The shared management initiative of the Metropolitan State Forest in Paraná, Brazil, establishes a pioneering model of co-management between the Instituto Água e Terra (IAT) and the local indigenous community. Formalised in 2022, this agreement allows 35 indigenous people to remain in the conservation unit, guaranteeing their right to use the territory under a sustainable management plan. Activities include reforestation with native species, environmental education, responsible tourism and community policing. This approach strengthens ecological and social resilience, promoting the conservation of the Atlantic Forest biome while valuing indigenous culture and traditional knowledge.
