Such units operate on a region characterized by heavy constraints in tenns of soil and water resources. The production systems show a low technological pattem, in sufficient to achieve an appropriate standard of living for the farmer, and, to avoid the continuous deterioration of the natural resources, mainly of the caatinga vegetation. Some studies have shown that the subsistence type of agriculture today practiced, only is successful on three in every ten years, and that livestock production, by its lower vulnerability to drought effects, has constituted the main anti-migration factor in the semi-and region. Results of a recent study conducted by Embrapa Semi-Arid workers, including small farms of 107 counties, confrrmed that trend, showing a gross income increase as livestock participation in the farm activities becomes higher. Research on livestock Production in Nontheast has generated a vast number of technologies, which, if adequately combined and operated, can assure, with no environrnental damage, economical levels of productivity and a more equitable distribution of the benefits.  aAnimal production  afarming systems  aCaatinga  aProdução animal  aSistema de Produção  aVegetação  aRegião semi-árida  aSemi-arid region  aSustainability  aSustentabilidade1 aGUIMARÂES FILHO, C.1 aSA, I.
