| A cultura da banana está presente em todos os estados brasileiros, sendo a fruta com maior volume de produção após as frutas cítricas. Planta de demanda hídrica relativamente elevada, a bananeira desempenha papel preponderante na maioria dos perímetros irrigados no Nordeste do Brasil, incluindo a região do Submédio São Francisco. A obtenção de altas produtividades da cultura, com a qualidade da fruta conforme demandas dos mercados, exige o uso de técnicas adequadas e a atenção especial dos produtores em todas as fases do seu cultivo. Ciente disso, a Embrapa Mandioca e Fruticultura, situada em Cruz das Almas, BA, em parceria com a Embrapa Semiárido, localizada em Petrolina, PE, elaborou este sistema de produção para a cultura irrigada da bananeira no... |

| La question des plantations en Afrique au XIXè siècle s'insère dans le grand cadre de l'histoire universelle. Ce cadre était déterminé par les nouvelles exigences du marché mondial, notamment des pays industialisés d'Europe occidentale et des Etats Unis d'Amerique. Les paysans africains s'étaient mis à produire pour ce marché mondial. Ils fournissaient pas un véritable travail de plantation, mais plutôt d'entretien. Certains produits comme le caoutchouc, recueilli à partier des .. sauvages, étaient uniquement destinés à l'exportation, tandis que le maïs, le copra, le coton, et l'arachide ... |

| Soil samples were collected from the top 7.5 cm of soil in a Strict Natural Reserve (SNR), a surrounding buffer zone, a cassava farm and matured plantations of Gmelina, teak, and pine, so as to determine if plantation establishment and intensive cultivation affect the density and diversity of soil mites. Altogether, 41 taxonomic groups of mites were identified. The diversity and densities of mites in within the SNR, the buffer zone and the Gmelina were more than the diversity and densities in the cassava farm, teak and pine plantations. Each plantation had its own unique community structure which was different from the community structure in the SNR plot. The SNR plot and Gmelina were dominated by detritivorous cryptostigmatid mites unlike teak and pine... |

| Unlike other resources such as petroleum, coal, and copper, forests are renewable. Yet, in many respects forests historically have been treated as a nonrenewable resource in that forest stocks were depleted or "mined" and loggers moved on to exploit other "deposits." The lands were often put to other uses, typically agricultural, or allowed to regenerate naturally. This paper looks at technical change in forest extraction, i.e., logging under a number of different conditions. It finds that, on average, labor productivity has been increasing in recent decades. However, total factor productivity in the US has declined in recent years. In addition, the study examines the tree-growing potential of plantation forestry. It finds that there is underway a... |

| Vast areas of Brazil are being planted to Eucalyptus in order to provide renewable sources of timber, charcoal and cellulose. Although the rapid growth and productivity of various Eucalyptus species undoubtedly relaxes the pressure on logging of native forests, there are ecological costs. Firstly, some eucalypt species are vulnerable to pest outbreaks. A large number of native Lepidoptera, Coleoptera and leaf-cutting ants (Atta spp.), some of which have become pests, have been found on eucalypts growing in Brazil. Probably, the diverse myrtaceous flora of South America supports a fauna that can adapt to the introduced Eucalyptus species. Secondly, the leaf litter produced under Eucalyptus plantations differs substantially from that of native forests both... |
