In the study of the environmental changes due to human activities, it is very important to clarify the detailed processes on the progress of settlement and land use in the semi-arid regions corresponding to the marginal zone for stable agriculture. Human activities in the marginal zone are influenced by even slight changes in the physical environment, and on the other hand the physical environment is also influenced by the impact of man. In the hundreds of Pekina and Black Rock Plain, the study area, the sale of land began in August 1873, and the settlement in the early years, 1873-1877, was advanced with amazing rapidity. The standard allotment was 640 acres (1 mile^2, 259 ha) to each settler. But its area was not enough to maintain stable agriculture in the semi-arid region of South Australia. Consequently many settlers had to abandone their lands. Since the first settlement the holder of land has changed many times because of severe droughts. But the new farming system called "ley farming" was introduced in the 1930s and farmers were able to maintain their lands.
