## 6 Conclusions and Future Remarks  
The dramatic changes in climate conditions have severely affected several crops, making their cultivation unviable due to yield losses and the increased cost of agrochemical inputs. Therefore, new alternatives have to be invented, allowing farmers to deviate from conventional farming systems and crops. Two new promising strategies consist of the introduction of wild edible species in sustainable farming systems on the one hand and the reclamation of abandoned or degraded agricultural land on the other hand. The cultivation of halophytes as cash crops integrates these strategies and allows the cultivation of salinized soils or the use of salinized underground water in coastal areas for the production of high added value products. Sea fennel is an important halophyte with special features that fits this context. Recent case studies have shown its potential for commercial cultivation in conventional cropping systems, while the application of tailor-made agronomic practices could increase its quality and yield (Figure 5).  
However, despite the promising results, further studies are needed to establish cultivation protocols for different cultivation systems (e.g., soil or soilless systems) that will enable growers to adopt this new species. Moreover, breeding efforts are needed to valorize the great genetic variability present in the various ecotypes of the species through the selection of elite genotypes with improved quality and agronomic features. The propagation of the species is also an issue, since commercial cultivation requires high numbers of plants with uniform size and morphological traits. Therefore, in vitro propagation protocols have to be further studied and established, thus allowing for the easy production of seedlings. More studies related to the health effects of the various plant parts focusing on unraveling those mechanisms involved in bioactive effects as well as revealing the chemical compounds that are responsible for these effects are also needed. This approach will help to further improve the quality of the final product through the application of fine-tuned cultivation practices as well as through the selection of specific ecotypes. Finally, considering the current trends in the food industry and the well-established consumer needs for convenient and easy-to-cook or ready-to-cook products, the whole food chain has to be reinvented. The consumers, especially the younger ones, have to be trained to prefer healthy and functional foods, even food products with peculiar and unusual taste, while the concepts of eating locally and seasonally, which are fully in line with the introduction of wild edible species in the everyday diet, should be promoted within the context of climate crisis mitigation.
