ABSTRACT
Pampas means plains in the native Quechua dialect. Pampas indeed is a vast fertile low land plain. Pampas spreads into 7,50,000 km2 (289,577 miles2) zone between latitudes 28ºS and 39ºS, and longitudes 50-65ºW. It encompasses parts of southern tip of Brazil, entire Uruguay and Central to North-eastern parts of Argentina covering provinces such as Buenos Aires, La Pampas, Santa Fe and Cordoba (Figure 3.1). Majority of the plains region occurs in Argentina and Uruguay. Pampas are interrupted by low mountain ranges such as Sierra de laVentana north of Bahia Blanca. These hill ranges are about 1,300 m.a.s.l. River Platta is the major water drainage system of the Plains region. It irrigates expanses in the Cardoba, La Pampa, and Buenos Aires provinces. Rivers Salado, Parana, and Uruguay too supply irrigation water to natural prairies and cropland. Rivers such as Colorado and Negro are excellent water resources to famers in southern Pampas. Pampas region is drier in the west and it becomes progressively wetter and humid as we traverse east to the Atlantic coast.
