Food prices in the context of "2010–2012 Algerian protests"

The Corn Laws were tariffs and other trade restrictions on imported food and corn enforced in the United Kingdom between 1815 and 1846. The word corn in British English denotes all cereal grains, including wheat, oats and barley. The laws were designed to keep corn prices high to favour domestic farmers, and represented British mercantilism. The Corn Laws blocked the import of cheap corn, initially by simply forbidding importation below a set price, and later by imposing steep import duties, making it too expensive to import it from abroad, even when food supplies were short. The House of Commons passed the corn law bill on 10 March 1815, the House of Lords on 20 March and the bill received royal assent on 23 March 1815.

The Corn Laws enhanced the profits and political power associated with land ownership. The laws raised food prices and the costs of living for the British public, and hampered the growth of other British economic sectors, such as manufacturing, by reducing the disposable income of the British public.

The FAO Food Price Index (FFPI) is a food price index by the Food and Agriculture Organization (FAO) of the United Nations. It records the development of world market prices of 24 agricultural commodities and foodstuffs from five major food commodity groups. The FFPI is considered an indicator of future inflation and cost trends in the food industry.

There are numerous effects of climate change on agriculture, many of which are making it harder for agricultural activities to provide global food security. Recent research has found that climate change is likely to exacerbate the existing environmental impacts of agriculture by lowering crop productivity, reducing the effectiveness of agrochemicals, increasing soil erosion and pest pressures, and thereby driving greater use of land, water and inputs.Rising temperatures and changing weather patterns often result in lower crop yields due to water scarcity caused by drought, heat waves and flooding. These effects of climate change can also increase the risk of several regions suffering simultaneous crop failures. Currently this risk is rare but if these simultaneous crop failures occur, they could have significant consequences for the global food supply. With a growing population and rapid urbanization, it is suggested that food production may increase by nearly 60% in the upcoming years. Verma, Krishnan (13 August 2024). "Climate change adaptation: Challenges for agricultural sustainability". Wiley. Wiley. Retrieved 30 October 2025.. Many pests and plant diseases are expected to become more prevalent or to spread to new regions. The world's livestock are expected to be affected by many of the same issues. These issues range from greater heat stress to animal feed shortfalls and the spread of parasites and vector-borne diseases.

The increased atmospheric CO₂ level from human activities (mainly burning of fossil fuels) causes a CO₂ fertilization effect. This effect offsets a small portion of the detrimental effects of climate change on agriculture. However, it comes at the expense of lower levels of essential micronutrients in the crops. Furthermore, CO₂ fertilization has little effect on C4 crops like maize. On the coasts, some agricultural land is expected to be lost to sea level rise, while melting glaciers could result in less irrigation water being available. On the other hand, more arable land may become available as frozen land thaws. Other effects include erosion and changes in soil fertility and the length of growing seasons. Bacteria like Salmonella and fungi that produce mycotoxins grow faster as the climate warms. Their growth has negative effects on food safety, food loss and prices.

During 2022 and 2023 there were food crises in several regions as indicated by rising food prices. In 2022, the world experienced significant food price inflation along with major food shortages in several regions. Sub-Saharan Africa, Iran, Sri Lanka, Sudan and Iraq were most affected. Prices of wheat, maize, oil seeds, bread, pasta, flour, cooking oil, sugar, egg, chickpea and meat increased. Many factors have contributed to the ongoing world food crisis. These include supply chain disruptions due to the COVID-19 pandemic, the Global energy crisis (2021–2023), the Russian invasion of Ukraine, and floods and heatwaves during 2021 (which destroyed key American and European crops). Droughts were also a factor; in early 2022, some areas of Spain and Portugal lost 60–80% of their crops due to widespread drought.

Even before the Russian invasion of Ukraine, food prices were already at a record high. 82 million East Africans and 42 million West Africans faced acute food insecurity in 2021. By the end of 2022, more than 8 million Somalis were in need of food assistance. In February 2022, the Food and Agriculture Organization (FAO) reported a 20% rise in food prices since February 2021. The war further pushed this increase to 40% in March 2022 but was reduced to 18% by January 2023. But the FAO warns that inflation of food prices will continue in many countries.

John Bright (16 November 1811 – 27 March 1889) was a British Radical and Liberal statesman, one of the greatest orators of his generation and a promoter of free trade policies.

A Quaker, Bright is most famous for battling the Corn Laws. In partnership with Richard Cobden, he founded the Anti–Corn Law League, aimed at abolishing the Corn Laws, which raised food prices and protected landowners' interests by levying taxes on imported wheat. The Corn Laws were repealed in 1846. Bright also worked with Cobden in another free trade initiative, the Cobden–Chevalier Treaty of 1860, promoting closer interdependence between Great Britain and the Second French Empire. This campaign was conducted in collaboration with French economist Michel Chevalier, and succeeded despite Parliament's endemic mistrust of the French.

The National School Lunch Act (79 P.L. 396, 60 Stat. 230) is a 1946 United States federal law that created the National School Lunch Program (NSLP) to provide low-cost or free school lunch meals to qualified students through subsidies to schools. Prior to the passage of the Act, direct support of school lunches were done on the state level, or it was provided through federal aid that was not specifically designed for school lunches.

The program was established as a way to prop up food prices by absorbing farm surpluses, while at the same time providing food to school-age children. The Act was signed into law by President Harry S. Truman in 1946 and entered the federal government into schools' dietary programs on June 4, 1946. In 1999, the act's name was changed to honor Richard Russell Jr., senator from Georgia, who championed its passage.

Manchester Liberalism (also called the Manchester School, Manchester Capitalism and Manchesterism) comprises the political, economic and social movements of the 19th century that originated in Manchester. Led by Richard Cobden and John Bright, it won a wide hearing for its argument that free trade would lead to a more equitable society, making essential products available to all. Its most famous activity was the Anti-Corn Law League that called for repeal of the Corn Laws that kept food prices high. It expounded the social and economic implications of free trade and laissez-faire capitalism. The Manchester School took the theories of economic liberalism advocated by classical economists such as Adam Smith and made them the basis for government policy. It also promoted pacifism, anti-slavery, freedom of the press and separation of church and state.
