However, it remains unclear if crop yield and soil fertility can be sustained in the long term under the combined application of organic and inorganic fertilizers. Three long-term field trials were conducted to investigate the effects of organic amendments on the grain sustainable yield index(SYI), soil fertility index(SFI)and nutrient balance in maize–wheat cropping systems of central and southern China during 1991–2019. Five treatments were included in the trials: 1) no fertilization(control);2) balanced mineral fertilization(NPK);3) NPK plus manure(NPKM);4) high dose of NPK plus manure(1.5NPKM);and 5) NPK plus crop straw(NPKS). Over time, the grain yields of wheat and maize showed an increasing trend in all four fertilization treatments at the Yangling(YL) and Zhengzhou(ZZ) locations, while they declined at Qiyang(QY). The grain yield in the NPKM and 1.5NPKM treatments gradually exceeded that of the NPK and NPKS treatments at the QY site. The largest SYI was recorded in the NPKM treatment across the three sites, suggesting that inorganic fertilizer combined with manure can effectively improve crop yield sustainability. Higher SYI values were recorded at the YL and ZZ sites than at the QY site, possibly because the soil was more acid at QY. The key factors affecting grain yield were soil available phosphorus(AP) and available potassium(AK) at the YL and ZZ sites, and pH and AP at the QY site.All fertilization treatments resulted in soil N and P surpluses at the three sites, but soil K surpluses were recorded only at the QY site. The SFI was greater in the 1.5NPKM, NPKM and NPKS treatments than in the NPK treatment by 13.3–40.0 and 16.4–63.6% at the YL and ZZ sites, respectively, and was significantly higher in the NPKM and 1.5NPKM treatments than in the NPK and NPKS treatments at the QY site. A significant, positive linear relationship was found between SFI and crop yield, and SYI and nutrient balance, indicating that grain yield and its sustainability significantly increased with increasing soil fertility. The apparent N, P and K balances positively affected SFI.This study suggests that the appropriate amount of manure mixed with mineral NPK fertilizer is beneficial to the development of sustainable agriculture, which effectively increases the crop yield and yield sustainability by improving soil fertility.展开更多

文摘A significant number and range of challenges besetting sustainability can be traced to the actions and inter actions of multiple autonomous agents(people mostly)and the entities they create(e.g.,institutions,policies,social network)in the corresponding social-environmental systems(SES).To address these challenges,we need to understand decisions made and actions taken by agents,the outcomes of their actions,including the feedbacks on the corresponding agents and environment.The science of complex adaptive systems-complex adaptive sys tems(CAS)science-has a significant potential to handle such challenges.We address the advantages of CAS science for sustainability by identifying the key elements and challenges in sustainability science,the generic features of CAS,and the key advances and challenges in modeling CAS.Artificial intelligence and data science combined with agent-based modeling promise to improve understanding of agents’behaviors,detect SES struc tures,and formulate SES mechanisms.
文摘Background:Antimicrobial resistance(AMR)poses a significant and growing public health challenge in East and Southern Africa.Despite formal commitments to the National Action Plans,domestic financing for AMR remains critically limited,with most countries continuing to depend heavily on external donor funding.Objective:This narrative review examines the current extent to which domestic fiscal commitments align with national AMR policy goals across the two regions.Methods:Government websites for ministries of health and finance,donor platforms,and three academic databases(Scopus,JSTOR,Google Scholar)were searched for eligible articles.National budget statements and media reports were also reviewed where available.Three researchers independently screened titles and summaries,followed by full-text reviews to confirm eligibility.Results:The findings reveal that while several countries have developed National Action Plans,very few have allocated domestic funding to implement them.Only Malawi,Nigeria and Uganda reported modest domestic contributions,while in other countries such as Zambia,Ethiopia,and South Africa,AMR programs remain largely donor-financed or lack dedicated budget lines altogether.Veterinary and laboratory sectors are particularly underfunded,with minimal integration into broader AMR strategies.While this review has several limitations including restricted access to current,comprehensive national budget data and a reliance on secondary sources such as donor and World Health Organization reports,which may introduce bias,the patterns identified in this review still offer valuable insight into regional funding dynamics and can inform future policy and research efforts.Conclusion:We conclude that without dedicated domestic financing and accountability mechanisms,AMR efforts in the region may face significant sustainability challenges observed in other health responses such as human immunodeficiency virus.Strengthening AMR governance requires clear budgetary commitments,sustainable cofinancing models,and policy instruments to reduce dependency on external support.

文摘In recent years,perovskite light-emitting diodes have witnessed a remarkable evolution in both efficiency and luminance levels.Nonetheless,the production of such devices typically relies on protracted synthesis procedures at elevated temperatures and vacuum/inert conditions(e.g.hot-injection synthesis),thus rendering them technically unsuitable for extensive display and/or lighting applications manufacturing.Although alternative synthetic protocols have been proposed,e.g.ligand-assisted reprecipitation,ultrasonic and microwave-based methods,their suitability for the construction of high-performing light-emitting diodes has been reported in only a few studies.In this study,we demonstrate the fabrication of highly efficient lighting devices based on CsPbBr3 colloidal perovskite nanocrystals synthesized by a fast,energetically efficient,and up-scalable microwave-assisted method.These nanocrystals exhibit an impressive photoluminescence quantum yield of 66.8%after purification,with a very narrow PL spectrum centered at 514 nm with a full width at half-maximum of 20 nm.Similarly,the PeLEDs achieve a maximum external quantum efficiency of 23.4%,a maximum current efficiency of 71.6 Cd A^(-1),and a maximum luminance level that exceeds 4.7×10^(4) Cdm^(-2).Additionally,a significantly lower energy consumption for microwave-mediated synthesis compared with hot injection is demonstrated.These findings suggest that this synthetic procedure emerges as an outstanding and promising method towards a scalable and sustainable fabrication of high-quality perovskite light-emitting diodes.
