The methods presented in the SIT were applied to forecasted livestock populations in order to estimate emissions. Emissions from both enteric fermentation and manure management are dependent on livestock populations. Forecasted changes to livestock populations based on post- recession totals show that there will be very little growth in Nevada's population of livestock. Forecasting the emissions from the agricultural soils and agricultural residue burning sub-sectors shows similar results. The data from these forecasts show a relatively insignificant source of CO2 emissions in the state will grow by roughly 12 percent by 2030. This increase equates to less than half of a percent of Nevada's 2030 emissions. The projections show that total GHG emissions from the agricultural sector will increase by about 200,000 metric tons of CO2eq in 2030 (versus 2013 figures). Agricultural sector emissions are not projected to surpass the maximum total emissions that this sector achieved in 2001. Overall, these projections show that this sector will continue to be a minor contributor of GHGs in the state. Figure 8-3 shows the historical and projected emissions from the agricultural sector. The vertical dashed line marks the end of historical emissions and the beginning of the projections. 36
