Halophytes, salt-tolerant plants, have gained significant attention in recent years due to their potential for environmental restoration in saline and degraded ecosystems. The escalating impacts of climate change, land degradation, and dwindling freshwater resources necessitate innovative approaches for rehabilitating and reclaiming salt-affected lands. Halophytes possess remarkable physiological and biochemical adaptations that enable them to survive in saline environments, including ion regulation, osmotic adjustment, and efficient water utilization. Researchers have capitalized on these traits to develop strategies for enhancing soil quality, reducing salinity levels, and promoting biodiversity in affected areas. Advancements in halophyte biotechnology have led to the identification of potential candidate species for restoration efforts, along with the development of innovative cultivation and propagation techniques. Genetic and molecular studies have unveiled the underlying mechanisms responsible for halophyte salt tolerance, allowing for the engineering of crops with increased salinity resistance. Furthermore, halophytes exhibit the potential for phytoremediation of heavy metal-contaminated soils and carbon sequestration in coastal ecosystems. The establishment of halophyte-based agroforestry and phytoremediation systems can not only contribute to soil amelioration but also provide socio-economic benefits to local communities. By leveraging the natural adaptations of halophytes and integrating them into restoration strategies, we can revitalize degraded areas, mitigate soil salinity, and enhance ecosystem resilience in the face of global environmental changes. This chapter provides an overview of the key facets of halophyte biotechnology and its role in environmental restoration.
