- Fisher's perceptions about a marine protected area over timePublication . Pita, Cristina Brice; Costa, Barbara Horta e; Franco, Gustavo; Coelho, Rui; Sousa, Inês; Gonçalves, Emanuel João; Gonçalves, Jorge M. S.; Erzini, KarimThe perceptions of fishers towards the Arrábida Marine Park, a marine protected area (MPA) in the west coast of Portugal, were studied through face-to-face interviews in two different moments of the MPA life cycle. Fishers' perceptions about the MPA and the impact it had on the fishing activity over time were identified just before the full implementation of the zoning and regulations of the management plan and 10 years later. This study aimed to investigate fishers' knowledge, acceptance and perceptions about the MPA changed with time, if support for the MPA was linked to the impact of the MPA on the fishing activity, and if fishers' perceptions about the impact of the MPA on the fishing activity match with local landings trends. Results show that although knowledge about the marine park significantly improved over time, fishers' acceptance did not. A decrease on fishers' support was not substantial but occurred. Issues such as the disagreement with regulations reinforced concerns raised during the implementation of the marine park, particularly in relation to the top-down decision-making, which commonly confers minor participation, recognition and legitimacy to fishers. Apparently, fisheries benefits were still not perceived by local fishers, though they are central for fishers' support. Further, the perceived negative impacts of the park seemed to be more related to social aspects and individual interests than to impacts on catches. Addressing adequate management, enforcement and participation of local fishers is still possible and are advocated here as to contribute to the expected socioecological outcomes and respective support, leading to the future successful performance of the Arrábida Marine Park. Assessing fishers’ perceptions towards an MPA over time is central and should be included on periodical socioecological monitoring and inform an effective adaptive management
- A regulation-based classification system for marine protected areas (MPAs)Publication . Costa, Bárbara Horta e; Claudet, Joachim; Franco, Gustavo; Erzini, Karim; Caro, Anthony; Gonçalves, Emanuel JoãoMarine protected areas (MPAs) are a global conservation and management tool to enhance the resilience of linked social-ecological systems with the aim of conserving biodiversity and providing ecosystem services for sustainable use. However, MPAs implemented worldwide include a large variety of zoning and management schemes from single to multiple-zoning and from no-take to multiple-use areas. The current IUCN categorisation of MPAs is based on management objectives which many times have a significant mismatch to regulations causing a strong uncertainty when evaluating global MPAs effectiveness. A novel global classification system for MPAs based on regulations of uses as an alternative or complementing, the current IUCN system of categories is presented. Scores for uses weighted by their potential impact on biodiversity were built. Each zone within a MPA was scored and an MPA index integrates the zone scores. This system classifies MPAs as well as each MPA zone individually, is globally applicable and unambiguously discriminates the impacts of uses.
- A regulation-based classification system for marine protected areas: A response to Dudley et al. [9]Publication . Costa, Bárbara Horta e; Claudet, Joachim; Franco, Gustavo; Erzini, Karim; Caro, Anthony; Gonçalves, Emanuel JoãoDudley et al. [9] commented on our paper [11], arguing that the current IUCN objective-based categorization of protected areas, which is also used in marine protected areas (MPAs), should not be abandoned and replaced by the new regulation-based classification system [11]. Here we clarify that we do not advocate replacing the current IUCN categories, but highlight the benefits of using both the objective-based IUCN categories and the new regulation-based classification when applied to MPAs. With an increasing number of MPA types being implemented, most of them multiple-use areas zoned for various purposes, assessing ecological and socioeconomic benefits is key for advancing conservation targets and policy objectives. Although the IUCN categories can be used both in terrestrial and marine systems, they were not designed to follow a gradient of impacts and there is often a mismatch between stated objectives and implemented regulations. The new regulation-based classification system addresses these problems by linking impacts of activities in marine systems with MPA and zone classes in a simple and globally applicable way. Applying both the IUCN categories and the regulationbased classes will increase transparency when assessing marine conservation goals.
- Setting performance indicators for coastal marine protected areas: An expert-based methodologyPublication . Cardoso-Andrade, Mariana; Queiroga, Henrique; Rangel, M; Sousa, Inês; Belackova, Adela; Bentes, Luis; Oliveira, Frederico; Monteiro, Pedro; Sales Henriques, Nuno; Afonso, Carlos M. L.; Silva, Ana F.; Quintella, Cristina; Costa, José L.; Pais, Miguel P.; Henriques, Sofia; Batista, Marisa I.; Franco, Gustavo; Gonçalves, Emanuel J.; Henriques, Miguel; Leonardo, Teresa; Coelho, Paula; Comas-González, Robert; Fernández, Laura P.; Quiles-Pons, Carla; Costa, André; Espírito-Santo, Cristina; Castro, João J.; ARENAS, FRANCISCO; Ramos, Sandra; Ferreira, Vasco; Gonçalves, Jorge M. S.; Horta e Costa, BarbaraMarine Protected Areas (MPAs) require effective indicators to assess their performance, in compliance with the goals of relevant national and international commitments. Achieving and prioritizing shortlists of multidisciplinary indicators demands a significant effort from specialists to depict the multiple conservation and socioeconomic interests, and the large complexity of natural systems. The present paper describes a structured expert-based methodology (process and outputs) to co-define a list of multidisciplinary MPA performance indicators. This work was promoted by the management authority of coastal MPAs in mainland Portugal to gather a consensual and feasible list of indicators that would guide the design of a future national monitoring program. Hence, Portuguese coastal MPAs served as a case study to develop such a process between 2019 and 2020. In the end, participants (1) agreed on a shortlist of prioritized indicators (i.e., environmental, governance, and socioeconomic indicators) and (2) defined minimum monitoring frequencies for the indicators in this list, compatible with the potential replicability of the associated survey methods. The present approach recommends that management plans incorporate monitoring procedures and survey methods, with a validated list of indicators and associated monitoring periodicity, agreed among researchers, MPA managers and governance experts. The proposed methodology, and the lessons learned from it, can support future processes aiming to define and prioritize MPA performance indicators
