Variations in Food Consumption
- Food production and food consumption are increasing globally
- Global food production is efficient
- There is currently enough food to feed all the people on the planet
- Food production has increased due to:
- Land availability e.g. from deforestation, wetland clearing and brownfield site conversion
- Increased productivity, due to:
- Mechanisation of farming
- Genetically modified high-yielding crops
- Agrochemicals
- Irrigation systems
- Increased wealth - increases the demand for higher-cost foods like seasonal foods or meat
- Education - more knowledge about food choices
- Globalisation - food is globally distributed via plane, ship, road and rail through international trade routes
- However, food consumption is unequal
- Increased food production does not mean there is increased consumption everywhere
- Food consumption varies regionally and internationally
- HICs consume more calories than LICs
- Some areas are food secure whilst others are food insecure
- In some cases, food security can result in food surplus and food waste
- Food insecurity results in food deficits
- Human and physical factors affect food consumption around the world

Human factors
Development
- Development is rising across the world
- As countries become more developed and the middle class grows, food consumption increases
- People can afford more food or more expensive/calorie-rich foods like meat
- China’s meat consumption increased
- In 1980 it was 12kg per person, by 2023 it was over 62kg per person
- This increase has occurred as the country has developed and incomes have risen
- With globalisation, people demand more non-seasonal or non-local foods
- As more people learn about food miles and environmental change, consumption of seasonal foods may change
- People can afford more food or more expensive/calorie-rich foods like meat
- Population growth is booming in LICs, which creates pressure on food demand
- Food shortages may occur if population growth outweighs agricultural productivity
- People in poverty-stricken areas in LICs may find themselves unable to afford food
- This can mean they cannot go to work to earn money due to hunger or ill health
- This becomes a vicious cycle
- Lack of infrastructure in LICs can reduce the amount of food transported to an area
- Farmers in LICs may not be able to afford fertilisers or other agricultural technologies to increase their crop yields
Politics
- Food consumption may increase with food aid from international governments or charities
- In some areas, conflict can hinder food consumption
- People may flee a war-torn area, leading to a lack of food access
- Warfare can damage crops and kill livestock
- Food may be weaponised, and food supplies taken away
- Food prices globally may rise, meaning food becomes unaffordable (not just in LICs, but in HICs too)
- Political corruption or instability in countries limits food aid from reaching those who need it most e.g. in the Democratic Republic of the Congo
- These issues may impact people’s accessibility to food
- This results in a Food Entitlement Deficit (FED)
- These issues may impact people’s accessibility to food
Trade
- Although globalisation has increased food movement, trade inequalities still exist
- LICs export more food than they keep, leaving behind food insecurities
- LICs rely on export earnings
- These countries have less money to import food
- This results in an imbalance in food production, exports and imports in LICs
- HICs can afford to import more foods, resulting in a large discrepancy between LICs and HICs
- The global Fair Trade movement protects farmers in LICs by providing them with a reliable income to afford food
Type of food
- Diet can impact the levels of calorie consumption
- More developed countries have a higher calorie consumption, as diets are richer in fats and sugars
- Less developed countries consume less calories, as diets focus on lower fat and higher fibre diets
- The stages of the Nutrition Transition directly affect food consumption and the related effects
Physical factors
Climate, water and soil
- Climate impacts the ability to grow crops, resulting in food shortages
- Droughts can cause infertile soils and desertification
- Flooding can damage crops and livestock
- Water stress or water insecurity can cause crop yields to be very low
- This is caused by:
- Low rainfall
- Pollution caused by flooding
- High population density
- Poorer countries may not be able to afford technologies like irrigation systems, to reduce drought-associated problems
- This is caused by:
- Poor soil quality increases erosion and reduces crop yields
- Some soils are nutrient-rich and can hold water, ideal for crop growth
- Farmers in poverty may not be able to afford fertilisers or other tools which increase crop yields
Climate change
- Climate change is rapidly exacerbating food insecurity and food shortages
- Climate change increases flooding, droughts and storms which reduces crop yields, kills livestock and affects the global food trade
- This results in a Food Availability Deficit (FAD)
- Increased carbon dioxide in the atmosphere can reduce the nutritional density of crops
- Climate change also impacts our oceans and the world’s fisheries, with rising ocean temperatures and ocean acidification
- Rising sea levels pose a threat to coastal agricultural land
Pests and disease
- Pests and diseases can damage crops, reducing crop yields
- This is exacerbated in warmer countries, or where there is not enough money for pesticides
- Climate change also increases pests and diseases
Examiner Tip
Remember to think about why food production may be higher or lower. The amount of food production has a direct effect on food consumption around the world.
