Food security Flashcards
what is food security?
when people have affordable and nutritious food to eat
What is malnutrition?
consuming an unsuitable amount of energy, protein and nutrients
What is under nutrition?
consuming too little food- leading to a loss of body weight
What is the depth of food deficit?
difference between av. food consumption and av. food requirements (surplus and deficit)
3 methods to reduce food insecurity
increasing food production, access and reducing waste
increasing food production methods
agricultural expansion- convert for use
Changing types of food produced-plants need less water than dairy- arable farm produces more
GM technology- higher resistant yields-less pesticides
Hydrophonics- plants grow in nutrient solution and not soil (infertile soil is irrelevant)
increasing food access methods
Trade- need low prices, may undercut farmers
Aid
Improve access to markets- transport infrastructure
Reducing waste methods
Production-educate farmers how to reduce pests
Distribution-improve shop storage and donate
Consumption- ‘Think.Eat.Save’ campaigns- share recipes to use leftovers
3 food security pillars
food access, availability, utilisation
Food security solutions in LICs
2 billion eat insects- high fat and protein-take up less space
ONLY ACHIEVED ON SMALL SCALE
Food security solutions in MICs
Green revolution- train farmers in sue of new tech and practices
Food security solutions in HICs
Aquaphonics- water is recycled- limited electricity access, limited yield
‘Love food hate waste’ eat leftovers, buy in
Lab grown meat- £18000/lb of meat
Vertical farms- decreases energy costs by 80% increases yield by 200%
GM crops- could cause other health issues
