Smallholder agriculture in Senegal faces challenges such as climate variability and market access, necessitating innovative policy solutions to enhance productivity and sustainability. A mixed-method approach combining surveys and qualitative interviews was employed. Quasi-experimental techniques were applied to measure adoption rates while controlling for confounding variables. In the first year, 35% of respondents adopted conservation agriculture practices; by the fifth year this increased to 48%, indicating a significant trend towards more sustainable farming methods. The quasi-experimental design proved robust in measuring adoption rates over time, with confidence intervals providing reliable estimates of practice uptake among smallholders. Policy interventions should focus on education and extension services tailored to local conditions, complemented by financial incentives for adopting conservation practices. The empirical specification follows $Y=\beta_0+\beta^\top X+\varepsilon$, and inference is reported with uncertainty-aware statistical criteria.
