| Sumario: | This paper aims to highlight existing confusion over the terms used in assessments on water uses : needs, demands, supply, consumption, withdrawals. We suggest a terminological framework adapted to the challenges of water uses quantification, necessary to monitor integrated water resources management (IWRM). A state-of-the-art first draws an overview of synonyms of water use and their different interpretations. A proposal of consistent terminology is then provided based on the water use cycle concept, in order to illustrate the specificities of each term. Results show that confusions mainly arise at the water use stage itself, for which several different terms are used (need, demand, supply and consumption). Differences that distinguish these notions are described on a generic scheme of the water use cycle, where demand is the central notion. Features related to specific water uses are then presented through this cycle : drinking water, irrigation and environmental uses. A geologist, geographer, hydrologist and economist jointly conducted this reflection, thus feeding the debate on water uses’ terminology and synthesizing on what is meant by "water use" in an interdisciplinary manner. |
