Peat and Repeat: Can Major Carbon Sinks Be Restored by Rewetting the World's Drained Bogs? The logging of palm trees grown atop the decaying peatlands of Borneo and Sumatra helps drive the economy of Indonesia, and this fact alone is starting to make the nation a top global priority for efforts to mitigate the warming climate. The problem is three-pronged: First, cheap pulp and paper produced in Indonesia winds up in the glossy coated products we know as junk mail, luxury shopping bags or children's books. Then, once the original trees are gone, palm oil plantations are often planted in their place. Finally, and most importantly from the perspective of the global climate, all of this is happening on top of peat--essentially dead plants that have remained wet under swampy conditions--which is drained as a result of all this activity. Globally, such degraded peatlands emit nearly three billion tons per year of carbon dioxide that was previously locked up in the decaying matter, or roughly 6 percent of all such greenhouse gas emissions from human activity.
