Oceans, seas, lakes and other waterbodies are increasingly suffering from too much plastic waste. Numerous sources are contributing to this plastic waste problem. Additionally, conventional fishing nets, made out of nylon, are causing environmental damage by disintegrating into microplastics. The breakdown process stops there, as these microscopic particles are non-biodegradable. Microplastics remain in waters for years causing harm to marine organisms that ingest them. Linen fishing nets are a valid alternative and more ecological production of nets. This study aims to compare the costs of these new linen nets with conventional nets. These costs can be related to the environmental benefits of these alternative nets. The research objective is to study the question under which conditions it would be optimal to choose linen nets over conventional (nylon) fishing nets. The conditions examined are economic and policy, environmental and technological. This research question is put into the wider context of microplastics. A rotation model, typically used in forest economics, is applied to analyze the optimal lengths of periods to renew both a linen and a nylon fishing net. A comparison of the costs is conducted and a subsidy-based policy instrument is determined for the fishers using linen nets.

A subsidy-based policy could be applied to make fishing enterprises in Finland use ecological fishing gear. The results suggest that the costs of such a policy would be reasonable, estimated between €1.1 and €4.5 million in this study. Importantly, an increase in the use of ecological nets would lead to a decrease in the total microplastic load in waterbodies.

Caribbean countries, including Jamaica, face substantial risks from storms and hurricanes. Coral reefs, mangroves, and seagrass beds protect communities from storms, and are critical for the sustainability of many economic activities, jobs, and inclusive growth.

A recent report, “Forces of Nature,” examines the considerable flood risk reduction services that mangroves provide to Jamaica, together with benefits related to fisheries production, and carbon sequestration.

This report supports the growing interest within the development agenda to include nature-based solutions for disaster risk management and provides vital information for discussion on climate change adaptation and mitigation, insurance, and disaster recovery decisions.

Payments for Ecosystem Services (PES) have emerged as a popular conservation tool, yet evaluation among different PES programs strategies remains piecemeal. We prospectively compare cost-effectiveness of general PES, collective payments for ecosystem services (CPES) and the transition from PES to Land Purchases or Easements (LPE). We analyze the economic cost using statistics data and literature data, and analyze the transaction cost with the ordinal variable. We develop the Emergy Analysis method with the InVEST Habitat Quality model, and utilize it to analyze and map the ecological effectiveness. This paper gives an example to assessing the cost-effectiveness of different PES programs. Based on the analysis, LPE strategy led to improved ecological effectiveness, lower cost and greater cost-effectiveness. The collective PES has lower cost than general PES. However, they demonstrate equal ecological effectiveness. Based on these outcomes, we analyze the factors that influence PES programs’ cost-effectiveness, including collective or group, market-based mechanism, economic incentive, transaction cost, contract scale etc. We conclude that minimal number of intermediaries, community/collective support and involvement constitute the key factors in improving the cost-effectiveness of ecological programs. However, we acknowledge the need for further studies on the subject.

The papers in this special issue provide new insights into ongoing research to value coastal and marine ecosystem services, and offer meaningful information for policymakers and resource managers about the economic significance of coastal resources for planning, restoration, and damage assessment. Study areas encompass a broad geographic scope from the Gulf of Mexico in the United States, to the Caribbean, the European Union, Australia, and Southeast Asia. The focus of these papers ranges from theoretical perspectives on linkages between ecosystem services and resource management, to the actual integration of valuation information in coastal and marine resource policy decisions, and to the application of economic valuation methods to specific coastal and marine resource management problems. We hope readers will appreciate these new contributions to the growing literature on coastal and marine resource ecosystem services valuation.

The technology-driven application of big data is expected to assist policymaking towards sustainable development; however, the relevant literature has not addressed human welfare under climate change, which limits the understanding of climate change impacts on human societies. We present the first application of unique mobile phone network data to evaluate the current nation-wide human welfare of coastal tourism at Japanese beaches and project the value change using the four climate change scenarios. The results show that the projected national economic value loss rates are more significant than the projected national physical beach loss rates. Our findings demonstrate regional differences in recreational values: most southern beaches with larger current values would disappear, while the current small values of the northern beaches would remain. These changes imply that the ranks of the beaches, based on economic values, would enable policymakers to discuss management priorities under climate change.

Marine plastic pollution is heavily driven by escaped plastic waste from land. Effectively reducing flows of plastic pollution into the oceans requires incentivizing efficient disposal decisions, discouraging production and consumption of products with low recyclability and reuse potential, and encouraging lower-impact, easily recyclable product and packaging designs. We examine the economic literature on waste management and integrated environmental policy to assess how particular policies target these individual pathways and can efficiently reduce flows of plastics into waterways. These policies include production/retail bans and standards, extended producer responsibility, price-based policies such as advance disposal fees and two-part instruments, and interventions grounded in behavioral economics and psychology. We also consider the applicability of these policies in coastal developing nations that often rely upon the informal sector for waste management services. We conclude by identifying important issues for future research.

The natural capital of the vast deep ocean is significant yet not well quantified. The ecosystem services provided by the deep sea provide a wide range of benefits to humanity. Proposed deep-sea economic activities such as fishing, deep-sea mining and bioprospecting therefore need to be assessed in this context. In addition to quantifying the economic benefits and costs of such activities on their own, their potential impact on the deep-sea natural capital also needs to be considered.

This article describes such a natural capital approach, identifies relevant ecosystem services and looks at how a range of proposed commercial activities could be assessed in this context. It suggests a methodology for such analysis and suggests an approach to a sustainable blue deep-sea economy that is consistent with environmental precaution. It will close with suggestions of how potential risks can best be handled.

The article aims to show that modern environmental economics based on natural capital can provide a useful framework for deciding future deep-sea efforts.

The number of recreational fishing licenses in Brazil has been increasing exponentially since 2000, but a drop occurred in 2014, probably associated to an economic crisis. On average, only 20% of the licenses issued in 2011-2014 were for anglers fishing in marine waters. From those, 20% were type A licenses (shore-based) and the remainder were type B-C licenses (boat-based). Based on the licenses database, it was possible to estimate a mean annual expenditure by marine anglers of US$ 524 million between 2011 and 2014. The absolute mean expenditure per trip was usually higher for men but women tended to spend more as a percentage of their income. This was mainly due to the lower average income of women relative to men. Some inconsistences in the licenses database were found which could be easily corrected in the future and the estimates presented here improved.

Coastal cities continue to experience rapid urbanisation and population growth worldwide, linked to the diverse economic and social benefits flowing from proximity to the sea. Growing concern over human impacts upon coastal waters and global strategic goals for healthier cities requires that coastal cities develop innovative ways to inspire and empower communities to embrace and cherish city seascapes. Coastal city communities have much to gain from a healthier relationship with the sea. This paper proposes a collaborative community-led marine park concept that celebrates a city's connection to the marine environment, enhances sustainable economic prosperity and enables communities to participate in activities that deepen understanding, value, care and enjoyment of the city seascape. A city marine park (CMP) is not a marine protected area because it does not have biodiversity and heritage protection or ecosystem governance as a primary goal and does not aim to restrict human activities. A CMP enables city communities to collaborate towards a shared vision of elevated status and value for the city seascape. A CMP considers socio-economic and geographical context, including land-sea connectivity, and is integrated within a coastal city's strategic urban planning. This paper highlights core themes of a CMP and the diverse and wide-ranging benefits from coordinated activities that better connect the city community with its seascape. If co-created by the coastal city community and civic leaders, a CMP will form an enduring spatial nexus for progress toward healthy cities addressing multiple interlinked global sustainable development goals.

Predicting ecosystem components in the Gulf of Mexico and their responses to climate variability with a dynamic Bayesian network model

The Gulf of Mexico is an ecologically and economically important marine ecosystem that is affected by a variety of natural and anthropogenic pressures. These complex and interacting pressures, together with the dynamic environment of the Gulf, present challenges for the effective management of its resources. The recent adoption of Bayesian networks to ecology allows for the discovery and quantification of complex interactions from data after making only a few assumptions about observations of the system. In this study, we apply Bayesian network models, with different levels of structural complexity and a varying number of hidden variables to account for uncertainty when modeling ecosystem dynamics. From these models, we predict focal ecosystem components within the Gulf of Mexico. The predictive ability of the models varied with their structure. The model that performed best was parameterized through data-driven learning techniques and accounted for multiple ecosystem components’ associations and their interactions with human and natural pressures over time. Then, we altered sea surface temperature in the best performing model to explore the response of different ecosystem components to increased temperature. The magnitude and even direction of predicted responses varied by ecosystem components due to heterogeneity in driving factors and their spatial overlap. Our findings suggest that due to varying components’ sensitivity to drivers, changes in temperature will potentially lead to trade-offs in terms of population productivity. We were able to discover meaningful interactions between ecosystem components and their environment and show how sensitive these relationships are to climate perturbations, which increases our understanding of the potential future response of the system to increasing temperature. Our findings demonstrate that accounting for additional sources of variation, by incorporating multiple interactions and pressures in the model layout, has the potential for gaining deeper insights into the structure and dynamics of ecosystems.
