Sustainable coastal zones? Amatter of "sense and sensibility" Comparative analysis between Aveiro Lagoon (Portugal) and Sepetiba Bay (Brazil)

Purpose - The purpose of this paper is to perform a comparative analysis between Aveiro's Lagoon (Portugal) and Sepetiba Bay (Brazil), in order to understand the similarities and differences between these two coastal zones, in terms of human occupation. 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.
