The information on risk preferences and risk perceptions among maize far mers in maize highly growing highlands is limited. Similarly, relationships be tween socio-demographic factors and risk preferences are not clearly ex plored. A risk game with pay-offs and a hypothetical scenario in a survey question naire were performed to assess the risk preferences of maize farmers in m a ize - growing regions of the Southern and Northern highlands of Tanzania. Risk ranking was executed during focus group discussions and revealed that risk perceptions of maize farmers varied across gender and location. Cross-sectional data on farmers’ and farms’ characteristics including risk scenarios from an Agronomic Panel Survey (APS) of the 2016/2017 growing season was col lected from 560 Household Heads (HHs), randomly selected within a spatial sampling frame. The study recommends the inclusion of risk preferences and risk perceptions status of farmers in policy-making and the introduction of new agricultural technologies in order to foster a high adoption rate and ad vancement of agricultural development.
