Study: Centuries-Old Farming Methods Hold Key to Rainforest Conservation

From Voice of America:  Ancient Amazon farmers shunned slash-and-burn techniques



"The Amazon region of South America, the largest tropical rainforest and river basin on Earth, is disappearing at a rate of around 800,000 hectares a year, but a new study finds one possible strategy for reversing this trend in ancient Amazonian farming methods.
Analysis of a 1,000-year-old ecological record in the Amazon provides a rare glimpse at early farming practices before European explorers began arriving in the Americas more than 500 years ago. 

The study, published in Proceedings of the National Academy of Sciences, finds the ancient farming methods could slow the destruction of the Amazon rainforest.
he rapid expansion of agriculture and cattle ranching, road and dam construction, and illegal logging are the biggest drivers of this massive deforestation.  

Lead author Jose Iriarte, a paleoethnobotonist at the University of Exeter in England, focused on a coastal wetland savanna in present-day French Guyana, on South America’s northeastern coast, where ancient farm beds and canals remain, unaltered, on the landscape.  In pre-colonial history, Iriarte says, this was a period when farmers “reclaimed these seasonally flooded savannas into raised-field agricultural landscapes.”

A sediment core from the site provided the team with an unusually intact archive of how farmers farmed these fields. It shows pollen, plant species and charcoal before and after the European colonization in the late 15th and 16th centuries."
It is not surprising to us that ancient farming techniques could help solve the destruction of one of the world's great natural resources.  Proper care and use of the land, with a long-term goal of sustaining a local community, and jobs, and using ancient means of capturing and controlling rain, is coming full circle  both environmentally and economically.  Hopefully, regaining protection and vegetation of the forest.
