GHG Emissions from Food System

Question 1

What happens if the Earth warms by 4C?

Answer 1

Extreme event would happen every year our of 10 years

Question 2

How long would it take for the same temperature difference that happened in the early Eocene to happen in the worst case scenario?

Answer 2

500 years

Climate change is happening at a much faster rate and evolution can’t keep up

Question 3

What is the problem with the agricultural sector in the NC sectors?

Answer 3

Only counts food production

Making fertiliser and food products e.g. bread comes under business emissions

Question 4

What is Haber Bosch?

Answer 4

Produces around 450million tonnes of nitrogen fertiliser per year

Consumes 3-5% of the worlds gas production

Estimated 6.6.kg CO2 produced for each kg N fertiliser produced

WOULD NOT COME UDNER AGRICULTURAL EMISSIONS

Question 5

How much is agriculture responsible for all non-CO2 emissions?

Answer 5

1/2

Question 6

What countries are the largest emitters of GHGs? What is the problem with this?

Answer 6

China, USA, Russia, India and Brazil

Should not proportion GHGs by country - larger populations would have more GHG emissions

Question 7

What is predicted to happen to global agricultural emissions?

Answer 7

They will increase

Question 8

How much of sub source emission are from manure and enteric?

Answer 8

Manure = 19%

Enteric = 81%

Question 9

What was the green revolution?

Answer 9

Fertiliser become more affordable

Crops became smaller and less prone to damage and these factors produced more food
