Resumo: The aim of this study was to estimate climate change impacts on irrigation water demand for permanent crops. The PRECIS (Providing Regional Climates for Impact Studies) system was applied, and downscaling techniques were used at the river basin level, with the boundary conditions of the regional climate model (HadRM3P). A climate data set was generated for 1961 to 1990 (baseline) and for future climate projections. The regional geographical coordinates were considered for interpolation in a georeferenced coordinated system. The reference evapotranspiration was estimated through data of monthly average temperature. Projected climate change increased projected irrigation water demand, because evapotranspiration was estimated to increase by 3.1 to 2.2% and rainfall was estimated to decrease by 30.9 to 37.3%. The 2040 water need was estimated to increase by 32.9% to 43.9%, according to the analyzed scenario.

Foi empregado o sistema integrado de modelagem regional PRECIS ("Providing Regional Climates for Impact Studies"), e aplicado o método de redução de escala de bacia hidrográfica, com as condições de contorno do modelo climático regional (HadRM3P). Foi utilizado um conjunto de climatologia de base do modelo de 1961 a 1990 e de projeções climáticas futuras. As coordenadas geográficas da região em estudo foram consideradas para interpolação num sistema de informação geográfica. A evapotranspiração de referência foi estimada por meio de dados da temperatura média mensal. As mudanças climáticas projetadas aumentaram a demanda projetada de água para irrigação, porque a evapotranspiração foi estimada para aumentos de 3,1 a 2,2% e a precipitação pluvial foi estimada para diminuições de 30,9 a 37,3%. O aumento da necessidade hídrica foi estimada em 32,9% a 43,9%, para o ano de 2040, conforme o cenário analisado.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraEmbrapa Macroprograma 2Gondim, Rubens SonsolCastro, Marco Aurélio Holanda deEvangelista, Sílvio Roberto de MedeirosTeixeira, Adunias dos SantosJúnior, Sérgio César de França Fuck2009-01-06info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/1312Pesquisa Agropecuaria Brasileira; v.43, n.12, dez. 2008; 1657-1664Pesquisa Agropecuária Brasileira; v.43, n.12, dez. 2008; 1657-16641678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/1312/5572https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/1312/919info:eu-repo/semantics/openAccess2014-07-29T17:54:18Zoai:ojs.seer.sct.embrapa.br:article/1312Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-07-29T17:54:18Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
