The growing need for alternative water resources for irrigation has led to advanced technological developments, which are addressing some of the challenges that our planet is facing regarding the water supply. The Canary Islands Archipelago (Spain) is a singular territory with several years of desalination experience while using desalinated seawater (DSW) for agricultural purposes. The current paper will address the conducted research of one of the case studies done into the Horizon 2020 project MAGIC, with the aim of analyzing the use of DSW for crop production in the Southeast of Gran Canaria Island. A methodology of surveying farmers in the area has been put in practice, as well as an assessment of potential soil degradation risks that are related to DSW irrigation (with fifteen years of DSW data). Additionally, local good practices to improve the DSW quality for irrigation are discussed. This study demonstrates an excellent endorsement of the surveyed farmers in the studied area regarding the use of DSW for irrigation: the strategy of combining this type of water with other water resources, such as groundwater and/or reclaimed water is very frequent and it can guarantee water and food security in the island’s territory.
