Os danos ambientais causados pelo processo de erosao do solo podem seragrupados em dois conjuntos de efeitos: internos (on site) e externos (off site) a area de producao agricola. Este trabalho objetiva a obtencao do valor economico de ambos os efeitos ambientais. Utilizaram-se os efeitos nos sistemas de geracao de energia eletrica, como base de avaliacao dos efeitos externos, e a perda dos nutrientes do solo nas estimativas dos efeitos internos. Utilizou-se o metodo do custo de reposicao e da producao sacrificada para calcular o valor monetario do dano ambiental interno e externo na bacia hidrografica do rio Sapucai. O valor economico do dano ambiental externo mostrou ser de expressiva grandeza a taxa de desconto de 3% a.a., correspondendo ao custo equivalente anual de US$ 9.854.480,00. Por outro lado, os valores anuais dos custos internos, impostos pela erosao do solo agricola, situaram-se por volta de US$ 5.377.913,00. As estimativas anualizadas dos custos externos correspondem a, aproximadamente, o dobro dos custos internos. |

Ancient anthrosols known as Amazonian dark earths or terra preta are part of the human built landscape and often represent valuable landscape capital for modern Amazonian populations in the form of fertile agricultural soils. The fertility, resilience, and large stocks of carbon in terra preta have inspired researchon their possible role in soil fertility management and also serve as an example for a growing biocharindustry it is claimed will sequester carbon for climate change mitigation. Although there is considerablescientific and public interest in terra preta there is still much debate and little concrete knowledge of the specific processes and contexts of its formation. Research indicates that the formation of terra preta occurred mainly in midden deposits, themselves patterned around habitation areas, public areas, and routes of movement. Data from topographic mapping, soil analyses, and excavations in three regions of Amazonia demonstrate a widespread pattern of anthrosol formation in ring-shaped mounds surrounding flat terraces that extend across large areas of prehistoric settlements. It is hypothesized that there is a widespread type or types of occupation where the terraces were domestic areas (houses or yards) surounded by refuse disposal areas in middens which built up into mounds over time, forming large deposits of terra preta and creating what could be called a middenscape. Initial results support the hypotheses, showing the interrelationship of residential and public areas, anthrosols, routes of move- ment, and natural resources. The patterning of anthrosols in ancient settlements indicates the use of space and can therefore serve as a basis for comparison of community spatial organization between sites and regions.
