Resource Managament Flashcards
What is the significance of food on economic and social well-being?
- lack of food could cause malnourishment
- malnourishment can cause increase of catching disease
- can also lead to underperformance in school meaning a lack of skills needed for economic development
What is the significance of water on economic and social well-being?
- necessary to clean, drink, cook and wash
- without sanitation water sources can become polluted
- water borne diseases are common
- having to walk long distances for water mean less time working and less economic development
What is the significance of energy on economic and social well-being?
- need energy for industry and transport
- energy in industry allows a country to develop
- people may use other methods of fuel without electricity causing negative environmental impacts
- can be needed to power wells and water sanitation
- lack of energy means people can’t travel for increased QoL
How is the global supply and consumption of resources uneven?
Some counties don’t have there own energy reserves
Some countries don’t have a climate suitable for food production
Consumption of resources depends on a countries wealth and availability
Consumption is increasing in NEE - China
Consumption is low in LICs because they can’t afford to import of export there own resources
Outline the three major changes in food production in the UK
Seasonal food all year round
Growing carbon footprint
More industrialised farming
Explain the growing demand for food imports?
- growing demand for seasonal fruits and vegetables that must be imported out of season
- increasing demand for high value foods like exotic fruit,veg and spice
- organic produce is increasing popular and lots of it needs to be imported
Why is the uks carbon footprint going as a result of food?
Growing, processing and packaging produces co2
Transporting food also produces CO2
imported foods have a larger carbon footprint because they have more food miles
More people are becoming aware of this and buying locally
How is UK farming becoming more industrialised?
Agribusiness has been growing
Small farms are taken over by large firms
Amount of chemicals used are increasing
Number of workers are falling due to increase in machinery
Industrial farming focuses on cost and quantity not on the environment
Outline the 3 major changes to the UK water resource
Demand for water varies
Water pollution needs to be managed
Water transfers help maintain supplies
How is the demand for water in the uk changing?
The north has smaller population densities and Hugh rainfall
The south has high pop densities and low rainfall
This created areas of water deficit and water surplus
Increase in water used per household because of appliances
Population increase in already dense areas
Why does water pollution need to be managed?
Polluted water reduces the amount available to use
Quality of uk river water has been improving but fertilisers are being washed into riders and chemical and oil spills
Pollution is effecting groundwater supplies
Strats include improving drainage systems and imposing regulations
How do water transfers help maintain supplies?
Transfer water from areas of surplus to areas of deficit
But transfers of water can causes issues
Dams are expensive and can distrust wildlife
How has the uks energy mix changed?
Traditionally the uk relied of fossil fuels
Use of nuclear energy increased since 1990
Recently there has been a shit away from fossil fuels
Wind and bio energy are the biggest sources of uk energy
What are happening to the uks fossil fuel supplies?
North Sea oil and gas reserves are rapidly being used
Uk still has coal reserves but production has fallen hugely
How is exploiting energy source causes issues in the uk?
Encomic
- extracting fossil fuels is expensive
- cost to produce energy from renewable sources is relatively high
- money need3d for research into renewable enrgy
Environmental
- greenhouse gases from fossil fuels
- oil spills or chemical leaks damage environment
Power stations and wind farms are considered eye sores
Describe global pattern of water surplus and deficit?
North America, Europe and parts of Asia are in surplus
Oceania, South America and Africa suffer from water deficit
Areas with high rainfall are in surplus like the Amazon rainforest
What does water security mean?
Water security means having access to enough clean water to sustain well being, good health and economic development.
What is water stress?
Water stress takes into account the accessibility, quality and scarcity of water
What are the reasons for increasing water consumption?
Changes in lifestyle and eating habits increase water usage per head
Global demand for food is growing, water is used for growing and processing
All energy sources require water, global energy consumption is constantly increasing a result of economic development
Outline the factors effecting water availability
Climate
Geology
Pollution of supply
Over abstraction
Poverty
Limited infrastructure
How does climate effect water availability?
Regions with high rainfall rainfall have a surplus but those with drier climates have less water availability
