This study used the Daisy model to evaluate the performance of three BBFs—ammonium sulphate (AS), digestate (DIG), and liquid fraction of digestate (LFDIG)—compared to baseline fertilization (mineral and manure) across ten European cropping systems. BBFs replaced baseline fertilization under three scenarios: (i) full replacement with equivalent total N input, (ii) full replacement with higher total N input due to BBFs' lower (&lt;100%) fertilizer replacement values (FRVs, relative substitution rate of BBF to synthetic fertilizer), and (iii) partial replacement (only manure-N) with equivalent total N input. Results indicated that under both partial and full replacement scenarios with equivalent total N input, AS, DIG, and LFDIG had minimal impacts (&lt;5%) on crop N yield, nitrogen use efficiency (NUE), and total N losses (gaseous and leaching) compared to the baseline. The soil organic N (SON) stocks either decreased or changed more slowly with AS and LFDIG. In scenario ii (higher total N input), BBFs led to increased N yield (2–18%) and N losses (avg. 76%), and decreased NUE (2–25%) relative to the baseline. DIG was the most effective at improving SON stocks (average increase 4.9 ​kg ​N ha⁻¹y⁻¹) and reducing N losses, followed by LFDIG and AS. The impact on N leaching varied, with higher leaching observed in annual cereal-based compared to semi-perennial grass-based systems. Implications are that BBFs should be applied assuming a high FRV (∼100%), ensuring equivalent total N input when replacing baseline fertilization to prevent increasing N losses.</div></div>","PeriodicalId":100522,"journal":{"name":"Farming System","volume":"3 2","pages":"Article 100141"},"PeriodicalIF":0.0,"publicationDate":"2025-02-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143465551","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we used historical sub-national crop data from India (1966–2022), Nepal (2000–2022), and Bangladesh (1971–2022) to measure crop diversification and compare it with the existing sub-district level scale. Crop diversification was measured using the Herfindahl-Hirschman Index (HHI). We found a noticeable increase in overall crop diversification in EIGP during this period but with spatiotemporal variations between the countries and seasons. Furthermore, while comparing sub-national patterns with existing sub-district patterns, we found opposing trends. Our data suggest that sub-national diversification patterns are an aggregate measure that may obscure the diversification pattern at the district, sub-strict, and even community level diversification. Measurements of sub-national crop diversification may appear to have moderate diversification overall, but this could result from some districts having high levels of diversification while others more oriented towards monocropping and a lack of diverse crop rotations.

Perennial rice, a novel no-tillage-based rice system, presents a promising solution with the potential to address many of these challenges. It offers several advantages, such as reduced production costs and labor demands by eliminating the need for repeated land preparation, nursery raising, and transplanting while also lowering environmental impact through energy conservation, soil carbon sequestration, reduced soil erosion, and decreased greenhouse gas emissions. The perennial rice system is gaining traction in China, with the area under cultivation steadily increasing since its release in 2018. Farmers are interested in adopting this system due to its lower labor demand, reduced production costs, and yields and grain quality comparable to local varieties. However, perennial rice brings its own challenges, including yield instability, inconsistency in grain quality, higher irrigation demands, increased risks of pests and diseases, soil sickness, and the lack of suitable agronomic practices, such as optimum crop geometry, weed management, nutrient application, and harvesting techniques. Additionally, it limits crop diversification, making it less suitable for regions with diversified or multiple cropping systems. Despite these limitations, perennial rice demonstrates significant potential in several rice-growing regions worldwide. To fully unlock this potential, focused efforts are needed to develop high-yielding perennial varieties with better grain quality and resistance to pests and diseases. Additionally, region-specific agronomic practices, including optimal crop geometry, effective weed control, innovative nutrient management, and improved irrigation, must be established to optimize this cropping system.</div></div>","PeriodicalId":100522,"journal":{"name":"Farming System","volume":"3 2","pages":"Article 100137"},"PeriodicalIF":0.0,"publicationDate":"2025-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143145195","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, as this is a novel measure within the CAP, its contribution to climate mitigation objectives and the cost effectiveness of the current area payments under the eco-schemes are unclear. This study investigated the cost effectiveness of eco-scheme premiums within the CAP 2023, focusing on their potential to enhance climate protection through Short Rotation Coppice (SRC) in Baden-Württemberg (BW). We used a geospatial economic land use model with a life cycle assessment to evaluate the impact of varying premium levels on GHG emissions. Our findings suggested that increasing the premium to €400 ​ha⁻¹ ​yr⁻¹ could offset up to 1.5% of the current agricultural GHG emissions of BW. However, this effect did vary between 0.1% and 8% due to input uncertainties such as economic factors and mitigation potential. The resulting payments per ton of mitigated CO₂eq ranged from €70 to €454, averaging €140. These results indicated that higher eco-scheme premiums could effectively promote SRC as a climate mitigation strategy, but their cost effectiveness is highly variable. Despite uncertainties in our model framework, which may influence these evaluations, our study provided valuable insights into the potential of eco-scheme premiums for climate protection.

As global warming and climate variabilities increasingly affect most of the rice growing regions including India, it is vital to introduce alternative options to rice-rice monocropping. To address this issue, we developed a climate smart index (CSI) to evaluate the climate smartness of different cropping systems such as, rice-sunflower (R-S), rice-maize (R-M), rice-black gram (R-BG) and rice-green gram (R-GG) compared to a conventional rice-rice (R-R) system grown in the eastern coastal belt of India. Diversifying rice-based cropping systems with legumes and sunflower significantly enhanced system productivity and the partial factor productivity of nitrogen by 33–41% and 40–45%, respectively over the rice-rice cropping system. Further, these systems reduced the global warming potential (GWP) by 46.3–51% compared to the rice-rice system. The soil organic carbon content increased by about 5–7 % due to the adoption of pulse crops. The climate-smart index for rice-sunflower (R-S), rice-black gram (R-BG), rice-green gram (R-GG), and rice-maize (R-M) systems were found to be higher than the rice-rice (R-R) system by 26.5%, 18.7%, 18.7%, and 14.9% respectively, on average across seasons. Hence, incorporating legumes and oilseed crops during the dry/minor seasons of the year in rice-based cropping systems can be proposed as a climate-smart alternative.
