The purpose of this paper is to highlight how data from marine protected area (MPA) surveys can be used to facilitate the development of systematic approaches to monitoring biodiversity within local government development plans and across marine bioregions.

The study focussed on coastal Barangays of the Municipality of San Luis, Aurora Philippines. A Participatory Coastal Resource Assessment (PCRA) was conducted to gather information on corals and reef fishery resources. Resultant Simpson’s biodiversity indices were calculated and compared to other MPA sites. Linkages to enhanced marine curriculum in a San Luis high school were evaluated by utilizing cultural consensus theory (CCT) on previously reported local student perception surveys as a further effort on defining pathways for localized transformation.

San Luis MPA biodiversity indices ranged from 0.56-0.8 on a scale of 0-1. This initial analysis demonstrates how local monitoring can be connected to resource assessment through biodiversity considerations and in developing local plans for site improvement linked to local economies. Results are used to demonstrate the potential for further development of an integrated approach to biodiversity monitoring across and between bioregions as a step forward in strengthening science for MPAs and biodiversity conservation for the Philippines.

The study could be used to pilot study strengthening of coastal resource management (CRM) at Municipal and Barangay levels and as well through application of CCT to the topics. The results will be used to reinforce the formulation of San Luis local development plans to better consider marine resource assessment.

This paper provides a new perspective on the use of quantitative measures of biodiversity to assist with local development plans. Projecting integrated biodiversity monitoring across and between bioregions is considered as a potential tool for facilitating climate change mitigation.

Sustainable Development Goal 14 of the United Nations aims to ‘conserve and sustainably use the oceans, seas and marine resources for sustainable development’. To achieve this goal, we must rebuild the marine life-support systems that provide society with the many advantages of a healthy ocean. Therefore, countries worldwide have been using Marine Protected Areas (MPAs) to restore, create, or protect habitats and ecosystems. Palau was one of the first countries to use MPAs as a tool to develop biodiversity within its exclusive economic zone. On 22 October 2015, Palau placed approximately 80% of its maritime territory in a network of locally monitored MPAs, which has now shown a population increase in stationary and migratory fish species. This movement towards a MPA was intentional and because of increased pressure from tourism and the increasing incursion of foreign fishing vessels in Palauan territorial waters. Since countries worldwide are using and looking towards MPAs, secondary protection projects are becoming more and more popular. This chapter highlights the practical implementations and results in Palau, how to theoretically apply this within the Greater North Sea in combination with Windmill Farms, and how the Marine Strategy Framework Directive stimulates these practices.

This study aims to explore the risk level of pufferfish and lionfish by comparing them among Turkish marines. In addition, this study focuses on comparing pufferfish with lionfish to determine which one is more dangerous for marine economics in Türkiye.

This study employs descriptive content analysis to give some qualitative evidence for the related literature. As a sample case, Türkiye was selected in the context of being a country in the Mediterranean Basin. By reviewing recent news, reports and publications, this study firstly will conclude how invasive alien marine species affect Turkish marines. Then, pufferfish and lionfish will be compared together to determine the risk level of these species for Turkish marine economics.

As a result of descriptive findings, it is seen that captured fishery has been declined in Turkey recently due to many factors including climate change, global warming, overfishing, environmental pollution and attack of invasive alien species. Pufferfish and lionfish are seen as the most spread marine species in Turkish marines. When comparing pufferfish with lionfish, it is seen that pufferfish is more dangerous than lionfish for Turkish marine economics.

This study provides descriptive and original findings as a result of comparison of pufferfish and lionfish due to their impact on Turkish marine economy. It is thought to give useful importation for the fight against invasive alien marine species in the Mediterranean Basin. Future studies can investigate different invasive alien marine species and their impacts on marine economics in the Mediterranean Basin.

Based on the Turkish cases, it is determined that there should be different policies for fight against invasive alien marine species in the Mediterranean Sea. Each marine species has different impacts on seafood market. Some of marine species can be consumed as a seafood product but some of them can't be consumed that policy makers should develop other strategies such as catching them to reduce their population in the local marines.

The spread of invasive alien marine species is still continuing in the Mediterranean Basin. Each country has been affected by the attack of invasive alien marine species. To keep sustainable seafood market and marine economics, countries should both implement common policies and develop policies specific to threats in their own countries.

This study reveals key points in the rise of invasive alien marine species in Turkish marines at first. The main contribution of this study is to be a recent sample for a country which is under attack by invasive alien marine species by giving a comparison of pufferfish and lionfish.

The purpose of this paper is to explore the biodiversity and threatened species reporting of the top 150 Fortune Global companies. The paper has two main objectives: to explore the extent to which the top 150 Fortune Global companies disclose information about their biodiversity and species conservation practices, and to explore the effects of biodiversity partners and industry on companies’ biodiversity and threatened species reporting.

The study’s sample is the top 150 Fortune Global companies. Each company’s fiscal year ending 2014 annual report, its 2014 sustainability report, and its company website were content analyzed for evidence of biodiversity and threatened species reporting. This content analysis is supplemented by a detailed analysis that focusses on the sample’s top five reporters, including a phone interview with a senior sustainability manager working at one of these companies. Finally, a regression analysis was conducted to examine the associations between companies’ biodiversity and threatened species reporting and the presence/absence of biodiversity partners and a company’s industry F&C Asset Management industry category.

The reporting on biodiversity and threatened species by the top 150 Fortune Global companies is quite limited. Few companies (less than 15) are providing any substantial reporting. It was further observed that even among the high scoring companies there is a lack of consistent reporting across all index items. A subsequent empirical examination of these companies’ disclosures on biodiversity and threatened species showed a statistically positive association between the amount of reporting and companies’ holding of biodiversity partnerships. It was also observed that firms categorized as red- and green-zone companies made more disclosures on biodiversity and threatened species than amber-zone companies.

This is the first study to systematically analyze corporate disclosures related to threatened species and habitats. While some prior studies have included the concept of biodiversity when analyzing organizations’ environmental disclosures, they have done so by examining it as one general category out of many further categories for investigating organizations’ environmental reporting. In the present study, the focus is on the specific contents of biodiversity disclosures. As such, this study has the twin research objectives of seeking to illuminate the current state of biodiversity and threatened species reporting by the world’s largest multinationals and provide an appreciation for how certain organizational and industry variables serve to influence these reporting practices. These multiple insights offer companies, and potentially regulators, understanding about how to include (or extend) disclosures on biodiversity loss and species under threat of extinction.

This study aimed to identify the potential for economic activities related to the ocean economy in Brazil to become blue economy (BE) activities, in which the concept of the Sustainable Development Goals (SDGs) is central.

To achieve the aim, the authors collected information on the SDGs and estimated data from the ocean economy sectors for the 256 Brazilian coastal cities. The authors predicted the indices for potential development of territories and sectors in the BE using two parameters: employed persons (EP) and sectoral added value (AV).

The results show that the capitals of coastal states present the highest potential indices for the BE, especially Rio de Janeiro, which accounted for 83.3% of sectoral added value in the Brazilian ocean economy with potential for sustainable development and generated 107,800 active formal jobs (26.9% of the country's total). In addition, restaurants, hotels and similar establishments are, on the Brazilian coast, the most frequent on the coastal zone and have the highest potential for BE activities.

Regarding its contributions, this research innovates by developing an indicator that can help stakeholders understand the similarities and differences between cities and regions, whether through a social, economic, or environmental lens. Therefore, by following this methodological path for measuring the BE, viewing the distinct patterns of sustainable development by area is possible, thereby supporting action plans for the fulfillment of the 2030 Agenda and the implementation of a marine spatial planning process for the country in the context of the Ocean Decade (2021–2030).

This chapter examines the Netherlands’ challenges in safeguarding its low-lying coastline against rising sea levels and the consequences of coastal defense strategies on marine life, particularly in relation to SDG14. Sea-level rise necessitates increased soft coastal defense strategies, affecting seafloor areas and marine biodiversity through sand extraction and sand nourishments. The use of hard structures for coastal defense contributes to the loss of natural coastal habitats, raising biodiversity concerns. The chapter explores the potential benefits of artificial hard surfaces as marine habitats, emphasising the need for careful design to prevent ecological problems caused by invasive species. Strategies for enhancing biodiversity on human-made hard substrate structures, including material variations, hole drilling, and adaptations, are discussed. The ecological impact of marine sand extraction is examined, detailing its effects on benthic fauna, sediment characteristics, primary production, and fish and shrimp populations. Solutions proposed include improved design for mining areas, ecosystem-based rules for extraction sites, and ecologically enriched extraction areas. The ecosystem effects of marine sand nourishments are also analysed, considering the impact on habitat suitability for various species. The chemical effects of anaerobic sediment and recovery challenges are addressed. Mitigation measures, such as strategic nourishment location and timing, adherence to local morphology, and technical solutions, are suggested. The chapter underscores the importance of education in Nature-based Solutions and announces the launch of a new BSc programme in Marine Sciences at Wageningen University & Research, integrating social and ecological knowledge to address challenges in seas, oceans, and coastal regions and support SDG14 goals.

The purpose of this paper is to review cases of artificial reefs built through additive manufacturing (AM) technologies and analyse their ecological goals, fabrication process, materials, structural design features and implementation location to determine predominant parameters, environmental impacts, advantages, and limitations.

The review analysed 16 cases of artificial reefs from both temperate and tropical regions. These were categorised based on the AM process used, the mortar material used (crucial for biological applications), the structural design features and the location of implementation. These parameters are assessed to determine how effectively the designs meet the stipulated ecological goals, how AM technologies demonstrate their potential in comparison to conventional methods and the preference locations of these implementations.

The overview revealed that the dominant artificial reef implementation occurs in the Mediterranean and Atlantic Seas, both accounting for 24%. The remaining cases were in the Australian Sea (20%), the South Asia Sea (12%), the Persian Gulf and the Pacific Ocean, both with 8%, and the Indian Sea with 4% of all the cases studied. It was concluded that fused filament fabrication, binder jetting and material extrusion represent the main AM processes used to build artificial reefs. Cementitious materials, ceramics, polymers and geopolymer formulations were used, incorporating aggregates from mineral residues, biological wastes and pozzolan materials, to reduce environmental impacts, promote the circular economy and be more beneficial for marine ecosystems. The evaluation ranking assessed how well their design and materials align with their ecological goals, demonstrating that five cases were ranked with high effectiveness, ten projects with moderate effectiveness and one case with low effectiveness.

AM represents an innovative method for marine restoration and management. It offers a rapid prototyping technique for design validation and enables the creation of highly complex shapes for habitat diversification while incorporating a diverse range of materials to benefit environmental and marine species’ habitats.
