Interactive effects of dung deposited onto urine patches on greenhouse gas fluxes from tropical pastures in Kenya

Quantifying Beetle-Mediated Effects on Gas Fluxes from Dung Pats

Agriculture is one of the largest contributors of the anthropogenic greenhouse gases (GHGs) responsible for global warming. Measurements of gas fluxes from dung pats suggest that dung is a source of GHGs, but whether these emissions are modified by arthropods has not been studied. A closed chamber system was used to measure the fluxes of carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2...

Interactive comment on “Smallholder African farms in western Kenya have limited greenhouse gas fluxes” by D. E. Pelster et al

The paper presents a set of flux measurements measured using traditional chamber methods from an area not well accounted for in current GHG measurement budgets (rural Africa). It is true that data is required from these areas to better account for gas fluxes in the region; however the broad approach and limited number of measurements used in this paper to estimate annual flux values is unlikely...

Greenhouse gas emissions from dung pats vary with dung beetle species and with assemblage composition

Cattle farming is a major source of greenhouse gases (GHGs). Recent research suggests that GHG fluxes from dung pats could be affected by biotic interactions involving dung beetles. Whether and how these effects vary among beetle species and with assemblage composition is yet to be established. To examine the link between GHGs and different dung beetle species assemblages, we used a closed cham...

Limits of agricultural greenhouse gas calculators to predict soil N2O and CH4 fluxes in tropical agriculture

Demand for tools to rapidly assess greenhouse gas impacts from policy and technological change in the agricultural sector has catalyzed the development of 'GHG calculators'- simple accounting approaches that use a mix of emission factors and empirical models to calculate GHG emissions with minimal input data. GHG calculators, however, rely on models calibrated from measurements conducted overwh...
