This study shows a stratigraphic analysis with emphasis on the coal-bearing strata of the Early Permian package in southernmost Brazil (Paraná Basin). The studied interval comprises the Early Permian lithostratigraphic units Harare, Rio Bonito, Palermo and Irati (base). Eight facies associations are recognized, and are presented within a third order stratigraphic framework, linked by systems tracts, limited by flooding surfaces and sequence boundaries. Some of the South-Brazilian coal seams were originated in fluvial settings, but the most important coals were deposited in a lagoon-barrier system.
A profunda crise estrutural que afeta o setor da pesca artesanal pode ser vista como uma das inúmeras contradições do estilo de desenvolvimento adotado em nosso País. Esta crise tende a se agravar no bojo da globalização assimétrica, desafiando um sistema rígido, centralizado e tecnocrático de gestão de recursos naturais de uso comum. O artigo focaliza as oportunidades e bloqueios à re-criação deste sistema, com base nos avanços da pesquisa ecológico-humana e nos princípios do ecodesenvolvimento.
Nº 14-abril de 2009 maneuvering that has been created, within the current scenario of economic and cultural globalization, for the definition of alternative public policies inspired in principals of sustainable rural development. This article is an attempt to meet this demand, presenting a synthesis of the partial results reached through a joint French-Brazilian research project financed by the CAPES-CONFECUB Agreement. The text provides an exploratory contribution for our understanding of the challenges that surround the definition of a new style of development for the state. Furthermore, it identifies a range of emerging initiatives that can serve as a point of reference for plans for rural sustainable development for the next few years.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
