This paper assesses the impact of rice research on household food security in Tanzania. The adoption of research-based innovations in rice farming, on which the impact of rice research is assumed to depend, is outlined. Rice production and consumption levels are presented. The paper shows that farmers produce rice for meeting a range of livelihood outcomes, including food security. However, meeting household needs such as education, health and building good houses are as important as food security. In this context, it is argued that food security should be understood within the framework of household livelihood strategies rather than being seen as dependent on household rice production.
