The Ins And Outs Of Water Use -- A Review Of Multi-Region Input--Output Analysis And Water Footprints For Regional Sustainability Analysis And Policy
This paper reviews current knowledge about water footprints (WFs) and the role of input--output techniques. We first provide an overview of the prevailing ‘bottom-up’, process-based methods and their strengths and limitations. This overview leads to discussion of the benefits of combining process-based water footprints with information from input--output techniques. The central theme and proposition is that environmental multi-region input--output analysis (E-MRIO) has a powerful capacity to establish the geography of embodied water, and to complement process-based approaches to WF by expanding their supply-chain coverage. Combining process and input--output information provides valuable information for a diverse set of water planning and water policy objectives. A comprehensive and systematic outline of potential policy applications of E-MRIO (and process analysis methods) is presented.
