The main goal of this practice, led by Extituto with support from organizations like Delibera Brasil and Democracia en Red, was to generate a multi-stakeholder participatory process to address the issue of solid waste management in Buenaventura, a city marked by deep inequalities, forced displacement, and structural violence. The assembly emerged as the culmination of five years of territorial work and was inspired by deliberative methodologies developed in Latin America. The practice combined regional learning with local knowledge, recognizing Buenaventura’s own deliberative traditions. A multi-stakeholder roundtable was formed, bringing together community leaders, private sector representatives, and decision-makers. This table co-designed and tested training and deliberation methodologies with a territorial lens, ensuring that outcomes were locally grounded and could be appropriated by community organizations.
