Geological resource production constrained by regional water availability 区域水资源可用性制约地质资源生产 ▲ 作者：KAMRUL ISLAM, KEITARO MAENO, RYOSUKE YOKOI, DAMIEN GIURCO, SHIGEMI KAGAWA, SHINSUKE MURAKAMI, ET AL. ▲链接： https://www.science.org/doi/10.1126/science.adk5318 ▲摘要： 虽然全球经济需要开采地质资源，但生产对环境有重大影响，包括使用区域可用水。 研究组将区域水资源可用性作为限制因素，揭示了32种开采地质资源的全球生产能力。他们发现，目前的资源开采大大超过了区域水资源限制，特别是2010年的铜开采（当前产量的37%超过了可用的水资源容量）。将生产地点转移到水资源压力较小的地区将缓解目前超出水资源限制的情况；然而考虑到经济因素，这并不现实。 预计未来对地质资源的需求将需要大幅增加用水量。考虑水资源在地质资源生产中的限制对可持续发展至关重要。 ▲ 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. |
