Terms in this set (34)
application of business skills to agriculture.
the manipulation (through genetic engineering) of living organisms to produce useful commercial products (such as pest-resistant crops and new bacterial strains).
a measurement of all the greenhouse gases we individually produce, through burning fossil fuels for electricity or transport expressed as tonnes (or kg) of carbon dioxide equivalent.
consumer's willingness to pay for specific products. Consumer demand in the UK affects what is imported from other countries.
reducing energy consumption through using less energy and becoming more efficient in using existing energy sources.
the amount of energy that is used during a given period, normally one year. Most often, it is calculated as the average amount of energy consumed per head of population of a country, region or city.
developing and using energy resources to the greatest possible advantage, usually for profit.
the difference between a country's rising demand for energy and its ability to produce that energy from its own resources.
a situation where a country has to rely on others to supply most of its energy. This dependence makes a country politically vulnerable.
the range of energy sources of a region or country, both renewable and non-renewable.
a widespread, serious, shortage of food. In the worst cases it can lead to starvation and even death.
being without reliable access to a sufficient quantity of affordable, nutritious food. More than 800 million people live every day with hunger or food insecurity.
the distance covered supplying food to consumers.
when people at all times have access to sufficient, safe, nutritious food to maintain a healthy and active life.
energy generated by heat stored deep in the Earth.
wastewater from people's homes that can be recycled and put to good use. Uses include water for laundry and toilet flushing.
regulation and control of water levels, pollution, ownership and use of groundwater.
the key resources of food, water and energy which influence all elements of human well-being.
Local food sourcing
a method of food production and distribution that is local, rather than national and/ or international. Food is grown (or raised) and harvested close to consumers' homes, then distributed over much shorter distances.
the energy released by a nuclear reaction, especially by fission or fusion. Nuclear energy uses fuel made from mined and processed uranium to make steam and generate electricity.
food which is produced using environmentally and animal friendly farming methods on organic farms.
when water is used more quickly that it is replaced.
sewage water that has been treated to remove solids and impurities so it can be recycled.
the control and monitoring of resources so that they do not become depleted or exhausted.
the Sun's energy exploited by solar panels, collectors or cells to heat water or air or to generate electricity.
Sustainable energy supply
energy that can potentially be used well into the future without harming future generations.
disputes between different regions or countries about the distribution and use of freshwater. Conflicts arise from the gap between growing demands and diminishing supplies.
the preservation, control and development of water resources, both surface and groundwater, and prevention of pollution.
water stress occurs when the demand for water exceeds the available amount during a certain period or when poor quality restricts its use.
this exists where water supply is greater than demand.
water transfer schemes attempt to make up for water shortages by constructing elaborate systems of canals, pipes, and dredging over long distances to transport water from one river basin to another.
diseases caused by microorganisms that are transmitted in contaminated water.
electrical energy obtained from harnessing the wind with windmills or wind turbines.
or hydraulic fracturing, is the process of extracting natural gas from shale rock layers deep within the earth.
