Question about methane emissions from drainage and rewetting of organic soils
I'm currently working on an assignment for school. For the essay I'm analyzing methane emissions from members of the EU. Data from commen reporting formats are really helpful but something isn't very clear. As you can see in the picture there are a lot of states who aren't reporting data on methane emissions from drainage and rewetting of organic soils: NA (Not applicable) or NO (Not occurring). I'm pretty sure this kind of methane does occur everwhere in the EU. But why not reporting it? Isn't this against the rules?
My hypothesis would be that there is a lack of national data to make an accurate estimate (But wouldn't that mean that the countries should fill in "NE (Not estimated) instead of NO or NA?).
I've read that there is still great uncertainty about the ultimate impact of a given soil type (including the method of calculation) because a lot of factors, present in the soil, influence the final methane production. Maybe this has to do something with it.
Thank you in advance.
With best regards.
