The purpose of this piece of work is to investigate, through a literature review, the role of intermediaries in agricultural and rural development. In the first place, a general view of the roles of intermediaries, (focusing on the two main types of intermediaries, i.e. facilitators and brokers), as depicted in literature, is provided. Following, the emergence of facilitators and brokers in agricultural literature is explored based on the turn from reductionist to systemic science as well as from the expert syndrome to participatory development.
