Geological resource production constrained by regional water availability 區(qū)域水資源可用性制約地質資源生產 ▲ 作者：KAMRUL ISLAM, KEITARO MAENO, RYOSUKE YOKOI, DAMIEN GIURCO, SHIGEMI KAGAWA, SHINSUKE MURAKAMI, ET AL. ▲鏈接： https://www.science.org/doi/10.1126/science.adk5318 ▲摘要： 雖然全球經濟需要開采地質資源，但生產對環(huán)境有重大影響，包括使用區(qū)域可用水。 研究組將區(qū)域水資源可用性作為限制因素，揭示了32種開采地質資源的全球生產能力。他們發(fā)現(xiàn)，目前的資源開采大大超過了區(qū)域水資源限制，特別是2010年的銅開采（當前產量的37%超過了可用的水資源容量）。將生產地點轉移到水資源壓力較小的地區(qū)將緩解目前超出水資源限制的情況；然而考慮到經濟因素，這并不現(xiàn)實。 預計未來對地質資源的需求將需要大幅增加用水量�？紤]水資源在地質資源生產中的限制對可持續(xù)發(fā)展至關重要。 ▲ Abstract： Although the global economy requires geological resource mining, production has substantial environmental impacts, including the use of regional available water. In this study, we shed light on the global production capacity of 32 mined geological resources, considering regional water availability as a constraint. We found that current resource mining greatly exceeds regional water constraints for several, notably copper (37% of current production exceeds available water capacity) in 2010. Changing the location of production to regions of lower water stress would alleviate current exceedances of water constraints; however, considering economic factors shows that this is not always feasible. Future demand for geological resources is expected to require a considerable increase in water consumption. Considering the constraints of water resources in geological resource production is crucial for sustainability. |
