Introduction of invasive species through ballast water discharge has been a serious concern with the marine ecosystem. With growing research in the ballast water management, recent studies are being focused on the types of invasive species and physico-chemical parameters discharging into ports. Different treatment and management strategies have been internationally implemented in ships in accordance

Uncontrolled expansion of urban areas over mangrove systems is a historical threat for conservation and restoration of coastal landscapes. In Brazil, a country that presents one of the largest mangrove areas on the planet, recent political changes considered mangroves as “Permanent Preservation Areas” with the environmental function of preserving their ecosystem services. Under this regulation, mangrove

This study analyzed decadal and regional trends in one type of shore protection method: beach nourishment, since its beginning in the U.S. nearly 100 years ago. While strategies such as managed retreat may be more feasible in the long-term, beach nourishment is a dominant method of shore protection in the U.S. today. During the last century, the beaches of over 475 U.S. communities have been restored

The issue of seafood waste has been gaining attention globally due to the increasing demand for seafood, its negative impacts on the environment, and its implications for marine conservation and policy. This study examined seafood waste in Namibia, a country with a large commercial fishing industry but limited baseline data on seafood waste. To gain insight into seafood wastage and waste management

Collaboration in a natural resource management setting is vital to effective management. This paper evaluates collaboration and information and data exchange among organizations involved in the management of the Lower Mekong River Basin (LMB). As in other major river basins throughout the world, the LMB faces complex management challenges related to transboundary cooperation and competing demands from

La Rochelle marina, in the south-west of France, is one of the largest recreational port in Europe. As many ports around the world, La Rochelle marina is not spared by siltation and has to face serious dredging operations over a period of 8 months per year. Consequently, there is a big interest in determining sediment fluxes in the area and implementing measures to minimise siltation and/or to optimise

Marine protected areas (MPAs) have been implemented to reduce negative impacts of human activities on marine life. However, many MPAs do not address boat traffic and the behavioral alterations and physical injury to marine organisms that may result. Boating activities can alter activity patterns, increase stress, and lead to physical injury in various aquatic animals. The Sandy Bay West End Marine

Anadromous sea lamprey (Petromyzon marinus Linnaeus, 1758) uses many environments in its life cycle, which makes them even more susceptible to any environmental changes. Due to the potential of local ecological knowledge (LEK) in fishing villages on the Minho River, this study provided information on trophic chain, conservation, gastronomy, taboos, and food aversions of the sea lamprey. The discharge

Beyond the boundaries of national jurisdiction, the ocean floor and its minerals are governed by a comprehensive international regime, which determines by whom and under what conditions these natural resources can be prospected, explored and exploited. The main principles are set out in the United Nations Convention on the Law of the Sea and the 1994 Implementation Agreement, while more detailed rules

Ensuring a balance of conservation and human activities within the marine environment requires complex decisions on how to achieve conservation objectives whilst considering the likely economic and social costs and benefits of such decisions. We assessed the risk of adverse effects from abrasion caused by bottom fishing, as a case study, to demonstrate an integrated spatial management methodology.

Shoreline armoring has repercussions on coastal processes, including reducing the width and height of sandy beaches, which affect coastal ecosystems and ecosystem services. This project, consisting of two parts, was carried out in the Canadian province of Quebec, on the coasts of the St. Lawrence Estuary and Gulf, which cover the territory of 21 coastal Regional County Municipalities (RCM). The objectives

The aim of this paper is to analyse to what extent the recognition of sustainable management of coastal resources may act as a driver of local economic growth. To this end, the importance of Blue Flag certification in promoting the development of a local tourism sector is analysed. Using a natural experiment based on some localities increasing the number of their certified bathing areas through recognition

Coastal protection refers to measures that seek to reduce damage to coastal land and assets from natural hazards such as erosion and inundation. Coastal population growth and projected climate change impacts will expose more people, land and assets to erosion and inundation increasing demand for coastal protection. Established coastal protection funding approaches, such as general taxation, intergovernmental

Recreational boating is increasingly popular and provides social and economic benefits, but can also have ecological impacts, including damage from anchoring on sensitive seabed habitats like coral reefs. Mooring buoys are commonly used to manage anchoring activity, and I tested whether they moderated anchoring on coral reefs in the British Virgin Islands. A spatial survey revealed that overall boat

Land-sea interface is an ecotone where the intersection of marine and terrestrial ecosystems create unique ecological conditions for terrestrial mobile species and freshwater-adapted organisms to exploit marine-derived food resources. Mammalian carnivores play an important role in almost any ecosystem where they live due to their top-down (or trophic cascade) effects on prey species and primary producers

Eastern Baltic cod is an example of a fish stock where fishing pressure has substantially declined after decades of intensive exploitation. However, in contrast to the expected improvements in stock status, stock productivity has concurrently declined to a historic low level. Targeted fisheries for the eastern Baltic cod were recently banned. However, at present low growth and high natural mortality

The push and pull between innovation and conservatism is a normal situation in Dutch coastal governance. In some cases this leads to conflicts over which policy solution to choose. This paper argues that coastal governance processes are shaped by policy frames. They influence what actors consider the policy problem, the appropriate solution, and the way to achieve this solutions. The paper features

Island tourism is an important part of marine tourism and has developed into an important part of international tourism consumption. The island tourism environment is the foundation for the sustainable development of island tourism. This paper takes Koh Lan as the research area to conduct a questionnaire survey among international tourists to understand their perception of the tourism environment of

The world's oceans are subject to the multiple impacts of human activity and to the consequent threats to the health of many and varied ocean ecosystems. Oceans around South Africa are no exception and, with the need for economic growth in the country, anthropogenic stressors on ocean resources are rapidly increasing. In this study, we investigated 14 different anthropogenic stressors that impacted
