Resource Management Flashcards
Learn about water management as a resource.
Why does the UK import so much food?
We don’t have a climate for certain foods all year. We have a very diverse diet so we want more different foods. However this causes UK farmers to go out of business.
What does organic mean?
Food production without additional chemicals. It’s better for the environment. However this is more expensive and leads to less food.

What affects water quality?
Runoff
Factories
Landfill

What are the effects of fossil fuels?

What are the 4 impacts of water Insecurity?

Ways to ensure water supply
Water supply- water is redirected but it’s very costly, for example the $79 billion Chinese NS pump.
Desalination- uses a plentiful source. There are environment impacts on ecosystems.
Dams+Reservoirs- Controls water supply but it’s expensive but create stress.
Increasing storage- collects water and doesn’t require transportation. Requires drilling.
Facts about the Chinese north-south transfer system:
300,000 people displaced.
Costs $79 billion
Provides reliable water for 200 million people
