Section C - Resource Management

Question 1

what is a resource

Answer 1

a resource is a stock or supply of something that has a value or a purpose. The tree most important resources are food, water and energy. Adequate supplies of these resources are essential for countries to develop

Question 2

how are water, food and energy distributed across the world

Answer 2

most HIC’s have plentiful supplies and enjoy a high standard of living. Poorer countries lack resources and struggle to progress or improve quality of life for their people. As the world’s population continues to grow, resource management will present many challenges

Question 3

why is food important

Answer 3

a poorly balanced diet can cause illness and diseases. People need to be well fed to be productive. Obesity is an increasing

Question 4

what are the global inequalities of food

Answer 4

Over one billion people do not get enough calories. Undernutrition affects two billion. Countries in sub-Saharan in Africa suffer most from undernutrition

Question 5

why is water important

Answer 5

essential for drinking. Vital for crops. Used to produce energy

Question 6

what are the global inequalities of water

Answer 6

variations in climate and rainfall affect supplu. Capture, storage and extraction is expensive. Many poor countires have water storage. LICs/NEEs use most water for agriculture. HICs use most water in industry

Question 7

why is energy important

Answer 7

needed for light, heat and power. Powers factories. Provides fuel for transport

Question 8

what are the global inequalities of energy

Answer 8

Richer countries consume more energy than poorer countries. The Middle East is a major oil supplier; its own consumption is low. As Nees become more industrialised, the demand for energy will increase

Question 9

how is demand for food changing in the UK

Answer 9

the UK imports about 40% of the total food it consumes. This percentage is rising

Question 10

why does the UK import so much food

Answer 10

demand for more exotic foods and seasonal produce all year round. Availability of cheaper food from abroad. Uk climate is unsuitable for production of some foods

Question 11

what is the impact of importing food

Answer 11

food can travel long distances. Importing food also adds to our carbon footprint. This comes from producing the energy from commercial cultivation and from transport

Question 12

how is the UK responding to challenges with food

Answer 12

people are being encouraged to eat locally produced foods according to season. Two recent trends in the UK farming are agribusiness and organic produce

Question 13

facts about the Lynford House Farm in East Anglia (an agribusiness)

Answer 13

the land intensively farmed, maximising the amount of food produced. Peticides and fertilisers are widely used. Machinery costs are high but increase efficiency. A small number of wokers are employed

Question 14

facts about Riverford Organic Farms

Answer 14

Began as an organic farm in Devon. Now delivers organic vegetables from farms in Devon, Yorkshire, Peterborough and Hampshire. This reduces food miles and provides local employment

Question 15

what are the demands for water in the UK

Answer 15

almost 50% of the UK’s water supply is used domestically. Demand for water in the UK is estimated to rise by 5% between 2015 and 2020 because of rapid growing population, more houses and an increase in the use of water-intensive domestical appliances

Question 16

How far does the UK’s water supply meet demand

Answer 16

the north and west have a water surplus, where supply exceeds demand. The south and east have water defict, where demand exceeds supply. Water stress (where demand exceeds supply) is experienced in more than half of England

Question 17

how is water quality and pollution managed

Answer 17

The Environmental Agency manages water quality by: filtering water to remove sediment, purifying water by adding chlorine, imposing strict regultaions. Some groundwater sources have been polluted by: industrial sites discharge, agricultural chemical fertilisers, leaching from old underground mines

Question 18

why might water transfer be opposed

Answer 18

it has an effect on land and wildlife, it is expensive and greenhouse gases released by pumping water over long distances

Question 19

how has the UK’s energy mix changed

Answer 19

energy consumption has fallen in the UK in recent years, mainly due to decline in of heavy industry and energy conservation. By 2020, the Uk aims to meet 15% of its energy requirement from renewable sources. 1990 - non renewable fuels, 2007 - coal, gas, nuclear, 2014 - wind and solar

Question 20

why has the UK’s energy mix changed

Answer 20

about 75% of the Uk’s known oil and natural gas reserves have been used up. Coal consumption has declined because of concerns of greenhouse gase emissions. The UK’s enegry security is affected as it becomes increasingly dependent on imported energy. However fossil fuels are likely to remain positive in the future because: coal imports are cheap, shale gas deposits may be expolited in the future

Question 21

what are some economic impacts of nuclear energy souce expolitation

Answer 21

nuclear power plants are expensive to build. Decommissioning old plants is expenive. New plants provide job opportunities

Question 22

what are some environmental impacts of nuclear energy souce expolitation

Answer 22

problems of safe processing and storage of radioactive waste. Warm waste water can harm local ecosystems

Question 23

what are some economic impacts of wind farms

Answer 23

high construction costs. Local homeowners can have lower energy bills

Question 24

what are some environmental impacts of wind farms

Answer 24

visual impact on the landscape. Help reduce carbon footprints. Noise from wind turbines
