Lands in south-central Chile, long thought to have been marginal until the Spanish conquest, are here shown to have been developing complex societies between at least AD 1000 and 1500. Part of the motor was provided by coastland cultivation on raised platforms, here identified and surveyed for the first time. The authors date the field systems and suggest that they were introduced by farmers from the north seeking wetlands in the face of increasing aridity in the central Andes and southern… 

Ecological engineers ahead of their time: The functioning of pre-Columbian raised-field agriculture and its potential contributions to sustainability today

The need to reconcile food production, ecosystem services and biodiversity conservation has spurred the search for more sustainable ways of farming. Archaeology offers examples of prehistoric

Wetland Raised-Field Agriculture and Its Contribution to Sustainability: Ethnoecology of a Present-Day African System and Questions about Pre-Columbian Systems in the American Tropics

One adaptation for farming wetlands is constructing raised fields (RF), i.e., elevated earth structures. Studies of RF agriculture have focused mostly on the vestiges of RF that were cultivated by

A Holocene history of monkey puzzle tree (pehuén) in northernmost Patagonia

Although it is established that climate and fire have greatly influenced the long‐term ecosystem dynamics of Patagonia south of 40°S, the environmental history from northernmost Patagonia (37–40°S),

Pre-Columbian Earthworks in Coastal Amazonia

TLDR
Pre-Columbian inhabitants of the Guianas coast carefully organized, managed and “anthropisized” their territory following a specific pattern.

An insight into pre-Columbian raised fields: the case of San Borja, Bolivian lowlands

Abstract. Pre-Columbian raised field agriculture in the tropical lowlands of South America has received increasing attention and been the focus of heated debates regarding its function, productivity,

Thinking Outside the Continent and Outside the Box: Cross-Continental Comparative Studies Can Enrich Studies of Pre-Columbian Raised-Field Agriculture

Abstract. Despite an attempt at intercontinental synthesis by Denevan and Turner (1974) almost 50 years ago, studies of agricultural raised fields (RF) in the Neotropics and in Africa and New Guinea

Recent Landscape Archaeology in South America

South American archaeologists use the term landscape to analyze a broad range of relationships. Examples include intensive agriculture and political power, myth and place, and climate change and

Climate change and cultural resilience in late pre-Columbian Amazonia

TLDR
It is proposed that societies with intensive, specialized land-use systems that relied primarily on polyculture agroforestry, resulting in the formation of enriched forests and fertile Amazonian dark earth in the long term, were more resilient to climate change.

Aboriginal Drained-Field Cultivation in the Americas

TLDR
The three main types of land reclamation in aboriginal America were irrigation, terracing, and drainage, which was practiced in varied environments, including high-land basins, tropical savannas, and temperate flood plains.

TLDR
The findings contribute to debates on human carrying capacity, population size and settlement patterns, anthropogenic impacts on the environment, and the importance of indigenous knowledge, as well as contributing to the pride of place of the native peoples in this part of the Amazon.

Evidence for cultivar adoption and emerging complexity during the mid-Holocene in the La Plata basin

TLDR

Long-Term Aridity Changes in the Western United States

TLDR
Using gridded drought reconstructions that cover most of the western United States over the past 1200 years, it is shown that this drought pales in comparison to an earlier period of elevated aridity and epic drought in AD 900 to 1300, an interval broadly consistent with the Medieval Warm Period.
