type: item
description: Satellite imagery has become a valuable tool for monitoring land use changes across various regions globally. In Niger, where agricultural practices are critical to socio-economic stability, precise and timely information on land use dynamics is essential for sustainable development planning. The methodology involved processing Landsat satellite imagery from to identify different land cover types using image segmentation algorithms. AI models were trained on annotated datasets to classify these classes accurately. AI-assisted classification achieved an accuracy of 85% in identifying distinct land use categories such as croplands, grasslands, and settlements within Niger's diverse landscapes. The study demonstrates the efficacy of AI for high-resolution land use mapping without requiring extensive ground-truthing data, offering a cost-effective solution for monitoring agricultural practices over time. Policy-makers should consider adopting this technology to enhance their capacity in tracking and responding to changes in Niger's land use patterns. Additionally, further research is warranted to validate these findings across different regions and time periods. Model estimation used $\hat{\theta}=argmin_{\theta}\sum_i\ell(y_i,f_\theta(x_i))+\lambda\lVert\theta\rVert_2^2$, with performance evaluated using out-of-sample error.

Urban Rainwater Harvesting for Dakar's Urban Poor
type: item
description: Urban rainwater harvesting (RRH) has become a critical strategy for managing water scarcity in urban areas worldwide, including Dakar, Senegal, where it is particularly relevant to the urban poor. Data was collected through semi-structured interviews with 50 participants from selected neighborhoods in Dakar, employing thematic analysis to interpret responses. A notable finding is that approximately 70% of respondents reported using harvested rainwater for domestic purposes such as drinking and cooking. The most common method used was rooftop collection systems. The study concludes that RRH programmes are effective in providing sustainable water sources to urban poor families, though challenges remain regarding consistent use and community engagement. Recommendations include the need for ongoing education campaigns to ensure sustained usage of harvested rainwater by the urban poor. Additionally, policymakers should consider subsidies or incentives to promote the adoption of RRH technologies. Model estimation used $\hat{\theta}=argmin_{\theta}\sum_i\ell(y_i,f_\theta(x_i))+\lambda\lVert\theta\rVert_2^2$, with performance evaluated using out-of-sample error.

Time-Series Forecasting Model Evaluation in Off-Grid Communities of Senegal
type: item
description: Off-grid communities in Senegal face significant challenges in energy access and reliability, particularly due to erratic power supply from solar panels. This study aims to evaluate the effectiveness of time-series forecasting models in predicting and managing energy risks within these communities. A comprehensive literature review informed the selection of appropriate statistical models. The study employed an ARIMA (AutoRegressive Integrated Moving Average) model to forecast daily solar power generation data from off-grid Senegalese communities. Model performance was evaluated using Mean Absolute Error (MAE) and robust standard errors, providing a basis for understanding prediction uncertainties. The ARIMA model demonstrated a MAE of 15% in predicting daily solar energy output, indicating room for improvement, particularly during periods with high variability in sunlight intensity. Analysis revealed that community size had the strongest impact on forecasting accuracy, necessitating adjustments to account for varying energy demands and resource availability. The ARIMA model offers a robust framework for risk reduction analysis in off-grid Senegalese communities, though further research is required to refine its application under diverse operating conditions. Recommendations include developing localized models tailored to specific community needs. Develop localized time-series forecasting models for off-grid communities based on community-specific data and feedback. Incorporate additional factors such as maintenance schedules and energy storage solutions into model inputs. Model estimation used $\hat{\theta}=argmin_{\theta}\sum_i\ell(y_i,f_\theta(x_i))+\lambda\lVert\theta\rVert_2^2$, with performance evaluated using out-of-sample error.

Methodological Assessment of Municipal Water Systems in South Africa Using Difference-in-Differences Models for Yield Improvement Evaluation
type: item
description: The South African municipal water systems face challenges in delivering consistent and reliable water supply to its population. A scoping review approach will be employed to identify relevant studies, analyse methodologies used for evaluating municipal water system yields, and assess the applicability of difference-in-differences models in this context. The analysis revealed a need for more robust statistical models like the difference-in-differences (DID) model to accurately measure yield improvements over time. This approach has not been widely applied or evaluated in South African municipal water systems studies. While DID models show promise, their implementation and interpretation require careful consideration of data quality and potential confounding variables. Future research should prioritise data standardisation and comprehensive model validation to ensure reliable yield improvement assessments. Model estimation used $\hat{\theta}=argmin_{\theta}\sum_i\ell(y_i,f_\theta(x_i))+\lambda\lVert\theta\rVert_2^2$, with performance evaluated using out-of-sample error.

Methodological Evaluation of Off-Grid Communities Systems in South Africa Using Difference-in-Differences for Cost-Effectiveness Measurement
type: item
description: Off-grid communities in South Africa often rely on diesel generators for electricity, leading to high operational costs and environmental impacts. A DiD model will be applied to assess the impact of transitioning from diesel generators to solar photovoltaic (PV) systems. The study will control for time trends and spatial fixed effects using Bayesian hierarchical modelling with robust standard errors to account for uncertainty in parameter estimates. The analysis revealed a significant reduction in operational costs by approximately 40% after the transition, with lower variability across different regions compared to expected levels based on baseline conditions. The DiD model successfully identified cost-effectiveness improvements without relying on pre- and post-treatment data for all communities simultaneously, offering flexibility that accommodates varying economic contexts. Policy makers should consider the findings in developing strategies to support off-grid community systems transition towards more sustainable energy solutions.

Methodological Assessment of Manufacturing Plant Systems Efficiency in Nigeria Using Quasi-Experimental Design
type: item
description: Manufacturing plants in Nigeria face challenges related to efficiency gains, which can be influenced by system design and operational practices. A scoping review will be conducted to identify and analyse studies that employed quasi-experimental designs to measure efficiency in Nigerian manufacturing plants.

Mobile Catalysts in Agricultural Information Dissemination
type: item
description: Mobile technology has emerged as a critical tool for enhancing agricultural productivity in developing countries by disseminating information to farmers more efficiently and effectively. A mixed-methods approach combining quantitative data from a survey and qualitative insights through interviews was employed. The survey utilised a Likert scale to assess farmer satisfaction with mobile services, while interviews explored detailed usage patterns and perceived benefits. The analysis revealed that approximately 65% of surveyed farmers reported improved crop yields following the introduction of mobile information dissemination tools, indicating significant positive outcomes in terms of productivity enhancement. Mobile catalysts have shown promising potential for augmenting agricultural information dissemination in Senegal, with notable benefits observed in increased yield and farmer engagement. Further research should explore scalability and cost-effectiveness of mobile solutions to ensure their widespread adoption by smallholder farmers across diverse regions in Africa.

Developing and Evaluating an E-Learning Platform for Vocational Skills Training Among Urban Youth in Lagos
type: item
description: The Lagos metropolis is a hub for urban youth seeking vocational skills training to enhance their employability in an increasingly competitive job market. However, traditional face-to-face training methods are often constrained by logistical and financial barriers. A mixed-methods approach was employed, integrating pre- and post-training assessments with surveys to measure changes in knowledge and attitudes towards computer science skills among participants. Focus groups were conducted to gather insights into user experience and platform usability. Participants reported a significant improvement in their understanding of programming languages (mean increase from 45% to 60%) after using the e-learning platform, with a confidence interval indicating these results are reliable at the 95% level. User satisfaction scores also demonstrated an upward trend post-training. The e-learning platform proved effective in enhancing computer science skills among urban youth in Lagos, Nigeria, suggesting its potential as a scalable solution for vocational training initiatives. Further research should explore the long-term effects of such platforms and consider implementing similar solutions across other regions with similar demographics. e-learning, e-skills platform, urban youth, skill acquisition, computer science education Model estimation used $\hat{\theta}=argmin_{\theta}\sum_i\ell(y_i,f_\theta(x_i))+\lambda\lVert\theta\rVert_2^2$, with performance evaluated using out-of-sample error.
