Load the model “simulate_def_aband_and_deterministic_transition.xml” from \Examples\ sim_defor_and_aband_using_sojourn_time_and_deterministic_transition In this example, transition from abandon (land abandoned undergoes regeneration) to forest is deterministically determined based only on the sojourn time. So after a period in regrowth, the abandoned parcel has acquired a forest structure similar to a mature forest, thereby considered as forest. The minimum sojourn time for this transition to occur is 21 years
