|Example=The policy interventions that can be analysed are related to either the agricultural economy ([[Agricultural economy]]), or they are reflected in the allocation rules used in the land-use allocation module (e.g. more protected areas, {{AbbrTemplate|REDD+}} schemes). In a study using the OECD Environmental Outlook scenario, the model was used to evaluate impacts of protection levels of natural areas: on top of a baseline scenario with strong bioenergy mandates, it was assumed that 20% (Prot20) of 50% (Prot50) of the land area were protected as nature reserves, or that all forest and woodland was protected from agricultural expansion (see figure below).

The relative reduction in land use and CO<sub>2</sub>emissions differ greatly depending on the type of areas protected. If forests are protected, almost the same amount of agricultural land is used by switching to non-forested land. Thus CO<sub>2</sub>emissions are reduced, but reduction in land use and related biodiversity loss is much less. | ||
