How to Prevent a Catastrophic Failure of the Global Food System

There are threats that could trigger an abrupt and widespread collapse of the global food system: nuclear war or large volcanic eruptions would drastically alter sunlight, temperature, and precipitation, reducing food production by up to 90%. **Juan García**, researcher at ALLFED (Alliance to Feed the Earth in Disasters), will present "resilient food solutions": adaptations that enable the production of calories and essential nutrients when conventional agriculture fails. We will examine options such as large-scale cultivation of marine algae even during a nuclear winter, relocation of crops resilient to extreme conditions, production of food in high-tech industrial systems nearly immune to environmental and biological risks, and the mass deployment of simple greenhouses. ALLFED researches these solutions, tests them experimentally, and works to help governments develop contingency plans and technologies capable of preventing the worst food catastrophes and a potential collapse of civilization.
