   [92,614Mt CO2e]
2. Rice cultivation - 18.5%
   [23,432 Mt CO2e]

Answer 7

Methane is 86x (in 20-yr window)
Methane is 34x (in 100-yr window)

Question 8

Major Ag GHG

Answer 8

Methane from EF
N2O from fertilizer nitrification
[above two total 65%]
Rice cultivation
Manure management
Crop residue burning

Question 9

Biggest opportunities in Ag

Answer 9

1. Changing farming practices
   -Fertilizer mgmt
   -Conservation tillage
   -Rotational grazing
   -Restoring degraded lands
2. Changes in diets
   3, Food loss management

Question 10

What’s WRI solution - 5 course meal - 22 solutions

Answer 10

1.Reduce/Change demand growth (incl. food loss reduction)
2. Food production UP w/o new land
3. Increase fish supply
4. Reduce Ag GHG emission
5. Protect/restore natural ecosystems

Question 11

WRI main foci

Answer 11

1. Plant base meat
2. Post harvest work to increase shelf life
3. Supressing enteric fermentation
4. Nitrification inhibitors in soils
5. N-absorbing crops (gene modification)
6. Low methane rice
7. Use CRISPER to unlock desirable traits more yields
8. High yield palm oil
   9 Algae based fish feed
9. Solar powered fertilizer (Note: 85% of GHG relating to fertilizer prod is coming from H2 production alone)

Question 12

Global Land-Ocean

Answer 12

Land - 29% -149 M sqkm
Ocean - 71% - 361 M sqkm

Question 13

Global Land USE

Answer 13

71% is habitable - 104 M sqkm
[rest is glaciers and barren land]

Half of that is Agric. [51 Msqkm]
Of the above:
23% [11Msk] goes for crops for human food
77% [40 Msk] goes for livestock and crops for animal feed.

Question 14

What is US GHG emissions and Ag contributions in Gt

Answer 14

2020-base 6.8 Gt = 6,769 Mt COe
Ag contributes 11% = 0.7 Gt
(Energy, Transport, Industry - approx 25% each; residential-13%; Ag-11%; USEPA)

2050 = 9 Gt baseline
2050 = 11.2Gt no productivity gains post-2010

Question 15

GHG by country

Answer 15

USA 14.04 t/cap/yr
China. 7.69
India 1.75
