The Tarímiat Pujutaí Nuṉka Reserve, one of the largest nature reserves in the Amazon region, was created in Morona Santiago, Ecuador. Its name, which in the Shuar language means “territory for well-being”, reflects the deep connection between the indigenous communities and their environment. This achievement is the result of an extensive participatory process of conservation and environmental management, promoted by the provincial government in alliance with four indigenous organisations (FICSH, NASHE, NAE and PSHA) and supported by Nature and Culture International. Through 21 meetings – workshops, meetings and assemblies – and with the participation of 893 people, a normative framework was collectively developed that integrates the indigenous cosmovision and financial mechanisms for sustainability while strengthening community participation and environmental protection.
