Resource Security Flashcards
What is a reserve?
The part of the resource that is available/viable to extract under existing economic, political and technological conditions.
What is Primary Energy (with an example)?
Resources used in their natural form to produce power. e.g. crude oil, wood
What is Secondary Energy (with an example)?
Resources from converting a primary energy source into a new form e.g petrol, electricity, charcoal
Definition of Possible Resources
Thought to exist but not sampled
Definition of Inferred Resources
Identified but not measured
Definition of Measured Resources
Size measured and known accurately, grade, quality known to allow to determine as proven reserves
Definition of Indicated Resources
Size of the reserve partly measured and the extent estimated
What is a Resource?
Any aspect of the natural environment that can be used to meet human needs
What is Resource Security?
Ability to safeguard reliable and sustainable flow of resources to maintain a suitable standard of living and allow for ongoing social and economic development
What three factors does resource security involve?
Physical; economic and geopolitical
What are Stock Resources with an example?
Non-renewable; finite supply can be permanently expendings; quantity in absolute amounts; compound deposits e.g. fossil fuels
What are Flow Resources with an example?
Renewable; can be replaced in a sufficiently short time to be relevant to decision makers; annual rates e.f. freshwater, solar
What are is a Critical Flow Resource with an example?
Flows that are only renewable if human use remains at or or below their capacity to reproduce/regenerate e.g timber
What are renewable resources?
Continuous flow/ replaces itself
What are examples of critical renewable resources?
TImber (for charcoal/biomass)
What are the examples of non-critical renewable resources?
Solar/ wind/ tidal
What are non-renewable resources?
finite stock/supply
What is a recoverable reserve?
Amount of resources likely to be extracted for commercial use within a certain time period and at a certain level of extraction
What is a possible reserve?
Deposits thought to exist because geological terrain is similar to other areas that have yielded deposits but no exploration yet
What is the difference between a resource and reserve?
A resource is the entirety of a substance that can be used to meet human needs and a reserve is part of the resource that is economically, politically and technologically viable to extract.
