2.2.2. Land use and climate change scenarios
We conducted two sets of simulations, from 2011 to 2050, to estimate the change in soybean productivity after climate change, as follows.
2.2.2.1. Effects of land-use change and change in atmospheric composition on climate as in CMIP5 (RCP8.5)
This group of simulations accounts for the effects of land-use change and the change in atmospheric composition on climate with both land use and atmospheric composition according to the CMIP5 (Coupled Model Intercomparison Project Phase 5) experiment. We assess the RCP 8.5 W m−2 scenario (RCP8.5, Riahi et al., 2011) which assumes that climate change leads to a radiative forcing of about 8.5 W m−2 in 2100, and CO2 concentrations increase from 387 to 541 ppmv from 2011 to 2050. This is considered a high emission scenario and, although it is the most pessimistic among all four IPCC AR5 scenarios, it is also the one that best represents the 2005–2014 emissions (Fuss et al., 2014).
