Heterogeneidade espacial da produção de leite em Pernambuco

Abstract

The research aimed to: 1) assess the descriptive statistics related to the variables that influence the value of milk production in the municipalities of the state of Pernambuco in the years 2006 and 2017; 2) assess the spatial instabilities of rainfall, temperatures and the variables that define the value of milk production in the municipalities; 3) assess the interaction between the variables that influence the value of milk production with the respective rainfall patterns; 4) assess whether there were differences in the variables studied in milk production and climate variables. The data came from the 2006 and 2017 Agricultural Censuses and NOAA. We selected 60 municipalities that were the largest producers in 2017 and were benchmarks in 2006. Descriptive statistics were estimated for the following variables: number of lactating cows, productivity and milk prices, as well as rainfall observed in 2006 and 2017. The synergy between these variables was analyzed using the spatial heterogeneity index created in the research, using factor analysis. The differences in the means of the variables between the years were verified using paired means tests. The results showed that production is more heterogeneous in the largest producers. Production, production value, productivity and milk prices had higher averages in 2017.
