ABSTRACT
Clearly, the Tiwanaku polity transformed profoundly after AD 800. In Katari, major settlements such as Lukurmata and Qeyakuntu experienced decreasing residential density just as monumental construction ceased and associated ritual activity declined. Simultaneously, specialized storage complexes in Lukurmata, in tandem with an increasing intensity of raised field production in the Koani Pampa, highlight an increasing concern with the production, distribution, and storage of cultivated goods. Associated with raised field systems in the Koani Pampa were numerous canals, dikes, and other hydrological features. It is likely that most were built or enlarged at this time to form a linked, integrated system dedicated to the production of tubers and quinoa on fieldbeds while fostering ideal microenvironments for lake birds and aquatic resources in intervening swales (Kolata 1986).
