Instabilidade Temporal na Produção Agrícola Familiar de Sequeiro no Semiárido do Nordeste Brasileiro

The objective of this study is to estimate temporal instabilities associated to harvested area, yield per hectare, production value, and production per person of bean, cassava and corn which are the principal food crops in family farms in semiarid municipalities of Ceará and Rio Grande do Norte Sta...
