“…3 The semiarid economy is largely based on extensive forms of subsistence agriculture and cattle raising, with very low productivity and great dependence on weather fluctuations (Ab'Sáber (1999),Áridas (1995, SUDENE (1981), Áridas (1995), Cirilo (2008)). The region is also the driest in Brazil.…”

“…In Brazil, the semiarid region is mainly located in the northeast, covering approximately 800.000 km 2 (11% of the country's territory), with a typical Caatinga (dryland) vegetation, a seasonal xerophilous thorn woodland/shrubland, which prevails in the semi-arid lowlands on an extensive regional crystalline basement complex (Sampaio, 1995). The Brazilian semi-arid region is listed among the most densely populated semi-arid territories in the world (Ab'Saber, 1999;Figueirôa et al, 2006). The typical agricultural systems in this area are characterized by high grazing density, uncontrolled fire use, indiscriminate tree cutting (wood and charcoal production for industrial and domestic uses) and a fallow time that is typically shorter than is required to substantially enhance soil properties.…”

“…Além disso, correspondem a cerca de 40% da superfície da terra, compreendendo grande parte dos países pobres, agrícolas, com baixa renda per capita, ocupando na divisão internacional do trabalho o entreposto de celeiros agrícolas e fornecedores de matériaprima de ordem em geral, como o caso nacional. As similitudes das regiões semiáridas envolvem sempre aspectos climáticos, hídricos e fitogeográficos, como é passível de verificação a partir dos índices de umidade baixos; da escassez relativa de chuvas anuais; da irregularidade pluviométrica ao longo dos anos; dos longos períodos de carência hídrica; dos solos com problemas físicos e químicos, como os parcialmente salinos ou carbonáticos; e da ausência de perenidade fluvial, principalmente em relação às drenagens autóctones, conforme lembrado por Ab'Saber (1999).…”
