Micro-insurance can be an effective approach to smoothening income in adverse times and potentially a way to contribute to the financial inclusion of vulnerable populations. However, direct sales to individual smallholders remains a challenging task without an easily scalable solution. The current research seeks to find the determinants of adoption of a stand-alone coffee index-based insurance product in Uganda marketed by a farmer cooperative, and elicited preferences for improving the design and delivery model. A stratified household survey was conducted among 614 farmers, of which 40% adopted insurance and 62% were member of a farmer cooperative. In odds ratio terms, adopters perceived themselves to be 3.09 times more likely to receive a pay-out than non-adopters (P<0.01), and those having better access to extension services were 2.47 times more likely to adopt a policy (P<0.01). Yet farmers perceiving the design as complex were approximately half as likely to adopt (P<0.05). Farmers preferred the option of premium payments proceeds on delivery, mobile premium payments and delivering insurance through cooperatives/associations. Deepening insurance uptake among coffee farmers will therefore require a strong focus on communication and information sharing facilitated by cooperatives/associations (e.g. farmer cooperates, village and saving associations, or women’s associations).
