Resource Management Flashcards
What areas have a surplus of food
much of Europe, Asia, North + South America
Why might an area have a surplus of food?
moderate climate, fertile soils, advanced tech
What is it called when you don’t receive the basic nourishment required?
undernourishment or undernutrition
What areas are prone to water shortages and deficits?
Africa and Middle East
Is the UK an efficient producer of food?
yes - fertile soils, plenty of rainfall, mild temps, advanced tech
Does the UK have a sufficient water supply?
surplus in NW, deficit in SE - rarely an issue
Does the UK have sufficient energy supply?
large fossil fuel resources, several nuclear power plants, great potential for renewable due to appropriate climate
What are the changing Uk food demands?
organic produce, seasonal produce, local food
Why is there a demand for high-value food exports?
variety of produce in and out of season
Give 2 examples of high-value foods.
specialist honey or Madagascan vanilla
What are the positives of organic food?
fewer/ no pesticides, no fertilisers (less runoff), reduces disease in animals
What are the disadvantages of organic food?
expensive - farmers may have a lower yield (not all people can afford it)
Why has agribusiness become a trend?
increases yields, lowers costs - combining small farms into a large farm
What are the positives of local food?
creates jobs locally, sense of community, reduces pollution from food miles, products may have a higher nutritional value
What are the negatives of local food?
less variety (less cultural mix and diversity), difficult for those in cities, more expensive for consumers
How can we increase water supply nationally?
water transfer schemes, encourage people to conserve water, create reservoirs
How can we manage water quality in the UK?
green roofs and walls, pollution traps, waste water treatment, desalinisation plants
What are the advantages of fossil fuels?
creates jobs, reliable energy
What are the disadvantages of fossil fuels?
burning of fossil fuels release greenhouse gases, imported from other countries (e.g. Russia, gas)
What are the advantages of renewables?
lower carbon emissions, offshore wind turbines can create habitats, jobs in research + development
What are the disadvantages of renewables?
high set up cost, only suitable in some climates, can disturb wildlife
Why is water important for well-being?
farming, industry, dispose waste, sustain life
Why is energy important for well-being?
machinery (agriculture), domestically - electricity, heating, light
Why is the global demand for food increasing?
-population growth
-economic development (more people with disposable income, more imports)
