Effects of Carbon Markets on the Optimal Management of Slash Pine (Pinus elliottii) Plantations

摘要

Global climate change is a growing concern among many policy makers. This concern has led to substantial interest in using forests as one option to mitigate climate change. In this article, the effect of internalizing carbon sequestration benefits onthe optimal management of slash pine plantations is explored. Results suggest that without carbon benefits, it is optimal to use herbicide and bedding but not fertilizer because the increase in timber yield does not justify the high cost of fertilizer. With carbon benefits, however, the use of fertilizer becomes profitable. Thus a carbon market would likely induce plantation owners to increase their management intensity, which may in turn also have significant impacts on the amount of carbon sequestered. For example, by allowing the management regime to vary in addition to rotation age, the amount of carbon sequestered decreased from 204 to 164 metric tons of carbon per acre when carbon prices increased from 40 dollar to 200 per dollar metric ton. Thusincreasing carbon sequestration on the intensive margin may be less feasible than previously supposed, but increasing on the extensive margin may be highly practicable South.
