Long-term sustainable port development requires accounting for the intrinsic values of ecosystems. However, in practice, ecosystem considerations often only enter the planning and design process of ports when required by an Environmental Impact Assessment. At this late stage, most of the design is already fixed and opportunities to minimize and restore ecosystem impacts are limited. In this paper, we adopt a large-scale, ecosystem perspective on port development with the aim to identify ecosystem-based design alternatives earlier and throughout the planning and design of a port’s marine infrastructure. We present a framework, termed the ‘ecosystem-based port design hierarchy’ (EPDH), to identify ecosystem-based alternatives at four hierarchical design levels: 1) alternatives to port developments, 2) port site selection, 3) port layout design, and 4) design of structures and materials. In applying the EPDH framework retrospectively to a case study of port expansion in Tema, Ghana, we establish that ecosystem considerations played only a limited role in identifying and evaluating alternatives at all four design levels in the case study, whereas more eco-friendly alternatives in terms of port layouts, structures, and materials are identified using the EPDH framework. This reveals that opportunities for ecosystem-friendly port designs may have been missed and demonstrates the need for and the potential added value of our framework. The framework can assist practitioners in earlier and wider identification of ecosystem-based alternatives for a port’s marine infrastructure in future seaport developments and, hence, represents an important step towards more sustainable port designs.

Abstract Under the new normal of China’s economy, the competition among the port enterprises is not only the competition of the core competence of the port, the port industry chain or the port supply chain, but also the competition of the port service ecosystem. In this paper, the concept and characteristics of the port service ecosystem is discussed, a hierarchical model of the port service ecosystem is constructed. As an extended logistic model, Lotka-Volterra model is applied to study the competitive co-evolution and mutually beneficial co-evolution of enterprises in the port service ecosystem. This paper simulates the co-evolution of enterprises in the port service ecosystem by using MATLAB programming. The simulation results show that the breadth of the niche of the enterprises is changing with the change of the competition coefficient and the coefficient of mutual benefit in the port service ecosystem. Based on that, some proposals are put forward to ensure the healthy and orderly development of the port service ecosystem.

Ecosystem services of the marine environment can be considered as ecological, economic and social components of sustainable development, but at present, they are not fully evaluated. In this regard, the article sets the task of identifying and valuing ecosystem services in port waters. As a result of the study, the attribution of the benefits created by the port waters to the ecosystem services of the marine environment is justified, their division into two categories is carried out—into providing and supporting services, a methodology for their cost estimation is proposed. It is proposed to calculate ecosystem services by the amount of port water rent, which is understood as the residual income in port activities after deducting from it all costs and profit margins on fixed assets of port infrastructure. According to this methodology, calculations of the total cost of ecosystem services of port water areas for Russia as a whole and specific values of the cost of ecosystem services per 1 km² of port water area for all seaports of the country were carried out. Supporting services are proposed to be assessed by the rent of assimilation potential formed when compensatory measures are not carried out for environmental damage caused by port activity. According to the results of calculations, it was revealed that the total port rent is approximately 33–38 billion rubles. At the same time, payments for the use of water resources in the waters of seaports entering the budget system amount to an insignificant part of this value—0.17 %, which indicates the inefficiency of the current payment system. To correct the situation, an algorithm for calculating fees for ecosystem services in port waters with the inclusion of an environmental component is proposed, the maximum share of port water rent (10 %) is justified, without disturbing the balance between the state and private structures. The significance of the work carried out is to substantiate a new category of ecosystem services of the marine environment, ecosystem services of port waters, and to show the possibility of using their valuation for management purposes, including through the formation of additional budget revenues.

There is a gradual but clear transition towards a circular economy (CE) that will potentially have significant impacts on ports, both in their function as transport nodes and as locations for logistics and manufacturing activities. A rough appraisal of new investments in circular manufacturing activities in ports in Europe drawn from organizational reports and official webpages illustrates the (slow) development of circular activities in ports. This paper is to our knowledge the first paper which deals with the implications of CE for the business model of the port development company. We assess if and how the circularity transition affects the role and business model of port authorities as developers of port clusters. We outline a framework for analyzing the consequences of CE on the business model of the port authority. We then apply this framework to get a detailed understanding of the emerging CE ecosystem in the Port of Amsterdam, which is clearly a frontrunner in the transition, and the role of the government-owned Port of Amsterdam port development company (PoA) in developing this ecosystem. In Amsterdam, a CE ‘business ecosystem’ has emerged and continues to evolve with three types of synergies between the companies in this ecosystem: logistics infrastructure and services synergies, input–output synergies and industrial ecology synergies. We find that the spatial scale of the CE value chains in the port varies between segments and that they are generally less international than ‘linear’ value chains. The development of CE activities occupies a central place in PoA’s strategy, and PoA assumes new and active roles in advancing the circular business ecosystem, most notably through developing industrial ecology synergies and nurturing and attracting new, innovative CE companies. Finally, the circularity transition leads to changes in PoA’s business model, with an increasing focus on new services that create synergies, and a decreasing importance of the share of port dues in the total revenue mix.

This research examines the issue of why Co-Fish Project is important for the ecosystem in the Tegal Port area and how the project was implemented during 1998-2005 and the impacts of the project on fishing communities. It is used as a historical method with the ecosystem approach because Co-Fish Project intended to maintain, improve, and develop the benefit value and the ecosystem function for the progress of all elements or stakeholders in the ecosystem. The research results show that Co-Fish Project in Tegal City is an integral part of the Coastal Fishing Port (PPP) construction project and the development of the Tegalsari Fish Landing Base (PPI) of Tegal City. Co-Fish Project as a central government project under the coordination and management of the Indonesian Ministry of Maritime Affairs and Fisheries with ADB funding sources requires the development and empowerment of the port area ecosystem as an instrument to support the development and sustainability of port activities. It is important because the condition of the existing slum port area is not organized with the socio-economic life of fishermen with high poverty levels and prone to conflicts among the fishermen. The implementation of the Co-Fish Project has a positive impact on reducing poverty and fishermen conflicts due to improvements in infrastructure, sanitation, and the development of fishermen's socio-economic institutions and the port area ecosystem synergizing with the increasing fishermen's income and social harmony.

Исследование, проведенное на основе теоретико-методологического подхода с позиции потенциального потребителя, связано с постановкой вопроса о предпосылках и перспективах формирования цифровой экосистемы непрерывных образовательных тренингов. Данная экосистема, позволяющая совместить интересы рынка труда и профессионального образования, предполагает создание сети образовательно-профессиональных площадок (онлайн-хабов) с использованием традиционных и платформенных цифровых носителей, объединенных в «гибридную» инфраструктуру, а также с учетом новых экономических реалий. Непрерывные профессионально-образовательные тренинги затрагивают интересы в первую очередь лиц трудоспособного возраста и нацелены на сохранение трудовой занятости и снижение рисков безработицы на региональном уровне. Существующий разрыв между низкой производительностью труда и опережающей индексацией бюджетных доходов, невысокими доходами молодых работников и неконкурентоспособными программами дополнительного профессионального образования может быть компенсирован с помощью цифровой экосистемы непрерывных профессионально-образовательных тренингов, направленных на формирование опережающих компетенций. Они смогут привлечь на рынок труда молодых трудоспособных лиц как основных производителей валового регионального продукта. Положения и выводы статьи основаны на зарубежном передовом опыте и отечественных образовательных стратегиях по созданию модели новой образовательной экосистемы. This research is made with a theoretical-methodological approach from the perspective of the consumer. It is related to the question of the prerequisites and prospects for the digital ecosystem of continuous educational training formation. The new educational ecosystem brings together the interests of the labour market and professional education using a network of educational and professional platforms (online hubs), which is built upon a “hybrid” infrastructure of traditional and platform digital media, taking into account the new economic realities. The continuous vocational trainings focus on persons of working age, young people, and are aimed at maintaining employment and reducing the risks of unemployment at the regional level. The establishment of a digital ecosystem of continuous vocational training to form outpacing competences can compensate for the gap between low labour productivity and outpacing budget income indexation, low staff rotation, low incomes of young workers and lack of competitive additional vocational training programmes. This could introduce young employable persons to the labour market as the main producers of common (regional) income. The ideas and conclusions are based on international advanced practices and national educational strategies of designing a model of a new educational ecosystem.

This research shows how port authorities in a triple helix context can contribute to strategic innovation with reduction of Levelized Cost of Energy in nearshore wind park ecosystems. The empirical qualitative case study was conducted from September 2017 to June 2018 with a port and a nearshore wind park owner and a logistic business actor operating on land and one operating at sea. Individual interviews and three joint network meetings provided data for the research. The findings reveal that port authorities in triple helix contexts can contribute to strategic innovation through use of the cross-disciplinary trinity of ‘organization’, ‘business model innovation’ and ‘financial cash flow’ to address value creation on project ecosystem level. The findings are summarized in a model for overview on the shift in interest and the basic understanding of flow. It is shown that the triple helix discussions provide a meaningful frame to achieve strategic innovation for competitive advantage of renewable wind energy ecosystem.Keywordsstrategic innovation – ecosystems – renewable energy – offshore wind parks

There is a growing interest in the application of ecological models to evaluate past, present, and future direct and indirect effects from various stressors including nutrients, organic wastes, flow, temperature etc. in aquatic ecosystems. For this study, AQUATOX simulation was established, calibrated and validated to model the aquatic ecosystem of Yincun Port River with field measured data and historical records between April 2013 and October2014. The results showed the AQUATOX simulation reasonably represented the real situation of Yincun Port. Moreover, sensitivity analysis revealed the value of Phytoplankton Chlorophyll was highly sensitive to nutrient input, temperature and parameters related to temperature limitations. Furthermore, this model was applied as a forecasting tool to analyze the response of Chl. a to nutrient input.

Contamination of marine sediments by organic and/or inorganic compounds represents one of the most critical problems in marine environments. This issue affects not only biodiversity but also ecosystems, with negative impacts on sea water quality. The scientific community and the European Commission have recently discussed marine environment and ecosystem protection and restoration by sustainable green technologies among the main objectives of their scientific programmes. One of the primary goals of sustainable restoration and remediation of contaminated marine sediments is research regarding new biotechnologies employable in the decontamination of marine sediments, to consider sediments as a resource in many fields such as industry. In this context, microorganisms—in particular, fungi and bacteria—play a central and crucial role as the best tools of sustainable and green remediation processes. This review, carried out in the framework of the Interreg IT-FR Maritime GEREMIA Project, collects and shows the bioremediation and mycoremediation studies carried out on marine sediments contaminated with ecotoxic metals and organic pollutants. This work evidences the potentialities and limiting factors of these biotechnologies and outlines the possible future scenarios of the bioremediation of marine sediments, and also highlights the opportunities of an integrated approach that involves fungi and bacteria together.

AbstractIn this paper we consider simplifying a model of the nitrogen cycle in Port Phillip Bay, Victoria, Australia. The approach taken is to aggregate state variables that are linearly related using a projection in state space. The technique involved is a modification of proper orthogonal decomposition and was developed so that a resulting simplified model retains an ecological interpretation. It can be applied automatically, and enables insights into the system to be gained that were not obvious beforehand. In the case of the Port Phillip Bay model, we find that the variables representing water and sand are unaffected by the remaining variables, while only variables on the same trophic level can be grouped together. The validity of the aggregation under several nutrient loads is also discussed.

Despite high competition among big EU ports, such as Rotterdam, Hamburg, or Valencia, acting as Core Ports in the Trans-European Transport Core and Comprehensive Network (TEN-T), this paper addresses the marginalized decision-making capability for environmental and digital transition immanent in the Small and Medium-Sized Ports (SMSPs) ecosystems in the EU. Irrespective of topical research, little is said about SMSPs ecosystem sustainability robustness and how SMSPs can pursue the transformative way. Here, management and strategic port decision levels are rather patchy and disconnected from the operational port performance. SMSPs are bound to limited resources and low cognitive, organizational, or institutional proximity, compared to their bigger counterparts. This situation provides a lot of room for critical demarche, since in the TEN-T Network, there are 225 Comprehensive and only 104 Core Ports, the majority qualifying, thus, as SMSPs. This research aims at reducing this research-to-practice lacuna by improving limited managerial capacity of SMSPs on environmental responsibility and digital efficiency. Using an ecosystem concept and aggregated empirical data in three EU macro-regions—the Baltic Sea Region, the Adriatic-Ionian Sea Region, and the Mediterranean Sea Region, three specific decision-making tools are suggested for managerial applications to facilitate and reinforce transition in SMSPs for environmental responsibility, social equity, and economic efficiency.

The article presents a new contribution to understanding and building novel phenomena of Smart City–Port (SCP) ecosystems and new approaches for the use of new technical and technological findings. The main aim is to elaborate specific strategies SCP ecosystem can secure in the future and an approach for synchronised SCP development for adaption to growing urbanization, mobility and business development, where all stakeholders would take an active role. Based on analysed literature 19 strategies for common smart development of cities and ports are highlighted. The relatively new phenomena of the Internet of Things (IoT) or Internet of Everything (IoE) can simplify their achievement in SCP ecosystem. Moreover, the proposed 3 level approach for technological development of sensing, monitoring and managing data for spatial, transport, environmental and social policy is used on 2 Northern Adriatic cities and ports. The research provides actual analyses of SCP development at Koper (Slovenia) and Rijeka (Croatia), where the development of ports was carried in a completely different way. The article thus proposes a 2 phase approach to the development of SCP and can be used more widely in building a symbiosis of cities and their ports. Firstly, the need to fulfil the strategy from the set of 19 SCP development strategies should be identified and secondly by using a 3 level approach, with existing technological support a SCP environment can be set.

Landscape ecological studies supply valuable data for advanced nature management in the Arctic zone of the Russian Federation. The recently adopted State program for advanced economic development of this zone outlined eight regions for such activities. Our study area Indiga belongs to Nenets advanced economic development region. Its landscapes are presented by rolling and hilly plains at the coast of the Barents Sea. Different tundra types are the most typical vegetation cover, but forest-tundra and even northern taiga are also met. Nowadays Indiga is a small settlement in the mouth of the Indiga river which according to the State program will give rise to a new sea port belonging to the Northern Sea Route infrastructure, railway terminal construction. Dominating nowadays traditional nature management will be completed by transport and residential promoting nature management conflicts emerging from joint exploitation of several ecosystem services by different stakeholders. Such conflicts need elaboration of regulation system. Such regulation is of primary importance for ecosystems with low resilience to technogenic impact which may destroy natural processes of ecosystem services pools reproduction. We present a case study demonstrating the procedure of revealing and mapping of ecosystem services using a landscape map. This is the first step for quoting of ecosystem services exploitation.

Several public seaports and fishing terminals are located in the same port complex but have different fragmented operations such as waste management. It is possible to provide a new initiative to ensure sustainability for all entities in the surrounding port ecosystem through the application of Green Port using the circular economy approach and mixed linear programming model. Therefore, this study aims to explore the collaborative management of waste generated from different port activities such as the operators of the public seaport, fishing terminal, and a city authority in Bali–Indonesia using circular economy principles. It was discovered that the integration model has the potential to generate new energy by recycling waste from all related entities in the production of a few main fishing products such as tuna, sardine, and squid, as well as vessel traffic, facilities, and cargo flow interactions in addition to other port operations.

Ports are a good example of how coastal environments, gathering a set of diverse ecosystems, are subjected to pollution factors coming from human activities both on land and at sea. Among them, trace element as copper represents a major factor. Abundant in port ecosystem, copper is transported by runoff water and results from diverse port features (corrosion of structures, fuel, anti-fouling products, etc.). The variegated scallop Mimachlamys varia is common in the Atlantic port areas and is likely to be directly influenced by copper pollution, due to its sessile and filtering lifestyle. Thus, the aim of the present study is to investigate the disruption of the variegated scallop metabolism, under a short exposure (48 h) to a copper concentration frequently encountered in the waters of the largest marina in Europe (82 μg/L). For this, we chose a non-targeted metabolomic approach using ultra-high performance liquid chromatography coupled to high resolution mass spectrometry (UHPLC-HRMS), offering a high level of sensitivity and allowing the study without a priori of the entire metabolome. We described 28 metabolites clearly modulated by copper. They reflected the action of copper on several biological functions such as osmoregulation, oxidative stress, reproduction and energy metabolism.

During the last decade, growing demand has prevailed for environmental protection and the application of sustainability principles toward the coastal environment. As the coastal zone constitutes one of the first recipients of the impacts of climate change due to the rise in sea level, integrated coastal zone management arises as a significant tool for the study of vulnerable coastal ecosystems. In combination with ICZM, the use of indicators and ecosystem services analysis couples all of the information, leading to an integrated approach and opportunities for a sustainable blue economy in coastal ecosystems. The aim of the present study is to form a protocol for a sustainable blue economy in the coastal zone, which will investigate and define the current capacity and the boundaries of a coastal ecosystem with specific characteristics of industrial activity, cultural heritage, and a protected natural environment. The case study for this research is the Gulf of Elefsis, a special sea basin in the eastern Mediterranean, located a short distance from the Athens metropolitan area. The Gulf of Elefsis is characterized by a developed coastal zone, which includes intense industrial activity, the ancient historical sights of Elefsis, the environmentally protected wetland of lake Koumoundourou, the town of Elefsis, a trade port, and growing shipbuilding activity.

This study investigates the status and anthropogenic pressures on seagrass ecosystem. Urbanization and tourism in the coastal areas of Bintan, Indonesia were increasing in the recent years. They have become new pressures to intertidal ecosystem and habitats, particularly seagrass ecosystem. Seagrass meadows are the important ecosystem and habitats in Bintan region. They provide a wide range of ecosystem services, including for small-scale fisheries and have being Dugongs (Dugong dugon) habitats for food. Currently, the sea grass status is less healthy or damaged with 11 species. The anthropogenic disturbance processes have affected the spatial distribution, percent coverage, biodiversity, and community structure of sea grass. Moreover, several species are hard to find. Directly, sea grass meadows are impacted by introduced coastal development (i.e. settlement area, tourism accommodation, port, etc.), land-based pollution, reclamation, boating traffic, dredging activities and tourism activities. Sea grass conservation area and marine spatial planning based on the land- and seascape connectivity is important for conservation efforts and sustainable management of sea grass.

The Esso Long Island Point facility is situated on the edge of Western Port, an important Ramsar designated wetland for migratory birds in Victoria, Australia. The gas fractionation and crude oil storage facility has operated for over 40 years and has discharged treated wastewater to Western Port for most of these years in accordance with its environmental regulatory licence. The 2003 State Environment Protection Policy for Waters of Western Port is the Victorian Environment Protection Authority’s regulatory framework for licensing wastewater discharges to the wetland, and among other items, requires that discharges must cause no ‘detrimental change in the environmental quality of the receiving waters’ or ‘chronic impacts outside any declared mixing zone’. A major upgrade to the water treatment facility in 2010 included a risk-based marine ecosystem program to monitor key environmental indicators including water quality, jetty pile invertebrate communities and seagrass condition. The program’s longer-term monitoring record has allowed assessment of potential chronic effects on invertebrates and seagrass by comparing temporal changes at monitoring sites over the period from pre-operations (2010) to present (2016) and spatial changes between near-field to far-field sites, kilometres from the discharge point. The program has shown that management of the discharge maintains beneficial uses and environmental objectives at the boundary of the mixing zone, and the marine ecosystem is protected from potentially slower and longer-term adverse effects in the far-field. The program demonstrates that the treated wastewater discharge has had no adverse impact on key environmental indicators in Western Port over the longer-term study period.

In March 2003, a rupture to the Moonie–Brisbane pipeline (MBP) at Lytton (Brisbane) resulted in a spill of 1.9 million litres (7,000 barrels) of crude oil to two hectares of land and 1.5 km of mangrove-lined drainage channels and small creeks near the Port of Brisbane.Due to the swift, coordinated response, no oil reached the Brisbane River and the bulk of the oil spilled was recovered. The response effort included isolation and evacuation of the affected area, containment and recovery of the crude oil and the development and implementation of a clean-up plan (which identified and prioritised response efforts in four primary areas).Following the emergency response a comprehensive program of remediation and monitoring was implemented, with focus on the recovery of the affected waterways and remediation of affected land.This paper describes the methods employed during the emergency response and their effect on the:initial impact on the environment;development and implementation of rehabilitation and remediation options; and,potential for ecosystem recovery.

Abstract The Environmental Impact Assessment (EIA) aims to analyze the environmental viability of projects, but exhibits problems that compromise its quality, such as the fragmented, technocratic and positivist vision. The prediction of environmental impacts can be improved using the ecosystem approach, considering the processes and the ecosystem services affected. The present work applied this approach in the expansion project of the Port of São Sebastião (São Paulo, Brazil), in which the EIA was judicially questioned, based on documental analysis and discussion by specialists. Unlike foreseen in the EIA, the analysis of oceanographic processes showed direct and indirect impacts on ecosystem services and benefits, irreversible and/or of great magnitude. The analysis also allowed an improvement to the comprehension not only on the effects on the environmental components and processes (hydrodynamics, sediment dynamics and biodiversity), but also on human well-being, evidencing the benefits of applying the ecosystem approach in the EIA.

Due to rapid urbanization, increase in coastal population, oil and gas exploration and other array of anthropogenic activities within the Niger Delta region of which Rivers and Bayelsa states are prominent amongst others, the region has been faced with coastal water pollution. There is need therefore, to evaluate the intensity of environmental contamination of the aquatic ecosystem in this region, thus this study was conducted to investigate the heavy metal levels of Clams (Egeria radiata) sold in open markets in Port Harcourt (Rivers State) and Yenagoa (Bayelsa State). Samples were collected from three markets in Port Harcourt (Mile 1, Rumuokoro and Mile 3), and three markets as well in Yenagoa (Opolo, Swali and Tombia) respectively. The samples were collected bi-weekly for 3 months and transported to the laboratory for analysis of heavy metals (Cr, Cd and Pb) levels using standard scientific method of analysis. The analysis was done in triplicates for each sample and data obtained were subjected to statistical analysis using excel spreadsheet and statistical package for social sciences (SPSS) version 21. The results revealed that samples collected from markets in Port Harcourt had higher concentrations of heavy metal than that of Yenagoa, though, the heavy metal levels were below World Health Organisation permissible limits, except for Cadmium (Cd) that ranged from 0.54±0.002 to 0.78±0.00 mg/kg in samples collected from Port Harcourt, against 0.5 mg/kg recommended by WHO. This could be attributed to oil and gas exploration, and discharges of industrial and domestic wastes bearing cadmium, and poses serious health risks. Therefore, routine monitoring and assessment of the aquatic ecosystem will be vital to forestall further contamination.

Floating wetland islands (FWI) are considered nature-based solutions with great potential to promote several ecosystem services, such as biodiversity and water quality enhancement through phytoremediation processes. To our knowledge, the present work is the first to scientifically document the in-situ establishment of an FWI in a seawater port marina. The establishment and performance of a cork floating platform with a polyculture (Sarcocornia perennis, Juncus maritimus, Phragmites australis, Halimione portulacoides, Spartina maritima, Limonium vulgare) was evaluated. The diversity of organisms present in the FWI was undertaken based on the macrofauna assessment, taking into consideration marine water characterization, with a focus on hydrocarbons. Microbial communities were assessed based on metabarcoding approach to study 16S rRNA gene from environmental DNA retrieved from biofilm (from the planting media), marine biofouling (from the submerged platform) and surface marina water. S. perennis was the species with the highest survival rate and growth. The structure of the microbial community showed clear differences between those established in the FWI and those in the surrounding water, showing the presence of some bacterial groups that can be relevant for bioremediation processes (e.g., Saprospiraceae family). Concerning the macrofauna analysis, Mytilus sp. was the predominant taxa. To be of relevance, total petroleum hydrocarbons were detected at the marina up to ca. 6 mg/L. This study gives new insights into broadening FWI application to the saline environments of port marinas and to supporting a management strategy to promote several ecosystem services such biodiversity, species habitat, water quality enhancement and added aesthetic value to the marina landscape.

In this study, the ecosystem service function value of Lingang wetland park was calculated,such as hydrological regulation,water conservation and purification, biological habitat, erosion control, carbon sequestration and oxygen release port,with the market value method, carbon tax and forestation cost method, shadow engineering method, replacement cost method ,ecological value method and other methods. The results showed that the total ecosystem service function value of this wetland park is ¥1.03×108•a-1. The species habitat, carbon sequestration and oxygen release and hydrological adjusting function value is larger, which is 40.3%, 38.3% and 13.0% of the total value, so they are the main core function value of the Park. Therefore, the scientific and rational planning should be carried out in the development of the wetland park, avoiding influencing the ecosystem service function of this park.

This paper overviews the ecosystem model developed for the Port Phillip Bay Environmental Study. The model simulates the cycling of N, P and Si in the water-column, epibenthos and sediments, and is driven by a physical transport model. The integrated model is forced by exchanges with Bass Strait and by nutrient inputs from the Western Treatment Plant, rivers, and the atmosphere. The model has been calibrated and tested by using data from process studies, flux measurements and spatial surveys at a range of scales. It provides a picture of nitrogen cycling through the water and sediments on bay-wide annual scales, which emphasizes the role of denitrification. It also reproduces well the observed spatial and temporal variation under varying nutrient load regimes, and provides insights into the factors controlling regional phytoplankton blooms, including the interaction of nitrogen and silica in the western bay. The model is used to investigate the bay’s responses to changed nutrient loads, changes in sediment biogeochemistry, and marine pest invasion. The bay’s assimilative capacity for nitrogen is largely controlled by its sediment denitrification capacity. If nitrogen loads approach the limits of this capacity, a rapid onset of eutrophication is predicted.

Shipping is facing huge pressure problems in this 21st century such as climate change and environmental pollution and the depletion of energy resources. Seaports are an important component of the shipping industry architecture. Although there is no common solution, seaports around the globe face the same challenge. Challenges raised include difficulties in integrating new technology into automation, traffic congestion, harmonizing residential communities around the port, quantifying and reducing CO2 emissions as well as planning for the energy transition. In addition, improving the adaptability of the port infrastructure in the context of increased pressure from market demand, labor shortage, and escalating prices should be considered. In that context, a smart port was born as a necessity. However, the understanding of smart ports is very limited. This review examines the recently published smart port literature to clarify the common concepts of smart ports and their development progress on the way to building a sustainable seaport ecosystem. Although smart port metrics and key port performance metrics are organized around four key performance areas including operations, environment, energy, and safety. However, a comprehensive review of all four key areas is very broad and difficult to cover in a review article. Therefore, this work focuses on analyzing and discussing the approaches and applications of the technology in smart port energy management systems. Our research has shown that different smart port founding perspectives play a decisive role in technology approaches to building a port energy management system including optimizing algorithms for energy consumption, balancing demand and energy production, and comprehensively integrating renewable energy. New findings in this study contribute to the elucidation of smart port concepts based on improving energy use and management efficiency with innovative technologies in the context of sustainable development of the shipping industry.

Trends in logistics and more broadly across technology and energy are resulting in changes to the traditional business models and functions of ports. Because the port ecosystem is going to be considerably different in the following two decades, decision-makers need to have a “port vision” for the year 2040 to prioritize investments and build a strategic plan. This paper seeks to analyze the current trends that have an impact on ports and the subsequent changes in their roles. The impacts are identified by means of Delphi methodology, which is applied to the Port Community of Barcelona. The results of this paper will contribute to the vision of ports of the future by identifying the main trends that will have an impact on ports in the long term (2040). The research has been able to identify the key drivers that will transform ports: green measures to decarbonize maritime transport and supply chains; 3D printing hubs for production or customization on site and available on demand in or next to port areas; new physical and digital infrastructures for automated and connected vehicles and port terminals; and finally, full digitalization to offer new services (track and trace, call optimization, etc.) as well as an optimized supply chain oriented to e-commerce’s exigent and flexible final clients.

AbstractOver the last decade, the Antarctic continent has been the object of intensive scientific programmes. However, the emphasis of these studies rarely focuses on the Antarctic as a source of potential elements such as mercury. The release of mercury to the environment is known to occur at Deception Island, associated with volcanic activity. In this study, a 3D hydrodynamic model was used to assess the role of water circulation on the dispersion of released mercury. Sea level variation and tidal circulation data were obtained. Residence time was calculated using two different approaches. Internal tide generation in summer and winter were recognized and the barotropic tidal components obtained. Lagrangian tracers were used to depict particle circulation (simulating particulate mercury) in a three month summer simulation for barotropic and baroclinic conditions. The results show that particles accumulate in the northern and western parts of the bay. It is acknowledged that the results of the 3D model are associated with a non-negligible uncertainty, which can only be reduced with an ongoing commitment to monitoring. The findings of this study indicate that mercury accumulation is occurring in Port Foster (Deception Island), which is a potential threat to the local ecosystem.

The purpose of the study was to identify some practical approaches to help developing nations for leasing their carbon footprint that is left behind as a result of operations at ports and terminals. In this sense, the Bangladeshi seaport of Chattogram serves as a case study that is monitored and analyzed. Investigation on port and terminal procedures and CO2 emissions is the focus of this study. Conversations with port stakeholders are the main source of data. When it comes to secondary data, it's drawn primarily from past studies and newspaper articles. Approximately 65.8% of the total carbon emissions at Chattogram's port and terminal are attributed to ships anchoring at the port. Other options include port boats with 19%, freight handling equipment with 10% and vehicles with 4.5%. In order to reduce these emissions, the port of Chattogram has determined that cold ironing is the best alternative, and contemporary cargo handling equipment is both cheaper and uses less energy. In order to ensure that port and terminal activities have a minimal impact on the surrounding ecosystem, it is imperative to update outdated pieces of equipment and extend existing terminal facilities. Nevertheless, utilizing renewable fuels (30% biofuels with currently used diesel) can be an effective solution for lowering the carbon footprint of other types of machinery such as forklifts and harbor craft. Furthermore, developing countries may join and coordinate with the LEARN (Logistics Emission Account and Reduction Network) project to enhance and globalize their efforts to reduce their carbon footprint through emission measurements, reporting, and verification (MRV).

For the first time in thirty years, baseline comprehensive studies plankton and zoobenthos of the Sukhum Bay were conducted and an assessment of its current environmental status was given. The summer phytoplankton abundance of the port of Sukhum was represented mainly by coccolithophorids Emiliania huxleyi and diatoms algae, among the latter, the common species in polluted or eutrophic brackish waters were recorded. The presence of euglenic algae and cyanobacteria indicates a higher nutrient status, pollution and desalination of the sea area. The alien species Peridinium quinquecorne Abé (Dinophyceae) was recorded in the Abkhazian coastal waters for the first time. Totally, 7 species of tintinnids belonging to 3 genera Favella, Tintinnopsis, Eutintinnus were established from the Sukhum Bay. Among them, the non-indigenous species Eutintinnus tubulosus and E. apertus were noticed. Tintinnid ciliates accounted for ca. 5% of total ciliates abundance. The values of the abundance of aloricated ciliates were comparable to the values obtained from offshore of bays and ports of the northeastern Black Sea. As the pressure of predators is reduced the well-pronounced peaks of holo- and meroplankton biomass were recorded in the last summer – early autumn. A significant part of total holoplankton biomass – 66.5 % (up to 1.1 g/m3) was composed of cladocerans Penilia avirostris. The meroplankton was dominated by larvae of bivalve mollusks Mytilaster lineatus, polychaetes Polydora cornuta and cirripede barnacle Amphibalanus improvisus. The number of meroplankton in the open Sukhum port was 10–15 times lower above than a level of values obtained for ports and bays of the northeastern Black Sea. Among ichthyoplankton, the dominant species were Mullus barbatus ponticus, Diplodus annularis, Trachurus mediterraneus, Engraulis encrasicholus and Sciena umbra. Mean abundance of ichthyoplankton in vertical catches was 5–10 times lower than in offshore of Anapa and Gelendzhik of the northeastern Black Sea. And the proportion of dead eggs was 2 – 3 times higher than areas of these resort cities. The composition of macrozoobenthos was drastically depleted and resembled that of the polluted port complexes of the northeastern Black Sea. Heteromastus association dominated in mud bottom sediments. Among spionid polychaetes, the worst invaders Streblospio gynobranchiata and Polydora cornuta have been recorded in soft bottom communities. Depletion of benthic communities, loss from the structure of the trophic web of the macrophyte community and appearance of cyanobacteria and a new alien species in the planktonic and benthic communities leads inevitably to imbalance of the structure of the Sukhum port ecosystem.

Coastal erosion is a major global problem and is most acutely felt along developed coastal areas where coastal communities and infrastructures are threatened by storm surge flooding. This situation gets compounded to a bigger challenge around most of delta plains which are rapidly subsiding. The degree and magnitude of challenges associated with erosion and submergence along muddy deltaic coasts is intricately related to population density. It is estimated that about 500 million people in the world live on river deltas (Syvitski et al., 2009). Coastal populations and their associated industries/economies (oil & gas, fisheries, port and commerce etc.) are thus threatened by rapid degradation of the deltaic landscapes. This situation is further complicated by sea level rise and high-energy events such as hurricanes (cyclones, typhoons).
