“…In present study, multiple metrics evaluation (CF a , CF m , and CF e ) were adopted in the identification of the optimum intercropping system, which could provide comprehensive references for the analysis of C footprint of different cropping systems (Huang et al., 2019; Yang et al., 2014). Previous studies found that maize‐based intercropping could reduce CO 2 emission from the soil significantly compared to the sole maize system (Beedy et al., 2010; Shen et al., 2018). And C footprint of the maize‐based intercropping was lower than that of the sole cropping system (Cui et al., 2019; Nie et al., 2010).…”

Global agriculture is facing multiple challenges to meet the food demands, optimize resource utilization, and mitigate the climate change. A field study, combined with the life cycle assessment (LCA), was conducted to select the effective and sustainable cropping systems in northwestern China. The study compared four maize‐based intercropping and corresponding monoculture systems on crop yield, evapotranspiration (ET), water use efficiency (WUE), profitability, and carbon footprint (CF). Maize/wheat intercropping had the highest energy yield (532.5 GJ/ha, on average) and maize equivalent energy yield (MEEY) (522.3 G/ha, on average), followed by those from the maize/rape intercropping system, and the lowest by the sole potato system. The WUE of maize equivalent energy yield (WUEMEEY) was the highest (1.06 GJ ha−1 mm−1) for sole rape system, followed by those for the maize/wheat and maize/rape intercropping systems. Maize/potato intercropping had the highest benefit: cost ratio at 3.30, followed by those for the maize/wheat intercropping (2.58), sole potato (2.57), and maize/rape intercropping (2.53). Lower CF and higher net ecosystem economic budget (NEEB) were observed in maize‐based intercropping systems. The maize/wheat intercropping system had the lowest CF per maize equivalent energy yield (CFm) (10.7 kg CO2‐eq GJ−1 year−1), and the maize/potato intercropping system had the lowest CF per unit economic output (CFe) (0.14 kg CO2‐eq US$−1 year−1), and the highest NEEB (7,352.8 US$/ha). The data presented indicate that maize‐based intercropping system may be a viable practice for the synthesized goals of higher productivity and profitability while lesser environmental footprint in a water‐scarce region of northwest China.

“…Other studies on the Loess Plateau obtained similar results (Wan et al, 2009;Yeboah et al, 2016b). Shen et al (2018) indicated that agroecosystems in dry regions with minimal irrigation often act as CH 4 sinks due to aerobic soil conditions. This is due to oxidation of CH 4 under aerobic conditions (Matson et al, 2009;Schaufler et al, 2010).…”

“…In evaluating the effect of intercropping on GHG emissions, Ricord (2018) studied GHG emissions from a sole maize crop, a sole soybean crop and a maize-soybean intercrop and found that the cereal-legume intercropping system effectively reduced N 2 O emissions. In a similar study on the North China Plain, N 2 O fluxes were lower from maize-soybean intercropping than a maize monoculture system in three growing seasons (2013)(2014)(2015), when all cropping systems were applied with 240 kg N ha −1 as urea in two split applications (Shen et al 2018). Shen et al (2018) showed that the fertiliser N loss as N 2 O was lower in the maize-soybean intercropping (1.6%) and soybean monoculture (1.7%) than in the maize monoculture (2.3%), concluding that maize-soybean intercropping should be recommended as a climate-smart cropping systems for use on the North China Plain.…”

A maize-wheat intercropping system coupled with reduced tillage and stubble mulching can increase grain production and decrease C emissions in an arid area in northwest China (Hu et al 2015;Yin et al 2018).…”

Agricultural lands make up approximately 37% of the global land surface, and agriculture is a significant source of greenhouse gas (GHG) emissions, including carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O). Those GHGs are responsible for the majority of the anthropogenic global warming effect. Agricultural GHG emissions are associated with agricultural soil management (e.g. tillage), use of both synthetic and organic fertilisers, livestock management, burning of fossil fuel for agricultural operations, and burning of agricultural residues and land use change. When natural ecosystems such as grasslands are converted to agricultural production, 20–40% of the soil organic carbon (SOC) is lost over time, following cultivation. We thus need to develop management practices that can maintain or even increase SOCstorage in and reduce GHG emissions from agricultural ecosystems. We need to design systematic approaches and agricultural strategies that can ensure sustainable food production under predicted climate change scenarios, approaches that are being called climate‐smart agriculture (CSA). Climate‐smart agricultural management practices, including conservation tillage, use of cover crops and biochar application to agricultural fields, and strategic application of synthetic and organic fertilisers have been considered a way to reduce GHG emission from agriculture. Agricultural management practices can be improved to decreasing disturbance to the soil by decreasing the frequency and extent of cultivation as a way to minimise soil C loss and/or to increase soil C storage. Fertiliser nitrogen (N) use efficiency can be improved to reduce fertilizer N application and N loss. Management measures can also be taken to minimise agricultural biomass burning. This chapter reviews the current literature on CSA practices that are available to reduce GHG emissions and increase soil Csequestration and develops a guideline on best management practices to reduce GHG emissions, increase C sequestration, and enhance crop productivity in agricultural production systems.
