Agrarian society in the context of "Hunter-gatherer"

Industrialisation (UK) or industrialization (US) is "the period of social and economic change that transforms a human group from an agrarian and feudal society into an industrial society. This involves an extensive reorganisation of an economy for the purpose of manufacturing." Industrialisation is associated with an increase in polluting industries heavily dependent on fossil fuels. With the increasing focus on sustainable development and green industrial policy practices, industrialisation increasingly includes technological leapfrogging, with direct investment in more advanced, cleaner technologies.

The reorganisation of the economy has many unintended consequences both economically and socially. As industrial workers' incomes rise, markets for consumer goods and services of all kinds tend to expand and provide a further stimulus to industrial investment and economic growth. Moreover, family structures tend to shift as extended families tend to no longer live together in one household, location or place.

Industrialization in the Soviet Union was a process of accelerated building-up of the industrial potential of the Soviet Union to reduce the economy's lag behind the developed capitalist states, which was carried out from May 1929 to June 1941.

The official task of industrialization was the transformation of the Soviet Union from a predominantly agrarian state into a leading industrial one. The beginning of socialist industrialization as an integral part of the "triple task of a radical reorganization of society" (industrialization, economic centralization, collectivization of agriculture and a cultural revolution) was laid down by the first five-year plan for the development of the national economy lasting from 1928 until 1932.

The People's Republic of Bulgaria (PRB; Bulgarian: Народна република България, НРБ, romanized: Narodna republika Bŭlgariya, NRB; pronounced [nɐˈrɔdnɐ rɛˈpublikɐ bɐɫˈɡarijɐ]) was the Bulgarian state existed from 1946 to 1990, ruled by the Bulgarian Communist Party (BCP; Bulgarian: Българска комунистическа партия (БКП)) together with its coalition partner, the Bulgarian Agrarian People's Union. Bulgaria was also part of Comecon as well as a member of the Warsaw Pact. The Bulgarian resistance movement during World War II deposed the Tsardom of Bulgaria administration in the Bulgarian coup d'état of 1944 which ended the country's alliance with the Axis powers and led to the People's Republic in 1946.

The BCP modeled its policies after those of the Soviet Union, transforming the country over the course of a decade from an agrarian peasant society into an industrialized socialist society. In the mid-1950s and after the death of Stalin, the party's hardliners lost influence and a period of social liberalization and stability followed under Todor Zhivkov. Varying degrees of conservative or liberal influence followed. After a new energy and transportation infrastructure was constructed, by 1960 manufacturing became the dominant sector of the economy and Bulgaria became a major exporter of household goods and later of computer technologies, earning it the nickname of "Silicon Valley of the Eastern Bloc". The country's relatively high productivity levels and high scores on social development rankings made it a model for other socialist countries' administrative policies.

Nomadic pastoralism, also known as nomadic herding, is a form of pastoralism in which livestock are herded in order to seek for fresh pastures on which to graze. True nomads follow an irregular pattern of movement, in contrast with transhumance, where seasonal pastures are fixed. However, this distinction is often not observed and the term 'nomad' used for both—and in historical cases the regularity of movements is often unknown in any case. The herded livestock include cattle, water buffalo, yaks, llamas, sheep, goats, reindeer, horses, donkeys or camels, or mixtures of species. Nomadic pastoralism is commonly practiced in regions with little arable land, typically in the developing world, especially in the steppe lands north of the agricultural zone of Eurasia. Pastoralists often trade with sedentary agrarians, exchanging meat for grains; however, they have been known to raid.

Of the estimated 30–40 million nomadic pastoralists worldwide, most are found in central Asia and the Sahel region of North and West Africa, such as Fulani, Tuaregs, and Toubou, with some also in the Middle East, such as traditionally Bedouins, and in other parts of Africa, such as Nigeria and Somalia. Increasing numbers of stock may lead to overgrazing of the area and desertification if lands are not allowed to fully recover between one grazing period and the next. Increased enclosure and fencing of land has reduced the amount of land for this practice.

In sociology, an industrial society is a society driven by the use of technology and machinery to enable mass production, supporting a large population with a high capacity for division of labour. Such a structure developed in the Western world in the period of time following the Industrial Revolution, and replaced the agrarian societies of the pre-modern, pre-industrial age. Industrial societies are generally mass societies, and may be succeeded by an information society. They are often contrasted with traditional societies.

Industrial societies use external energy sources, such as fossil fuels, to increase the rate and scale of production. The production of food is shifted to large commercial farms where the products of industry, such as combine harvesters and fossil fuel–based fertilizers, are used to decrease required human labor while increasing production. No longer needed for the production of food, excess labor is moved into these factories where mechanization is utilized to further increase efficiency. As populations grow, and mechanization is further refined, often to the level of automation, many workers shift to expanding service industries.
