Sheep farming
Sheep farming introduced in the late 19th century has been a principal economic activity. After reaching its heights during the First World War, the decline in world wool prices affected sheep farming in Argentina. Nowadays, about half of Argentina's 15 million sheep are in Patagonia, a percentage that is growing as sheep farming disappears in the pampas to the north. Chubut (mainly Merino) is the top wool producer with Santa Cruz (Corriedale and some Merino) second. Sheep farming revived in 2002 with the devaluation of the peso and firmer global demand for wool (led by China and the EU). Still, little investment occurs in new abattoirs (mainly in Comodoro Rivadavia, Trelew, and Rio Gallegos), and often phytosanitary restrictions reduce the export of sheep meat. Extensive valleys in the Cordilleran range have provided sufficient grazing lands, and the low humidity and weather of the southern region make raising Merino and Corriedale sheep common.
