THESIS: Ensuring food security for future global populations will be difficult
Notes
Big ideas in question
Population growth:
Describe: projected to reach 9-10 billion by 2050...; mainly in developing countries
Explain population growth: High fertility rates (access to contraception, cultural reasons) + reduced mortality rates (reasons)
Food security:
exists when all people, at all times have access to sufficient, safe and nutritious food to meet their dietary needs and food preferences for an active and healthy life...
A range of theses
It will be challenging to feed future global populations
We won't be able to feed future global populations
Ensuring food security for future global populations will be difficult
We will be able to feed future global populations
Not all biomes are suitable for food production
Describe how much land is available for agriculture; which biomes; how do the 4 spheres interact? What climate conditions are necessary?
Refer to maps
Climate change may make some biomes suitable to agriculture
What is climate - Explain how it occurs - Which biomes and what possible changes?
Humans are able to increase food production
The Green Revolution: we have been able to respond to population pressure in the past
Describe the Green Revolution: what were the pressures and where?
Explain the GR: 4 factors - innovation, science, changing the agricultural system; agribusiness, increasing land area
What were the outcomes?
Innovation hasn't always been successful
The Green Revolution - Produce from genetically modified grains were low in minerals and vitamins; Some techniques led to land degradation.........
Current agriculture is reducing the amount of fertile land
Desertification: describe, explain, draw out effects
There will many future challenges to food production
Climate change, desertification, fossil fuels, scarce phosphate
We can innovate....
We will be able to feed future global populations
