Pampa Iluga. Technologies, labor, and persistence of an agricultural prehispanic landscape in the Atacama Desert (50 BC - AD 1800)

In this paper, we critically discuss the direct and absolute relationship that has been established in the Andes between agro-hydraulic development, social complexity, and centralized power, based on the archaeological and ethnographic evidence related to agricultural and hydraulic features preserved in Pampa Iluga (Tarapaca, Chile), particularly around the Iluga Tumulos site. Our analysis brings up to date a material and historical memory, challenging the classical vision that has underestimated the role of corporate work and decentralized community organizations. This is consistent with current perspectives that view these organizations as agents of change, capable of developing their own large-scale, long-term agricultural projects, as has been the case in the hyperarid lowlands of the Atacama Desert. Complementarily, these memories allow us to high-light the ontological dimension of this indigenous agriculture, granting agency to other non-human entities with whom humans are closely intertwined and coordinated in the construction of this Tarapacan landscape. This creates an intricate socio-natural and temporal assemblage in which any attempt to separate nature from culture is a fruitless task.
