Abstract

O presente estudo tem como objetivo analisar espacialmente os dados de produtividade agrícola. Através da estatística espacial é possível estimar alguns parâmetros do semivariograma relevantes para estudar o problema do risco sistêmico, com implicações nos programas de seguro agrícola. Em particular estimou-se os parâmetros de alcance, para se verificar a distância, na qual a correlação espacial tende a zero. Para a análise empírica, utilizou-se dados de produtividade agrícola municipal do IBGE, para a soja e milho, no estado do Paraná, no período de 1990 a 2002. O estudo mostrou que de fato a dependência espacial destes dados existe, tornando-se praticamente nula à distâncias relativamente longas (em km) e pode ser captada em todos os anos, para ambas as culturas.
