Short summary
We summarized all available data on N-oxides and land use change, which could improve current IPCC tier 1 and 2 approaches for tropical countries. The meta-analysis showed that conversion to (non) fertilized agriculture had the largest effect. Further, we synthesize that the first years after conversion and land management practices are crucial for correctly accounting N2O and NO fluxes. Knowledge gaps remain for degraded forests, peat forests and dominant world crops such as oil palm and soy.
