<p>It is said that the Amazon rainforest receives <a href="https://en.wikipedia.org/wiki/Amazon_rainforest#History">up to half of its nutrients</a> via <a href="https://en.wikipedia.org/wiki/Mineral_dust">mineral dust from the Sahara desert</a>. But a few thousand years ago, the <a href="https://en.wikipedia.org/wiki/Neolithic_Subpluvial">Sahara desert was much more fertile</a>, having a savannah-like environment.</p>

<p>Did this mean that the nutrient transfer to the Amazon did not take place during this time? If so, what did the Amazon look like?</p>

# What was the Amazon like during Green Sahara?

(Asked by: username_0 on 2014-10-02)

It is said that the Amazon rainforest receives [up to half of its nutrients](https://en.wikipedia.org/wiki/Amazon_rainforest#History) via [mineral dust from the Sahara desert](https://en.wikipedia.org/wiki/Mineral_dust). But a few thousand years ago, the [Sahara desert was much more fertile](https://en.wikipedia.org/wiki/Neolithic_Subpluvial), having a savannah-like environment.

Did this mean that the nutrient transfer to the Amazon did not take place during this time? If so, what did the Amazon look like?

[Here](https://www.nature.com/articles/s43247-020-00071-w) is a brand new (January 2021) study from Nature.

It proposes that the Sahara has not been the main source of dust for the Amazon for the past 7,500 years of Holocene, but rather dust from North and South Africa, the Andes, and Southern South America.
