This study assessed the association between functional community health services and community market on household food insecurity and share of food consumption using the seventh round of the Ghana Living Standard Survey (GLSS). Using the multinomial endogenous switching regression (MESR) and accounting for unobserved heterogeneities, we find that the interventions significantly reduce food insecurity.

As a novel agricultural nanomaterial, silicon nanoparticles (SiNPs) demonstrate unique potential in regulating plant stress responses. However, their mechanism of action in forage cold responses remains poorly understood. This study aims to explore the role of SiNPs in the cold tolerance mechanism of <i>Elymus nutans</i> (<i>E. nutans</i>) through physiological and transcriptomic analyses. In this study, <i>E. nutans</i> seedlings were subjected to 3 h and 48 h of cold stress, with SiNPs applied to a portion of the samples. After 3 h of cold stress, the proline (Pro) content in seedlings treated with SiNPs increased by 16.38%. After 48 h of cold stress, the superoxide dismutase activity increased by 7.92%, the Chl content increased by 22.74%, and the abscisic acid (ABA) content decreased by 12.83%. Transcriptomic analysis revealed time-dependent regulatory effects of SiNPs; 3 h cold stress induced photosynthesis-related gene expression, while 48 h cold stress promoted upregulation of ribosome biosynthesis and amino acid biosynthesis genes. Weighted gene co-expression network analysis (WGCNA) identified two core modules (skyblue and floralwhite), enriched in photosynthesis, secondary metabolism, and ribosomal pathways, respectively, which were closely associated with cold-response physiological traits. In conclusion, SiNPs enhance cold tolerance in the QL20-04 (QL) variety of <i>E. nutans</i> by synergistically regulating photosynthetic protection, ribosomal rebuilding, and amino acid metabolism in a stress duration-dependent manner. This study provides novel molecular insights for improving cold adaptation in alpine grasslands and optimizing SiNPs applications in cold-vulnerable agroecosystems.</p>","PeriodicalId":54283,"journal":{"name":"Food and Energy Security","volume":"15 2","pages":""},"PeriodicalIF":4.5,"publicationDate":"2026-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/fes3.70222","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147585180","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While most research has focused on suppressing NH₃ volatilisation through nitrogen source modification, the synergistic role of matching fertiliser types with crop genetic traits remains largely overlooked. Here, we examined the potential of combining controlled-release urea (CRU) with maize varietal selection to mitigate NH₃ emissions in summer maize on the North China Plain, integrating data synthesis with a two-year field experiment (2021–2022). Results indicated an average NH₃ volatilisation rate of 10.35%, strongly governed by nitrogen rate, fertiliser type and maize variety. Field trials evaluated four nitrogen treatments at 180 kg N ha⁻¹—N180U (100% conventional urea), N180C1 (one-third CRU + two-thirds conventional urea), N180C2 (two-thirds CRU + one-third conventional urea) and N180C (100% CRU)—applied to an early-maturing (JNK728) and a late-maturing (ZD958) variety. The results show that compared with other treatments, N180C1 and N180C2 increased the grain yield of JNK728 by 10%–17.4% and ZD958 by 5.5%–24.5% over two growing seasons. Relative to conventional urea (N180U), N180C1 reduced NH₃ emissions by 23.52%–23.56% and enhanced agricultural sustainability by 154.11% for JNK728, whereas N180C2 achieved reductions of 23.62%–27.83% in NH₃ emissions and a 162.63% improvement in sustainability for ZD958. The structural equation model reveals the underlying mechanism: This fertilisation strategy tailored for different crop varieties not only reduces the peak concentration of ammonium nitrogen in the soil but also promotes root growth, enhances nitrogen absorption efficiency and ultimately reduces ammonia volatilisation losses. Our findings establish that coupling CRU with variety-specific management forms a potent two-dimensional plant–nitrogen strategy, effectively curtailing NH₃ emissions while advancing the productivity and sustainability of maize systems.</p>","PeriodicalId":54283,"journal":{"name":"Food and Energy Security","volume":"15 2","pages":""},"PeriodicalIF":4.5,"publicationDate":"2026-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/fes3.70223","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147579782","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Some scholars have pointed out that environmental regulations can disrupt the natural deposition of elements in the atmosphere affecting soil nutrients and, consequently, agricultural productivity. Does this argument apply to countries with more severe pollution control, population pressure, and food security challenges? This study, using the 2007 China sulfur dioxide emission trading as a starting point, reveals the relationship between SDE (Sulfur Dioxide Emissions Trading) and agricultural productivity. The analysis yields the following results: First, SDE can suppress agricultural productivity. Second, the use of organic fertilizers, chemical fertilizers, and mechanized agriculture can mitigate the negative effects of SDE. Reductions in industrial sulfur dioxide emissions represent a potential pathway for mitigating SDE. Third, SDE has a greater negative impact on the output of cotton-growing areas, non-rice-producing areas, and non-fruit-producing areas. Lastly, SDE inhibits local urban agricultural productivity while promoting agricultural productivity in neighboring cities.
