    Abstract Marine debris has been identified as a form of pollution for more than half a century, and it is a major concern for the general public due to its detrimental effects on the environment and human health. The accumulation of marine debris not only affects the aesthetic appeal of our oceans but also poses a significant threat to safety. The impact of marine debris on the tourism industry, especially the eco-tourism sector, is a growing concern both locally and globally. The objective of this study was to conduct a comprehensive assessment of marine debris on three beaches of Ghana along the Gulf of Guinea. It sought to survey the spatiotemporal changes in the concentration of marine debris, quantify the perceptions of locals and beach users of marine debris, examine the citizen science perspectives on marine debris and finally analyse the effects of marine debris on coastal resources. The study employed a shoreline debris survey and citizen science approach to achieve this objective. Content analysis in NVivo was deployed to analyze transcriptions from the interviews. A standing stock beach survey was used to survey debris in 100 m2 quadrants for 30 occasions each for the three studied beaches at 12-day intervals, which spanned one year. Debris was classified and quantified according to the NOAA classification scheme for marine debris. The quantitative data generated were analyzed in SPSS 23.0 to establish debris abundance and spatiotemporal differences. Results revealed that plastics are the dominant debris type, accounting for 52% of the total debris surveyed, which was confirmed by the citizen science approach. Biriwa Beach had a minor debris abundance, statistically different from Abandze and Anomabo. The paper found significant seasonal differences in the concentration and spatial distribution of all debris types except for plastics and processed lumber. Respondents acknowledged the effects of marine debris on humans and the environment. The study recommends making adequate waste management infrastructure ...

    Abstract Episodic floods, attributable primarily to climate change, global warming, and sea level rise, have worsened and continue to be a significant threat to life. Building resilience and improving the adaptive capacities of communities under threat will require institutional and cross-agency collaboration. This paper assessed institutional arrangements for mitigating and adapting to climate change-related flood risk in GAMA, Ghana. Using a descriptive cross-sectional survey, the study collected and analysed data from 65 private businesses and governmental, community, and civil society organisations to assess how institutions collaborate in preparing and adapting to flood risks in the study area. The study finds that frequent flooding, destruction of property and lives, and regular community agitations have triggered high-level consciousness, institutional arrangements, and collaboration within and among communities to build capacity and resilience. In addition, organisations have been educating indigenes on flood preparedness, providing relief items to support flood victims, and conducting training and research. Organisations have also supported communities in developing sandbags, planning sea defence mechanisms, providing rescue and evacuation assistance, providing transportation and logistics, and relocating stranded flood victims. Despite these efforts, the lack of adequate funding and logistics, coupled with the absence of proper consultation and involvement of most organisations in making national-level decisions on climate change and flood-related issues, have rendered flood management efforts less effective. This paper makes the case that proactive and collaborative flood responses should replace reactive and individual approaches to improve flood control efficacy and minimise casualties and property losses.

    Abstract This study presents an economic valuation of the groundwater resource in the Effutu Municipality. It tests the validity of the Gisser-Sanchez's position that the benefits derived from implementing a groundwater management intervention are insignificantly small compared to when no intervention is made. Hundred groundwater-user households were sampled by quota, convenience, and simple random sampling techniques. Assuming a quantitative approach, a contingent valuation-based willingness to pay questionnaire was used for data collection. Respondents were asked to value groundwater under two regimes based on quality: (1) unmanaged quality and (2) hypothetically-managed quality regimes. Using the Lancaster demand theory, the values assigned under either regime were assumed as the benefits users would derive from using groundwater. The statistical difference between the benefits of the two regimes was established by the Wilcoxon Signed Rank Test. The findings revealed that groundwater users are willing to pay 20 Pesewas (GH₵ 0.2) and 30 Pesewas (GH₵ 0.3), respectively, for a 10 L bucket of groundwater from the unmanaged quality regime and groundwater from the hypothetically-managed quality regime. The study established a statistically significant difference between the economic values of groundwater under either regime, indicating that the Gisser-Sanchez effect does not hold for groundwater used for drinking and domestic purposes in the Effutu Municipality. It has been expressed that improving groundwater quality will significantly increase the economic value of the resource. It has therefore been recommended that efforts should be made to treat groundwater to assume the quality of the Ghana Water Company's pipe-borne water after drilling projects in the Municipality.

    Abstract In light of Ghana's exploding population, rapid urbanization, and the imminent threat of climate change, urban flooding is a severe and increasing developmental concern. This study was conducted against the proposition that without anthropogenic factors, geophysical factors drive flooding within Accra Metropolitan Area. This study assessed spatial patterns of flood vulnerability using geophysical variables. The spatial analytical technique of weighted overlays was applied to ascertain the spatial variation of flood vulnerability. Based on geophysical variables, the study finds that only 71% of the metropolis is highly susceptible to flooding. Overlay of geophysical flood vulnerability map with residential neighbourhoods, the results correlated with known vulnerable areas. Three hazard level categories—high, medium, and low—have been established for the flood risk areas. Suburbs with a high or moderate risk of flooding necessitate more sophisticated engineering safeguards. The analysis also found that areas with medium and high incomes are becoming more vulnerable to flooding. The study proposes that efforts at flood control must focus on proper physical planning, stringent development control, elimination of drainage network flaws, and limiting the city's lateral expansion.

    Abstract Abstract The study examined the ecological health status of the Muni lagoon amidst increasing development in and around its catchment using a concentration of heavy metals in its water and fish samples as a proxy. Flame atomic absorption spectrophotometer (FAAS) laboratory analysis was employed to determine heavy metals (cadmium [Cd], lead [Pb], iron [Fe], manganese [Mn] and zinc) present in water and fish samples within the Muni Lagoon. The study revealed that the Muni Lagoon and feeder rivers were polluted with heavy metals (Fe = 0.453, Cd = 0.201, Mn = 0.105 and Pb = 0.024) comparing their concentrations with the US Environmental Protection Agency (USEPA) and Water Resources Commission (WRC) limit. Fish within the lagoon were found to pose no harm to consumers as traces of heavy metal concentrations were below the Food and Agriculture Organisation of the United Nations/World Health Organisation maximum permissible limit. The study further revealed that the application of agricultural inputs such as fertilisers, pesticides and domestic waste as well as unregulated gutter channels were the major source of heavy metals. A paired sample t‐test showed a statistically significant difference between the wet and dry season's concentrations of cadmium and lead. For cadmium, the t‐test found t(5) = −7.265; p = .001 between the wet season's concentration and the dry season's concentration and for lead, the t‐test found t(5) = 5.061, p = .004 between the wet and dry season concentrations in the lagoon. It is therefore recommended that the Forestry Commission, Municipal Assembly and the local leaders should collaborate in regulating activities occurring in and around the catchment of the lagoon.

    Abstract Abstract The study's overarching goal was to examine the dynamics of geomorphological interaction and their effects on the urban expansion of the Weija-Gbawe Municipality in Ghana's Greater Accra Region. The study deployed a quantitative research approach to achieve the objective. A descriptive research design was used in collecting and analyzing data from three hundred and fifty-one (351) participants with a closed-ended questionnaire. The study employed a cluster sampling technique to select the participants based on areas with high concentrations of built-ups and other areas with low concentrations. Using the important relative index (RII), the fundamental level is ranked by the index. SPSS version 26 was used to analyse the data, and the results are shown in a descriptive frequency distribution table. The findings revealed population growth in the Weija-Gbawe Municipality as the main human factor transforming the landscapes' geomorphology, as residents change the landscape for human occupation and industrial uses. Similarly, the topographical terrain, emphasizing slope and elevation were the predominant geomorphological characteristic modifying urban expansion in the Municipality, as settlements were mainly distributed on flat terrain, and the elevation and slope were significant constraints for expansion of the city. Furthermore, urban land utilization in the Weija Gbawe Municipality is distinguished by an industrialized economy and built-up facilities. The paper concludes that applying geographic information systems, remote sensing, and field surveys is essential for generating comprehensive knowledge of urban and anthropocene geomorphology; this is possible through the use of GIS and remote sensing in analyzing the land use land cover changes in the study area. The study suggests enacting, enforcing environmental by-laws, intensifying, and restructuring environmental education by various stakeholders, including the Environmental Protection Agency (EPA) and the Municipality's Physical Planning Agency ...

    Abstract Challenges faced by African countries in achieving the goals of sustainable development are similar and transboundary. Previous analysis of Africa’s progress on the Sustainable Development Goals (SDGs) has largely been non-spatial, reducing the ability to find spatial relationships between countries and SDGs to help cooperation and proffer country-specific interventions. This study adopted techniques of exploratory and inferential spatial statistics to assess the successes of African countries from 2016 to 2020 in achieving the goals of sustainable development. Also, the study sought to understand how the spatial synergies and trade-offs between SDGs vary per country and time. The results revealed that spatial hotspots of countries with high SDGs scores were mostly confined to northern African countries with significant coldspots within central and eastern Africa and few patches in western and southern Africa for 2016. In 2020, the number of countries forming hotspots reduced, with Central African countries as significant cold spots. Five main spatial relationships: positive linear, negative linear, concave, convex and undefined complex, were found among countries and the SDGs. However, these spatial relationships were fluid as they changed over time and with different levels of influence from 2016 to 2020. The study concludes that generic solutions and policies by development agencies, governments, development finance instiutions and other impact investors will not be enough in achieving the SDGs because of the spatial heterogeneity of the continent. Tailored and country-specific policies based on results of spatial statistics matter.
