Primary data were collected through a cross-sectional survey in three coastal districts, providing comprehensive insights into sociodemographic and economic determinants of food insecurity in this underexplored region. The study included mothers of the children aged 6–59 months from 471 households and selected using a three-stage cluster sampling procedure. Household food insecurity was measured using the Household Food Insecurity Access Scale (HFIAS), and multivariable logistic regression was performed to identify the risk factors of food insecurity. The prevalence of household food insecurity was 28.7%, and a lower chance of experiencing food insecurity was found in households with younger heads (≤ 40 years) [AOR: 0.42; 95% confidence interval (CI): 0.20–0.90] compared to the older group. A lower risk of food insecurity prevalence was observed in households having educated mothers (AOR: 0.22; 95% CI: 0.08–0.58) compared to the noneducated group, higher monthly income (AOR: 0.09; 95% CI: 0.04–0.21) compared to lower income, and households located in the central (AOR: 0.21; 95% CI: 0.10–0.44) and western parts (AOR: 0.15; 95% CI: 0.06–0.34) compared to the eastern coastal region of the country. Household heads engaged in fishing and having mothers with chronic health issues were identified as significant predictors of food insecurity.

Motivated by rising global hunger due to both traditional pressures and newer challenges like energy utilization, this study explores the combined effects of economic, agricultural, and demographic factors on food insecurity. Using panel data from 10 emerging economies (Brazil, China, India, Indonesia, the Philippines, South Africa, South Korea, Russia, Thailand, and Vietnam) over the period 2000–2022, this research examines food insecurity through factors such as agricultural land area, cereal production, population growth, GDP growth, and trade openness.

We employ Fixed Effects, System Generalized Method of Moments (Sys-GMM), and Difference Generalized Method of Moments (Diff-GMM) estimation methods to address endogeneity and country heterogeneity. Empirical findings indicate that higher energy intensity and high population growth exacerbate food insecurity, while increased agricultural land use and increased cereal production significantly alleviate undernourishment.

As climate change is projected to exacerbate these threats, understanding their impact and identifying effective control strategies is crucial. This study aims to determine the impact of these pests on crop yields, household income, and food security, as well as to evaluate the effectiveness of various control strategies using survey data from 1100 farmers in Malawi and Zambia. The descriptive results show that approximately 70% of the farmers experience FAW attacks in their maize fields, approximately 28% experience rosette in their groundnuts, and 40% of the farmers report soybean rust infestations. The econometric results show that FAW, rosette, and soybean rust result in 13.5%, 27.2%, and 25.2% yield loss in maize, groundnuts, and soybean, respectively. We also find that the FAW negatively affects income and food security. While rust, rosette, and their combination had no significant effect on income and food security, their combination with FAW led to a greater negative impact than the FAW alone. Although farmers employ multiple strategies to control these pests/diseases, we find evidence, albeit not robust to different estimation strategies, that pesticides, crop rotation, and the use of improved seeds aid in reducing the negative effect of pests/diseases on crop yields. These findings contribute to the growing body of evidence that can inform policies and interventions aimed at enhancing food security and supporting resilient farming systems in sub-Saharan Africa.</p>","PeriodicalId":54283,"journal":{"name":"Food and Energy Security","volume":"14 3","pages":""},"PeriodicalIF":4.0,"publicationDate":"2025-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/fes3.70078","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143914256","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 study used Central Asia as a case to integrate Partial Least Squares Structural Equation Modeling (PLS-SEM) with particle swarm optimization least squares support vector machine (PSO-LSSVM) to separately identify the drivers of grain supply and demand and enhance prediction accuracy. We analyzed the interannual variations in the production, import/export volumes, consumption, and inventory of wheat, rice, barley, maize, and other grains in Central Asia (1992–2019). We then decoupled the factors affecting wheat production and consumption using PLS-SEM and made predictions by integrating PLS-SEM with the PSO-LSSVM. The results showed that grain supply and demand across Central Asia, primarily driven by wheat production and consumption, declined and later recovered, with a turning point between 1995 and 1998. Kazakhstan exports 44% of its wheat, whereas other countries heavily depend on imports. In Central Asia, the path coefficients (<i>r</i>) of the wheat area and yield on total production were 0.36 and 0.77, respectively, whereas in Kazakhstan, they were 0.37 and 0.81, respectively. Climate and cultivation factors indirectly affect production through wheat yield, whereas yield and consumption influence production through area. Economic growth increased wheat consumption, whereas urban population growth decreased it. In Kazakhstan, wheat exports reduced consumption (<i>r =</i> −0.23) but boosted the economy (<i>r =</i> 0.33), a pattern that was not observed in Central Asia. The coupling model of PLS-SEM and PSO-LSSVM enhanced the prediction accuracy of wheat yield, reducing the error by 10.21% in Central Asia and 32.8% in Kazakhstan.

This study examines the roles of melatonin and hydrogen sulfide (H<sub>2</sub>S) signaling in mitigating Fe deficiency stress by improving Fe bioavailability and enhancing plant resilience. Strawberry plants were cultivated under Fe-sufficient and Fe-deficient conditions and treated with 100 μM melatonin and 3 mM dl-propargylglycine (PAG), an inhibitor of L-cysteine desulfhydrase (L-DES), which regulates H<sub>2</sub>S production.

Melatonin application alleviated Fe deficiency effects by enhancing Fe utilization, stimulating L-DES activity, and promoting H<sub>2</sub>S production. Melatonin also improved antioxidant defenses by boosting the activities of superoxide dismutase (SOD), catalase (CAT), and peroxidase (POD), as well as maintaining ascorbate-glutathione (AsA-GSH) redox dynamics. The addition of 3 mM PAG inhibited L-DES activity, resulting in reduced H<sub>2</sub>S levels and diminished melatonin-induced benefits, underscoring the essential role of L-DES-mediated H<sub>2</sub>S synthesis.

To characterize the plant type and lodging resistance of the optimal UAS population and to distinguish it from other unmanned planting methods, a 2-year field experiment was conducted. Four UAS populations (UAS105, UAS150, UAS195 and UAS240 = 105, 150, 195 and 240 seedlings m<sup>−2</sup>) were established using the inbred <i>japonica</i> cultivar Nanjing5718 as the material, and the appropriate unmanned populations of dry direct seeding (UDDS) and carpet transplanting (UCT) were employed as controls. The results showed that more UAS basic seedlings caused lower grain yield per panicle (9.56%–29.48%), worse leaf and culm configurations, and higher lodging risk (2.43%–9.11% and 0.86%–10.60% in the 2nd and 3rd basal internodes, respectively). But the proper increase (UAS195) improved population yield (3.38%–16.52%), leaf area index (LAI) and grain-leaf ratio. Among the methods, UAS195 ranked behind UCT in all aspects of plant type and lodging resistance, as well as population yield and grain-leaf ratio, and only the LAI excelled. However, it produced more population yield (4.86% on average) and larger panicles (2.02% on average in grain yield per panicle) than UDDS, due to the larger basal and drooping angles, longer pillow distances, and higher SPAD values in high-efficiency leaves, more LAI, and grain-leaf ratio. Furthermore, UAS195 had taller plant height, gravity center height, and basal internodes with more bending moment, but its relative gravity center height and lodging index did not deteriorate significantly. This was attributed to increased breaking strength from stronger internodes with thicker walls. The findings suggest that the optimal increase in UAS basic seedlings (UAS195) could produce more population yield by improving photometric area and grain-leaf ratio, despite compromises in plant type and lodging resistance. Furthermore, not comparable to UCT, but it provides better vertical canopy structure and population yield than UDDS and maintains similar lodging resistance.</p>","PeriodicalId":54283,"journal":{"name":"Food and Energy Security","volume":"14 2","pages":""},"PeriodicalIF":4.0,"publicationDate":"2025-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/fes3.70083","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143827045","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}
