Abstract: Research on biosaline agriculture has been increasing worldwide in recent years. In this respect, the Iberian halophyte diversity present a high-value ecological solution to be implemented for biosaline-based agroecosystems. The research on these halophytic species has been increasing worldwide and, in the recent years, especially in terms saline agriculture adaptation, osmophysiology and nutraceutical potential, highlighting the importance and potential of these species in terms of agrosolutions. The Mediterranean area has high biodiversity in terms of endemic halophytic vegetation (ca. 62 species), providing an alternative pool of potential new agricultural products to be cultivated in adverse conditions. Besides being highly diverse, most of these species are endemic and present a perennial life cycle with several applications in terms of food, forage, nutraceutical, feedstock and remediation. More specifically, the Iberian halophytic flora shows potential as resources of essential fatty acids, minerals and antioxidants—all very important for human and animal nutrition. Alongside the establishment of halophyte agroecological solutions is the provision of key ecosystem services, such as carbon sequestration and soil rehabilitation. Moreover, halophyte-based ecosystems provide additional recognized ecosystem services, beyond the final product production, by improving soil health, ecosystem biodiversity and storing large amounts of carbon, thereby increasing the ecosystem resilience to climate change and offering a green solution against climate change.
