Resource Managment (Unit 2C) Flashcards
Lack of resources (Food)
- A lack of food can lead to malnourishment or undernourishment
- This can limit children’s development and increase the likelihood of getting ill
- Crops are sold for profit/wealth
Lack of resources (Water)
- Water born diseases are more prevalent
- Water sources become polluted with sewage (without any sanitation)
- Products cannot be manufactured, and crops cannot be grown
Lack of resources (Energy)
- Countries cannot develop industry, create jobs and therefore develop less wealth
- Homes cannot be heated, work and education cannot continue when it’s dark
Global consumption of resources
- HICs consume more resources as they can afford to import more
- NEEs consumption of resources is rapidly increasing due to more wealth and population
- LICs consume little resources as they either can’t afford to import it or can’t exploit resources
Carbon footprint
The amount of greenhouse gases produced by a particular product or individuals activities
Food miles
The distance covered supplying food to consumers
Effects of food miles
Having high food miles means that food is imported from further away, and therefore has a larger environmental impact (carbon footprint) then food that’s imported from closer to home
Seasonal products
Foods that are only available at certain times of year when grown (e.g. strawberries in summer)
👇
These foods are then imported to meet demands all year round (e.g. strawberries in Mexico)
High value foods
As people get more wealth (in HICs) the demand for exotic foods has become more popular and these foods are often grown and imported from LICs
Organic produce
As peoples concerns for chemicals in food production grows, as well as the environmental impacts, the demand for organic food is increasing as it has strict regulations
Organic farming
small scale farming which doesn’t use any chemicals (e.g. fertilisers)
👇
This food is often grown locally and therefore has less food miles (a smaller carbon footprint)
Local food production
Producing food more locally reduces the amount of food miles as food is transported across a smaller distance to reach the consumer
Agribusiness
Intensive UK farming that uses chemicals (e.g. pesticides) to produce large quantities of food quickly
👇
This is likely to increase in the UK as population grows
Why is water demand increasing?
- Increased population
- Increased use of appliances (e.g. dishwashers)
- Industrial production
- Increased frequency of people washing
Distribution of water
The more densely populated areas are near the South-East of the country, but most rainfall occurs in the North-West
👇
This shows that more densely populated areas (aka the areas of fewer rainfall) are the areas of more water stress, as not enough rain falls to meet water demand
Water transfer schemes
When water is moved from ares of surplus to areas of water of deficit (using a pipes network) to reduce water stress
Issues of water transfer schemes
- Dams and pipe networks are expensive to build
- Greenhouse gases released (when pumping water over large distances)
- Effect wildlife living in rivers (dams and reservoirs)
Causes of water pollution
- Chemical and oil spills from factories
- Pollution from boats and ships (oil/diesel)
- Sewage pumped into rivers
- Run off from roads (oils and fuel from roads run into rivers)
- Flushing wrong things down the toilet or in rivers (diesel or baby wipes)
Water pollution management
- Better water treatment plants
- Education campaigns (don’t flush the wrong things into toilets)
- Regulating the amount of fertilisers and chemicals used
The UKs energy mix
- Shows that overtime the UK has become less reliant on coal and oil, but rely almost entirely on natural gas right now
- In recent years, renewable energy sources have increased due to the need to reduce greenhouse gas emissions (mainly biogas and wind power)
Supplies of non-renewable energy
Gas, oil and coal reserves are running out within (and outside of) the UK, coal reserves have significantly decreased since the mid 20th century
Issues of exploiting energy sources (economic)
- Cost of extraction is expensive
- Money is required to research into alternative energy sources
- Production doesn’t meet the UK so it has to be imported
- Expensive for the consumer (renewable)
Issues of exploiting energy sources (environmental)
- Fossil fuels release greenhouse gases
- Fracking pollutes groundwater and causes mini Earthquakes
- Oil spills damage water sources and soil
- Natural ecosystems damaged by renewable energy generators
- Power stations and wind rams are known as eyesores
