Abstract:

Humanity’s current water problems range from local-scale issues such as water supply to regional- and global-scale issues including protecting ecosystems, responding to global changes, sustaining the earth system, etc. Water resources exploitation, land utilization and climate changes have intensified pressure on water cycle through water distribution, interconnection, and virtual flows. The impact of anthropogenic pressure on water cycle has extended beyond the catchment-scale, with human activities becoming the primary driving force behind changes in regional, continental and global water cycle. Estimations by planetary boundaries framework indicated that development of global blue water and green water is approaching or beyond water planetary boundaries posing increased rising risks to earth system stabilization. Current water governance, which is focused on catchment scale and water-centric approaches, struggles to address the complexity of these issues. Governance must shift to manage not only increasing water use for economic and societal development, but also the roles and functions of water cycle in sustaining biosphere and Earth systems. Moreover, it should consider the equitable distribution of ecological services provided by water cycle. Concepts of water resilience and the economics of water as a common good enhance the conventional understanding of the water cycle, highlighting its essential role in sustain Earth systems and the cross-scale effects of human activities. Future, water resources governance is likely to evolve in three directions: from blue water management to blue-green water management, from integrated water-centric management to integrated land-water-ecosystem management, and from integrated river basin management to multi-scale management. It is critical for promoting transformation of water governance to strengthen cooperation among scientists of different fields in research of basic theory of water cycle, management policies and governance institutions.

摘要:

人类所面临的水资源问题已从起初的局部水资源供给的局域性问题,扩展到目前保护生态系统、应对全球变化、维持地球系统稳定等区域性和全球性问题。水资源开发和土地利用等经济活动与气候变化通过水流再分配、远程耦合和虚拟水流动等机制作用于水循环过程,人类活动对水循环的作用已经超出了流域尺度,成为区域尺度、大陆尺度和全球尺度水循环变化的主要驱动力。行星边界方法评估结果表明,全球蓝水和绿水开发已经接近或超过水行星边界,其引发的地球系统风险正在上升。但是,现行的水资源治理仍停留在以流域为单元、以水为中心的管理方式,越来越难以适应当前水问题的复杂性,水资源治理理念与方式亟需根本性转变。水资源治理既要考虑满足经济社会发展不断增长的用水需要,又要考虑水循环在维持生物圈和地球系统稳定运行中的作用和功能,还要顾及不同国家或地区能够公平地分享由水循环所提供或维持的公共服务。水循环系统韧性以及共有水资源经济学等理念突破了对水循环的传统认识,揭示了水循环在地球系统中的功能性和人类活动影响的跨尺度性的内在特征,正在成为引导水资源治理转型的思维方法。未来水资源治理可能会向着3个方向转型:从蓝水管理转向蓝水绿水管理,从水资源综合管理转向水土资源与生态系统综合管理,从流域综合管理转向多空间尺度综合管理。不同领域学者合作加强水循环基础理论、管控政策和管理机制研究,对于促进水资源治理转型至关重要。
