The challenge of resource management - Overview Flashcards
what is a resource?
It is a stock or supply of something that has value or purpose
what are the most important resources for human development?
- food
- water
- energy
what global inequalities come with food?
- more than 1 billion don’t consume enough calories
- about 2 billion are malnourished/undernourished
- there can still be hunger even in countries that produce lots of food
what global inequalities come with water?
- supply affected by rainfall + climate variations
- capture, storage and extraction are expensive
- poor countries often have water shortage
- LICs/NEEs main use = agriculture
- HICs main use = industry
what global inequalities come with energy?
- rich countries use more energy than poor countries
- Middle East supplies lots of oil - consumes very little
- when NEEs become more industrialised, energy consumption will increase
why do resources need managing?
- limited supply + unevenly distributed
- growing demand - rising population, rising incomes, new technologies
- can be used as political tool - eg. trade can be affected by geopolitics
- cross-boundary nature of resources - potential conflict
- often found in environmentally sensitive areas
how can we reduce consumption of resources?
- shower instead of bath and take shorter showers
- change diet - more plant-based + sourced locally/seasonally
- avoid fast fashion/buy second hand
- use more energy efficient appliances
Where does the UK source its water from?
- groundwater supplies (aquifers)
- reservoirs
- rivers
Describe the domestic use of water in the UK
- over half of water usage is in the bathroom - 30% toilet flushes, 20% baths, 12% showers
- 5% of water lost through leaks - aging infrastructure
how is water demand changing in the UK?
Demand is already high and by 2034 demand might exceed supply - sped up by climate change
Reasons:
- population increase + more houses
- more domestic appliances used - eg. washing machine
- irrigation demand increased
- aging infrastructure - more water is lost to leaks (21% of water demand comes from leaks)
describe water supply distribution in the UK
- the north and west have a water surplus - supply exceeds demand
- the south and east have a water deficit - demand exceeds supply
