A Scientific Review of the Global Water System

全球环境研究的重要新见解之一是认识到全球水系统的存在。这一概念扩展了长期接受的全球物理水循环概念，包括生物地球化学、生态和社会经济成分。全球主要研究机构最近启动了全球水系统项目（GWSP），这是科学界发出的一个强烈信号，即有关该系统的关键问题需要紧急研究。这个为期一年的项目的目标是通过汇编和评价现有的科学文献和数据库以及与科学专家进行讨论，对全球水系统的概念进行科学审查。该综述将确定尚未解决的关键研究问题。科学审查将分为三个部分(1)描述全球水系统的物理、生物地球化学、生态和社会政治方面，(2)阐述全球水系统的交叉联系，(3)确定主要的未解决的问题和研究重点。为了确保发展中国家的观点也被考虑在内，Antragssteiler建议在12个月的项目中花6个月的时间在班加罗尔的国家高等研究所。这将是一个完全独立的（eigenständiges）和独立的项目，在GWSP的框架内进行（Antragssteiler是联合主席）。预计这项科学审查将对今后几年确定全球水研究的优先事项作出重大贡献。

One of the important new insights of global environmental research has been the recognition of the existence of a global water system . This concept expands the long-accepted concept of the global physical water cycle to encompass biogeochemical, ecological and socioeconomic components. The recent launching of the Global Water System Project (GWSP) by the major global research organizations is a strong signal from the scientific community that key questions about this system need to be urgently studied. The objective of this one year project is to conduct a scientific review of the concept of the global water system by compiling and evaluating existing scientific literature and data bases and carrying out discussions with scientific experts. The review will identify key unresolved research questions. The scientific review will be divided into three parts (I) Describing the physical, biogeochemical, ecological and socio-political aspects of the global water system, (II) Elaborating cross-cutting linkages in the global water system, (III) Identifying major unresolved questions & research priorities. To ensure that the perspectives of developing countries are also taken into account, the Antragssteiler proposes to spend 6 months out of the 12-month project at the National Institute of Advanced Studies in Bangalore. This will be a fully independent (eigenständiges) and alone-standing project conducted within the framework of the GWSP (of which the Antragssteiler is Co-Chair). It is expected that the scientific review will make a major contribution to setting priorities in global water research over the coming years.
