Q

How is food essential to human development?

A
  • needed to fuel our bodies and malnourishment increases the likelihood of getting disease, can affect peoples development
  • provides nutrients, nutrients provides energy for activity, growth and general functions of your body
  • healthy balanced diets, lead to people enjoying themselves, have fewer infections, and other illnesses

Q

How is the global distribution of the world described?

A

It’s described as uneven

  • some countries don’t have energy reserves, others have dry climates or environments that aren’t suitable for food production
  • countries without resources have to import them or find technological solutions, therefore consumption of resources depend on the wealth of a country and their availability for resources

Q

What happens to resource demand as the development and income of a country increases?

Q

What are the global inequalities in the supply and consumption of food?

A

-temperature & precipitation levels can affect food production
E.g. droughts cause crops to fail, most plants grow most effectively between 20-28°C, best soil is a rich, sandy loam
-farm technology can increase the ability for more food resources
E.g. Combine harvesters
-food demand affected by social factors-due to increased disposable income and a high quality diet
-the increase in the worlds population is increasing the demand for food

Q

How does importing food increase the UK’s carbon footprint?

A
  • the transport used to import food increases the UK’s carbon footprint
  • some crops require more intensive treatment so the machinery used effects the carbon emissions produced to make that food
  • the emissions for creating a food product in the U.K. by having to use e.g. Greenhouses can sometimes outweigh the emissions of importing it
  • food transported by plane create a lot more carbon emissions than being transported by boat

82
Q

Why is it difficult for Nepal to import coal and oil?

A
  • land locked no ocean/sea ports difficult to import fossil fuels
  • LIC so has limited money to import fossil fuels
83
Q

Why is Nepal well suited to development of micro-hydro plants?

A

It’s mountainous because it’s based on the Himalayas and it has high rainfall and melting glaciers which provide a large constant supply of water and it has fast flowing rivers with big drops

84
Q

How does micro-hydro plant benefit agriculture?

A

Agriculture is improved because animal and crop waste is no longer used as a fuel but put back on land as a fertiliser

85
Q

Why is the scheme in Nepal sustainable?

A

It’s run and built by the local community, so the community can maintain their supply. Water won’t run out. Produces no carbon dioxide or other pollutants so that makes it sustainable.

86
Q

What are the social impacts of the micro-hydro dam in Nepal?

A
  • improved school facilities
  • health care has improved because refrigeration allows storage of medicine
  • reduced risk of fire because kerosene lights and candles aren’t necessary
  • reduced rural to urban migration
87
Q

What re the economic impacts of the micro-hydro dam in Nepal?

A

Business developments are made possible which creates more jobs and more money will go back into the local community.
