“…Additionally, mitigation may take advantage of the fact that, as plants and trees grow, they take CO 2 from the atmosphere through the photosynthesis process and store it in woody trees and soils. Therefore, enhancing the capacity of natural sinks such as forests (Pan et al 2011;FAO 2020) and rangelands, is crucial (McDermot and Elavarthi 2014).…”

“…Rangelands are also an important carbon sink (McDermot and Elavarthi 2014;Derner et al 2017). Globally, 41.3% of the world's land surface is classified as rangelands (MEA 2005;Nosetto et al 2006;Lal 2011;UN 2011;Laban et al 2018).…”

“…Because of their global extent, if properly managed, rangelands have the potential to sequester carbon in woody plants and store organic and inorganic carbon in soils (WRI 2000;IPCC 2007;Derner et al 2017). Some studies show that rangelands can store up to 10-30% of global soil organic carbon (SOC) (Lal 2004;Derner and Schuman 2007;Laban et al 2018) and sequester up to 179.623 Mg of CO 2 from the atmosphere per year (Lal 2011;McDermot and Elavarthi 2014).…”

Many activities from livestock husbandry contribute to emission and concentration of carbon dioxide (CO2), nitrous oxide (N2O) and methane (CH4) gases to the atmosphere; activities such as grazing, manure and urine deposited or stored on land as well as crop farming practices such as tilling, burning of biomass or crop residues. A better understanding of the extent of emission sources and carbon sequestration potential for Eastern Africa rangelands is vital for developing mitigation strategies. In this article, we review the sources of emission with a focus on land conversion for crop farming, livestock husbandry, wildfire/burning and biotic processes such as soil biota activity in the ecosystem. The trade-offs of using rangeland with an emphasis on enhancing carbon sequestration potential are also addressed. This review revealed that many practices that enhance carbon capture process show promising benefits with sink capacity of −0.004 to 13 Mg C ha−1 year−1. However, given multiple land-use and environmental dynamics in Eastern African rangelands, it is imperative to generate more data across various land management and climatic zones in order to ascertain varied sink capacity. Improving carbon sequestration in rangelands through appropriate land management is a promising cost-effective strategy to mitigate climate change. Through improved farming or grazing management practice and restoring of degraded areas, there are significant benefits to enhance carbon sequestration. As rangeland resources are multi-faceted, engaging trans-disciplinary approaches is necessary to allow analyses of co-benefits of improved management or trade-offs degrading.

“…Moreover, future changes in climate patterns might lead to more frequent changes in abiotic factors (i.e., soil moisture and temperature) emphasizing the importance of evaluating how different levels of these two parameters can affect soil CO 2 emissions and soil C storage, which is critical for soil quality and soil resilience against disturbances (McDermot & Elavarthi, 2014). The majority of studies evaluated either how abiotic factors or how litter placement can affect CO 2 emissions from soils; therefore, evaluating the effects of both addresses an important knowledge gap regarding the interactive effect of abiotic factors and litter placement on soil CO 2 emissions (Hibbard et al, 2005; Wang & Fang, 2009).…”

Effects of litter placement, soil moisture and temperature on soil carbon dioxide emissions in a sandy grassland soil

et al. 2023

Semiarid grasslands contribute significantly to global soil carbon (C) storage. Carbon loss from these systems via microbial decomposition is controlled by abiotic and biotic factors such as soil moisture and temperature and C input. Plant litter in these systems can be present above the soil surface or mixed with surface soil by trampling, especially in intensively grazed areas. A quantitative understanding of abiotic factors' interactive effect is critical for predicting soil C dynamics in response to grassland management and environmental conditions changes. Therefore, we conducted a 3‐month laboratory incubation experiment to quantify the impact of litter placement and soil moisture on soil carbon dioxide (CO2) emissions under three controlled temperatures. The treatments including three litter placements (no litter, litter on top and litter mixed with surface soil) and three soil moisture levels (23%, 37% and 50% water‐filled pore space [WFPS]) were incubated at three temperatures (10°C, 20°C and 30°C). Carbon dioxide fluxes were measured every 2 weeks. Soil CO2 fluxes were higher for all moisture and litter treatments initially and declined overtime at 20°C and 30°C. Mixing litter with soil increased the cumulative CO2 emissions by 24% and 19.5% at 20°C and 30°C, respectively, compared to no litter. Also, soil‐litter mixing compared with litter on top showed a 14.3% and 21.6% increase in cumulative CO2 emissions at temperatures of 20°C and 30°C, respectively. At all temperatures, 37% and 50% WFPS resulted in similar cumulative CO2 emissions. The results from this study indicate that rising temperatures from 10°C to 30°C accelerate the effect of soil litter mixing on increasing CO2 emissions compared to litter on top and no litter.
