Baixo Vouga Lagunar (BVL) is an area with a strong and balanced relationship between man, land and water, recognized by its high biological diversity. However, the impact of human activity (e.g. changes in the system hydrology) combined with climate change (e.g. sea level rise), have already affected BVL, wherein areas are currently flooded by tides, and soils affected by surface saline intrusion. The conclusion of the dike, foreseen in a short term, is fundamental to save still existing agricultural areas and to reclaim flooded areas. However, it is necessary to remediate these soils from salt contamination in order to return them back to agriculture. In this context, we propose to conduct an innovative and multidisciplinary project, linking the team scientific knowledge on agriculture and soils, environmental chemistry and salt marsh ecology, in combination with local farmer’s knowledge. This proposal will integrate two of the topics proposed by OHM-Estarreja: Evolution of the Relations Between Society and Environment and Evolution of Biodiversity. We propose, to evaluate the potential of the autochthonous halophyte Salicornia ramosissima to remediate the BVL salt contaminated soils. Apart from having a phytoremediation capacity, S. ramosissima is currently considered a gourmet plant with high market demand as a green fashionable vegetable, dished up in fine restaurants all over the world. Hence, it can be grown as a cash crop and be an alternative in salinized soils for farmers in the region. RESTORE project can also serve as showcase for other coastal areas under treat due to salt contamination.
