food production and consumption

how much has food production growth by in the last 50 years

it has tripled

how much has global arable land increased by in the past 50 years

67 million hectares (although it has decreased in developed countries)

give some reasons why food production has increased globally

• an increased use in farming machinery (e.g. combine harvesters) which allows for more crops to be collected in a quicker time frame

• increased use of other farming resources, such as herbicides and pesticides, to maximise yields

• better farming management to maximise yields and create more farmable land

where has food production increased in different regions and for what reasons

• wheat and rice production has increased in Asia and Northern Africa due to higher yields

• maize production has increased in Latin America and the Caribbean due to methods of land expansion (creating more arable land)

how is food production unevenly distributed

• lower income countries produce the least amount of crops

• the richest countries have the largest food supplies

give an example of regions with differing crop yields

• Eastern Asia, North America and Western Europe are areas with consistently high yields due to their availability of resources such as nutrients and water. Eastern Asia receives high amounts of rainfall, facilitating crop growth.

• Central Australia, saharan Africa and eastern Russia have low crop yields due to extreme environmental limitations, such as droughts and temperatures unsuitable for crop growth.

globally, how has food consumption changed

it has increased over time- there are more people consuming food, and per person they are consuming more food

why do HICs consume more food than LICs

they have more money to import food and invest in agriculture, swell as more money per person to buy food.

what continent consumes the least calories

Africa

what continent consumes the most calories

North America, followed by Europe

what continent has seen the quickest growth in consumption

asia (Chinas consumption has increased by nearly 1000 calories in 50 years)

how does the consumption of cereals vary across the globe

• in Africa, cereals account for up to 70% of energy intake, whereas in high income countries it is around 30%

what type of countries consume the most meat

developed countries eat the most meat, whereas developing countries tend to get their protein from non-animal based sources

how does the consumption of eggs and dairy vary

• developed countries dominate the consumption of animal products, although egg consumption has increased in some developing countries

• Africa has the lowest consumption of dairy

how does the consumption of fats oils and sugars vary

consumption is highest in HICs due to consumerist culture
