This study examined factors influencing farmers’ willingness to use digital decision support tools for climate change adaptation in Ogun State, Nigeria. A multistage sampling procedure was used to select 233 arable crop farmers. Data were collected through a structured interview schedule and analysed using frequencies, means, and multiple linear regression. The results show that the lack of adequate financial resources (𝑥 ̅= 2.98) was the most frequently experienced adaptation barrier by the farmers. While a slight majority (51.1%) had a high level of risk perception, about half (50.2%) of the farmers had high self-efficacy. Most of the farmers (83.7%) were highly willing to use DSTs. Education (β = 0.141), participation in agricultural associations (β = 0.209), land ownership (β = 0.177), risk perception (β = 0.161), and self-efficacy (β = 0.201) contributed significantly to farmers’ willingness to use DSTs for climate change adaptation. It is concluded that the farmers’ desire to use DSTs was strongly influenced by participation in anassociation, self-efficacy, mode of land ownership, risk perception, and education. Farmers’ participation in associations should be encouraged, while extension agents should improve adaptive efficacy through training and support to enhance farmers' willingness to use DSTs.
