This study assessed the impact of climate change on hydrological cycle and crop production among smallholder farmers in Oyo State. 320 smallholder farmers were interviewed on their socio-demographic characteristics and their perceptions on drivers of climate change, practical manifestation and impact of water scarcity on crop production. Demographic data were analyzed with the aid of descriptive statistics (frequency and percentage) while the other parts which deal with the perceptions of the respondents were analyzed with inferential statistics (chi-square). The results of the study revealed that the practicing farmers agreed that human-induced activities such as fossil fuel, deforestation urban industrial expansion among others are the drivers of climate change. Also, most agricultural practitioners agreed with the listed options about the practical manifestation of climate change as observed in their farming system. The postulated hypothesis was tested with chi-square and the result revealed that water insecurity had significant impact on crop production with cal value of x2 107 and critical value 21.03 at 0.05 alpha level of significance. The study recommends that practicing farmers should be encouraged to adopt best practice that will reduce ozone layer depletion and global warming and encourage afforestation & agroforestry. Then, public awareness campaign should be intensified on impact of climate change on water insecurity and crop production.
