Title A name given to the resource O Papel das Oleaginosas em um Cenário de Mudanças Climáticas no Semiárido Brasileiro (The Role of Oilseeds in a Climate Change Scenario in the Brazilian Semiarid) Creator An entity primarily responsible for making the resource João Nildo S. Vianna, Marcelo Castro Pereira, Laura M.G. Duarte, Magda E. Wehrmann Description An account of the resource Este trabalho tem por objetivo avaliar, ainda que de forma preliminar, os efeitos limitantes das mudanças climáticas na produção de oleaginosas agro-energética no semiárido brasileiro, nomeadamente a redução dos índices pluviométricos e aumento de temperatura. Para alcançar este objetivo usa-se como referência a evolução de variáveis climáticas, por meio da série histórica entre 1973 e 2010, e projeções futuras tendo por base os cenários de mudanças climáticas, desenvolvidos para o nordeste brasileiro até 2100. O recorte geográfico é a região de Irecê, no semiárido da Bahia, tradicional reduto da agricultura familiar e grande produtor de alimentos consorciado com oleaginosas. O estudo mostra que as culturas tradicionais de oleaginosas estão próximas aos limites de exigências hídricas, pelo que, para enfrentar as mudanças nos padrões climáticos, vai ser necessário um melhoramento genético das culturas tradicionais para que essa espécies consigam tolerar as restrições hídricas. Preconizando-se igualmente a introdução de espécies mais rústicas e com maior resistência ao estresse hídrico.

The study is based on the analysis of past climate, by evaluating a historic series of rain and temperature from 1973 to 2010. This historic series is, then, compared to a future climate prediction, based on climatic change scenarios developed for the Brazilian northeast until 2100. The geographic location of the study is the Irecê area of the State of Bahia, in the semi-arid northeast. That is a traditional family agriculture area with a strong food crop and oilseeds production. The study shows that traditional oilseed crops are being cultivated near the limits of their water needs. In order to face the climate changes, such crops would need to be genetically improved to increase their tolerance to water stress. An option would be to introduce species with higher level of tolerance to water stress. Keywords: family agriculture, vulnerability and adaptation to climate changes, biodiesel, semiarid.
