Abstract: This study aimed to evaluate the sustainability and long-term impacts of Conservation Agriculture (CA) practices on key agricultural metrics, such as soil health, crop productivity, and water retention, in the agroecological transition zone of Western Burkina Faso. Results indicated significant improvements in soil organic matter (22% increase), nutrient availability (15% increase in nitrogen), and water retention (18% higher moisture at flowering stage) in no-tillage plots with mulch application compared to conventional tillage. Maize yields increased by 34% under no-tillage with mulch, highlighting the positive impact of CA on crop productivity. In contrast, conventional tillage plots showed stable or declining yields due to soil degradation. The study concludes that CA, particularly no-tillage with mulch retention, enhances soil health, increases crop yields, and improves water use efficiency, making it a viable solution for sustainable agriculture in semi-arid regions. However, adoption barriers such as residue competition and limited access to equipment must be addressed for widespread implementation.
