Average carbon sequestration rates in the main types of terrestrial and marine habitats

The figure illustrate the average levels of carbon sequstration rates in marine and terrestrial ecosystems. The “x” in the figure represents the average level whereas the green and blue boxes signify the median values and the range is characterised by the individual dots. For further explanation of uncertainties see Box 1. For more detailed information on datasets please use the linked dataset.

Methodology

Scientific literature shows a wide range of information on carbon stocks and carbon sequestration rates, both qualitative and quantitative. It, however, also shows a very wide range of methods applied. For example, studies have focus on different ecosystem components and carbon storage ecosystems, different demarcation of ecosystem components, carbon storage or ecosystem productivity (GPP, NPP, NEP), different time scales, or report measured or modelled data. These methodological differences influence the range of the carbon storage and sequestration rates reported and complicate mutual comparison. In our study we mainly used expert assessment for the comparison. A more elaborated scientific basis was beyond the scope of this study, but is recommended for further studies.

Units

The carbon sequstration rates are expressed mass per area per time unit (Mg C ha^-1 yr^-1). That is Mg C ha^-1 yr^-1: Megagramme carbon per hectare per year.
