Conteúdo: 	The soils predominating in the region are of a crystalline origin, normally flat, siliceous and stony, with low infiltration capacity and low organic matter content. Coupled with these characteristics, the high rainfall intensity causes water losses due to runoff and consequent water erosion. Given the characteristics of the region and when planning at farm levei, it is convenient to consider minimum risk mechanisms for exploitation which allow satisfactory production, despite the limiting environmental conditions. Various rainwater harvesting methods using animal traction as the power source have been developed and adopted through the work ofEMBRAPA, the Brazilian Enterprise for Agricultural and Livestock Research, based at CPA TSA, the Centre for Agricultural and Livestock Research in the Semi-Arid Tropics. The main rainwater harvesting techniques that have proven appropriate for the production conditions ofthe Braziliansemi-arid zone are presented in this chapter.
