Resumo
We present an analysis of the income variation of castor bean producers in the
Microregion of Irecê -BA and Meso-region Sertões Cearenses, respectively, in the
period from 2000 to 2015. We aimed to evaluate several indicators within the PNPB
associated to socioeconomic attributes (price, yield and area) and its contribution to
gross income variation of castor bean producers in these regions; and to explain the
dynamics of competition for agricultural area in the PNPB context, related to the castor
bean crops in the refions that took part of the research. We used shift-share as an
empirical strategy, assessing the role of Price, Income and Area to measure the effects
of the gross income variations. We also identified whether the Price Effect have caused
impacts on food security, by means of the scale and substitution effects. The results
showed that the Yield Effect was the major responsible for the variation of the gross
income of the castor bean producers in the Irecê-BA. As for the Meso-region Sertões
Cearenses - CE, negative Income effect and positive Area were the must important to
gross income sources. Results also pointed out that food crops were replaced by nonfood
crops in Irecê, but this was not the case in the Sertões Cearenses.
