This chapter explores the transformative potential of “planning from below” in the Haitian urban context, where institutional frameworks often ignore or marginalize local knowledge. It analyzes how community actors reclaim the right to narrate, design, and shape their territories through collective practices of mapping, storytelling, and participatory planning. These grassroots initiatives challenge top-down models by situating urban governance within the lived realities of residents, acknowledging informality not as a deficit but as a resource for creativity and resilience. Through co-design processes, citizens articulate spatial imaginaries that reflect their social, cultural, and economic priorities, thereby generating new forms of legitimacy and territorial recognition. The chapter emphasizes that while these practices provide pathways toward more inclusive governance, they confront barriers such as asymmetrical power relations, mistrust of authorities, and the absence of mediating institutions. Yet, by fostering dialogue and collective intelligence, planning from below opens possibilities for rethinking urban governance as a shared endeavor. It argues that co-design is not simply a method of participation but a political act that redefines planning as deliberation, negotiation, and recognition of plural territorial sovereignties.
