“…The statistical analysis backs up the observation and demonstrates how La Pleasure Beach has been managed. This contrasts favorably with the survey conducted by Van Dyck et al (2016); Sakumono Beach had more trash than La Pleasure Beach.…”

“…This result is comparable to other surveys conducted on beaches in South Africa (STAP 2011b) and a few other carefully chosen European beaches (OSPAR 2007). The percentages of plastics found at the Sakumono and La Pleasure Beaches (66% by weight and 73% by number) also favorably contrast with those found by Van Dyck et al (2016). This supports the claim that, globally, plastics account for 60 to 80% of all marine litter collected (Derraik 2002;(2011a).…”

Abstract. Adjei O, Lamptey AM. 2021. Litter assessment at the Sakumono and La Pleasure coastal areas, Ghana. Indo Pac J Ocean Life 5: 83-91. Ghana has a difficult time managing waste, especially in the cities. The situation is even made worse in coastal urban areas by population growth. When the rains fall and wash the solid wastes downstream, most waste produced and lost inland ends up in the coastal and marine environment. In addition, revelers who use the areas for entertainment and tourism also contribute to the waste created. The Sakumono and La Pleasure Beaches in the Greater Accra Region served as the sites for this study. This study's primary goal was to assess how much waste was on the beaches at the two locations. The study made use of a transect measuring 1,000 m2. A total of 2,697 litter items were collected from the two beaches. During the survey, 50.07 kg from both sites comprised the entire weight of the litter collected. Comparatively, the amount of waste collected from La Pleasure was 18.28 kg, which accounted for 36.51% of the total amount of litter surveyed. The amount of trash collected from Sakumono Beach was 31.79 kg, representing 63.49% of the total litter surveyed. Plants were discovered to be the most prevalent material by weight and number. Plastics accounted for 72.56% of the total composition for both beaches, or 1,975 items, and 65.53% of the total composition, or 32.81 kg, respectively. In comparison to La Pleasure Beach, Sakumono Beach was found to be more littered. An alpha value of 0.05 (a p-value = 0.02) indicated this was significant. Ongoing monitoring, intensive education, and sensible policy initiatives are still essential to address the beach litter problem along Ghana's coasts.

Satellites collecting optical data offer a unique perspective from which to observe the problem of plastic litter in the marine environment, but few studies have successfully demonstrated their use for this purpose. For the first time, we show that patches of floating macroplastics are detectable in optical data acquired by the European Space Agency (ESA) Sentinel-2 satellites and, furthermore, are distinguishable from naturally occurring materials such as seaweed. We present case studies from four countries where suspected macroplastics were detected in Sentinel-2 Earth Observation data. Patches of materials on the ocean surface were highlighted using a novel Floating Debris Index (FDI) developed for the Sentinel-2 Multi-Spectral Instrument (MSI). In all cases, floating aggregations were detectable on sub-pixel scales, and appeared to be composed of a mix of seaweed, sea foam, and macroplastics. Building first steps toward a future monitoring system, we leveraged spectral shape to identify macroplastics, and a Naïve Bayes algorithm to classify mixed materials. Suspected plastics were successfully classified as plastics with an accuracy of 86%.

“…(2016) examined the effects of a smoking ban in Mexico and found that the ban was generally ineffective in reducing cigarette butt littering. A study in Ghana suggests that an already littered environment and the lack of authorities’ interest are the main reasons for increased littering (Van Dyck et al., 2016). Al‐Mosa et al.…”

Littering is a widespread problem that has negative consequences for the wellbeing of society and has been discussed in a wide range of subject areas. However, the lack of a unified understanding of the literature on littering presents an opportunity for a synthesis of the literature. This systematic review integrated the findings from 70 journal articles spanning 48 years. The articles were analysed for use of theories, models, methods, locations of study, variables and study findings. The researchers also undertook a content analysis of the literature to understand the evolution of approaches across time. The findings show that situational and psychological factors have often been studied using the ‘Focus Theory of Normative Conduct’ and the ‘Integrative Behaviour Model’. However, the findings have been inconsistent, with varying results for some of the situational, psychological and administrative factors. The content analysis identified that the literature from 1971 to 2006 was mostly confined to developed countries (80%) with the majority of studies examining situational and psychological factors. The gaps in the literature provided a basis for proposing five future research directions including the development of social marketing interventions by improving the theoretical groundings of previous works. As littering is consumer behaviour, it is also important to investigate the role of businesses as an integral part of the consumer exchange process to assist in improving the situation. The detailed future research directions and the conclusions of the review are presented.
