ANÁLISE DA INFLUÊNCIA CLIMÁTICA SOBRE A CULTURA DO MILHO NA REGIÃO METROPOLITANA DE MACEIÓ (AL)
Abstract
The State of Alagoas has a small participation in Brazilian agricultural production of maize, however, because of its location and other factors, some municipalities are greatly affected by statistics, soon local production may suffer falls caused by years of activity of El Niño and La Niña, thus succeeding socioeconomic problems for a population. Thus, the objective of this research is to analyze the effects of climate influence on maize crop grown in the Metropolitan Region of Maceió (RMM) and for this the precipitation data from the National Institute of Meteorology (INMET) and the Agency Nacional de Águas (ANA) were used, from 1987 to 2017. Used Matlab software to generate a Wave Analysis, such as what are the possible identifications of statistical causes of extreme events for the metropolitan region (Maceió, Marechal Deodoro and Rio Largo). Corn data were extracted from the Brazilian Institute of Geography and Statistics website, from 1987 to 2017. These data were generated maps of spatial distribution of corn production in years of extreme weather events. It can be concluded that corn production in the region was influenced differently by the El Niño and La Niña phenomena in their categories, but was noted in all municipalities of RMM, but there was no corn production in the El Niño low years, and there was an increase in corn production in La Niña strong years.
