Livelihood Empowerment Through Aquaponics in Urban Coastal Ghana
Urban coastal communities in Ghana face challenges related to food security and economic viability due to limited land availability for traditional agriculture. A systematic review approach was employed to identify relevant literature, analyse data from studies conducted between and , and synthesize findings related to aquaponics in Ghanaian urban coastal settings. Aquaponic systems demonstrated an average yield increase of 40% over conventional farming methods, contributing significantly to food security by providing fresh produce year-round. Economic viability was enhanced through cost-effective operation and potential for off-season sales. The review supports the adoption of aquaponics as a viable livelihood strategy in urban coastal areas of Ghana, offering improved economic returns alongside sustainable agriculture solutions. Policy makers should incentivize the development and implementation of aquaponic systems by providing subsidies and training programmes for farmers. Additionally, there is a need to expand research on long-term ecological impacts and market access strategies.

Sustainable Pest and Disease Management Practices in Maize Production Systems of Tanzania
Maize is a crucial staple crop in Tanzania's agricultural landscape, contributing significantly to food security and income generation for smallholder farmers. Field trials were conducted across five regions of Tanzania, employing a randomized complete block design with twenty plots per region. Data collection included weekly observations on pest incidence, disease severity ratings, and yield measurements. In Region 3, the application of neem oil reduced maize foliar diseases by an average of 45% compared to untreated control plots (p < 0.01), demonstrating a statistically significant reduction in disease prevalence. The study concludes that integrated pest and disease management strategies incorporating neem oil can be effective in maintaining high maize yields without excessive reliance on chemical pesticides. Farmers should adopt the use of natural pest control methods such as neem oil to enhance their crop yields sustainably, alongside continuous monitoring and adaptation of best practices.

Effectiveness of Soil Moisture Monitoring Systems on Irrigated Maize Crops in Ethiopia,
Soil moisture monitoring systems have been used to optimise irrigation practices in various agricultural settings, but their effectiveness on maize crops under specific Ethiopian conditions has not been thoroughly evaluated. A randomized controlled trial was conducted across three different farms representing diverse agricultural conditions. Soil moisture sensors were installed to monitor soil moisture levels at various depths, and farmers were instructed on adjusting irrigation timings based on sensor readings. Yield data and water consumption records were collected over a year to assess the system's effectiveness. Findings suggest that by reducing unnecessary irrigation cycles by approximately 15%, maize yields increased by an average of 20% compared to traditional manual monitoring methods, with significant reductions in water usage without compromising crop productivity. The sensor readings showed a strong correlation (R² = 0.89) with actual yield variations. The soil moisture monitoring systems demonstrated enhanced precision and efficiency in irrigation management, leading to improved maize yields and reduced water consumption. Farmers should be trained on the use of these systems for optimal performance and integrated into routine agricultural practices. Government support is recommended to facilitate adoption at a larger scale.

Economic Outcomes and Digital Divide Analysis of Mobile Payment Adoption Among Urban Youth in Lagos, Nigeria
In Nigeria, mobile payment adoption among urban youth in Lagos has been observed to influence economic outcomes such as transaction frequency and service reliability. Data was collected through structured interviews from a sample size of 200 urban youths across varying socioeconomic backgrounds. A logistic regression model will be used to assess the relationship between mobile payment adoption and economic outcomes, adjusting for potential confounders. Mobile payment adoption among urban youth in Lagos showed significant variation by socio-economic status (SES), with higher SES individuals being more likely to adopt digital payments and experience improved transaction frequency (p < 0.05). The findings suggest that while mobile payments are increasingly accessible, they may exacerbate economic disparities when not widely adopted across all socioeconomic groups. Public policies should focus on enhancing access to financial services for lower SES youth in Lagos to mitigate the digital divide and improve overall economic outcomes. The empirical specification follows $Y=\beta_0+\beta^\top X+\varepsilon$, and inference is reported with uncertainty-aware statistical criteria.

Digital Literacy Programmes among Adolescent Farmers in Kenya's Coast Province
Adolescent farmers in Kenya's Coast Province face challenges accessing and utilising information technology (IT) for agricultural advancement. A mixed-methods approach was employed, including surveys, focus groups, and interviews with participants aged 15-18 years. Data were analysed using thematic analysis for qualitative insights and descriptive statistics for quantitative data. Among the 200 adolescent farmers surveyed, 75% reported improved access to IT resources post-programme participation, particularly in accessing agricultural advisories through mobile applications (M = 64%, SD = 12%). Digital literacy programmes significantly enhanced adolescents' ability to use IT for agricultural purposes, with notable improvements in crop management and livestock health monitoring.
