Through a cross-sectional and comparative approach, this contribution aims to study the different experiences that have marked the process of tunisian local Agendas 21 during the period of 2000-2011. It tries to reposition projects in the logic of the stakeholders involved in the fabric of local Agendas 21. The balance sheet drawn up through various projects will be, then, returned to the cross-thematic of local participatory initiatives and the role of the local Agendas in the territorial prospecting. This central question would be repositioned in a context of social revolution and of legitimacy crisis, whose effects have hit full force, from 2011, the representative and the decision-making of tunisian cities structures.
