Resumo Avaliou-se o uso do solo e dos recursos florestais do bioma Caatinga no estado da Paraíba, de 1996 a 2018. Foram levantados dados da cobertura vegetal e das características dos recursos florestais e o seu potencial produtivo para a lenha e o carvão vegetal. As informações empregadas para caracterização do uso do solo e dos recursos florestais da Paraíba foram obtidas do Instituto Brasileiro de Geografia e Estatística (IBGE), do Ministério do Meio Ambiente (MMA) e da Associação Plantas do Nordeste (APNE). A pesquisa foi exploratória e os resultados apontam a existência de uma degradação contínua da cobertura vegetal, porém os tipos de uso do solo se modificaram ao longo dos anos estudados. Observou-se uma alteração no uso das terras da Paraíba com uma ampliação das áreas de matas/florestas e redução das áreas de pastagem. O carvão vegetal e a lenha foram os principais produtos do extrativismo. A Caatinga paraibana perdeu mais de 46% da sua vegetação, cerca de 2,40 milhões de hectares, mas observou-se o aumento do PMFS via adoção de políticas públicas e conscientização do mercado. As estimativas adotadas da cobertura vegetal e do uso do solo da Paraíba mostraram sensibilidade e elevado grau de risco à desertificação do bioma, necessitando de ações conjuntas permanentes que garantam o uso sustentável da biodiversidade. Conclui-se que a solução efetiva vem da conscientização e da prática do Plano de Manejo Florestal Sustentado no semiárido paraibano, proporcionando de forma mais eficaz a sustentabilidade do bioma Caatinga.

Abstract The use of soil and forest resources of the Caatinga biome in the state of Paraíbawas evaluated from 1996 to 2018. Data on vegetation cover and forest resource characteristics and their productive potential for firewood and charcoal were collected.The information used to characterize Paraíba’s land use and forest resources were examined by the Brazilian Institute of Geography and Statistics (IBGE), the Ministry of Environment of Brazilian (MMA) and the Northeast Plants Association (APNE). The research is exploratory and based on secondary data and may contribute, in part, to the economic development in the state. The results point to the existence of a constant degradation of the vegetation cover, although the types of soil use have changed over the studied years. The estimates adopted for vegetation cover and land use in Paraíba showed sensitivity and a high degree of risk to desertification of the biome, requiring permanent joint actions that guarantee the sustainable use of its biodiversity. It is concluded that the effective solution comes from the awareness and the practice of the Sustainable Forest Management Plan in the semi-arid region of Paraíba, providing more effectively the sustainability of the Caatinga biome.

The objective of this study is to analyze the competiveness of the Mato Grosso bovine meat in view of the international market through researching the factors that most influenced the performance of the Mato Grosso bovine meat exports from 1996 to 2010. Specifically, the aim was to verify if the Mato Grosso bovine meat contains competitive sustainable advantages to maintain its international market position and if it is possible to increase its market share. To do so, a comparison of the competitiveness of bovine meat export of Mato Grosso was performed. Also, the competitiveness of the Brazilian meat exports was compared with that of other main exporters of this product, namely, Australia, Argentina and the United States through the use of the Constant Market Share Model (CMS). The obtained results of CMS with respect to Mato Grosso made it possible to verify that competitiveness was not a dominant factor throughout the whole period and that Mato Grosso will be able to maintain its position in the world market and expand its market share further. These results are caused by the destination of the exports and the increase of global trade rather than competitiveness.
