The future patterns of land use have direct influence on GHG emissions and mitigation potential for land use sector and food supply. The C3IAM/EcoLa model is a global multi-regional land use allocation optimization model, which covers the agricultural and forestry sectors (see the following Figure 1). It can be used to analyze land use change in a long-term period. The primary objective of the model is to minimize the total cost of production under consideration of agricultural demand in 12 regions.
Major types of cost in C3IAM/EcoLa are:
(1) Production costs of crop and livestock production, which are obtained by a total sum of the costs of labor, capital and intermediate inputs divided by the land area obtained from C3IAM/GEEPA;
(2) Land conversion costs which are exogenously determined by the cost of new additional land and investment into infrastructure;
(3) Carbon emissions costs which consider the carbon costs caused by land use change in mitigation scenarios.
