This study aims to show how the integration of passive and active learning approaches contributes towards the significant understanding of problems associated with sustainable development. To do this, a case study from the municipality of San Miguel de Achiutla in Oaxaca, Mexico, is used as a general method, with the specific procedure including an instrument based on secondary sources representing the passive learning phase, as well as an instrument created on the basis of primary sources, designed in relation to the active learning component. The passive learning phase enabled us to identify variables pertaining to the highly vulnerable dimensions of sustainable development, and to also detect areas in which there is a deficit of information, since not all data are available, while the active learning phase revealed the causes of vulnerability from the perspective of different agents, including those who experienced the issues directly. In view of the above, we conclude that rather than being exclusive, these two different approaches should in fact be complementary.
