3.4 1.c, 2.a - Globalisation, land and competing theories of food security

Globalisation and changing food demand

Globalisation increases the connections through which people, businesses and places influence what food is produced and consumed.

Population growth can raise total demand, while rising income can change the type of food demanded. Some households buy more animal products, processed foods or meals prepared outside the home. Urbanisation, migration, tourism, advertising and retail networks spread products and tastes between places. These changes are conditional: income, culture, religion and personal choices mean diets do not converge everywhere into one pattern.

Changes in demand alter land and resource use. Producing animal products may require feed crops as well as grazing, water and energy. An export crop can attract investment and generate income, while competing with local food production for land or water. The effect on food security depends on whether earnings and employment improve access and whether environmental costs undermine future supply. More exports and better local nutrition are therefore separate outcomes that need to be connected through evidence.

Food firms can organise different stages across countries. A crop may be grown in one location, processed in another and sold through a retailer elsewhere. Refrigeration, container transport, information systems and common standards make long chains possible. Their benefits depend on infrastructure and the ability of suppliers to meet requirements, so better connections can include some producers while excluding others.

Food globalisation opportunities and issues

International connections can diversify food supplies and transmit technology, but can also concentrate power and spread shocks.

Imports can supply food outside a local growing season or compensate for a failed harvest. International knowledge and investment can improve breeding, storage, logistics and food safety. Short-term relief can move supplies to a crisis, while wider consumer choice can improve dietary variety. These benefits require access: an imported product on a shelf does not help a household unable to afford it.

Food miles measure the distance food travels. Distance affects transport requirements, but is not a complete measure of sustainability. Emissions also depend on vehicle type, load, refrigeration, production energy and waste. A short journey by a lightly loaded vehicle and a long sea journey cannot be compared by distance alone. Defra's food-transport work therefore uses several indicators of environmental and social effects rather than treating one distance figure as a full assessment. Defra's indicator collection.

Large buyers may bargain more strongly than small suppliers, setting prices, delivery schedules and quality requirements. Standards can improve safety and market access, but compliance costs and rejected deliveries may transfer risk to producers. Meanwhile, marketing and cheap energy-dense products can contribute to poor diets where healthier alternatives are less accessible. Obesity and food insecurity can coexist; market integration does not guarantee nutritional quality.

Nestlé and Indian dairy suppliers show how this relationship can combine resources with unequal bargaining power. Its 22 April 2024 release reported engagement with almost 80,000 Indian dairy farmers and described a programme installing biodigesters across 24 Punjab and Haryana districts. Turning manure into biogas and fertiliser can reduce purchased fuel or fertiliser costs, while the buyer connects farms to a processing market. Small suppliers nevertheless depend on payment terms, milk-quality requirements and affordable equipment. The release records the company's programme and a farmer's reported experience, rather than an independent measurement of every supplier's income or food security. Nestlé India, April 2024.

WFP's Somalia response in 2022 demonstrates a relief opportunity. Its annual report records US$470 million in cash-based transfers and 6.9 million unique beneficiaries of General Food Assistance. International finance supported household purchasing power while in-kind assistance supplied food where needed. Cash can strengthen access through functioning local markets, but its value depends on prices, supply and safe access; it cannot buy food absent from a market. The different assistance totals must not be added as though their recipient groups were separate. WFP, Somalia Annual Country Report 2022.

Swarna-Sub1 rice in eastern India illustrates cross-border research and local innovation. IRRI's January 2018 account dates dissemination from 2010 and records more than 1.7 million hectares planted in India by 2013. Breeding introduced submergence tolerance into a familiar variety, helping plants survive roughly two weeks underwater and recover after a flash flood. This can stabilise a harvest and the income purchasing other foods. Access to seed, suitable local conditions and the duration of flooding still determine effectiveness; it is a response to a particular stress rather than protection from every crop hazard. IRRI, January 2018.

Global networks also transmit price shocks. Conflict, harvest failures, energy costs and export restrictions can interact to raise world prices. FAO's January 2023 account records the unusually high annual Food Price Index in 2022, following major increases in 2021. That international commodity index is not a direct measurement of every household's retail bill: exchange rates, subsidies, distribution and incomes shape local effects. FAO, 6 January 2023.

Physical controls, ownership and land grabbing

Food security reflects both the productive potential of land and the rules determining who can use it and benefit from it.
