Abstract and Figures

Decentralized management of marine resources by local governments yields an enhanced opportunity to protect, restore, and create sustainable marine biodiversity in the provision of ecosystem services. However, due to the complexities associated with designing a level of protection for a specific marine resource, local stakeholders may find the process challenging, which may have adverse effects resulting from delayed conservation initiatives. Thus, under various criteria, a systematic approach that assigns a level of protection to marine resources is critical in managing these resources. Despite this criticality, such an agenda gains limited attention from the domain literature. This work advances this gap by proposing a multiple criteria sorting (MCS) method that comprehensively assigns marine resources to a pre-defined set of protection categories under the evaluation of several criteria. It utilizes (1) the entropy method in obtaining the priority weights of the identified criteria associated with evaluating the reef status of marine sites and (2) an extension of the combined compromise solution sorting method, termed CoCoSort, in evaluating marine sites to a pre-determined set of categories (i.e., Category 1, Category 2, Category 3), arranged in increasing order of protection. With the available indicators in the literature, the proposed CoCoSort was implemented in an actual case study of eight marine sites in an eastern Philippine municipality. Findings reveal that feather stars density, giant clams density, and butterfly abundance comprise the top priority criteria in evaluating the case sites. On the other hand, five identified sites are found to be under the maximum protection category, while three sites should be given moderate protection. Both sensitivity and comparative analyses show the efficacy of the proposed CoCoSort. The insights would help local governments manage the biodiversity protection of their marine environments.

Abstract
Decentralized management of marine resources by local governments yields an enhanced opportunity to protect, restore, and
create sustainable marine biodiversity in the provision of ecosystem services. However, due to the complexities associated
with designing a level of protection for a specific marine resource, local stakeholders may find the process challenging, which
may have adverse effects resulting from delayed conservation initiatives. Thus, under various criteria, a systematic approach
that assigns a level of protection to marine resources is critical in managing these resources. Despite this criticality, such
an agenda gains limited attention from the domain literature. This work advances this gap by proposing a multiple criteria
sorting (MCS) method that comprehensively assigns marine resources to a pre-defined set of protection categories under
the evaluation of several criteria. It utilizes (1) the entropy method in obtaining the priority weights of the identified criteria
associated with evaluating the reef status of marine sites and (2) an extension of the combined compromise solution sorting
method, termed CoCoSort, in evaluating marine sites to a pre-determined set of categories (i.e., Category 1, Category 2,
Category 3), arranged in increasing order of protection. With the available indicators in the literature, the proposed CoCoSort
was implemented in an actual case study of eight marine sites in an eastern Philippine municipality. Findings reveal that
feather stars density, giant clams density, and butterfly abundance comprise the top priority criteria in evaluating the case
sites. On the other hand, five identified sites are found to be under the maximum protection category, while three sites should
be given moderate protection. Both sensitivity and comparative analyses show the efficacy of the proposed CoCoSort. The
insights would help local governments manage the biodiversity protection of their marine environments.

Tropical and subtropical coastal flats are shallow regions of the marine environment at the intersection of land and sea. These regions provide myriad ecological goods and services, including recreational fisheries focused on flats-inhabiting fishes such as bonefish, tarpon, and permit. The cascading effects of climate change have the potential to negatively impact coastal flats around the globe and to reduce their ecological and economic value. In this paper, we consider how the combined effects of climate change, including extremes in temperature and precipitation regimes, sea level rise, and changes in nutrient dynamics, are causing rapid and potentially permanent changes to the structure and function of tropical and subtropical flats ecosystems. We then apply the available science on recreationally targeted fishes to reveal how these changes can cascade through layers of biological organization—from individuals, to populations, to communities—and ultimately impact the coastal systems that depend on them. We identify critical gaps in knowledge related to the extent and severity of these effects, and how such gaps influence the effectiveness of conservation, management, policy, and grassroots stewardship efforts.

With the increasing risk to human health and environmental issues, the selection of appropriate management and treatment of healthcare waste has become a major problem, especially in developing countries. There are various alternatives to dispose of health care waste. The important is to assess the best alternative among them. The assessment of each alternative should be done based on public health, psychological, economic, environmental, technological, and operational aspect. The selection of the best health care waste treatment (HCWT) alternative is a complicated, multi-criteria decision-making (MCDM) problem involving numerous disparate qualitative and quantitative features. Hence, in this research article, the MCDM method is presented for estimating and choosing the best alternative of HCWT by COPRAS technique in a Pythagorean fuzzy set (PFS). Here, in this paper, first of all, a new entropy measure on PFSs is proposed and its validity is studied. Thereafter, the MCDM technique Complex Proportional Assessment (COPRAS) is discussed in which the criteria weights are assessed by the proposed entropy measure and score function to enhance an efficacy and efficiency of the proposed technique. Furthermore, the above-defined technique is employed to resolve the real-life problem to obtain the best treatment alternative to disposal of the health care waste. Finally, sensitivity analysis is presented to rationale the proposed viewpoint for prioritizing HCWT alternatives.

Giant clams are threatened by overexploitation for human consumption, their valuable shells and the aquarium trade. Consequently, these iconic coral reef megafauna are extinct in some former areas of their range and are included in the International Union for Conservation of Nature (IUCN) Red List of Threatened Species and Convention on International Trade in Endangered Species of Wild Fauna and Flora. Now, giant clams are also threatened by rapid environmental change from both a suite of local and regional scale stressors and global change, including climate change, global warming, marine heatwaves and ocean acidification. The interplay between local- to regional-scale and global-scale drivers is likely to cause an array of lethal and sub-lethal effects on giant clams, potentially limiting their depth distribution on coral reefs and decreasing suitable habitat area within natural ranges of species. Global change stressors, pervasive both in unprotected and protected areas, threaten to diminish conservation efforts to date. International efforts urgently need to reduce carbon dioxide emissions to avoid lethal and sub-lethal effects of global change on giant clams. Meanwhile, knowledge of giant clam physiological and ecological responses to local–regional and global stressors could play a critical role in conservation strategies of these threatened species through rapid environmental change. Further work on how biological responses translate into habitat requirements as global change progresses, selective breeding for resilience, the capacity for rapid adaptive responses of the giant clam holobiont and valuing tourism potential, including recognizing giant clams as a flagship species for coral reefs, may help improve the prospects of these charismatic megafauna over the coming decades.

Significance Plastic waste causes harm to marine life and has become a major global environmental concern. The recent COVID-19 pandemic has led to an increased demand for single-use plastic, intensifying pressure on this already out-of-control problem. This work shows that more than eight million tons of pandemic-associated plastic waste have been generated globally, with more than 25,000 tons entering the global ocean. Most of the plastic is from medical waste generated by hospitals that dwarfs the contribution from personal protection equipment and online-shopping package material. This poses a long-lasting problem for the ocean environment and is mainly accumulated on beaches and coastal sediments. We call for better medical waste management in pandemic epicenters, especially in developing countries.

Coral reefs of the Tres Marias Islets provide habitat for diverse marine organisms and significantly contribute to the economic activities in Northwest Leyte, Eastern Philippines. Unfortunately, no comprehensive and detailed study was conducted to determine the status of the hard coral and the reef-associated benthic resources in Tres Marias Islets, particularly, Tabuk Islet being a marine protected area. Baseline coral resources assessment was done in randomly identified stations in the Tres Marias Islets. The modified Reef Check methodology was used to determine the percentage covers and generic diversity based on the Taxonomic Agglomeration Units (TAUs). Tabuk Islet had the highest hard coral cover and generic diversity than the other two Islets. Four Evolutionary Distinct and Globally Endangered (EDGE) hard coral species were recorded in Tres Marias Islets. Furthermore, a coral bleaching event was observed in the area and reported officially in this study. The findings of this study highlight the effectiveness of the establishment of a marine protected area in the growth and recruitment of reef-building corals.

During pandemics and outbreaks, the prevalence of fear among tourists reduces travel interests. To gradually reopen the tourism industry, subscribing to domestic tourism is a crucial mitigation strategy. Although an important agenda, evaluating the perceived degree of exposure of tourists to COVID-19 in tourist sites functioning under the domestic tourism initiatives has not been explored in the emerging literature. Thus, this work addresses this problem domain by proposing the use of TOPSIS-Sort – a recently introduced multiple criteria sorting method. To demonstrate such an application, 20 tourist sites in a central Philippine province are evaluated under six attributes that define exposure to COVID-19. With 208 survey participants, results show that 12 sites are assigned to the ‘moderate exposure’ class, and eight under the ‘high exposure’ class, with no tourist site assigned to the ‘low exposure’ class. The proposed approach offers primary stakeholders (i.e. government, tourist operators, and tourists) a decision support tool in view of tourism recovery.

Costa Rica is one of the most biodiverse countries in the world, and stands out for its commitment to conservation. Along its two coasts, it presents a great heterogeneity of ecosystems and social realities. Social factors, more than physical-natural factors, determine the success or failure of an MPA, so they must be urgently incorporated into all phases of MPA management. The objective of this work is to analyze the management of three marine protected areas, to establish improvements. These areas are Santa Rosa National Park, Marino Ballena National Park and Cahuita National Park. The methodology used assesses 26 indicators grouped into 4 key factotres: management body, planning subprocess, public participation, and implementation subprocess. The results of this evaluation are 5 possible scenarios. These scenarios have been termed (from the ideal situation to the least favourable): proactive (1), learning (2), interactive (3), centralized (4) and formal (5) management. The results of this study show that both Santa Rosa and Cahuita present a proactive scenario (1), with high citizen participation, although in practice the way the two MPAs are managed is very different. Marino Ballena, on the other hand, is in scenario 5 (formal), and a series of measures are presented that can move it towards scenario 2 (learning). In general, MPA management in Costa Rica tends to be adaptive, with high public participation, as determined by its public policies. However, the existence of a public policy favors but does not guarantee success in MPA management, as can be seen in the difference in results. Therefore, the periodic evaluation of its management, allowing for feedback, is essential.

The extent and speed of recent changes in reef coral abundances due to ocean warming and human impacts require more widespread capability to map and measure these changes, especially in countries like the Philippines. We present “C30”, a simple, rapid, scientifically valid, and low-cost method for skin divers or freedivers to take random photo-quadrat images within predefined stations on the upper reef slope. C30 yields coral cover data similar to those collected using the more intensive C5 method and can be as powerful in detecting small differences in reef cover. Less time is also needed for training personnel and sampling. However, more photo-quadrat images, better cameras, and closer collaboration with local scientists are required if higher precision data and estimates of coral diversity are needed from C30. C30 is a valuable tool for participatory, community-based citizen science monitoring of coral reefs.

Purpose Travel interests of tourists during pandemics and outbreaks are reduced due to the prevalence of fear. It induces lifestyle changes, which may hinder efforts to recover the tourism value chain during post-COVID-19 lockdowns. Subscribing to domestic travel and domestic tourism is deemed to mitigate fear and gradually reopen the tourism industry. Although a crucial initiative, evaluating the perceived degree of exposure of tourists to COVID-19 in tourist sites operating under domestic tourism has not been fully explored in the emerging literature, which forms the main departure of this work. Design/methodology/approach The problem domain is addressed by adopting multiple criteria sorting method – the VIKORSORT. To demonstrate such application, with 221 survey participants, 35 tourist sites in a province in the central Philippines struggling to revive the tourism industry are evaluated under six attributes that characterize tourists' exposure to COVID-19. To assess its efficacy, the performance of the VIKORSORT is compared to other distance-based multiple criteria sorting methods (i.e. TOPSIS-Sort and CODAS-SORT). Findings Results show that proximity and volume of tourist arrivals are considered on top of the priority list of attributes. The use of VIKORSORT yields the assignment of 27 sites to the “moderate exposure” class, and eight under the “high exposure” class, with no tourist site assigned to the “low exposure” class. Sorting the tourist sites reveals some observations that tourists prefer sites (1) with open spaces, (2) with activities having limited group dynamics, (3) that are nature-based, and (4) with tourist arrivals that are not relatively high, with enough land area to practice social distancing. In addition, the assignments of the VIKORSORT with TOPSIS-Sort and CODAS-SORT are consistent at least 90% of the time, demonstrating its efficacy in addressing multiple criteria sorting problems. Originality/value This work provides an integrative approach in evaluating tourist sites in view of tourism recovery during pandemics. The findings offer crucial insights for the primary stakeholders (i.e. government, tourist operators, and tourists) in planning, resource allocation decisions, and policy formulation. Policy insights are offered, as well as avenues for future works.

Multi-Criteria Decision Making (MCDM) is a complex process. It aims to support decision makers in making their decisions more effective and consistent. MCDM provides a useful and successful alternative for handling three main types of MCDM problems, namely, choosing, ranking and sorting. The first two are the most common problems studied but the third offers a way to deal with real world MCDM problems that require alternatives to be assigned to ordered categories. The practitioners are currently developing and applying sorting methods to solve problems from different application areas. In spite of its interest and applicability, there is only one previous review on Multiple-Criteria sorting, performed almost 20 years ago. Hence, because of its interest this paper presents a new and systematic review of MCDM sorting methods that includes 30 years of research in the field. This review has systematically analyzed the conventional and non-classical methods of MCDM sorting and then classified the papers published into 16 application areas. The analysis reveals that the methodological development is still in growth phase for MCDM sorting and discovers the applied methods’ trends. It also shows the complete spectrum of the areas of the application addressed, the state of knowledge about methods, the type of contribution to the knowledge, and the application area for the four categories of the MCDM approaches. The systematic review scrutinizes each selected article in order to find out which approach from the multi-criteria sorting presents the most development based on its contribution and application of the methods. We also aim to discover which Multiple-Criteria sorting methods are the most studied in MCDM. The relevant finding is the relation between the most applied methods and the application areas together with future directions for further research.
