To investigate how agricultural inputs, climate fluctuations, and their interactions affect the temporal stability of grain production, this study compiled multisource provincial-level data in China from 1991 to 2020 at 5-year intervals and calculated time-detrended stability indices for both grain production and yield. The results indicated that precipitation fluctuation during the crop-growing seasons and natural disasters significantly reduced both grain production and yield stability, while the effect of temperature fluctuation was less substantial. The negative impacts of nitrogen fertilizer application on grain stability highlighted the importance of considering and addressing ecological degradation; furthermore, interaction terms reveal that it underscores the vulnerability of grain production and yield stability to climate variability, particularly to precipitation fluctuation. By contrast, irrigation benefits grain stability by satisfying water demands and demonstrates a mitigating effect on risks from precipitation fluctuations.

Urban agriculture (UA) is considered a strategic approach to reducing urban food insecurity. Although there is a growing body of research on urban agriculture, evidence on integrated urban crop-livestock farming systems is scarce. This study aims to fill this knowledge gap by identifying the precursors of food security among urban households practicing different urban agriculture (UA) systems and analyzing the impact of integrated crop-livestock (ICL) systems on household food security in Kumasi Metropolis, Ghana. Our findings indicate that different sets of factors affect the food security of households practicing different urban agriculture systems. However, we observed that household income is negatively correlated with urban food insecurity across all forms of urban agriculture. Access to vacant land improves dietary diversity for households without farms, with crops, or those practicing integrated crop-livestock farming, while access to credit enhances dietary diversity for households without farms, with livestock, or integrated crop-livestock farming. The findings indicate that households practicing ICL farming systems have greater access to food and more diversified diets than households practicing other UA systems. The ICL farming system increases urban households' access to food by 84% compared to households without a farm, 48% compared to households with only crops, and 37% compared to households with only livestock. Households without land remain reliant on food purchases, which are impacted by rising costs. Furthermore, the ICL farming system enhances urban households' dietary diversity by 12%, 7.6%, and 16% compared to households without a farm, with only crops, or with only livestock, respectively. Therefore, the incorporation of ICL farming into urban planning is crucial for improving access to food and diversified diets.</p>","PeriodicalId":54283,"journal":{"name":"Food and Energy Security","volume":"14 3","pages":""},"PeriodicalIF":4.0,"publicationDate":"2025-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/fes3.70100","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144171807","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}

We evaluated the genotypic diversity in plant morphology, photosynthetic responses, metabolite shift, and their relationship in 23 genetically diverse barley inbreds under control, dry down (DD), and moderate drought (MD) stress. DD triggered strong inhibition of photosynthetic health, while reducing plant size was the key strategy under MD stress. We observed that the induced changes under both stress scenarios occurred in a genotype-dependent manner. Compared to control conditions, the metabolism of simple sugars and polyhydroxy acids increased in MD and DD, while the maximum accumulation of amino acids, lipids, and phosphates occurred in DD stress. Accumulation of sugars and metabolites with unknown classification was the metabolic signature of drought-tolerant inbreds. Nevertheless, accumulation of a large pool of metabolites, including lipids, polyhydroxy acids, and amino acids in an inbred did not have a positive effect on drought tolerance and might be metabolically costly. The inbred plants’ tolerance to MD and DD originated from the semi-arid or sub-tropical regions, while drought-sensitive inbreds primarily came from temperate regions. Low stomata density, reduced water loss, and retarded growth under drought stress were the key features of inbreds with better survival capacity under severe dehydration.

This study explores the role of L-cysteine desulfhydrase (L-DES), a key enzyme involved in hydrogen sulfide (H₂S) production, in mediating melatonin-induced drought tolerance in bread wheat (<i>Triticum aestivum</i> L.). Wheat plants were treated with 0.10 mM melatonin prior to drought induction, with water availability maintained at 80% (well-watered) or 40% (drought-stressed) of field capacity. Drought stress led to a significant decline in plant biomass, photosynthetic efficiency (Fv/Fm), chlorophyll content, and relative water content, while simultaneously increasing oxidative stress markers including hydrogen peroxide (H₂O₂), malondialdehyde (MDA), and electrolyte leakage, indicating severe cellular damage. Melatonin application mitigated drought-induced oxidative damage by enhancing antioxidant defense mechanisms, scavenging reactive oxygen species (ROS), and reducing lipid peroxidation. It also maintained photosynthetic efficiency by preserving chlorophyll content and stabilizing photosystem II activity. Additionally, melatonin upregulated glyoxalase system enzymes (Gly I and Gly II) to detoxify methylglyoxal and increased L-DES activity and endogenous hydrogen sulfide (H₂S) levels, thereby improving osmotic balance and stress tolerance. The critical role of L-DES was confirmed using DL-propargylglycine (PAG), an L-DES inhibitor, which significantly suppressed melatonin's protective effects. However, co-treatment with sodium hydrosulfide (NaHS), an H₂S donor, reversed PAG's inhibition, highlighting the indispensable role of L-DES and H₂S in enhancing melatonin-induced drought resilience. This study establishes melatonin as a promising bio-stimulant for sustainable wheat production in arid regions and elucidates the interplay between L-DES activity and H₂S signaling in enhancing drought tolerance mechanisms.</p>","PeriodicalId":54283,"journal":{"name":"Food and Energy Security","volume":"14 3","pages":""},"PeriodicalIF":4.0,"publicationDate":"2025-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/fes3.70103","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144140784","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}

Further disaggregation reveals that the negative effect of fatalities is more pronounced for per capita expenditure on both nutrient-dense and less nutrient-dense purchased foods, compared to their home-produced counterparts. Furthermore, our findings indicate that the diminishing effect of fatalities on expenditure for purchased and home-produced food remains robust across alternative estimation methods and varies across gender, age cohort, and landholding status. Importantly, maize price variability emerges as a key mechanism through which fatalities reduce households' consumption of both market-sourced and home-produced diets.

Therefore, there is a need to develop adaptive and resilient crop varieties for sustainable crop production and food systems. Sorghum [<i>Sorghum bicolor</i> (L.)

Sorghum grain yield is low in arid and semi-arid regions, with a mean of 0.9 t/ha compared to the global average of 2.5 t/ha due to a lack of improved varieties tolerant to recurrent drought and heat and biotic constraints and desirable product profiles. Integrative breeding for early maturity, high harvest index, and water use efficiency (WUE) is an economical and sustainable strategy to improve sorghum productivity and mitigate drought effects.

This suggests that applying chloride to the leaf canopy during the late grain-filling stage of cereals might enhance nitrate use efficiency. Hence, it remains uncertain whether foliar-applied chloride at the late growth stage stimulates nitrate translocation from mature to younger leaves. To explore this possibility, two contrasting faba bean varieties were grown in a climate-controlled chamber. Nitrate concentrations of approximately 50 and 93 μg mg FW⁻¹, respectively, were established in leaves by depleting nitrogen in the rooting medium. Based on these two nitrate concentrations in mature leaves, chloride was applied to the leaf canopy. Measurements of biomass, photosynthesis, and nitrate and chloride concentrations in both young and mature leaves revealed that chloride foliar application raised nitrate levels in younger leaves from 7.1 to 9.5 μmol g FW⁻¹ and boosted photosynthesis by approximately 35%. However, one of the two faba bean varieties did not respond significantly to the chloride foliar application. These findings indicate that chloride application facilitates nitrate translocation from mature to younger leaves, potentially improving grain nitrogen supply.
