Analysis on the current status of international water resources and research focuses

Using the methodology of intelligence analysis, combined with information investigation and data analysis, we studied the general situation, distribution and utilization of international water resources from both qualitative and quantitative point of view and tried to disclose the research hot-spot in this field. Among them, data used in qualitative analyses come from the annual reports and monographs of related international organizations and programs such as UN Environmental Program, Program on Water Resources of Global Environment Monitoring System and Water Environment Union. Data used for quantitative analyses come from the databases such as Web of Science，ISI Proceeding and DII. Thomson Data Analyzer, strategic intelligence analyzing platform and Aureka patented analyzing platform are utilized to reveal the current research focus in water resources studies from both literatures and patents. It has been shown that the overall amount of usable global water resource is limited and it′s unevenly distributed. Agriculture accounts for a majority proportion of the total water resources consumption. Integrated water resources management, water quality, climate change, geographic information system and irrigation are five topics which received most concerns. Membrane water processing is one of the research focuses in the field of water processing technology.
