The abundance, composition and sources of marine litter were determined on beaches located in the seven countries of the Adriatic-Ionian macroregion, namely Albania, Bosnia and Herzegovina, Croatia, ...Greece, Italy, Montenegro and Slovenia. A total of 70,581 marine litter items were classified and recorded through one-year long surveys carried out in 31 sites. The average litter density of 0.67 items/m2 found within this study is considered to be relatively high. The beaches investigated differed in terms of human-induced pressures; their majority is classified either as semi-urban or semi-rural, while very few beaches could be characterized as urban or remote/natural. The majority of litter items were made of artificial/anthropogenic polymer materials accounting for 91.1% of all litter. Litter from shoreline sources accounted for 33.4% of all litter collected. The amount of litter from sea-based sources ranged in the different countries from 1.54% to 14.84%, with an average of 6.30% at regional level.
•1-year long marine litter surveys were carried out in 31 beaches in 7 countries of the Adriatic and Ionian Seas.•A standardized methodology was used for all 180 beach litter surveys.•The investigation revealed a beach litter density of 0.67 items/m2, which is relatively high.•The results provide a blueprint for the setup of beach litter monitoring and assessment programmes.•A large fraction of the top 20 items found were short-lived single-use plastic items.
Marine protected areas (MPAs) socio-ecological effectiveness depends on a number of management and governance elements, among which stakeholder engagement and community support play key roles. ...Collaborative conservation initiatives that engage stakeholders in action research and knowledge co-production processes can enhance management and governance of MPAs. To design effective strategies aimed at reconciling biodiversity conservation and management of sustainable human uses, it is key to assess how local communities respond to such initiatives and identify the set of contextual factors, institutional, local and individual, potentially affecting these responses. This paper presents the approach and results of one such initiative, spanning 6 EU countries and 11 MPAs in the Mediterranean Sea, focusing on small-scale fishers as key MPA users. Through a collaborative project, managers and fishers agreed upon specific governance interventions (e.g. increasing stakeholder engagement, engaging fishers in monitoring activities, reducing fishing efforts) to be implemented in each MPA for one year. Structured surveys queried: MPA managers on the MPA context, governance structure, feasibility and effectiveness of the tested interventions; and small-scale fishers on their perceptions of the impact of the tested interventions on a set of 9 socio-ecological variables (e.g. amount of fish caught, level of participation in decision-making, support for the MPA). Results revealed that the interventions tested were relatively feasible, effective and cost-effective. Fishers reported positive perceptions of the interventions for the 9 variables considered, especially for level of support for the MPA and for those associated with aspects of governance. Proportional odds models highlighted perceived effects are maximized under certain institutional, local and individual circumstances (e.g. old MPAs, small fisher communities, and fishers with a high proportion of income from fisheries). Findings highlight that employing good governance processes involving stakeholders may rapidly generate improved local support for conservation and provide insights for potential leverage points upon which to act to maximize perceived effectiveness and enhance support toward MPAs.

Marine litter is a threat to marine life and an economic burden for coastal communities, but efforts to address the issue are hampered by the lack of data for many countries. We performed the first ...harmonized assessment of seafloor litter (trawl and visual surveys) in six countries of the Adriatic-Ionian macroregion. Seafloor litter showed an uneven distribution throughout the area, with large differences in litter densities and composition among countries and locations. An emerging problem in the area resulted in short-term & single-use objects that represented the largest fraction of litter. Packaging was the economic sector contributing most to seafloor litter on the continental shelf and upper slope, while in some areas aquaculture (mussel farming) represented a key activity producing marine litter. In coastal areas and bays (e.g. Boka Kotorska bay, Montenegro), seafloor litter was mainly related to construction activities and electronic goods, which are a consequence of fly-tipping/illegal dumping.
•First assessment of seafloor litter (3–281 m) in the Adriatic-Ionian macroregion•First data on seafloor litter in Slovenia, Croatia and Bosnia & Herzegovina•The distribution of marine debris is uneven both at country and local level.•Single-use plastic items are the large majority of litter found.•Mussels farming locally represents a major contributor to seafloor litter.
Ecotourism is a potential lever for sustainable development, but common standards and approaches lack to manage and monitor the impact of defined packages on natural resources and local communities. ...A customized version of Ecological Footprint Accounting is evaluated here to assess its usefulness as analytical tool to quantitatively analyse the environmental pressures associated with ecotourism packages developed in and around Protected Areas in the Mediterranean Region. Within the framework of the EU-funded DestiMED project, a bottom-up, participatory approach was developed for managing and monitoring 13 ecotourism packages by involving local tourism stakeholders and service providers. The application of Ecological Footprint Accounting relied on data sourced from local service providers to complement existing statistics and datasets, and was used in an empirical iterative process to provide local tourism stakeholders with recommendations to guide them in the management of a low-impact tourism offer. International travel to and from the 13 destinations was found to place a Footprint on the environment – mainly because of carbon emissions – higher than that of the entire stay at destination. Footprint results of the packages revealed some overlooked tourism's impacts on ecosystems due to unexpected drivers, such as the Food & Drink services offered to tourists at destination. Results indicate that managing tourism product development at destination, and investing in providing knowledge on the principles of sustainability, could lower ecotourism's impacts whilst contributing to building resilience and aiding the post-COVID recovery of destinations.
This article tested the applicability and usefulness of Ecological Footprint Accounting (EFA) to assess ecotourism packages developed in and around Protected Areas (PAs) across the Mediterranean Region. A customized version of Ecological Footprint Accounting is suitable for managers and can be used to quantitatively assess the multiple pressures of the activities included in ecotourism packages through a bottom up approach. This innovative monitoring process typically fosters the engagement with the local service providers, which is key for a sustainability monitoring of the touristic offer. Applied to ecotourism packages, EFA allows identifying the main ecosystems under pressure as well as the main drivers causing such pressures. This information is useful to understand the actual impacts caused by the packages offered in their territory, and – when combined with tangible recommendations for improvements – to help adjust the services offered in the packages to possibly reduce environmental impacts.
