This study aims to explore how the Positive Deviance approach can be adapted to identify and prioritize rural development interventions for diverse farming households that pursue multiple objectives. We describe the adapted approach, consisting of three research steps, and a case study implementation in Tanzania. Based on this experience,  the potential of the Positive Deviance approach for household-specific prioritization of multi-objective development opportunities is discussed

Rural extension is a process of work and accompaniment with the producer aimed to sustainable development of their skills. In Mexico, a series of extension models have been adapted, that goes from the US, implemented in the early 1980’s, to the hub model or innovation node (platform - demonstration module - extension area) applied since 2010 under the MasAgro Program. The aim of this paper is to analyze the various processes of extension in Mexico.
