“…Then, the contribution of manure N to total N fertilizers increased to 20% by partially substituting synthetic N fertilizer. , This optimization of fertilization was based on the premise that rice yield would not decrease. Energy substitution, saving, and offset (ES). This scenario was designed based on three aspects: substitution of diesel with biodiesel for agricultural machinery operations; electricity saving through optimized irrigation practice; and energy offset benefits generated by converting available straws (excluding straw used for returning and livestock feed) into biogas to replace natural gas Combined scenario (CS).…”

“…Life cycle assessment (LCA) is a systematic methodological framework for evaluating the consumption of resources and environmental impacts associated with various stages of a product . Over the past few decades, the LCA has been widely employed to enhance the understanding of GHG emissions from the production of agricultural products. − Based on the LCA, carbon footprint (CF) was utilized as a comprehensive indicator to encompass all aspects of carbon emissions and carbon sequestration during agricultural production, such as indirect emissions from agricultural materials, direct emissions from field soil, and carbon sequestered into the soil. , Currently, numerous studies have quantified the CF for rice at the provincial or national level, − which provide valuable insights into the GHG emissions from rice production. However, environmental conditions and farming practices exhibit significant variations across diverse rice cropping regions.…”

Under the "Double Carbon" target, the development of low-carbon agriculture requires a holistic comprehension of spatially and temporally explicit greenhouse gas (GHG) emissions associated with agricultural products. However, the lack of systematic evaluation at a fine scale presents considerable challenges in guiding localized strategies for mitigating GHG emissions from crop production. Here, we analyzed the countylevel carbon footprint (CF) of China's rice production from 2007 to 2018 by coupling life cycle assessment and the DNDC model. Results revealed a significant annual increase of 74.3 kg CO 2 -eq ha −1 in the average farm-based CF (FCF), while it remained stable for the product-based CF (PCF). The CF exhibited considerable variations among counties, ranging from 2324 to 20,768 kg CO 2 -eq ha −1 for FCF and from 0.36 to 3.81 kg CO 2 -eq kg −1 for PCF in 2018. The spatiotemporal heterogeneities of FCF were predominantly influenced by field CH 4 emissions, followed by diesel consumption and soil organic carbon sequestration. Scenario analysis elucidates that the national total GHG emissions from rice production could be significantly reduced through optimized irrigation (48.5%) and straw-based biogas production (18.0%). Moreover, integrating additional strategies (e.g., advanced crop management, optimized fertilization, and biodiesel application) could amplify the overall emission reduction to 76.7% while concurrently boosting the rice yield by 11.8%. Our county-level research provides valuable insights for the formulation of targeted GHG mitigation policies in rice production, thereby advancing the pursuit of carbon-neutral agricultural practices.

“…Ultimately, by combining the results of mathematical modelling and product quality analysis, the model elucidates the intricacies of the impact of public policies on industry development and product quality, offering invaluable information for policy makers and stakeholders. Let Pν(t) be the amount of sown feed crop in the process of growth in fields, measured in tons (Wu et al, 2023). The change in this value will be calculated by the formula (1):…”

The livestock industry has experienced rapid growth, and the demand for livestock products is projected to continue increasing quickly due to population growth, improved living standards, and urbanisation. This article aims to assess the feasibility of utilising the created model for growing animal feed for meat-producing livestock during the standard planning phase of economic development. The authors categorise wheat as a reference culture. The study utilised analysis, statistical methods, economic modelling, and mathematical modelling. The authors assess the potential of utilising the created model to cultivate feed for livestock intended for meat production during the standard planning phase of economic development. The model predicts cost-effective feed. The authors’ economic model enables the growth of the feed base, reduces the reliance on imported feed, and facilitates the expansion of meat breeds, which is the unique aspect of the study. The study emphasises the importance of strategically distributing, specialising, and concentrating beef cattle breeding in particular natural and economic contexts. It also highlights the significance of integrating large-scale production with medium and small agricultural enterprises in the meat industry. The study’s practical significance lies in utilising specific structures and controlling the share of imports in feed production, along with restricting feed supply and ready-made food additives to guarantee food security
