A global study of the Greenhouse Gas Value (GHGV), a quantitative measure to assess the climate regulation service that ecosystems provide, derived from a vegetation model. EU FP7 Operas project.
This study forms part of the OPERAs project, which aims to bridge the gap between ecosystem science and practice.
Terrestrial ecosystems regulate climate by their exchange of greenhouse-gases with the atmosphere. The “Greenhouse Gas Value” (GHGV) is a measure for the greenhouse gas benefit of preserving an ecosystem over a multi-year time frame, or the cost in terms of greenhouse gases when the ecosystem is cleared (see Anderson-Teixeira and DeLucia, 2011). GHGV is an adequate metric to assess the climate regulation service that ecosystems provide and forms a basis for monetary valuation.
This application shows a global study where the contribution of CO2 to GHGV was quantified using the dynamic vegetation model LPJ-GUESS. The application layers visualize GHGV and its changes from pre-industrial periods to future scenarios (1850-2100). Three representations of biogeochemical processes in the model were used: potential natural vegetation (PNV), under the consideration of croplands and land use change (CLU), and considering C-N interaction in natural vegetation (PNV-N). The effect of the three environmental drivers climate, atmospheric CO2 ratio, and land use on GHGV is displayed in separate layers.
