VCS Approves New Methodology for Rewetting Peatlands

26 August 2014

From VCS News

Peatlands in tropical countries are a key carbon sink. Unfortunately, tropical peat forests are often cleared and drained to pave the way for palm oil plantations and other land uses. The process of peatland drainage leads to oxidation of the soil, and hence loss of soil carbon.

To help foster projects addressing peatland drainage, WWF-Germany has developed a new VCS methodology that quantifies the emission reductions and removals achieved by rewetting drained peatlands. This methodology falls within the VCS category of Restoring Wetland Ecosystems, and is the first VCS methodology to address emission reductions and removals associated with rewetting peatlands.

The methodology applies to project activities in which drained tropical peatlands are rewet through construction of permanent or temporary structures such as dams. These structures reverse the pattern of drainage and the damage caused by pre-existing drainage channels. Outputs from the Simulation of Groundwater (SIMGRO) model form the basis of the quantification of emission reductions from which estimates of the water table depth are based given a range of input parameters such as terrain characteristics, peat thickness and climate variables.

This methodology is applicable to projects in the main tropical countries with peatland soils in Southeast Asia; specifically, Malaysia, Indonesia, Brunei and Papua New Guinea.

VCS staff and representatives from WWF-Germany, Remote Sensing Solutions GmbH, Alterra Wageningen UR and SCS Global Services (one of the VVBs who assessed the methodology) will host a webinar providing a comprehensive introduction to this methodology on 16 September 2014 at 11:00am-12:00pm Eastern Daylight Time.
