Senegalese agriculture is threatened by climate change effects, affecting rainfall variability both at interannual and interdecadal timescales. Using FAO’s AquaCrop crop-growth model, we tested the efficiency of an in situ water harvesting technique - tied ridges - for maize cropping in the Fatick region in Senegal in response to changes in temperature and precipitation with different fertility levels and different soils. Results showed that tied ridges did not significantly impact maize yields considering the current climate and soil fertility. The rainfall amount was enough for maize production and to avoid water stress during the cropping season. Under perturbed climates and, especially in years with low average rainfall amounts, high losses in yield were registered under optimal fertility conditions (up to 80%). The most substantial effect was obtained when tied ridges were simulated on clay soil, enhancing yields by 5.6% and 13% at actual and optimal fertility conditions, respectively. Our results highlighted how the current maize production in the Fatick region in Senegal is not significantly water constrained in the current climate scenario, while it could be potentially impacted by climate change in the near future. In a pessimistic climate change scenario, in situ water harvesting can potentially avoid excessive crop losses.
