A implantação de florestas cobrindo extensas areas florestais no Brasil a partir de 1966, com o advento dos incentivos físcais e do programa nacional de papel e celulose, tem mobilizado elevado contingente de mao-de-obra. A evasão do homem do campo atraído por melhores salários oferecidos pelas empresas urbanas, tem criado sérios problemas para a manutenção dos povoamentos implantados. O uso de herbicidas é uma alternativa válida para substituir a mão-de-obra rural nos trabalhos de limpeza de áreas florestais. Visando solucionar problemas de tratos culturais em áreas de florestas plantadas, foi instalado o presente ensaio, cujos objetivos foram determinar o efeito do DCPA e Oryzalin no teor de N,P,K, Ca e Mg em folhas de Eucalyptus saligna Smith; b. observar a eficiência de níveis de dosagens dos produtos citados no controle de plantas daninhas da cultura incial de Eucalyptus saligna Smith... |

The Amazon is the largest tropical forest area on Earth, and has been undergoing rapid deforestation for the last four decades. In the Brazilian Amazon, large-scale pasture for cattle ranching and soybean production are the main land uses, leading to a yearly deforestation rate of 0.5%. These conversions are mostly located in frontier areas distributed along the so-called ?arc of deforestation?. Within this large zone, various land use change processes are interacting through several modes of land valuation and organisation. From several case studies in the State of Pará (Brazil), the current project aims at analysing how landscape dynamics are related to infrastructure development, ecological conditions, zoning policies and to the evolution and the organisation of the production, consumption and marketing chains of livestock products. This paper presents the results for one test site, the region of São Félix do Xingú, South of Pará. This region is the focus of land speculation, cattle expansion, and deforestation. Road construction, investments in electrical energy, financial credit for cattle, and the land reform policies have all fuelled this process. All these factors make this region one of the most dynamic agricultural frontiers in the Brazilian Amazon. The main objective of the paper is to improve our understanding of deforestation processes by crossing spatial analyses and livestock economics studies, and to characterise the role and impact of various natural and anthropic factors in the location and development of the main types of farmers, and their policy implications.
