“…In short, these discussions of the mechanisms associated with the human acquisition of knowledge about the natural world seem to have led to an increasing emphasis on the conditions-material (ecology and modes of production), socio-political (political economy) and symbolic-cognitive (local forms of representation)-into which the processes of transmission (D'ANDRADE, 1981;HEWLETT and CAVALLI-SFORZA, 1986;OHMAGARI and BERKES, 1997;ROSS, 2002a;ROSS and REVILLA-MINAYA, 2011) and distribution (GARRO, 1986;BOSTER, 1986;ROMNEY and MOORE, 1998;REYES-GARCIA et al, 2007a) of knowledge are inserted. Taking into consideration the abovementioned research contributions, and considering that rural/local populations have undergone significant economic and socio-cultural changes all over the globe, studies have increasingly focused on the transformations of local knowledge associated with this process (ZENT, 1999;HUNN, 1999;BENZ and WORTH, 2000;ROSS, 2002b;ELLEN, 2006;REYES-GARCIA et al, 2007b).…”
