In 2012, I participate in a preliminary survey for the Ayahuasca National Inventory of Cultural References (INRC). The INRC consists of a set of technical products that support the application for registration of a cultural asset of an immaterial nature. The following products were delivered to the executor: (1) Indigenous uses and knowledge about ayahuasca in Acre, MARTINI, 2012a, 33p; (2) Indigenous use, vine and other [autonomous] uses of ayahuasca, 2012b, 30p; (3) List of bibliographic references on indigenous issues in the INRC of Ayahuasca, 2012c, 16p; (4) Bibliographic records on indigenous issues from the INRC of Ayahuasca, 2012d, 15p; (5) Preliminary completion of cultural property forms referring to the sixteen indigenous groups of Acre; 2012, 80p. The reports and the process as a whole can be consulted at IPHAN headquarters in Rio Branco, Acre.
