An in-depth study of the native groups of the Kariri and the Shoko of North-eastern Brazil examines a number of levels of their natural habitat. Indigenous knowledge and healing systems and how they have incorporated elements from other cultures are looked at, as well as the practical uses of local medicinal plants, and the economic and political strategies used for survival. This book really shows how a threatened minority can effectively help to shape its future and regain their ethnic identity and dignity.
