AI in Diagnostics for Resource-Limited Healthcare
AI applications in diagnostics have shown promise in resource-limited healthcare settings, particularly for infectious diseases such as malaria and tuberculosis. A mixed-methods approach was employed, including a review of existing literature on AI diagnostics in Africa and empirical testing of AI models using clinical data from two major hospitals in Malawi. The analysis revealed that AI diagnostic tools achieved an accuracy rate of 92% in identifying malaria cases compared to expert clinicians' diagnoses. This finding indicates a significant improvement over traditional methods, with a confidence interval of ±5%. Furthermore, the cost savings associated with AI were substantial, reducing operational costs by approximately 30%. The findings suggest that AI can be effectively integrated into Malawi's healthcare system to improve diagnostic accuracy and reduce operational expenses. Further research should focus on scalability of AI models across different geographical regions and integration with existing health information systems.

ICT-Based Mental Health Support Services for Youth with Chronic Illnesses in Nigeria
Mental health issues are prevalent among youth living with chronic illnesses in Nigeria, yet traditional support services often fall short of their needs. A mixed-methods approach was employed, including a survey targeting participants (N=150) and qualitative interviews (n=20). Data were analysed using descriptive statistics and thematic analysis. Findings indicate that engagement levels are moderately high with service satisfaction scores averaging at 78% among the surveyed youth. Themes identified include barriers to access, perceived effectiveness of services, and suggestions for improvement. ICT-based mental health support services show promise in engaging youths with chronic conditions but require targeted interventions to enhance overall satisfaction and accessibility. Future research should focus on developing tailored educational programmes and expanding service availability through community partnerships.

Precision Agriculture Sensors in Nigerian Rice Farming Communities
Precision agriculture sensors are increasingly used to optimise crop management in various agricultural settings globally. In Nigeria, rice farming communities face challenges related to yield variability and soil health monitoring due to climate change and inconsistent farming practices. A mixed-method approach was employed, combining field trials with remote sensing techniques. A linear regression model was used to predict yield based on sensor readings of soil moisture and nutrient content. Uncertainty in predictions was quantified using standard errors from the model's output. The sensors demonstrated a significant positive correlation ($R^2 = 0.85$) with actual rice yields, indicating their reliability in predicting optimal planting conditions. Soil health monitoring revealed that varying soil pH levels affected nutrient uptake and crop yield variability by up to 15%. Precision agriculture sensors offer a reliable method for optimising rice farming practices in Nigeria, contributing to sustainable agricultural productivity and environmental stewardship. Farmers should adopt these sensors as part of their routine monitoring systems. Policies should support the integration of precision agriculture technologies into national agricultural strategies.

Strategies for Enhancing Digital Access in Rural South Africa
Digital access in rural South Africa is uneven, exacerbating socioeconomic disparities. Efforts to bridge this gap often focus on infrastructure and digital literacy programmes. The research employs mixed-methods, integrating surveys (N=200) with qualitative interviews (n=30). Data is analysed using thematic analysis supplemented by logistic regression models to predict access outcomes. Survey data reveals a significant proportion (45%) of rural residents lack basic digital literacy skills, while 18% have no internet access. Qualitative insights highlight challenges such as cost and technological barriers. The methodological framework identifies key areas for intervention to improve digital inclusion in rural South Africa, including targeted training programmes and community engagement initiatives. Public-private partnerships should be encouraged to fund and implement these interventions. Policy support is needed to address infrastructure gaps and reduce costs for users.

Adoption Dynamics of Drought-Tolerant Maize Varieties among Northern Ghanaian Smallholder Farmers
Drought-tolerant maize varieties have shown promise in enhancing agricultural productivity in arid regions of Africa. A mixed-methods approach combining surveys (n=200) and qualitative interviews with focus groups to explore perceptions, practices, and outcomes related to the adoption of these varieties. The proportion of farmers adopting drought-tolerant maize increased from 35% at baseline to 58% after one year, driven by perceived yield improvements and government support programmes. Three-year follow-up revealed sustained benefits in crop yields (mean increase: 20%) and economic returns ($10-20 per hectare). The study highlights the critical role of farmer education and government subsidies in fostering adoption and sustaining long-term gains from drought-tolerant maize varieties. Develop targeted extension services to enhance awareness and support for smallholder farmers adopting these technologies, alongside continued government incentives to ensure sustainable uptake and benefits over time.
