tion were then calculated using relevant emission factors for each crop. ■ Synthetic fertiliser per hectare and hectares cultivated drive the emissions from synthetic fertilisers used. Synthetic fertiliser per hectare will grow from 65 kg/ha in 2010 to 247 kg/ha in 2030. Synthetic fertiliser use in 2010- 2015 was projected based on GTP targets, and usage growth until 2030 was estimated based on the World Bank 2015 fertiliser application estimate for India (247 kg/ha). ■ Hectares cultivated will grow at 4% over the years based on projections from the GTP, which already includes programmes such as improved seeds and fertiliser use. This will raise the area cultivated from 13 million hectares in 2010 to 27 million hectares in 2030. ■ Livestock population mainly drives the emissions from manure used on land. As projected in the Livestock chapter, the population of livestock will grow from 47 million tropical livestock units in 2010 to 92 million tropical livestock units in 2030. These figures are based on projections by the CSA. GHG emissions baseline and BAU projection for 2030 In the BAU scenario, emissions from soil will increase from 12 Mt CO₂e in 2010 to 61 Mt CO₂e in 2030 (see Figure 49), mainly driven by an increase in the use of synthetic fertiliser. The use of synthetic fertiliser is considered not to stifle the growth of crop reintroduction and manure application as the use of fertiliser on land is expected not to reach the saturation level in the years up to 2030, meaning that the use of crop residue, synthetic fertiliser and manure will all grow along with their emission drivers.
