800-year-old farmers could teach us how to protect the Amazon
Date:4/9/2012

years and the ability to identify plants through there pollen, has allowed Power and this international team of scientists to document the types of crops and natural vegetation present thousands of years ago when raised-field farmers occupied the savannas of coastal French Guiana.

Secondly, the research in French Guiana contributes to an ongoing effort by Power and other international colleagues of building a global fire history database. This global database allows comparisons across continents, latitudes, longitudes and any area where the history of fire activity has been recorded. To date, nearly 1000 locations have been studied for their fire history. In the case of the French Guiana research, we found a pattern of increasing fire after 1500 AD, which is contrary to the robust patterns we have observed from over 300 charcoal records from the Americas that show decreasing fire at the same time.
