Municipal water systems play a crucial role in agricultural productivity in Senegal by ensuring adequate irrigation water supply to crops and livestock. The study employs a DiD framework to analyse pre- and post-intervention data from Senegalese municipalities. The DiD model accounts for potential confounding factors such as climate variability by comparing the change in yields within treated (introduced municipal water systems) versus control (no new system introduced) groups. A significant increase of 15% in crop yield was observed in municipalities with newly installed municipal water systems compared to those without, indicating a substantial improvement in agricultural productivity. The DiD model effectively isolates the effect of municipal water systems on yields, demonstrating that these systems contribute positively to agricultural output in Senegal. Further research should explore the scalability and sustainability of municipal water systems across different geographical regions and socio-economic contexts in Senegal. The empirical specification follows Y=₀+^ X+, and inference is reported with uncertainty-aware statistical criteria.
