when people at all times have access to sufficient, safe, nutritious food to maintain a healthy and active life

being without reliable access to sufficient, affordable, nutritious food

a widespread, serious shortage of food; in the worst cases leading to starvation and death

when people do not consume enough nutrients to cover their needs for energy and growth, or to maintain a healthy immune system

Global patterns of food security

Geography

Food resources: demand and supply

Strategies to increase food supply

Sustainable food production

Using GIS desire lines to visualise and analyse food miles

This unit, comprising of three variants, teaches pupils about global inequalities in food, water and energy production and consumption. Pupils learn about resource security and about sustainable futures.

Global pattern of resources

a long period of time with little or no rainfall, leading to a shortage of water

applying water to land in order to supply crops and other plants

occurs when the demand for water exceeds the available amount during a certain period or when poor quality restricts its use

more than lack of income, it includes hunger and malnutrition, limited access to education and other basic services

growing plants using mineral nutrient solutions in water and without soil

growing plants in a mist environment without the use of soil

use of technology to modify organic products or processes, for example, genetically-engineering crops

approach to boosting food production that seeks to benefit poor farmers bypassed by the original green revolution and conserve the environment

technology suited to the needs, skills, knowledge and wealth of local people in the environment in which they live

when food is produced in ways that avoid damaging natural resources, provide social benefits and contribute to local economies

when food is grown without the use of artificial chemicals, such as fertiliser and pesticide

a system of farming based upon or directly using patterns and features observed in natural ecosystems, such as increased biodiversity and intercropping

the growing of crops and the raising of animals in towns and cities; includes processing and distributing food, as well as collecting and reusing food waste

the distance food items travel from their point of production to the point of consumption (not necessarily measured in miles)

a graphical technique using lines on a map to show the simple direction of movement from one place to another

straight line routes which appear curved on 2D maps because they account for the curvature of Earth

in GIS, a read-only display of attribute information (e.g. text, images, charts) often linked to a location
