Abstract: In many developing African cities, municipalities' incapability to handle the growing amount of waste produced is becoming a worrisome concern. When solid waste management practices are outlined in terms of their sources, generation rate, transport capacity, transfer, and physical composition, they may be effective. The lack of timely information about waste generation, composition, environmental effectiveness, and community involvement in the solid waste management system in Freetown has been identified as a serious impediment to the long-term management of municipal solid waste practices. An evaluation of the difficulties of municipal solid waste management in the Freetown Western Area was conducted in this study by looking at environmental effectiveness and community participation. The Freetown Solid Waste Management (FSWM) was evaluated using a conceptual model of environmental effectiveness proposed by Kütting to see how ecologically efficient it is at ameliorating the horrible environmental impacts of solid waste. The study discovered that the current solid waste management system does not enhance environmental effectiveness and has a negative impact on the community. Inability to sufficiently separate waste at the source, and reduces the amount for final disposal implies a lack of community participation, environmental effectiveness, and institutional control of municipal solid waste handling. This analysis revealed that Freetown practices the least favoured option in the waste management hierarchy. That is, the first and best practice is to dispose of waste in waste dumps. The authors strongly recommend that the approach to these determinants focus on how solid waste is treated, rather than how waste is simply removed for final disposal.

Abstract: Climate change is expected to have significant environmental, economic, and social consequences for coastal farmers whose livelihood is dependent on nature. Agriculture is their main occupation and climate has a great impact on agriculture. As the economy of Bangladesh mainly hangs on agriculture so the impact is shown in the economy of this country. The factors that influence the adoption of climate-smart agriculture technology (improved stress-tolerant cultivars) in rice production in Bangladesh's Satkhira District were investigated in this study. Climate-Smart Agriculture refers to agricultural strategies that increase efficiency, improve resilience (adaptation), and reduce greenhouse gas emissions (mitigation). This study based on 100 rice-farming households from three villages in the sub-district of Tala Upazila in the coastal district of Satkhira, Bangladesh, an area likely to face increasing salinization due to relative sea-level rise, to determine the factors explaining which households were more likely to convert to salt-tolerant varieties of rice. This study found that higher levels of education, more farming experience, subsistence farming, access to credit and smaller family size were all significant predictors. The DAE, NGOs, policymakers, and government should keep attention to Education, Experience in farming, eating from own food and Family size, and Access to credit. It is possible to by increasing literacy and availability of information in the coastal area.

Abstract: The economic explosion accompanied by poorly controlled demographic growth that the city of Grand-Bassam has experienced over the past decade is threatening the preservation of the Ouladine Lagoon due to the direct discharge of large volumes of wastewater. This study aims to evaluate the level of organic pollution in the waters of the Ouladine lagoon. Eight stations spread over the entire lagoon were studied. This study is based on the exploitation of data from the water sampling campaigns carried out. The data were processed using the Organic Pollution Index (OPI) to determine the organic pollution of the water. Principal Component Analysis (PCA) was applied to the data to highlight the phenomena causing water pollution. The results obtained show that the lagoon waters have a high degree of organic pollution overall. This high organic pollution of the lagoon waters is mainly related to the BOD5 load and phosphate ions. The potential causes and threats of pollution in the lagoon are multiple and are closely related to intense human activity. They mainly come from domestic and agricultural wastewater discharges. This assessment highlighted the risk that untreated discharges pose to this aquatic ecosystem and the negative impact on the promotion of ecotourism in the area.
