The mountainous slopes are covered with stone-lined terraces, boundary walls, and canals. In the early 1980s I began a study of one abandoned farming system, raised field agriculture. The goal of the investigation was to describe; map; date origins, use, and abandonment; and determine the functions,
carrying capacity, and sustainability of raised field agriculture. Raised fields (Spanish: camellones; Quechua: waru waru; Aymara: suka kollus) are elevated planting platforms of earth (1 to 20 meters wide, 10 to hundreds of meters long, and 0.5 to 1 meter high). Adjacent to each platform are canals that provided the earth for construction. My Peruvian colleagues and I estimate that raised fields cover more than 120,000 hectares of the Lake Titicaca basin, most of which now lie abandoned (Fig. 3). Archaeological excavations of raised fields demonstrated that farmers began constructing them by 1000
B.C. The production from raised fields and other intensive forms of agriculture underwrote the complex societies that developed within the basin.
