Nutritional Education Programmes for Pregnant Women in Nairobi Slums
Nutritional deficiencies during pregnancy are prevalent in Nairobi slums, affecting maternal and infant health outcomes. A mixed-methods approach was employed including surveys and focus group discussions to assess programme efficacy. Among participants, there was a significant increase (p < 0.05) in the proportion of women who practiced exclusive breastfeeding from 30% to 60% after participation in the education programmes. The findings suggest that nutritional education can lead to substantial behavioural changes and improved health outcomes among pregnant women in Nairobi slums. Further research should explore long-term impacts and scalability of these interventions.

Enhancing Soil Health and Fertility through Agroecological Approaches in Ghana
Ghana faces challenges in maintaining soil health due to intensive farming practices, leading to decreased fertility and productivity. Agricultural field trials were conducted across three regions in Ghana, employing mixed methods including surveys and soil analysis to assess changes in soil organic matter content (SOC) over two growing seasons. Inter-cropping with leguminous plants significantly increased SOC by an average of 15% compared to monoculture practices, although the effect was more pronounced in regions with higher rainfall. Agroecological approaches have shown promise in improving soil health and fertility, particularly when integrated with local agricultural knowledge and resources. Farmers should be provided with training on agroecological practices and access to locally produced compost as a cost-effective means of enhancing soil quality.

Development and Adoption Dynamics of Digital Agricultural Extension Services in Southern Mozambique
Digital agricultural extension services have emerged as a promising tool for enhancing productivity and sustainability in rural communities of Southern Mozambique. A mixed-methods approach combining quantitative surveys (n=500) and qualitative interviews was employed to assess service usage patterns and perceptions over a two-year period. Users reported an average adoption rate of 42%, with higher satisfaction levels among those who used the services frequently. A logistic regression model estimated that farmers using digital platforms for more than six months had a 1.5 times greater likelihood of reporting high satisfaction (95% CI: [1.1, 2.0]). Digital agricultural extension services show promise in improving farmer productivity and engagement with agribusiness innovations. Further research should explore the scalability of digital platforms and their impact on smallholder farmers' income levels.

Sustainable Practices in Coffee Production Among Smallholder Farmers in Kenya's Central Highlands
This review examines sustainable coffee production practices among smallholder farmers in Kenya's Central Highlands. A thematic synthesis approach was used to review and analyse peer-reviewed articles, grey literature, and case studies published between and focusing on coffee production in the Central Highlands of Kenya. The analysis included a total of 35 documents from various sources including journals, conference proceedings, and government reports. A thematic synthesis revealed that over 70% of smallholder farmers adopted shade-grown coffee practices, which not only enhanced biodiversity but also increased overall productivity by up to 20%. However, there was a significant variation in the application of these practices across different regions within the study area. The review underscores the importance of integrating sustainable practices into coffee farming systems to achieve both economic and environmental sustainability. Key recommendations include fostering knowledge transfer programmes and providing incentives for farmers who adopt shade-grown crops. Developed strategies should aim at promoting the adoption of shade-grown coffee by smallholder farmers, particularly through targeted training sessions and financial support mechanisms.

Aquaculture Dynamics and Food Security in Coastal West Africa
Aquaculture in coastal West Africa has evolved over decades, significantly impacting food security. A comprehensive search of academic databases was conducted using keywords related to aquaculture and food security. Studies published between and were included if they met specific criteria for relevance and quality. Findings indicate that while aquaculture expansion has led to increased fish production, the proportion of households relying on this source for their dietary needs varied significantly across regions, from 45% in Botswana to over 70% in some coastal communities. The review highlights challenges such as limited access to feed and disease management resources, which threaten sustainable aquaculture development. It underscores the importance of integrated approaches that address socio-economic factors alongside biological aspects. Policy makers should prioritise investments in infrastructure, training programmes for farmers, and research into disease-resistant strains to ensure long-term food security and economic stability in coastal West African regions.

Integrated Pest Management Synergy Programmes for Coffee Farmers in Rwanda's Highlands
Integrated Pest Management (IPM) programmes have been implemented globally to reduce pesticide use while maintaining crop yields and quality. In Rwanda's coffee-growing highlands, IPM has shown promise in enhancing sustainability by reducing chemical inputs without compromising productivity. A mixed-methods approach combining qualitative interviews with quantitative assessments of pest management practices and crop yields. Data were collected from 50 randomly selected coffee farms across three districts in Rwanda's central highlands. The analysis revealed that the integrated pest management programmes led to a significant reduction (p < 0.01, CI: -25% to -18%) in pesticide application rates compared to conventional practices, without compromising crop health or yield stability. The findings suggest that IPM can effectively reduce pesticide use on coffee farms while maintaining high-quality yields and environmental sustainability. Farmers should be provided with training and support for sustainable pest management techniques. Government agencies are encouraged to promote and subsidize these programmes to facilitate wider adoption in the region.
