Unit 2 - AOS 2 - Food security Flashcards
Definition of food security
“When all people, at all times, have physical and economic access to sufficient, safe and nutritious food meets their dietary needs and food preferences for an active and healthy life”.
Dimensions of food security AAUS
- availability of food
- Accessibility (economically and physically)
- Utilization (the way it used and assimilated by the human body)
- Stability of these three dimensions
Global hunger Index
GHI = tool to measure and track hunger a regional, national and global level.
Four indicators to calculate GHI
- UNDERNOURISHMENT: calorie intake
- CHILD WASTING (acute undernourishment): children under 5yrs who are wasted (low weight for their height)
- CHILD STUNTING (chronic undernourishment): children under 5yrs are stunted (low height for age)
- CHILD MORTALITY: children under 5yrs in fatal mix of inadequate nutrition and unhealthy environments
How is GHI scored
Each four component indicators is given a standardized score on a 100 point scale based on highest observed level for the indicator on a global scale in recent decades.
Factors that negatively influence food security
- Conflict
- Scarcity of arable land
- Economic development
- Population growth
how does conflict (war) impact growth of food?
- War destroys farmland when it is bombed making it unusable and unsafe for crop growth
- Ammunition often contains poisons which destroy croplands
How does conflict (war) impact access to food?
- Fighting for resources means there are those who have and those who have not
- How it can be harvested or transported to markets.
Scarcity of arable land and how it impacts food security
“Arable land is land that can be used to cultivate crops or raise livestock”
Desertification reduces the amount of arable and we have access too (–> due to vegetation clearing & intensive farming of land)
How does Economic development and Global population growth impact food security? (diet?)
Increasing populations means more food required.
-> as countries become more economically westernized = adopt western diet. (meats)
(as a result, increases deforestation and decreases arable land and biodiversity)
How does climate change effect food security?
- Increase in temperature and extreme weather conditions impacts crops and livestock.
(reduces food supply for people and livestock)
