“…After analyzing the CF composition of rice production in southwest China from 2004 to 2016, Lyu et al concluded that reducing fertilizer inputs by improving fertilizer utilization was a major method to reduce CF from rice production, which was similar to the conclusions of Sidhu et al [48,70]. Huang et al concluded that fertilizer contributed the most to CF i in rice production by studying the CF of rice under different crop rotation techniques in central China [71]. In this study, the contribution of fertilizer to CF i was also close to 40%, indicating the great potential of reduced fertilizer inputs in reducing CF i in rice production.…”

Rice production is the agricultural activity with the highest energy consumption and carbon emission intensity. Water and fertilizer management constitutes an important part of energy input for rice production and a key factor affecting greenhouse gas emissions from paddy fields. Water–fertilizer integration management (AIM) is an automated water and fertilizer management system for large-scale rice production, which can effectively save water and fertilizer resources. At present, the energy utilization and environmental impact of AIM in rice production are not clear. To clarify whether AIM is a water and fertilizer management measure that combines energy conservation and carbon emission reduction, a comparative study between the widely used farmers’ enhanced water and fertilizer management (FEM) in China and AIM was conducted in this paper. Field experiments were conducted to evaluate the rice yield, carbon emission, energy utilization, and economic benefits of the two management methods. The results showed that AIM reduced water and fertilizer inputs, energy inputs, and economic costs by 12.18–28.57%, compared to FEM. The energy utilization efficiency, energy profitability, and energy productivity under AIM were improved by 11.30–12.61%. CH4 and N2O emissions and carbon footprint were reduced by 20.79%, 6.51%, and 16.39%, respectively. Compared with FEM, AIM can effectively improve the utilization efficiency of water and fertilizer resources and reduce carbon emissions. This study presents a mechanized water and fertilizer management approach suitable for large-scale rice production systems in China. By analyzing rice yield, resource utilization efficiency, and environmental benefits, AIM can serve as a crucial management strategy for enhancing productivity, economic returns, and environmental conservation within profitable rice production systems. In the future, further investigation into the impact of AIM on the microbial mechanisms underlying rice yield formation and greenhouse gas emissions is warranted.

“…Net ecosystem economic benefits are evaluated by a combination of economic output, agronomic inputs and carbon cost, and are calculated as follows (Cai et al., 2018):

\mathrm{NNEB}=\mathrm{Economic}\ \mathrm{output}-\mathrm{Input}\ \mathrm{cost}-\mathrm{Carbon}\ \mathrm{cost},

where NEEB is the net ecosystem economic benefits, economic output is calculated as the product of rice production and its price (Table S2), input cost is calculated as the product of the amount of various agronomic inputs and their prices (Table S3), and carbon cost is calculated as the product of CF and carbon trading price; the carbon trading price is taken as 35.1 $ Mg −1 CO 2 eq (Huang et al., 2022).…”

“…The use of biochar in conjunction with nitrogen fertilizer to improve long‐term soil carbon sequestration capacity, crop productivity, nitrogen use efficiency (NUE) and net ecosystem economic benefits (NEEB), as well as reduce GHG emissions from crop production can offset the impact of global climate change (Bamminger et al., 2018; Liu et al., 2022; Liu et al., 2022). NEEB is frequently applied to evaluate the ecological advantages of various cropping systems based on output, input cost, and carbon cost (Huang et al., 2022). Only a few research, however, have looked at both carbon footprint (CF) and NEEB (Li et al., 2015).…”

The application of biochar and nitrogen fertilizer can increase rice yield, soil organic carbon (SOC) storage and reduce greenhouse gas (GHG) emissions. However, few studies have systematically evaluated the carbon footprint (CF) and net ecosystem economic benefits (NEEB) of paddy ecosystems under long‐term application of biochar and nitrogen fertilizer. Here, the life cycle assessment method was used to quantify the CF and NEEB of paddy fields under different biochar and nitrogen fertilizer application rates in 7 years. Three biochar rates of 0 (B0), 4.5 (B1) and 13.5 t ha−1 year−1 (B2) and two nitrogen fertilizer rates of 0 (N0) and 300 kg ha−1 year−1 (N) were set. The results showed that B2 significantly increased methane (CH4) emission by 38%, decreased nitrous oxide (N2O) emission by 29%, and significantly increased global warming potential by 27% compared with B0. Besides that, biochar application significantly increased ΔCSOC by 87%–173% and reduced CF by 1.6–1.8 Mg CO2 eq ha−1. Among them, CH4 and N2O emissions contributed 46%–95% of total GHG emissions, and the production and transportation of nitrogen fertilizer and biochar contributed 17%–52% of total GHG emissions. Nitrogen fertilizer application can significantly increase rice yield by 85% compared to the N0, which could bring the largest NEEB. Biochar application had a negative influence on the NEEB regardless of N application. This might be attributable to the fact that the economic gains from increased rice production and SOC caused by biochar cannot outweigh the high cost of biochar. These results suggest that the biochar application can significantly improve the SOC sequestration and reduce the CF, but also had negative effect on NEEB in paddy filed.

“…The indirect emissions of CO 2 from agricultural inputs were obviously greater than those from farm operations in each cropping system. Indirect GHG emissions from agriculture inputs under fertilizer, electricity and diesel were higher than other farm inputs (Xue et al, 2016;Jiang et al, 2020;Ling et al, 2021;Huang et al, 2022;Xu et al, 2022). Indirect emissions of GHGs arising from the production of agricultural inputs, fuel combustion, and use of machinery may contribute as much as half of the total GHG emissions (Mosier et al, 2005;Adviento-Borbe et al, 2007).…”

Reducing greenhouse gas (GHG) emissions and quantifying the carbon footprint (CF) of rice-cropping systems in the context of food security is an important step toward the sustainability of rice production. Exploring the key factors affecting emission reduction in rice production is important to properly evaluate the impact of China’s rice-cropping systems on global climate change. This review provides an overview of the direct and indirect CF in rice-cropping systems; analyzes the influencing factors in terms of rice-based cropping systems, varieties and agronomic practices; and proposes mitigation strategies. Different studies have shown that direct and indirect GHG emissions in rice-based cropping systems accounted for 38.3 to 95.5% and 4.5 to 61.7% of total emissions, respectively. And the CFs of ratoon rice, rice–wheat, rice–maize, rice–rapeseed, and rice–fish systems ranged from 316,9 kg CO2-eq kg−1 to 258,47 kg CO2-eq kg−1, which are lower than that in a double-rice planting system. High-yielding rice, drought-resistant rice, and other hybrids can mitigate GHG emissions from paddy fields by 3.7 ~ 21.5%. Furthermore, organic matter, water, tillage, straw incorporation, conservation tillage, reduced nitrogen fertilizer use, and added biochar and methane inhibitors could reduce emissions. Therefore, through reasonable agronomic measures, variety selection and optimal layout of rice-based rotation systems, the carbon neutral rate of rice production can be improved to help the national carbon sequestration and emission reduction target.
