Abstract
In order to examine how varying the length of the calibration and validation intervals impacts the figure of merit, forest loss was simulated in Maranhao & Tocantins, Brazil from 2000-2020. By increasing the calibration and validation interval in yearly increments, the resultant FOM is compared. The FOM was found to increase as the length of the calibration and validation interval was increased. Additionally, the FOM decreased as multiple driver maps were added. Multiple resolution validation resulted in larger figures of merit at coarser resolutions. The results indicate that adjusting the calibration and validation interval and coarsening the resolution of the study area are ways to manipulate a simulation to qualify it as a REDD+ Project.
