“…Via linear regression analysis and multiple regression analyses, the influence of the basic information of the villages on the carbon emissions of the villages is analyzed and discussed, and different energy-saving and emission-reduction strategies are proposed for different types of villages, which provide references for the coastal village planning and rural governance for the purpose of energy saving. The three different types of villages divided by the basic characteristics of villages in this study have different carbon emission pathways, but in the overall situation, the main carbon emission comes from the construction of buildings, and there are some types in which agriculture accounts for a large proportion, which is consistent with previous studies [67], but the importance of agriculture and animal husbandry is different from the results of the latest study [68]; the reason for that lies in the difference in geographical location and the cash crop structure of the villages. From the numerical point of view, there is an obvious gap between the main part of the buildings and traffic stations of the village sample of type 1 and the emission of agricultural and domestic sewage.…”

Rural buildings have high optimization potential as a major source of carbon emissions. However, the current research on carbon reduction in rural buildings is rough and lacks categorization and geographic studies. Coastal villages are more economically developed than other types of villages and have greater potential for energy saving. Therefore, this study takes the carbon emission data of buildings and life in 409 villages in typical coastal provinces of China as the basis and proposes optimization strategies for carbon reduction in coastal village buildings via cluster analysis and correlation analysis. The results show that the carbon emission characteristics of coastal villages can be categorized into three scenarios: for scenario 1, villages, their population, and village cultivated area are the core influencing factors of carbon emission, while for scenarios 2 and 3, the most central influencing factors are coal and electricity consumption. Therefore, different types of villages should be guided differently when studying carbon sinks and carbon emission projections in coastal villages. This study aims to establish a low-carbon performance quality assessment and optimization pathway for coastal villages, and the analysis of carbon emission influencing factors and the assessment and optimization provide theoretical support and quantitative methods for the optimization of carbon reduction in villages.

“…In recent years, the environmental impact of agricultural practices like nutrient management practices has garnered significant attention due to concerns related to climate change and GHG emissions (Menegat et al, 2022;Hemingway et al, 2023). Various studies have indicated the discrepancy that inorganic fertilizers tend to emit more GHGs than organic manures mainly attributed to multiple factors, including nutrient composition (Walling and Vaneeckhaute, 2020), application methods, microbial activity (Jannoura et al, 2014;Tripathi et al, 2020;Yu et al, 2022), and soil management practices (Van Kessel et al, 2013).…”

“…Green manure (T 11 ) increased the retention capacity of nutrients than WS (T 9 ) so resulting in lesser emission intensity. In contrast, the excessive and imbalanced application of inorganic fertilizers can negatively affect soil health, resulting in increased GHG emissions through nutrient runoff and leaching (Hemingway et al, 2023). Thereby, by adopting sustainable practices that promote the use of organic manures such as FYM and GM, farmers can reduce GHG emissions intensity (Gorjian et al, 2022) and mitigate the negative environmental impact of agricultural activities.…”

A long-term field experiment was conducted to study the effects of different combinations of integrated nutrient management (INM) on carbon sequestration and wheat yield in a rice-wheat cropping system. The experiment consisted of 11 treatments that were replicated three times. The organic manures used in the study included farmyard manure (FYM), wheat straw (WS), and green manure (GM) with Sesbania aculeata. The results of the experiment revealed that the application of 50% of the recommended dose of fertilizers (RDF) along with 50% nitrogen (N) through FYM during rice cultivation, and RDF during wheat cultivation, led to a significant increase in soil organic carbon (SOC). Specifically, the SOC content was enhanced by 46.4% (18.29 Mg ha-1) compared to RDF in rice and wheat, resulting in a C sequestration rate of 0.22 Mg ha-1 year-1. These increases were higher in treatments that combined organic and inorganic inputs. Additionally, the application of 50% RDF and substituting 50% of the nitrogen with FYM during wheat cultivation resulted in a 24.7% increase in grain yield compared to RDF in rice and wheat. The INM treatments, showed significantly (p ≤ 0.05) higher agronomic efficiency (AE) of nitrogen (N), phosphorus (P) and potassium (K), partial factor productivity (PFP) of N, P and K, and carbon pool index (CPI) compared to the application of inorganic fertilizers at the recommended dose. Moreover, the INM treatments also exhibited lower greenhouse gas (GHG) emission intensity. Application of neither chemical fertilizers nor organic manure (T1) resulted in maximum GHG emission intensity (328.1 kg CO2 eq Mg−1 yield). Based on these findings, it can be concluded that the combined use of inorganic fertilizers and organic manures significantly increased crop yield and soil organic carbon sequestration while reducing GHG emissions in a rice-wheat cropping system in the eastern Indo-Gangetic Plains (EIGP) of India.

In addition, there are sectoral or activity specific emission factors and inventory assessments of CH 4 and N 2 O from agriculture and other sectors (Datta et al 2009, Gupta et al 2009, Sharma et al 2011, Bhatia et al 2013, Pathak 2015, Patra 2017, Fagodiya et al 2020, Hemingway et al 2023. According to the recent reports, the agriculture sector has contributed to 74% of CH 4 and 72% of N 2 O emissions in 2016 (figure 1).…”

The Indian agriculture sector is driven by small and marginal farmers and employs two-thirds of the Indian work force. Agriculture also accounts for around a quarter of the total greenhouse gas emissions, mainly in the form of methane (CH4) and nitrous oxide (N2O). Hence, agriculture is an important sector for India’s transition to net-zero emissions and for the achievement of the sustainable development goals. So far, very few studies have assessed the future trajectories for CH4 and N2O emissions from the agriculture sector. Moreover, assessment of CH4 and N2O mitigation potential at a subnational (state) level is missing but is important owing to the regional diversity in India. To fill this gap, we focus on methane and nitrous oxide emissions from the agricultural activities using 23 sub-regions in India. We use the GAINS modelling framework which has been widely applied for assessing the mitigation strategies for non-CO2 emissions and multiple air pollutants at regional and global scales. We analyze a current policy and a sustainable agriculture scenario using different combinations of structural interventions and technological control measures to inform the Indian and global climate policy debates. Our results suggest that a combination of sustainable agricultural practices and maximum feasible control measures could reduce the CH4 and N2O emissions by about 6% and 19% by 2030 and 27% and 40% by 2050 when compared to the current policies scenario with limited technological interventions. At a sub-national level, highest mitigation potential is observed in Uttar Pradesh, followed by, Madhya Pradesh, Rajasthan, Gujarat, Maharashtra, Andhra Pradesh, and Telangana. The mitigation of agricultural CH4 and N2O also has co-benefits in terms of reduced local pollution, improved health, and livelihood opportunities for the local communities.
