Carbon sequestration lookup table

Science, Research & Data
1

Hello Stacie and Natural capital team,
I would like to ask about the different source where I can find data to populate carbon sequestration lookup table fro each land use class.
Actually I want to estimate this for Rwanda(East Africa) and local data isnt available
What I can see from IPCC, FAO are estimate for carbon storage but not sequestration
Any help for this?
Thanks

Emmanuel

Hi Emmanuel -

Are you using the Carbon Storage and Sequestration model? If so, you only need to provide carbon storage values in the carbon pool table, you do not need to provide sequestration information. The model will calculate sequestration as the difference in storage between the current and future land use maps you provide.

Hello Stacie,
thank you for your feedback,

Yes am using carbon storage and sequestration model,

As we are developing Ecosystem Account for Rwanda, when it comes to carbon storage and sequestration service we get confused ! We thing this difference in storage between the current and future land might not be considered as sequestration

You may ask yourself what if there have not been any change between the current and future land use land cover maps?? can we say there have been any sequestration??

Actually asked this question referred to some information from Netherland and Austaria about carbon Account, they have carbon storage lookup table and carbon sequestration table differently

See the attachments below

Thanks

Hi Emmanuel -

Our Carbon model is VERY simple, it doesn’t include anything dynamic like growing trees, all it does is map carbon pools to a land cover map and adds them up, and the difference between current and future is sequestration. If your current and future land use maps are exactly the same, then the model won’t show any sequestration.

If you want to show that trees grow (even though the land cover map stays the same), then you can include that in your land cover maps by having your current forest class be something like “forest - young” and forest in the future map be “forest +20 years” and give them different carbon pool values accordingly. It seems possible that if you did have sequestration information, you could translate that into the future carbon value. But then you really don’t need the model, you can just apply the sequestration rates to your land use map manually.

Depending on your purpose, you might want to look for a different carbon model that includes more of the complexity of the real world, like growing trees or changes in soil carbon due to different agricultural activities. Sorry that I’m not familiar enough with other carbon models to make a suggestion.
