To better understand the tradeoff between high yield and lodging, a diverse set of 15 wheat varieties was tested under two nitrogen application rates (75 and 225 kg N ha⁻¹). Significant variations ranging from 2.60 to 6.90 t ha⁻¹ were observed in grain yield. The lodging index also varied tremendously from 118% to 537% during the two growing seasons. The higher nitrogen application rate increased grain yield, spike number per m⁻², grain number per spike, and grain weight by 17.2%, 8.0%, 5%, and 3.2%, respectively, than the lower rate. Meanwhile, it also increased the lodging index (8.60%), breaking resistance (11.1%), and bending moment (20.5%). The grain yield showed a positive correlation with the lodging index and bending moment and a negative correlation with breaking resistance. The study concludes that remarkable variations exist among the currently grown wheat varieties regarding grain yield and resistance to lodging. Moreover, a higher grain yield, whether due to the genetic superiority of the cultivar or a higher rate of nitrogen fertilizer, was mostly accompanied by an increased susceptibility to lodging. Nevertheless, genotypes with shorter plants, minimum length and dry weight of the third internode, and greater breaking resistance exhibited higher lodging resistance. Meanwhile, the percent increase in grain yield under higher nitrogen levels compared to lower was more than the percent increase in lodging index and can be thus recommended to growers after assessing its environmental implications.</p>","PeriodicalId":54283,"journal":{"name":"Food and Energy Security","volume":"14 2","pages":""},"PeriodicalIF":4.0,"publicationDate":"2025-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/fes3.70071","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143555038","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}

Assessing the resilience of agrifood systems to climate and non-climate hazards helps identify solutions for ensuring the sustainability of farming households. The literature review indicates that a knowledge gap remains in interpreting outputs generated by procedures under various study-specific conditions. A review of selected articles from 1547 documents on resilience among Senegalese farmers identified relevant indices representing farmers' resilience from nine studies, resulting in 83 observations for the resilience index and control variables. This study utilized spatial meta-data and survival regression analysis to examine the effects of regional interactions, shock types, and factor selection on measured resilience through the following phases: (1) Organizing the meta-data, (2) specifying eight meta-regression models to assess bias from regional data variations and the interaction effect of sample size, (3) converting meta-data to survival data to analyze resilience failure exposure and time-to-event failure, and (4) regressing the shock types and agroecological zone conditions on the outcomes from phase three. The results indicated that the “climate hazard” shock, “COVID-19” shock, and “seed diversity effect” were the primary contributors to the highest failure of resilience capacity. The spatial lag significantly affected resilience magnitude. Accounting for the spatial lag changed the negative effect to a positive effect for variables representing different shock types. For example, when accounting for the spatial lag, the impact of “climate hazard” and “other shock sources” shifted compared to the “COVID-19” shock, indicating that their influence on resilience capacity changed direction. The effect of shock-type variables on resilience failure exposure was significant, regardless of whether the shock sources remained constant or changed. The findings emphasize the need for policy considerations regarding measurement procedures, regional factors, and shock-specific interventions to avoid overestimation or underestimation of resilience. For instance, resilience measurement procedures should be improved by distinguishing between permanent and temporary shocks, as well as by considering the vulnerability of interacting regions in comparison to isolated regions. Failure to incorporate these factors may result in an overestimation of resilience for “non-climate” shocks.</p>","PeriodicalId":54283,"journal":{"name":"Food and Energy Security","volume":"14 2","pages":""},"PeriodicalIF":4.0,"publicationDate":"2025-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/fes3.70070","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143554555","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}

Despite growing concern about the impact of slow-onset disasters on food security, most interventions have primarily targeted sudden-onset disasters. As such, there has been limited attention to understanding the effectiveness of adaptation strategies in safeguarding food security during disaster events. The aim of this research was to synthesize all existing evidence on the effectiveness of adaptation strategies in addressing food insecurity during gradual-onset disasters. This study employs Hadley et al.'s food security framework to examine the effectiveness of existing adaptation strategies in mitigating food insecurity concerns during slow-onset disasters. A mixed-method systematic review was conducted using five electronic databases up to July 2023 and followed the guidelines regarding the convergent segregated approach to synthesize the findings. The review showed that most studies (94.1%) focused on drought, neglecting other slow-onset disasters. The strategies mostly focused on ensuring the availability and accessibility of food while giving little attention to food utilization. Most food security components have somewhat identified their effectiveness, except for food safety, with no studies exploring it. Findings from the mixed-methods approach also highlight the double-edged effects of adaptation strategies and the notable absence of reliable intervention evidence using randomized controlled trials. It is crucial for future research to broaden the scope to include the less studied types of slow-onset disasters. Emphasizing neglected and underutilized species, along with food safety aspects, might unveil novel approaches to boost food utilization in fluctuating climates. Given the heterogeneous nature of slow-onset disaster impacts, it is important to explore these dynamic and context-specific aspects of adaptation strategies in different conditions.

However, whether the effect of biochar application on emission intensity (EI) of non-CO₂ greenhouse gas emissions (including methane (CH₄) and nitrous oxide (N₂O)), per unit of crop caloric content, varies for different crops and its driving mechanism remains unclear. Here, we conducted a meta-analysis of EI changes (ΔEI) with biochar application for three major cereal crops: rice, wheat, and maize, based on 202 observations from 41 research publications from Monsoon Asia. Our results showed that biochar application reduced the EI for all three crops by an average of −14.6 kg CO₂ eq M cal⁻¹, with the greatest reduction in ΔEI for rice (−28.9 kg CO₂ equation M cal⁻¹). Biochar application-induced reduction in CH₄ emissions (−0.4 Mg CO₂ eq ha⁻¹) was the main contributor to ΔEI for rice, which was greater than those for upland crops: maize and wheat (−0.1 Mg CO₂ eq ha⁻¹ and 0.3 Mg CO₂ eq ha⁻¹, respectively). Crop type directly affected ΔEI after biochar application. Additionally, crop type indirectly influenced ΔEI by associating with soil organic carbon and clay contents for N₂O emission and CH₄ emission, respectively. This study highlights that biochar application to soil reduces EI across the globally important agricultural region, and these reductions were most pronounced for rice compared to wheat and maize. Our study provides a better understanding of the effects of biochar on GHG emissions for three important crops and can facilitate the development of new strategies for agricultural GHG mitigation while maintaining food security for the future.</p>","PeriodicalId":54283,"journal":{"name":"Food and Energy Security","volume":"14 2","pages":""},"PeriodicalIF":4.0,"publicationDate":"2025-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/fes3.70067","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143530370","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}

Despite extensive research on food security, there still remains a gap in understanding the distinct factors affecting food security within forest communities in conservation zones of the fragile Eastern Himalayas. This study seeks to fill this gap by examining the factors determining household food security among forest villagers in the Buxa Tiger Reserve, located in the eastern sub-Himalayan region of India, which is characterized by significant environmental and socio-economic challenges. Households were evaluated using the Food Insecurity Experience Scale (FIES) and grouped into four levels: food secure, mildly food insecure, moderately food insecure, and severely food insecure. The partial proportional odds model and marginal effects were estimated to analyze the effects of various explanatory variables on the severity of food insecurity. The results revealed that 28% of households were food secure, whereas 72% experienced varying degrees of food insecurity, with a majority falling into the mildly (37.33%) and severely (21.67%) food insecure categories. Key factors influencing food security include the age and education of the household head, landholding size, farming experience, dependency ratio, distance to the bank, and livestock loss due to leopard predation. Additionally, non-farm income, social transfers, and remittances significantly contribute to improved food security.

While prior research highlights its potential as a climate-resilient practice, gaps remain in understanding the determinants of adoption and long-term livelihood impacts. Our study addresses these gaps by examining farming procedures, profitability, impacts, and the key drivers and challenges influencing floating agriculture adoption in southern Bangladesh. Data was collected from 158 farmers using a pre-tested questionnaire between October 2018 and April 2019. Profit function and logit regression models were applied to analyze profitability and socio-economic determinants, complemented by qualitative methods and causal loop diagrams to assess impacts. Findings reveal that farmers employ both intercropping and monocropping, with a preference for seedling raising (156.37 USD/100 m²) over vegetable cultivation (121.56 USD/100 m²) due to higher profitability. Despite its labor-intensive nature (73% labor costs for seedling rising vs. 85% for vegetable cultivation), floating agriculture boosts household income, meets local vegetable demand, and reduces reliance on external markets during shocks. Additionally, it provides ecological benefits such as waterweed management and reduced environmental pollution. Floating agriculture also alleviates poverty by enhancing agricultural production and generating a positive feedback loop of increased income, food availability, and improved nutrition and health. Adoption is influenced by age, experience, family size, income diversity, credit access, extension services, and market proximity. However, high capital costs, limited credit, market volatility, and biotic/abiotic stresses pose challenges. To scale up floating agriculture, policy measures should focus on financial support, technical training, cost-effective innovations, and fostering cooperative farming.

Techniques used in engineering plant metabolism and the innovations being made are helping to improve the nutrient quality of staple foods. Through this approach, scientists have been able to increase the content of essential nutrients, such as minerals, vitamins, fatty acids, and amino acids, to help combat malnutrition and dietary insufficiency in many parts of the world today. The review highlights the genetic and biochemical strategies that can be employed in the management and reprogramming of metabolic pathways to synthesize desired nutrients. This review includes examples of biofortified crops like rice, maize, and potatoes, which have been genetically enhanced to contain higher levels of essential nutrients such as provitamin A, iron, and folate. Furthermore, it examines the application of CRISPR/Cas9 and other advanced gene-editing tools for precision breeding to improve nutrition. Moreover, the review analyzes strategies to ensure that biofortified crops can withstand various environmental stresses exacerbated by climate change. Combining stress tolerance traits, particularly drought stress, with higher nutritional value is important for improving the quality of crops grown under stress conditions. This review synthesizes recent research findings to highlight the potential of metabolic engineering in enhancing crop nutrition. It also emphasizes the importance of adopting multidisciplinary approaches to address regulatory, economic, and societal challenges in the field.
