With rapidly increasing urbanization, a substantial portion of global freshwater is used for the manufacture of construction materials, such as steel and cement. This threatens to intensify competition over the allocation of blue water (from lakes, rivers and aquifers). However, much less attention has been paid to the virtual water content of materials, and the water–materials nexus.

解决材料制造用水过多问题

随着城市化进程的迅速发展，全球很大一部分淡水被用于制造钢铁和水泥等建筑材料。这可能会加剧对蓝水（来自湖泊、河流和含水层）分配的竞争。然而，人们对材料的虚拟水含量以及水与材料的关系的关注却少得多。
