Resource Security Flashcards
What is a resource?
Something that has value and is made use of by people
What are the two types of resource (not stock or flow)?
Human and physical resources
What is resource security?
The abilllity to safeguard a reliable and sustainable flow of resources to maintain the living standards of a population - is dealt with on a national level.
What are the three types of resources?
Stock
Flow
Critical flow
What is a stock resource?
A resource which is finite and non renewable, including things such as metal ores and mineral deposits
What is a flow resource?
Renewable resources that are infinite, e.g. solar energy and wind power
What is a critical flow resource?
Flow resources that can be exhausted if not managed effectively
What is a possible resource?
When there are in situ indicators that a resource reserve may be present in an area, but no sampling has been carried out. At this stage there is insignificant data to justify an exploration phase and the degree of mineral sampling confidence is insignificant.
What is an inferred resource?
When it is estimated that there is a resource in the area on the basis of limited sampling into the geology. Limited information is gathered and little sampling is done
There is insufficient data to justify the expenditure on planning the exploration phase
What is an indicated reserve?
There is greater confidence of a resource being present in an area. Mine / quarry / boring is considered, and the size of the revenue has been partially measured to create an estimate for its complete size. There is evaluation of the economic viability of deposits.
At this stage the geological and grade consistency tests to be reasonably assumed
Chance of 50% or greater that mineralisation occurs
What is a measured reserve?
The reserve has been fully measured and is known accurately, plans for mining have been detailed, and resource extraction will go ahead - assuming it is economically viable
Sufficient sample tests allow geological and grade consistency to be confirmed
Chance of 90% or greater that mineralization occurs
What are the 4 types of resources in order of confidence (low to high)?
Possible resource
Indicated resource
Inferred reserve
Measured reserve
What are potential stocks?
Stocks/reserves that have been evidenced but not fully quantified or explored
What are known stocks?
Stocks that are quantified and accesible
What are estimated stocks?
When quantification is difficult and the size of the reserve must be estimated
What are depleting reserves?
When the rate of exploitation is quicker than the speed of recovery
What are exhausted stocks?
When economically recoverable (viable) stocks have been fully depleted
What are the factors that decide whether a reserve is economically viable?
- Market price
- Size of stock
- Grade
- Remoteness/accessibility
- Political situation
What are the 8 stages of the mineral resources devlopment cycle and how long is each stage?
- Available land resources
- Exploration (8-10 years)
Environmental assesment and approval + ongoing stakeholder consultations - Construction (1-3 years)
- Operation (10-30 years)
- Closure (1-2 years)
- Monitoring (5-infinity years)
- Reclamation (1-4 years)
What is an environmental impact assesment (EIA)?
An EIA is a process where the impacts on the environment of a proposed project are gauged. Here, any unacceptable measures can be mitigated and reduced by taking relevant measures
What is an EIS?
An environmental impact survey comes following an EIA states what has been found and what needs to be done - it ensures decision makers consider the environment during projects and whether to go ahead with the project or not
What has increasingly complex and vague international environmental laws meant?
Construction projects are taking much longer and more expensive, with specialist contractors like the TNC Schlumburger that can be hired to prepare EIS’s and ensure their approval by the relevant authorities
What is the resource peak?
The global maximum production of a resource
What is hubberts peak?
A graph that implies that maximum oil production or global oil reseres will occur toward the middle of the reserves life cycle
When does the resource peak occur?
About 40 years after the discovery peak
What can hubberts curve be used for?
Used during exploration and prodcution companies to estimate future production rates
It also indicates when oil will be cheapest and consumers will be buying/consuming more of the resource.
What can cause a quick decline in production after peak oil?
Because the highest quality and most accesible oil will be extracted first, the decline of production of peak oil may be hastened by more challenging extraction and production processes.
What is a resource frontier?
A place where it is possible to get a resource from which it wwas previously had not been exploited from before.
Why may a resource frontier not been exploited from before?
-It was not technically possible to exploit
-It had previously been too expensive to exploit or just not economically viable
What is the best example of a resource frontier?
The Arctic
Why has it been difficult to exploit resources from the Arctic?
Remoteness -> Difficult to get people there especially in winter months
Weather/climate -> Difficult to operate there
Communications
Environmental sensitivity
Icebergs
Why is the Arctic now a resource frontier?
Climate change is making the Arctic more exploitable
- Shell has been given licenses from the US gov to exploit the arctic, although haven’t done so as oil prices have been unstable and the need to avoid a PR distaster
- Russia has begun drilling for oil creating many oil spills already
What are examples of resource frontiers other than the Arctic?
- Athabasca Tar sands
- Deep water drilling in the gulf of mexico (deep water horizon
- Copper from the sea bed
What are examples of critical flow resources that need to be managed sustainably?
Water
Forestry
Soil
Why is the resource peak difficult to predict?
peak may be delayed
- technology makes new sources viable
- new reserves discovered
- new areas allowed
peak may come sooner - demand drops ( renewable or less economically viable)
- too difficult to extract
What are the challenges of the hubberts curve?
- attempting to measure the size and nature of future resource demand is difficult
- reserves are constantly reassessed as societies and technologies develop
What is the General pattern of oil consumption and production in the middle east?
Middle east has a surplus of oil - produce a lot but consume relatively little.
What is OPEC?
Orginisation for petroleum exporting countries they are a group of 13 countries who seek to control the supply of oil
What is the issue regarding LPG?
Middle east exports a lot of Liquid petroleum gas but Europe does not have the means to change it into agas
What is happening to world coal production?
Europe’s coal production is decreasing steadily as it is running out and environmental pressures grow.
China (the world’s biggest producer and consumer of coal is slowing their rate of consumption, mostly due to the air pollution it creates - but in the 2000s production in Asia Skyrocketed from the rapid economic development it experienced
What is the general pattern of global production and consumption of minerals like?
The USA consumes 20-30% of worlds global minerals but produce only 5%
In the past 50 years, developed countries have depleted their stocks and have imported from developing nations
Developed nations like Canada and Australia with excess minerals have increased their supply to fill this gap.
Since the 21st century, Asian consumption of minerals has increased, China has overtaken USA as biggest consumer of steel in the mid 2000s, consuming 25% of all steel by 2010.
Why is China consuming more steel and other minerals?
To provide for it’s large construction and development projects, like the Three Gorges Dam
Copper to create a national grid infrastructure for electricity
Aluminum consumption to provide for its growing manufacturing industries - but they still remain behind the EU and US in this regard.
What event caused a decline in global trade of steel?
The end of the cold war meant less was needed for armaments
What has China done that has led to a decline in steel and other metals?
Since 2014, Chinese economic growth has started to slow and they are embarking on less investment projects - they moved from being a net importer to a net exporter
What 5 factors have affected the trading of mineral ores?
- The inelasticity of certain metals with no substitute
- Recession and decreasing growth rates
- Falling prices mean less mining is occurring
- Technological change has reduced cost and increased supply
- Environmental concerns are discouraging exploration and exploitation leading to alternative, greener supplies
What are rare earth elements/metals?
Group of 17 elements that have similar properties that group them together in the periodic table. They tend to be together in abundant geological deposits, but once discovered they are often not viable to extract.
What are Rare earth Elements used in the production of?
- Electronic devices
- Catalytic converters
- Earth magnets
- EV’s Batteries
- Wind turbines
What will likely happen to the demand for REEs?
Increase as they are used in increasingly popular green technologies like wind turbines and EVs
What has happened to the market for REE’s throughout time?
Demand for REEs exploded with colour TVs in the 1960s and the USA controlled the market until the 80s until China undercut the market with lower prices until 2010 where they now control 95% of the market.
In 2010 they began restricting the selling of REEs causing panic buying creating an exponential increase in price
What are abundant metals?
Metals like iron and aluminum that can be found and usually extracted easily
What are Precious metals?
Rare metals in short supply that don’t oxidise like gold, silver and platinum
What are base metals?
a common metal that is not considered precious, such as copper, tin, or zinc. They often oxidise or erode easily
What are ferrous metals?
A metal that can be mixed with Iron
What is the biggest determiner in Coal’s geopolitics?
The impact it has on environment/ Climate change
What is a recent example of coal geopolitics?
As China (50% consumption) consumes less coal, producing countries like Australia suffer -> Aus has exported more to India as their demand grows
With the lack of Russian gas, Many EU countries like Germany and Poland have consumed more coal to meet the demand for energy, TMT Europe will be seen as hypocritical when they ask developing nations to reduce their emissions.
What is a recent example of Oil geopolitics?
To meet with the need for oil as an energy source following the Russian invasion of Ukraine, Biden went to the crown prince of Saudi Arabia to try persuading him to increase oil production despite Biden previously accusing him of authorising the murder of a Washington post Journalist.
What are the key issues facing minerals?
- Geopolitics
- Price volatility
- Globalisation
- Finite nature
What is the very general pattern for minerals?
Developing nations sell while developed nations buy (but developing nations demand is increasing).
What (regarding minerals) can create job losses in the UK and US?
The oversupply of cheap steel (dumping) from china flooding the market
What is neodymium?
A rare earth metal that is fairly abundant but difficult to get out of the ground. It is a part of the strongest magnet and the market for it is $11.3 billion
What is neodymium used for?
- Cellphones, headphones and other electronics
- Turbines
- Phone vibrations
What is happening to the Neodymium market?
Demand is on the rise, but 80% of it comes from China and 15% from AUS.
The main US supply mountain pass mine in California has been almost depleted.
However, following a dispute with the west, China limited supply and the price of Neodymium doubled from $100,000 to $200,000 per metric ton from 2010-2011
This has encouraged the US to start rebuilding the rare earth industry (diversification) - reopening the mountain pass mine
What are the issues of mining Neodymium?
Neodymium is often found by radioactive thorium and uranium which could be brought up with it. This is hard to store and damaging for the environment.
What are transboundary river basins?
River basins that are in more than one country which can lead to conflict as to who extracts the water
What are transboundary aquifers?
Aquifers that are in more than one country which can lead to conflict as to who extracts the water
What are the three water dispute examples?
- The Nile (Egypt, Sudan, Ethiopia)
- The Mekong River
- The Tigris and Euphrates River (Iran)
Explain the transboundary dispute on the Nile river?
Ethiopia built the grand renaissance dam that is the largest HEP provider in Africa on the Blue Nile. This can restrict the volume of water accessible to Egypt and Sudan. In a drought Ethiopia could store water for itself as Egypt and Sudan miss out on water.
Explain the transboundary dispute on the Mekong river?
A series of 80 new dams are choking the flow of the Mekong river which sustains 60 million people. The water level is much lower, with much less life in due to lost nutrients
Explain the water dispute of the Euphrates and Tigris river?
This is the cradle of humanity where humans first lived, and the city of Basra in South Iran contributes to 80% of Iran’s economy, However this key city does not control the flow of water in the north which belongs in Turkey, only 20% of normal flows reach the Euphrates in Iran, following the US invasion and Islamic state conflict. this has created a slower flow and water from the Persian gulf has inundated the river water.
What are the seven sources of water?
- Reservoirs
- river Abstraction
- Boreholes into the water table
- Snow and Glacier melt
- Desalinisation
- Water re-use
- Pumping from Aqufiers
What are reservoirs?
Manmade (but sometimes natural) lake used to supply water
Example of Reservoir as a source of water?
Welsh water obtains 95% of water from river abstraction or reservoirs thanks to the nation’s high rainfall and impermeable predominating rocks.
What are the disadvantages of reservoirs as a source of water?
Increased water loss from evaporation
lower flow rate downstream, particularly as reservoir is first filled
the reservoir may also silt up
What is river abstraction?
The removal of water from any source
Example of river abstraction?
Thames water serves london and the SE this way, with 70% of water coming from river abstraction
Negatives of river abstraction?
Reduces river volume and may return it as wastewater thus reducing qater quality
Negatives of river abstraction?
Reduces river volume and may return it as wastewater thus reducing water quality
What are boreholes into the water table?
Traditional wells sunk through permeable rock structures to penetrate the water table.
Example of Boreholes into the water table?
Thames water gets 30% of water through boreholes
Disadvantages of boreholes through the water table?
Lower water table can affect levels of usage
can affect natural habitats
Examples of Snow and glacier melt as a source of water?
60% of Iran’s freshwater for Urban industrial use and agriculture is from glacial melt
The gangs and Brahmaputra rivers flow across India from Glacial melt in the Himalayas
Disadvantages of Snow and Glacier melt as a source of water?
Climate change is causing glacial retreat and putting long term sustainability at risk
What is desalinisation?
Turning seawater into freshwater through (mostly) dual membrane osmosis.
Example of Desalinisation?
Israel produces nearly 40% of water through Desalinisation
Disadvantages of Desalinisation?
It is a very energy intensive (and therefore expensive) process.
Example of water re-use?
In the Valley of Mexico, 90% of all water used for irrigation is sourced from water re used from mexico city, which can also recharge groundwater supplies by irrigation
Disadvantages of Water re-use?
Much re-used water used is grey water and not potable (safe to drink)
What is pumping from aquifers?
Getting water from saturated rock below capped rock underlain by impermeable rock
Example of pumping from aquifers?
The Ogallala aquifer is the largest aquifer in the United States and stores as much water as lake Huron
Disadvantages of pumping from aquifers?
If water is abstracted faster than it is returned, aquifers will be depleted
Can create transboundary disputes
can lead to the salinsiation of soils if overused in areas with high evaporation rates.
Disadvantages of pumping from aquifers?
If water is abstracted faster than it is returned, aquifers will be depleted
Can create transboundary disputes
can lead to the salinsiation of soils if overused in areas with high evaporation rates.
What are the three factors affecting the quantity and quality of water availability?
- Climate -> Precipitation patterns, Temperatures affecting evaporation
- Geology -> Aquifers and the permeability of rocks
- Drainage -> Relief of the land, type of soil etc.
Describe the basics of the Murray Darling basin?
- Size of France and spain combined
- Covers 14% of Australlia from Queensland to Victoria
- Provides 75% of AUS water (85% of irrigation water)
- All key cities on the west coast rely on it for water
What has happened to water abstraction in the Murray Darling basin and what has this led to?
River abstraction has increased by 5x since the1920s - matching population increase
This has permanently damaged the mouth of the Murray Basin.
What are the Physical factors affecting the Murray Darling Basin?
- 480mm of rainfall annually
- additional groundwater extraction from the basin
- High evaporation on the Eastern edge of the Basin
- El nino can bring significant changes in Rainfall
Explain the basics of the river Thames/Thames water basics?
- Classed as having severe water stress, with the majority of easily accessible water supplies gone and having little spare capacity
- supplies 16billion litres of water to over 9 million people with a growing demand (Londoners use 10% more water than the average UK citizen)
How is climate affecting the water Supply of the Thames Basin?
- Average rainfall of 690mm (lower than the 900mm UK average)
- only 250mm of rainfall is useful for the environment and the population
- Frequent winter rainfall rather than storms allows for groundwater recharge over the winter months - it takes two below average winters for there to be a drought
How is climate affecting the water Supply of the Thames Basin?
- Average rainfall of 690mm (lower than the 900mm UK average)
- only 250mm of rainfall is useful for the environment and the population
- Frequent winter rainfall rather than storms allows for groundwater recharge over the winter months - it takes two below average winters for there to be a drought
How does geology affect the supply of the Thames Basin?
- The chalk surronding London provides base flow into the tributraries of the Thames and act as an aquifer
- 1/3 of the water of the Thames basins is pumped directly from Boreholes
- Many fountains use natural pressure to pump up
- as more is abstracted from the Thames pumps have been getting deeper and more expensive - reaching more than 200m deep
How does drainage affect the water supply of the Thames Basin?
- around 80% of London’s water is abstracted upstream from Teddington weir. The majority of London’s water is taken from aquifers, making groundwater the most important source. Tributaries arise from impermeable clay outcrops that result in overland flow.
- The other 20% not abstracted is from groundwater from aquifers.
What is water security?
Having enough water of suitable quality to meet a nation’s various needs
How much of Global demand is taken up for each sector?
Agriculture = 70% of water use
Industry = 22%
Domestic = 8%
How much of global water is used in agriculture?
70%
How much of global water is used in industry?
22%
How much of global water is used in domestic use?
8%
