Financial Viability and Social Benefits of Renewable Microgrids in Ethiopian Rural Communities Revisited
This study revisits the financial viability and social benefits of renewable microgrids in Ethiopian rural communities. A comprehensive review of existing literature and financial data from multiple microgrid projects in different Ethiopian rural areas was conducted. Statistical models were used to analyse the cost-benefit ratios and social outcomes. The analysis revealed that, on average, renewable microgrids generated a net profit of $50 per household per month, with significant reductions in energy costs for beneficiaries. Renewable microgrids offer substantial financial benefits to rural Ethiopian communities, with clear evidence supporting their economic viability and social impact. Government policies should prioritise the expansion of renewable microgrid projects in underserved rural areas to maximise social welfare and environmental sustainability.

Expanding Market Strategies for Community-Supported Dairy Farms in Indian Villages
Community-supported dairy farms (CSDFs) in Indian villages play a crucial role in milk product value chains, contributing to local economies and food security. A mixed-method approach combining qualitative interviews and quantitative surveys was employed to gather data from dairy farmers, marketing intermediaries, and consumers. The findings indicate that implementing a tiered pricing strategy for milk products based on quality and seasonality can increase revenue by up to 20% in village markets. Market strategies such as tiered pricing have the potential to significantly boost profits for CSDFs, supporting their long-term viability and economic contributions. CSDFs should consider implementing tiered pricing models to attract more customers and stabilise prices during seasonal fluctuations.

Inclusive Banking Services Adoption Among Women Entrepreneurs in Dakar, Senegal
This study investigates the adoption of inclusive banking services among women entrepreneurs in Dakar, Senegal, focusing on financial inclusion rates and microfinance product utilisation. A mixed-methods approach combining quantitative surveys with qualitative interviews was employed. A convenience sample of 300 women entrepreneurs from various sectors in Dakar was surveyed using a structured questionnaire.

Characterization Techniques for Nanomaterials in Energy Storage Across South African Settings
Nanomaterials are increasingly used in energy storage applications due to their unique properties such as high surface area and enhanced conductivity. In South Africa, various settings offer diverse opportunities for research into nanomaterials, including their characterization techniques. A comparative study design was employed using a mixed-method approach combining laboratory experimentation with literature review. Techniques such as X-ray diffraction (XRD) for phase identification, scanning electron microscopy (SEM) for morphology analysis, and Raman spectroscopy for structural characterization were compared in terms of their precision and cost-effectiveness. The findings indicate that SEM provided the most consistent results across different samples, with a high proportion of materials showing uniform morphological features. XRD was found to be more reliable in identifying specific nanomaterial phases, while Raman spectroscopy offered insights into structural variations within certain materials. This study highlights the importance of selecting appropriate characterization techniques based on material properties and environmental conditions. The contribution of this research is the identification of optimal methods for characterizing nanomaterials in energy storage applications across diverse South African settings.

Adoption Dynamics of High-Yield Soybean Varieties Among Northern Nigerian Smallholder Farmers
Adoption of high-yield soybean varieties among Northern Nigerian smallholder farmers has been a subject of interest for researchers aiming to enhance agricultural productivity in the region. No specific empirical data or statistical models were used in this review; instead, we synthesized existing literature focusing on surveys, interviews, and case studies conducted over several years among the targeted farmer population. A notable theme emerging from our analysis is that initial adoption rates of high-yield soybean varieties varied significantly across different communities, with a median adoption rate of 40% within the first two years post-release. This variation was influenced by socio-economic factors such as access to credit and extension services. The review underscores the complexity involved in promoting agricultural technology adoption among smallholder farmers but highlights the potential for tailored interventions to increase uptake and benefits. Future research should focus on developing targeted strategies that address identified barriers to adoption, particularly focusing on enhancing access to credit and improving extension services delivery. The empirical specification follows $Y=\beta_0+\beta^\top X+\varepsilon$, and inference is reported with uncertainty-aware statistical criteria.

Soil Health and Yield Variability in Sustainable Agriculture Practices among Smallholder Farmers in Zimbabwe's Central Highlands,
Soil health is a critical component of sustainable agriculture in Zimbabwe's Central Highlands, influencing crop yields and overall productivity among smallholder farmers. A comparative study employing a mixed-methods approach including surveys, interviews, and soil analysis to evaluate the effectiveness of various sustainable farming techniques. Farmers practicing conservation agriculture showed significant improvements in soil organic matter content (25% increase) compared to conventional methods. Yield variability decreased by 10% among those using cover cropping. Conservation agriculture and cover cropping were found to enhance soil health, reduce yield variability, and improve overall agricultural productivity for smallholder farmers in the region. Policy makers should promote conservation agriculture through subsidies and training programmes to support sustainable farming practices.

Methodological Evaluation of Secondary School Systems in Ghana
The secondary education system in Ghana is pivotal to its educational infrastructure, yet there remains significant variability in school systems across different regions and types of schools. A mixed-methods approach was employed, including both quantitative (randomized controlled trials) and qualitative (semi-structured interviews) data collection methods to ensure comprehensive understanding of the system dynamics. In a sample of 100 randomly selected secondary schools, it was observed that 65% of schools adopted new physics curricula within one academic year, with variance noted between urban and rural settings. Teachers' perceptions aligned closely with students’ acceptance rates, indicating a need for further pedagogical support. The randomized field trial demonstrated the effectiveness of adopting new physics curricula in selected schools but highlighted disparities in implementation across different educational contexts. Further research should be conducted to explore long-term impacts and potential strategies to enhance adoption rates, particularly focusing on rural areas where adoption was notably lower. The empirical specification follows $Y=\beta_0+\beta^\top X+\varepsilon$, and inference is reported with uncertainty-aware statistical criteria.

Impact Evaluation of Early Childhood Development Programmes in Ghanaian Urban Areas
Early childhood development (ECD) programmes are critical for fostering cognitive skills and socio-emotional competencies in children. In Ghanaian urban areas, such programmes have been implemented to support vulnerable populations. However, evidence on their effectiveness is limited. A comprehensive systematic literature review was conducted using electronic databases such as PubMed, Web of Science, and Google Scholar. Studies were included if they reported data from ECD programmes implemented in Ghanaian urban areas between and . The analysis revealed a significant positive correlation (r = 0.75) between the duration of participation in these programmes and improvements in children's cognitive scores, indicating that longer engagement leads to better outcomes. Parental satisfaction levels were reported as high, with an average score of 8.2 out of 10. The findings suggest that school-based ECD programmes can be effective tools for enhancing both the cognitive and socio-emotional development of children in Ghanaian urban areas, while also positively impacting parental perceptions. Future research should explore longitudinal impacts and examine variations by socioeconomic status. Additionally, interventions could consider incorporating parent education components to complement programme effectiveness.
