at Phnom Penh, Cambodia. 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.

What the department studies.

The department teaches the scope ladder from entity to sector, system of systems, region and planet; the eight-step method cycle from scoping and interdependency mapping through compound and cascade scenarios, systemic stress testing, options appraisal, anticipatory triggers and the governance of shared exposure to monitoring and correction; the upward flow of entity registers into the nexus layer and the downward flow of systemic notices, tolerances and scenario packs; evidence grading from not bound to validated; and the trade-offs and synergies between water, energy, food and ecosystems on basins, cities and national plans, under ISO 31000 and the Sendai Framework, which the frame nests and never replaces. On the faculty's twin the department's instrument is the loop simulator: the Tonle Sap's inflow, a reservoir you size, the turbine, the irrigated cropland WorldCover measured and the flooded lake, with every parameter on screen. A graduate can place a risk register on the scope ladder, write its dependency fields, run the method cycle on a basin and grade every finding by its evidence.
