Modeling REDD-baselines using IDRISI’s LCM - Step 4

Modeling Future Emissions

Clark Labs is designing a REDD tool within the Land Change Modeler module of IDRISI. This tool will guide the user through the steps of the baseline development and directly produce tables and graphics necessary for reporting. This will result in a tool that can greatly reduce the time and cost in the development of a deforestation baseline, which currently is delaying the finalization of project development for many prospective REDD projects. The project will also include case studies, testing of different REDD scenarios and production of user guidelines. The tool will be co-designed by the Center for Applied Biodiversity Science (CABS) at Conservation International and Clark Labs. CABS will provide all case study data for testing the tool.

Figure 4. The REDD tab facility for the extraction and calculation of future carbon emission for the project area.

The following parameters are required; the reference area, the project area and the leakage area, the starting and ending date of the project and the number of reporting intervals. The carbon pools as well as the sources of green house gases to be included in the project also must be specified. Average carbon density can be entered either as a constant for each landuse or as a continuous surface image of carbon.

This information combined with the predicted landuse for the REDD project generates a series of tables of future emissions. These emissions estimates must be included in the final project to be submitted to VCS for approval.


  1. bom eu vo olhar depis e postar alguns videos

  2. So, when will the REDD tool be finished?
