Farmers separate grains during a Quinoa harvest on a field in Tarmaya, some 120 km south of La Paz April 29, 2013. Still a nutritional staple for the indigenous people living in the Altiplano of Bolivia, Quinoa is also producing much profits for the region. The global boom for the golden grain, cultivated at high altitudes, has boosted prices five times in just nine years. Government officials hope $10 million in credits for producers will help boost production further still to meet the increasing demands at home and abroad.
