resource management Flashcards
Food
When people can’t access enough safe, nutritious food, they can’t eat the right balance of nutrients. This can cause malnourishment.
Malnourishment can limit a child development. It also increases the likelihood of getting ill globally one third of all under fives die from diseases linked to malnourishment.
Water
People need to clean safe water for drinking, cooking and washing
Without proper sanitation, water sources, get polluted
Waterborne diseases, such as cholera and typhoid kill people
Water is needed to produce food clothes are many other products, so it is a big impact on peoples lifestyle
Energy
Some countries need energy for industry and transport as well as used in their homes. Electricity can allow people to develop industry, creating jobs and wealth. Lifestyles in higher income countries depend on large stable supply of energy.
Without electricity people in lower income countries may use other resources, burning words can lead to deforestation so people have to walk further find fuel
Electricity can also power pumps for Wales and provide safe of water
Global supply and unequal consumption
HIC- consumption of resources is greater in HIC is because they can afford to buy the resources they need and expect a higher standard of living
NEE- construction is increasing rapidly such as China industry is developing quickly and population and wealth are also increasing rapidly
LIC - consumption is lower in LIC such as you come there because they can’t afford to either exploit available resources or import lacking resources
Different type of food is becoming more popular
High-value foods- it’s peoples incomes have increased exotic fruits have become more popular these food are grown in LIC’s, and then exported to HICs
Seasonal products - seasonal food is only available during the months that agrees fruits and vegetables are important to meet us at mums for seasonal produce all year round
Organic products - people are becoming more concerned about the environmental impacts and how chemicals can affect health organic food production is strictly regulated some is produced in the UK, but lots is imported
Carbon footprint
- processing and packaging produces CO2. What is 10% of greenhouse emissions in 2017 came from agriculture.
- Transporting food produces CO2 the distance food is transported to the market is called food miles
- A carbon footprint is the amount of greenhouse gas produced. This causes global warming.
- Imported foods have to be transported along way
- People are becoming aware of environmental issues, so look for local sources of food
Farming becoming more industrialised
Since 1960s, there’s been a growth in agribusiness, which is a large-scale industrial farming.
This means that farms in the UK have been changing :
-From sizes have increased how many small forms have been taken over so food can be produced more cheaply
-Amount of chemicals used has been increasing (large amounts of artificial fertilisers and pesticides)
-Number of workers in please felt so just over 1.1% because of the greater use of machinery.
demand for water in the UK
The north and west of the UK has high rainfall to these are areas of water surplus. The south east and the Midlands have high population density is so these are in water deficit.
Since 1975, the amount of water used by households, it’s gone up by 70% (people have more appliances that use lots of water)
UK population is projected to increase by over 6,000,000 by 2040
Population densities are changing your plans to build new homes in the south-east where there is already a water deficit
Managing water pollution
Polices, although quality water reduces the amount available for use by putting pressure on water resources
- Nitrates and phosphates from crap fertilisers are washed into river and groundwater
-Pollutants from vehicles are washed into water by run off - Chemical and oil, spills from factories companies, local water sources
Up to 80% of water in England comes from ground water pollution is affecting the quality of nearly 50% of groundwater. Penny needs expensive treatment safe to use.
Strategies, include improving dream systems and imposing regulation
Water transfers
Transfer in the water from areas of surplus to areas of death, as it could be a solution
- Dams that I needed are expensive to build (Birmingham resilience project which will supply extra water is estimated to cost £300 million
-It can affect the wildlife that lives in the rivers
-They might be political issues people might not want a water to be transferred to another area
U.K.’s energy mix has changed
Traditionally, the UK has relied on fossil fuels. In 19 70,91% of our energy came from coal and oil.
Discovery of large gas reserves meant that in 19 80,22% of the U.K.’s energy was supplied by gas
There’s been a shift away from being fossils and towards renewable energy sources in 2014 19% of all electricity is generated from renewable sources
Wind and bio energy are the biggest source of renewable energy put the use of solar and hydroelectric has also increases
Coal oil and gas are running out
Reserves are swiftly being used up production has been declining since 2000
Coproduction has significantly decreased there’s been less demand due to effort to reduce emissions
The use of shale gas from underground is being considered as a way to adding resources. This is called fracking.
Economic issues with energy sources
-Extracting can be expensive and the cost of extraction increases as reserves run out. Northsea oil is especially expensive to produce
The cost to the consumer of electricity from nuclear I’m unable energy resources is relatively high
Money is needed for research into alternative energy and for initial investment. Domestic sources, don’t currently provide enough energy to meet them and see UK has to pay to import
Environmental issues with energy resources
The burning, the fossil fuels releases CO2 another greenhouse gases.
Fracking may pollute groundwater and cause mini earthquakes
Accident such as oil, spills Canley toxic chemicals into water soils on the atmosphere
Natural ecosystems can be damaged by renewable energy generators
Power stations and wind farms are considered to be visually intrusive
