The GLU Model (Global Land Use Model) based on data from the FAO explores the potentials to feed the growing population and its change of diet. It looks at the effects on deforestation and the use of biotic resource and their implications on climate change. The model was developed with Ecologic Institute to explore the potentials for biotic resource to substitute concrete and steel. Bottom line: ceteris paribus we won’t be able to feed the world. With orchestrated changes we could even feed it from organic farming with afforestation to capture CO2.
