Direct Nitrous Oxide Emissions From Tropical And Sub-Tropical Agricultural Systems - A Review And Modelling Of Emission Factors.

ABSTRACT: There has been much debate about the uncertainties associated with the estimation of direct and indirect agricultural nitrous oxide (N₂O) emissions in developing countries and in particular from tropical regions. In this study, we report an up-to-date review of the information published in peer-review journals on direct N₂O emissions from agricultural systems in tropical and sub-tropical regions. We statistically analyze net-N₂O-N emissions to estimate tropic-specific annual N₂O emission factors (N₂O-EFs) using a Generalized Additive Mixed Model (GAMM) which allowed the effects of multiple covariates to be modelled as linear or smooth non-linear continuous functions. Overall the mean N₂O-EF was 1.2% for the tropics and sub-t
