The British Agricultural Revolution, or Second Agricultural Revolution, was an unprecedented increase in agricultural production in Britain arising from increases in labour and land productivity between the mid-17th and late 19th centuries. Agricultural output grew faster than the population over the hundred-year period ending in 1770, and thereafter productivity remained among the highest in the world. This increase in the food supply contributed to the rapid growth of population in England and Wales, from 5.5 million in 1700 to over 9 million by 1801, though domestic production gave way increasingly to food imports in the nineteenth century as the population more than tripled to over 35 million. Using 1700 as a base year (=100), agricultural output per agricultural worker in Britain steadily increased from about 50 in 1500, to around 65 in 1550, to 90 in 1600, to over 100 by 1650, to over 150 by 1750, rapidly increasing to over 250 by 1850. The rise in productivity accelerated the decline of the agricultural share of the labour force, adding to the urban workforce on which industrialization depended: the Agricultural Revolution has therefore been cited as a cause of the Industrial Revolution.
Agricultural productivity is measured as the ratio of agricultural outputs to inputs. While individual products are usually measured by weight, which is known as crop yield, varying products make measuring overall agricultural output difficult. Therefore, agricultural productivity is usually measured as the market value of the final output. This productivity can be compared to many different types of inputs such as labour or land. Such comparisons are called partial measures of productivity.
Food security is the measure of the availability of food and individuals' ability to access it. According to the United Nations' Committee on World Food Security, food security is defined as meaning that all people, at all times, have physical, social, and economic access to sufficient, safe, and nutritious food that meets their food preferences and dietary needs for an active and healthy life. The availability of food irrespective of class, gender or region is another one. There is evidence of food security being a concern many thousands of years ago, with central authorities in ancient China and ancient Egypt being known to release food from storage in times of famine. At the 1974 World Food Conference, the term "food security" was defined with an emphasis on supply; food security is defined as the "availability at all times of adequate, nourishing, diverse, balanced and moderate world food supplies of basic foodstuffs to sustain a steady expansion of food consumption and to offset fluctuations in production and prices". Later definitions added demand and access issues to the definition. The first World Food Summit, held in 1996, stated that food security "exists when all people, at all times, have physical and economic access to sufficient, safe and nutritious food to meet their dietary needs and food preferences for an active and healthy life."
Agriculture is a major industry in the United States, which is a net exporter of food. As of the 2017 census of agriculture, there were 2.04 million farms, covering an area of 900 million acres (1,400,000 sq mi), an average of 441 acres per farm.
Robert William Fogel was an American economic historian and scientist, and winner of the 1993 Nobel Memorial Prize in Economic Sciences. As of his death, he was the Charles R. Walgreen Distinguished Service Professor of American Institutions and director of the Center for Population Economics (CPE) at the University of Chicago's Booth School of Business. He is best known as an advocate of new economic history (cliometrics) – the use of quantitative methods in history.
Malthusianism is the idea that population growth is potentially exponential while the growth of the food supply or other resources is linear, which eventually reduces living standards to the point of triggering a population die off. This event, called a Malthusian catastrophe occurs when population growth outpaces agricultural production, causing famine or war, resulting in poverty and depopulation. Such a catastrophe inevitably has the effect of forcing the population to "correct" back to a lower, more easily sustainable level. Malthusianism has been linked to a variety of political and social movements, but almost always refers to advocates of population control.
The history of agriculture in the United States covers the period from the first English settlers to the present day. In Colonial America, agriculture was the primary livelihood for 90% of the population, and most towns were shipping points for the export of agricultural products. Most farms were geared toward subsistence production for family use. The rapid growth of population and the expansion of the frontier opened up large numbers of new farms, and clearing the land was a major preoccupation of farmers. After 1800, cotton became the chief crop in southern plantations, and the chief American export. After 1840, industrialization and urbanization opened up lucrative domestic markets. The number of farms grew from 1.4 million in 1850, to 4.0 million in 1880, and 6.4 million in 1910; then started to fall, dropping to 5.6 million in 1950 and 2.2 million in 2008.
In the history of the Southern United States, the Antebellum Period spanned the end of the War of 1812 to the start of the American Civil War in 1861. The Antebellum South was characterized by the use of slavery and the culture it fostered. As the era proceeded, Southern intellectuals and leaders gradually shifted from defending slavery as an embarrassing and temporary system, to a full-on defense of slavery as a positive good, and harshly criticized the budding abolitionist movement.
The domestic slave trade, also known as the Second Middle Passage and the interregional slave trade, was the term for the domestic trade of enslaved people within the United States that reallocated slaves across states during the Antebellum period. It was most significant after 1808, when the importation of slaves was prohibited. Historians estimate that one million slaves were taken in a forced migration from the Upper South, primarily Maryland and Virginia, to the territories and then new states of the Deep South: Georgia, Alabama, Florida, Louisiana, Mississippi, Arkansas, and Texas.
The history of agriculture in India dates back to the Indus Valley civilization. India ranks second worldwide in farm outputs. As per 2018, agriculture employed more than 50% of the Indian work force and contributed 17–18% to country's GDP.
Nicaragua produces coffee, cotton, bananas, sugar and beef cattle.
The main economic products of Malawi are tobacco, tea, cotton, groundnuts, sugar and coffee. These have been among the main cash crops for the last century, but tobacco has become increasingly predominant in the last quarter-century, with a production in 2011 of 175,000 tonnes. Over the last century, tea and groundnuts have increased in relative importance while cotton has decreased. The main food crops are maize, cassava, sweet potatoes, sorghum, bananas, rice, and Irish potatoes and cattle, sheep and goats are raised. The main industries deal with agricultural processing of tobacco, tea and sugar and timber products. The industrial production growth rate is estimated at 10% (2009).
Agriculture in Ghana consists of a variety of agricultural products and is an established economic sector, providing employment on a formal and informal basis. It is represented by the Ministry of Food and Agriculture. Ghana produces a variety of crops in various climatic zones which range from dry savanna to wet forest which run in east–west bands across Ghana. Agricultural crops, including yams, grains, cocoa, oil palms, kola nuts, and timber, form the base of agriculture in Ghana's economy. In 2013 agriculture employed 53.6% of the total labor force in Ghana.
Angola is a potentially rich agricultural country, with fertile soils, a favourable climate, and about 57.4 million ha of agricultural land, including more than 5.0 million ha of arable land. Before independence from Portugal in 1975, Angola had a flourishing tradition of family-based farming and was self-sufficient in all major food crops except wheat. The country exported coffee and maize, as well as crops such as sisal, bananas, tobacco and cassava. By the 1990s Angola produced less than 1% the volume of coffee it had produced in the early 1970s, while production of cotton, tobacco and sugar cane had ceased almost entirely. Poor global market prices and lack of investment have severely limited the sector since independence.
Nutritional anthropology is the study of the interplay between human biology, economic systems, nutritional status and food security. If economic and environmental changes in a community affect access to food, food security, and dietary health, then this interplay between culture and biology is in turn connected to broader historical and economic trends associated with globalization. Nutritional status affects overall health status, work performance potential, and the overall potential for economic development for any given group of people.
The economy of South Carolina was ranked the 25th largest in the United States based on gross domestic product in 2020. Tourism, centered around Myrtle Beach, Charleston, and Hilton Head Island, is the state's largest industry. The state's other major economic sector is advanced manufacturing located primarily in the Upstate and the Lowcountry.
Thomas McKeown (1912–1988) was a British physician, epidemiologist and historian of medicine. Largely based on demographic data from England and Wales, McKeown argued that the population growth since the late eighteenth century was due to improving economic conditions, i.e. better nutrition, rather than to better hygiene, public health measures and improved medicine. This became known as the "McKeown thesis".
Anthropometric history is the study of the history of human height and weight. It has historical roots. In the 1830s, Adolphe Quetelet and Louis R. Villermé studied the physical stature of populations. In the 1960s, French historians analyzed the relationship between socio-economic variables and human height. Anthropometric history was established as field of study in the late 1970s when economic historians Robert Fogel, John Komlos, Richard Steckel and other academics began to study the history of human physical stature and its relationship to economic development. A branch of cliometrics, it uses trends and cross-sectional patterns in human physical stature to understand historical processes.
The process of de-industrialisation is an economic change in which employment in the manufacturing sector declines due to various economic or political reasons. The decline in employment in manufacturing is also followed by the fall in the share of manufacturing value added in GDP. The process of de-industrialisation can be due to development and growth in the economy and it can also occur due to political factors. In other words, the term de-industrialisation means a general reduction in the industrial capacity and came into prevalence in India with the decline and collapse of the handicrafts industry by external competition from British-manufactured products during the 19th century.
Sustainable Development Goal 2 aims to achieve "zero hunger". It is one of the 17 Sustainable Development Goals established by the United Nations in 2015. The official wording is: "End hunger, achieve food security and improved nutrition and promote sustainable agriculture". SDG 2 highlights the complex inter-linkages between food security, nutrition, rural transformation and sustainable agriculture. According to the United Nations, there are around 690 million people who are hungry, which accounts for slightly less than 10 percent of the world population. One in every nine people goes to bed hungry each night, including 20 million people currently at risk of famine in South Sudan, Somalia, Yemen and Nigeria.
