"background": "Agroforestry practices have been proposed as a sustainable solution to enhance soil fertility in degraded environments such as urban slums. ", "purposeandobjectives": "To evaluate the yield gains and adoption rates of agroforestry practices among farmers in Kibera Slums, Nairobi, Kenya. ", "methodology": "A longitudinal study design was employed with quantitative data collection methods including surveys and soil analysis. ", "findings": "The preliminary findings suggest that integrated tree-crop systems led to a statistically significant increase in maize yields by 12\% (95% CI: 6%, 18%) compared to conventional farming practices. Farmer adoption rates increased from 40\% at baseline to 70\% after a year of intervention. ", "conclusion": "Agroforestry practices effectively improve soil fertility and can be scaled up for broader application in urban agriculture contexts.

", "keywords": "agroforestry, yield gains, farmer adoption, Kibera slums, Nairobi, soil fertility", "contributionstatement": "This study introduces a specific statistical model for predicting yield improvements in agroforestry systems. " --- The integration of trees with crops resulted in a statistically significant increase in maize yields by 12\% (95% CI: 6%, 18%) compared to conventional farming practices, indicating the effectiveness of agroforestry in enhancing soil fertility and crop productivity.
