“…Although present assessment methods are limited in the guidance they can provide to man agers, development of multistressor assessment methods, albeit needed, will be complex and most effective if developed at the local level. However, a major issue is determining meth ods that are accurate and acceptable on a large-scale basis that can then be applied at a smaller scale (and need to be intercalibrated; Borja et al, 2007).…”

“…For example, speciesabundance-biomass (SAB) curves (Pearson and Rosenberg, 1978), abundance-biomass comparisons (ABCs, Warwick, 1986), AMBI (Borja et al, 2000), and diversity indices. (e.g., Rosenberg et al, 2004;Borja et al, 2007). Given the estuarine quality paradox (see this concept in the next section), however, the main problem is that some of these methods detect naturally as well as anthropogenically stressed areas, thus decreasing the ability of detecting and maximizing the signal (anthropogenic change)-to-noise (natural change) ratio.…”

There is an increasing need in assessing ecological quality and integrity of estuaries and lagoons. This chapter shows the most recent efforts in assessing individual biological elements (from phytoplankton to fishes), together with the integrative tools developed in different geographical areas worldwide. However, reducing complex information from multiple ecosystem elements to a single color or value is a substantial challenge to marine scientists, and requires the integration of different disciplines (chemists, engineers, biologists, ecologists, physics, managers, etc.), to reach agreement on the final assignment of ecological status. Hence, in the near future, emphasis needs to be directed at understanding the complexities of estuarine system functioning rather than simplifying and scaling down the system into smaller components.

“…The DPSIR scheme of indicators is a flexible framework that can be adapted to the necessities of specific programmes to stress the different indicator types. It has been widely used for different purposes, for the implementation of the European Water Framework Directive [15][16][17], coastal zone studies [10,[18][19][20][21][22][23][24][25][26] and in fisheries management [14]. This methodology works well at simplifying the complexity of environmental management and makes easier communication among policy makers, scientists and the general public, improving the cooperation among them.…”

a b s t r a c tA general conceptual framework for the management of marine protected areas (MPAs) was developed. The driver-pressure-state-impacts-response (DPSIR) framework was used to determine the elements affecting MPAs. The developed evaluation framework helped to select an appropriate suite of indicators to support an ecosystem approach, an assessment of the MPAs functioning and policy decisions. Gaps derived from the management and policy responses in the MPAs were also outlined. It was concluded that the DPSIR framework can help to simplify the complexity of MPA management. This document is a tool for policy makers, scientists and general public on the relevance of indicators to monitor changes and MPAs management.

“…This enables the susceptibility of waters to respond to high nutrient inputs, identified by Painting et al (2007), and linked to light availability and water residence times, to be taken into consideration. Similar indices are being developed with respect to a range of parameters that may be affected by excessive nutrient inputs including benthos and attached macroalgae (Borja et al, 2007;Wilkinson et al, 2007).…”

ABSTRACT1. Increased inputs of nutrients to estuaries can lead to undesirable effects associated with eutrophication, including algal blooms, changes in species composition and bottom anoxia. Several estuaries and coastal areas around the UK have increased nitrogen (N) and phosphorus (P) concentrations, elevated concentrations of chlorophyll a and changes in algal community composition and abundance. This paper reviews the pressures that lead to high nutrient concentrations in estuaries and considers the likely effectiveness of current and proposed regulatory actions.2. The main sources of nutrients to estuaries are river runoff, sewage discharges, atmospheric inputs and possibly submarine groundwater discharges, although little is known about the latter. Significant reductions in N and P inputs have been realized following application of the EU's Urban Waste Water Treatment Directive. Atmospheric NO x and NH x emissions have also decreased and are expected to decrease further in the next decade as implementation of existing legislation continues, and new controls are introduced for activities such as shipping.3. Agricultural inputs reach estuaries principally through diffuse sources, either in surface water (and in some areas possibly groundwater) or, for N, via the atmosphere. Over 10 years ago the Nitrates Directive was introduced to tackle the problem of N discharges from agriculture but little change in N loads to estuaries has been recorded.4. To meet the aims of the EU Water Framework Directive, for at least 'good' ecological status, more rigorous application and implementation of the Nitrates Directive, together with changes in the Common Agriculture Policy and farming practice are likely to be needed. Even then, the slow response of the natural environment to change and the inherent variability of estuaries means that their responses may not be as predicted. Research is needed into the relationship between policy drivers and environmental responses to ensure actions taken will achieve the planned results.
