Sustainability Flashcards
Malthus hypotheses
population growth is faster than production of food
External pressure to food production
population growth, urbanization, economic development, globalization, climate change, water stress, envionmental degradation
triple burden of malnutrition
undernutrition, micronutrient defieciency, overweight
food system
input > production > processing > distribution > marketing > shoppinh > consumer > waste
sustainable nutrition
nutrition that is good for health & environment
3 methods for calculating environmental impacts of diets
1 life cycle assessment (LCA)
2 input-output analysis
3 integrated assessments
life cycle assessment
determine the foodprint for the different sectors. Remember the video of the guy with the strawberry yoghurt drink. Every stepp in the cycle is important.
input-output analysis
involves use of aggregate sector level data on how much environmental impacts can attributes to each other. Remember the input-output table video.
integrated assessments
global equilibrium models. Multiple segments are moddeled into one framework. Often used with policy.
Eating insects could save the world because:
a. The need little water
b. They are warm blooded
c. They deliver carbohydrates while eating little food
a the need of little water

a. Acidification
b. Water storage
c. Land use
c land use
- Which molecule has the highest greenhouse warming potential?
a. CO2
b. N2O
c. O2
b N2O
- The food system currently uses:
a. 30% of all ice-free land
b. 50% of all ice-free land
c. 70% of all ice-free land
30% of land
70% of water
2 environmental indicators in relation to diet
1 resource depletion 2 pollution (verontreiniging)
Benefits of soil
1 basis for healthy food production
2 host a quarter of biodiversity
3 help to combat and adopt climate change
4 essential for food security, store and filter water
