1) Three alternative methods for predicting deforestation rates at the district level in East Kalimantan were compared: simple historical rate, historical rate adjusted based on reference regions determined by cluster analysis, and spatially explicit modeling of future rates. 2) The predicted deforestation amounts from 2006-2009 generated by each method were compared to actual deforestation over that period. The reference region method, which used the historical rate of similar reference regions, performed best with errors less than 20% of actual deforestation. 3) The presenter suggested using the reference region method for sub-national scale RELs, while using a combination of modeled projections and book-keeping of planned events for project scales.
