    “…Compared to savanna background fluxes, it was found that GHG flux rates from bomas were elevated by several orders of magnitude, with mean fluxes of 487 ± 8 mg CO2-C m−2 h−1, 325 ± 11 µg N2O-N m−2 h−1, and 3245 ± 234 µg CH4-C m−2 h−1 for active bomas, and 167 ± 52 mg CO2-C m−2 h−1, 610 ± 186 µg N2O-N m−2 h−1, and 3127 ± 1262 µg CH4-C m−2 h−1 for inactive bomas, while surrounding savanna soils only emitted 22.3 ± 18.2 mg CO2-C m−2 h−1, 2.5 ± 2.2 µg N2O-N m−2 h−1, and 0.1 ± 0.7 µg CH4-C m−2 h−1. …”

  3. Reducing emissions from fertilizers: Opportunities and Challenges by CGIAR Climate Change Impact Platform

    Published 2024
    “…During the last 75 years, production, and consumption of mineral fertilizers, particularly nitrogen ones, contributed enormously to achieve food security but also as much as 5% to global greenhouse gas (GHG) emissions. To meet the Paris Agreement 1.5 °C global warming target, emissions from fertilizer production and use must be effectively curtailed. …”

  4. Land use and management effects on soil organic matter fractions in Rohid Ferralsols and Haplic Arenosols in Bindura and Shamva districts in Zimbabwe by Mujuru, Lizzie, Mureva, A, Velthorst, E.J., Hoosbeek, M.R.

    Published 2013
    “…Soil organic carbon (SOC) is a major attribute of soil quality that responds to land management activities which is also important in the regulation of global carbon (C) cycling. This study evaluated bulk soil C and nitrogen (N) contents and C and N dynamics in three soil organic matter (SOM) fractions separated by density. …”

    Published 2015
    “…Analyses of lineage expansions showed two sheep migratory waves at approximately 4.5–6.8 ka (lineages A and B: ∼6.4–6.8 ka; C: ∼4.5 ka) across eastern Eurasia, which could have been influenced by prehistoric West–East commercial trade and deliberate mating of domestic and wild sheep, respectively. …”
