To ensure the inclusion of ecovillages located in diverse geographical, economic and social contexts, we included in our sample countries with the highest and lowest GDP per capita levels, which had at least six ecovillage registered in the GEN international database. This database is based on self-identification, allowing ecovillages and similar initiatives to register themselves. Moreover, the database is not constantly updated. Consequently, there are projects in the database that do not exist anymore, or that do not meet our selection criteria. A total of 36 countries were included in the the sampling (21 from the Global South and 15 from the Global North), from which we received responses from ecovillages in 30 countries. This country selection allowed us to compare diffusion activities between ecovillages located in the Global North and in the Global South.
