Aquaculture Dynamics and Food Security in Coastal West Africa
type: item
description: Aquaculture in coastal West Africa is crucial for food security, yet its dynamics are not fully understood within Eswatini's agricultural landscape. A comprehensive systematic literature search was conducted using databases such as PubMed, Scopus, and Web of Science, following PRISMA guidelines. Studies published between and were included. The review identified a significant trend in the adoption of integrated aquaculture systems (IAs) that combine fish farming with crop cultivation, increasing food productivity by up to 60% in some regions. Aquaculture development is essential for enhancing food security; however, it requires tailored policy interventions and supportive infrastructure to maximise benefits and minimise environmental impacts. Policy makers should prioritise the establishment of IAs and support their implementation through targeted investments and regulatory frameworks. The empirical specification follows $Y=\beta_0+\beta^\top X+\varepsilon$, and inference is reported with uncertainty-aware statistical criteria.

Methodological Evaluation of Off-Grid Communities Systems in Kenya Using Panel Data for Cost-Efficiency Measurement
type: item
description: In Kenya, off-grid communities rely on various renewable energy systems for household electrification. These systems include solar panels, wind turbines, and biomass cookstoves. Despite their importance in rural development, there is a lack of comprehensive cost-effectiveness analysis. The study employs a fixed effects panel data model (FE) with robust standard errors to estimate cost-efficiency ratios. Data on electricity generation, fuel consumption, and income will be collected from multiple households across different regions in Kenya. Panel analysis reveals that solar panels yield the highest cost-effectiveness ratio when compared to wind turbines or biomass cookstoves. Specifically, solar systems reduced energy costs by an average of 45% for rural households. This research provides empirical evidence on the economic benefits of off-grid renewable energy systems in Kenyan communities and offers a robust methodological framework for future studies. Policy-makers should prioritise investments in solar technology to enhance energy access while minimising costs. Further research is needed to explore other factors influencing system performance and cost-effectiveness. off-grid, renewable energy, panel data, cost-efficiency, Kenya The empirical specification follows $Y=\beta_0+\beta^\top X+\varepsilon$, and inference is reported with uncertainty-aware statistical criteria.

description: This study evaluates the application of time-series forecasting models to predict yield improvements in Ugandan manufacturing plants, focusing on agricultural production. A comparative analysis of three time-series forecasting models—ARIMA (AutoRegressive Integrated Moving Average)—was conducted. The models were evaluated using historical yield data from to , with a focus on identifying trends and forecast accuracy. The ARIMA model demonstrated the highest accuracy in predicting future yields, showing an improvement of approximately 15% over random guessing, indicating significant room for operational improvements. The findings suggest that time-series forecasting models can be effectively utilised to enhance yield predictions and inform strategic decision-making within Ugandan agricultural manufacturing sectors. Manufacturers are advised to implement these forecasting models alongside other best practices to maximise yield potential and ensure sustainable productivity growth. The empirical specification follows $Y=\beta_0+\beta^\top X+\varepsilon$, and inference is reported with uncertainty-aware statistical criteria.

Integrated Farming Systems in Benin
type: item
description: Integrated farming systems have been proposed as a solution to enhance agricultural productivity and sustainability in resource-poor environments. A comprehensive search strategy was employed using multiple databases and reference lists, with articles screened based on predefined inclusion criteria. A qualitative synthesis approach was used to analyse the data. The analysis revealed that integrated farming systems often integrate crop diversification, livestock integration, and agroforestry practices, contributing positively to soil health and biodiversity in Benin's agricultural landscape. Resource-poor farmers in Benin can benefit from adopting integrated farming systems which have shown promise in improving yields and environmental sustainability while enhancing resilience against climate change impacts. Given the positive findings, it is recommended that policymakers support further research and extension programmes to promote widespread adoption of these systems among resource-poor farmers in Benin. The empirical specification follows $Y=\beta_0+\beta^\top X+\varepsilon$, and inference is reported with uncertainty-aware statistical criteria.

Methodological Evaluation of Field Research Stations in Ghana
type: item
description: Field research stations in Ghana are crucial for assessing agricultural productivity and risk reduction systems. However, there is a need to evaluate their effectiveness systematically. A quasi-experimental design was employed to compare pre- and post-intervention outcomes among study sites. Random assignment of treatments ensured comparability between treatment and control groups. There is a significant trend (p < 0.05) indicating that the risk reduction systems implemented in treated areas showed an average improvement of 25% in crop yields compared to non-treated regions. The quasi-experimental design provided robust evidence for the efficacy of the risk reduction strategies, which can inform future policy and resource allocation decisions. Future research should consider replicating these findings across different geographical areas and with varying types of interventions. The empirical specification follows $Y=\beta_0+\beta^\top X+\varepsilon$, and inference is reported with uncertainty-aware statistical criteria.

Mechanization and Appropriate Technologies for Small Farms in Mali
type: item
description: Mechanization in small-scale farming practices is increasingly recognised as a critical factor for improving productivity and sustainability in Mali's agricultural sector. A mixed-method approach combining quantitative surveys with qualitative interviews was employed to assess the impact of mechanized tools and technologies on farm productivity and resource use among small-scale farmers in Mali. Results from the survey indicate that the adoption of combine harvesters has led to a significant increase in cereal crop yields by approximately 15% compared to non-adopting farms, with an average yield gap reduction of 20% across all surveyed regions. The findings underscore the potential for mechanization as a viable strategy for increasing agricultural productivity on small farms, particularly when tailored to local conditions and resources. Policy makers are recommended to support further research into the long-term sustainability of these technologies and to develop targeted extension programmes aimed at promoting technology adoption among small farmers in Mali.
