A systems approach for sustainable development in coastal zones
Newton, AliceThis Special Feature of Ecology and Society brings together important outcomes of the EU-funded project: Science-Policy Integration for Coastal System Assessment, SPICOSA. The title of the project revealed its innovative nature from the start. The premise was to bind scientific information to policy decisions and to consider the coastal zone as an integrated ecological-social-economic system. As a result, the S...
Recreation carrying capacity estimations to support beach management at Praia d...
Zacarias, D. A.; Williams, Allan T.; Newton, AliceThe purpose of this research paper is to outline the theory and practice of tourism carrying capacity assessment and its relevance as a management tool for coastal management. Based on the Tourism Carrying Capacity Assessment for Protected Areas Framework and the Image Capture Technique associated with the PAOT (people at one time) approach, this paper explores Praia de Faro as the study area and attempts to as...
Sediment and water nutrients and microalgae in a coastal shallow lagoon, Ria Fo...
Brito, Ana; Newton, Alice; Tett, Paul; Fernandes, TeresaCoastal shallow lagoons are considered to be highly important systems, which have specific biogeochemical cycles and characteristics. The assessment of sediment–water interfaces is essential to understand nutrient dynamics and to evaluate the vulnerability to eutrophication, especially in regions of restricted water exchange (RRE), such as the Ria Formosa, which have natural conditions for the accumulation of n...
Development of an optimal methodology for the extraction of microphytobenthic c...
Brito, Ana; Newton, Alice; Tett, Paul; Fernandes, TeresaBenthic microalgae are important primary producers in intertidal shallow systems. Their biomass can be estimated by the assessment of chlorophyll a concentration. A rapid and reliable method of measuring chlorophyll a is by spectrophotometer. There is however, no standard protocol for the analysis of benthic chlorophyll a. Although the most common solvent generally used is 90% acetone, some authors showed bette...
Eutrophication and some European waters of restricted exchange
Teet, Paul; Gilpin, Linda; Erlandsson, Carina; Larsson, Ulf; Kratzer, Susanne; Fouillandf, Eric; Janzen, Carol; Lee, Jae-Young; Grenzh, ChristianRegions of Restricted Exchange (RREs) are an important feature of the European coastline. They are historically preferred sites for human settlement and aquaculture and their ecosystems, and consequent human use, may be at risk from eutrophication. The OAERRE project (EVK3-CT1999-0002 concerns ‘Oceanographic Applications to Eutrophication in Regions of Restricted Exchange’. It began in July 2000, and studies si...
Impact of coastal engineering on the water quality of the Ria Formosa Lagoon, P...
Newton, Alice; Icely, JohnThe Ria Formosa is a coastal lagoon in southern Portugal. It is a Ramsar and Natura 2000 site and supports important resources such as fisheries, aquaculture and tourism. Human impacts on the Ria Formosa include urbanization, intensive agriculture, aquaculture, and coastal engineering. In this rare, long-term study of a coastal lagoon, the effects of changes in coastal zone management are documented. Data from ...
