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 
  • 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)

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 
  • 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.
