Baseline and Monitoring Methodology for the Rewetting of Drained Peatlands used for Peat Extraction, Forestry or Agriculture

PRC-RDP

This methodology outlines procedures for estimating the reduction of net greenhouse gas (GHG) emissions resulting from project activities that rewet drained peatlands in temperate climatic regions. It allows for the estimation of GHG emissions from drained and rewetted peatlands and also accounts for changes in carbon stocks in selected non-peat carbon pools.

The scope of this methodology is essentially limited to project activities designed to rewet peatlands that have been drained for forestry, peat extraction or agriculture, but where these activities are not or are no longer profitable. Post-rewetting activities are limited to forestry, agriculture, nature conservation/recreation or activities that aim to reduce GHG emissions, or any combination of all these.

This methodology uses ground vegetation composition and water level as proxies for peatland GHG emissions, known as the Greenhouse Gas Emission Site Type, or GEST, approach.

This methodology was open for public comment from 13 December 2011 until 12 January 2012. Public comments are closed.

Methodology calls for "remotely sensed data of adequate resolution" p. 6, and elsewhere "high spatial resolution" p. 59, but never defines "adequate" or "high". Also, there is no accuracy assessment of the remote sensing classifications, which doesn't meet good practice guidelines. The imagery classification methods offered are insufficient. Calls for: use of good practice, but doesn't suggest any; and, following accuracy requirements, but doesn't recommend any.
