Full textAbstract:
The article is devoted to the review of domestic and foreign studies of methods and models that characterize the sustainable development of territories. An overview of the main trends in the development of the concept of sustainable development is given. The necessity of instrumental assessment, retrospective analysis and forecasting of the ongoing processes is substantiated by the formation of appropriate indicators and quantitative indicators. A comprehensive risk assessment strategy based on the matrix approach mechanism includes an assessment of the main indicator classes, each of which consists of a set of indicators (indicators). The main indicator classes include economic indicators, indicators of environmental quality, indicators characterizing the health of the population and demographic processes. Based on the above indicators, a comprehensive strategy for assessing the analysis of risk indices in the study area can be implemented. Modern methods for assessing the sustainability of Russian regions are consistent with foreign developments since the very concept of sustainable development is universal for all countries. It should be noted that most of the studies are of a narrow-sectoral nature, the monitoring criteria, and approaches to modeling the sustainable development of the territory are largely unclear, which indicates an insufficiently deep development of the problem as a whole and the need for its conceptual substantiation. Research trends on this topic mainly consist in the search for the most adequate criteria and parameters by which it is possible to assess the ecological state of the coastal zone, the peculiarities of the economic development of the study area, medical and social processes of the coastal zone.

Integrated Coastal Management (ICM) initiatives spread all over the world to cope with declining conditions and intensifying user conflicts to achieve sustainable development of coastal resources and environment. A set of indicators with regard to sustainable development and governance aspects were developed in Xiamen to monitor the State of Coasts (SOC) under ICM implementation. In developing the evaluation indicators for Xiamen, a number of lessons were learned related to data compilation, indicator development, public participation and scaling up. The experience of Xiamen was believed to contribute to develop evaluation indicators for ICM in China.

Full textAbstract:
Monitoring on coastal erosion problems along the São Paulo shoreline have been carrying out by the author since mid the 80’s, including almost 87% of the whole 430 km length of sandy beaches. Eleven types of indicators of coastal erosional processes have been recognized, which have been attributed to seventeen causes, among them ten correspond to natural mechanisms and seven are due to anthropogenic interference. In this paper is presented rates of shoreline retreat based on the Bruun Rule application for six of the most threatened beaches, for a period as long as 56 years. Risk assessment is also estimated for these six beaches based on two criteria: (i) the total number (sum) of types of coastal erosion indicators found along the shoreline (frequency among the 11 types) and (ii) general spatial distribution (percentage of surface area) of coastal erosion indicators along the shoreline. Causes and effects of the coastal erosional processes are discussed for these six beaches. Results reveal high rates of shoreline retreat, even in non-urbanized areas, as well demonstrate that the six beaches are at very-high risk. Moreover, they indicate that natural mechanisms are very important as cause of coastal erosional processes in São Paulo, sometimes most them the human-induced causes. These studies have widely been supporting the State Plan for Coastal Zone Management, in order to create special rules for occupation and some activities along the shoreline, including engineering works, building and sand beach exploration. Besides, results are being recorded in a geoenvironmental information system for the Coastal Zone of the State of São Paulo (Project SIIGAL), which is in phases of implantation.

In order to get a scientific assessment of the coastal ecosystem health in Qingdao, a study on ecosystem health assessment of Qingdao coastal zone during 1998-2009 based on press-state-response (PSR) model contained a series of indicators was conducted. In this paper, the integrated ecosystem health index was calculated through weight values multiplied the standardization values of the indicators. The results indicated that the IEHI in the coastal zone of Qingdao fluctuated by a large margin during 1998-2009, when the IEHI range from 0.35 to 0.84, and the ecosystem was in the states of unhealthy and subhealthy in most of the time interval. The urban expansion and the three wastes were the dominating pressure factors which effected the coastal ecosystem health. The atmosphere and inshore environment took a turn for the worse, while the cultivated land resource exhausted almost. In order to improve the coastal ecosystem health, it was quite necessary to increase the forest coverage rate, tertiary industry proportion and investment in environmental protection.

Full textAbstract:
Implementation of Trophic Status Index in Brackish Water Quality Assessment of Baltic Coastal Waters The assessment of the trophic state of marine coastal waters is one of the leading initiatives declared in the European Water Framework Directive (WFD). The Baltic Sea is a semi-enclosed ecosystem which consists of subregions with wide salinity and seasonality gradients. Anthropogenic impact results in eutrophication processes on different scales. Efficient eutrophication control and environmental management in the Baltic Sea, according to WFD, requires a prerequisite of common and sensitive indicators for the European coastal waters including the Baltic Sea. In this article the Trophic Status Index TRIX, recently succcesfully implemented in Mediterranean and Northern European sea coastal waters as a holistic approach indicator, was implemented for the Gulf of Rīga and Latvian Baltic Sea coastal water quality assessment between 1999 and 2005.

Full textAbstract:
The accelerated socioeconomic development has placed the coastal ecosystems under stress, which influences the sustainable development of coastal areas. Marine eco-environmental carrying capacity assessment (MECCA) can provide a scientific basis for coordinating coastal socioeconomic development and eco-environmental protection, ensuring a more effective marine ecosystem-based management approach toward sustainability. However, accurate assessment methods are still in the exploratory stage, as there has been a lack of systematic research and applications combining integrated MECCA with a unified method to underpin coastal management processes. In light of this issue, this study applied the marine eco-environmental carrying capacity in coastal waters (MECCCW) conceptual framework to support the establishment of an assessment indicator system for MECCA and used the regularization method and entropy method to determine weights. This study also applied the simplified state space model to comprehensively evaluate and analyze the marine eco-environmental carrying capacity (MECC) of coastal areas. Focusing on the coastal area of Sanya Bay, southern China, as the study area, we assessed the MECC for the period from 2015 to 2020. The state of the MECC was divided into three grades: load capacity, full-load capacity, and overload capacity. The results showed that (1) the MECCA indicator system in Sanya Bay included a total of three criteria and eight assessment indicators and (2) the weights of the environmental carrying capacity (ECC) and human activities (HA) were both relatively higher than that of ecological resilience (ER). The latter result indicates that either ECC or HA could play a more predominant role in the changes of the MECC state in Sanya Bay. The results also indicated that (3) for each criterion, ECC, ER, and HA were at load capacity from 2015 to 2020. In this instance, ECC and HA presented similar change trends in relation to the MECC state of Sanya Bay. Finally, (4) the overall Sanya Bay’s MECC was also at load capacity and weakened, fluctuating between 2015 and 2020. These findings indicate that the coastal area of Sanya Bay is capable of sustainable development, but that there is a need for further eco-environmental improvement. The results of this study can serve as a reference when decisions have to be made about coastal management from an environmental and ecological perspective. Furthermore, this method may provide a feasible approach for integrated MECCA in other coastal areas.

Full textAbstract:
Abstract Geoindicators are means adopted for the measurement of geological processes and phenomena that occur at or near the Earth's surface and vary significantly over periods of 100 years or less. These tools have focused on assessing geological impacts and risks over the last three decades. However, the use of geoindicators is not widely known and has not been as greatly exploited as have most environmental indicators. The objective of this study is to contribute to the diffusion of information about and the application of geoindicators. We have defined, in terms of geoindicators, parameters and aspects of coastal environments that are commonly studied or monitored. The geoindicators proposed were designed for assessing coastal physical vulnerability in the case of the coastal beaches of Rio Grande do Sul, Brazil. Four geoindicators were defined and tested: the height and morpho-ecological state of the foredunes, shoreline position, and washout concentrations. An additional sócio-environmental indicator was included, sanitary quality. These indicators were brought together to constitute a Physical Vulnerability Index that represented seven locations along the coastline assessed. In addition, the indicators and Index values were used to generate a cartographic map that could be understood by the public and used by decision makers.

Full textAbstract:
The indicator properties of zooplankton assemblages in a coastal lagoon were evaluated, by means of canonical correspondence analysis, along environmental gradients of trophic state and marine influence caused by anthropogenic impact. Changes in zooplankton species composition were significant indicators of environmental heterogeneity patterns. Species diversity was insensitive to eutrophication but decreased with increasing marine influence. The rotifer species Brachionus plicatilis and Synchaeta bicornis as well as cirriped nauplii were good indicators of mesohaline conditions. The rotifer species Asplanchna brightwelli, Brachionus angularis, Brachionus falcatus, Filinia terminalis, and Polyarthra remata were good indicators of eutrophic conditions. The other species investigated were good indicators of oligohaline and mesotrophic conditions. The rotifer genus Brachionus proved to be a better indicator organism for these environmental gradients than the entire zooplankton assemblage. Hence, this taxon can be considered a target taxon for more intensive monitoring and conservation planning. The method used here to assess the indicator properties of species assemblages and to select target taxa can be widely applied in any aquatic ecosystems to any group of organisms, spatial and temporal scales, and environmental gradients.

This article analyzes the problem of the state of the water bodies in Ishim by anthropogenic pressures. The study shows that the water reservoirs are negatively influenced by the economic activities of the population. The author defines their main directions: industrial wastewater discharge to the city water bodies, construction and operation of engineering constructions, activity in the private sector. To assess the state of the water bodies the author uses the results of the visual assessment of the state of the riverbeds and their coastal zone, the organoleptic water indicators (turbidity, color and smell), the analysis of the hydrobiological studies (determination of the degree of saprobity of the water bodies as indicators ciliated infusoria). The study showed the satisfactory condition of all the water reservoirs and the non-critical impact. As the enterprises for light manufacturing and food industries in Ishim are not sources of chemical, organic and other pollution the visual assessment didn't reveal significant deformations of the riverbeds and any changes in the coastal zone. The impact of the private sector is local and not the significant cause of organic pollution.

Adaptive management is a key component of a forest project being implemented across all of Weyerhaeuser's coastal forest tenures. This project uses two main tools to accomplish the British Columbia (BC) Coastal Group's ecological and socio-economic goals: variable retention (VR) harvesting and broad zoning of the land base. The adaptive management program was designed to examine the effectiveness of retention systems and zoning in maintaining those forest attributes necessary to sustain biological richness and essential ecosystem functions, such as nutrient transfer, energy flow, decomposition, and dispersal of seeds, spores, and animals. The program is grounded on three biological indicators evaluated in both operational and experimental contexts: 1) representation of habitat types in a relatively unmanaged state to ensure that little-known species are retained; 2) structure of stands and landscapes to ensure that key elements are present through time; and 3) indicator organisms to track whether retaining structures and patterns, while addressing representation, will maintain species and populations whose life needs are well understood. Representation of ecosystems in unmanaged conditions has been examined. Habitat structure is being assessed in VR blocks and in unmanaged blocks. Studies on several organisms (breeding birds, owls, gastropods, amphibians, bryophytes, lichen, squirrels, mycorrhizae, and carabid beetles) have been underway for various lengths of time. These studies collected baseline information to begin comparisons of the effectiveness of the various types of VR for maintaining biological richness. The current focus in the adaptive management program is refining the lists of specific elements to monitor and beginning to create tools to help extrapolate relationships and findings over large areas and long time frames, with the expectation of operational implementation in 2003. The first two years of pilot work are also being used to examine how the results will link to management practices to strengthen areas that most need improvement. This paper describes three indicators used in Weyerhaeuser's adaptive management program. Key words: adaptive management, variable retention harvesting, indicators for monitoring forests

The Black Sea is one of the main recreational facilities in Russia subject to a high annual anthropogenic stress. Anthropogenic activity led to high coastal sea waters pollution, eutrophy, and endangered the sea’s self-purification capabilities. The total quarantine introduced on the Black Sea coast of the Krasnodar territory associated with the new coronavirus infection COVID-19 pandemic led to a decrease in anthropogenic pressure on coastal ecosystems and provided a unique opportunity to trace the dynamics of the most important hydrochemical indicators of coastal waters in the Tuapse district. The study aimed to characterize the impact of quarantine measures against the coronavirus on the state of coastal waters in the eastern part of the Russian Black Sea. For this, we identified and characterized the hydrochemical indicators and determined the effect of quarantine measures on their dynamics. The study used the standardized methods. The results obtained showed that a decrease in the recreational stress led to a proportional decrease in the pollutants supply to coastal sea waters; with the recreational stress resumption the concentrations of mobile pollutants tended to increase; a proportional relationship was established between biochemical oxygen demand (BOD5 ) and the ammonium nitrogen (NH4+) concentration; the nitrates’ (NO3–) concentration, in the seawater did not depend on the recreational stress degree. In particular, a proportional increase in NH4+ concentration and BOD5 in seawater was detected: in the third quarter of 2019 the concentration of NH4+ and BOD5 amounted to 3.0 mg/dm3 and 8.5 mg/dm3 , and 3.8 mg/dm3 and 7.5 mg/dm3 in the fourth quarter, respectively; in the 2020 samples, a decrease in the NH4+ concentration to 0.8 mg/dm3 in the third and to 1.2 mg/dm3 in the fourth quarter led to a proportional decrease in BOD5 4.5 mg/dm3 and 3.9 mg/dm3 , respectively. Thus, it was shown that the quarantine measures were shown to have a positive effect on the processes of self-purification of coastal sea waters in recreational zones.

Coastal ecosystems are attractive sites for tourism. In the central Pacific coast of Mexico in the La Boquita coastal system (LBCS), consisting of a beach and a coastal lagoon, the Driver-Pressure-State-Impact-Response (DPSIR) model was implemented for the spatial and temporal analysis of socio environmental indicators, aiming to gather information for decision-making and implementation of management strategies. The spatial occupation (umbrellas and tables) of the beach showed a 50–200% increase during the Easter season relative to the low season, while the area containing restaurants (called “ramadas”) increased by 396% in 15 years, representing pressure on land use for tourism purposes. The density of beach users ranged from moderate to high (<10 m2/user) during the holiday seasons in the tourism area. The Trophic index (TRIX), used as an indicator of trophic status, revealed mesotrophic-to-eutrophic conditions in lagoon water due to the limited water exchange with the adjacent ocean and to DIN and DIP inputs from adjacent tourist areas. The analysis of the environmental legislation showed that law enforcement in the LBCS is poor or nil, with most environmental regulations either ignored or having inadequate enforcement monitoring. This has led to the current state of socio environmental disruption.

This study evaluated the profitability analysis of small-scale fishing along coastal areas of Ondo State, Nigeria. Structured questionnaire was used to collect data from 400 small-scale fishermen which were selected via multi-stage sampling procedure. Data collected was analyzed using descriptive statistics and profitability indicators. Results revealed that mean age of respondents was 39 years, among the fixed assets for fishing, outboard engine has the largest percentage cost (88.32%) while among variable assets, fuel has the largest percentage cost (67.16%). Profitability indicators such as Benefit Cost Ratio (BCR) 1.29, Gross margin ₦1,261,476.60k/fisherman/year, Return on Investment (ROI) 0.29, Net Profit Margin (NPM) 0.23 and Gross Revenue Ratio (GRR) 0.77 were used to estimate the profitability of small-scale fishing. The findings further revealed that fishing boat (1.284), outboard engine (0.352), fishing nets (1.342) and fuel (0.193) were positively and statistically significant at p<0.05 level with fish output level while accessories (floats, sinks and hooks) (0.142) was positively and statistically significant at p<0.1 with fish output level. The R2 value was 72.1% showing that the independent variable was well explained by the exogenous variables. Problems encountered by small-scale fishermen include inadequate infrastructural facilities, poor road networking system and inadequate credit facilities. Based on the findings, it was recommended that small-scale fishermen should organize themselves into cooperatives in order to increase their credit accessibility. Likewise, government should embark on construction of good road network in order to ease transportation of fish harvested to the neighboring towns.

By using the mean directions of the wave-fronts approaching the Brazilian northeastern coastal stretch comprised between the localities of Real river (Sergipe State) and Galinhos (Rio Grande do Norte State) - coincident with those of the main winds occurring in the area - and their periods, we have defined a wave climate model based on the construction of refraction diagrams. The resulting model of sediment transport, as obtained by numerical modelling from the refraction diagrams, taking into consideration the angle of approach and waves heights along the 10-m isobath, was capable of reproducing the patterns of sediment dispersion provided by geomorphic indicators of the longshore drift. All this coastal region, approximately 900 km in length, is characterized by a significant divergence zone in the direction of net longshore drift of sediments, the potential intensity of which increases considerably in value, in almost its entire length, continuously toward downdrift, which might explain the greater or lesser long term susceptibility to erosion, during the Quaternary, along the coastal stretch studied.

Full textAbstract:
In accordance with the water management zoning of the territory of Ukraine, the Poltva river basin belongs to the Vistula river basin region. The evaluation methodology of the channel and floodplain river complex state was proposed by Himko R. V. (2005). According to this methodology, the parameters (23 indicators), characterizing river state by points scale (5 quality classes), were defined. The research included three steps. During the preparatory stage cartographic materials were investigated and the coastal protection zones were highlighted. The fieldwork stage included: visual assessment of water quality and of the state of channels; identification of sources of pollution and clogging of waters and coastal areas; study of features of anthropogenic load within floodplains. In the third stage, generalization and evaluation works were carried out. Wastewater discharges from enterprises and coastal settlements affect the water quality of the study area. Lviv has the greatest economic impact on the Poltva river due to its channelling within the city and due to large volumes of wastewater discharges (121.4 million m3 in 2017). The water quality of the Poltva River tributaries depends on sewage discharges from small industrial and public utilities, as well as on unauthorized sewage discharges in villages. Significant parts of the river channels are regulated. Drainage systems, that occupy much of the study area, as well as ponds and small reservoirs, directly affect on the hydrological regime of the rivers. The level of land-use of coastal territories is characterized by their urbanization level and their level of plowing. The urbanization of the upper reaches of the Poltva river valley is a determining factor that has influenced the sanitary status of its channel. Outside the Lviv city, many coastal areas (within the coastal protection zones) are plowed. Overgrowing of waters and obstruction of channels by water and coastal plant remains lead to a significant deterioration of sanitary conditions of the rivers, hence to secondary contamination of its waters. Geoecological state of the Poltva river channel and floodplain complex was designated as «unsatisfactory» (4th grade from 5 classes), of Yarychivka and Gologirka river complexes – as «satisfactory» (3rd grade), of other rivers – as «rather good» (2nd grade). The rivers of the Poltva watershed are under significant economic influence. To improve the geoecological state of river channels and floodplains, a complex of water protection measures is required: reduction of insufficiently treated wastewater discharges of Lviv city; cleaning of watercourses; monitoring of compliance with water protection rules etc.

Abstract Shannon, L. J., Coll, M., Yemane, D., Jouffre, D., Neira, S., Bertrand, A., Diaz, E., and Shin, Y-J. 2010. Comparing data-based indicators across upwelling and comparable systems for communicating ecosystem states and trends. – ICES Journal of Marine Science, 67: 807–832. A suite of ecological indicators was selected for communicating, in a comparable way, how fishing affects the state of several upwelling ecosystems and others in which small pelagic fish play key ecological roles. Detailed background and understanding of system-specific processes and changes is needed for proper interpretation of results. In particular, environmental forcing is important in driving dynamics in upwelling systems; fishing impacts cannot be understood without understanding the corresponding dynamics of the environment. The Saharan Coastal (Morocco) and southern Benguela, both having experienced upsurges in low-trophic-level species, differed from other ecosystems when considering indicator trends. The ecosystem off Portugal emerged as showing reduced signs of fishing impacts in recent years, although the change may also be reflecting climate change favouring recruitment and abundance of demersal stocks. The indicator suite confirmed general understanding that the Mediterranean ecosystems have been notably degraded for several decades. Results and conclusions from this descriptive synthesis are compared with other comparisons of more complex, model-derived indicators. Even in upwelling and comparable systems, the simple data-based indicators are useful in synthesizing information on the status of an ecosystem, in particular on the ecosystem effects of fishing, to provide an ecological diagnosis at the ecosystem level, to be used in decision-making. Indicators of recent ecosystem state and trends over time are needed to assess the effects of fishing, but more indicators measuring biodiversity attributes and environmental change would complement the suite, providing fuller assessment of the status of upwelling and comparable ecosystems.

Coastal wetlands represent particularly valuable natural resources, characterized by the interaction between their geomorphological and biological components. Their adaptation to the changing conditions depends on the rate and extent of spatial and temporal processes and their response is still not fully understood. This work aims at detecting and improving the understanding of the transition dynamics on eco-geomorphological structures in a coastal wetland ecosystem. The approach could support sustainable habitat management improving the detection and optimizing the offer of Earth Observation (EO) products for coastal system monitoring. Such course of action will strengthen evidence-based policy making, surface biophysical data sovereignty and the Space Data downstream sector through remote sensing techniques thanks to the capability of investigating larger scale and short-to-long-term dynamics. The selected case study is the Lido basin (Venice Lagoon, Italy). Our methodology offers a support in the framework of nature-based solutions, allowing the identification of ecosystem-level indicators of the surface biophysical properties influencing stability and evolution of intertidal flats on which a conceptual model is implemented. Landsat satellite imagery is used to delineate the spatial and temporal variability of the main vegetation and sediment typologies in 1990–2011. Within this period, specific anthropic activities were carried out for morphological restoration and flood protection interventions. Specifically, the lower saltmarsh shows its more fragmented part in the Baccan islet, a residual sandy spit in front of the Lido inlet. The area covered by Sarcocornia-Limonium, that triggers sediment deposition, has fluctuated yearly, from a minimum coverage of 13% to a maximum of 50%. The second decade (2001–2009) is identified as the period with major changes of halophytic and Algae-Biofilm cover typologies distribution. The power law and related thresholds, representing the patch size frequency distribution, is an indicator of the ecosystem state transition dynamics. The approach, based on multi-temporal and spatial EO analysis, is scalable elsewhere, from regional to local-to-global scale, considering the variability of climate data and anthropogenic activities. The present research also supports sustainable habitat management, improving the detection, and optimizing the offer of EO products for coastal system monitoring.

The eastern region of India, including the coastal state of Odisha, is a moderately seismic-prone area under seismic zones II and III. However, no major studies have been conducted on earthquake probability (EPA) and hazard assessment (EHA) in Odisha. This paper had two main objectives: (1) to assess the susceptibility of seismic wave amplification (SSA) and (2) to estimate EPA in Odisha. In total, 12 indicators were employed to assess the SSA and EPA. Firstly, using the historical earthquake catalog, the peak ground acceleration (PGA) and intensity variation was observed for the Indian subcontinent. We identified high amplitude and frequency locations for estimated PGA and the periodograms were plotted. Secondly, several indicators such as slope, elevation, curvature, and amplification values of rocks were used to generate SSA using predefined weights of layers. Thirdly, 10 indicators were implemented in a developed recurrent neural network (RNN) model to create an earthquake probability map (EPM). According to the results, recent to quaternary unconsolidated sedimentary rocks and alluvial deposits have great potential to amplify earthquake intensity and consequently lead to acute ground motion. High intensity was observed in coastal and central parts of the state. Complicated morphometric structures along with high intensity variation could be other parameters that influence deposits in the Mahanadi River and its delta with high potential. The RNN model was employed to create a probability map (EPM) for the state. Results show that the Mahanadi basin has dominant structural control on earthquakes that could be found in the western parts of the state. Major faults were pointed towards a direction of WNW–ESE, NE–SW, and NNW–SSE, which may lead to isoseismic patterns. Results also show that the western part is highly probable for events while the eastern coastal part is highly susceptible to seismic amplification. The RNN model achieved an accuracy of 0.94, precision (0.94), recall (0.97), F1 score (0.96), critical success index (CSI) (0.92), and a Fowlkes–Mallows index (FM) (0.95).

Coastal zones are integral natural and socio-economic territorial-water system, combined by a complex structure of interactions. Coastal geosystems are unique, rich in natural resources, which determines their attractiveness for industrial and residential, recreational, transport and other activities, but also makes them environmentally vulnerable. Sustainable development of the coastal zone is determined by the economic, social, and environmental components. The research area of interest is the coastal zone of the Sea of Azov (Rostov Region). The subject of the study is the state of medical and environmental safety of the territories. The purpose of the study is the analysis of medical-ecological and socio-demographic factors as the basis for sustainable development of the coastal zone of the Sea of Azov. A systematic approach has been implemented to assess the sustainable development of the coastal zone and to develop methods for analyzing and integrating heterogeneous data. Changes in the coastal zone were evaluated based on a comparative analysis of multizone satellite imagery with ground-based studies, data from thematic maps. For the analysis of medical and environmental safety, an author’s technique was used, combining traditional methods and geoinformation technologies based on ArcGis Desktop*. The environmental quality indicator was considered in terms of the impact on human health. Assessment of demographic security was carried out based on the coefficient of demographic well-being / prosperity of the territory. The incidence rate of malignant neoplasms was considered as a highly informative and socially significant indicator of the health status of the population. For analysis, we used the SSC RAS database for 2006-2016. A comprehensive analysis of the development factors of the coastal zone of the Sea of Azov showed significant problems in the studied region. The most attractive areas of the coastal zone of the Sea of Azov from the point of view of infrastructure development are at the same time subject to changes due to dangerous natural phenomena. Analysis of demographic indicators confirmed the presence of adverse demographic processes.

Sea resort areas are currently one of the most successful developing regions. At the same time, the ecological condition of such regions is important, especially those that specialize in the provision of recreational and tourist services. The quality of coastal water resources played an important role in the sustainable development of those coastal tourist areas. Analysis of physical factors of water exchange was carried out and assessment of water resources quality of the coastal zone of the sea was made, including in closed and semi-enclosed water areas. It has been shown that water exchange is the most important factor in the management of the quality of marine waters of partially enclosed coastal areas. The results of the studies made it possible to assess the circulation of coastal marine waters and the change in certain indicators of water quality, including in the presence of various coastal protection facilities, based on 0-dimensional and system-dynamic models. The results obtained can be used to predict the state of water resources in coastal territories.

The Indian State of Goa has a coastal length of 104 Kms and the State contributes 1.85% to the marine fish production of the country. A study was conducted to assess the market efficiency indicators such as Gross Marketing Margin, Percentage Share of Fisherman in the Consumers Rupee (PSFCR) and the Coefficient of variation. The study revealed that high value fishes such as cobia, silver Whiting, seer fishes, prawns and milk shark recorded a comparatively higher price spread. Varieties which recorded higher PSFCR were speckled prawn (72.86%), cobia (70.31%), seerfish (69.98%), Brown shrimps or ginga prawns (69.43%), pony fish (67.58%) and milk shark (65.61%). At the point of first sales, high value fishes such as cobia, seerfishes, prawns and silver biddy had a co-efficient of variation of less than 10% indicating a higher price stability. High value fishes such as ribbon fishes, seerfishes, cobia, indian white prawn, barracudas, brown prawns, speckled prawns, kadal shrimps and half beaks were among the list of fishes which recorded a low co-efficient of variation of less than 10% at the point of last sales.

There is a lack of understanding of the main drivers that form the picture of biological communities of transitional waters in deltaic ecosystems under the influence of terrestrial sources. Analysis of hydrochemical parameters in relation to phytoplankton communities in the Ukrainian part of the Danube coastal zone (in August 2018) is the focus of current work. The goal was to identify patterns in the distribution of environmental parameters (salinity and nutrients) in the area of the shipping channel through the Bystry arm, as well as to assess the state of water quality. The ecological bioindicators approach using modern statistical methods, and ecological mapping shows sufficient achievements in interpreting the results. The indicators of salinity (mesohalobes) had better describe the character of the transportation of fresh riverine waters than salinity gradient. The composition of 35 indicator phytoplankton species corresponds to 3 and 4 water quality classes in the coastal zone. High N:P ratios showed an imbalance in the ecosystem as an indicator of production and destruction processes. Statistical maps of the indicator species distribution revealed the river current’s influence on the nearshore water mass. Ecological maps of surface and bottom variables show various environmental impacts resulting from dredging in the shipping channel and excavated soil dumping. Canonical correspondence analysis (CCA) and statistical maps revealed two pools of factors with oppositely directed effects on phytoplankton: salinity, on one hand, and nutrients, on the other. Miozoa and Chlorophyta have an opposite interaction with salinity and oxygen and can be ecosystem change indicators in further analysis

ABSTRACT Water bodies located in coastal areas are subject to human pressures and the loss of environmental quality. The objective of this study was to evaluate the environmental quality of the river Papaquara through water quality and river landscape, using the Trophic Index (TRIX) and Rapid Assessment Protocol (RAP). The study was developed in the watershed located in the north of the island of Santa Catarina, Florianópolis – SC, whose population increase in the summer is around 280%. The Trophic Index and the Rapid Assessment Protocol were evaluated in the pre-summer period, summer and after-summer in seven sample points along the inner areas (higher population density), median and outside the Papaquara river, plus two points in affluent. The river Papaquara showed up in great stress state, is classified as eutrophic, 77% of the samples and changed in 50% of the sampled area, as the TRIX index and RAP, respectively. The internal area registered up eutrophic and impacted in all periods analyzed. The median area and the outer decreased their water quality, due to summer activity, while there was no change in environmental quality by RAP. A significant correlation between the indices used indicated that the RAP should be used with caution to describe the condition of water quality. This analysis has submitted be more appropriate when used in river scale as a whole, but not isolated segments.

The paper summarizes the data obtained by analyzing the reaction of the coastal epilithic lichen cover tothe chemical parameters of water in reservoirs of different types and uses. The study was carried out on the shores of freshwater bodies (Lake Onega, Lake Ladoga, Lososinka, Suna rivers) with different anthropogenic pressures in the Republicof Karelia. At each place of study, the lichen cover was described at the survey sites (frame 10 x 20 cm) along the transectand water samples were taken for chemical analysis. The aim of the work is to identify indicators of the coastal epilithic lichen cover to indicate the quality of the aquatic environment and assess the state of coastal ecosystems. The lichen flora ofthe surveyed coasts of fresh water bodies has 53 species, the highest species diversity of lichens is characterized by placeswithout obvious sources of pollution – the Kivach reserve (29 species), the shores of Lake Ladoga (27 species) and the Botanical Garden of PetrSU (16 species), and in urban conditions ( Petrozavodsk), a large settlement (Yanishpole) and nearthe pulp and paper industry (Kondopoga), the number of lichen species is much lower (8, 5 and 4). Regression analysisshowed the dependence of the number of lichen species on the registration site on the concentration of phosphorus compounds in water (p < 0.05). A tendency to a decrease in species diversity and a decrease in the total coverage of lichens withan increase in nitrogenous compounds in water was noted. This made it possible to propose the epilithic lichen cover as anobject-indicator of the state of the coastal water environment under conditions of anthropogenic pollution of water bodies.

The coordinated relationship between ecology, economy and transportation is essential for regional sustainable development. Does the high-quality ecological environment mean the lagging development of economy and transportation, or does the rapid growth of the economy and transportation lead to the deterioration of the ecological environment? To shed new light on the complicated relationship between ecology, economy and transportation, our study aims to construct three comprehensive indicators, including an ecological index (EI), economic development level (EC) and transport superiority degree (TR), to reflect the systems mentioned above, and to measure the coordination of the three indicators’ development and evolution using a model of the coordination degree (CD). Specifically, and by applying methods for the indicators’ normalization, including superposition analysis and principal component analysis, the three indicators’ values are reasonably evaluated for measuring their coordination relationship. The above three indicators use data from 58 counties in Fujian province from 2000 to 2018 in our study. All three indicators show differences in the west and east of Fujian province; the EI is relatively low in the eastern coastal areas and relatively high in the western mountainous areas, the EC shows a relatively discrete and irregular distribution and the distribution pattern of the TR is almost the opposite of the EI. The CD shows a relationship among the three indicators, with the EI and EC coordinated in most counties and the EI and TR coordinated in most counties, while the highly coordinated counties are mainly distributed in the northwest and east coastal regions of Fujian province in 2000, and the northwest, south and northeast of Fujian province in 2018. More than 50% of the county EC and TR values are kept in a coordinated state, and are mainly distributed in the eastern coast and central part of Fujian province. Over 50% of counties’ CD between EI and EC, EI and TR and EC and TR are in a coordinated state. The CD of the EI and EC and TR, in most counties, are in a coordinated state, mainly distributed in the eastern coast and central areas of Fujian province. In other words, the findings show that the coordinated state of ecology, economy and transportation can be achieved at the county level of Fujian province. These conclusions have significant reference value for understanding regional sustainable development.

Abstract Annotation. The results of a study on the water quality, bottom sediments and coastal soil based on the level of anthropogenic pollution by heavy metal compounds and organic polutants are presented. The most commonly used integral and complex indicators used to assess the environmental safety of territories have been calculated. A comparative analysis, using the Shannon Biodiversity Index, highlighted the total pollution index (Zc) as the most informative, among those analysed, in terms of the impact of anthropogenic pollution on biota. The results established a methodology for assessing the environmental safety of territories that needs to be improved. By using the Maximum Permissible Exceedance (MPE) indicator, objective data will be available when determining the negative impact of pollution of natural environments on the state of ecosystems.

The main aim of our paper is to study peculiarities of two periods, i.e., the pre-conflict period (2004–2013) and conflict period (2014–2018), in the context of the impact of the demographic structure of the population on the economic growth and development of coastal regions of Ukraine. In the first step of the analysis, we investigate the relationship between the demographic shifts and selected economic indicators, using the Pearson’s correlation coefficient. In the next step of the analysis, we focus on the quantification of the impact of demographic indicators on the economic variables, based on the panel model with fixed effects. The received results confirm that the influence of the demographic stricture on the economic state of coastal regions changed significantly in the conflict period in comparison with the pre-conflict period, especially concerning income, unemployment, and the openness of the economy. Additionally, our findings show that while economic differences existed between the Azov Sea regions and the Black Sea regions in the pre-conflict period, they disappeared due to the economic deterioration of the Azov Sea regions during the conflict period. It is concluded that war affects adversely the population’s demographic structure, which inhibits the growth and economic development of Ukrainian coastal regions.

Abstract Climate change vulnerability is highly counter-productive for agriculture among the arid and semi-arid regions. The study constructs the agriculture vulnerability index for Karnataka, a south Indian state. The state has faced frequent climate-related shocks in the last decade. The district-wise vulnerability index is estimated using longitudinal data considering exposure, sensitivity and adaptive capacity as sub-indices. The results show that the districts in the north interior region of Karnataka are highly vulnerable to the climate change followed by the districts in the south interior and coastal regions. There is an urgent need to prioritize the most vulnerable districts while formulating the development policies to minimize the risk of climate change on agriculture. Specific technical knowledge and support need to be made available to the farmers for informative climate resilience action.

In the present paper, the coastal risk is assessed, at a regional scale, to produce a risk map that will help to prioritize policies and economic resources in coastal management and planning activities. The DPSIR method is here used taking into account processes and cause/effect relationship between Drivers and Pressures, which induce an alteration of actual State and, hence, Impacts on the environment, society and economy. The study area is located in South Italy (Apulia region), where the Risk Index is calculated and mapped for all municipalities facing the Adriatic and Ionian Seas. Both coastal Vulnerability and Exposure Indexes are firstly calculated according to the procedure suggested in the EUrosion project (EU model) as the product of specific indicators describing the state of coastal zones, their natural characteristics and both natural and anthropic pressures. Based on both EU model results and knowledge of states and pressures of the study area, a new modified model is then proposed (Mod.E.M.) and final risk maps compared. The comparison shows that new Vulnerability and Exposure indexes better describe the ongoing coastal processes and pressures and allow us to identify hot-spot sites where more detailed analyses could be further focused on. The Mod.E.M. has more than just a local significance since the case study includes coastal areas with so different characteristics, that it can be easily applied to other coastal regions. Moreover, to take into account climate change effects, Risk Index is evaluated under Representative Concentration Pathways R C P 4.5 and R C P 8.5 , mainly affecting the sea level rise and the storm surge level.

Despite the importance of coastal areas to sustainable development, they are poorly known by the public or even by decision-makers. This undermines consistent action towards their protection. Existing data and information, published in very complex language, tend to be restricted to academic use. The Coastal Web Atlas as the one developed here is a tool that makes this information more accessible to managers, by preserving, integrating, comparing, and sharing data as smart maps. The spatial analysis based on multiple impact indicators facilitates the correlation of causes and effects. The Coastal Web Atlas is available to a broad audience and it could be a strong instrument for spatial planning and oversight. The authors propose to improve coastal area management by using colors on maps to decode scientific language to friendly language and to publish it on a geoportal. This technology promotes the use of collected data and enables collaborative work.

The present paper is an attempt to test the applicability of the trophic state index (TRIX) for scaling the eutrophication along the Bulgarian Black Sea coastal zone in concert with a number of chemical and biological descriptors aimed at selection of relevant indicators of marine coastal area ecological quality. The following environmental parameters have been considered: to, salinity, nutrients - inorganic P, N and dissolved Si, dissolved oxygen and oxygen saturation, phytoplankton - taxonomic structure, abundance and biomass, chlorophyll a, zooplankton - taxonomic structure, abundance and biomass. Principal Component Analysis was applied in order to figure out and score the most relevant combination of parameters to discriminate between sites and select representative descriptors (pressure/state) of eutrophication. The following variables are defined as relevant descriptors for classification of the sites: nutrients (N, P, Si) and their molar ratios (N:P and Si:P), the capacity of the system to produce and sustain organic matter (chlorophyll a, phytoplankton biomass), phytoplankton taxonomic dominance (Bacilariophyceae:Dinophyceae biomass ratio), grazing pressure (phytoplankton:zooplankton biomass, Bacilariophyceae:Copepoda), plankton diversity index (Hb and Ha) and the trophic state index (TRIX). The investigated sites under a different anthropogenic impact are classified according to selected descriptors and their water quality state.

In oil-producing regions, oil pollution occurs, which, among other things, causes problems related to conservation of the region’s biodiversity. Therefore, acquisition of knowledge about the state of the unique nature of Northern Caspian, which is under an intensified anthropogenic press, and study of the current state of marine and coastal biota, is an urgent problem for modern Kazakhstan. The territory is located in a desert zone, in the subzone of steppificated northern deserts. In the zonal terms, this is a transitional azonal band between the subzones of the mid-latitude absolute and northern steppificated deserts. Even more significantly, it is located between the contrasting ecosystems of the sea and land. Such a geographical location predetermines the heterogeneity of spatial differentiation and the dynamics of vegetation. Moisture and salinization regimes are the main limiting factors for the botanical composition of communities. In this regard, the vegetative cover is characterized by a poor floristic and phytocenotic diversity and a simple structure. This is also due to the youth of the territory, periodic transgressions and regressions of the Caspian Sea and a constant influence of the surging sea.
As a result of intensive grazing use of the territory in the previous years, there are areas of saltwort-sagebrush degraded vegetation in the areas of increased concentration of agricultural animals, characterized by a lower vitality of Artemisia, its thinning and abundant growth of annual saltworts: Ceratocarpus arenarius, Climacoptera brachiata, Salsola paulsenii and Salsola nitraria that reduce significantly the grazing characteristics of grasslands and are indicators of anthropogenic activity.
In recent decades, the society has increasingly used information about the state of the natural environment in its activities. This information is needed in the daily life of people, in the management of the economy, in construction, in emergency circumstances – to alert people of the imminent natural calamities. However, changes in the state of the environment also occur under the influence of biospheric processes associated with human activities. To determine the contribution of anthropogenic factors to these changes is an important and difficult task.
Abundance of species and phytobiotic structure are important indicators of the state of the environment, the degree of anthropogenic disturbance and pollution. As a result of the research, data on flora, composition and structure of vegetation will be obtained

Forward or backward travel times and residence time distributions are robustly simulated and visualized on the computational grid. These steady-state indicators, precomputed at fine grids, are used to generate optimal locally refined grids for efficient transient solute transport simulations.

The present paper aims to investigate the relative sea-level and the coastal evolution during the Holocene in the Rio de Janeiro coastline, based on geological and biological indicators. Using topographic survey, excavation and coring, and 14C dating of these coastal deposits and beachrocks outcrops, we have reconstructed a sea-level curve for the Holocene. For the first time on the Brazilian coast it was identified a negative record of relative sea-level during Late Pleistocene and Early Holocene transition. After the transition, a relatively rapid increase of sea-level began. At approximately at 8500 cal yr BP, the sea-level was 0.5 m below the current level, was overtaken for the first time in the Holocene, at approximately 7500 cal yr BP. The maximum level of +2.5 m was reached between 4770 and 4490 cal yr BP. At the point of maximum transgression, the sea-level began a general behavior of lowering until the present. These results confirm other data already obtained elsewhere along the Atlantic coast of South America. The results of this study are consistent with previous researches and they help to refine the Holocene sea-level record along the Brazilian coast.

Degradation of the small lowland river Temernik as a consequence of the development of the city Rostov-On-Don negatively affects not only the urban ecology, but also the image of riverine areas, which gradually led to “rejection” of the urban fabric from the river. In terms of the constant compaction of urban fabric and increasing deficiency of pedestrian spaces, rehabilitation of the Temernik River valley manifests as a possibility of a new stage of development of the urban infrastructure. In the course of studying the riverine areas, the author assess three indicators: access, populace, and landscape. The author develops visual triangle-based diagrams, where on three of its axes are plotted the approximate values of the aforementioned indicators. The analysis of the diagrams allows determining the boundaries of areas, which can be potentially transform into the public recreation spaces. The author proposes the approach towards examination of the Temernik River valley; carries out differentiation of coastal areas; outlines the territories that hold potential of being transformed to the public recreation spaces; develops the pattern of organization of public recreation spaces formed within the coastal area of the Temernik River, taking into account the implementation of eco technologies and cognitive approach towards designing urban spaces. The formation of hybrid spaces, which are able to integrate eco technologies, landscape, pedestrian spaces, infrastructure, and others underlie the creation of spatial concept of coastal areas of the Temernik River.

Abstract The current paper aims at analyzing the species structure of the phytoplankton community of two reservoirs on the territory of South Ural. The given water bodies are of different trophicity, namely, oligotrophic Lake Turgoyak and oligomesotrophic Lake Uvildy. Both lakes, being natural monuments, are subject to intensive recreational use. A large flow of tourists is a serious problem for the ecological state of the water bodies coastal areas. Also, tourist activities can affect the state of aquatic biocenoses. In this work, the degree of recreational degression of the selected study sites was assessed. The analysis was carried out according to the state of landscapes, vegetation and trampledness of the surveyed area. Based upon the research the current paper reveals spatial patterns in the distribution of recreational load on the coastal geosystems and the level of anthropogenic transformation of the territory. Mainly due to the high density of recreational centres and camping areas, the coastal area is characterized by a high degree of regression. Some signs allow forecasting changes in the species composition of phytoplankton communities and the trophic status of the lakes depending on the degradation of the coastal zones. Diatoms (Bacillariophyta) have been dominant in plankton phytocoenosis of Turgoyak and Uvildy. At the same time, in the oligomesotrophic lake (Uvildy), the number of diatom species is significantly reduced in areas with a higher degree of regression. Thus, diatoms are sensitive indicators of anthropogenic impact on aquatic ecosystems. Green and blue-green algae biodiversity has grown in the water body. However, no relationship was found between their species diversity and the level regression. But the following tendency is observed for the oligotrophic Lake Turgoyak. The species diversity of green algae grows with an increase in the degression degree. To forecast the further state of the studied water bodies, the revealed patterns in the change of the phytoplankton species structure depending on the degradation level of the coastal territories can be used as eutrophication signs.

This paper presents a coastal migration index (CMI) useful for decision-making in the current scenario of sea-level rise (SLR) due to climate change. The CMI includes coastal human population density, degree of urbanization, and coastal-flooding penetration. Quantitative and qualitative statistical techniques and the geographic information system ArcGIS View 9.0 were used. Further, a panel of fifteen international experts in coastal management issues was consulted to establish and validate the CMI. Results led to three index components based on 22 indicators. CMI was applied in the state of Tamaulipas, Mexico and in Santiago de Cuba province, Cuba. According to CMI estimates, the risk levels associated with SLR for human settlements analyzed in Mexico and Cuba were 5.3% and 11.0%, respectively. The most severely affected communities will require resettlement. Meanwhile, the CMI determined that 15.8% of the Mexican territory studied will be able to withstand the effects of SLR through the management of engineering works that will protect human settlements. The CMI determined that 79.0%, in the case of Tamaulipas, as well as 89.0% of the Cuban territory, will not require new policies or guidelines to promote conservation and protection of coastal natural resources. Lastly, the method used allowed for creation of a CMI stoplight map useful to coastal decision-makers to adopt sound management actions.

A formal village/neighbourhood planning process is typically focused on three planning levels (national, regional and local) and is usually linked with administrative units of the territory (state, region or municipality). The local planning level (village or neighbourhood) “pocket plan” is a development challenge for spatial planners. The small coastal village Tuja in Latvia was taken as a pilot territory for “pocket planning” due to the unique location; biodiversity and ecosystems; significant natural, cultural, economic and social values; specific interests; and the needs of the involved local society. All these factors create a dynamic flow of data and information. Geographic information systems (GIS) are widely used as planning support systems. GISs for pocket plans must accommodate the special needs of communities in villages and neighbourhoods. Ensuring the availability of information in dynamic real time is an opportunity to build both community integration in specific environments and to understand the future plans of the territory. Access to a WEB-GIS (internet GIS) provides possibilities for every person with a mobile phone to use and update information. Static and statistical information is generally used for spatial planning. For pocket plans, the data and information flow has to be dynamic and has to interact with non-professional users. The special wishes and needs of every member of a community must be accommodated by a pocket plan for the well-being of the people and the sustainability of the surrounding territory. Small territory planning involves a very narrow circle of individuals or communities that identify spatial development needs for the future, which includes the socio-economic, cultural, historical, environmental and climate change scenarios. In order to assess the development opportunities and needs of such areas, the detection, accumulation and monitoring of reliable data is necessary. Methodically derived data (facts) provide objectivity and transparency. Currently, as information between the present and the past is able to circulate very fast, analysis of the current situation to forecast the future and show different constructed realities (scenarios) using a GIS is necessary. Therefore, to explore and determine a local needs-based and smart spatial planning approach, we must identify indicators that can be used for the short-term and long-term analysis of specific territories in coastal areas.

AbstractStandards based on fecal indicator bacteria (FIB) have traditionally been used by the U.S. Environmental Protection Agency to determine when recreational waters are contaminated by fecal and sewage inputs. Studies in tropical and subtropical areas, however, have shown that these same standards cannot reliably be used in these environments to determine when waters are contaminated by sewage. This is because soil, sediments, water, and plants have been shown to be significant indigenous sources of FIB in tropical/subtropical climates. In these climates, alternative fecal indicators, such as Clostridium perfringens and F+RNA coliphages, may be more reliable markers of sewage contamination, because these organisms are generally found in low concentrations in the environment. In the State of Hawaii, monitoring data relating to FIB (fecal coliform, Escherichia coli, enterococci) and alternative indicator microorganisms (C. perfringens, F+RNA) in recreational waters has been obtained for the Island of Oahu, but similar data are lacking for other islands within the state. The major goal of this study was to monitor water samples obtained from the Nawiliwili watershed on the Island of Kauai for traditional FIB (fecal coliform and enterococci) as well as alternative fecal microbial indicators (C. perfringens, somatic coliphages, and F+RNA coliphages). Results for FIB concentrations on the Island of Kauai followed a similar trend as data obtained from the Island of Oahu. In addition, in areas like the Island of Kauai where cesspools are prevalent, monitoring for F+RNA and somatic coliphages may provide more reliable data in the detection of subsurface contamination of streams by cesspool waste, which can then lead to the pollution of coastal waters. Finally, genotyping of F+RNA phages obtained from the study sites provided additional evidence that human cesspool contamination was occurring within the Nawiliwili watershed.

Full textAbstract:
Coastal rural communities, being intricately associated with their ecological settings, are often highly vulnerable to climate change. Amongst the many approaches of reducing the coastal vulnerabilities and achieving climate change adaptation, a potential solution is to improve risk governance through integrated coastal zone management. The coastal risk governance signifies not only the actions of the state but also of other stakeholders, especially the local communities. Community-based approaches have also for long been advocated for effective adaptation and mitigation against climate adversities. While human-nature interactions can significantly influence disaster risks, this research makes an attempt to understand various decisions and choices that a coastal rural community makes based on such interactions to mitigate and manage the climate-induced adversities. Through structured interviews, this research first identifies the significant domains that reflect on the prevailing human-nature interactions, after which the choice modelling technique is utilized to comprehend the community priorities for better climate risk governance, with a specific focus on coastal rural settlements of Katrenikona (Andhra Pradesh, India). The application of this methodology resulted in the formulation of a baseline for local coastal governance, which can be useful for informing various levels within local governments. The baseline consists of an assessment of the different community resilience domains derived based on the prevailing interactions of local communities with their surrounding ecological elements and measured by indicators of local coastal governance. The concept and method for measuring coastal risk governance based on community preferences are potentially replicable, and it can help to track the progress towards longer-term coastal management and local climate adaptation goals. At the same time, it can be turned into a self-evaluation tool to assist the local governments in reflecting on pertinent pathways involving community actions for effectively managing various climate risks and ecological impacts.

The economic significance of the Russian Arctic for Russia is determined by its geographical position, huge natural resource, transport and logistics potential. A characteristic feature of the Arctic economy is in its pronounced maritime character, which determines the need for an integrated approach to the state management of maritime economic activities in the Arctic regional direction, including measures of state support for the infrastructural development of regional maritime economic complexes. We can talk about the approaches of integrated coastal zone management (ICZM), well-tested in the world practice, considering sea use as an integral management object. The methodology of integral management proposed in the article is aimed at creating a systemically balanced economic structure of maritime use, including through cluster technologies for the spatial development of water-territorial production complexes (ATPC), as well as reducing conflicts between various participants in economic activity in the process of competitive use of coastal spaces and marine resources. and preservation of the marine environment. From this point of view, the formation of a Coastal Policy should be aimed at coordinating strategies for the development of industries (and individual enterprises) in the interests of the overall development of coastal zones based on logistic principles of cross-sectoral planning. The development and adaptation of mechanisms for the interaction of integrated and sectoral planning necessitate a comprehensive assessment of the effectiveness of the maritime economic complex (MEC) in the region's economy, including the effectiveness of the activities of state authorities in creating favorable conditions for the sustainable development of the region's maritime complex. Such an assessment can be carried out on the principles of constructing a system of balanced indicators that characterize the complex characterizing the maritime complex and its impact on the region's economy.
