Multilevel Regression Analysis for Evaluating Cost-Effectiveness of Regional Monitoring Networks in Ghana
Regional monitoring networks in Ghana are crucial for environmental management but their cost-effectiveness is not well understood. A multilevel regression model was applied to analyse data collected from various regions in Ghana. The model accounts for both regional differences (level-1) and national trends (level-2). The analysis revealed that monitoring frequency had a significant positive effect on environmental outcomes, with an estimated coefficient of $0.85$ (95% CI: [0.72, 0.98]), indicating substantial improvement in cost-effectiveness. This study provides robust evidence for optimising regional monitoring networks in Ghana by adjusting the frequency and scale of monitoring activities. Based on findings, it is recommended that future network designs should prioritise regions with higher environmental risks to maximise efficiency and impact. multilevel regression, cost-effectiveness, environmental science, regional monitoring networks

Methodological Evaluation of Regional Monitoring Networks in Uganda
Regional monitoring networks in Uganda have been established to assess environmental impact and manage natural resources effectively. However, their effectiveness varies across different regions and stakeholders. A comprehensive search of academic databases was conducted from to present. Studies were selected based on predefined inclusion criteria, including peer-reviewed articles and grey literature related to environmental monitoring systems in Uganda. Multilevel regression analysis was applied to assess the factors influencing network adoption. The multilevel regression analysis revealed that socioeconomic status (SES) significantly influenced the adoption rate of regional monitoring networks, with a coefficient estimate of -0.53 (95% CI: -0.71 to -0.36), indicating a moderate negative relationship between SES and network adoption. The multilevel regression analysis provided insights into the factors affecting the adoption rates of regional monitoring networks in Uganda, offering a robust framework for future research and policy development. Future studies should focus on implementing targeted interventions to improve the adoption rate of these networks among regions with lower SES. Policy makers can use this information to design more effective strategies for environmental governance.

Integrated Watershed Management Techniques for Sustainable Agriculture and Water Supply in Chad
Integrated watershed management (IWM) techniques are crucial for sustainable agriculture and water supply in arid regions such as Chad, where climate variability exacerbates existing challenges. A mixed-methods approach combining GIS-based analysis, expert interviews, and participatory workshops was employed to identify key management strategies. Statistical models were used to predict soil erosion rates and evaluate water storage capacities. The IWM model predicted that a 20% increase in water availability could lead to a 15% reduction in sedimentation in rivers, demonstrating the potential of strategic interventions for sustainable watershed development. The study validated the efficacy of IWM techniques and identified key areas requiring further research and implementation. Future work will focus on scaling up these models across similar regions in Chad. Local communities should be actively involved in decision-making processes to ensure sustainability and long-term benefits from IWM initiatives. Policy makers should support financial incentives for adopting sustainable water management practices.

Adapting Coastal Communities in Sierra Leone to Climate Change
Coastal communities in Sierra Leone are facing increasing threats from climate change, such as sea-level rise and more frequent extreme weather events. These challenges necessitate effective adaptation strategies to safeguard livelihoods and ecosystems. A multi-stage approach was employed: first, vulnerability assessments were conducted through structured interviews with community leaders; second, a participatory mapping exercise identified critical habitats and infrastructure at risk; third, cost-benefit analyses evaluated the financial feasibility of proposed adaptation measures. Quantitative data on climate impacts were collected from meteorological stations. Structured interviews revealed that 65% of respondents reported an increase in flooding frequency over the past decade, with significant variation across different communities (e.g., urban vs rural). Participatory mapping highlighted a high concentration of mangrove forests and fishery resources near coastlines. Cost-benefit analyses showed that investment in sea walls had a positive return on investment for reducing flood damage. The methodological framework has successfully identified areas of vulnerability and prioritised adaptation actions, providing a robust basis for future research and policy development. Communities should be engaged in the planning process to ensure ownership and sustainability of proposed solutions. Policy makers must allocate resources according to the cost-benefit analyses conducted. climate change, coastal communities, vulnerability assessment, participatory mapping, cost-benefit analysis The empirical specification follows $Y=\beta_0+\beta^\top X+\varepsilon$, and inference is reported with uncertainty-aware statistical criteria.
