Optimal water management (OWM) is critical for improving crop yield and decreasing N losses. However, few studies comprehensively estimate the effects of different OWM practices (i.e., optimal irrigation rate, time, and technology) on crop yield and N losses, and their water saving potentials. Here, we conducted a global meta-analysis of 562 observations in 103 sites to estimate these effects. Under the current sample support, we found that OWM increased crop yield and irrigation water productivity (IWP) by 2.7% and 19.1%, respectively, while reducing irrigation water use (IWU) by 21.6%. OWM tended to reduce ammonia (NH₃) volatilization and nitrate (NO₃⁻) leaching in several crop-indicator combinations, whereas some optimal irrigation rate and time practices increased nitrous oxide (N₂O) emission. A simplified scenario analysis suggested that broader adoption of OWM could reduce IWU from 1372 to 1075 km³, corresponding to an illustrative water-saving estimate of 297 km³.

The variability in BC feedstocks, pyrolysis parameters, delivery methods and application rates demands optimization to maximize benefits while avoiding unintended effects on plants and beneficial organisms. In this study, we evaluated the concentration dependent effects of pine-derived liquid BC applied to a rockwool based hydroponic lettuce (<i>Lactuca sativa</i>) system under green peach aphid (GPA) (<i>Myzus persicae</i>) herbivory. After germination in water for 14 days, the seedlings were subjected to BC sub-irrigation at 0% (control), 1%, 5%, and 10% BC concentrations and evaluated for plant growth parameters, physiological traits, and aphid performance. Our results show that a single application of liquid BC amendment of 5% resulted in enhanced early seedling vigor when compared to other concentrations and also adversely affected aphid performance. Overall, the findings from this study collectively suggest that 5% BC mediated substrate amendment represents an optimal concentration for managing GPAs in hydroponic lettuce production. The aphids exhibited reduced performance and showed a clear preference against plants that received 5% BC treatment. The results from this study are exploratory and demonstrate that the effects of the pine-BC observed here are concentration dependent, within a single substrate and plant species underscoring the importance of systematic optimization of BC use to fully realize it's potential for sustainable crop production and pest control.</p>","PeriodicalId":54283,"journal":{"name":"Food and Energy Security","volume":"15 5","pages":""},"PeriodicalIF":4.6,"publicationDate":"2026-08-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/fes3.70307","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148807794","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}

To elucidate the molecular regulatory network governing this trait, we systematically evaluated the main agronomic traits and genetic diversity of 40 core germplasm accessions, aiming to identify elite genetic resources. Subsequently, transcriptomic differential expression analysis, weighted gene co-expression network analysis (WGCNA), pathway enrichment analysis, and inter-pathway interaction network analysis were performed on materials with contrasting TGW (high vs. low), with the goal of pinpointing key candidate genes involved in TGW regulation. The phenotypic analysis results indicated that the Shannon-Wiener diversity index (H′) of eight agronomic traits ranged from 1.82 to 2.04, and the coefficients of variation (CV) ranged from 21.83% to 68.14%. Genetic parameter analysis indicated that TGW exhibited the highest broad-sense heritability (87.10%). The GE variance components were significant for all traits (<i>p</i> &lt; 0.05). Meanwhile, for TGW, plant height (PH), and panicle length (PL), these components were significantly smaller than the genotypic variances, except for SW and PD. Cluster analysis classified the 40 germplasm accessions into four groups. Group III exhibited superior overall performance, particularly for TGW, highlighting its application potential in high-yield breeding. Principal component analysis (PCA) extracted four principal components, explaining 84.97% of the total variation. Correlation analysis revealed a highly significant positive association between TGW and both GWMP and panicle weight per main stem (PWMS). Transcriptomic data revealed that pathways related to carbohydrate metabolism, sugar transport, starch biosynthesis, and cell wall formation were significantly enhanced in high-TGW materials, collectively constituting the core regulatory network for TGW formation. Through integrative analysis of multiple datasets, the cell wall invertase gene <i>CIN1</i> was identified as a key candidate gene, whose expression level showed a significant positive correlation with TGW. Furthermore, the transcription factor <i>WRKY50</i> was predicted to regulate <i>CIN1</i>, potentially contributing to TGW determination in foxtail millet.

Yet, critical minerals, which underpin both agricultural inputs and emerging clean energy technologies, remain an under-recognised determinant of modern food security. Recent global disruptions like the 2021–2022 energy and fertiliser price shocks, recovery pressures following the COVID-19 pandemic and the Ukraine war, have demonstrated how mineral and energy supply vulnerabilities rapidly translate into fertiliser scarcity, rising production costs and food price volatility. These events have exposed the close interdependence of mineral, energy and food systems, which highlights the reliance of agricultural production on stable access to energy and mineral-based inputs. At the same time, the global energy transition is increasing demand for critical minerals, particularly copper and other conductive and structural materials required for electrified irrigation, cold-chain infrastructure and agro-industrial processing. However, the concentration of mineral supply chains and export restrictions increase the chances of bottlenecks and price volatility, particularly in regions that depend on imported fertilisers, energy technologies and agricultural equipment. Based on recent empirical and policy literature, this narrative review synthesises three principal pathways through which critical minerals influence modern food systems: (i) fertilisers and soil nutrients (ii) energy and cold-chain infrastructure and (iii) digital agriculture. It further examines how mineral supply concentration, geopolitical risks and overlapping global shocks reshape food system resilience.

Recent studies demonstrate that unprecedented climate warming has threatened global food security, particularly in thermally privileged regions. Yet the impacts of both observed and projected climate change on crop yield potential—especially in thermally constrained mid- to high-latitude zones—are still inadequately quantified. In this study, we investigated the response of maize (<i>Zea mays</i> L.) yield potential to climate warming across Northeast Asia using the Python Package of Agro-Ecological Zones model, integrating both historical observations and future climate projections. Our analysis reveals that climate warming will significantly prolong the growing season between 2020 and 2100 relative to historical baselines. Under the SSP2-4.5 and SSP5-8.5 scenarios, the thermal growing period is projected to extend by 2.02 and 4.15 days per decade (d·decade⁻¹), respectively, while the hydrothermal growing period increased by 1.48 and 2.39 d·decade⁻¹. Our findings further indicate a pronounced northwestward migration of climatically viable maize cultivation zones under both scenarios, with potential areal expansions of 61.02% (5.78 × 10⁵ km²) and 76.73% (7.26 × 10⁵ km²) relative to historical baselines. As a result, the maize climatic yield potential under rainfed conditions is projected to increase at 0.19 and 0.30 t·ha⁻¹·decade⁻¹ for SSP2-4.5 and SSP5-8.5, respectively. Irrigation amplifies these gains, with yield rising by 0.24 and 0.36 t·ha⁻¹·decade⁻¹ under corresponding scenarios. These findings provide robust evidence for maintaining regional food security under climate change, revealing significant untapped potential.

In recent years, the pot-tray mat seedling technique has demonstrated significant potential for producing robust seedlings and increasing the yield in the middle and lower reaches of the Yangtze River. Meanwhile, in cold-region rice production systems characterized by limited heat resources, the interactive effects of seeding rate and seedling age within this technique on comprehensive seedling quality, lodging resistance, and grain yield remain unclear. To address this, a field experiment was conducted using the cold-region japonica rice cultivar Longken 2021 with conventional mat seedling as the control (CK). Four seeding rates (60, 80, 100, and 120 g tray⁻¹, denoted as R1, R2, R3, and R4, respectively) were combined with three seedling ages (35, 40, and 45 days, denoted as A1, A2, and A3, respectively). The results indicated that the pot-tray mat seedling method significantly improved seedling quality compared to the conventional CK, and the combination of low seeding rate and long seedling age (R1A3) increased stem base width and seedling plumpness by 45.8%–46.2% and 11.8%–19.0%, respectively, relative to CK. Regarding lodging resistance, the pot-tray mat seedling method improved stem mechanical properties, and treatments with medium seeding rate and medium seedling age (R2A2 and R3A2) increased the section modulus by 16.5%–24.4% and decreased the lodging index by 15.2%–22.2% compared to CK. For grain yield, the highest values were achieved under the medium seeding rate with medium seedling age (R2A2 and R3A2), which increased yield by 9.2%–24.2% over CK. Although low seeding rates enhanced seedling quality, insufficient basic seedling numbers reduced the number of effective panicles, limiting yield potential. In summary, under the pot-tray mat seedling system for cold-region rice, a low seeding rate combined with a long seedling age favors the cultivation of robust seedlings, while a medium seeding rate combined with a medium seedling age achieves a better balance between seedling vigor and population growth structure, thereby significantly enhancing stem lodging resistance and increasing grain yield. Therefore, considering seedling quality, lodging resistance, and yield performance, the combination of a medium seeding rate and a medium seedling age is recommended as the optimal strategy for pot-tray mat seedling production in cold-region rice, providing a theoretical basis and technical support for high-yield and stress-resistant cultivation.</p>","PeriodicalId":54283,"journal":{"name":"Food and Energy Security","volume":"15 4","pages":""},"PeriodicalIF":4.6,"publicationDate":"2026-08-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/fes3.70297","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148753668","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}

This systematic review synthesizes recent developments in food self-sufficiency research, with a specific focus on how nutritional and dietary dimensions are incorporated. Using PRISMA guidelines, 55 studies were identified and categorized by geographical level, timeframe, data sources, assessment methods, and the extent of nutritional integration. Across the literature, new approaches have emerged that link domestic food production to age- and sex-specific requirements for a wide range of macro- and micronutrients. These assessments consistently reveal major shortfalls in the domestic production of many essential nutrients, particularly calcium, choline, polyunsaturated fatty acids, vitamins A and E, folate, iron, and vitamin B12. For many low- and lower-middle-income countries, international trade only partially improves national nutritional adequacy, leaving large populations vulnerable to “hidden hunger”. Population growth, rising food demand, dietary changes, and environmental constraints are expected to further intensify these pressures. Addressing nutritional self-sufficiency requires context-specific strategies, including improving resource efficiency, reducing food loss and waste, diversifying domestic production toward nutrient-dense crops, promoting healthier and more sustainable diets, and using international trade in a targeted manner to close gaps in critical nutrients and food groups. Future research should focus on filling data gaps in food production and consumption at the level of individual food items and in food composition, particularly for local and traditional food items, generating more reliable food loss and waste estimates, accounting for nutritional degradation, and refining novel nutritional and dietary indicators.</p>","PeriodicalId":54283,"journal":{"name":"Food and Energy Security","volume":"15 4","pages":""},"PeriodicalIF":4.6,"publicationDate":"2026-08-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/fes3.70295","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148752982","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}
