Primary sector of the economy
The primary sector of the economy includes all industry involved in the extraction as well as production of raw materials, such as farming, logging, fishing, forestry as alive as mining.
The primary sector tends to gain up a larger item of the economy in developing countries than it does in developed countries. For example, in 2018, agriculture, forestry, as well as fishing comprised more than 15% of GDP in sub-Saharan Africa but less than 1% of GDP in North America.
In developed countries the primary sector has become more technologically advanced, enabling for example the mechanization of farming, as compared with hand-picking and -planting in poorer countries. More developed economies may invest additional capital in primary means of production: for example, in the United States corn belt, combine harvesters selection 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, so developed countries tend to throw a smaller percentage of their workforce involved in primary activities, instead having a higher percentage involved in the secondary and tertiary sectors.
