Estimation of N20 and NO emission from a tropical highland forest in Rwanda

A tropical highland forest in Rwanda, specifically Nyungwe National Park, emerges as a significant but poorly understood source of nitrous oxide (N2O) and nitric oxide (NO), critical greenhouse gases with global warming potential. This study quantifies N2O and NO emissions from the park's soil, contributing to broader estimates for tropical forests—a major yet uncertain component in global atmospheric budgets. By analyzing legacy data, researchers identified key soil properties influencing these emissions, providing a foundation for more accurate regional and global simulations. The findings highlight the need for targeted monitoring of specific parameters to refine predictions, addressing critical gaps in African data and advancing understanding of tropical forest contributions to climate change.
