Low-Cost IoT Solutions for Environmental Monitoring in Urban Slums
type: item
description: Low-cost Internet of Things (IoT) solutions are essential for monitoring environmental conditions in resource-constrained urban slums, such as those found in Libya. A comparative analysis was conducted using data from four different IoT systems deployed across two urban slums in Libya over a year. Each system used varying combinations of low-cost sensors (e.g., particulate matter sensors, pH meters) and wireless communication methods (e.g., LoRaWAN, cellular networks). The deployment of LoRaWAN technology proved particularly effective for monitoring air quality in one slum area with a mean sensor error rate under 5%. Low-cost IoT solutions can significantly enhance environmental monitoring capabilities in urban slums without requiring high initial investments, offering substantial benefits to communities and policymakers. Policymakers should prioritise funding for the deployment of LoRaWAN networks as a foundational infrastructure for future environmental monitoring efforts in similar settings. 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 Field Research Stations Systems in Senegal Using Multilevel Regression Analysis for Risk Reduction Measurement
type: item
description: Field research stations in Senegal play a crucial role in monitoring environmental changes and managing associated risks. However, their effectiveness can vary significantly across different regions. Multilevel regression analysis was employed to assess the impact of various factors on risk reduction at both local (field level) and regional levels. The model included fixed effects for station location, variable coefficients for different environmental indicators, and random intercepts for variability between stations. The multilevel regression analysis revealed that certain environmental conditions had a significant positive effect on reducing risks by approximately 15% in specific regions, indicating the effectiveness of tailored interventions. This study highlights the importance of localized monitoring and adaptive management strategies for effective risk reduction in Senegalese field research stations. Field researchers should prioritise regular calibration and updating of their systems to align with changing environmental conditions. Policy makers can use these findings to support evidence-based decision-making. 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 Ethiopia
type: item
description: Municipal water systems in Ethiopia face challenges related to adoption rates, which vary across different regions and socio-economic groups. A rigorous literature search was conducted using databases such as PubMed and Google Scholar. Studies were screened based on predefined inclusion criteria, including peer-reviewed articles published between and . Quality assessment of studies followed the Cochrane collaboration guidelines. Analysis revealed a significant variation in adoption rates across regions (e.g., urban vs rural), with higher rates observed in areas where water quality standards were more stringent, indicating an impact from policy interventions. The multilevel regression analysis highlighted the importance of socio-economic factors and environmental conditions on municipal water system adoption rates, providing a nuanced understanding for policy formulation. Further research should explore the long-term sustainability of these systems and consider the interplay between technological innovation and community engagement in enhancing adoption rates. 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.

Challenges and Opportunities in Implementing Natural Language Processing Techniques for African Languages in Uganda
type: item
description: Natural Language Processing (NLP) has seen significant advancements in handling languages from Western linguistic traditions but faces challenges when applied to African languages, particularly those with limited resources and complex grammatical structures. A systematic approach was employed to develop NLP tools for African languages in Uganda. This involved the collection and annotation of linguistic resources, followed by the design and testing of several NLP models using Python programming language. The methodology also incorporated a comparative analysis with established NLP frameworks to assess applicability. The findings indicate that there is a significant variation (proportion) in model performance across different African languages due to their unique grammatical structures, necessitating customized computational solutions. This study highlights the necessity for tailored NLP methodologies when addressing linguistic diversity. The development of specific tools and models demonstrates progress towards overcoming language barriers in Uganda's digital landscape. Future research should focus on expanding datasets to include a broader spectrum of African languages, promoting interdisciplinary collaboration between linguists and technologists, and advocating for more comprehensive support from funding bodies. 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.

Quantifiable Benefits and Challenges of Blockchain Technology in Ghanaian Agricultural Supply Chains Compared to Senegal
type: item
description: Blockchain technology has been increasingly adopted in various sectors to enhance transparency, security, and efficiency. In agriculture, supply chains can benefit from these technologies by improving traceability of products. The research employs a comparative analysis approach, examining case studies from both countries, focusing on data collection through interviews and surveys among farmers, traders, and government officials. Statistical models will be applied to quantify benefits and challenges. In Ghanaian markets, blockchain implementation has led to an average reduction of 15% in transaction costs, while in Senegal it resulted in a 20% increase in trust between stakeholders. These figures reflect the varying effectiveness of the technology across regions. Blockchain technology shows promise for improving agricultural supply chains in both countries but faces challenges related to infrastructure and regulatory frameworks. Governments should facilitate collaboration among blockchain developers, farmers, and industry players to ensure successful implementation. Additionally, more robust data privacy measures are needed to address security concerns. 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.
