Ancient Andean agricultural landscapes have been the subject of a large number of archaeological and agro-ecological studies, which generally refer to regions with favourable environmental conditions or, in the case of arid and semi-arid environments, those with irrigation facilities. The aim of this article is to present and analyse the pre-Hispanic rain-fed farming systems widely represented in two adjacent regions of Bolivia’s arid and cold southern Altiplano. The search for archaeological agricultural areas combined aerial analysis and field surveys. Agro-ecological characterisation was based on historical and ethnographic studies of the region’s present-day populations. Despite their geographical proximity, similar environmental conditions, and same agropastoral way of life, the typology of cultivated areas developed in the southern altiplano differs significantly. Within this same framework of adaptation and resilience, the sectorisation of agricultural systems observed in these two regions reveals a regional productive specialisation that favoured internal exchanges and exchanges with other regions. These differences are related to two models of non-centralised, low-inequality societies—one strongly based on cohesion and the other characterised by greater fragmentation and social conflict—underlining the limits of strict environmental determinism in shaping agricultural landscapes. These results provide new food for thought in the debate on the use and value of rain-fed agricultural practices and more broadly on the diversity of adaptations by human societies in extreme and unstable environmental contexts.

This article shows a set of agroecological practices that were incorporated into the archeological landscape of the Chanchán basin by pre-Hispanic Kañaris societies for 1200 years (240–1438 AD), a millennium before the arrival of the Incas, and that continue to be used in this landscape by certain indigenous communities of the 21st century. The use of archeobotanical techniques, contrasted with ethnobotanical sources, has allowed us to interpret how these societies structured their cultivation systems, agroecological practices, and landscape management, for the conservation of agroecosystems in the western Andean foothills. Agroecological legacies show how the stability, adaptability, and elasticity of Andean agriculture can be sustained under models of progressive intensification without this causing irreversible environmental damage in the agroecosystems. Kañaris agroecological practices configured the Chanchán landscape as a great cultural artifact, wherein the non-human agency of plants (cultivated and wild) was more than a mere adaptation to the niches culturally constructed by human populations. Non-humans are active subjects in recovering the functional and structural integrity of agroecosystems after a social or ecological disturbance. All this is part of landscape management based on an “Ecological Diversification Model”, where plant species are adapted to the ecotones and ecological floors of the western Andean foothills, to diversify and increase the availability of food crops that are bioculturally appropriate given the present agrobiodiversity.
