Food security
When all people, at all times, have physical, social and economic access to sufficient, safe and nutritious food that meets their dietary needs and food preferences for an active and healthy life.
Energy security
When all people, at all times, enjoy the uninterrupted availability of energy they require to meet their needs, and at an affordable price.
Extreme poverty
When a person's income is too low for basic human needs to be met, potentially resulting in hunger and homelessness (living with less than $1.90 a day)
New Global Middle Class

Relative poverty
When a person's income is too low to maintain the average standard of living in a particular society.
Ecological footprint
A crude measurement of the area of land or water required to provide a person or society with the energy, food and resources needed to live, and to also absorb waste.
Carrying capacity
The maximum number of people an area of land can support with current levels of technology.
Renewable resources
Natural resources that are replenished by the environment over relatively short periods of time.
Non-renewable resources
Mineral and fossil fuel resources that are available only in limited supplies.
Embedded water
A measure of the amount of water used in the production and transport to market of food and commodities. (virtual water, water footprint)
Nutrition transition
A change in diet from staple carbohydrates towards meat and fish proteins and dairy products.
Energy mix
The proportions of hydrocarbons, renewable energy sources and nuclear energy that a country uses to meet its domestic needs.
Hydrocarbons
Fossil fuels, contain a mix of hydrogen and carbon.

WFE nexus
The complex and dynamic interrelationships between water, energy and food resource systems.
Safe water
Water that is safe to drink or to use for food preparation, without risk of health problems.
Food availability
Sufficient quantities of food of appropriate quality to support a population, supplied through domestic production or imports, including food aid.
Energy pathways
Flows of energy that link producer regions with consumer regions.
(Physical form = pipelines, electricity power lines)
Water scarcity
When the annual supply of water directly available per person falls below 1,000 cumecs.
Peak oil
The point when the maximum rate of global oil production is reached
Stewardship
