Descripción

Livestock grazing systems in true temperate zones (LGT) are most prevalent in Asia, with China and Mongolia having 60 percent of the agricultural land and 74 percent of the population in the LGT. There are also significant amounts of LGT pasture land in southern Argentina, northwestern United States, Canada, Turkey, and southeastern Australia (Table II.1). This AZ-LS category also represents significant portions of the total pasture land in several smaller countries, e.g., New Zealand and Chile. Agricultural lands are predominately pasture (only 7 percent arable) and relatively sparsely populated with 3.9 ha/capita overall. However, there is a great deal of variation in population density among countries such as China, Iran, Turkey, and Chile, which have densities of less than 2 ha/capita.
