“…Perennial natural vegetation, while comprising only 40% of the farm area, mitigated ∼60% of farm emissions. Our results are in support of commonly identified NCS to mitigate GHG emissions, which include high carbon accumulation capacity of pasture ecosystems with conservative nutrient management (Fargione et al., 2018; Griscom et al., 2017; Voglmeier et al., 2020; Wall et al., 2020). Increasing pasturing in dairy cattle production systems often increases enteric fermentation while also reducing milk efficiency (Beukes et al., 2010), but several studies found overall lower GHG budgets of dairy farms that had greater proportions of pastures on farm (Ribeiro‐Filho et al., 2020) due to lower agricultural intensity.…”

Atmospheric CO 2 concentrations are steadily increasing, with concentrations reaching 1.5 times preindustrial levels (Bloch-Johnson et al., 2021). Natural climate solutions (NCS, also termed nature-based climate solutions) that enhance biospheric carbon sinks and reduce or mitigate greenhouse gas emissions have been proposed to combat this climate crisis, demanding changes in ecosystem management (Griscom et al., 2017;Hemes et al., 2021). In the case of livestock agriculture, several "nature based" strategies have been identified to mitigate

“…Excreta increased CH 4 emissions through deposition effects [116], while emissions decreased over time with aging. According to a study by Voglmeier et al [118], emissions occurred up to 20 days after deposition. Leaching losses of C as DOC were small compared to emission losses of CO 2 [119].…”

This review provides an overview of grassland studies on the effects of manure application and herbivore excreta on plant and soil properties in temperate grasslands. Grass biomass from grazing or mowing is mainly used for animal products such as milk or meat, as well as for energy or raw materials for biorefineries. Manure application or grazing has a significant impact on several plant and soil properties. There are effects on soil chemical properties, such as increased carbon sequestration, improved nutrient availability, and increased pH. Additionally, several physical soil properties are improved by manure application or grazing. For example, bulk density is reduced, and porosity and hydraulic conductivity are greatly improved. Some biological parameters, particularly microbial biomass and microbial and enzyme activity, also increase. The use of manure and grazing can, therefore, contribute to improving soil fertility, replacing mineral fertilizers, and closing nutrient cycles. On the other hand, over-application of manure and overgrazing can result in a surplus of nutrients over plant needs and increase losses through emission or leaching. The lost nutrients are not only economically lost from the nutrient cycle of the farm but can also cause environmental damage.

“…Input data, except for air temperature and CO 2 concentration, was identically allocated to three sets of 59,939 × 60 spatiotemporal units, where each set represented the current climate, RCP 4.5, and RCP 8.5, respectively. With these spatiotemporal units, FBD-CAN simulated photosynthetic CO 2 uptake, respiratory CO 2 emissions (i.e., both autotrophic and heterotrophic respiration), CO 2 absorption (i.e., the difference between photosynthetic CO 2 uptake and respiratory CO 2 emissions), N 2 O emissions, and the GHG budget (in this study, the term denotes the sum of CO 2 absorption and N 2 O emissions) from 2021 to 2080 [56]. We projected the spatial patterns of the GHG budget across South Korean forests for 2021, 2050, and 2080 using the mapping tool in ArcGIS Pro 2.6 [55].…”

Forests mitigate climate change by absorbing CO2. However, N2O emissions in forests, which has 298 times larger global warming potential than CO2, can diminish the climate mitigation role of forests. Thus, it is crucial to project not only CO2 absorption but also N2O emissions in forests to provide a scientific basis for the 1.5 °C Paris Agreement goal. This study used a biogeochemical model, called FBD-CAN, to project CO2 absorption and N2O emissions of South Korean forests from 2021 to 2080 under three climate scenarios, including the current climate, Representative Concentration Pathway (RCP) 4.5, and RCP 8.5. From 2021 to 2080, CO2 absorption decreased from 5.0 to 1.4 Mg CO2 ha—1 year—1 under the current climate with the aging of forests, while N2O emissions increased from 0.25 to 0.33 Mg CO2 eq. ha—1 year—1. Climate change accelerated the decreasing trend in CO2 absorption and the increasing trend in N2O emissions. The subalpine region had a faster decreasing trend in CO2 absorption than the central and southern regions due to its older stand age. These findings provide scientific references for future greenhouse gas reduction plans and broaden our knowledge of the impacts of climate change on the climate mitigation role of forests.
