Water exports involve exporting freshwater from one country to another. Large increases in human population and economic growth throughout the world during the twentieth century placed a huge stress on the world’s freshwater resources. Combined with climate change, they will place an even greater demand on water resources in this century. Water shortages have become an international concern, and freshwater has been described as “blue gold” and “the oil of the 21st Century.”
