This study assesses trace metals and macro benthic fauna in a dumping area for dredged material in the continental shelf of Guanabara Bay (Rio de Janeiro), southeast Brazil. Sampling of the study area was made after the last dredging of Rio de Janeiro, in 2017, removing 2.9 × 106 m3 of sediments that were disposed at a recurrent dumping site. The trace metals Cu, Zn, Pb, Cr and Ni exhibited a pattern

This paper aims to discuss the evolution of marine spatial planning policies for mariculture in China. Word frequency analysis was used to analyze the evolution of marine spatial planning (MSP) policies. The marine spatial planning policies for mariculture in China since 1988 were divided into three periods: the production period, the integrated management period and the sustainable development period

Although Vietnam's coastal and estuarine areas are most vulnerable to the impact of climate shocks, very few studies have closely evaluated this vulnerability. This research applied the Livelihood Vulnerability Index (LVI) and the United Nations Intergovernmental Panel on Climate Change vulnerability framework (LVI-IPCC) to estimate the climate vulnerability of small-scale fisheries in the Tam Giang

Seawater desalination is an expanding procedure to supply coastal regions with freshwater. Such developments introduce a significant amount of brine effluent into marine environments and highlight an important global need to minimize associated impact on marine environment. We review the measures adopted to manage the impacts of brine discharge in Spain by analyzing published and gray literature and

The small-scale fishery has a high socio-economic importance in the Mediterranean Sea. This is especially relevant for specific areas that harbor, proportionally, very large part of the fleet, and thus, represent hot spots. Among such areas, Kalymnos Island merits special attention as it harbors the largest and most active small-scale fleet in the eastern Mediterranean. Therefore, the present study

Rebuilding fish populations worldwide is urgently needed, but socio-economic concerns often slow down or even prevent the process of rebuilding fish stocks. To address this concern we conduct an economic analysis of rebuilding six depleted Canadian fish stocks under different biological and management scenarios. Rebuilding scenario projections are based on underlying fish stock assessments and fish

While interactions between regular wave driven flooding and reefs have been widely studied due to climate change pressure, the effects of reefs on tsunami flooding have less been investigated. From studies of historical events, reefs can behave as buffers or as amplifiers of inundation, depending upon the location. Interactions between reefs and tsunamis have generally been analyzed with idealized

The present study attempted to estimate the value of the environmental improvement programs using a CVM model. The CVM model included economic variables, socio-demographic variables, and proxy variables measuring survey participants' familiarity with the coastal areas. We conducted an online survey during August 2018 with 3428 participants and received 1000 usable responses (final response rate of

Selective removal of problem individuals following shark bite incidents would be consistent with current management practices for terrestrial predators, and would be more effective and more environmentally responsible than current mass-culling programs. In parallel, and in addition to traditional forensics analysis, we recommend the routine collection of shark DNA from wounds or devices following shark

When the first Norwegian commercial catch of snow crabs was taken in the Barents Sea in 2012, an unexpected opportunity arose to create a new, profitable natural resource-based industry. However, hidden under the surface were massive biological, technological, and institutional uncertainties. This study first explores what motivated the entrepreneurs to invest in an industry exposed to extreme uncertainty

Economic analysis is well suited to inform protected resources management in marine and coastal environments. The purpose of this review is to provide a connection between the challenges facing managers of marine protected resources and specific forms of economic analysis that can help address them. We identify and illustrate several common protected resources management challenges including scarcity

Worldwide, biological invasions remain an unrelenting environmental disaster. In the last years, the Indo-Pacific lionfish, Pterois volitans, has become one of the most highly surveyed biological invasions in Western Atlantic Ocean. This predator fish has the potential to affect the invaded ecosystem due to its voracity, fast population growth, and strong competition with native fauna for resources

The high degree of uncertainty associated with the extent of future sea-level rise stems primarily from the potential mass loss of the Greenland and Antarctica ice-sheets. We explore the impact of this uncertainty on economic damage due to sea-level rise for 136 major coastal cities. We compare the probability distribution for damage under the assumption of no adaptation for two relative sea-level

Seaweed invasions have been plaguing coastal ecosystems in countries bordering the Atlantic Ocean since 2011. To protect their coastal fisheries and tourism, several countries in West Africa have adopted seaweed cleanup policies to periodically remove invasive seaweeds from the beach, but funding remains a challenge. We conducted a contingent valuation study in Ghana to understand the drivers of public

Ghost fishing, the ability of fishing equipment to continue to capture organisms even after it is no longer controlled, leads to serious marine impacts, including bycatch, which contributes to biodiversity loss. Insistent complaints from artisanal fisher in the state of Bahia, Brazil, concerning the impacts of nets lost or abandoned by fisher from other regions that operate in their traditional fishing

As competition increases, so does the need for a destination to differentiate itself. Blue Flag, a voluntary environmental certification, has been described as an effective marketing tool to communicate nature-based management to consumers. Does certification, however, influence the consumer's choice when choosing a destination? This study examined consumer's satisfaction of beach characteristics and

The characteristics and duration of the processes occurring from the design and designation of a Marine Protected Area (MPA) to the effective implementation and renewal of its management plan were analysed in 234 MPAs from four countries in the North-east Atlantic Ocean (France, Portugal, Spain and England). These MPAs were managed by 118 plans and each one could be applied to between one and 11 MPAs

The viability of Mediterranean marine fisheries is increasingly under threat due to the low biological productivity of overexploited stocks, low economic performance of the fishing units, and offer of unattractive jobs, among other. This has resulted in a decrease of 30% in the number of fishing units active in European Union Mediterranean fisheries over the period 1995–2016. The detailed causes for

North Atlantic right whales (NARW) are one of the most endangered marine animals with a global population of ~400 individuals left. Recent climate-driven shifts in distribution have significantly increased their mortality risk from human activities. After twelve NARWs died in the Gulf of St. Lawrence in 2017 from fishing gear entanglement and ship strikes, Canada adopted measures designed to decrease

Although attribute non-attendance (AN-A) in choice experiments (CEs) conducted in developed countries has received increasing attention, fewer researchers have studied this issue in developing countries. This paper presents a study on residents' willingness-to-pay (WTP) to dispose of Enteromorpha prolifera and restore damaged costal resources in Qingdao, China. Specifically, a five-level design of

Climate change-driven ocean acidification (OA) is causing rapid change to global ecosystems and poses a significant threat to marine life. However, predicting ecosystem effects remains highly uncertain and governance responses to OA are not yet forthcoming. Adaptive governance can provide a means to deal with this uncertainty and we consider its application to the polycentric governance of adaptation

Marine Spatial Planning (MSP) has been heralded as the key means of achieving a more integrated approach to marine use across sectors and spatial scales. Achieving greater integration and coherence in MSP governance arrangements is seen as a way to resolve current problems of marine governance (such as fragmentation) and address future resource demands in a sustainable way. However, there is a lack

Cultural heritage-specific research is scarce within the climate change literature and climate change policy documents, challenging climate adaptation efforts to minimize adverse impacts on cultural heritage. Engaging and assessing diverse stakeholders' values and integrating those with evidence-based knowledge is critical for timely, effective and transparent preservation and climate adaptation of

Portsmouth Harbour was used to investigate the effects of fresh water flow and water physio-chemical properties such as salinity on turbidity and dissolved oxygen within industrialised Macrotidal estuaries. Nine sites were selected within the harbour for field sampling and data collection based on their contrasting hydrodynamic environment and accessibility from land. Sediment, water samples and water
