英文摘要	The objective of this study was to analyze the dynamics of land use and land cover by linking it to economic variations in the municipalities of Castelo do Piaui and Juazeiro do Piaui. The analysis of the land use and land cover dynamics was based on the Landsat 5 TM satellite imagery analysis, which showed that there was a reduction of the Arborea Caatinga and agricultural ranching (crop, livestock and vegetal extraction) and class increase classes Shrub Caatinga. The reduction in tree savanna is the result of i) an increase of temporary crops by 50% from 1997 to 2009 and ii) increase in coal extraction and burning, respectively, 18.2% and 4.4%, from 2004 to 2009. Possible stages of ecological succession and increased shrub savanna are due to i) increase in the areas intended for permanent crops at the rate of 18.5%; ii) reduction of beef cattle, sheep and goats by 2.4% in 1997 and 2009, and iii) the decrease in mineral production. Social data reveals need for investments in health, job creation, and especially in education due to their low level of education.
