This study examines the effect of climate change on the health of rural farmers in Nigeria. It is based on structured interviews with 98 respondents and the collected data were analysed through the use of frequency count, simple percentages and Pearson product moment correlation (PPMC). The study reveals a significant relationship between socio-economic characteristics of the respondents and how they perceived the effect of climate change on their health. The majority of the respondents received climate change information through radio or television; only a few had received climate information from a research institute. The study concludes that malaria is the most common and severe disease affecting the respondents. The authors recommend that the Nigerian government should educate farmers through the mass media to combat climate change. Moreover, climate change adaptation policies and strategies need to be considered as integral components of Nigeria's economic growth strategy.
