Resource Management Flashcards
What are the three essential resources for life and development?
Food, water, and energy.
Why is resource consumption increasing globally?
Population growth, economic development, higher living standards.
What is resource insecurity?
When people do not have reliable access to enough food, water, or energy.
What are the global inequalities in energy supply?
HICs consume more energy per person; LICs may lack infrastructure/resources.
Name two reasons for uneven global energy supply.
Unequal resource distribution, political instability, poverty, conflict.
How is the UK reducing energy demand?
Energy-efficient homes/appliances, smart meters, public awareness campaigns.
What % of UK energy came from renewables in 2022?
Around 42% (wind, solar, biomass, hydro combined).
What are the UK’s energy mix trends?
Decline in fossil fuels, rise in renewables, debates over nuclear and fracking.
Why is energy security important for the UK?
Reduces reliance on imports, protects against global price shocks.
Give one issue with renewable energy in the UK.
Expensive to install, can be unreliable (e.g. wind/solar), impacts landscapes.
Why does Nepal need sustainable energy solutions?
Remote mountain villages, lack of grid access, reliance on wood fuel.
What is a micro-hydro scheme?
Small-scale hydroelectric power plant using river water and gravity.
Benefits of micro-hydro in Nepal?
Clean, cheap, local energy; powers homes, schools, small businesses.
How do micro-hydro schemes help development?
Reduce deforestation, improve education/health, support businesses = income.
Why are micro-hydro schemes sustainable?
Use local materials/labour, no emissions, minimal environmental impact.
Challenges of micro-hydro in Nepal?
Cost to build, maintenance needed, depends on rainfall.
Where is Epping Forest located?
Northeast of London, on the border of Essex.
What kind of ecosystem is Epping Forest?
Temperate deciduous woodland.
Give 2 examples of interdependence in Epping Forest.
Nutrients from leaf litter feed soil → trees grow → provide shelter for insects.
How is Epping Forest managed sustainably?
Conservation areas, tree felling rotation, public education, habitat protection.
Why is energy demand rising globally?
More industry, more technology, population growth, higher standards of living.
Evaluate the sustainability of Nepal’s micro-hydro energy.
Environmentally friendly and community-led, but limited to small areas and requires maintenance.
Why is energy mix a challenge for countries like the UK?
Need to balance cost, reliability, environment, and political pressures.
Why are fossil fuels still used despite climate concerns?
Infrastructure already exists, they are reliable, and renewables can be expensive or unreliable.
