Estarreja is a region of marked contrasts, where an almost unique ecological reservoir, the Baixo Vouga Lagunar (BVL), contrasts with one of the most important chemical industry of the country. Fortunately, these contrasts between nature and man’s hand are not always so marked. Integrated in this ecological reserve, man modelled the land and used the surface water reservoirs to develop there an agricultural practice dedicated to rice cultivation, and perfectly harmonized with the surrounding landscape – the “Bocage landscape”.
However, rice cultivation in the region of BVL (the only place in the north of Portugal where rice is cultivated) has been abandoned in the last decades. The reasons for this abandon are several, however the main one is the low paid prices for the produced rice and the unproductivity of the soils caused by saline water intrusion.
Since now some funds are being provided to encourage rice production in this region, it is important to study the actual quality status of the soil (geochemical and ecological status) in the rice paddies under cultivation and in the abandoned ones. This study is crucial not only to assess and understand the potential of this area to support this agricultural practice (in the present and in the future), but also to estimate the possible environmental impacts that may arise from rice cultivation in a protected ecological landscape like this one.

Nuno Durães finished his degree in Geology at the Faculty of Sciences of the University of Porto in 2004 and in 2006 he completed a Post-Graduation in Prospecting and Evaluation of Geological Resources - Mineral Resources in the same institution. He completed his PhD in Geosciences in 2011 by Faculty of Sciences of the University of Porto/University of Aveiro. Currently he is a postdoctoral fellow at GEOBIOTEC research center (University of Aveiro). His research has focused mainly on the geochemistry and mineralogy of the supergenic environment, environmental geochemistry and biogeochemistry. To date, he has 23 publications and 46 communications in national and international conferences. He was principal investigator of a scientific research project and a member of other 7 scientific projects.


Carla Patinha is currently a laboratory Technician and a researcher of GEOBIOTEC research unit in Department of Geosciences of University of Aveiro (Portugal). She is graduated in Geological Engineering by the University of Aveiro (1994), completed the M.Sc. degree in Geochemistry by UA in 1997, and finished her PhD degree in Geosciences by the UA in 2002.
Her present research interests include: implementing laboratory field studies on soil and crop management under saline conditions, studying geochemical records of environmental changes (climate changes and human activities), investigating the dynamics of chemicals (organic and inorganic) used in vineyards soils and their impacts on the environment.

Anabela Cachada PhD is a researcher in the area of Risk Assessment and Environmental Chemistry at University of Aveiro and University of Porto (Portugal). She has a PhD in Chemistry (University of Aveiro, Portugal), a Master in Geochemistry (University of Aveiro, Portugal), and a degree in Environmental Engineering and of the Natural Resources (University of Trás-os-Montes e Alto Douro, Portugal). She has been working during several years on soil pollution, particularly with organic contaminants. Nowadays she is particularly interested in the risk assessment of contaminated soils and in the evaluation of organic contaminants bioavailability and bioacessibility. She participated in 14 multidisciplinary research projects (including two European funded projects), related to soil pollution monitoring and with the behaviour of organic contaminants in the environment. She has 28 papers published in international scientific periodicals with referees, and she has 16 oral communications...
