Considering the agroclimatic and social diversity of Mexico, this paper starts by recognizing the potential of rural extensionists within a policy framework of agroecological transition in the country. This paper identifies the types of productive positioning (agroecological vs. conventional) of rural extensionists located across the diverse states and socioeconomic regions of Mexico. This data is intended to outline particular features for the differentiation and targeting of regional strategies to train extensionists according to their regional context. We analyzed 1448 questionnaires gathered in 2019 via the online platform SurveyMonkey from rural extensionists enrolled in the Mexican Rural Extension System (SERMexicano). The results revealed that extensionists mainly identified themselves with the agroecological model. However, a significant proportion across states and regions still associated themselves with the conventional model. Three types of trends were recognized in relation to the positioning of extensionists, namely agroecological, towards neutrality, and contrasting. According to the socioeconomic regions where extensionists are located, diverse inter- and intraregional nuances among these positionings were also identified. Finally, we conclude by emphasizing the need for this heterogeneity to be considered in order to design and implement programs aimed at transitioning and expanding agroecology in Mexico.
