Agroecology has been addressed as one of the most prominent alternatives to achieve sustainability in agriculture, both for land and people. For this reason, academics, authorities, social leaders and organizations from many fields have urged a transition from modern conventional to agroecological agriculture. However, farms are complex systems, and this transition demands the transformation of a broad set of characteristics and practices that are a consequence of the farm administrator decisions. These are, in turn, conditioned by its specific context (social, educational, economic, political). Therefore, a clear understanding of the main drivers behind the management of farms is vital for supporting an effective transition, where the process remains stable and does not return to the previous state (conventional production) or reaches an alternative state (permanent degradation). For this reason, this research evaluated the Main Agroecological Structure (MAS) of 20 farms in different degrees of agroecological transition, in five locations of the northern-central Andean region of Ecuador. The farms had a moderately developed structure on average (71.05 over 100), and MAS variation was significantly related to the study site. One of the main differences between sites was a more extended prevalence of cooperation and development programs. For this reason, the author proposes that MAS measurements should be complemented with deeper analyses of the capacity-building background of each site. This study aims to establish a baseline of the MAS in Ecuador, and to provide new tools for monitoring agroecological transition.
