This study investigated the presence and distribution of macrolitter along four beach sites on the Ferrara coast, North-eastern Italy. At each site, monitoring campaigns were conducted from summer 2023 to summer 2024 to assess seasonal and cross-shore fluctuations of litter items and their relations with local geomorphological features. Following the Marine Strategy Framework Directive, 5627 litter items were collected, with an average density of 0.61 ± 0.23 items/m². Plastic was the dominant material, representing 94% of the total. The Clean Coast Index (CCI) was applied to evaluate beach cleanliness, seasonal patterns, and cross-shore litter distribution. Although the sites were generally classified as “Clean”, CCI values revealed a progressive decline in cleanliness from summer to spring. Litter was especially accumulated in the upper backshore and at the dune foot. All macrolitter items were classified by material, typology, and usage category to identify potential sources of release, following the Joint List of Litter Categories for Marine Macrolitter Monitoring. The “Top 10” of the most collected items was compiled per each site, season, and geomorphological zone. The results underscore the relevance of high-resolution monitoring programs to support the development of targeted management strategies for effective beach litter mitigation. Full article

Marine litter is a critical environmental issue, with beach litter being its most visible indicator. Despite severe pollution on Mediterranean beaches, Tunisia currently lacks a national beach litter monitoring program. To address this gap and support the development of such a program, particularly at pollution hotspots like urban beaches, we conducted a one-year study on six Tunisian beaches. We employed an innovative, accelerated multiple 10 m transect method tailored to highly polluted beaches, focusing on macro-litter (>2.5 cm). This method significantly reduces survey time compared to the standard 100 m approach while maintaining comparable pollution metrics, offering a practical and efficient solution for areas with high litter density. Our findings reveal an average litter density of 1.01 ± 1.08 pieces/m², with higher pollution in urban areas. Based on the Clean Coast Index (CCI), two beaches were classified as extremely dirty, one as dirty, two as moderately clean, and one as clean. Plastics (59.2%) and cigarette butts (21.1%) were the most prevalent pollutants, with single-use plastics comprising 52.5% ± 5.3% of total litter. Most of the litter (60.6%) originated from shoreline activities and poor waste management. These findings underscore the urgent need for a long-term national beach litter monitoring program. The integration of our accelerated transect method would enable efficient, effective surveys on highly polluted beaches, providing critical data to address litter sources and support targeted strategies for mitigating pollution and protecting Tunisia’s coastal ecosystems.

This paper deals with beach litter presence on the Ionian coast of Albania, i.e., at Vlora Bay and the Albanian Riviera, which is the most famous coastal tourist destination in the country. Along 16 beaches surveyed in November–December 2022 was found a total amount of 6621 litter items (or 416 kg) belonging to 114 categories of the EU J−code list. Most of these were plastic fragments and items (82%), mainly linked to local tourist activities. Wastewaters were responsible for bringing different litter items to the urban beaches of Vlora Bay. The most commonly observed litter items were cigarette butts, plastic caps/lids, and medium-sized plastic fragments of non-foamed plastic. The cleanest beaches, quite often, were the ones where beach clubs implemented clean-up programs during and at the end of the summer season. The results of this paper constitute a baseline of the beach litter amount and content along the study coast, which has never been investigated before. Municipalities and beach clubs have to implement more frequent and efficient clean-up activities and educational initiatives to reduce beach pollution, with special attention paid to the presence of cigarette butts and other small plastic items.

Litter abundance and typology were investigated at different beaches and mangrove forests at nine sites on the Colombian Caribbean and Pacific coasts. Average litter abundance on the Caribbean Sea beaches (1.42 items/m²–12.21 g/m²) and in mangrove forests (1.29 items/m²–28.72 g/m²) were greater than that of the Pacific Ocean beaches (0 items/m²–0 g/m²) and mangrove forests (1.13 items/m²–79.41 g/m²). The most abundant litter material was plastic, which represented 93.61% of the total litter content. According to the Clean Coast Index, the sites analyzed in the Caribbean Sea were “Moderate” to “Extremely Dirty”, while those in the Pacific Ocean were “Clean” to “Moderate Dirty”. The Magdalena River is considered the main source of litter on the Caribbean Sea coast, while on the Pacific Ocean coast, litter is essentially associated with the mismanagement of solid wastes. This study constitutes a baseline on the litter content of beaches and mangrove forests, and is useful for establishing sound strategies for their protection, restoration and conservation.

Plastic pollution in the ocean is an emerging environmental concern in the Philippines. This study was conducted to investigate the prevalence of macroplastics, composition of plastic litter, and the clean-coast index (CCI) of urban and rural beaches in Sarangani Bay. Plastic litter was collected by delineating a 100-m transecting line with three 4 m × 4 m quadrats. The density of macroplastic litter in urban areas (0.66 items m⁻²) was significantly higher than in rural areas (0.29 items m⁻²). The plastics sampled were predominantly food packaging, such as polyethylene bags, which are locally known as sando bags. The accumulation rate of macroplastic litter ranged from 0.07 items d⁻¹ m⁻² to 0.40 items d⁻¹ m⁻², in which urban beaches (0.25 items d⁻¹ m⁻²) have a significantly higher accumulation rate than rural beaches (0.11 items d⁻¹ m⁻²). Overall, the calculated CCI of the beaches of Sarangani Bay was categorized as clean to moderately clean for rural beaches and moderately clean to extremely dirty for urban beaches. Full article

Twelve beaches located in Ceuta (Spain) were studied from February to April 2019 to assess litter amounts (expressed as number of items), categories and temporal distribution. At each beach, three surveys were conducted, i.e., one per month (i.e., 36 in total). Selected beaches covered urban (7), rural (2) and remote (3) bathing areas. Plastic represented the dominant material, i.e., 35.2% of all debris, followed by glass (18.2%), pottery/ceramics (14.6%), wood (11.4%), metal (11.4%), paper/cardboard (4.8%), cloth (3.5%), rubber (0.7%), organic (0.3%) and other materials (0.1%). The Clean Coast Index was calculated to classify beaches in five categories for evaluating the cleanliness level of the coast observed at each survey: “Very Clean” (7 surveys), “Clean” (10), “Moderately Dirty” (8), “Dirty” (2) and “Extremely Dirty” (9). Litter occurrence was assessed by the Litter Grade methodology, which allowed to classify beaches in four grades: “A”: very good (0); “B”: good (4); “C”: fair (7); and “D”: poor (25). In a few surveys, some beaches were considered “good”, but their management should not be ignored because in other surveys those beaches reached fair and poor scores. Several potentially harmful litter items were related to beach users. Severe eastern storms removed litter at many of the beaches investigated and favored accumulation at others. Data analysis shows significant differences in litter abundance with respect to site, beach typology and the presence of cleaning operations but no important differences between the studied months. Rural beaches recorded the most litter, followed by urban and remote beaches. All beaches require immediate and more appropriate management actions to improve their environmental status.

Tourism activities are considered, among others, the backbone of the local economies. However, tourism activities lead to adverse environmental impacts, especially in coastal zones. Coastal areas are considered and recognized as of strategic importance due to the fact that several activities take place, from leisure to business. At the same time, coastal areas are under pressure from tourist activities, and the waste generated is a very serious issue. Therefore, there are limited studies related to the environmental dimensions of the COVID-19 pandemic in the coastal environment. This paper provides answers to the hypothesis that the pandemic lockdown scenario would improve environmental performance due to reduced usage and, therefore, waste, taking into account specific key performance indicators (KPIs) as these KPIs are used to evaluate the performance of an area. The results showed that the study area improved, as did the selected KPIs, i.e., clean coast index (CCI), waste accumulation rate (WAR), and waste accumulation index (WAI). Additionally, according to the final results, the concentration of micro-, meso- and macroplastics on the beach reduced, and the main issues remained the solutions on cigarette butts, straws, and other plastic containers. Furthermore, the final results are considered very useful to local authorities, stakeholders, consultants, policymakers, and any other competent authorities, to reschedule their waste management strategies, to improve waste infrastructures and their level of services (LOS), as well as, to suggest frequent awareness-raising activities to their visitors on how to protect the coastal environment, taking into account a pandemic scenario, as well as, the policy alternative impacts on EU coastal zones 2000–2050.
