PAPER 2 - The Challenge Of Resource Management Flashcards
What is a resource?
A stock or supply of something that has a value or purpose
How is food significant for our wellbeing?
Nutrients, vitamins & minerals - keep you healthy
Calories - fuel for our bodies
We need them to work & enjoy ourselves
How is water significant for our wellbeing?
Drink for survival
Wash & dispose waste
Grow & process food
Wash clothes
How is energy significant for our wellbeing?
Make bricks
Heat homes
Transport us
Power machinery
Process food
What is the global distribution of food?
Disparity between average calorie consumption in HICs and LICs
UK - 3200 per person
Somalia - 1580 per person
What is the global distribution of water?
Global average water footprint - 1240 litres
USA - 2483 litres
Bangladesh - 896 litres
What is the global distribution of energy?
Richest 1 billion in the world consume 50% of the world’s energy
Poorest 1 billion consume only 4%
How has the demand and supply of food in the UK changed?
Before supermarkets - food was seasonal & sourced in the uk
We now eat exotic fruit & veg year round
We import food via sea & air (even if it can be grown in the uk) because it is cheaper
This impacts good miles & carbon footprint
What is Food security
What are Food miles
What is Carbon footprint
What is Agribusiness?
What is Organic Produce?
Agribusiness = Intensive farming aimed at maximising the amount of food produced using modern technology and chemicals.
Organic Produce = Local and seasonal foods grown without the use of chemicals.
Agribusiness - Lynford House Farm
570 hectares
Intensely farmed to maximise productivity & profitability
Main crops produced - Wheat, Sugar beet, & Potatoes
Employ a small number of workers
Chemicals are widely used as Pesticides & fertilisers
Addressed frequent water shortages by investing in a 54 million litre reservoir
Riverford Organic Farms
Regional farms in Devon, Yorkshire, Peterborough, & Hampshire
+ Reduce food miles
+ Support local farmers
+ Provide local employment
+ Build a strong link between grower & consumer
- Expensive
- Less output or food
- Seasonal food only
How has the demand and supply of water in the UK changed?
Increased because:
• growing population
• more houses being built
• increase in the use of water intensive domestic (e.g. washing machines)
How is water supply distributed in the uk?
North & west of UK = water surplus
High rainfall & relatively low population density
South & east of UK = water deficit
Low rainfall & high population density
Saving water
• using domestic water meters to keep track of water usage
• increase the use of recycled water
• use efficient domestic appliances which use less water
• grey water (waste from people’s homes) can be used to irrigate crops
Transferring water
• water is transferred from areas of water surplus to areas of water deficit
There is opposition to large scale schemes due to:
• high costs
• destroying habitats
• pollution from greenhouse gases needed to pump water
How has the demand and supply of energy in the UK changed?
