 This study aims to estimate the green, blue, and gray water footprint of wheat production and consumption globally using a high-resolution approach. The assessment is based on a grid-based dynamic water balance model that takes into account daily soil water balance and climatic conditions for each grid cell. The results show that the global average water footprint of wheat per ton of crop was 1,830 m and l t, sup and gt, 3 and l t slash sup and gt slash ton, with about 18% of the water footprint related to production meant not for domestic consumption but for export. The major portion of virtual water export comes from the USA, Canada, and Australia alone. The study also highlights the large total blue water footprint observed in the Ganges and Indus River basins, which are known for their water stress problems. Additionally, about 93% of the water footprint of wheat consumption in Japan lies in other countries, particularly the USA, Australia, and Canada. This article was authored by M. M. McConan and A. Y.
