Abstract: Tropical ecosystems produce a variety of trace gases playing decisive roles in the atmosphere by triggering the oxidation power as well as the warming potential. Despite their relevance for the regional and global atmosphere a sound understanding of the effect of tropical agroforestecosystems, showing different grades of plant diversity, on trace gas emission is lacking.

A review is presented on trace gas exchange of CH₄, CO, N₂O, and NOx arising from agriculture and natural sources in the world’s semiarid and arid zones due to soil processes. These gases are important contributors to the radiative forcing and the chemistry of the atmosphere. Quantitative information is summarized from the available studies. Between 5 and 40% of the global soil–atmosphere exchange for these gases (CH₄, CO, N₂O, and NOx) may occur in semiarid and arid zones, but for each of these gases there are fewer than a dozen studies to support the individual estimates, and these are from a limited number of locations. Significant differences in the biophysical and chemical processes controlling these trace gas exchanges are identified through the comparison of semiarid and arid zones with the moist temperate or wet/dry savanna land regions. Therefore, there is a poorly quantified understanding of the contribution of these regions to the global trace gas cycles and atmospheric chemistry. More importantly, there is a poor understanding of the feedback between these exchanges, global change, and regional land use and air pollution issues. A set of research issues is presented.
