Milk production systems in Southern Brazil

Abstract The aim of this study was to verify the dynamics of milk production in Southern Brazil, analyzing the spatial distribution, evolution and structure of bovine milk production systems in the dairy-specialized microregions. To this end, annual data from 2000 to 2015 are drawn from the Municipal Livestock Survey, reported by the Instituto Brasileiro de Geografia e Estatística, and the Programa Nacional de Fortalecimento da Agricultura Familiar, reported by the Banco Central do Brasil. Location quotient analyses, principal component analyses and clustering analyses are applied. Results of the location quotient analysis indicate that, of the 94 microregions in Southern Brazil, 36 are specialized in milk production. Two principal components were identified (mechanized production and family production) capable of explaining 78.3% of the variation in the data. Among microregions specialized in milk production, cluster analysis identifies four groups that are differentiated by productivity levels and predominance of family versus commercial production. Furthermore, results reveal that there is substantial heterogeneity among microregions specialized in bovine milk production in Southern Brazil.
