Example: The model can be used to make detailed projections of the energy system, with and without climate policy. In the Rio+20 study, the baseline scenario without climate policy projects a 65% increase in energy consumption in the 2010-2050 period, driven by continued population and economic growth. With no fundamental change in current policies, fossil fuels are expected to retain a large market share as their market price is expected to remain below the price of alternative fuels for most applications. In climate policy scenarios, the inclusion of a carbon price leads to an increased share of alternative technologies and resources, such as carbon capture and storage, nuclear power and renewables (Figure below).

Example: Almost all IMAGE baseline scenarios, including the Rio+20 baseline, project an increase in agricultural production driven by population growth and changes in dietary patterns associated with increasing per capita income (Figure below). Consistent with historical trends, most of the increase is met by higher production per hectare (intensification). In the Rio+20 baseline, slow expansion of the agricultural area in developing countries can be observed, mainly for crops and to a lesser extent for pasture (Figure below). Alternative scenarios explore ways to mitigate agricultural expansion, including the influence of enhanced yield increase, dietary changes, and reduction in post-harvest losses.
