The water physical scarcity due to increasing consumption and the water economic scarcity affecting the most disadvantaged populations are increasing in many regions of the world. In a future in which water will be considered a precious and limited commodity, many scientists are investigating and developing new technologies and alternative solutions to the rising problems of water scarcity. This thesis aims to fully study the potential applications of the Atmospheric Water Harvesting Prototype in Concentrated Solar Power (CSP) plants technology. For this purpose an overview of the existing CSP plants , the most water intensive technology, is carried out with particular attention to water management and consumption.
