Este artigo apresenta os diferentes aspectos da proteção do ambiente litorâneo abordando três pontos essenciais. O primeiro evoca a instalação de áreas marinhas protegidas (AMP) em um contexto socioeconômico e político, destacando seu funcionamento e a noção de “ efeito reserva”. O segundo mostra a importância das AMP na proteção da biodiversidade marinha. Finalmente, o terceiro ponto exemplifica a avaliação do meio natural e aborda, de maneira geral, o valor econômico das espécies e da “Natureza” na ocorrência de degradação. Contributions of the marine protected areas for the conservation and management of the marine environment Abstract This article presents the various aspects of the littoral environmental protection by approaching three important points. The first evokes the installation of the marine surfaces protected in a socio-economic and political context. The operation of the reserves and the concept of “ reserve effect “ are explained. The second explains the interest of MPA to protect the marine biodiversity. Lastly, the third point shows the evaluation of the natural environment and more generally of the economic value of the species and “Nature” in the event of degradation.

AbstractConservation of the high seas marine environment poses a significant challenge to policy-makers and managers. Marine conservation efforts are often hindered by the lack of data and the difficulties in addressing multiple, and typically conflicting uses. The majority of extant Marine Protected Areas (MPAs) are in coastal or tropical regions within national jurisdiction. Conservation of high seas MPAs has emerged on the international agenda as a critical issue requiring the application of novel approaches, international cooperation and political will. Knowledge and understanding of the marine environment and data on marine biodiversity are all typically limited for the high seas, and the use of surrogates to assist in the identification of areas of high conservation value is one possible mechanism to address and potentially overcome these limitations. Drawing upon a database spanning more than 20 years and containing approximately 140 000 records of seabird sightings at sea, this study assesses the potential use of seabirds as surrogates for marine biodiversity in the Indian sector of the Southern Ocean. At-sea ranges, species diversity and the distributions of endangered species may be appropriate selectors or filters to identify areas with high conservation values. Integrating policy with science provides an appropriate mechanism to identify and prioritise MPAs in the Southern Ocean.

Mexican Caribbean

In the Mexican Caribbean, 15 marine protected areas (MPAs) have been established for managing and protecting marine ecosystems. These MPAs receive high anthropogenic pressure from coastal development, tourism, and fishing, all in synergy with climate change. To contribute to the MPAs’ effectiveness, it is necessary to provide a long-term observation system of the condition of marine ecosystems and species. Our study proposes the establishment of a new marine biodiversity monitoring program (MBMP) focusing on three MPAs of the Mexican Caribbean. Five conservation objects (COs) were defined (coral reefs, seagrass beds, mangroves, marine turtles, and sharks-rays) for their ecological relevance and the pressures they are facing. Coral reef, seagrass and mangroves have multiple biological, biogeochemical and physical interactions. Marine turtles are listed as endangered species, and the status of their populations is unknown in the marine area of the MPAs. Elasmobranchs play a key role as top and medium predators, and their populations have been poorly studied. Indicators were proposed for monitoring each CO. As a technological innovation, all information obtained from the MBMP will be uploaded to the Coastal Marine Information and Analysis System (SIMAR), a public, user-friendly and interactive web platform that allows for automatic data management and processing.

Abstract In recent years, the international community has become increasingly aware of the growing threats to marine biodiversity in areas beyond national jurisdiction (abnj), and international discussions on a new international legally binding are underway. In parallel, some States, through regional organisations, have progressively extended their activities into abnj, particularly through the development of area-based management tools (abmts). In this article, we consider how actors in the Western Indian Ocean (wio) might engage in abnj governance. In particular, we develop some possible scenarios for developing abmts in the wio, including through the development of fisheries closures, the establishment of marine protected areas (mpas), and the adoption of abmts under the auspices of relevant international organisations. We conclude that while the wio is currently not the most advanced region in terms of ongoing efforts to improve the governance of abnj, there are already some positive signals and promising options for the future.

Anthropogenic Threats

The world’s oceans face unprecedented anthropogenic threats in the globalized era that originate from all over the world, including climate change, global trade and transportation, and pollution. Marine protected areas (MPAs) serve important roles in conservation of marine biodiversity and ecosystem resilience, but their success is increasingly challenged in the face of such large-scale threats. Here, we illustrate the utility of adopting the interdisciplinary telecoupling framework to better understand effects that originate from distant places and cross MPA boundaries (e.g., polluted water circulation, anthropogenic noise transport, human and animal migration). We review evidence of distal processes affecting MPAs and the cutting-edge approaches currently used to investigate these processes. We then introduce the umbrella framework of telecoupling and explain how it can help address knowledge gaps that exist due to limitations of past approaches that are centered within individual disciplines. We then synthesize five examples from the recent telecoupling literature to explore how the telecoupling framework can be used for MPA research. These examples include the spatial subsidies approach, adapted social network analysis, telecoupled qualitative analysis, telecoupled supply chain analysis, and decision support tools for telecoupling. Our work highlights the potential for the telecoupling framework to better understand and address the mounting and interconnected socioeconomic and environmental sustainability challenges faced by the growing number of MPAs around the world.

Abstract The marine environment represents a central component of Maltaís local environment, and its ecosystem services play a vital role in supporting the economy as well as human well-being. Plans have been made to protect the unique ecology found within Maltese waters through the institution of five marine protected areas (MPAs). This quantitative study assessed the environmental knowledge and attitudes of the Maltese public towards the local marine environment, MPAs and education for sustainable development (ESD). A questionnaire was administered to members of the public (n = 200) at three different locations. The study found that although the Maltese public strongly appreciates the beauty of Maltaís marine environment, the level of knowledge surrounding the marine environment is low. Furthermore, the research indicates that while the public agrees that the marine environment should be protected, there is a notable lack of awareness of the five local MPAs. Based on the research findings, a model linking ESD to MPAs and aiming to foster a sense of ownership among the public by encouraging their involvement in the management of local MPAs is proposed.

Protection Cost

Fisheries managers in the United States are required to identify and mitigate the adverse impacts of fishing activity on essential fish habitat (EFH). There are additional concerns that the viability of sessile noncommercial species, animals that are habitat dependent and (or) are themselves constituents of fishery habitat, may be threatened by fishing activities. We propose a system of individual habitat quotas (IHQ) to achieve habitat conservation and species protection cost effectively. Individual quotas of habitat impact units would be distributed to fishers with an aggregate quota set to maintain a target habitat "stock". Using a dynamic, spatially explicit fishery simulation model, we explore the efficiency and effectiveness of an IHQ policy versus marine protected areas (MPAs) for conserving habitat-dependent, sessile species of unknown spatial distributions. Our findings indicate that an IHQ policy with a conservatively established habitat target is better suited to the protection of sessile nontarget species than a rotating or fixed MPA policy.

Marine Protected Areas (MPAs) are one of the main tools for protecting marine biodiversity, but they are often selected on the basis of little or no ecological data. As a result, there is a risk that MPAs will not successfully protect marine biodiversity. We propose an operational framework to help prioritize the need for information, and to direct the subsequent collection of appropriate biological data. The framework consists of 7 steps: (1) formulating clearly-defined objectives, (2) a broad-scale classification based on easily accessible surrogates, (3) identifying biological variables for detailed survey, (4) assessing the utility of surrogates, (5) designing and implementing the biological survey, (6) modelling and using inferential statistics to optimize the use of existing knowledge, and (7) validating candidate areas. Each step in the framework involves identifying areas of uncertainty, and the risks that a MPA will fail to achieve its intended objectives. The aim of our operational framework is to make the risks and uncertainties clear, and to force decisions to be made to minimise their potential impact on the outcome of the MPA selection process. We identify four key ecological uncertainties in MPA identification: (1) the reliability of surrogates, (2) spatial uncertainty in survey data, (3) temporal uncertainty in the patterns of the biodiversity in the MPA, and (4) uncertainty in the degree to which important ecological processes will be maintained. We conclude that the key to success in a MPA selection process is the use of clearly specified objectives for the MPA and an explicit assessment of uncertainties involved. We contend that without a competent ecological basis, new MPAs may be little more than the political exercises to appease lobby groups, and are unlikely to be effective tools in protecting marine biodiversity from continuing decay.

Abstract Luna, B., Valle Pérez, C., and Sánchez-Lizaso, J. L. 2009. Benthic impacts of recreational divers in a Mediterranean Marine Protected Area. – ICES Journal of Marine Science, 66: 517–523. The features of many Marine Protected Areas (MPAs) have increased scuba diving tourism in these areas. Impacts caused by recreational scuba activity vary widely among different divers with differing underwater behaviour. We studied diver underwater behaviour, the effects on the natural environment, and the characteristics that may influence diver behaviour. In all, 181 recreational divers were followed, and contacts and the effects produced were recorded. Information on diver profile and dive features was recorded. Field sampling revealed that 175 of the divers observed (96.7%) made at least one contact with the seabed, with a mean contact of 41.20 ± 3.55 (mean ± s.e.) per diver per 10 min. Flapping was the most frequent type of contact, and the main damage by this action was to raise sediment. Contact with the seabed was greater for males than for females, inexperienced divers than for experienced divers, camera or lantern (dive light) users than for non-users, and divers unaccompanied by a dive leader or who had not been briefed about avoiding seabed contact before undertaking a dive than for accompanied or briefed divers. A greater understanding of the causes of harmful behaviour may be useful for stricter management, reducing diving damage and assuring the sustainability of this activity in MPAs.

Societal Preferences

Marine protected areas (MPAs) are increasingly being used as conservation tools in the marine environment. Success of MPAs depends upon sound scientific design and societal support. Studies that have assessed societal preferences for temperate MPAs have generally done it without considering the existence of discrete groups of opinion within society and have largely considered offshore and deep-sea areas. This study quantifies societal preferences and economic support for coastal MPAs in Wales (UK) and assesses the presence of distinct groups of preference for MPA management, through a latent class choice experiment approach. Results show a general support for the protection of the marine environment in the form of MPAs and that society is willing to bear the costs derived from conservation. Despite a general opposition toward MPAs where human activities are completely excluded, there is some indication that three classes of preferences within society can be established regarding the management of potentially sea-floor damaging activities. This type of approach allows for the distinction between those respondents with positive preferences for particular types of management from those who experience disutility. We conclude that insights from these types of analyses can be used by policy-makers to identify those MPA designs and management combinations most likely to be supported by particular sectors of society.

Different Levels

In the last decades, several targets for marine conservation were set to counter the effects of increasing fishing pressure, e.g., protecting 10% of the sea by 2020, and establishing large-scale marine protected areas (LSMPAs). Using the ‘reconstructed’ catch data for 1950 to 2018 made available by the Sea Around Us initiative, we show that the declaration of an exclusive economic zone (EEZ) in 1983 by the U.S.A. and its protection by the U.S. Coast Guard had a much bigger impact on catches around the Northwestern Hawaiian Islands than the subsequent creation of a LSMPA. This is similar to Pitcairn Islands, a UK territory. Trends differed sharply in the Galapagos and New Caledonia, where neither their EEZ declaration nor the LSMPA (by Ecuador in 1988 and by France in 2014) stopped local fisheries from continuous expansion. Our results also demonstrate that in the studied multizone LSMPAs continued local fishing induces a ‘fishing down’ effect wherein the mean trophic level (TL) declined, especially in the Galapagos, by 0.1 TL per decade. Stakeholders’ responses to a short questionnaire and satellite imagery lent support to these results in that they documented substantial fishing operations and ‘fishing the line’ within and around multizone LSMPAs. In the case of EEZs around less populated or unpopulated islands, banning foreign fishing may reduce catch much more than a subsequent LSMPA declaration. This confirms that EEZs are a tool for coastal countries to protect their marine biodiversity and that allowing fishing in an MPA, while politically convenient, may result in ‘paper parks’ within which fishing can cause the same deleterious effects as in wholly unprotected areas.
