This type of agriculture has been criticized because it results in emission of large amounts of carbon into the atmosphere and a loss of soil productive potential. Since 1991, Project SHIFT-Tipitamba has researched this type of agriculture and, in a subsequent phase, attempted to propose solutions that could be adopted in northeastern Pará, a region of ancient colonization in Amazon and highly anthropized based on an exclusively slash-and-burn agricultural system for more than 100 years. This paper presents some results obtained over two decades of research on these agricultural systems and proposes a method for the recovery or maintenance of the productive potential of these areas based on sequential agroforestry with secondary vegetation management and chop-and-mulch land preparation.  aAgroforestry  aAmazonia  aShifting cultivation  aSoil conservation  aStubble Mulching  aConservação do solo  aAgricultura sem queima  aAmazon  aDerruba-e-queima  aSistema agroflorestal  aSlash-and-burn1 aKATO, O.
