Download or read book Global Water Demand Projections: Past, Present and Future written by Upali A. Amarasinghe and published by IWMI. This book was released on 2014-10-10 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: A review of global water demand projections (WDPs) show substantial over- or under-estimation. The pre-1990 WDPs, with population as the main driver of change, over-projected current water use by 20 to 130%. The post-1990 WDPs, with sophisticated modeling frameworks, show substantial underestimation under the ‘business-as-usual’ scenarios and are more downward biased under sustainable scenarios. Overall, the value of long-term country-level projections in global WDPs is inadequate for local water resource planning. To increase the accuracy and value of global WDPs, future WDPs should take into account the spatial variation and influence of rapidly changing key exogenous and endogenous drivers of water demand in different sectors across and within countries, and provide a sensitivity analysis of projections.
