Specifically, we assessed the knowledge and perception of climate change, grassroot information flow on Greenhouse Gas (GHGs) and climate change, and local practices/activities taken towards mitigation/adaptation to climate change. \u0000Methodology:  The study involved both qualitative and quantitative research methods. Data was collected using literature reviews, questionnaires, focus group discussions, and key informant interviews.  Descriptive analysis was used to summarize data that were then presented as frequencies and percentages. Index construction was undertaken by summing up the scores for all statements relating to knowledge and perceptions to obtain a single group of variables. Chi-square tests were used to test relationship between variables.  \u0000Findings: Eighty (80%) of the respondents indicated that climate change is real, 69% of which attributed it to human activities, majorly (52%), clearance of vegetation. Most of the respondents (63%) had no idea about any climate change policy in the county while barely half (48%) could identify at least 1 greenhouse gas. This points to a gap in knowledge transmission from the national/County to the community and perhaps lack of sufficient community involvement in policy making. It was further established that there was a disconnect in information flow from scientific sources to communities that most respondents (63%) obtained climate information from community groups while only 2% relied on scientific sources, which would provide accurate information. this implies that the respondents may not be employing climate change mitigation strategies in their everyday interventions. Gender and education had significant influence on awareness and attitude towards climate change. \u0000Unique Contribution to Theory, Policy and Practice: These results suggest the need to shape community’s attitudes/perceptions about climate change by sharing accurate information through flexible channels and community involvement in formulation and implementation of climate change policies.","PeriodicalId":514551,"journal":{"name":"Journal of Environment","volume":"14 6","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141347515","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Towards Urban Forest Restoration in the City of Bukavu, Eastern Democratic Republic of Congo: Residents' Perceptions","authors":"L. Cirimwami, Fabrice Kibingani, C. Casinga","doi":"10.47941/je.1830","DOIUrl":"https://doi.org/10.47941/je.1830","url":null,"abstract":"Purpose: Demographic explosion is a common phenomenon in the Democratic Republic of Congo, especially in the city of Bukavu, where more than 1.6 million inhabitants live in 60 km², following the rural exodus due to insecurity in rural areas. This situation has led to deforestation, resulting in the destruction of most of the old green spaces, exposing the city to higher risks of flooding, erosion, landslides and loss of biodiversity, among other environmental problems. This study aims to understand the population's perception of deforestation in Bukavu, and to inform policy makers on how to restore urban forests. \u0000Methodology: To collect data for this study, we sampled and interviewed 210 informants, with 70 informants in each of the three communes of Bukavu: Kadutu, Ibanda and Bagira. \u0000Findings: The vast majority of informants are in favor of restoring green spaces (85%). At least 72.9% of them recognize that green spaces are important for air purification, environmental improvement, ornamentation, erosion control, biodiversity conservation and food production (in the case of fruit trees). They agree that the vegetation cover has decreased, especially since the 2000s, mainly due to the rural exodus and unregulated housing construction (81.9%). The population is aware that they are the main beneficiaries of green spaces (87.1% of informants) and accuse the government of being the main destroyer of green spaces and that it should be the main actor in their restoration. At the same time, residents recognize their share of responsibility for the destruction and restoration of urban green spaces, but consider it to be less than that of the government. In order to restore green spaces, they suggested tree planting initiatives (51.7%), with a preference for Eucalyptus sp., Cupressus lusitanica, ornamental and medicinal trees. Awareness raising and planned urbanization are among the strategies proposed to restore these spaces. \u0000A unique contribution to theory, practice and policy: The results of this study pave the way for a multidimensional understanding of climate adaptation, and demonstrate the need for a collective awakening of all stakeholders and the full mobilization of all actors in the quest to restore green spaces in the city of Bukavu for a healthier environment.","PeriodicalId":514551,"journal":{"name":"Journal of Environment","volume":"4 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140653946","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Employing Landsat imagery from 2000, 2011, and 2022, processed through ArcGIS 10.8 and TERRSET software, the study maps and quantifies urban expansion and land use changes.Methodology: The research concurrently leverages, microbiological techniques to assess air pollution, as well as water and soil contamination levels. Findings: The result highlighted an increase in built up area from 9.31% in 2000 to 17.45% in 2011 and 29.54% in 2022, which is evident particularly in Akure township area, correlating with a notable decline in environmental quality. Pollution hotspots, identified through rigorous spatial analysis, point to areas severely impacted by urban growth and high level of air pollution, as well as water and soil contamination. In addition, Land Use/Land Cover (LULC) prediction shows that built up area will likely cover about 30.09% by 2042. These findings underscore the urgent need for strategic urban planning and robust pollution control measures. Unique contributor to theory, policy and practice: The study advocates for a balanced approach to urban development, integrating environmental sustainability to mitigate the adverse effects of rapid urban growth. This research contributes to the broader discourse on urbanization's environmental impact, offering valuable insights for policymakers and urban planners in similarly developing regions of the world.","PeriodicalId":514551,"journal":{"name":"Journal of Environment","volume":"16 15","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139531107","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
