Geography revision U5
Michaelmas 1:
Essential resources and inequalities:
There are inequalities in the global distribution of resources. The balance between
the supply and demand for resources affects a country's wealth and security.
UK food resources:
UK food demand
Around 40% of the UK’s food is imported.
Before supermarkets were commonplace, the majority of food was eaten seasonal
Fruit and veg were eaten depending on the season.
Now we eat all fruit and veg all year round
How has UK buying non seasonal product affected LIC’s?
Consumer demands for UK affect what is imported from other countries.
UK imports food from places such as Kenya.
The cost for UK customers are high, but there are also costs for the people in Kenya:
- Less land available
- Crops need huge amounts of water
- People growing crops are exposed to chemicals such as pesticides which can
harm them.
However, there are some advantages:
- Jobs are created
- These jobs supply wages
- From the wages, taxes are paid to the government to fund facilities.
Why have we moved to more organic products?
There has been an increasing demand for organic food including meat, fruit and
vegetables. This means that no chemicals have been added to the food.
The aim is to protect the environment and wildlife by using natural predators to
control pests
Farmers maintain the fertility of the soil by rotating crops
Weed are controlled by mechanical weeding instead of chemical weed killer
What are food miles and how to they add to the UK carbon footprint?
Food miles are the distance that food travels from the producer to consumer.
A carbon footprint is the measure of the impact that human activities have on the
environment in terms of the greenhouse gases they produce.
, Water resources UK:
Every person in the UK used about 150 litres of water
The UK has less water available that most European countries
Water stress
Water stress is when the demand for water exceeds the available amount during a
particular time period
It could cause too much water to be removed from underground sources of water
and rivers, damaging the environment
Each water company, such as Thames Water, has a 25-year plan with the E.A. This
ensures sufficient water to meet a drought with 1 month to spare.
Michaelmas 2:
Food resources:
Undernourishment:
When an individual is not getting the right amount of nutrients to be able to survive.
Most malnutrition places are in Africa, Asia and parts of South America.
Least malnutrition places are North America, Europe and Australia
Causes of food deficit:
Climate: Droughts, floods and climate change cause crops to die
Pests and disease: cattle disease, mice and rats damage harvest, malaria worsen
food insecurity as workers reduce
Technology: LIC’s lack money for agricultural infrastructure like roads, transport and
produce warehouse.
Water stress: Water stress is when the demand for water exceeds the available
amount during a particular time period
Poverty: Vicious circle of poverty: cannot afford to buy food, makes them weak/
unable to work. Poor farmers cannot afford to buy seeds which limits amount of
crops produced.
Conflict: disrupts farming; food is a weapon in war; wells deliberately polluted; aid
workers prevented from reaching people in need due to travelling through conflict
areas; International aid cannot be reached.
Impacts of food security (lack of food):
Famine and under nutrition: death; people more vulnerable to diseases
Rising prices: shortage of food can increase prices because farmers need to make
more money
