Land use in GCAM is determined endogenously in each period. Land-use change is determined by the land history and its state in the current period. See the description of the GCAM land-use determination in the land sections linked above, as well as in the land [https://jgcri.github.io/gcam-doc/land.html#economic-modeling-approach economic modeling approach].

| Anticipation | GCAM is a dynamic recursive model, meaning that decision-makers do not know the future when making a decision today. After it solves each period, the model then uses the resulting state of the world, including the consequences of decisions made in that period - such as resource depletion, capital stock retirements and installations, and changes to the landscape - and then moves to the next time step and performs the same exercise. For long-lived investments, decision-makers may account for future profit streams, but those estimates would be based on current prices. For some parts of the model, economic agents use prior experience to form expectations based on multi-period experiences. |
Land use in GCAM is determined endogenously in each period. Land-use change is determined by the land history and its state in the current period. See the description of the GCAM land-use determination in the land sections linked above, as well as in the land economic modeling approach page. Land-use change emissions are described here.
