Abstract Despite today?￠????s widespread reference to sustainability, initiatives are still quite incipient. Ecovillages are communities that carry out an array of sustainable practices and aim to influence society as models for alternative lifestyles. The goal of this paper is to analyze the meanings associated with these communities in the academic literature and their relevance to sustainability debates. Regardless of the conceptual imprecision of the term ?￠????ecovillage?￠???? and important challenges and limitations regarding their social role in society, ecovillage initiatives (many that are educational) have propagated by diffusing alternative ideas and practices throughout society. They are increasingly linked with other movements and social institutions, functioning as key nodes in sustainability-oriented networks. As they promote concrete actions in the construction of societal alternatives, ecovillages significantly contribute to efforts of rethinking sustainability.
