Influence of climate change, overfishing and COVID19 on irregular migration in West Africa

Throughout 2020, according to the Spanish Ministry of Home Office, 23,023 irregular migrants reached the coasts of the Canary Islands in Spain, 757% more than the previous year. The migrants left from the coasts of West Africa, mainly from Senegal, trying to reach the nearest European Union (EU) territory. Apart from the migrants who arrived in the Canary Islands, nearly 1,500 stayed on the way, and 594 of them died drowned or of dehydration. Behind this migratory tragedy, there is a combination of factors, with three essential ones operating synergistically: climate change, which is affecting agriculture, fishing and exacerbating coastal erosion;overfishing, which is depleting regional fisheries;and the COVID-19 pandemic, which, in addition to the victims caused, has left the region without tourism, and with an economy in recession. This paper reviews these causal factors, highlighting his influence on migration and the responsibility of migrants receiving countries – especially those in the EU – for the causes of migration.

A brief overview of the issues faced by Harmful Algal Blooms along Johor straits

Urbanization of coastal areas worldwide has increased due to an increase in the global population. The production of sustainable aquaculture is greatly impacted by a surge of this urbanization. In certain countries, particularly for individuals with more limited space in metropolitan areas, such as along Johor's coastal area, aquaculture might well be a good strategy to maintain food availability (continuous production plus high-quality meals). Consequently, the adoption of aquaculture along the Johor's coastal area has lead to Harmful Algal Blooms (HAB). This paper examines the evolution of the aquaculture industry of Malaysian Johor coastal areas in relation to HABs. In addition to HABs, the aforementioned metropolitan regions confront diverse economic and geographical obstacles when attempting to increase their aquaculture production sustainably. Those problems are therefore addressed using a variety of operations as well as surveillance techniques in this brief overview. Lockdowns and border prohibitions caused by the continuous COVID-19 infection have had a global impact. These logistical difficulties in the seafood industry have increased dependency on imported supplies. It is suggested that international decision- making, supervision, and knowledge exchange can successfully solve the challenges urbanized areas have in ensuring sustainable food security through the evolution within the aquaculture sector.

Analysis and Countermeasures of the Influence of COVID-19 on the Commodity Category of Port Export in China: Taking Shanghai Port as an Example

Su, B.;Guan, C.;An, Q., and Wang, Q., 2020. Analysis and countermeasures of the influence of COVID-19 on the commodity category of port export in China: Taking Shanghai Port as an example. In: Liu, X. and Zhao, L. (eds.), Today's Modern Coastal Society: Technical and Sociological Aspects of Coastal Research. Journal of Coastal Research, Special Issue No. 111, pp. 298–301. Coconut Creek (Florida), ISSN 0749-0208.Since the end of 2019, the novel coronavirus has spread rapidly, which has affected the economy, social interaction, and foreign trade, both in China and around the world. Import and export trade has become an organic part of China's national economy. Import and export trade accounts for nearly 35% of the national economy, which is a major part of China's economic growth. This article takes Shanghai Port as an example, collecting and analyzing the exporters of Shanghai Port in China from January to May 2020. Compared with the relevant data of the same period in 2019, this article discusses the major commodity categories that are affected by the epidemic situation in the export trade volume of Shanghai Port, giving countermeasures according to the influence situation in order to stabilize the quantity of this category in the future and reduce the risk of lower port trade volume of the export commodity categories affected by public health emergencies in China's port trade. At the same time, some suggestions and countermeasures are given to the ecological environment problems affecting the sustainable development of ports.

Low‐Altitude UAV Imaging Accurately Quantifies Eelgrass Wasting Disease From Alaska to California

Declines in eelgrass, an important and widespread coastal habitat, are associated with wasting disease in recent outbreaks on the Pacific coast of North America. This study presents a novel method for mapping and predicting wasting disease using Unoccupied Aerial Vehicle (UAV) with low‐altitude autonomous imaging of visible bands. We conducted UAV mapping and sampling in intertidal eelgrass beds across multiple sites in Alaska, British Columbia, and California. We designed and implemented a UAV low‐altitude mapping protocol to detect disease prevalence and validated against in situ results. Our analysis revealed that green leaf area index derived from UAV imagery was a strong and significant (inverse) predictor of spatial distribution and severity of wasting disease measured on the ground, especially for regions with extensive disease infection. This study highlights a novel, efficient, and portable method to investigate seagrass disease at landscape scales across geographic regions and conditions.Alternate abstract:Plain Language SummaryDiseases of marine organisms are increasing in many regions worldwide, therefore, efficient time‐series monitoring is critical for understanding the dynamics of disease and examining its progression in time to implement management interventions. In the first study of its kind, we use high‐resolution Unoccupied Aerial Vehicle (UAV) imagery collected to detect disease at 12 sites across the North‐East Pacific coast of North America spanning 18 degrees of latitude. The low altitude UAV visible‐bands imagery achieved 1.5 cm spatial resolution, and analysis was performed at the seagrass leaf scale based on object‐oriented image analysis. Our findings suggest that drone mapping of coastal plants may substantially increase the scale of disease risk assessments in nearshore habitats and further our understanding of seagrass meadow spatial‐temporal dynamics. These can be scaled up by searching for environmental signals of the pathogen, for example, with surveillance of wastewater for signs of Covid in human populations. This application could easily apply to other areas to construct a high‐resolution monitoring network for seagrass conservation.

Measurement and Evaluation of Convergence of Japan’s Marine Fisheries and Marine Tourism

This study attempts to examine the convergence development of the marine fishery (MF) and marine tourism (MT) industries of Japan through the theory of industrial relevance. First, the current MF and MT situation in Japan is introduced to analyze the mechanism of the integration of the two industries. Second, a Vector Autoregression Model (VAR) is built to examine the relationship between MF and MT. In addition, the shock potential contributions of the MF and MT industries are identified using impulse response and variance decomposition. Results show that the impact of MF on MT is more significant than that of MT on MF. However, the interaction between MF and MT tends to stabilize in the long run. Third, the industrial integration case of Japan’s Himakajima Island is selected to analyze the MF and MT integration mechanism. The integration of MF and MT can reduce transaction costs, make full use of labor, and promote the development of the local economy. Therefore, attention should be paid to the integration of the MF and MT industries, rather than partial implementation, to balance the development of the marine economy. Finally, relevant suggestions and measures are presented for marine industry transformation and upgrading, industrial integration, and green ecological development.

First Nations Capacity-Building through Geographic Response Strategy Development during COVID-19: Supporting Data Management for a Remote Field Season during a Global Pandemic

A group of British Columbia North Pacific Coast First Nations (NPC Nations) have been actively developing Geographic Response Strategies (GRS) within their territories since 2018. A multi-year project plan included three years of field work (2019-2021), during which technical experts would support First Nations communities in transferring knowledge and practice. The implementation of lockdowns, travel restrictions, and public health advisories beginning in March 2020 substantially changed the planned approach and ultimately spurred novel approaches to remotely supporting field surveys and mentoring First Nations community members to lead oil spill response surveys. To enable the continuation of field work, a contracting team worked closely with the NPC Nations to create a strategic approach to collaborate through web-based conference platforms and cloud-based GIS. There were several imperatives to continue this work – First Nations communities view marine oil spill planning as a top priority based on past spills in their territories and risks from coastal shipping. The project funding was grant-based and time-bound, expiring at the end of FY2021-22. Despite the pandemic, the participating First Nations still had a successful field season with roughly 40 combined days in the field from April 2020 to November 2021, with approximately 221 sites surveys and close to 500 tactics developed. Through innovation, collaboration, and trial and error, 12 BC First Nations continued to develop GRS to help strengthen their marine response capacity while adhering to the strict COVID-19 guidelines set in place by their local communities, which were often more stringent than provincial and national policies to protect their elders and other vulnerable community members in remote areas with limited medical facilities. This paper discusses the specific modifications to the field surveying process driven by the pandemic and the technology tools used to communicate and capture data accurately. In addition, this paper examines how Geographic Information System (GIS) was incorporated into the GRS development, including GIS training for community members and the use of tablet-based applications to gather field data. It describes a successful approach to peer-to-peer knowledge transfer across First Nations communities, building a community of practice and mutual support. Finally, this paper reports lessons learned and suggests best practices to continue broadening the marine response and preparedness capacity within the BC First Nations. © 2022 44th AMOP Technical Seminar on Environmental Contamination and Response.

COVID-19 Pandemic: Microfinance and Social Sustainability of Grameen Bank Borrowers in South-West Bangladesh

As important as social sustainability is to the sustainable development agenda, there is a lack of research to clearly define and operationalize the concept. The purpose of this research is to add to the existing body of knowledge by developing a comprehensive scale for evaluating social sustainability and microfinance at the vulnerable level. A multidimensional concept of social sustainability, we argue, incorporates equity, diversity, social cohesion, and quality of life as well as democracy and governance. An incomplete picture of social sustainability may result if these dimensions are ignored. Factor analysis is used to examine the scale's validity, reliability, and dimensionality. Using microfinance as a case study, we demonstrate how the social sustainability scale can be put to use in practice. Women microfinance users in rural and coastal areas in Satkhira District of Bangladesh's southwest were surveyed for this paper using data from a questionnaire survey that included 223 respondents from rural and coastal areas (Shyamnagar and Kaligonjupazillas). Improved microfinance has a positive and significant impact on various aspects of social sustainability and overall social sustainability, according to this new research.

Coastal Scenic Quality Assessment of Moroccan Mediterranean Beaches: A Tool for Proper Management

This paper focuses on the study of landscape quality of Moroccan Mediterranean coastal areas, with a view to distinguishing exceptional beaches with high scenic value. The main characteristics of 50 beaches along the studied coast were assessed using a coastal scenic evaluation system based on a set of 26 selected parameters, including physical (18) and human (8) parameters. Each parameter was examined via a five-point rating scale, ranging from presence/absence or poor quality (1) to excellent quality (5). A decision index (D) is afterward obtained and used to classify sites into five classes: Class I: D ≥ 0.85, which included 9 sites (18%);Class II: 0.85 > D ≥ 0.65, 10 sites (20%);Class III: 0.65 > D ≥ 0.40, 8 sites (16%);Class IV: 0.40 > D ≥ 0.00, 16 sites (32%);and Class V: D < 0.00, 7 sites (14%). The sites of Belyounech 2, Maresdar, El Hwad, and Dalya are the best examples of Class I and represent extremely attractive coastal landscapes. The sites of Ghandouri, Tangier Municipal, M’Diq, Martil, and Tangier Malabata are examples of degraded urban sites that are very unattractive due to high human pressures. Management efforts in Moroccan coastal landscapes can strengthen the control of human activities and improve the scenic value of the sites. Class II beaches, such as Mrisat, Souani, Taourirt, and Sfiha, could improve and upgrade to Class I through litter cleaning and a regular maintenance program. Using the same principle, Class III sites, such as Sidi Amer O Moussa and Sidi Driss, could improve and upgrade to Class II. Indeed, litter and sewage appear as the main factors of degradation of Moroccan coasts, and many excellent beaches are strongly affected by them. This should be a wakeup call to the Moroccan authorities to take urgent and appropriate management measures.

Demand for Domestic Marine and Coastal Tourism

Domestic marine and costal tourism has increased in importance over the last number of years due to the impacts of international travel, environmental concerns, associated health benefits and COVID-19 related travel restrictions. Consequently, this paper conceptualizes domestic marine and coastal tourism within an economic framework. Two logit models examine the factors that influence participation in the coastal day trips and overnight stays markets, respectively. Two truncated travel cost models are employed to explore trip duration, one analyzing the number of day trips taken and the other examining the number of nights spent in marine and coastal areas. Although a range of variables predict participation, no one variable had a significant and consistent affect in every model. A division in access to domestic marine and coastal tourism is also observed based on variation in household income. The results also indicate a vibrant day trip market and large consumer surpluses. The decision to use logit participation models and travel cost models applied to day trips and overnight stays is a direct result of the audiences this paper aims to inform. Firstly, by presenting the decision making process for domestic marine and coastal tourism in this depth, evidence based decision makers can gather a better understanding of how domestic tourist decided to participate in marine and coastal tourism, who the larger beneficiary are of the different types of marine and coastal tourism and how policy focused solely on overnight stays can adversely affect particular segment of society, often those less well off financially. Secondly, the academic literature has presented a dearth of information comparing day trip participation to overnight stays in marine and coastal tourism, as such, this paper provides a valuable source of information.

Evaluating Tourist Experience of Rural Homestays in Coastal Areas by Importance–Performance Analysis: A Case Study of Homestay in Dapeng New District, Shenzhen, China

In recent years, the rural homestay has developed rapidly against the background of rural-revitalization policies. However, in early 2020, COVID-19 broke out in China, and the homestay industry was faced with a great challenge. It was difficult for self-employed homestays to resist the risks of the pandemic. As a result, defective operation and business failure occurred in some regions. However, rural homestays with a background in the brand, chain and cluster development mode persisted in the market with a diversity of operation principles. This paper tries to set up an evaluation system for understanding the occupancy needs of tourists, in order to improve the ability of rural homestays to resist risks. The article offers a methodology for assessing the tourist experience of rural homestays in coastal areas, with homestays in Dapeng New District of Shenzhen taken as the research objectives. Then, the evaluation system of rural homestays is set up from the perspective of tourist experience. Based on the results of a questionnaire survey and interviews of operators, this paper proposes the tourist experience–importance analysis in Jiaochangwei and Xichong by the importance–performance analysis (IPA) method. Finally, it suggests policy recommendations that can resist high risk based on tourist experience, for the sustainable development of rural homestays in China.

Harnessing Offshore Wind Energy along the Mexican Coastline in the Gulf of Mexico—An Exploratory Study including Sustainability Criteria

Mexico has more than 40 years of researching, investing, and obtaining electric power through wind energy. Within the country, there are highly windy areas, such as the Isthmus of Tehuantepec or the state of Tamaulipas, and there are about 2500 MW installed and 70,000 MW tested, all onshore. There are still no offshore wind farms in Mexico, despite having two main coasts, the East and the West, with the Gulf of Mexico and the Pacific Ocean, respectively. Although the Mexican coastal states of the Gulf of Mexico are Tamaulipas, Veracruz, Tabasco, Campeche, and Yucatán, this work focuses on the study and feasibility of offshore wind energy use on the coasts of the states of Tabasco, Campeche, and Yucatán. This is because of the availability of data in that region;however, sustainability criteria that can be used in other regions are also presented. MN1 -https://media.proquest.com/media/hms/PFT/1/QWW6N?_a=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%3D%3D&_s=bqizVgXfGC1ulIdNL9ljg0AkJAU%3D ERRA-2 and ERA5 data were used employing WAsP and Windographer software. It was found that the capacity factor in the area of Tabasco, Campeche, and Yucatán is 32%, 37%, and 46%. It can be noted that, in the WF100% scenario, each of the wind farms could contribute more than 35% of the region’s electricity consumption;those of Campeche and Yucatán stand out with contributions of more than 70%.

Significant Loss of Ecosystem Services by Environmental Changes in the Mediterranean Coastal Area

Mediterranean coastal areas are among the most threated forest ecosystems in the northern hemisphere due to concurrent biotic and abiotic stresses. These may affect plants functionality and, consequently, their capacity to provide ecosystem services. In this study, we integrated ground-level and satellite-level measurements to estimate the capacity of a 46.3 km2 Estate to sequestrate air pollutants from the atmosphere, transported to the study site from the city of Rome. By means of a multi-layer canopy model, we also evaluated forest capacity to provide regulatory ecosystem services. Due to a significant loss in forest cover, estimated by satellite data as −6.8% between 2014 and 2020, we found that the carbon sink capacity decreased by 34% during the considered period. Furthermore, pollutant deposition on tree crowns has reduced by 39%, 46% and 35% for PM, NO2 and O3, respectively. Our results highlight the importance of developing an integrated approach combining ground measurements, modelling and satellite data to link air quality and plant functionality as key elements to improve the effectiveness of estimate of ecosystem services.

Stakeholders’ Perspective on Groundwater Management in Four Water-Stressed Mediterranean Areas: Priorities and Challenges

Recent studies highlight the fragility of the Mediterranean basin against climate stresses and the difficulties of managing the sustainable development of groundwater resources. In this work, the main issues related to groundwater management have been identified from the stakeholder’s perspective in the following four representative water-stressed Mediterranean areas: the coastal aquifer of Comacchio (Italy), the Alto Guadalentín aquifer (Spain), the alluvial aquifer of the Gediz River basin (Turkey), and the Azraq aquifer (Azraq Wetland Reserve, Jordan). This has been achieved by designing a methodology to involve and engage a representative set of stakeholders, including a questionnaire to learn their point of view concerning the current management of aquifer systems and their experience with the already available tools for groundwater resource management, such as monitoring networks and numerical models. The outcome of the survey has allowed us to identify both particular and common challenges among the four study sites and among the various groups of stakeholders. This information provides valuable insights to improve the transfer of scientific knowledge from the research centers to the authorities managing the groundwater resources and it will help to plan more effective research activities on aquifer management. The proposed methodology could be applied in other aquifers facing similar problems.

Baseline Marine Litter Surveys along Vietnam Coasts Using Citizen Science Approach

Marine litter is a significant threat to the marine environment, human health, and the economy. In this study, beach litter surveys along Vietnamese coasts were conducted in a local context to quantify and characterize marine litter using the modified GESAMP marine litter monitoring guideline. A total of 21,754 items weighing 136,820.2 g was recorded across 14 surveys from September 2020 to January 2021. Plastic was the most abundant type of litter by both quantity (20,744 items) and weight (100,371.2 g). Fishing gear 1 (fishing plastic rope, net pieces, fishing lures and lines, hard plastic floats) and soft plastic fragments were the most frequently observed items (17.65% and 17.24%, respectively). This study not only demonstrates the abundance and composition of marine litter in Vietnam, it also provides valuable information for the implementation of appropriate preventive measures, such as the redesign of collection, reuse, and recycling programs, and informs policy and priorities, with a focus on action and investment in Vietnam. Moreover, insights from this study indicate that citizen science is a useful approach for collecting data on marine litter in Vietnam.

Trends in the Environmental Conditions, Climate Change and Human Health in the Southern Region of Ukraine

The Kherson, Mykolaiv, Odesa, and Zaporizhzhia oblasts, being adjusted to the coasts of the Black and Azov Seas, are located in the steppe zone and constitute the southern region of Ukraine. The environmental parameters and health indicators of the population of the region are sensitive to the impact of natural (e.g., climate change) and anthropogenic processes. An analysis of satellite remote sensing data (NOAA NDVI time series) for the assessment of vegetation condition demonstrates an increase in frequency and duration of drought events in the region during the last few decades. It may have a relation to climate change processes. Data analysis of local meteorological observations over the past 100 years proved alterations of some bioclimatic indexes. The Equivalent Effective Temperature (IEET) increases in winter and summer (due to the increasing repeatability of high anomalous temperatures) and remains stable in spring and autumn seasons. The increasing number and variability of climate anomalies can provoke an increase in cardiovascular and some other diseases in the local population. At the same time, an analysis of the statistical data of health indicators of the population (such as morbidity of digestion, breathing, and the endocrine and circulatory systems) shows a tendency to decrease morbidity (contrary to the indicators of the mountain regions’ population, which have higher values of life expectancy). Interrelations between environmental, climate change, and population health indicators in the Black Sea region are being discussed.

Influence of Thermal Modification and Impregnation with Biocides on Physical Properties of Italian Stone Pine Wood (Pinus pinea L.)

Featured ApplicationIn recent decades, the importance of wood has also been increasing for outdoor intended use. A more sustainable approach has turned the attention from faraway tropical forests to local wood, that is, European species. Unfortunately, most of the species are not durable;thus, in order to utilize them in outdoor conditions, protection must be provided. Stone pine (Pinus pinea) is one of the most common tree species in the Mediterranean region, with a great potential in applications with higher added value, instead of being used only for burning or packaging. This investigation explores methods for an improvement of the service life of stone pine sapwood using impregnation and modification techniques.The sudden availability of Italian stone pine (Pinus pinea L.) wood due to the infestation of pathogenic fungi and insects highlighted the need to promote its use as a short supply chain resource in Italy and other Mediterranean countries. However, the durability of stone pine sapwood must be enhanced if outdoor use is to be considered. The impregnability of stone pine wood was studied following the standard EN 351-1:2008, using immersion, vacuum, and high-pressure methods with natural waxes and organic solvent-based and copper-amino-based preservative solutions. The efficacy of the impregnation was determined by calculating the kilos of preservative absorbed per cubic meter of wood and by measuring the penetration depth of the preservative. Thermal modifications were carried out using five different maximum temperatures, and their efficacy was determined by measuring the mass loss and color change. Subsequent to thermal treatments, the wood was exposed to a water-vapor-saturated atmosphere, and the increase in mass was calculated for different periods. Stone pine and Scots pine sapwoods showed similar response to the treatments with the exception of soaking impregnation methods where stone pine showed higher uptake, in particular when Silvanolin was used. Our investigation shows that stone pine can be a suitable short supply chain resource in Italy that, when impregnated, could be tested for outdoor use, exactly as is the case with Scots pine.

Spatial Solutions and Their Impacts When Reshuffling Coastal Management Priorities in Small Islands with Limited Diversification Opportunities

In small islands, the potential for new coastal activities and management options are often spatially limited. To reduce dependence on external factors and increase the resilience of populations to global changes and fluctuations in international markets, a recommended pathway is to diversify activities. We used a systematic prioritization tool with single and multiobjective zoning to explore the feasibility of scenarios at various levels of spatial diversification in the Gambier lagoon (French Polynesia), where black pearl culture is economically and spatially dominant. Local managers are committed to economic, livelihood, and environmental sustainability and agree that prioritizing both artisanal fisheries, which provide local food security, and ecosystem conservation should also be considered. Diversification options included the optimized reallocation of farming concessions and the identification of different types of conservation areas while taking into account traditional management areas. The scenarios were set to minimize surface areas and loss of access to existing fishing grounds. The solutions were compared between the scenarios with different cost metrics, allowing further discussions with stakeholders and managers. The Gambier case study shows that exploring diversification options in small islands using systematic prioritization tools can provide local managers with tailor-made plans adapted to island development questions.

COMMUNITY PERCEPTIONS OF LOCAL ECONOMIC DEVELOPMENT THROUGH TOURISM IN PORT ST JOHNS - SOUTH AFRICA

The purpose of this study was to investigate community perceptions of opportunities for local economic development (LED) in the town of Port St Johns (PSJ), using tourism as a conduit. PSJ is situated at the mouth of the Umzimvubu River along the Wild Coast region in the Eastern Cape of South Africa. A sample of 307 residents of PSJ responded to a questionnaire on the effects of tourism in their community. Overall, the findings reveal a tourism policy gap regarding the LED strategy and implementing a tourism development plan for PSJ. Therefore, the recommendation is to initiate a stakeholder consultative process, culminating in developing a strategic tourism plan for PSJ. This study contributes to the literature on including tourism in the general development plan of communities such as PSJ. At the same time, it provides strategic direction on how community livelihoods can be improved using the natural and cultural resources in PSJ.
