— Analysis of economic systems from a biophysical perspective, considering energy, resources, and ecological limits. —
Tad Patzek identifies water, food biomass, and construction materials as the three most critical material fluxes sustaining human civilization. Annually, 4,000 cubic kilometers of fresh water are withdrawn, with agriculture accounting for 70% of this volume. Concurrently, global agriculture yields 1
A framework built on two intersecting axes — whether the global economy grows or contracts from current levels of energy throughput, and whether that trajectory moves toward or further into ecological overshoot — generates four distinct directional scenarios: Green Growth, in which expansion couples

Balázs Matics identifies a critical divergence that occurred around 2015, where the production of new oil barrels ceased to correlate directly with diesel output. This breakdown emerged as conventional, diesel-rich crude oil sources plateaued, forcing a greater reliance on lighter, less dense unconv
The invention of synthetic nitrogen fertilizer through the Haber-Bosch process in the early twentieth century offers one of history's clearest demonstrations of how technology expands the throughput of resource extraction without revealing its long-run price. Crop yields exploded, human population f
