Increasing water scarcity in arid and semiarid regions is driving the demand for non-conventional sources in irrigated agriculture. Seawater desalination for sustaining agricultural production is being as an alternative water source in some Mediterranean countries. It represents an abundant and steady source which effectively removes the climatological and hydrological constraints. However, first are highlighting that certain important issues can become a barrier to its spread for crop irrigation. high-energy requirement is still an essential feature of seawater desalination, leading to production costs times higher than other agricultural water sources. Moreover, the high greenhouse gas emissions linked intensive use of energy could exacerbate climate change. Additionally, there are important agronomic related to the lack of desalinated seawater quality standards; which can cause risks for both crop the soil environment if not properly managed. Specific quality regulations for desalinated seawater blending and management modelling, on-farm technical means and water and soil monitoring may these risks for crop irrigation. This paper reviews current irrigation experiences with desalinated analyses the most important questions to be considered, with a particular focus on the agronomical (C) 2015 Elsevier B.V. All rights
