Pre-Columbian farmers of the Neotropical lowlands numbered an estimated 25 million by 1492, with at least 80 percent living within forest biomes. It is now well established that significant areas of Neotropical forests were cleared and burned to facilitate agricultural activities before the arrival of Europeans. Paleoecological and archaeological evidence shows that demographic pressure on forest resources—facilitated by anthropogenic burning—increased steadily throughout the Late Holocene… 

Neotropical human–landscape interactions, fire, and atmospheric CO2 during European conquest

Neotropical biomass burning reconstructions synthesized from soil and sedimentary charcoal records indicate a period of reduced biomass burning sustained for several centuries after ~500 cal. yr BP.

Fire-free land use in pre-1492 Amazonian savannas

A high-resolution 2,150-y paleoecological record from a French Guianan coastal savanna is reported that forces reconsideration of how pre-Columbian savanna peoples practiced raised-field agriculture and how the CE impacted these societies and environments.

Pre-Columbian land use in the ring-ditch region of the Bolivian Amazon

The nature and extent of pre-Columbian (pre-AD 1492) human impact in Amazonia is a contentious issue. The Bolivian Amazon has yielded some of the most impressive evidence for large and complex

Fire history across the Little Ice Age in southern Pacific Costa Rica

We present two high-resolution records of Late Holocene (Meghalayan) fire history from lakes in the lowlands of southern Pacific Costa Rica and compare them with evidence of pre-Columbian agriculture

2,100 years of human adaptation to climate change in the High Andes

High-resolution fossil pollen, charcoal, diatom and sediment chemistry data from the iconic archaeological setting of Laguna de los Condores, Peru are used to reconstruct changing land uses and climates in a forested Andean valley and do not support the idea that forest regrowth and peak carbon sequestration were coincident with European arrival.

Pre‐Columbian ring ditch construction and land use on a ‘chocolate forest island’ in the Bolivian Amazon

We present a palaeoecological investigation of pre‐Columbian land use in the savanna ‘forest island’ landscape of the north‐east Bolivian Amazon. A 5700‐year sediment core from La Luna Lake, located

Did pre-Columbian populations of the Amazonian biome reach carrying capacity during the Late Holocene?

Different proxies for relative population change between 1050 BC and AD 1500 within this broad region are presented and it is demonstrated that this aggregate scenario shows considerable variability when projected geographically, highlighting significant gaps in archaeological knowledge yet also providing important insights into the resilience of past human food procurement strategies.

Long-term perspective on wildfires in the western USA

Sedimentary charcoal accumulation rates are used to construct long-term variations in fire during the past 3,000 y in the American West and compare this record to independent fire-history data from historical records and fire scars, which show a forest “fire deficit” attributable to the combined effects of human activities, ecological, and climate changes.




Abstract The corpus of historical data from lake sediments relating to the climate, vegetation, and human land use of the lowland Central American tropical forest between ca. 20,000 BP and the time

Pre-Columbian land-use history in Costa Rica: a 3000-year record of forest clearance, agriculture and fires from Laguna Zoncho

We analysed pollen and charcoal in a lake-sediment core from Laguna Zoncho, a small mid-elevation lake in southernmost Costa Rica. The record provides evidence of 3000 years of human occupation,

The analysis shows that the forest biome in most parts of Amazonia appears to have been remarkably resilient to climatic conditions significantly drier than those of today, despite widespread evidence of forest burning.

Evidence for Forest Clearance, Agriculture, and Human-Induced Erosion in Precolumbian El Salvador

Abstract It is now well established that Precolumbian farmers of Mexico and Central America were responsible for widespread environmental degradation before the arrival of Europeans. Relatively

A Holocene record of Neotropical savanna dynamics from El Salvador

The historical ecology of the Ahuachapan savanna is reconstructed from a 4.83-m sediment core from Laguna Llano del Espino, Ahuachapan, western El Salvador. Stable carbon isotopes (δ13C), pollen, and

Fire, climate change and biodiversity in Amazonia: a Late-Holocene perspective

An analysis of Amazonian soil carbon records reveals that the records have distinct spatial and temporal patterns, suggesting that either fires were only set in moderately seasonal areas of Amazonia or that strongly seasonal and aseasonal areas are undersampled.

Changes in fire regimes since the Last Glacial Maximum: an assessment based on a global synthesis and analysis of charcoal data

Fire activity has varied globally and continuously since the last glacial maximum (LGM) in response to long-term changes in global climate and shorter-term regional changes in climate, vegetation,
