TL;DR: In this paper, the authors provide examples from the last fifty years of scientific and technological innovations that provide relatively easy, quick and affordable means of addressing key water management issues, including virtual water trade, the silent revolution for beneficial use of groundwater, salt water desalination, and the use of remote sensing and geographic information systems (GIS).
Abstract: This paper provides examples from the last fifty years of scientific and technological innovations that provide relatively easy, quick and affordable means of addressing key water management issues. Scientific knowledge and technological innovation can help open up previously closed decision-making systems. Four of these tools are discussed in this paper: a) the opportunities afforded by virtual water trade; b) the silent revolution for beneficial use of groundwater; c) salt water desalination; and finally, d) the use of remote sensing and geographic information systems (GIS). Together these advances are changing the options available to address water and food security that have been predominant for centuries in the minds of most water decision-makers.

TL;DR: Zhang et al. as mentioned in this paper calculated the changing trend of virtual water (VW) flow related to grain transfer in China, for which three primary crops of China, including rice, wheat and maize, were considered.

TL;DR: The authors examines how three epistemic communities have each built their science by promoting very specific understandings of what is a water crisis, and how these understandings affect scientists' perceptions of which power structures legitimately carry out water management, their capacity to ask questions and the manner they formulate them.
Abstract: Various definitions of water crises emerge from epistemic communities deploying a great disparity of methodologies and fundamental hypotheses. Scientists' perceptions of which power structures legitimately carry out water management affect their definition of a crisis, their capacity to ask questions and the manner they formulate them. This determines the stakes and the actors they can observe or the scale of analysis they find relevant. This leads some to recommend a ‘solution’ that appears to be a disaster to others. This article examines how three epistemic communities have each built their science by promoting very specific understandings of what is a water crisis. Proponents of the ‘global water crisis’ spawned Integrated Water Resources Management while proponents of the ‘municipal water crisis’ locked the perception of water equity within the Millennium Development Goals. Researchers on small-scale irrigation and property regimes have often disagreed with such recommendations, often presented as in...

TL;DR: In this article, the authors applied an integrated multi-regional input-output (MRIO) hydro-economic model combined with the water scarcity index to analyze consumption water footprint (WF) and embedded or virtual water flows in interregional trade in the Haihe River Basin (HRB) and their impacts on hydrosystems.
