What three things are fundamental to human development
Food water and energy
Define human development
The progress of a country and its people in terms of economic growth, use of technology and human welfare
Define economic wellbeing
A measure of how much money people have to sustain their standard of living
Define social wellbeing
The social condition of an individual or group
Which is harder to measure
Social wellbeing
Name five things to measure social wellbeing
Family friends sleep school and food
What is energy crucial for
Water treatment, food picking and technology
What can food also be used as
Money as it can be traded
Access to electricity is sparser in what hemisphere
Southern, and centre of the continents have less than the coasts
Define global inequality
The difference between countries consumption and supply
Define resource supply
The amount of a certain resource available in that country
Define resource consumption
The amount of that certain resource that is used up by that country
In the olden days in the uk, food…
Was locally/home grown and produced seasonally
Now food in the uk is…
Non seasonal, as produce out of season is shipped in from places where the climate is better and the prices are cheaper
Name two pros of importing food form Kenya
Adds to Kenya’s economy
Provides jobs for Kenyans
Are two cons of importing food from Kenya
Large rejection of produce and it is unsustainable
What is leeching
When fertilisers get into the water sources
In non organic farming…
Pesticide is added to the crops, and these chemicals add miles. Due to expectations there are less farmers
How much less energy is used during organic farming
30% less
What can organic farming increase
Nutrient and vitamin intake
When did sales of organic produce spike and dip
Spiked in 2008 and dipped in 2011
What is water supply
The provision of water by individuals, communities, public bodies and companies
What is water demand
The quantity of water that’s required to meet peoples needs
What are water transfer schemes
The movement of water via pipe of truck from areas of supply to areas of demand
What is the largest uk reservoir
Kielder
Name another uk reservoir
Gaig goch
What is an aquifer
A geological structure where the rick has to contain calcium
Why is there a rising demand for water
Rising population, global warming, increased wastage and old pipes leak which wastes 30% of all water
Where is the highest rainfall in uk
North west Scotland
Where is the population densest in the uk
Central and southern uk
Name 5 downfalls in long range water transfers
Abusing the source, affecting ecology, expensive, destructive pipelines and a large amount of carbon emissions
Name some positives of long range water transfer
Creates hydro electric power
How can water be contaminated
Fertilisers, animal waste, warm water
How to maintain water cleanliness
Legalisation (government standards), pollution traps, system of water treatment and green walls and roofs.
What country is the largest use of energy
China but per person, its America
Where do we get coal from
Wales
Where do we get gas from
North Sea
Which non renewable is first to deplete
Oil in 2050
What is fracking
Obtaining shale gas by pumping a mix of sand and water into shale rock and shattering pockets
What percentage of the planets water is freshwater
2.5%
What is water surplus
Enough water to meet demand
What is water deficit
Not enough water to meet demand
What is physical water scarcity
Where a country can’t access water due to climate or landscape
What is economic water scarcity
Where a country has water but not the money to access it or make it safe to drink
What is water security
The reliable availability of a quantity and quality of water for health, livelihoods and production
What is water insecurity
When water availability is not enough to ensure the population of an area enjoys good health, livelihood and earnings.
What can water insecurity be caused by
Water insufficiency or poor water quality
What is water stress
Occurs when the demand for water exceeds the available amount during a certain period
How do we make more water available
Finding new sources or moving it from areas of surplus to areas of deficit
What are the positives and negatives of desalination
P- limited energy, huge body of water, isn’t affected by drought
N- ugly, concentrated water, harm biodiversity, upkeep expensive
What are the positives as negatives of dams
P- hydro electricity, sustainable
N- flooding at reservoir, ruining habitats, downstream fishing stops
What 2 criteria have to be met to be sustainable
Achieve a balance between supply and demand
Ensure that this balance is maintained regardless of population increase
What is the uks main source of water
Groundwater
What are problems with groundwater
Pollution by industry, overuse and no one controls it
Name some sustainable solutions to groundwater
Grey water - recycling
Stop leakages
Irrigation such as drip pipes
Controlling pollution
