As a comprehensive treatment of these dis- tinctive anthropogenic soils has never been published, we decided to select papers from these symposia and develop an edited volume.

It developed with two symposia on Amazonian dark earths that were held in 2001 in conjunction with the Conference of Latin Americanist Geographers in Benicassim, Spain, and the Congress of the Brazi- lian Archaeological Society in Rio de Janeiro, Brazil, respectively, and culmi- nated at the First International Workshop on Terra Preta Soils held in Manaus and Santarem, Brazil, in July 2002.
