Summary
Coastal environments, such as estuaries, are the prime examples of how the presence and influence of man is already, in many ecosystems, part of the dynamics of the natural system. Historically, man has been changing the landscape, using the ecosystem services that coastal systems offer and in many cases it is no longer possible or desirable to exclude him from the landscape. In small estuaries, changes in use and / or impact intensification can have devastating effects of sound alteration of the system and even its functional disappearance. These estuaries, inserted in the context of more or less humanised watersheds, are subject to impacts of different scales and magnitudes, so for the purposes of management and analysis of their functional permanence, probably the best option is an ecosystem approach that goes beyond the size of the small estuary. The challenge will then be the choice of impact descriptors that will dictate the vulnerability of each system. In this work, an adaptation of a vulnerability analysis made to small estuaries of the Portuguese coast was used, which not only quantified it, but also opened the way for the management of these ecosystems. It was concluded that the understanding of the multiple pressures that lead to the degradation of ecosystems is essential for the definition of lines of intervention and protection. The scarce knowledge about small estuaries should not be a limitation to management, but rather a warning sign of their potential degradation and risk of functional disappearance.
