Resumo: Drought affects several parts of the globe and causes negative social, economic and environmental effects. The aim of this study was to assess the performance of the Standardized Vegetation Index (PVI) obtained from the NDVI (Normalized Difference Vegetation Index) for ten days of SPOT-Vegetation satellite, for monitoring drought in northeast Brazil based on the historical series from 1998 to 2012. In order to verify the results, rainfall data obtained from the TRMM satellite (Tropical Rainfall Measuring Mission) from March 2011 to March 2012 was standardized. As of December 2011, it was observed that rainfall was below normal for most of the northeast, resulting in a decrease in IVP for the entire area under study. Factors such as positioning of the Intertropical Convergence Zone and El Niño influence rainfall in the region. The results are satisfactory, indicating the occurrence of severe drought in Northeast Brazil since January 2012. IVP variability was observed along with delay in vegetation response to rainfall estimates based on the TRMM. The analyses confirmed that the IVP was efficient for drought monitoring in northeastern Brazil.

O objetivo deste estudo foi avaliar o comportamento do Índice de Vegetação Padronizado (IVP), obtido a partir do produto NDVI (Normalized Difference Vegetation Index) decendial do satélite SPOT-Vegetation, para o monitoramento da seca no nordeste brasileiro, a partir da série histórica de 1998 a 2012. Para subsidiar os resultados foi realizada a padronização dos dados de precipitação obtidos do satélite TRMM (Tropical Rainfall Measuring Mission), de março de 2011 a março de 2012. A partir de dezembro de 2011, observa-se que a precipitação ficou abaixo do normal na maior parte do nordeste brasileiro, acarretando diminuição do IVP em toda a região estudada. Fatores como o posicionamento da Zona de Convergência Intertropical e El Niño influenciaram no regime de chuvas da região. Os resultados são satisfatórios, indicando a ocorrência de intensa seca no nordeste brasileiro, sendo observada variabilidade do IVP e defasagem na resposta da vegetação à precipitação estimada a partir do TRMM. As análises comprovam que o IVP mostrou-se eficaz no monitoramento das secas na região nordeste do Brasil.Universidade Federal de Viçosa - UFV2014-07-02info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufv.br/reveng/article/view/41110.13083/reveng.v22i3.454Engineering in Agriculture; Vol. 22 No. 3 (2014); 211-221Revista Engenharia na Agricultura - REVENG; v. 22 n. 3 (2014); 211-2212175-68131414-398410.13083/reveng.v22i3reponame:Engenharia na Agriculturainstname:Universidade Federal de Viçosa (UFV)instacron:UFVporhttps://periodicos.ufv.br/reveng/article/view/411/297Leivas, Janice FreitasAndrade, Ricardo GuimarãesVictoria, Daniel de CastroTorresan, Fabio EnriqueBolfe, Edson Luisinfo:eu-repo/semantics/openAccess2023-01-19T13:21:50Zoai:ojs.periodicos.ufv.br:article/411Revistahttps://periodicos.ufv.br/revengPUBhttps://periodicos.ufv.br/reveng/oairevistaengenharianagricultura@gmail.com||andrerosa@ufv.br||tramitacao.reveng@gmail.com|| reveng@ufv.br2175-68131414-3984opendoar:2023-01-19T13:21:50Engenharia na Agricultura - Universidade Federal de Viçosa (UFV)false
