  • 1. SIMULATING THE IMPACT OF CLIMATE CHANGE ON YIELDREDUCTION OF VEGETABLE CROP PROPAGATION USING CROPWAT-8 by EWEMOJE, T. A. and ASHAOLU, P. O.Agricultural and Environmental Engineering Department, University of Ibadan, Ibadan, Nigeria. Introduction Results• Man’s activity such as deforestation Inconsistent variability in climate has lead to climate change. change under CD, NI and DI.• Climate change has both negative and Yield reduction was low under CD positive impact on agriculture. and high for both DI and NI.• This impact can be determined using No significant difference (p<0.05) sensitivity analysis. between CD and NI.• A simulation model is needed to carry Significant differences existed, at p < out sensitivity analysis. 0.05 between DI and CD, also• CROPWAT model was used. between at DI and NI. Coefficient of determination (R2) is Objectives close to 1 therefore model is valid.• Simulation of climate change impact Yield reduction was low between July on vegetable propagation using and October, depicting better yield CROPWAT-8. during rainy season.• Analyse weather forecasting for a 9- year period for vegetable crop yield in response to climate change.• Model crop yield sensitivity to changes in weather data in a tropical environment. Methods Source: www.fao.org/nr/water• Study area: Ibadan, Nigeria. Conclusion• Data: Climatic, Soil and Crop. Climate change is not constant• Irrigation Schedule: No Irrigation, phenomenon, its ever changing. irrigation (NI) and Critical Depletion Critical depletion is most preferred (CD) with Definite Interval (DI). under uncertainty in variability of• Statistics: Descriptive (Mean), Least climate change. Square Difference (LSD) and T test. Planting should be done between July and October; to reduce impacts of climate change on yield.
