Unfortunately, little has been written about the AWÁ and their culture. The best resource is in Spanish. It is a book by Benhur Ceron Solarte called LOS AWÁ-KWAIKER.
As I mentioned yesterday, some of the hardest hit by the drug/guerrilla violence are those of indigenous communities. Unfortunately, the reservations where the Awá live are also located in areas where poppy and coca are grown. Thus making it ground zero for the FARC / Paramilitary / Army war.
