 This research examines the global water footprints of various crops and countries, as well as the impact of international trade on water use. It found that most countries rely heavily on green water for their agriculture, while some countries import large amounts of blue water from other countries. This highlights the importance of understanding how much water is being used by different countries and how it is being sourced. Additionally, the research showed that international trade can save water and land resources, but only if the water used to produce goods is taken into account. This article was authored by M.
