Poor identification of proper communication channels, coupled with farmers’ limited involvement in content creation and selection of communication methods, significantly hampers their access to essential agricultural information. This challenge becomes even more critical in situations where farmers have restricted access to established communication channels or lack the technical expertise to utilize the channels effectively. This study was conducted to determine preferred communication channels for accessing Climate-Smart Agriculture (CSA) messages by smallholder farmers in Dowa, Nkhotakota and, Phalombe districts of Malawi. Specifically, the study sought to identify communication channels for disseminating CSA messages, determine farmer’s access to communication channels for disseminating CSA messages, ascertain farmer’s preference for communication channels and analyze the relationship between farm and farmers’ characteristics and preference for communication channels for accessing CSA messages. The study was grounded on two theories: the communication theory and the Uses and gratification theory. The study used qualitative and quantitative research methods and involved 320 smallholder farmers. It was established that primary communication channels for disseminating CSA messages were extension workers (26%), radio (25%), and lead farmers (25%). In terms of access, farmers had more access to the radio (6.83 days per month) followed by lead farmers (4.84 days per month). The study also revealed that farmers preferred accessing CSA messages through extension workers (29%), followed by lead farmers (28%), and radio (25%). Chi-square analysis showed a significant relationship between farm and farmer characteristics such as gender and choice of radio, extension worker, and lead farmer; farm size was associated with the choice of radio, extension worker, and lead farmer; education was associated with the choice of posters, while age was associated with the choice of lead farmer. The study concluded that preference towards communication channels was influenced by farm and farmer characteristics. Consequently, it is advised that prior to disseminating CSA messages, a comprehensive analysis of socio-demographic and farmer characteristics be conducted. This approach ensures effective communication of the messages to the targeted farmers.
