Micro plastic: an imperceptible threat on Agua Dulce Beach, Chorrillos District

The use of plastics in the world is increasing, but their proper final arrangement is limited. Peru made regulatory efforts to reduce its use;however, they are isolated activities that have not represented a significant change in their management. This study allows to identify the presence of microplastic on one of the busiest beaches of the city of Lima Metropolitana, during the emergency period caused by the SARS-COV-2 pandemic. To achieve the objectives of the research, it has been sampled in high tide and supra-coastal areas, applying the methodology proposed in the Ministry of the Environment's Soil Sampling Guide. This study shows the presence of microplastics, with an abundance of 43 pieces per m2, and found that the predominance of the type of microplastic found is of secondary origin (polystyrene and polypropylene);however, 20.9% correspond to primary microplastics (pellets) whose source could not be determined. Finally, it is indicated that despite restrictions on the state of emergency the number of microplastics per m2 in Agua Dulce Beach between 2019 (40 pieces) and 2020 (43 pieces) increased by 7.5%.

What is hidden in the luggage? First assessments of illegal seashells gathering in Sardinia (Italy)

Natural souvenirs collection has been identified as a driving force in biodiversity and habitat degradation of tropical marine ecosystems. This work considers this phenomenon in the Mediterranean region taking Sardinia (Italy), one of the most renowned tourism destinations, as a case study. The biological material seized at Cagliari-Elmas Airport (years 2019–2020: 138 kg) was analyzed: 199 taxa were identified, gastropods (112 species, 7866 pieces) and bivalves (63 species, 34,218 pieces) resulted the most represented classes. Twenty-two protected species were found in the tourists' luggage including Patella ferruginea and Pinna nobilis, the invertebrates most threatened with extinction in the Mediterranean Sea. This study demonstrates that the illegal collection of natural mementos is common in Sardinia, thus its relevance is not limited to tropical regions. Regulation, enforcement and compliance shortcomings emerged, highlighting the importance of strengthening stakeholders' collaboration for a deeper insight on this phenomenon and implementing effective conservation strategies.

Impact of Disruption on Ship Emissions in Port: Case of Pandemic in Long Beach

To achieve environmental sustainability on ships, stakeholders should make efforts to reduce emissions. Port authorities are crucial to attain this goal by introducing new policies. This study takes the Port of Long Beach as an example to assess port-wide ship emissions and explain the significance of shore power policy. Additionally, the study considers the impact of disruptions, such as the COVID pandemic, on ship emissions. The analysis compares data from three years before and after the pandemic to examine the relationship between ship waiting times, quantities, and emissions. The findings indicate that the majority of port-wide ship emissions are generated by berthing or anchoring vessels, from ship auxiliary engines and boilers. Furthermore, ship congestion due to reduced port productivity during the pandemic significantly increased emissions from berthing and anchoring vessels, with the emission proportion increasing from 68% to 86%. Adopting the shore power policy has effectively reduced ship emissions in port areas, and increasing the number of ships utilising shore power will be instrumental in tackling excessive ship emissions.

Community-based disaster risk reduction efforts in facing the threat of abrasion disasters at Bungin Beach, Bekasi Regency during the covid-19 pandemic

Abrasion causes coastal areas to have a very high level of dynamics and often has an impact on environmental damage, so it needs to be anticipated. In the last 2 years, the whole world has faced a crisis caused by the pandemic due to Corona Virus Disease (Covid-19). During the pandemic, the environment where coastal communities live is still threatened with abrasion. Some mangrove planting and rehabilitation activities had to be stopped to suppress the spread of the virus. The purpose of this study was to identify the role of community groups (Tourism Awareness Group) as a key factor in overcoming abrasion events during the Covid-19 pandemic at Bungin Beach. Interviews and direct observations were conducted to obtain survey data. Additional analyzes were then carried out through relevant journals and literature reviews. As a result, from 1997 to 2021 there has been abrasion on Bungin beach. The Tourism Awareness Group plays a role in post-pandemic recovery, especially in the economic sector. Through mangrove planting activities, not only to restore the economy of coastal communities during the pandemic but also to protect coastal ecosystems from the threat of abrasion on Bungin Beach.

COVID-19 personal protective equipment (PPE) contamination in coastal areas of Granada, Spain.

The use of disposable personal protective equipment (PPE) as a control measure to avoid transmission against COVID-19 has generated a challenge to the waste management and enhances plastic pollution in the environment. The research aims to monitor the presence of PPE waste and other plastic debris, in a time interval where the use of face mask at specific places was still mandatory, on the coastal areas of Granada (Spain) which belongs to the Mediterranean Sea. Four beaches called La Rijana, La Charca, La Rábita and Calahonda were examined during different periods. The total amount of sampled waste was 17,558 plastic units. The abundance, characteristics and distribution of PPE and other plastic debris were determined. Results showed that the observed amount of total plastic debris were between 2.531·10-2 and 24.487·10-2 units per square meter, and up to 0.136·10-2 for PPE debris, where face masks represented the 92.22 % of the total PPE debris, being these results comparable to previous studies in other coastal areas in the world. On the other hand, total plastic debris densities were in the range from 2.457·10-2 to 92.219·10-2 g/m2 and densities were up to 0.732·10-2 for PPE debris. PPE debris supposed 0.79 % of the weight of total waste and the 0.51 % of total items. Concerning non-PPE plastic waste: cigarettes filters, food containers and styrofoam were the most abundant items (42.95, 10.19 and 16.37 % of total items, respectively). During vacation periods, total plastic debris amount increased 92.19 % compared to non-vacation periods. Regarding type of beaches, the presence of plastic debris was significantly higher on touristic/recreational than in fishing beaches. Data showed no significant differences between accessible and no-accessible beaches, but between periods with restrictive policy about mask face use and periods with non-restrictive policy data suggest significant differences between densities (g/m2) for PPE litter. The amount of PPEs debris is also correlated with the number of cigarettes filters (Person's r = 0.650), food containers (r = 0.782) and other debris (r = 0.63). Finally, although interesting results were provided in this study, further research is required to better understand the consequences of this type of pollution and to provide viable solutions to this problem.

COVID-19, mobility, leisure, and travel around the world

The paper uses daily data from Google to analyze the impact of the COVID-19 pandemic on people's mobility around the world regarding three types of leisure and travel activity: retail shopping and recreation;participation in open spaces, such as parks, beaches, gardens, and marinas;and food and medicine. These types of activity reflect important leisure and travel choices of people under conditions of epidemiological risk. We use the daily mortality rate as a key predictor. The results show that higher rates of mortality are associated with a lower mobility in shopping and recreation activities, higher mobility in open space activities, and rather insignificant changes in mobility regarding necessities. The effect depends on the stringency of the lockdown policies. The results remain robust after applying endogeneity analysis and country-level controls.

Facemask: Protection or threat?

Facemasks were widely used as a protection against SARS-COV-2, which significantly reduced COVID-19 transmission during the pandemic. However, concerns have been raised regarding its adverse impacts on human health due to intense use and mismanagement. Although rampant plastic littering was the norm before the pandemic, the magnitude of the problem is worsening as potentially COVID-19-infected facemasks are thrown along the shoreline. This study assessed the discarded facemasks on the most popular beach destinations in Mati City, Davao Oriental, Philippines. A total of N = 284 discarded facemasks were found in a cumulative area of 22,500 m2, with an average density of 8.4 × 10-4 items/m2. The surgical facemask (82 %; n = 234) was the most abundant type of facemask found in the areas, followed by KF94 (16 %; n = 45) and KN95 (2 %; n = 5). The Analysis of Variance (ANOVA) showed significant differences in the visual counts of facemasks on the three beaches (p < 0.05).

The beach is closed, but not to us: pandemic experience and social boundaries in rural Okinawa. (Special Issue: Hybrid beliefs and identities.)

This article offers an anthropological and ethnographic perspective on how the COVID-19 pandemic affected and shaped rural community social behaviour in Kayo village during Japan's first official state of emergency, April 7th to May 6th, 2020. It draws from observations and informal conversations with villagers during this period. First, it discusses the researcher's experience of living in a rural village in northern Okinawa during the state of emergency and addresses the position of the ethnographer during the pandemic. It explores the Japanese concept of uchi/soto (inside/outside), to discuss the insider/outsider dynamics that characteriseeveryday social life in Okinawa. Secondly, it engages with Marshall Sahlins's (2013) idea of kinship as 'social mutuality' to consider how the pandemic invites us to rethink interpersonal relationships, space negotiation, and social boundaries, and how the latter are reconstructed and negotiated according to the new situation (emergency state). The example of Okinawa rural communities shows how rural populations can reconceptualise their environment and practices during the pandemic. It allows us to understand how notions of space, accessibility and kinship are reshaped into subtle boundaries between locals and outsiders in order toregulate access.

Tourism in the COVID-19 context in mesotidal beaches: Carrying capacity for the 2020/2021 summer season in Pehuén Co, Argentina.

As a result of the COVID-19 pandemic, there is an evident decrease in economic activity, especially in the tourism sector. On the southwest coast of the Buenos Aires Province (Argentina), coastal cities base their economy on 3S tourism. In this context, the analysis of social views is crucial for participatory coastal management. As well as the forecast of beach use areas in semi-diurnal mesotidal and low-slope beach conditions, wherein few hours the available beach can double or disappear. Therefore, our objective was to determine the beach's optimal use according to its tides, socio-environmental characteristics, and the perception of the interested parties about the 2020/2021 summer season in the pandemic context in Pehuén Co Beach. We employed camera images (January 2019 and 2020) to obtain the behaviour of normal, spring and neap tides, beach geomorphology, and daily and hourly beach use curves. Online surveys were also conducted with residents, second homeowners, and Pehuén Co visitors about their perception for the 2020/2021 summer season. With this analysis, we were able to divide the beach into four areas according to its potential carrying capacity. During low tide, users' maximum capacity on the beach, respecting sanitary distances, may be 6400 people. Meanwhile, at low tide, this number may rise to 34,000. This information is essential for coastal management after the COVID-19 irruption to ensure maximum efficiency in using the beach maintaining a safe social distance.

Impact of COVID-19 pandemic on beach tourism on India

COVID-19 Pandemic has a profound Impact on the Indian tourism sector, especially on beach tourism. Research shows significant changes in the pattern of the ecological terrain of coastal areas and on the community dependent on tourism business and marine life, due to the imposition of lockdown for several months. The paper discusses the change in behavioral patterns of people during Pre and Post COVID-19 for visiting any beach destination in near future in terms of preferences in accommodation, selection of beaches based on crowd and other factors that will be considered in post pandemic days. This study brings out various key indicators shaping the pattern of beach holidays in the future based on the survey conducted among tourists belonging to youth population. The survey considered the tourists preferences of visits and factors they would look upon to choose beach holidaying in the Post COVID-19 years. The influence of the pandemic on quality of beaches, visitors' willingness to visit beaches in future, Post Pandemic opportunities and strategies of destinations for shaping tourism further have also been examined.

Occurrence of emerging contaminants in surface water bodies of a coastal province in Ecuador and possible influence of tourism decline caused by COVID-19 lockdown.

Emerging contaminants in water bodies is an issue of concern due to their impact on the ecosystem and human health. The COVID-19 pandemic has forced the implementation of protective measures such as social distancing, lockdowns, and remote work, which have affected the tourism influx. This study aimed to evaluate the occurrence of emerging pollutants in bodies of water in Esmeraldas, a coastal province of Ecuador, before and during the COVID-19 pandemic in a highly touristic region. For this purpose, surface waters from 14 beaches and ten river mouths were sampled at two-time points in November 2019 and November 2020. Compounds widely consumed in Ecuador: acetaminophen, caffeine, sodium diclofenac, trimethoprim, and sulfamethoxazole were extracted from water samples by solid phase extraction SPE and detected with a UPLC-QTOF-MS system. We found a decrease in the occurrence of caffeine from 100 % to 4.2 % of caffeine and 25 % to 0 % of diclofenac, likely related to the decline in tourist afflux due to the lockdown measures. Most of the compounds diminished in terms of frequency and/or concentration; however, as COVID-19 treatments make use of different pharmaceutical compounds such as antivirals, antibiotics, antiparasitics, or glucocorticoids, future studies should include these to assess their environmental impact.

A Sea Level Rise Resilient Design for the Royal Hawaiian Groin, Waikiki, Hawaii

The Royal Hawaiian groin is located on Waikiki Beach, Hawaii, and anchors 1,730 linear ft (527 m) of critical beach in the heart of Waikiki. The groin was originally constructed in 1927, and by 2012 was in very obvious need of replacement. Rock rubble mound breakwater and groin construction has been traditionally used in Hawaii, and is aesthetically the desired construction methodology for coastal structures. Oceanographic design parameters were based on a potential direct hurricane strike and likely future sea level rise. The groin design is a hybrid structure;the base is composed of armor stone, and the crest is made of cast-in-place fiber-reinforced concrete. The groin is also adaptable to sea level rise by permitting a relatively easy increase in the concrete crest cap elevation without the need for heavy equipment to dismantle and reconstruct the groin. Construction in normally densely crowded Waikiki was going to be difficult;however, when construction started in May 2020 Hawaii was in COVID-19 lockdown, the hotels were closed, and Waikiki was empty, with no one to be impacted by closed beach access or construction noise. © 2022 by the American Society of Civil Engineers.

Has the "Covid-19" lockdown an impact on beach faunal communities? The central Atlantic coast of Morocco as a case study.

The restrictions related to the COVID-19 pandemic have led to a global hiatus in anthropogenic activities; several scientists have utilized this unique opportunity to assess the human impact on biological systems. In this study, the study describes for a period of five years (2018-2022) how the faunal community have been affected by human disturbances, as well as the effect of the "anthropause" period driven by the COVID-19 lockdown. The results confirmed human disturbances on faunal communities related to coastal urbanization. It was found that the "anthropause" period showed the highest values of abundance and biomass, hence the "COVID-19 lockdown" allowed recovery of faunal communities. The findings highlight the impact of human disturbances and that the community showed resilience. Overall, the authorities must perform restrictive measures aiming to mitigate the impact of anthropogenic activities in the study area including the banning of off-road and recreational vehicles, carrying out efficient cleaning and grooming operations, monitoring the severe harvesting of edible species, as well as penalizing the disposal of anthropogenic waste and sewage discharge from the touristic facilities. Likewise, management actions such as the temporal beach closures and the regular surveillance could be advantageous to provide a more sustainable exploitation of sandy beaches.

Upgrading Island Tourism Value from the Perspective of the Tourist Experience—A Case Study of Tianheng Island, China

Although island tourism is vital to the economy of developing countries, many islands with great potential for tourism development do not plan for it adequately. The objective of this paper is to establish an island tourism value mining and promotion model from the tourist perspective by selecting the status value indicators of basic conditions, vacation tourism resources, and sightseeing tourism resources, as well as the promotion indicators of five types of recreational fisheries, including beach activities, recreational fishing, marine sports, rock climbing, and sightseeing platforms. Then, we evaluate the whole island and develop suitable areas by using an analytic hierarchy process. This study took Tianheng Island as an example and divided the study area into grids and land use types. The results indicate that the basic conditions and tourism resources of Tianheng Island are in a general level, and the vacation tourism resources are in high quality, while there is further room to improve them. We identified that the island has four areas which are suitable for scenic development, two sandy beaches, two recreation fishing areas, one marine sports area, and one island rock climbing area. Our findings are consistent with the actual situation in Tianheng Island, demonstrating that the model is practical and can provide an essential reference for the scientific protection and utilization of island tourism resources.

Hospital superbug traced to remote island beach

Anuradha Chowdhary, professor of mycology, Vallabhbhai Patel Chest Institute, University of Delhi, and corresponding author of the study, says that while C. auris isolates found on the beach were multidrug-resistant, those found in the remoter salt marshes of the Andaman islands were not resistant to ordinary anti-fungal drugs. “Thorough screening of patients and their environment is required as also cohorting (putting together) of patients who are colonised by C. auris —since they continuously shed viable yeast cells from their skin and contaminate hospital environments.” The present study notes that a hypothesis published July 2019 in mBiosuggests that C. auris might be native to wetlands and that its emergence as a human pathogen may be linked to the effects of global warming effects on wetlands.

Distribution of marine debris during COVID-19 pandemic at apristineisland on the Andaman Sea, Thailand

The study was conducted with an exploratory study design to explore the amount of debris around beaches on Libong Island, Thailand. Libong Island is one of the significant tourist attractions in Trang Province. The study was conducted by collecting samples from 4 areas during February, June, September and December 2020. The findings from the study showed that 1,580 items of debris were found with a total weight of 44,744 g. The most common debris found included hard plastic glass, fabric, and fibre, respectively. Thung Ya Kha Beach was the beach where the highest amount of debris was found. The largest quantity of debris (692 items) was found in June, followed by 404 items in February, 274 items in September, and 210 items in December. Based on this study, the outstanding debris was comprised of plastic, including 87 types of plastic, both hard and soft varieties, totaling 805 items. No COVID-19 related products were found on the beach, possibly due to a government emergency declaration. Regarding the closure of beaches and the country's lockdown, there were few Thai tourists. There were no foreign tourists in June or September. The result of the waste separation that the major activity causing waste was shoreline and recreation activity.

Multitemporal Scenic Evaluation of Urban Coastal Sites: A Peruvian Case Study

Along the coast of Peru, intensive urbanization and tourism development were related to coastal scenery deterioration. This investigation carried out a scenery evaluation of 20 urban beaches from the “Circuito de Playas de la Costa Verde” (CPCV), a key beach corridor in Lima (Peru). For this purpose, the Coastal Scenic Evaluation System (CSES) was applied in three different seasons, using fuzzy logic to reduce observer subjectivity and estimate the Evaluation index (D). A total of 26 parameters were evaluated to estimate the D value during summer 2020, winter 2020, and summer 2021, to determine the temporal variability of the landscape of an urban coastal sector, such as the CPCV. The results show that all evaluated beaches are classified as very unattractive sites (Class V). Additionally, no significant differences were found between seasons but between beaches. Litter and disturbance factors (noise) were the main human parameters that had low and variable scores during assessments and influenced the D index value estimate. This scenery assessment proposes further implementations of new beach management strategies and actions focusing on landscaping and conserving coastal ecosystems. Strengthening monitoring to reduce noise and litter disturbance and promoting environmentally friendly coastal usage are vital aspects that must be implemented.

Analyzing the impact of the covid epidemic on beach access traffic

The covid 19 epidemic has been marking the pace of life around the world for the last two years, and it left clear marks on economic activity, our social life and even the pollution associated with human activity. One of the consequences is related to the decrease in car traffic, especially in the months of mandatory social confinement. This work analyzes the impact of the epidemic on traffic regarding access to the beaches of Barra and Costa Nova in the region of Aveiro, Portugal, through the infrastructure of the PASMO project. Therefore, the weekly and weekend traffic profiles evolution were analyzed over the various months of 2020. The work also compared the evolution of infections with the evolution of road traffic, as well as the impact of the various events related to the epidemic in road traffic. © 2022 IEEE Computer Society.

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.
