Résumé :

To explore the contribution of marine resources to marine economic growth, this study uses panel data from 2006–2019 across 11 coastal provinces and cities in China and establishes threshold regression models using marine capital, labor, and science and technology as threshold variables affecting marine resources and economic growth. The findings reveal that the impact of marine resources on marine economic growth only demonstrates a single threshold effect under the primary industry marine resources; in general, with increased capital investment, the marine economy presents a positive development trend. The impact of primary and secondary marine resources on marine economic growth has a single threshold effect of labor input, while the impact of tertiary marine resources on marine economic growth has a double threshold effect of labor input. With investment in marine science and technology, marine resource development and utilization in the primary industries have played a consistent role in promoting marine economic growth. However, the impact of this role is gradually decreasing; marine resource development and utilization in the secondary and tertiary industries shows a development pattern wherein the driving effect of marine economic growth is first large, then small, and then large again. Based on the above analysis, China should promote the transformation of labor-intensive to capital-intensive industries by increasing investment in marine capital, training marine talent, and developing marine science and technology innovation to increase the development level of China’s marine economy.

Résumé :

The oceans are the world’s most important sources of biological activity, water, and biomass production. They supply food, oxygen, and other natural products critical for human existence, and interactions between the oceans and the climate. The oceans serve as the world’s greatest reservoir of biodiversity, including marine mammals, fish, crustaceans, molluscs, and countless species of zoophytoplankton. The ocean is a key source of organisms that are beginning to provide new and potent drugs for the treatment of human disease, as well as new products that use in biotechnology. Ocean can support human health, through providing new sources of drugs to treat human disease. Bioactive metabolites derived from marine organisms provide a rich source of chemical diversity that can contribute to design and development of new and potentially useful pharmaceutical agents. The marine ecosystem possesses efficient pharmaceutical materials to identify, isolate and characterize new compounds suitable for therapeutic purposes. Marine sponges, tunicates, fishes, soft corals, nudibranchs, sea hares, molluscs, echinoderms, bryozoans, prawns, shells, sea slugs, and marine microorganisms are sources of bioactive compounds. The current review is designed to collate all currently available data about the marine drugs with respect to sources, classification, chemical classes, metabolites of marine algae, fungi, bacteria and invertebrates, techniques for separation and isolation, and examples. This review aims to provide a holistic, multidisciplinary account of the current state of affairs on this topic.

Résumé :

This contribution considers the potential conflicts that may arise between customary rights and environmental rights in the face of dwindling marine resources. It sets the scene by reflecting on some of the common themes present in indigenous claims to marine resource by communities who were subjected to colonisation. In doing so it analyses the South African judgment, S v Gongqose Case No. E382/10 (unreported), which alluded to the existence of a customary right to fishing, a concept that has until now remained unexplored in South African law. This discussion is followed by a brief overview of the rapidly declining state of marine resources, worldwide and in South Africa. The note then considers the relationship between customary law and marine resources and some of the challenges in meeting rights-based customary claims to marine resources against the need to conserve a dwindling resource. It concludes by offering possibilities for reconciliation.

Résumé :

Abstract The implementation of marine spatial data management and decision support based on GIS provides a powerful tool for marine regulation. This study constructed a three-dimensional spatiotemporal data model of marine resources that is hierarchical, partitioned, and classified according to the management principle of using an underground resource layer, surface matrix layer, surface overburden layer, and management layer, taking the marine resource entity as the unit. Key research topics include marine multi-source information integration, visual expression, and spatiotemporal topology analysis for typical application scenarios such as sea area use, island development and utilization, and marine environmental monitoring and protection. The study developed a marine information decision support system with comprehensive integration and visual analysis of information on maritime islands, early warning and monitoring, the marine economy, and the marine environment. The system was applied to dynamic regulation of sea area use, spatiotemporal characteristic analysis of marine resources, the regulation of human activities in marine protected areas, and the monitoring of sea level rise. Practice has proved that a three-dimensional spatiotemporal data model of marine resources can meet the application requirements of “One Map”, the basic land and spatial information platform.

Résumé :

The Bajo Tribe constructs themselves as part of their environment; their identity is bound to their relationship with coastal and marine resources. They lived and owned the coastal and marine resources in Tomini Bay since the 1800s; however, it shifted when the state set conservation and concession policies since the 1980s. This research analyzed the coastal and marine resource policies and its impact on the ethnic identity of the Bajo tribe. The researchers applied the historical sociology approach and collected data through observation, interviews, and documentation methods. The result showed that the state policies regarding coastal and marine resources, which followed by the resettlement program to the land, caused the customary institution of the Bajo Tribe removed from its cultural roots. Conservation policy resulted in the territorializing of coastal and marine areas. Meanwhile, the concession policy of forest management permit and cultivation right on land had caused damage in coastal and marine resources due to overexploitation. These policies cause the loss of ethnic identity of the Bajo Tribe due to closed access and destruction of coastal and marine resources.

Résumé :

Marine resources have become a niche of life for fishing groups on the coast of Palabuhanratu Sukabumi, West Java. The dependence of the fishing groups on natural resources has led to competition in the process of obtaining resources. The purpose of this study is to analyze stakeholders in marine resource management in Palabuhanratu. This research was conducted in Palabuhanratu, West Java, Indonesia. The research employed a qualitative approach with 60 informants, divided into 20 local fishermen, 20 migrant fishermen, and 20 external fishermen. The results of the study show several analyzes of the research objectives. First, several actors have an interest and influence in marine resource management in Palabuhanratu, including government actors, local fishermen, migrant fishermen, external fishermen, and marine tourism. Migrant fishermen have a high interest and influence in the process of exploiting marine resources in Palabuhanratu. Second, the relationships that exist between actors in the interaction process for the marine resource management in Palabuhanratu can take the form of negotiations and conflicts. Conflicts that occur are in the form of destroying other fishing gear, controlling the area, and protesting, while negotiations occur in the form of a cooperative relationship between groups of fishermen in catching fish and agreeing on boundaries for each type of fishing gear.

Résumé :

This study identifies and describes the local wisdom carried out by the coastal communities, especially the people of North Seram, Maluku in preserving the island and marine environment as well as the customary institutions in determining and guarding local wisdom of coastal communities to manage marine resources. The marine resource is started to weaken along with the development of modern technology. This paper provides contemporary phenomena regarding the weakness of customary laws and traditional institutions that regulate marine resources, including social values in the form of rituals, representing the relationship between humans and their environment. The protection of marine resources around them will be an important discussion to see the role of government and society in preserving marine and coastal resources. This study used a qualitative approach to produce descriptive explanations from reports, book reviews, and documents that describe theories and information of both past and present. The result is that the local wisdom maintained as superior cultural practices that are beneficial to human survival, especially in maintaining the sustainability and balance between humans and living objects.

Texte intégral

Résumé :

Marine riparian areas and coastal vegetation are essential and important to the coastal marine ecosystem, although their interactions and functions are still unknown and ignored in marine ecological studies and integrated management planning. In southeastern Brazil, allochthonous resources derived from riparian Atlantic rainforests bordering rocky shores have been observed in abundance together with the shallow subtidal rocky reef benthos. In this study, we used stable isotopes (δ13C and δ15N) to characterize the main components in a benthic trophic web on a shallow tropical rocky shore, to identify the proportional contributions of allochthonous (marine riparian vegetation—MRV) to autochthonous (phytoplankton and algae) inputs and to test which basal food resources contributed most to the marine community on the Atlantic Forest–rocky coast interface. We found eight major food resources and seventeen consumers that we classified into different groups according to their feeding habits and biology. Although the main source of basal resources in the benthic trophic web in the present study remained autochthonous, the allochthonous resources were assimilated by all consumers. MRV is thus an important resource for some primary consumers and it should be included as a potential source of basal resources in marine ecosystems adjacent to marine riparian areas.

Résumé :

Historically, Inuit communities of the Arctic have relied significantly on the living marine resources of their coastal waters for nutrition, underpinning community cohesion and enhancing individual and collective well-being. Inadequate understanding of the conditions of coastal marine stocks and their dynamics, along with failed past fisheries management practices, now threatens secure access to these resources for food and nutrition. We examine the degree of integration of modern Canadian federal food and marine resource management policies, which heretofore have been unable to lessen food insecurity in the Arctic, suggesting that causes rather than symptoms need to be treated. Using evidence from Nunatsiavut, northern Labrador, we assess the limits to marine resource governance affecting access to traditionally important food sources. We explore the potential for both increased subsistence harvests and enhanced access to commercial fisheries in mitigating Inuit food insecurity, arguing for the relevance of expanded marine resource assessments, more focused fisheries management, and integration with policies designed to mitigate food insecurity. Crucially, the absence of methods for tracking changes in locally harvested marine resources threatens not only individual and household nutrition but also the social, economic, and cultural integrity of Inuit communities. We further describe the needs for monitoring and propose the use of indicators that capture the contributions of locally harvested marine resources to increased food security along with a framework that allows for utilizing local knowledge and observations. Relying on emerging lessons from research in Nunatsiavut, we build a foundation for a better understanding of both the political and institutional legacies that contribute to Labrador Inuit food insecurity and discuss how the deeper integration of food and marine resource management policies could help mitigate it.

Résumé :

With the over-exploitation of global resources and the increasing cost of developing land resources, marine resources have become the new choice for coastal countries to address resource problems. The development and utilization of marine resources encourages the growing of marine engineering equipment manufacturing industry. In this paper, we take Guangdong Province as the studied area, which has a natural advantage for the development of shipping and marine equipment industry, applying the mainstream industry competitive advantage theory – “diamond model” to build evaluation index system. And we calculate combining weights by AHP and variation coefficient method, as well as giving a comprehensive evaluation from the perspective of quantitative analysis for development of marine engineering equipment manufacturing industry in Guangdong Province. The results show that although Guangdong marine engineering equipment manufacturing industry achieves rapid development in recent years, the total scale amount of industry is small, shipbuilding industry development is slow, and professional technical personnel is inadequate. For these problems, this paper provides some suggestions for marine equipment manufacturing industry in Guangdong Province.

Résumé :

The total area of the Earth's oceans is 360 million square kilometers, accounting for approximately 71% of the Earth's surface area. It is a huge treasure trove of resources, containing abundant mineral resources, oil and gas resources, microbial resources, etc. The production of marine biomass is enormous, and as a third-generation renewable energy source, it has more sustainable development potential than terrestrial biomass. The main source of marine biomass is marine algae, so the development and excavation of marine algae resources is imperative. At present, alginate has become the second largest sustainable development resource in terms of production, second only to cellulose, and has enormous application value. The biological enzyme method for degrading alginate utilizes alginate lyase to β The elimination mechanism breaks the glycosidic bond, which has more degradation advantages than physical and chemical methods.

Texte intégral

Résumé :

As gas hydrate energy assessment matures worldwide, emphasis has evolved away from confirmation of the mere presence of gas hydrate to the more complex issue of prospecting for those specific accumulations that are viable resource targets. Gas hydrate exploration now integrates the unique pressure and temperature preconditions for gas hydrate occurrence with those concepts and practices that are the basis for conventional oil and gas exploration. We have aimed to assimilate the lessons learned to date in global gas hydrate exploration to outline a generalized prospecting approach as follows: (1) use existing well and geophysical data to delineate the gas hydrate stability zone (GHSZ), (2) identify and evaluate potential direct indications of hydrate occurrence through evaluation of interval of elevated acoustic velocity and/or seismic events of prospective amplitude and polarity, (3) mitigate geologic risk via regional seismic and stratigraphic facies analysis as well as seismic mapping of amplitude distribution along prospective horizons, and (4) mitigate further prospect risk through assessment of the evidence of gas presence and migration into the GHSZ. Although a wide range of occurrence types might ultimately become viable energy supply options, this approach, which has been tested in only a small number of locations worldwide, has directed prospect evaluation toward those sand-hosted, high-saturation occurrences that were presently considered to have the greatest future commercial potential.

Texte intégral

Résumé :

Sustainable utilization evaluation is the basis for ensuring the sustainable exploitation of fisheries’ resources. This paper explores the changes in the mean trophic level of African marine fish catches during a 70-year period based on the statistical data on marine fisheries’ catches in Africa from 1950–2019, provided by the FAO in, order to determine the sustainable utilization of Africa’s fishery resources. The results indicate that although the marine fishery resources of African coastal countries have great variability, their exploitation has roughly gone through the stages of under-exploitation, rapid exploitation, and over-exploitation. Currently, marine fisheries in North and Central Africa are characterized by sustainable exploitation, while East, West, and Southern Africa are in a state of overfishing. The study implicates that African countries should establish a real-time monitoring system for marine fishery resources as soon as possible in order to dynamically grasp the actual changes in fish community structure due to fishing activities, ensure transparency in management and decision making, enact marine regulations to restrict massive fishing by overseas fleets, issue fisheries licenses cautiously, adopt conservative resource conservation policies, and enforce actions to achieve sustainable fisheries development.

Résumé :

Rare earth metals are an important strategic resource. Due to scarce reserves, and large consumer demand, it is facing the crisis of resource depletion. Marine are the largest deposits sites in the world. In the long growth history, marine autogenic sedimentary mineral, such as polymetallic nodules, crusts with large quantities, not only contain the enrichment of Mn, Fe, Co, Cu, Ni and other valuable metals, but also contain extremely rare earth elements (REE) in the crust. Thus, in the process of developing marine mineral resources, Mn, Fe, Co, Cu, Ni and other metals are used, while it is possible for the development and utilization of the associated rare earth mineral. Marine may become a new field of rare earth resources development.

Résumé :

The aim of research to determine the potential and use of marine resources, describe the values of local wisdom that have relevance to the management of marine resources, and describe forms of marine resource management. The research method used is survey method, by conducting in-depth interviews and focus group discussions. The research location is located in Kei Island conservation area, Pulau-Pulau and the surrounding waters, Southeast Maluku Regency. Data were analyzed descriptively qualitative by describing all variables examined clearly and accurately. The results showed that the Kei Islands have incredible potential of the region, has the potential of fisheries and aquaculture is quite high and the fishery management area of strategic importance. The management of the area with the local wisdom approach of the community is carried out for generations, namely the culture of the sea and the culture of eating together. Local wisdom that is run so far strongly supports the determination of watershed conservation area. The forms of marine resource management in the conservation area is still governed by the rules verbally as is customary informal. The threat to the conservation of marine resources need to be aware through an integrated supervision sustainability of marine resources in order to remain protected, conservation and sustainable development.

Talaat WIAW, Md Juhari S, Esa N, Che Lah S, Mohamad M. 2018. Traditional ecological knowledge in conserving marine resources in Terengganu, Malaysia. Nusantara Bioscience 10: 6-11. Conserving marine resources to ensure its sustainable supply requires concerted effort by all the stakeholders including the local fishermen. The zoning of MPAs by the government is a formal method of conserving marine resources where some efforts of conservation on the specified areas are demonstrated. Currently, in the Terengganu waters, which sits in the southernmost part of the South China Sea, the only MPAs are the 13 islands/areas zoned as marine parks amounting to 568.69km2. Nonetheless, protecting or conserving marine resources cannot be limited to areas surrounding these marine parks alone. With 244km coastline and fishing is inherently a major economic activity in the state, more areas in the Terengganu waters should be designated as MPAs or alternatively gazetted as ecologically sensitive areas. In order to conserve marine resources to ensure its sustainable supply, a concerted effort must be carried out by all the stakeholders including the local communities, whose livelihood are directly impacted. As repositories of knowledge with regard to biodiversity, habitats and their seasonal fluctuations, the local communities must also be appreciated as resource users. The local fishermenâ€™s TEK including familiarity with the use of sustainable fishing methods and practices are indeed pertinent for the sustainable supply of marine resources. This paper discusses the existing marine conservation efforts in Terengganu as well as explores the possibility of factoring in the local communitiesâ€™ local knowledge through collaborative management to enhance these efforts.

Résumé :

Maritime and marine development targets are very realistic considering the position of Indonesia is geographically located and has a comparative advantage because it is very close to the world market. On the other hand, Indonesia is located in the tropics with thousands of islands have a wealth and maritime and marine resource potential is very large. Awareness of the protection and preservation of the marine environment began to grow among the countries participating in the Convention; especially regarding the exploitation of natural resources is carried out on a large scale in the marine environment. Especially for marine areas that are still in dispute, the power of sharing activity is the distribution of marine resources with the agreement Joint exploitation the original problem as a potential source of conflict, transformed and directed into a source of cooperation. Such cooperation generally includes the exploration, exploitation, and sharing of benefits derived from the exploitation of natural resources in the region for the parties.

Résumé :

Abstract Co-management is a system in which resource management responsibilities are shared between the state and user groups. Various national and provincial-level governments separately manage resources along the coastal and marine areas of Pakistan. The country’s existing policy framework is devoid of an integrated management approach, where the participation of real stakeholders in the decision-making process is either disregarded or missing. Therefore, the present study highlights the internal and external constraints of coastal and marine resources management issues in Pakistan and discourses the problems that halt the participation of stakeholders in the decision-making process. This research also confers the potential of a co-management framework through which the coastal and marine resources management structure can be organized to deliver local sustainability in the country. The adoption of a co-management approach in Pakistan’s coastal and marine areas would help to improve the protection and conservation of natural resources via share-based responsibility. Additionally, it provides a baseline to coastal and marine planners in the country to adopt share-based responsibility for resources management to mimic the conflicts amongst users to the environment, and those affected by the decisions can agree to understand or accept common intertwined resources.

Résumé :

Extreme concentration of marine biodiversity and exploitation of marine resources in the Coral Triangle pose challenges to biogeographers and resource managers. Comparative phylogeography provides a powerful tool to test biogeographic hypotheses evoked to explain species richness in the Coral Triangle. It can also be used to delineate management units for marine resources. After about a decade of phylogeographical studies, patterns for the Coral Triangle are emerging. Broad connectivity in some species support the notion that larvae have maintained gene flow among distant populations for long periods. Other phylogeographic patterns suggest vicariant events resulting from Pleistocene sea level fluctuations, which have, at least occasionally, resulted in speciation. Divergence dates ranging back to the Miocene suggest that changing land configurations may have precipitated an explosion of species diversification. A synthesis of the marine phylogeographic studies reveals repeated patterns that corroborate hypothesized biogeographic processes and suggest improved management schemes for marine resources.

Résumé :

Abstract The sea is an important aspect of development in bay areas. Coordinated development of the marine resource environment and social economy is an inevitable requirement for high-quality development of the marine economy. This paper builds an index to evaluate the coordination of marine resources, environment and social economy in bay areas from four aspects: resource and environmental effects, resource utilization compliance, socio-economic development conditions, and technological investment and development status. The model is implemented for Taizhou Bay. The results show that the overall level of coordination between its marine resource environment and social economy is poor, under 0.4. The main reasons for this situation are the decline in environmental quality of bay resources, and insufficient technological investment and development. In view of the problem of uncoordinated regional development, this paper puts forward two suggestions to provide technical support for the high-quality development of Taizhou Bay: implementation of land and sea resource control, and increased investment in environmental repair technology in the bay.
