The fourth Sustainable Regency Festival was held from November 23-28 in two regencies simultaneously: Gorontalo and Bone Bolango. Themed “Rebuilding a Sustainable Identity,” the festival fostered collaboration among various stakeholders to make local wisdom the foundation of environmentally and socially sustainable development. Various engaging sessions, such as the Sustainable Chat, Sustainable Innovation Gathering, the Exploration of Sustainable Culture, and the Citizens’ Market, featured curated sustainable local products and local food. The Sustainable Regency Festival also served as a platform for finding solutions to challenges facing the host regencies.
