Designing Economically Viable Low-Cost Irrigation Systems for Drought-Affected Mali Terrains
type: item
description: Drought-prone areas in Mali face significant challenges in maintaining agricultural productivity, necessitating innovative low-cost irrigation solutions. A mixed-method approach combining literature review, expert consultations, and cost-benefit analysis to inform the development of a prototype system. The preliminary design of the low-cost irrigation system suggests an optimal proportion of water distribution channels at approximately 10 meters spacing for efficient water flow and minimal leakage, based on field trials in Mali’s arid regions. The designed systems are expected to reduce agricultural losses by up to 35% and increase farmer incomes by 20%, demonstrating their potential as economically viable solutions for Mali's drought-prone areas. Implement the recommended low-cost irrigation system designs in targeted pilot projects, followed by a comprehensive evaluation of their impact on livelihoods and environmental sustainability.

Methodological Evaluation of Transport Maintenance Depot Systems in Ethiopia Using Difference-in-Differences Approach for Cost-Effectiveness Analysis
type: item
description: Transport maintenance depots (TMDs) play a crucial role in ensuring the reliability of road transport infrastructure in Ethiopia. However, there is limited empirical evidence on their cost-effectiveness. The analysis employs a DiD model to assess changes in maintenance costs over time before and after the implementation of TMDs. The study uses administrative data from government records. A significant reduction in average maintenance costs was observed post-TMD implementation, with a decrease of approximately 15% compared to pre-depot periods. The DiD model effectively highlights cost savings associated with TMDs. These findings support the adoption and further expansion of such systems in Ethiopia's transport sector. Based on this study, it is recommended that Ethiopian authorities prioritise investment in comprehensive maintenance infrastructure to enhance road network resilience and reduce operational costs. The maintenance outcome was modelled as $Y_{it}=\beta_0+\beta_1X_{it}+u_i+\varepsilon_{it}$, with robustness checked using heteroskedasticity-consistent errors.

Cost-Effectiveness Assessment of Water Treatment Facilities in Nigerian Systems Using Panel Data Analysis
type: item
description: Water treatment facilities in Nigerian systems are crucial for ensuring safe drinking water and sanitation practices. However, their cost-effectiveness varies significantly across different regions, necessitating a methodological evaluation to optimise resource allocation. A panel data approach will be employed to analyse facility costs, operational efficiency, and user satisfaction across different regions. Econometric models will account for time-invariant and time-varying variables. Panel data analysis reveals significant cost differences (p<0.05) between northern and southern regions, with higher treatment costs in the north attributed to infrastructure challenges and varying water quality. The findings highlight the need for targeted interventions in high-cost regions, suggesting a shift towards more resilient and efficient facilities. Investment strategies should prioritise cost-effective solutions in northern regions, including pilot projects and technology upgrades that can be scaled up based on effectiveness. The maintenance outcome was modelled as $Y_{it}=\beta_0+\beta_1X_{it}+u_i+\varepsilon_{it}$, with robustness checked using heteroskedasticity-consistent errors.

Methodological Assessment and Cost-Efficiency Analysis of Water Treatment Facilities in Nigerian Municipalities Using Difference-in-Differences Models
type: item
description: Nigerian municipalities often face challenges in providing adequate water treatment facilities, leading to poor hygiene conditions and health outcomes. A DiD model was applied to analyse pre- and post-intervention data from municipal water supply records, focusing on changes in water quality indicators before and after facility upgrades. The model estimates the impact of these interventions by comparing municipalities that upgraded with those that did not. The DiD analysis revealed a statistically significant improvement in water treatment efficiency in intervention municipalities (p < 0.05), indicating an effective methodological approach for assessing such systems. This research provides robust evidence on the impact of upgrading water treatment facilities, contributing to better public health outcomes in Nigerian communities. Policy recommendations include prioritising investment in upgraded facilities and monitoring ongoing improvements to ensure sustained benefits.

Bayesian Hierarchical Model for Measuring Yield Improvement in Transport Maintenance Depots Systems in Rwanda
type: item
description: This study builds upon previous research that evaluated the yield improvement in transport maintenance depots systems within Rwanda's civil engineering sector. A Bayesian hierarchical model was employed to analyse data collected from transport maintenance depots across Rwanda. This model accounts for spatial and temporal variations in depot performance by incorporating random effects that reflect local characteristics and variability. The study utilised a dataset comprising monthly records of maintenance activities, quality control measures, and operational outcomes. The replication analysis confirmed the effectiveness of the Bayesian hierarchical model in estimating yield improvement across depots with an average accuracy rate of 95% when compared to the original study's results. The Bayesian hierarchical model demonstrated its reliability and suitability for evaluating transport maintenance depot systems, providing a robust framework for future research and policy development within Rwanda’s civil engineering sector. Future studies should consider expanding the dataset to include additional depots or different types of infrastructure projects. Additionally, further investigation into the specific factors influencing yield improvement could enhance our understanding of operational efficiency. The maintenance outcome was modelled as $Y_{it}=\beta_0+\beta_1X_{it}+u_i+\varepsilon_{it}$, with robustness checked using heteroskedasticity-consistent errors.

Methodological Evaluation of Power-Distribution Equipment Systems in Ethiopia Using Quasi-Experimental Design to Measure Risk Reduction
type: item
description: Power distribution equipment systems (PDEs) play a critical role in ensuring reliable electricity supply in Ethiopia's power grid. However, these systems are often vulnerable to failures that can lead to significant disruptions and risks. A quasi-experimental design was employed to compare PDE performance before and after interventions aimed at improving reliability. Data on equipment failures, maintenance records, and customer complaints were collected over two years. The analysis revealed a 25% reduction in power outages following the implementation of preventive maintenance strategies (95% CI: -30%, -20%). This quasi-experimental design provided robust evidence for the effectiveness of preventive measures in reducing operational risks associated with PDEs. Based on these findings, it is recommended that a comprehensive maintenance programme be implemented to further enhance system reliability and risk reduction.

Methodological Evaluation of Industrial Machinery Fleets Systems in Rwanda Using Multilevel Regression Analysis for Cost-Effectiveness Measurement
type: item
description: Industrial machinery fleets play a critical role in Rwanda’s manufacturing sector, but their operational efficiency varies widely. This study employs multilevel regression analysis to assess the impact of fleet management practices on maintenance costs and productivity across different sectors. The model incorporates fixed effects for geographical regions, which account for local economic conditions that influence fleet performance. There is a significant positive relationship between proper fleet management practices (such as regular maintenance schedules) and reduced maintenance costs by around 15%, with no adverse impact on productivity. The multilevel regression analysis has provided insights into the cost-effectiveness of industrial machinery fleets in Rwanda, highlighting the importance of standardised maintenance protocols across different sectors. Implementing a unified maintenance schedule and regular audits could lead to substantial savings without compromising operational efficiency.

Methodological Assessment of Power-Distribution Equipment Systems in Rwanda Using Quasi-Experimental Design for Risk Reduction Evaluation
type: item
description: Power distribution systems in Rwanda are critical for ensuring reliable electricity supply to urban and rural areas. However, there is a need to assess their effectiveness and identify potential risks. A quasi-experimental design was employed to analyse data from power distribution networks across different regions of Rwanda. This approach allowed for an assessment of system effectiveness without controlled experiments. The analysis revealed that the proportion of equipment failures in urban areas (75%) is significantly higher than in rural areas (30%), indicating a need for targeted interventions to reduce risks and improve reliability. This study highlights the importance of regional differences in power distribution system performance, underscoring the need for tailored risk reduction strategies. Investment should be prioritised in urban areas with higher failure rates, while monitoring rural networks to prevent future failures. Collaboration between government agencies and private sector stakeholders is essential for effective implementation. The maintenance outcome was modelled as $Y_{it}=\beta_0+\beta_1X_{it}+u_i+\varepsilon_{it}$, with robustness checked using heteroskedasticity-consistent errors.

Multilevel Regression Analysis for Evaluating Yield Improvement in Transport Maintenance Depots in Kenya
type: item
description: This study examines transport maintenance depots in Kenya to evaluate yield improvement through a multilevel regression analysis approach. The study utilizes multilevel regression analysis to evaluate yield improvement in transport maintenance depots across Kenya’s regions, considering both fixed effects and random effects models. Findings indicate a significant positive correlation (β = 0.53, p < 0.01) between investment levels and depot efficiency, with a 20% increase in yield observed for every $1 million invested across depots. The multilevel regression analysis highlights the importance of resource allocation and maintenance strategies to enhance transport infrastructure performance. Policy recommendations include increased funding for maintenance depots, targeted training programmes for technicians, and improved supply chain management to maximise yield improvements. The maintenance outcome was modelled as $Y_{it}=\beta_0+\beta_1X_{it}+u_i+\varepsilon_{it}$, with robustness checked using heteroskedasticity-consistent errors.

Time-Series Forecasting Model for Cost-Efficient Municipal Infrastructure Asset Management in South Africa
type: item
description: This case study focuses on municipal infrastructure asset management in South Africa, aiming to improve cost-effectiveness through advanced forecasting models. A time-series forecasting model was developed and applied to historical data from South African municipalities. Machine learning techniques were used to predict future costs based on current and past performance indicators. The model demonstrated a significant reduction in predicted maintenance costs by up to 15% over the next five years, with trends indicating consistent seasonal variations in infrastructure usage. The findings suggest that time-series forecasting can be an effective tool for municipal asset management, potentially saving substantial resources and improving financial planning. Municipalities should adopt this model to forecast costs more accurately and allocate budgets accordingly. Further research is recommended to validate these predictions across different regions.
