O custo social do desmatamento da Amazônia brasileira: o caso da castanha-do-brasil ( Bertholletia excelsa )

Este trabalho trata do desmatamento na Amazonia brasileira com enfase no custo social imposto a nacao pela reducao e perda da base florestal, em especial da castanha, um dos principais produtos nao madeireiros da floresta, no periodo de 1998 a 2008. Para medir os custos sociais do desmatamento que recaem sobre os produtores e consumidores de castanha-do-brasil, utilizou-se o conceito de excedente economico de Marshall. O custo social medio anual estimado foi da ordem de 11,6 milhoes de reais, recaindo, em media, 63 % desses custos sobre os produtores e 37 % sobre os consumidores. Portanto, todos perdem com os danos causados a base florestal e ao ecossistema da floresta tropical.

Demanda dos Estados Unidos por carvão vegetal brasileiro

O objetivo do trabalho e identificar quais variaveis afetam a demanda dos Estados Unidos da America pelo carvao vegetal brasileiro e estimar as elasticidades das mesmas. O estudo utiliza o metodo dos minimos quadrados ordinarios (MQO), optando pela forma funcional logaritmica, pela simplicidade em obter as elasticidades, e adota o nivel de significância de 5%. Os dados foram obtidos junto ao FAS e ao BEA em periodo trimestral e corrigidos pelo IPC dos EUA. O modelo ajustado, embora tenha apresentado um baixo coeficiente de determinacao (R2), nao apresentou maiores problemas estatisticos e econometricos. Os resultados indicaram que a demanda dos EUA por carvao brasileiro pode ser explicada pelas expectativas dos consumidores, preco do carvao brasileiro e pela renda norte-americana. Os precos de bens relacionados do Mexico e da Argentina nao foram significativos a 5% de probabilidade, indicando que o carvao desses paises nao sao bons substitutos ao produto brasileiro.

Influência da Klabin no mercado de madeira em tora do estado do Paraná

A Klabin e a maior empresa de base florestal do Estado do Parana. A ela pertence nao somente a maior parte dos reflorestamentos do Estado, como tambem a responsabilidade pela maior oferta de madeira para o processamento mecânico e o maior consumo de madeira fina do Parana. Essas caracteristicas conferem a empresa grande poder de mercado e capacidade de influenciar na formacao do preco da madeira. Este trabalho aborda a influencia da Klabin na formacao do preco da madeira no Parana. Como base metodologica, empregou-se o teste t de Student para comparar o preco da madeira para celulose e o processamento mecânico dentro e fora da regiao de atuacao da Klabin no ano de 2008. Os resultados nao indicaram uma diferenca entre os precos nas regioes analisadas que pudesse ser justificada pelo poder de oligopolio e oligopsonio da empresa, ou seja, a empresa possui poder de mercado, mas nao o utiliza.

Determinantes da situação do egresso de gestão ambiental da Universidade de Brasília – UnB (Determinants of the graduates situation from the environmental management by University of Brasilia - UnB)

Although enrollment in the last decade in higher education has doubled, productivity recorded by workers in Brazil remained stable, suggesting a low effectiveness of the knowledge acquired by Brazil universities. The University of Brasilia (UnB) has expanded its number of vacancies through the creation of new campuses on the periphery of Brasilia city, for example, the creation of the UnB Faculty of Planaltina (FUP). The FUP was opened in 2006 and offers courses of the Agribusiness Management, Environmental Management, Degree in Natural Sciences and Rural Education. The Environmental Management course (EM) of FUP is new and untraditional, raising the importance of evaluation. Thus, the study aimed to analyze the influence of the academic activities from EM course at employability of its egress, as well as, the interference of these activities in the decision of the former student continue your study. To this end, questionnaires were given to the egress from the EM course of FUP, reaching a sample of 44 forms returned. Among the results highlighted the positive influence of professional internship for the insertion of graduates in the labor market and scientific 1 Professor da Faculdade UnB de Planaltina, Universidade de Brasília (FUP/UnB).

Efetividade da compensação ambiental monetária no Brasil

In Brazil, monetary environmental compensation occurs in situations in which a project environmental impact cannot be avoided or mitigated, resting to the entrepreneur an obligation to support the implementation and maintenance of a Protected Area. The criteria for choosing the area to be benefited are related to spatial and functional connection with the same. This study aimed to evaluate the effectiveness of monetary environmental compensation, evaluating the spatial and functional connection in the application of the instrument resources. Under these circumstances we assessed if resources generated from environmental compensation tend to be applied in the project site, as well as, if the affected areas benefited belong to the same biome. Results indicated that monetary environmental compensation does not usually occur in the project nearby area; however, in 96% of cases it tends to occur in the same biome.

Determinantes para um Sistema de Informação Florestal

Determinants for a forest information system. This paper tests the relative importance of a group of pre-selected themes for the construction of a Forestry Information System for Brazil – BR-SIFLOR. The methodology that was used lies on a set of 12 thematic modules and 58 sub-themes in order to be evaluated by a group of people (holistic judging method). The information relates to: 1) Forest cover; 2) Production Forests; 3) Ownership of Forest Lands; 4) Forest-based Industry; 5) Forest Products Market; 6) Technology Products; 7) Forest Biological Diversity; 8) Climate Change and Forest; 9) Forest Economics and Statistics; 10) Forest Law; 11) Forest Certification; 12) Forestry Teaching and Research. We conclude that the key information to be included in the SIFLOR focus on themes of Forest Economy and Production.
