“…In recent years, increasing attention has been given to indirect carbon emissions from rice production. Indirect carbon emissions in rice-cropping systems emanate from carbon emitted during the use of fertilizer, electricity and diesel oil, fuel combustion, machinery inputs, Fuentes-Ponce et al, 2022). Indirect GHG emissions as a percentage of total emissions under rice-based cropping systems range from 4.5 to 61.7% (Tables 1, 2).…”

“…In the double-season rice and ratoon rice systems, indirect GHGs in the first season accounted for 11.4 ~ 17.3%, and those in the second season accounted for 5.2 ~ 6.8% of the annual total indirect GHGs (Xu et al, 2022). Urea and phosphate fertilizer (to a lesser extent) were the most responsible for increasing indirect emissions (Fuentes-Ponce et al, 2022; Table 3). The indirect emissions of CO 2 from agricultural inputs were obviously greater than those from farm operations in each cropping system.…”

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.

“…The excessive use of chemical fertilizers and pesticides has destroyed the environment, a large increase in agricultural irrigation water has led to over-exploitation of water resources and excessive land reclamation has caused soil erosion and land desertification [4,5]. Agricultural production activities are also one of the important sources of greenhouse gas and carbon emissions, which are constantly increasing [6]. These destructive activities result in impaired functioning of agro-ecosystem services and threaten human well-being [7,8].…”

Nowadays, the challenges of energy depletion, environmental pollution and food security caused by extensive agriculture development are attracting global attention. In China, the construction of ecological farms is a key initiative to effectuate the goal of peaking carbon dioxide emissions and achieving carbon neutrality, contributing to high-quality agricultural development. Based on this, this study selects the national-level ecological farms directories issued by the Ministry of Agriculture and Rural Affairs (MARA) of China in 2021 and 2022, and collects the corresponding economic, social and physical geographic data for GIS spatial analysis and Geodetector. The results are as follows: (1) The distribution of ecological farms in various provinces of China is uneven and spatially clustered. It generally presents a ‘high in the east and low in the west with concentrated cores’ pattern. The construction scope significantly expanded over time, and the high-value areas of nuclear density are concentrated in East China, with the development core transitioned from East China to Central China. (2) Environmental conditions, industrial foundation, economic and social development level, science and technology level and financial support all significantly affect the spatial distribution of ecological farms in China, among which the science and technology level has the most significant enhancement effect on other factors. (3) Environmental conditions provide the construction basis for ecological farms, while economic and social development level and financial support determine the number of ecological farms. The industrial foundation affects the scale of ecological farms in China, while the level of science and technology eliminates the restrictions of other factors to a certain extent. This study provides a reference for optimizing the spatial distribution pattern of ecological farms in China and promoting ecological agriculture. In addition, it presents a viable approach to safeguarding food security.

The emission of carbon dioxide from the soil is an urgent problem, as it not only contributes to climate change, but also affects the reduction of the carbon pool in the soil, which negatively affects its fertility. Cultivation of crops with fast growth, high biomass and atmospheric carbon fixation capacity is effective in terms of reducing soil carbon dioxide emissions and organic carbon storage. The purpose of this work was to evaluate greenhouse gas emissions from the cultivation of industrial hemp (Cannabis sativa L., 1753) in different temperature regimes – 15ºС, 20ºС and 30ºС. Soil without plants was used as a control. The respiration activity of the soil microbial community was assessed on the 1st, 7th, 14th, 28th, 42nd, 56th, 70th, 84th and 98th days of incubation. Biomass of plants was measured on the 98th day. It was established that there were no differences in the respiration activity of the control soil and the soil under industrial hemp (Cannabis sativa L., 1753) at the beginning of the experiment, however, from the 14th day, the respiration activity was significantly lower in the soil without plants. The influence of the temperature regime on respiration activity was established after 56 days of the experiment. The influence of the temperature regime of vegetation on the morphometric parameters of hemp has been established: the largest biomass of plants was found at a colder incubation temperature (15ºС). It has been established that the emission of greenhouse gases from the soil during the cultivation of industrial hemp (Cannabis sativa L., 1753) is higher compared to pure soil and depends on the temperature regime.
