Policies that change demand for agricultural products ([[Land and biodiversity policies/Agricultural demand|Agricultural demand part]]) are implemented in the agricultural economic model, thus taking into account the impacts on trade and demand in other regions. In IMAGE 3.0, change in wood demand is addressed in the model via a simple relationship with GDP, or by using external input data on wood demand (see Component [[Agricultural economy]]). Demand for second-generation bioenergy crops is addressed in the [[Energy supply and demand|energy model]]. | Policies that change demand for agricultural products ([[Land and biodiversity policies/Agricultural demand|Agricultural demand part]]) are implemented in the agricultural economic model, thus taking into account the impacts on trade and demand in other regions.

Land-use regulation ([[Land and biodiversity policies/Forestry sector|Forestry sector]] and [[Land and biodiversity policies/Land-use regulation|Land-use regulation]] part), which is the regulation of land supply, is modelled as a consistent resource constraint in the [[Land-use allocation|land-use allocation]] model and the [[Agricultural economy|agro-economic model]]. This last model takes account of the economic effects of restricted land supply. For example, {{abbrTemplate|REDD+}} and {{abbrTemplate|PES}} are implemented not as additional productive functions, but by reducing the land supply in the agro-economic model. The spatial dimension of such land-use regulation, like the expansion of protected area, is taken into account in the [[Land-use allocation|agricultural systems]] module, and affects via the resulting land use pattern all down-stream processes. | Land-use regulation ([[Land and biodiversity policies/Forestry sector|Forestry sector]] and [[Land and biodiversity policies/Land-use regulation|Land-use regulation]] part), which is the regulation of land supply, is modelled as a consistent resource constraint in the [[Land-use allocation|land-use allocation]] model and the [[Agricultural economy|agro-economic model]].

Key policy issues
- How can land-use policies contribute to strategies for halting biodiversity loss and reducing greenhouse gas emissions?
- How can changes in consumption patterns contribute to achieving sustainability goals through changes in land use?
- What are the synergies and trade-offs between halting biodiversity loss, food security, reducing nutrient emissions, and reducing water stress?
