resource management Flashcards
significance of water - food
without enough nutritious food people become malnourished which can prevent people from working or receiving education
significance of water - energy
a good supply of energy is needed for a basic standard of living. People need light and heat for cooking or to stay warm, it is also needed for industry
significance of water - water
people need a supply of clean and safe water for drinking, cooking and washing. Water is needed for food, clothes and other products
demand outstripping supply
the demand for resources like food water and energy is rising so quickly that supply cannot always keep up. Importantly access to these resources vary dramatically in different locations
supply and demand - population growth
current global population is 8 billion
global population has risen exponentially this century
global population is expected to reach 9 billion by 2050
with more people the demand for food water energy and jobs will increase
supply and demand - economic development
as LICs and NEEs develop further they require more energy for industry
development means more water is required for food production as diets improve
consumption definition
the act of using up resources or purchasing goods or produce
carry capacity definition
a maximum number of species that can be supported
changing technology and employment
the demand for resources has driven the need for new technology to reach or gain more resources
more people in the secondary and tertiary industry has increased the demand for resources required for electronics and robotics
food In the uk - growing demand
-The uk imports about 40% of its food, increases peoples carbon footprint
-growing demand for exotic foods all year round
-food from abroad is more affordable
-many food types are unsuitable to be grown in the uk
food in the uk - impact of demand
+ supports workers with an income and families in LICs
+taxes from farmers incomes contribute to local services
-less land for locals to grow their own food
-farmers exposed to chemicals
food in the uk - agribusiness
+intensive farming maximises the amount of food produced
+using machinery which increases the farms efficiency
-only employs a small number of workers
-chemicals used on farms damages the habitats
food in the uk - sustainable foods
-organic foods that have little impact on the environment and are healthier have been rising
-reduces emissions by only eating from uk
-supports local shops and farms
energy in the uk - demand
the uk consumes less energy than it did in the 1970s due to the decline of industry
energy in the uk - changes in energy mix
-75% of the uks oil and gas has been used up
-coal consumption has declined
-uk has become too dependent on imported energy
energy in the uk - energy mix
The majority of the uks energy mix comes from fossil fuels, want to switch to renewable resources that don’t contribute to climate change
energy in the uk - significance of renewables
+the uk government is investing more into low carbon alternatives
+renewable sources include wind solar and tidal energy
+uk government aims to meet targets for reducing emissions
-although infinite, renewables are expensive to install
energy in the uk - exploitation
+new nuclear plants provide job opportunities
+wind farm, locals have low energy bills
+reduces carbon footprint
-nuclear, problems with safety and possible harm to wildlife
-nuclear plants are expensive
-wind farm construction costs are high
-wind farms cause visual and noise pollution
water in the uk - growing demand
demand for water has risen due to:
-growing uk population
-water intensive appliances
-showers and baths taken
-industrial and leisure use
-watering greenhouses
water in the uk - pollution and quality
-chemical run off from farmland can destroy habitats and kill animals
-oil from boats and ships poisons wildlife
-untreated waste from industries creates unsafe drinking water
-sewage containing bacteria spreads disease
water in the uk - deficit and surplus
-the north and west have a water surplus
-the south and east have a water deficit
-more than half of England is experiencing water stress
water in the uk - management
-uk has strict laws that limits the amount of discharge from factories and farms
-education campaigns to inform what can be disposed of safely
-waste water treatment plans - remove dangerous elements to then be used for drinking
water in the uk - water transfer
-water transfer involves moving water through pipes from areas of surplus to areas of deficit
-high maintenance costs
-effects on land and wildlife
-amount of energy required
