A landscape appears to be nothing more than a random ensemble of plains, valleys, hills, forests, and bodies of water. The disarray has a hidden meaning; it is not a juxtaposition of various physical forms, but rather the coming together in one place of an organized milieu and ecology. Social anthropologist Carlos Fernandez II has shown, on the basis of various studies of Palawan Province, that behind the appearance of chaos presented by the itinerant agriculture of tribal groups lies a concealed order. The scattered arrangement of cultivated plots, the different forms of human association for purposes of cultivation, the variety of patterns of distribution, exchange and consumption represent close adaptation to ecological, social and economic possibilities. The landscape is thus a nexus of relationships.
