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.

Olga Ameixa is a PhD in Ecosystem Biology (2011), University of South Bohemia, CZ. Her background includes a degree in Agronomic Engineering (2003), and a MSc in Sustainable Agriculture (2007), University of Algarve, PT. She holds a professional qualification in Organic farming (from IDRHa, PT), and worked as a farmer’s advisor for 2 agricultural organizations.
In the past she worked simultaneously as a researcher in the Dep. of Biology, Univ. of South Bohemia, and in the Global Change Research Center, CZ, where she participated in several national and international projects such as: BEPAR, EuroVOL and AGRIPOPES (an ESF-funded network of 12 research teams across Europe, which used European agroecosystems as models). She made internships in the Laboratory of Agro-Ecology (ENFA) in Toulouse, FR and in Wageningen UR Greenhouse Horticulture, NL. Back in Portugal, she worked as Invited Assistant Professor (2016/17) at Dbio-UA.
Currently, she is a Researcher in CESAM & Dbio, UA, PT. Here, she worked on the EU-project LAGOONS, which aimed to understand land-sea processes and science-policy-stakeholder interface and which covered BVL area. She is the PI of RESTORE – Phytoremediation of Saline soils (CNRS/OHMI) and team member of MARSH-C-LEVEL (CNRS/OHMI). Presently, she is the PI of the FCT project SUShI (costal insect diversity). She has authored/co-authored 15 ISI-indexed papers (h-index=7; Citations: 112), 5 book-chapters and 21 communications. She is an expert and monitor of EU REA projects, Portuguese Innovation Agency (ANI) and FCT. see detailed CV: www.cesam.ua.pt/olga.ameixa. Her research interests involve the use of several nature-based solutions, including phytoremediation.


Ricardo Calado, born in 1976, graduated in Biology in 1999 and obtained his PhD in 2005 in Animal Biology from the Univ. of Lisbon. He is Principal Researcher at the Dep. of Biology (dbio) and the Associated Laboratory CESAM of Univ. of Aveiro (UA) and develops independent research on Applied Marine Ecology, Sustainable Aquaculture and Marine Biotechnology (this position is financed by FCT).
