| Abstract: | The Puna is an arid region running along the Andes mountains, more than 3600 m above sea level. Overgrazing has severely degraded much of this ecosystem, and this has dramatically reduced agricultural production and resulted in poverty for human inhabitants. Llamas are native to the Puna and are well suited to live there. Their grazing habits and digestive system make efficient use of native forages, and their padded feet keep soil disturbance to a minimum, thereby reducing erosion. Uncontrolled llama breeding over the last 500 years has degraded the quality of the fiber they produce, so today it is generally of low quality. Analysis of llama fibers obtained from two production regions of Argentina showed that some llamas possess sufficiently fine mean fiber diameters (less than 23 μm if guard hairs are excluded) to allow their fleeces to be sold at a premium. A higher price would make llamas more attractive to raise than the goats and sheep commonly found in the Puna today. Switching to llama production would increase grower income and sustainability of agriculture in the region. |
