**6. Analysis of agriculture connections with exceedances of planetary boundaries**

**Table 3** indicates that agriculture is a major source of GHGs with a repartition of 24%. This share does not tell the whole story because GHGs do not all have equal impact on global warming potential (GWP). As **Table 1** shows, on a one-hundredyear time horizon, CH4 would exert 25 times the GWP of CO2; and N2O, 298 to 320 times. Hence impact of a sector on climate change is related not only to the ratio of GHG but also to the proportion and potency of constituent GHGs. Also, **Table 3** did not disclose any information on the other climate forcer; aerosols. We will now take a closer look at agricultural connections with GHGs and aerosols.
