Agribusiness participation in Brazil generates investments in rural infrastructure and employment, with direct effects on local quality of life. In this sense, government policies to support the production of ethanol from sugarcane and to promote bioelectricity from bagasse production have made Brazil a country of world leadership in this field. This paper reports an assessment of socioeconomic impacts due to sugarcane production in three regions in Brazil (Piracicaba, Presidente Prudente and Southwest Goiás). Local quality of life is defined as five dimensions: income and inequality, education, infrastructure, health and general development, analysed using panel data modelling, with variables that could explain differences in development due to local characteristics, including sugarcane activity. Presidente Prudente has the highest levels of progress in education, poverty, infrastructure and general development indicators. The models indicate that participation of sugarcane has positive impacts on the indicators of the microregion. In case of Piracicaba microregion, in two models (''L-Theil'' and ''Illiteracy rate'') indicators related with sugarcane sector are significant explanatory variables, contributing for better indicators. Finally, Southwest Goias-where sugarcane activity develops later-is the single microregion in which the adjusted models have no significant explanatory variables related to sugarcane sector.
A Floresta Tropical Atlântica representa o maior remanescente florestal do Estado de Santa Catarina. Observa-se, entretanto, um incremento no índice de desmatamento, tendo como resposta governamental, exigências de se manejar sustentadamente os recursos florestais. Este trabalho pretende lembrar que no processo decisório o manejo de rendimento sustentado pode ou não ser atrativo. Conclui-se que o modelo atual de sustentabilidade falha ao tentar promover o local, com clareza de objetivos, afirmando-se que aqueles que geram benefícios ambientais não devem assumir sozinhos os custos desta produção. Palavras-chave: manejo florestal, política ambiental, economia ecológica, análise custo/benefício. ABSTRACT ATLANTIC TROPICAL FOREST. A study for sustainable development . The tropical Atlantic Forest represents the biggest remaining of the Santa Catarina state forest, although it is observed in the increasing index of deforest having as government response, an exigency of sustainable management of the forest resources. This paper wants to remember that in the decision process the management of the sustainable income may not be attractive. It is concluded that the today's sustainable model lacks when tries to promote the localized, with clear objectives, assuming that those which generates environment benefits shall not assume the costs of this production itself.
