Question

Determine the historical change in primary sector

Answer 1

Answer:

The primary sector of the economy includes any industry involved in the extraction and collection of natural resources; such as farming, forestry, mining and fishing.

The primary sector tends to make up a larger portion of the economy in developing countries than it does in developed countries. For example, animal husbandry is relatively more common in countries in Africa than it is in Japan.[need quotation to verify]

Mining in 19th-century South Wales provides a case study of how an economy can come to rely on one form of activity.

In developed countries primary industry has become more technologically advanced - witness for instance the mechanization of farming as opposed to hand-picking and -planting. More developed economies may invest additional capital in primary means of production. As an example, in the United States' corn belt, combine harvesters pick the corn, and sprayers spray large amounts of insecticides, herbicides and fungicides, producing a higher yield than is possible using less capital-intensive techniques. These technological advances and investment allow the primary sector to employ a smaller workforce - in this way, developed countries tend to have a smaller percentage of their workforce involved in primary activities, instead having a higher percentage involved in the secondary and tertiary sectors.
