REDD - Reducing Emissions from Deforestation and Degradation

Reducing Emissions from Deforestation and Forest Degradation (REDD) is a climate change mitigation strategy employed by conservation organizations, project developers and governments in developing countries. Land Change Modeler (LCM) in the IDRISI software can evaluate REDD related forest conservation strategies and carbon impact scenarios.

LCM is an integrated suite of tools for land change analysis and prediction including a REDD modeling facility to estimate and monitor GHG emission reductions. As a full GIS and Image Processing software, IDRISI includes comprehensive features for processing satellite imagery and developing land cover maps. LCM and IDRISI are fully compatible with international requirements for mapping historical baselines and modeling future scenarios.

Application areas include:

  • Land cover mapping and forest monitoring
  • Historical assessment of land cover change
  • Trend analysis of land cover change
  • Additionality assessment for REDD projects
  • Assessment of potential drivers of land cover change
  • Business-as-usual scenario projection
  • Development of potential future scenarios of land cover: REDD, Infrastructure change, Governance
  • REDD project GHG emission impact accounting
  • Modeling of biodiversity and habitat co-benefit analysis>
  • Modeling ecosystem services impacts
  • Climate trend assessment

Clark Labs offers the following services:

  • Consulting and project planning
  • Training and capacity building
  • Leakage zone assessment
  • REDD rapid assessment
  • Custom software development   

Analytical Examples:


The first stage of a REDD project is the understanding of the historical trends in land use change. The Change Analysis tab in Land Change Modeler provides tools for the rapid assessment of change, allowing one to generate a series of evaluations of gains and losses, net change, persistence and specific transitions both in map and graphical form. This figure shows the historical pattern of change in the Ankeniheny-Mantadia Corridor in Madagascar.

The REDD tab in LCM provides a full accounting of CO2 and non-CO2 baseline emissions for a REDD project area and the reductions that would be expected as a result of REDD project activities. A set of 19 tables are generated following the logic of the World Bank’s BioCarbon Fund methodology.
