Winter wheat, which requires vernalization to trigger reproductive growth, is particularly vulnerable to heat, while spring wheat faces limitations due to short and hot vegetation periods. Facultative wheat, which does not require vernalization and can be planted in either fall or spring, offers potential flexibility and resilience to fluctuating temperatures. This study aimed to evaluate the development and grain yield of facultative, spring, and winter wheat varieties under different nitrogen fertilization rates in current climate conditions. Facultative wheat, grown as either facultative winter (FWW) or facultative spring (FSW), along with winter (WW) and spring wheat (SW) varieties, was cultivated over two consecutive seasons (2020–2022) at Ferdowsi University of Mashhad, Iran. Developmental stages were monitored, and grain yield, protein, and nutrient concentrations were measured at four nitrogen levels (0, 100, 200, and 300 kg N ha<sup>−1</sup>) in both shoots and grains. Crop modeling under the RCP 8.5 climate scenario supported the experiments and projections. Facultative wheat sown in autumn exhibited a shorter tillering stage and a longer early reproductive stage compared to winter wheat. While nitrogen fertilization delayed development, it significantly increased yield. Facultative wheat achieved higher grain yields at conventional nitrogen levels (100–200 kg N ha<sup>−1</sup>). Additionally, increasing nitrogen fertilization improved grain protein and nutrient concentrations (N, P, and K). Crop modeling indicated that facultative varieties sown in winter could offer greater yield stability and might benefit from a more consistent phenological development. Overall, facultative wheat performed better at conventional nitrogen levels, highlighting its potential in a changing climate in West Asia. Optimizing sowing dates and nitrogen fertilization could help mitigate some of the negative effects of rising temperatures, enhancing wheat resilience and productivity.</p>","PeriodicalId":54283,"journal":{"name":"Food and Energy Security","volume":"14 2","pages":""},"PeriodicalIF":4.0,"publicationDate":"2025-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/fes3.70072","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143595098","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}

Marginal and small farmers who are resource-poor and risk-prone to a variety of situations are practically illiterate, have financial difficulties, and have small, dispersed properties that are not fit for high-tech agricultural apparatuses. Farming itself became nonprofit over time because of rising costs and uneconomical holding sizes due to fragmentation of land holdings and resource degradation, which posed a grave threat to agriculture's ability to remain sustainable. In terms of Indian agriculture, large-scale urbanization, industrial development, and infrastructure growth have made it necessary to focus on vertical growth rather than horizontal expansion. To address such challenges, there has been broad recognition of the importance of employing farming systems approaches in research. The cultivation of cropping systems with orchard crops and livestock components can play a significant role in the optimal utilization of resources, enhancing energy use efficiency as well as the eco-efficiency index, and reducing carbon footprints. To satisfy the dietary requirements of a household, including food (grains, oilseeds, pulses, dairy products, fruit, honey, fish meat, etc.), feed and fodder for animals, and fuel and fibre for everyday use, attention must be given to the Integrated Farming System which not only satisfies household needs but also enriches the diets of both humans and animals while simultaneously protecting people from the risks of residual toxicity of the chemicals used in agriculture on a large scale.

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<sup>−1</sup>). Significant variations ranging from 2.60 to 6.90 t ha<sup>−1</sup> 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<sup>−2</sup>, grain number per spike, and grain weight by 17.2%, 8.0%, 5%, and 3.2%, respectively, than the lower rate.

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}

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.

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 m<sup>2</sup>) over vegetable cultivation (121.56 USD/100 m<sup>2</sup>) 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.
