Mitigating Greenhouse Gas Emissions Among Smallholder Farmers in Rwanda
Rwanda's smallholder farmers contribute significantly to greenhouse gas (GHG) emissions, particularly in the Southern Highlands region due to intensive agricultural practices and wood fuel use for cooking. Climate change mitigation efforts are crucial but require robust methodologies to assess their impact. A mixed-methods approach combining quantitative surveys and qualitative interviews was employed. A linear regression model with robust standard errors is used to estimate the impact of interventions on GHG emissions, accounting for farmer characteristics and contextual factors as control variables. Farmers reported a reduction in wood fuel consumption by an average of 15% over two years, leading to a decrease in CO2 equivalent emissions by approximately 3.5 tonnes per farm (n=100). The study confirms the potential of agricultural policies to mitigate GHG emissions among smallholder farmers. Further research should explore longer-term impacts and scalability across different agro-ecological zones in Rwanda.

Methodological Evaluation of Municipal Water Systems in Uganda Using Difference-in-Differences for Cost-Efficiency Assessment
Uganda’s municipal water systems are critical for public health and economic development. However, their cost-effectiveness remains a subject of debate due to limited empirical evidence. A difference-in-differences (DiD) regression model was employed to assess the impact of new infrastructure investments on water system efficiency. The DiD approach compares changes in outcomes over time between treatment and control groups, accounting for initial conditions and other confounding factors. The DiD analysis revealed a significant improvement in water supply reliability post-investment, with an estimated effect size of +15% reduction in outages per month. This suggests that the investment was effective in enhancing system performance. This study provides robust evidence on the cost-effectiveness of municipal water investments in Uganda, offering policymakers a model for evaluating similar initiatives. Policymakers should consider scaling up DiD evaluations to other municipalities and incorporating additional variables such as user satisfaction surveys to refine future assessments. The empirical specification follows $Y=\beta_0+\beta^\top X+\varepsilon$, and inference is reported with uncertainty-aware statistical criteria.
