Geographies of Ecological Surplus explores urbanization as a process of re-organization of world ecological value, through a series of visualizations that build upon a critical instrumentalization of global geospatial datasets. Agglomeration zones, although covering no more than 3% of the earth’s surface, are directly interconnected through their bio-geographical interdependencies with the transformation of the rest of the 70% of the total land surface currently used. This other 70% mostly host landscapes of primary production: agricultural, grazing and forestry zones, sites of resource extraction and waste disposal. This project aims to shed light upon these largely invisible operational landscapes of planetary urbanization, highlighting their critical role in organizing social and ecological. A series of cartographic visualizations offers a macroscopic overview of the operationalization of the planetary terrain through the globalization of primary production, accompanied by two additional series of visualizations focusing on industrialized operations of agriculture and mining across the American continent.
