Rewetting of Drained Tropical Peatlands in Southeast Asia

PRC-RDP

This methodology applies to project types that reduce greenhouse gas (GHG) emissions from peat oxidation by rewetting previously drained tropical peatlands using technical means (eg, the establishment of dams in drainage canals).

This kind of project will have the following effects on greenhouse gas emissions:

A reduction in carbon dioxide (CO₂) emissions due to decreased oxidation of soil organic material;
A reduction in nitrous oxide (N₂O) emissions in nutrient-rich peatlands (not accounted for by this methodology); and
A possible increase in methane (CH₄) emissions (unlikely in the tropics) if the water level after rewetting is maintained near the surface
A possible net positive carbon accumulation in peat (not accounted for by this methodology).

The method doesn't take into consideration, and therefore monitor, any potential impacts of natural disaster or accidental fire. Canopy height measurement is faulty, p. 13. says SRTM DSM to be analyzed with remote sensing image with same time range as SRTM +/- 6months, yet SRTM was created in Feb. 2000. Also the profile spacing for the interpolation of a suitable terrain model is suggested to be just under 5km; this seems much too far to me to be adequate.
