The study investigated the determinants of small holder farmers’ decisions to adopt climate variability measures in Oron, a Nigerian coastal settlement. Ideally, the study sought to establish the influence of farmers’ socio-economic characteristics on their choice of climate variability mitigation measures. The study hypothesized that farmers’ socio-economic characteristics such as gender, education, age, household size, marital status, income level, exposure to information on climate change, access to credit and farming experience all positively influence farmers’ decisions to adapt to climate change. The study used cross sectional data collected between December 2020 and January 2021 farming season through the administration of 200 structured questionnaires to 8 randomly selected farming communities based on probability proportional to size. The data was complemented by information obtained through focus group discussions, and direct field observations. The results of the Stepwise Regression Model revealed that education, non-farm income, farming experience, access to climate information and credit facilities significantly influence farmers’ decisions to adapt to climate change mitigation measures in the study area as these variables accounted for 36%, 21.23%, 13.42% and 9.49% respectively. This leads to the suggestion that there is need for the establishment of adult literacy programme in the farming communities as means of improving the literacy levels of the farmers as well as the need for government to develop and strengthen institutional mechanisms that support the farmers to adapt to climate change/variability through increase access to credit from micro finance institutions and other formal channels.
