 Wheat is a staple food crop grown around the world, requiring significant amounts of water for its cultivation. This study assessed the global water footprint of wheat production and consumption, including both direct and indirect water use. It found that the majority of the water footprint of wheat production occurs in North America, Europe, and Asia, while most of the water footprint of wheat consumption occurs in developed countries such as Japan and Italy.
