Impact of Community-Led Total Sanitation Programmes on Gender Norms in West African Cities
Community-led total sanitation (CLTS) programmes have been implemented in West African cities to improve access to basic sanitation facilities and reduce health risks. However, their impact on gender norms remains understudied. The analysis employs quantitative methods and synthesizes findings from existing studies that include both qualitative and quantitative data. The meta-analysis uses standardised summary statistics and robust standard errors to account for variability across studies. Findings suggest a significant positive correlation between the implementation of CLTS programmes and changes in gender norms, with a proportion of households reporting improvements in attitudes towards women's participation in sanitation-related decisions increasing by around 30% compared to baseline levels. While the findings indicate potential benefits for gender empowerment through CLTS programmes, further research is needed to explore these effects in diverse contexts and over longer periods. Future studies should consider longitudinal data collection and include more detailed qualitative assessments to better understand the mechanisms underlying observed changes in gender norms. The empirical specification follows $Y=\beta_0+\beta^\top X+\varepsilon$, and inference is reported with uncertainty-aware statistical criteria.
Methodological Foundations for Evaluating Yield Improvement in Smallholder Farm Systems Using Difference-in-Differences Analysis in Rwanda

Remote Sensing and GIS for Environmental Monitoring in Ethiopia
Remote sensing and geographic information systems (GIS) have been increasingly utilised for environmental monitoring in various regions around the world. The study employed high-resolution satellite images from multiple sources, including Landsat and Sentinel missions, to monitor land cover changes over time. These images were processed using standard remote sensing techniques such as image classification and spectral analysis. The spatial data was then integrated into a GIS platform where layers of environmental variables (e.g., vegetation types, water bodies) were overlaid for detailed mapping. The findings reveal that the integration of satellite imagery with GIS significantly improved the detection of land cover changes, especially in areas previously obscured by cloud cover. A notable proportion—approximately 85%—of newly detected changes could not be identified using traditional field surveys alone. This study demonstrates the utility of remote sensing and GIS for environmental monitoring, particularly in regions with limited ground data coverage. The results suggest that continuous satellite monitoring should be complemented by periodic on-ground verification to ensure accuracy. Additionally, further research into cost-effective sensor systems is recommended to extend this approach to more resource-constrained areas.
