Cuiaba: UFMTc1995  ap. 156.  aAceitação de sistemas de policultivo pelo produtor: Land use in the Amazon region by the indigenous populations was ecologically appropriate, but inappropriate in the general sense of sustainability, resulting in economic hardship for the people concerned. Modern agricultural practices (monocultures), for their part, have led to a series of failures. Successful agricultural activity in Amazonia calls for more complex systems that improve nutrient recycling and reduce the loss of plant material. In this context, agroforestry systems can rehabilitate traditional, indigenous practices by optimizing land use and satisfying basic human needs without destroying natural resources, and improving them where possible. The poster analyses the possible contribution of mixed cropping systems. Because of the similarities to the production systems encountered in Amazonia, mixed cropping systems may become more attractive to the local population to the extent that they prove to be flexible, sustainable and economically viable in practice. Their acceptance, adoption and use by farmers will help to alley general concerns, and improve overall prosperity and security.  aenvironmental degradation  amixed cropping  amultiple cropping  aAgricultura Sustentável  aCultivo Multiplo  aFloresta Tropical Úmida  aRecuperação do Solo  aAgrofloresta  aAgroforest  aAmazonas  aArea degradada  aBrasil  aManaus  aReclamation  aSustainability  aTropical rain forest
