Baseline and Monitoring Methodology for Avoiding Planned Deforestation of Undrained Peat Swamps

August, 2012

This methodology sets out the project conditions and carbon accounting procedures for activities aimed at reducing emissions from deforestation and forest degradation in peat swamp forests and avoiding planned peatland drainage, and therefore falls under the combined AFOLU category of Reducing Emissions from Deforestation and Degradation (REDD) and Conservation of Undrained or Partially Drained Peatland (CUPP) i.e. REDD+CUPP. Only one other applicable methodology exists for REDD+CUPP projects. The proposed methodology differs in some key aspects which may limit the adoptability of the existing avoided planned peat swamp conversion methodology. More specifically, this methodology offers more flexibility in estimating the baseline deforestation rates, includes a procedure to apply hierarchical forest transition to model the conversion process, uses geostatistical techniques to interpolate peat depths between sampling points, and allows for some small-scale deforestation and forest to be present in the project area. Furthermore, this methodology is developed to be compatible with the new VCS PRC guidelines and uses an internationally accepted definition of peat i.e., containing minimum of 30% organic matters and depth of at least 30 cm (as defined by the Internal Peat Society).
