Understanding the reasons why smallholder farmers do not use financial instruments to protect themselves against losses brought on by climate change concerns is currently a subject of rising relevance. Getting to the bottom of the underlying issues contributing to this status is important for future designs of financial innovations like a weather insurance index (WII) that can help farmers hedge their losses. Therefore, this study considered testing the 5 technology characteristics that Rodgers identified for uptake to take place. These include trialability, complexity, compatibility, relative advantage, and observability, covering a period from 2014 to 2020. The study used a concurrent mixed-methods approach to ensure both quantitative and qualitative aspects of the study were considered, given the complexity of the inquiry. The study used purposive sampling to select 4 districts in Zambia: Choma, Petauke, Chongwe, and Mumbwa using the standard sample size table provided by Sekeran (2003), which provided for a sample size of 1024 at a concentration of 0.035 with an accuracy level of 95% confidence. The farmers were interviewed using structured questionnaires. An IBM statistical analysis in social science (SPSS) was used to analyze quantitative data, and thematic analysis was used to analyze qualitative data. From the study 50.82% of the farmer's said WII is not consistent with the p-value of 0.001, which was significant, and further, 40.8% of the farmers indicated the importance of bundling the services to have relative advantages of the product with a p-value of 0.001. 47.87% of farmers indicated they were not satisfied with the payout system, with a p-value of 0.001, which was significant. The study concluded that paying attention to the innovation characteristics as suggested by the diffusion innovation theory by Rodgers is important and that the theory can extend its views by considering the functionality of the market. Farmers do not adopt innovations at the same time, which has practical ramifications for the study's findings.
