Innovation by ancient farmers to improve soil fertility continues to have an impact on the biodiversity of the Amazon, a major new study shows.

Early inhabitants fertilized the soil with charcoal from fire remains and food waste. Areas with this “dark earth” have a different set of species than the surrounding landscape, contributing to a more diverse ecosystem with a richer collection of plant species, researchers from the State University of Mato Grosso in Brazil and the University of Exeter have found.

The legacy of this land management thousands of years ago means there are thousands of these patches of dark earth dotted around the region, most around the size of a small field. This is the first study to measure the difference in vegetation in dark and non-dark earth areas in mature forests across a region spanning a thousand kilometers.

The team of ecologists and archaeologists studied abandoned areas along the main stem of the Amazon River near Tapajós and in the headwaters of the Xingu River Basin in southern Amazonia.

Lead author Dr Edmar Almeida de Oliveira  said: “This is an area where dark earth lush forests grow, with colossal trees of different species from the surrounding forest, with more edible fruit trees, such as taperebá and jatobá.”

The number of indigenous communities living in the Amazon collapsed following European colonization of the region, meaning many dark earth areas were abandoned.

The study, published in the journal Global Ecology and Biogeography, reveals for the first time the extent to which pre-Columbian Amerindians influenced the current structure and diversity of the Amazon forest of the areas they once farmed.

Researchers sampled around 4,000 trees in southern and eastern Amazonia. Areas with dark earth had a significantly higher pH and more nutrients that improved soil fertility. Pottery shards and other artefacts were also found in the rich dark soils.

Professor Ben Hur Marimon Junior, from the State University of Mato Grosso, said: “Pre-Columbian indigenous people, who fertilized the poor soils of the Amazon for at least 5,000 years, have left an impressive legacy, creating the dark earth, or Terras Pretas de Índio

Professor José Iriarte, an archaeologist from the University of Exeter, said: “By creating dark earth early inhabitants of the Amazon were able to successfully cultivate the soil for thousands of years in an agroforestry system

“We think ancient communities used dark earth areas to grow crops to eat, and adjacent forests without dark earth for agroforestry.”

Dr Ted Feldpausch, from the University of Exeter, who co-authored the study with Dr Luiz Aragão from the National Institute for Space Research (INPE) in Brazil, said: “After being abandoned for hundreds of years, we still find a fingerprint of the ancient land-use in the forests today as a legacy of the pre-Colombian Amazonian population estimated in millions of inhabitants.

“We are currently expanding this research across the whole Amazon Basin under a project funded by the UK Natural Environment Research Council(NERC) to evaluate whether historical fire also affected the forest areas distant from the anthropogenic dark earths”.

Many areas with dark earth are currently cultivated by local and indigenous populations, who have had great success with their food crops. But most are still hidden in the native forest, contributing to increased tree size, carbon stock and regional biodiversity. For this reason, the lush forests of the “Terra Preta de Índio” and their biological and cultural wealth in the Amazon must be preserved as a legacy for future generations, the researchers have said. Areas with dark earth are under threat due to illegal deforestation and fire.

 “Dark earth increases the richness of species, an important consideration for regional biodiversity conservation. These findings highlight the smallscale longterm legacy of preColumbian inhabitants on the soils and vegetation of Amazonia,” said co-author Prof Beatriz Marimon, from the State University of Mato Grosso.

April 22 (UPI) — Analysis of ancient pottery fragments suggest groups of hunter gatherers living in the Baltic had developed culturally distinct cuisines between 6,000 and 7,500 years ago.

Researchers collected hundreds of fragments from pottery vessels found at 61 different archaeological sites in the Baltic region. Scientists analyzed the fragments for evidence of the purpose and contents of the ancient vessels.

Their findings — published this week in the journal Royal Society Open Science — suggests different groups of prehistoric humans evolved unique culinary traditions, cooking and combining foods in distinctive ways.

“People are often surprised to learn that hunter-gatherers used pottery to store, process and cook food, as carrying cumbersome ceramic vessels seems inconsistent with a nomadic lifestyle,” lead study author Harry Robson, archaeologist at the University of York in Britain, said in a news release. “Our study looked at how this pottery was used and found evidence of a rich variety of foods and culinary traditions in different hunter-gatherer groups.”

Scientists found little evidence of ceramic vessel use for non-food purposes, like making resin. Instead they found a diversity of culinary practices, even among groups with access to similar resources. The evidence suggests cultural practices, not variations in food availability, dictated the differences in how and what different groups cooked and ate.

“Our study suggests that culinary practices were not influenced by environmental constraints but rather were likely embedded in some long-standing culinary traditions and cultural habits,” said co-author Blandine Courel, scientist at the British Museum.

Researchers found evidence that hunter-gatherers in the Baltic were taking advantage of a wide variety of foods, including marine fish, seals, beavers, wild boar, bear, deer, freshwater fish, hazelnuts and plants. Some groups were also consuming dairy.

“The presence of dairy fats in several hunter-gatherer vessels was an unexpected example of culinary ‘cultural fusion,'” Robson said. “The discovery has implications for our understanding of the transition from hunter-gatherer lifestyles to early farming and demonstrates that this commodity was either exchanged or perhaps even looted from nearby farmers.”

Pottery usage and the development of culinary traditions has previously been linked to the spread of agriculture across Europe, but the latest research — made possible by improved molecular and isotopic analysis techniques — suggests groups of hunter-gatherers had developed similar levels of culinary sophistication and diversity.

“Chemical analysis of the remains of foods and natural products prepared in pottery has already revolutionized our understanding of early agricultural societies, we are now seeing these methods being rolled out to study prehistoric hunter-gatherer pottery,” said Oliver Craig, study co-author and University of York archaeologist. “The results suggest that they too had complex and culturally distinct cuisines.”
