The rangelands, as one of the largest dynamic biomes in the world, have very capabilities. Regulation of greenhouse gases in the Earth's atmosphere, particularly carbon dioxide as the main these gases, is one of these cases. The attention to rangeland, as cheep and reachable resources to sequestrate the carbon dioxide, increases after the Industrial Revolution. Rangelands comprise the large par...

Intensive pine plantation management may provide opportunities to increase carbon sequestration in the Southeastern United States. Developing management options that increase fi ber production and soil carbon sequestration require an understanding of the biological and edaphic processes that control soil carbon turnover. Belowground carbon resides primarily in three pools: roots, necromass (lit...

We use a net present value framework to examine the impact of non-permanence on the economics of land-based biological carbon sequestration. Contingent on assumptions about discount rates, management, and carbon prices trajectories, and payment contract design, we find the adjusted value of carbon sequestration relative to permanently available emission offsets to be between 38 and 55 percent f...

Forest ecosystem could significantly sequestrate some atmospheric CO2 and, therefore, partly mitigate current pressure on global warming. The carbon sequestration capacity of forest ecosystem is determined by both the NPP increase trend and turnover time. In order to estimate the capability of forest C sequestration in China, a carbon turnover model, which bases on NPP increase trend monitored ...

This paper reviews the effects of past forest management on carbon stocks in the United States, and the challenges for managing forest carbon resources in the 21st century. Forests in the United States were in approximate carbon balance with the atmosphere from 1600-1800. Utilization and land clearing caused a large pulse of forest carbon emissions during the 19th century, followed by regrowth ...

In this paper, we study the social efficiency of private carbon markets that include trading in agricultural soil carbon sequestration when there are significant co-benefits (positive environmental externalities) associated with the practices that sequester carbon. Likewise, we investigate the efficiency of government-run conservation programs that are designed to promote a broad array of envir...

In this paper, we present a method to quantify the effectiveness of carbon mitigation options taking into account the ‘permanence’ of the emissions reduction. While the issue of permanence is most commonly associated with a ‘leaky’ carbon sequestration reservoir, we argue that this is an issue that applies to just about all carbon mitigation options. The appropriate formulation of this problem ...

Carbon sequestration is a temporal process in which carbon is continuously being stored/released over a period of time. Di erent methods of carbon accounting can be used to account for this temporal nature, including annual average carbon, annualized carbon, and ton-year carbon. In this paper, starting by exposing the underlying connections among these methods, we examine how the comparisons of...
