Design/methodology/approach – This paper is supported by works (papers and scientific projects being developed) produced in Portugal and Brazil, by researchers from different areas of expertise. Findings – These two coastal zones have a similar geomorphologic evolution, due to the fact that both appeared because of a sandy spit, which started to grow and separated these areas from the sea, converting them into sheltered coasts. It was because they are protected that these two study cases early became targets for human occupation. The anthropic impacts in the systems were sustainable until the middle of the twentieth century. Since then, however, the economic development options, based first in industry and second in tourism exploration, have compromised the natural healthy balance.
Practical implications – This paper could be a contribution to a scientific support for political decisions on the coastal zone management (namely in these studied areas).
Social implications – The paper provides and increases the knowledge of the coastal zones’ evolution and occupation – from a multidisciplinary perspective – produced and made available to scientists, local politicians, students and local populations.
Originality/value – The paper provides a truly interdisciplinary approach, which allows a better understanding of the evolution of these two systems, discussing the causes and consequences of human activities in both coastal areas.

O Homem e o Litoral: Transformações na paisagem ao longo do tempo, 2017

Se as sociedades autóctones, embora com menor expressão, impactavam o meio ambiente, tal situação foi intensificada após a chegada dos europeus. Com este estudo pretende-se analisar as diferentes fases de fixação populacional nesse trecho litorâneo e a sua concomitante antropização, desde o século XVI até à atualidade. Objetiva-se traçar um panorama sobre quais os impactos antrópicos mais significativos cometidos nos ecossistemas litorâneos, procurando-se entender os diferentes ciclos de interesses económicos que o motivaram.
Palavras-chave: Rio de Janeiro; Interações Homem-Meio; Sistemas litorâneos; Impactos antrópicos.
The coast of the Rio de Janeiro state, has suffered intense transformations in its landscape.Although the autochthonous societies, with less expression, impacted the environment, this situation was intensified after the arrival of the Europeans. Through this study it’s intended to analyze the different phases of population settlement in this coastal stretch and its related anthropic actions. The objective is to provide an overview of the most significant anthropic impacts in the coastal ecosystems from the 16th century until present, trying to understand the different cycles of economic interests that motivated it.
Keywords: Rio de Janeiro; Human-Nature Interactions; Coastal systems; Anthropogenic impacts.

Localiza-se a 60 km da cidade do Rio de Janeiro, no mais importante entorno geoeconômico do Brasil. O objetivo desse trabalho foi avaliar a distribuição espacial da contaminação dos metais Cu, Pb, V, Cr, Cd, Co e Ni, nos sedimentos da baía. O mapa das concentrações permitiu caracterizar anomalias ao entorno da foz do rio Guandu, rio Saco do Engenho, na área da Coroa Grande, do Porto de Itaguaí, da ilha do Martins, e anomalias ao longo de faixa com direção NW-SE. Esses resultados apontam para duas fontes principais de metais: o rio Guandu e atividades portuárias. As comparações com trabalhos anteriores indicaram uma diminuição das concentrações desses metais no decorrer do tempo com transporte dos sedimentos por correntes de maré.

Evidence of sea level change at Guaratiba Mangrove, Sepetiba Bay, Brazil. (Proceedings of the 9th International Coastal Symposium), 1097 - 1100. Gold Coast, Australia, ISSN 0749.0208 Any change in sea level would lead to a migration from mangrove areas. In order to identify this migration, seven cores have been taken along a profile (SW-NE) in Guaratiba mangrove (Rio de Janeiro - Brazil) for sedimentological, biological and geochemical characterisation of the sedimentary sequence. Studies have shown the development of typical bottom bay sedimentation that corresponds to a transgressive event, consisting of muddy sediments and aged 6130 years B.P. at depth of 5.20 metres. According to bibliographical sources, this event reached its highest about 5100 years B.P., with the sea level reaching about 4.8 metres above present level. The area that corresponds to the regressive event is comprised predominantly of sand and silt. Bibli...
