SOILRICE - Geochemical and ecological soil quality status in cultivated and abandoned rice paddies
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 2004. In 2006, he completed the Specialization Course of the Master in Prospecting and Evaluation of Geological Resources - Branch of Mineral Resources at the same institution. He concluded his PhD in Geosciences in 2011 at the Faculty of Sciences of the University of Porto and University of Aveiro. Between 2012 and 2019 he was a Postdoctoral fellow of Foundation for Science and Technology. He is currently a researcher at the GEOBIOTEC research unit (Department of Geosciences of the University of Aveiro). His research has been focused mainly on the areas of environmental geochemistry and biogeochemistry. To date, he has 33 publications, 71 communications in national and international conferences and a h-index of 11. He is also a reviewer of 21 journals indexed to the Journal Citation Report. He was principal investigator for 2 scientific research projects and a research team member for 11 projects. He was/is supervisor of PhD and master students. He also participated in more than 30 specialized courses and seminars, collaborated in the organization of several scientific activities or events (organization of scientific meetings; coordinator and guide of scientific dissemination activities) and in consultancy provision services.


Ruth Pereira, PhD in Biology, is since 2011 Assistant Professor at the Department of Biology of the Faculty of Sciences, University of Porto, and coordinator of the Research Group in Soil and Water Interactions: Risk assessment. Her main research interests are related with risk assessment of contaminated sites, and of new chemical substances and terrestrial ecotoxicology.
As a result of her research activity she is the author/co-author of 118 publications in international journals indexed in Science Citation Index (h-index 24), 8 papers in national journals with peer review and 8 papers published in conference proceedings. She has also participated in multiple national and international conferences. She is/was the supervisor of 6 post-doctoral students, 14 doctoral students, (8 concluded), 32 MSc students (29 concluded) and 11 internship students. Thirteen PhD students and all the Post-doctoral students awarded grants from FCT.
