Our research was based on two projects: “Assessment of the impact caused by the Oga’i project on the Mbya-Guaraní communities. Inhabitability and surroundings” (2015-2017) and “Territorial empowerment of the Mbya-Guaraní Community through the assessment of the impact caused by the Oga’i project on the tekohá guasú Keri” (2017-2018), both of which have been backed by the Co-Operation Office of the University of Seville and involved the collaboration of the Faculty of Architecture, Design and Art (FADA) of the National University of Asunción of Paraguay, and the NGO named Centro de Desarrollo y Hábitat (Cedes-Hábitat), along with the invaluable contributions of Sara Benítez Méndez in helping to comprehend and engage with the community.
