Resource Management Flashcards
What is a resource
A stock/supply of something that has a value or purpose
What is QoL
An individual’s perception of their life at that current moment
What is standard of living

How is demand for food changing in the UK
Growing demand in:
Exotic fruits
Out of season produce
Organic alternatives
In 2019 what percentage of food eaten in the UK came from Latin America
12%
An example of a UK farm that supplies organic food
Riverford Organic Farms, Devon
They started to:
Reduce food miles
Support local farmers
Provide local employment
Build a strong link between grower and consumer
How does food demand affect the UK’s carbon footprint
It increases as there are more food miles attributed to the UK
What has happened in the UK due to growing concerns about greenhouse gas emissions (food)
A move towards local sourcing food
Why is demand for water changing in the UK
Demand for water is increasing due to:
Population increase
Greater use of domestic appliances
Increased demand for irrigation
Increased use for leisure
Rapid growth of house building
How much water did the average person in 2019 consume each day
143 L
When could demand for water exceed supply in the UK
2034
Which areas of the UK have water surpluses
North and West
Which areas of the UK have a water deficit
South and East
What is water stress
Demand exceeds supply
What do water transfer schemes do
Attempt to match supply and demand by moving water from areas with surplus to areas with deficit
Example of a water transfer scheme
Kielder reservoir, UK
Advantages of the Kielder water transfer scheme
Regulates flow of the Tyne
Produces power
Stores water to reduce flood risk downstream
Employment opportunities
100,000 ha nature reserve
Disadvantages of the Kielder water scheme
Flooded an AONB
Displaced farming communities
1.5 million trees cut down
Expensive
When was the Kielder water reservoir built
Began 1975
Finished 1982
How many rivers in 2020 were pollution free
0
What is the water treatment process
Collecting rain
Storing water
Screening water
Removing any particles
Removing bacteria
Transported
How does the environment agency manage water pollution
Filtering water
Monitoring quality of water
Legislation on what can be discharged into rivers
Regulation on uses of water
Sources of water pollution
Factories
Oil spills
Sewage
Surface run off
How has the UK’s energy mix changed since 1990
More renewables
Less coal
More gas
Less oil
Less nuclear
Where is the world’s largest offshore wind farm
Hornsea 1
North Sea off the Yorkshire coast
Why is food consumption increasing
Economic development
Population growth
Greater availability of food
Dietary changes
What is food security
Having access to enough safe, affordable and nutritious food to maintain a healthy and active life
Factors affecting food supply
Climate
Pests and disease
Water stress
Conflict
Poverty
Technology
What is food insecurity
When a country can’t supply enough food at an appropriate price to feed it’s population
How can food supply be increased
Irrigation
Aeroponics and hydroponics
Modern farming techniques
Biotechnology
What is aeroponics
Plants are sprayed with fine water mist containing nutrients
What is hydroponics
Plants are grown in gravel or mineral-rich water
What is sustainable food supply
Ensures that fertile soil, water and environmental resources are available for future generations
Types of sustainable food supply
Organic farming
Permaculture
Urban farming
Fish and meat from sustainable sources
What is water stress
More than 80% of the available water is being used
China South-North water transfer
$62 billion project
Transfer 44.8 billion m^3 of water each year
100 million people have benefitted from the project
Should stop over-extraction
However raising dams can lead to flooding and the water is quite expensive
How to make water supply more sustainable
Using grey water
(In Jordan 70% of water used for irrigation is grey water as it can be used within 24 hrs for fertiliser)
Groundwater management
Recycling (eg powerplants in Arizona use recycled water for cooling)
Lesotho Highland Water project
40% of the water from the River Segu will be diverted to Jo.burg via the river Vall
Will take 30 years to complete
It will boost Lesotho’s economy by 75%
30,000 local residents have been re-located
Costs for SA are likely to reach $4 billion
40% of water is lost through leakages
Provides 10% more water to the population
