    Marine Spatial Planning advancing the Ecosystem-Based Approach to coastal zone management: A review

    © 2016 Elsevier LtdPlanning a sustainable future for coastal populations requires the effective implementation of ecosystem management frameworks that explicitly incorporate human activities. A coupled framework of the Ecosystem-Based Approach with Marine Spatial Planning has been discussed and promoted by coastal managers for more than a decade. The proposed framework supports a balanced approach between development needs and the natural environment. This paper presents a qualitative review of Marine Spatial Planning case studies to gain insights into methodological approaches that account for human systems as components of the coastal environment. A total of twelve Marine Spatial Planning case studies were evaluated. Their use and integration of the Ecosystem-Based framework was assessed through a linguistic scale linked to a score of fuzzy numbers. Two management issues of interest were highlighted: how social, economic and environmental values were integrated into the spatial planning analysis; and how cross-realm connectivity was addressed by planning teams. Although the majority of case studies claimed to use the Ecosystem-Based Approach as the guiding framework, mixed results were observed. Relevant features of the Ecosystem-Based Approach were rarely included; such as the standardization of pressures from human activities, the integration of frameworks to assess ecosystem services and the implementation of Precautionary and Adaptive Management approaches. Important knowledge gaps were observed with regards to the assessment of social values, including the lack of spatial representation of ‘social connections’ to the marine environment and the lack of economic estimates of non-market values. Terrestrial and catchment units were not included in the majority of case studies; however, water quality management was used as a key element for the consideration of transboundary impacts. This comparative study reveals major differences in how coastal managers understand and integrate Ecosystem-Based Approaches with Marine Spatial Planning

    Exploring the social dimension of sandy beaches through predictive modelling

    Sandy beaches are unique ecosystems increasingly exposed to human-induced pressures. Consistent with emerging frameworks promoting this holistic approach towards beach management, is the need to improve the integration of social data into management practices. This paper aims to increase understanding of links between demographics and community values and preferred beach activities, as key components of the social dimension of the beach environment. A mixed method approach was adopted to elucidate users' opinions on beach preferences and community values through a survey carried out in Manly Local Government Area in Sydney Harbour, Australia. A proposed conceptual model was used to frame demographic models (using age, education, employment, household income and residence status) as predictors of these two community responses. All possible regression-model combinations were compared using Akaike's information criterion. Best models were then used to calculate quantitative likelihoods of the responses, presented as heat maps. Findings concur with international research indicating the relevance of social and restful activities as important social links between the community and the beach environment. Participant's age was a significant variable in the four predictive models. The use of predictive models informed by demographics could potentially increase our understanding of interactions between the social and ecological systems of the beach environment, as a prelude to integrated beach management approaches. The research represents a practical demonstration of how demographic predictive models could support proactive approaches to beach management

    Light and shade in marine conservation across European and contiguous seas

    As a response to increasing human pressures on marine ecosystems, the legislation aimed at improving the conservation and management of marine coastal areas in European and Contiguous Seas (ECS) underwent crucial advances. ECS, however, still remain largely affected by increasing threats leading to biodiversity loss. Here, by using emblematic case studies and expert knowledge, we review current conservation tools, comparing their application in different areas to assess their effectiveness, potential for synergies, and contradictions. Despite regional differences in their application, the existing legislative frameworks have the potential to regulate human activities and to protect marine biodiversity. However, four challenges remain to be addressed to fully achieve environmental policy goals: (1) Lack of shared vision representing a limitation in transboundary collaboration. Although all EU countries are committed to fulfil EU Directives and other binding international legislative acts, a remarkable heterogeneity exists among countries in the compliance with the common legislation on conservation and in their degree of implementation. (2) Lack of systematic procedures for the selection of protected marine sites. Regional and national approaches in designating Natura 2000 sites and nationally designated marine protected areas (MPAs) reflect varying conservation targets and importance of conservation issues in political agendas. (3) Lack of coherent ecological networks. Natura 2000 sites and other MPAs are still far from reaching the status of effective networks in all considered case studies. (4) Hotspot of conflicts with private economic interests prevailing over conservation aims. Recommendations are given to overcome the fragmented approach still characterizing the conservation and management of coastal marine environments. Holistic, integrated, ecosystem-based, cross-cutting approaches can avoid conflicts among institutions so as to provide effective and timely solutions to current and future challenges concerning the conservation and management of marine ecosystems and associated goods and services
