چکیده
Water is an essential resource for social and economic development. The availability of this constantly threatened by the rapid increase in its demand. This research assesses current (2010–2016), short- (2017–2040), middle- (2041–2070), long-term (2071–2099) levels water security considering socio-economic climate change scenarios using Evaluation Planning System (WEAP) Vilcanota-Urubamba (VUB) catchment. streamflow data Pisac hydrometric station were used to calibrate (1987–2006) validate (2007–2016) WEAP Model applied VUB region. Nash Sutcliffe efficiency values 0.60 0.84 calibration validation, respectively. Different generated factors (population growth increased irrigation efficiency) impact evaluate their effect on supply system. results reveal that much higher than demand period (2010–2016). For short-, long term, two considered, “Scenario 1” (RCP 4.5) 2” 8.5). Climate show will increase. However, not cover future demands all sub-basins because evenly distributed VUB. In both scenarios, unmet was detected from 2050. 2071–2099, 477 hm3/year 446 estimated. Because population agricultural are highest, effects reducing rate improving structure simulated. Therefore, more 3” 4.5 with management) 4” 8.5 management). management proved be effective up 50% 2071–2099.
